End of the World: My Items Can Be Upgraded Infinitely.

Chapter 159: Unforgettable Skull Smashing, the Unexpected Gain from Destroying the Mother Nest
"Tigertooth Chainsword upgraded!"

"Absorbing the rock-solid attribute, adding an additional attribute: Indestructible Skull Crusher"

「Tiger Tooth Chainsaw Sword lv27/29, orange quality」

「升级点9/10，耐久度：10/10，基础伤害700」

「Additional attribute: Extreme cutting speed (saw teeth rotate five times per second, causing five times the basic damage, upgraded to unlimited endurance mode)
Bloodthirster (Each time you kill a second-level Zerg, you will gain upgrade points and restore a little durability)
Immortal Skull Crusher (If the target's defense value is lower than the basic damage, the durability will not be reduced. If the target's defense value is higher than the basic damage but not higher than the damage per second of the extreme cutting, the durability consumption rate will be reduced by 50%. If the target is killed by chopping the head, the damaged durability will be automatically restored)

"Note: The basic damage will decrease as the durability of the chainsaw sword decreases."

"Note: The host has been detected to have reached level 29. The energy from the two simultaneous upgrades has been stored in the genetic radiation skill for backup."

Lin Feng looked at the new attributes that appeared. The previous immortality should be related to the rock-hardness of the lv29 tiger-spine worm. The opponent's attack does not exceed the defense value, which greatly reduces the damage, while immortality reduces wear and tear.

As for the broken skull later, it should be related to the method used to kill it.

Obviously, cutting the skull was the least effective strategy, but Lin Feng wanted to ensure a fatal blow, so he jumped onto the tiger-back worm's back and chopped off its brain.

With the immortal skull-crushing attribute, you won't have to worry about durability issues in long-term battles. You can just chop at the enemy's head.

However, the scene of being cut in half vertically was a little difficult to get used to at first.

At this moment, the threat of the second-level peak tiger-backed worm was finally resolved. Lin Feng looked at Long Yi behind him with a lot of doubts, and his eyes were shining with golden light.

The opponent's level, after plundering the life energy of dozens of second-level insect eggs, also reached the peak of the second level:
"Longyi, lv29/29, Queen Mother's clone"

"HP 900, Vt 900, SPR 1138"

"Spiritual Conception - Infinite Reproduction"

"The ability to reproduce and evolve indefinitely has been greatly enhanced: mental manipulation, parasitism, gene control..."

Sure enough, after madly absorbing life energy, Longyi has reached incredible strength, and even his spiritual attributes have surpassed himself.

However, her physical condition has always been her shortcoming as a humanoid clone.

It is related to human's natural genetic defects.

Lin Feng was about to ask, but was interrupted by a cough. Turning around, he saw two second-level team members dragging half a figure from the ground.

After taking a closer look, it turned out to be Shen Jie who had just risked his life to resist the thundering attack of the second-level peak tiger-spine worm.

After vomiting blood from his chest, he lost consciousness and the Winged Tiger Berserker form on his body gradually faded, but the Zerg characteristics of his whole body still existed. The assimilation erosion after excessive use was slowly turning him into a Zerg-man.

Seeing Shen Jie unconscious, Lin Feng hurried over. When he got closer, he found that his lower body was deeply sunken in the mud, and the breastplate exposed outside was completely cracked.

Blood was constantly oozing out from the cracks in the skin.

He was seriously injured, and even in Lin Feng's examination, he showed a weak state of near death.

"Don't pull it out! We have to dig him out!"

Lin Feng immediately stopped the team members' actions. Shen Jie was seriously injured and no secondary injury could be caused.

Then several people squatted down, and after quick digging, they finally lifted Shen Jie carefully out of the deep pit.

Lin Feng swung the tiger-tooth chainsaw sword in his hand, killed a second-level insect egg, and poured all the organic nutrient solution in it to Shen Jie who was lying on the ground.

He knew that the other party could absorb it.

Swallowing and assimilating superpowers not only made Shen Jie a natural genetic warrior, but also gave him a good appetite.

Especially organic nutrient solution, which is definitely a rare life-saving treasure.

When the milky white nutrient solution was poured onto Shen Jie's body and into his mouth, it was absorbed by his body and his superficial injuries gradually improved...

But I never woke up.

Lin Feng looked at Long Yi who was walking towards him:

"Is there any way? I feel that the spiritual energy in his brain is becoming weaker and weaker, like a candle in the wind. If it is not improved in time, even if he is saved, he will probably become a vegetable."

Long Yi stared silently at the man under her feet. In fact, she was very interested in this human awakener who could synthesize and evolve naturally.

It was just that Lin Feng had been on guard all the time, so Long Yi had no way to start.

This is the best opportunity. As long as he dies, and then through close study of the corpse, he can find a new route to advance to the fourth level.

By then, even if she could not save the entire Zerg race, she could use this to lead a part of the tribe to escape far away and continue the racial heritage.

But facing Lin Feng's question, perhaps moved by Shen Jie's selfless help, Long sighed. She knew that since she had free will, her personality was undergoing some wonderful changes...

Becoming more and more emotional.

Then he raised his hand and pointed to the hatching meat tower next to him:

"At this point, we can only put it in there and try it out."

"He harvested a lot of second-level insect eggs. He should have gradually upgraded to the late second-level stage, but he risked his life to resist the attack of the second-level peak tiger-spine insect, which stimulated the life energy he had just absorbed and released it in a short period of time..."

"If it weren't for the assimilated ability that made him immune to certain mental shocks like the Zerg, the burst of life energy alone would be enough to shatter his brain."

"Sometimes being promoted too quickly is not necessarily a good thing."

Lin Feng frowned slightly, lifted Shen Jie and carefully placed him next to the meat tower:
"Can you control this hatchery now?"

Lingyi admitted without hesitation:

"In order to control the second-level peak tiger spine worm, the node mother body has weakened its control over the symbiotic mother nest. Taking this opportunity, I have taken control of the hatching nest in front of me, but it can still parasitize on other biological nests. Don't be careless."

"How do you plan to save Shen Jie there? Use your spiritual state of mind?" Lin Feng narrowed his eyes and looked at the fleshy wall.

Then, under the control of Long Yi, a two-meter-long crack formed on the fleshy wall, and layers of folds appeared in the crack. Then dozens of tentacles stretched out from it and slowly pulled Shen Jie next to him into the crack...

Finally, it was sucked into the meat tower and slowly floated up.

Long Yi continued to wave his hands, his eyes flashing with golden light, causing an insect egg embedded in the flesh wall to be cut open from the inside, and Shen Jie, whose armor had been shattered, was stuffed into the insect egg.

At this moment, under the fluorescent light nearby, he was like a developing baby in the womb, curled up with his hands hugging his thighs, allowing the tentacle tubes growing on the egg membrane to connect to his body surface.

At the same time, the permanent assimilated insect armor on Shen Jie's body, which could not be repaired to its original state, also fell off one after another.

It's as if the whole person is experiencing a rebirth.

Lin Feng smiled when he saw this scene. If everyone could do this, it would mean that another defect of the genetic warriors would be perfectly solved.

Ling Yi saw Lin Feng's thoughts and said calmly:
"Don't even think about it. Unless you are willing to take risks, become a genetic warrior, and then master the ability of state of mind, and at the same time spend hundreds of years digesting the advanced biotechnology of the Zerg, it is impossible to achieve this function."

"And its consumption is not low..."

As he spoke, four or five second-level insect eggs were seen, one by one, under the control of Long Yi, all the life energy in them was extracted and injected into the body of Shen Jie who was being rebuilt.

Lin Feng twitched the corner of his mouth. The price was indeed a bit high, but as long as Shen Jie could recover as before, everything would be worth it.

Then he asked:
"How long will it take? The Queen Mother of Jiangbei and No. 76 of Haicheng will probably send reinforcements soon."

Ling Yi shook his head helplessly:
"Shen Jie's condition is not just a simple external injury, but a brain injury. His consciousness has fallen into the spiritual world of the Zerg. Due to the characteristics of genetic assimilation..."

"If he can make it through, maybe he can master his own state of mind and the way to ascend. Otherwise, his consciousness will be lost forever, and he will never be able to wake up again from now on."

"All I can do is to reduce his burden from the outside and reduce the complexity of his spiritual world." Lin Feng frowned slightly:

"If you don't wake up soon..."

Ling waved his hand:
"There's nothing to worry about. We can just take the people and the eggs away with us."

"But before you go, I'll leave these things to you."

Seeing Ling nodded and pointed at the entire meat tower in front of him, Lin Feng instantly understood what she meant.

This is to kill them all and destroy the entire insect nest.

"Hurry up and get rid of all the eggs that have hatched, then protect these red beetles and transport the second-level eggs!"

Lin Feng immediately gave orders, asking the second-level legion team, which had just breathed a sigh of relief, to take action again.

But right now, I have to cooperate with the Red Beetle, which feels indescribably weird.

However, the group could not take away all the second-level insect eggs, so they could only rely on Longyi to control the swarm of red beetles and solve the team's logistical problems.

Soon, the remaining 380 second-level insect eggs were carried away by the giant red beetle group controlled by Ling Yi, including the one that was pregnant with Shen Jie.

Finally, only the lonely hatching meat tower was left, dotted with deep pits, looking even more eerie in the darkness.

After this group of red beetles, under the protection of the second-level legion team, crawled into the depths of darkness, leaving Lin Feng and Long Yi to guard their rear.

Lin Feng raised the lv29 electromagnetic cannon in his hand, aimed at the hatching meat tower, turned around and asked:
"The node mother body is under your control? How come I haven't seen it for a long time?"

Ling Yi shook his head and curled his lips:

"I don't know. I didn't sense it."

"After the second-level peak tiger spine worm was killed, it also disappeared from my spiritual perception. I guess it hid in a biological nest, but it definitely couldn't get too far away."

"Once we destroy this insect nest, it will naturally not be able to escape."

Lin Feng nodded, and waited until the swarm of red beetles went far away before pulling the trigger.

First use magnetic storm bombs to cover a large area and electrocute the dead creatures' nests, then switch to armor-piercing cannons to blow the hatching meat tower and the entire cave into pieces.

When the top collapsed, everything turned into nothingness.

While fighting and retreating, Lin Feng remembered what he had planned to ask before, so he asked the person behind him:

"Oh, right? Why are second-level peak tiger-spine insects so rare? I've killed so many second-level tiger-spine insects, but this is the first time I've encountered a peak one."

At this time, Ling Yi had already walked to the huge tiger spine worm corpse, exploring and observing its structure. When he heard Lin Feng's question, he looked as if it was a matter of course:
"Nonsense, this is a terrifying thing that can only be bred by a Stage 3 middle Queen Mother..."

"It's the same as the low-level black-spine insects, but the probability is higher. About three or four thousand second-level tiger-spine insects will give birth to a second-level peak tiger-spine insect."

"Once the tiger spine worms enter this stage, they will no longer obey the control of the queen mother, but instead follow the biological instincts in their genes, leave their swarm, and go to the end of the world thousands of meters underground to participate in a life-and-death struggle and a gamble of fate."

"Once you succeed and comprehend the inheritance of the spinal worm race, you will be able to become a rare third-level king spinal worm!"

"As the number of third-stage mid-stage queen mothers is increasing day by day, the number of king spinal worms currently undergoing metamorphosis has already reached a considerable size..."

"By then, as long as any queen mother on Blue Star dies at the hands of humans and has her powerful life energy taken away, the final transformation process will be activated, and the third-order king spiny worms that are born will also step onto the surface battlefield to help the queen mother and defeat any third-order enemies."

After hearing the detailed introduction of Lingyi, Lin Feng couldn't help but think about how powerful the third-order king spiny worm would be.

After all, it is only a lv29 tiger spine insect, which can easily kill dozens of second-level awakeners. Once it is promoted to a high-level king insect, it will be at the same level as the mother queen...

I'm afraid it will become the most difficult Zerg to deal with.

At this time, Ling Yi had obtained the genetic information of the second-level peak tiger spine worm. Looking at Lin Feng who was in a trance, he showed a subtle smile and said lightly:
"Don't think too much, your target is the high-level queen mother."

"In fact, as the commander of the insect swarm, the Queen Mother's own combat power can only be ranked at the bottom among all the high-level king insects. After all, her state of mind ability is not of the attack type."

"Otherwise, we would not have chosen this blue planet as the incubation site for the fourth-order queen mother. With your human strength, you are far from threatening the queen mother's growth."

"We will have enough time and resources to complete this global qualifying tournament..."

Lin Feng: "..."

"Okay, let's go, we have to start work here too."

Long Yi hummed, walked a few steps back and left a message:
"Also, the mother nest that was originally equipped with the second-level giant jaw has stopped working. It should have a lot to do with the biological furnace you destroyed. So in terms of materials, the only one is this second-level peak tiger spine worm."

"Do you need me to control the Scarlet Beetle and take it out?"

Lin Feng thought for a few seconds and shook his head:

"Forget it, I have other uses."

Lingyi did not stay any longer and turned away.

She had to guard those insect eggs and make sure they weren't attacked by the node mother.

Lin Feng leaned over and touched the tiger spine worm corpse, and the identification results appeared in front of him:
"Tiger Spine Worm lv29——Death State"

"It has the property of being as solid as a rock. All the carapaces on its body can be used as second-level orange materials. It has an integrated structure. After absorbing all of it, it can gain additional bonuses."

"Note: The whole is equivalent to 20 pairs of orange jaws."

Seeing the identification result, Lin Feng was immediately delighted, and then he absorbed it into the level 24 Flying Tiger Armor on his body.

Previously, due to the shortage of second-stage giant jaws and the absolute defensive use of the Flying Tiger Armor, Lin Feng had never upgraded it on a large scale.

Nowadays, this opportunity is rare and we can also use local materials.

Naturally, we can't let it go.

Especially after experiencing two trips to the insect nest, in addition to the thrills and excitement, Lin Feng naturally also felt the tactical shortcomings caused by insufficient armor on his body.

Especially in the future, when killing a high-level queen mother, more dangers and challenges will be faced, and the upgrade requirements for the Flying Tiger Armor are obviously greater than those for the Land Cruiser battleships responsible for long-range support.

Moreover, Lin Feng also needs to upgrade the battleship equipment to continue charging his genetic radiation skills.

As the orange light covered the entire insect corpse, the next moment, its half-meter thick solid outer armor was stored in the lv24 Flying Tiger Armor.

After activating the Flying Tiger Armor upgrade, Lin Feng raised the electromagnetic cannon in his hand and fired wildly at the dark cave behind him.

Boom! Boom!
The cave roof collapsed, bringing down the shattered biological nest, turning the entire nest into ruins.

Until the group arrived at the entrance of the wormhole...

Lin Feng has destroyed the last biological nest.

A reminder flashed before my eyes:

"Congratulations on successfully destroying a biological nest!"

"Kill the mutant mother - the node symbiote"

"Obtained ten times of second-stage upgrade energy..."

"Receive the gift from the node symbiote: Zerg spiritual energy"
