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

Chapter 132: Hive Battle, Tiger Tooth Chainsaw Sword
Hearing several gunshots coming from the darkness in the corridor of the city wall, Lin Feng and Shen Jie couldn't help but quicken their pace.

Run quickly towards the source of the sound.

While running, Lin Feng activated his telepathy skill to detect the Zerg hidden in the target direction.

Soon, in a wormhole 800 meters away from the two of them, signal lights of a second-order awakener and several first-order late-stage fully awakeners appeared.

Unlike the Zerg, due to the size difference, although the human awakeners have the same light spot brightness as the Zerg of the same level, the size of the light source displayed is only one-third of that of the Zerg, or even smaller.

This is also the main basis for Lin Feng to distinguish between the awakened and the insect swarm when analyzing the exploration results.

Presumably, these awakened ones who went deep into the wormhole are the elite team led by Qin Hu.

As Lin Feng and the other person got closer and closer to the site of the battle, their telepathy detected that several second-order Zerg had appeared deeper in the wormhole and were fighting fiercely with Qin Hu and the others.

Lin Feng, who was fully armed, raised the electromagnetic cannon in his hand and asked Shen Jie, who had entered the black warrior state, to step back and wait for the opportunity to move.

His Wing Tiger's frenzy state can only last about five minutes and has to be used at critical moments. Moreover, Shen Jie's melee ability is stronger than his, especially inside the wormhole. If too many armor-piercing bombs and magnetic storm bombs are fired, it will easily cause the cave to collapse and bury everyone.

Seeing that the wormhole entrance from which the sound came had appeared not far away, Lin Feng whispered a reminder:
"Wait, you will be in charge of the left and right guards and take care of the rear. The Zerg attacking from the front will be left to me."

Shen Jie nodded. In the black warrior form, the two-meter-long black and gray arm blade was shining with cold light. After being transformed by Zhang Liying, the black armor that appeared on his body could be combined with the red armor, which was equivalent to double the armor.

It is enough to withstand the powerful attack of the tiger-backed worm.

It's equivalent to having an extra life.

Ten seconds later, the two successfully passed through the obstructed defense corridor and arrived under a main castle.

At the bottom of the main fort, the warehouse originally used to store weapons and supplies was hollowed out by the Zerg, and a deep pit with a diameter of 20 meters appeared in front of the two.

Fortunately, the entrance of the cave was slanted downward, so they didn't have to jump straight into it. The two looked at each other, and then walked into the bottomless cave one after the other.

The entire wormhole was filled with that familiar strange smell, which was stronger than that in the defense corridor. Fortunately, the underground nest dug by the red beetles had a very complete ventilation system. It could connect to the surface air and circulate it into the cave, ensuring that there was still oxygen a hundred meters underground.

As carbon-based flesh-and-blood life forms, Zerg also require redox reactions to decompose nutrients in their bodies as the basis for the continuation of their life activities.

After being transformed by the biological factory, low-level Zerg have adapted to absorbing oxygen as a way of survival.

Therefore, ventilation of insect nests is extremely important.

Lin Feng and the other two can also rely on the powerful sensory organs of second-level awakeners to detect the direction of weak airflow and avoid getting lost after going deep into the bottom of the insect nest.

Unfortunately, Lin Feng's telepathic skills cannot detect the structure of dead objects, and can only show the location of living things.

Fortunately, the continuous explosions coming from deep in the cave allowed the two to successfully find Qin Hu and others.

As the two sides approached, Lin Feng unexpectedly heard some strange noises, like the sound of machinery operating in a factory, crackling and echoing in the cave.

Perhaps it was the Pulse Scorpion's electromagnetic pulse cannon that reduced its power and was attacking Qin Hu and others.

After walking more than 200 meters in the dim wormhole, the two finally saw a light coming from the distance.

Qin Hu and his men were seen wearing Zerg exoskeleton armor similar to the Red Black Armor, and holding a heavy sword-like melee weapon in their hands.

But the black and yellow weapons made a high-frequency buzzing vibration sound. When they were wielded flexibly in the hands of the awakened ones and split the attacking second-order tiger-spine worms, they directly rubbed out the sizzling sound that Lin Feng heard.

The giant sword collided with the giant jaws of the tiger-backed worm, splashing out dazzling sparks.

With the help of the searchlights they were equipped with, in the dim light, Lin Feng saw that those weapons that looked like heavy swords were actually a two-meter-long electric chainsaw!
With the help of the madly rotating motor, the saw teeth began to cut the giant jaws of the tiger spine worm.

Especially when the awakened ones raised their chainsaw swords to block the tiger-backed worm from raising its upper jaw to bite, the rotating saw teeth could directly cut off the giant jaw in just two or three seconds.

Such a powerful display made Lin Feng's eyes light up and he couldn't take his eyes off it.

Soon, Lin Feng walked behind the group of awakened people.

He raised his gun and aimed at a late-stage second-stage lv27 tiger-spine worm that was about to pounce in front of the crowd.

As he pulled the trigger, under the headshot lock of the Death Eye attribute, the damage of the armor-piercing bullet was as high as 900 points, hitting the tiger-back worm's torso behind its jaw directly, and then exploded inside its body.

I saw the entire second-level insect body explode!
The ten-centimeter-thick armor was shattered into pieces, and the body parts flew everywhere.

But because of this, the power of the armor-piercing shells was absorbed by the tiger-back worms and did not have much impact on the nearby caves.

With the death of the only late-stage second-stage tiger-spine worm, the Zerg's offensive was gradually suppressed, and the elite team led by Qin Hu fought and retreated.

He used the chainsaw sword in his hand to split a second-stage tiger spine worm in its mouth, then turned and walked in front of Lin Feng, shouting:

"What are you doing here?"

Because of the chainsaw sword's attack, the noise of cutting was deafening and difficult to hear.

After Lin Feng barely understood, he also replied loudly:

"This could be a trap!"

"The new second-order Zerg will ambush you!"

Qin Hu shook his head. At this moment, the battle in front was nearing its end. Many awakened people in the late stage of the first stage successfully completed the first kill of the second-stage Zerg with the powerful chainsaw swords in their hands.

As long as you return to the second line of defense, you can enter the second-level deep awakening and become another second-level awakener.

Combined with the genetic modification surgery of the research institute, genetic warriors with strength comparable to the mid-second stage will all appear on the scene.

During this period, even Shen Jie used the shotgun in his hand to seriously injure a tiger-backed worm, and then used his two-meter-long arm blade to kill it, gaining energy for upgrading.

As the war ended, everyone retreated to the outer entrance of the cave to rest for a while.

Lin Feng and Qin Hu continued to communicate.

Through identification, Qin Hu has now reached level 22, which means that he has killed at least five second-level Zergs, but he has not entered the state of genetic assimilation. He probably relies on the extraordinary melee weapon in his hand.

Qin Hu took a deep breath and said excitedly:
"This is the first time that we humans have defeated a Zerg attack underground in a wormhole! But we didn't expect that the scale of the underground wormhole is even larger than we imagined!"

Pointing to the cave where everyone had just left:

"According to the data from the research institute, there should be a third-level insect nest there, which is about three or four square kilometers in size, equivalent to a commercial district."

"There are thousands of first-level black-backed insects and a dozen second-level tiger-backed insects living inside. After we went in, we drove away the low-level insects, but we were chased and intercepted by the tiger-backed insects. In the end, we retreated back to the insect tunnel while fighting."

"Fortunately, you took action. Otherwise, we would have suffered casualties when facing that second-stage late-stage tiger-spine worm."

Lin Feng shrugged. To be honest, after completing the upgrade of the lv2 electromagnetic cannon and himself, he was no longer willing to take action. No matter how many tiger-spine insects he killed, there would not be much benefit.

Moreover, being in the underground cave, it is impossible to bring back too many biological materials for fusion and upgrading. Unless you encounter new second-level Zerg, Pulse Scorpion, Tank Flame Armor, etc.

Facing the second-level tiger-spine worm, Lin Feng would rather give the upgrade opportunity to Shen Jie or other awakeners.

After all, second-level Zergs are still quite rare, and such close-range combat experience is also equally valuable.

It can allow the awakened ones to grow quickly.

After hearing Qin Hu's introduction, Lin Feng asked:
"So you are going to continue to stay in the wormhole and fight in order to complete the mission assigned by the institute?"

"Those new second-order Zergs are not that easy to deal with. Compared to the tiger-spine Zergs, they are more professional and specialized. Just like the difference between ordinary soldiers and snipers and rocket soldiers, they are extremely difficult to deal with."

Qin Hu nodded, took off his mask, lit a cigarette for himself, and took a deep breath:
"Yeah, but we have this!"

He raised the chainsaw sword in his hand, exhaled a puff of white smoke and continued:
"It is our mission and responsibility to understand and obtain intelligence on the new second-order Zerg, hand it over to the research institute, and then study how to deal with them."

"And victory in the war also requires this information. The capital has sent several teams of genetic warriors, but because they are facing so many queen mothers and the wormhole cave has a complex structure, no one has survived so far..."

"There is only one queen mother in Haicheng, and the number of new second-level Zergs it hatches is also small. This is one of the few excellent opportunities for us."

"Besides, this time, we have gained more than just these."

Qin Hu turned his head and took a look at the team member sitting behind him, the deputy captain of the team, a level 19 awakener.

He is also a genetic warrior. Lin Feng and Shen Jie can both smell the strange smell emanating from him and the hint of madness that flashes in his eyes.

The vice-captain interrupted:

"Hello, Sergeant Lin, I have heard of your great name for a long time."

"My name is Chen Shu. I was the former commander of the 98th Company and I am currently serving as Colonel Qin's deputy."

Chen Shu took out a bag of things from his backpack, showed it to Lin Feng, and then carefully put it back.

It was a medical biochemical PE sealed bag with a yellow skull warning sign printed on it. It contained some substance that emitted a faint green fluorescence, similar to the slime fungus that grew on rotten wood.

Chen Shu pushed his non-existent glasses away out of habit. He was probably a top student in the past. If it weren't for the invasion of the alien Zerg, he wouldn't have had to risk his life in the Zerg's heartland.

After showing it to everyone, Chen Shu introduced:
"This is some kind of luminous slime mold we found in the insect nest. It seems to be able to produce nutrients. I saw red beetles sucking it from afar."

"If we take it back for research, we might be able to uncover the basic life cycle of the Zerg. If we can find a way to destroy this luminous substance or its proliferation environment, we can cut off the survival foundation of the Zerg like cutting off the firewood from under the cauldron."

"Destroy their staple food."

"This is more meaningful than victory on the front battlefield."

Lin Feng nodded, this was also an idea.

Qin Hu finished smoking most of his cigarette and said with a smile:
"People with culture are different. We rough people can't compare to them."

Then he looked at Lin Feng with a serious expression:
"Do you want to go together? Or do you want to leave first? But with your joining, using long-range attack methods, I believe we can easily win against the new second-level Zerg..."

Lin Feng stared at the chainsaw sword in Qin Hu's hand and nodded.
"No problem, this is one of the reasons why I came here."

"There's something special about this weapon. Are the teeth on it made from the giant jaws of the tiger spine worm?"

Qin Hu smiled. He knew very well that Lin Feng was coveting this weapon. He stood up and swung the chainsaw while solemnly introducing it:
"This is called the Tiger Tooth Chainsaw Sword, and it is the latest individual weapon developed by the Weapon Research Institute. The sharp teeth are made from the giant jaws of the tiger spine insect, and the sword body is made of tungsten alloy. It is two meters and three meters long, the chainsaw is one meter and eighty meters long, and thirty-five centimeters wide. It weighs a terrifying eight hundred kilograms. If you don't have the late stage of the first order, and the physical strength is close to ten tons, you can't wield it for a long time."

"Of course, in your hands and mine, this chainsaw sword is just the right weight, or even a little lighter."

"The research institute is currently developing weapons that are more suitable for second-level awakeners."

Then Qin Hu took out three fist-sized tiger worm saw teeth from the backpack behind him and replaced the excessively worn teeth on the chainsaw sword.

"Yes, this is a modular design. Each sawtooth can be replaced individually, which is convenient for maintaining combat effectiveness. And the thirty kilograms of fuel fully loaded under the backpack is enough for it to be used for more than five hours..."

"With it here, any second-level Zerg that gets close will be cut to death by its tiger teeth!"

Lin Feng nodded, agreeing very much.

The tiger-spine worm's giant jaws, as the hardest organ of all second-order Zerg, do have the ability to break through all defenses after being made into serrations.

Especially under the gravity of the Tiger Tooth Chainsaw Sword itself, the power bonus of the awakener, and the repeated cutting of the teeth, even the Flying Tiger Armor would not be able to withstand it for long.

It’s a pity that to deal with the second-level tiger-spine worm, the saw teeth need to be replaced in time, but there is no time to replace them during the fierce close combat.

If it is treated as an item, bound into equipment, and then upgraded, perhaps this defect can be solved.

After witnessing the powerful force of the Tiger-tooth Chainsaw Sword, Lin Feng had already been tempted.

As Qin Hu fully displayed himself, the appraisal results appeared before his eyes:

「Tiger Tooth Chainsaw Sword lv24/29, orange quality」

「升级点3/10，耐久度：10/10，单锯伤害400」

"Note: After starting the chainsaw, it deals 2000 damage per second, causing effective damage. The durability decreases by one point every ten seconds. The damage decreases as the durability decreases. Replacing new teeth can restore the durability."

"Evaluation: This is a primitive and terrifying melee weapon, but it is surprisingly effective against the more brutal and cruel Zerg. It is the strongest shield in the world, so it can naturally become the sharpest spear. Use it with caution and pay attention to its durability."

After reading the appraisal given by the system, Lin Feng exclaimed, "Wow, the speed at which the wear is reduced is faster than driving without releasing the handbrake."

But thinking about it carefully, according to the reminder in the notes, it can be used normally for about 50 seconds at full status, and the damage per second is more than 1,000. During the battle, on average, it takes two seconds to kill a tiger spine insect...

In this case, a tiger-tooth chainsaw sword can kill at least twenty tiger-spine worms before it is almost scrapped.

In fact, it’s been pretty good.

Maximize the utilization value of the tiger spine worm's giant jaws.

The owner might be exhausted before killing twenty tiger-backed insects.

Qin Hu in front of him seemed to see that Lin Feng was moved, so he picked up the tiger-toothed chain saw sword in the hands of the adjutant beside him and handed it over:

"Try it, you'll definitely like it."

Lin Feng narrowed his eyes, but did not reach out his hand:
"What price?"
