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

Chapter 287: Moving Forward, What I Saw and Heard, He Jie
Considering that this trip was into the rear area and there was basically no possibility of danger, Lin Feng left the colonial mecha, ion laser cannon and hunter king chainsaw sword as a set in the returning team.

The Salvation Army will set out early tomorrow morning and return to the Jincheng base in the south.

During this thousand-kilometer journey, if they encounter an attack by a mid-stage third-order Queen Mother, they can rely on the sentry guard mode of the colonial mecha to safely survive the crisis.

Of course, with the support of the ion laser cannon, the electromagnetic cannon replicas in everyone's hands are enough to deal with the attack of countless insect hordes.

Even an ordinary mid-stage third-level queen mother can gain a chance to kill through the cooperation of the five third-level beings in the team.

On the contrary, Lin Feng and Long Yi are not suitable to carry these large equipment because they are too conspicuous.

In order to obtain the most authentic information this time, Lin Feng plans to sneak into the laboratory first, find He Jie and Ding Chenghai themselves, and make plans after listening to their introduction.

Instead of notifying federal senior officials with great fanfare, give them time to whitewash and revise.

After arranging everyone's itinerary, Lin Feng took Long Yi to stand on the mountain and waved goodbye to everyone.

At this time, Long Yi has been promoted to the initial stage of the third stage:
"Longyi, lv33/39, Zerg Queen's clone"

"HP 3k, PH 3k, SP 3.5k"

"Artistic Concept - Infinite Reproduction (Cannot be used when the spiritual attribute value is less than 1000)"

"Unlimited reproductive evolution capabilities: mind control, parasitism, gene control..."

She is level 33, with a spiritual attribute value of 3,500. If combined with the attributes of the Queen Mother, she is enough to rival a perfect Queen Mother at the mid-stage of the third level.

It’s a pity that this time when going to the Northwest Safety Zone, some things need to be consulted and referred to by Longyi’s opinion. Otherwise, if she led the team back, Shen Jie and others would undoubtedly be much more relaxed.

"How do we go? Do we need to summon the green-winged insect?"

Longyi asked.

She was wearing a level 30 golden battle armor that was integrated with the membrane wings of a second-order wind-wing insect. She could fly at a speed of Mach for twenty minutes and reach a distance of four hundred kilometers.

However, the final destination of this trip is the Lancheng University Research Institute in the heart of the northwest.

Starting from the vicinity of the federal capital, one has to cross four states to the west, covering a distance of 1,400 kilometers.

The flying mode of the golden armor cannot reach the destination quickly in a short period of time and requires a long cooling time.

So Lingyi suggested riding on the green-winged insects and slowing down the advance. They only needed two more transport insects to carry the organic nutrient solution...

It can reach its destination within two hours at a speed of 720 meters per second, or kilometers per hour.

Although the flying speed is fast when using the golden armor, one needs to wait for an hour of cooling time during the process, which is not worth it.

Lin Feng nodded and agreed.

The golden armor's flight mode is not very suitable for traveling, it is more important to save it for fighting.

Moreover, they are now Lin Feng and the other two's greatest reliance for survival, so they should not waste the flying function easily.

Lingyi then snapped his fingers, and four first-stage late-stage green-winged insects flew over from the top of the main peak of the Yunxialing Mountains. They were seven or eight meters tall, with a wingspan of nearly twenty meters.

Enough to carry Lin Feng who weighs nearly a ton.

In addition to the two passengers, there was also the transport insect responsible for logistics supply as mentioned by Longyi. It had a huge tail segment and, like a bee, its butt was filled with a large amount of organic nutrient solution.

As the two climbed onto the insect's back and grasped the thorns on both sides, the dragonfly gave an order, and the four green-winged insects crawling in the mountains waved their long membranous wings on both sides...

The high frequency flapping creates a strong airflow.

Slowly rose into the air and flew to the northwest.

The maximum activity distance of a normal swarm of blue-winged insects will not exceed the range of influence of the queen's mental power.

For example, the early stage mother queen can cover an area of ​​20 to 30 kilometers, while the middle stage mother queen can cover an area of ​​50 to 100 kilometers...

Therefore, most of the human air defense lines are deployed in the command centers behind the front line.

In the rear areas hundreds of kilometers away from the front lines, even guard posts were rarely deployed.

This also has a lot to do with the Zerg organizational structure.

After all, in order to be obedient and maintain combat effectiveness, they can only make trade-offs in terms of intelligence, which leads to the combat effectiveness of the Zerg swarm plummeting instantly after leaving the control and command of the Queen Mother.

To the highly organized human army, the threat posed by the ownerless insect swarm is actually very low.

So Lin Feng and the other person rode on the green-winged insect and crossed the Taihang Mountains where Yunxialing is located without any obstruction.

Entering the rear, Jinzhou is a major coal mining state in the federation, supplying more than half of the country's coal consumption.

The steel group set up many coal bases here, using railway transportation to provide large quantities of coal to the major steel-making cities in the rear.

Today, several large cities in the area are shrouded in the doomsday shadow of the Zerg invasion and have become deserted and abandoned cities, with a sense of depression and desolation everywhere.

Most of the remaining thousands or tens of thousands who did not leave were elderly people with limited mobility who barely made a living by growing vegetables in the suburbs.

Lin Feng did not enter the urban area for fear of disturbing them and causing unnecessary panic. He observed from afar several mining industrial areas where there were still lights.

Tens of thousands of people live here, stick to their posts, and continue to supply industrial power to the rear.

Later, a group of two people and four insects came to Qinzhou, the center of the ancient federation.

There are ancient cities everywhere, as well as many areas that were once polluted by heavy industry.

After experiencing the Great Depression, the company has regained its vitality and started operating at full capacity thanks to the strong demand from the war on the front lines.

Several large base cities in the rear safety zone are located in Qinzhou.

According to Qin Hu, there are six large base cities with a population of tens of millions, four in the south and two in the north. Unfortunately, the Federation still has full control over only the two big cities in the north.

The four cities bordering the southern states have already formed a semi-independent state under the guidance of their own awakened people. They are the kind that obey orders but not instructions.

Among them is the Iron and Steel Alliance Group's industrial base, which is located in the south and southeast corner of Qinzhou, with a total of two bases. They are specially designed to process thousands of tons of coal shipped from Jinzhou, and at the same time transport coking coal, coke, and electricity to the non-ferrous smelting base in Xiangzhou in the south.

Because Qinzhou is located south of the Changhe River and its terrain is dominated by loess mountains, in order not to expose its own existence, Lin Feng asked Long Yi to control the green-winged insect and lower its flight altitude.

Try to sneak among the barren and dim mountains towards Longzhou, your destination.

Soon, the two entered the territory of Longzhou. There were not many survivors gathered here, and most of the refugees stayed in the large base city of Qinzhou.

At least there are abundant resources there, and you can earn a living by working in factories, but the environment in Longzhou is too harsh, and there is not even a large base city with a population of tens of millions.

The only large city, Lancheng, the provincial capital, has a population of only a few million. Like Jincheng in the south, it is built around a long river in the north.

In the harsh environment with dust everywhere and smog covering the sky, Lancheng can barely guarantee water supply in the hot summer.

Lin Feng took out a map provided by Qin Hu and quickly found the university town in the center of the city. His mother He Yiwen's research center was in a research building in the university town, but Lin Feng was not sure of the exact location.

But as long as the approximate direction is determined, through telepathy and Long Yi's mental scan, the specific location of He Jie and Ding Chenghai can be quickly found.

"We're finally here. Let's go and find a place to hide them first."

Lin Feng spoke slowly, and the two of them landed on a gravel wasteland outside the city.

Before the sun completely set, they found a hillock and hid the four green-winged insects there.

After instructing them to drink the organic nutrient solution and not run out without permission, Longyi followed Lin Feng's steps and walked towards the only big city in the wasteland in front of them.

The two of them walked briskly, maintaining a steady pace of dozens of meters per step, and in a few moments they arrived at the outskirts of Lancheng.

Although this place is called a suburb, it is already filled with some of the survivors who have been diverted here. Those who have fled here basically have to rely on the help of the War Management Committee to barely survive.

However, Lin Feng saw many people among them who looked numb but had good strength.

Their physical attributes are generally high, and some even reach the level of sixth-level enhanced humans, but their bodies are very weak, and their health and mental attributes are far lower than normal humans.

Just as Lin Feng was puzzled, Ling Yi beside him spoke directly and explained softly:
"They have done experiments, probably using the special cells of other awakened humans, hoping to improve the overall evolution level of the tribe."

“It is equivalent to developing the most universal and adaptable evolutionary medicine from a large number of experimental samples.”

"So these people are used as waste and naturally become the victims behind the progress of the ethnic group..."

Lin Feng did not nod and remained silent.

Ling patted his shoulder:

"Now is the time for the survival of mankind. Don't worry so much. If we can improve the basic strength of all of us to the stage of enhanced humans, it will undoubtedly be a huge improvement for the overall improvement of mankind."

"After all, when fully armed, enhanced humans can definitely compete with the first-order black-spine insects of the Zerg."

"The improvement of the overall evolution degree can also expand the foundation for the birth of awakened people from the originally large group of ordinary people, thereby increasing the number of awakened people."

"Not all of these people have been experimented on, so they are probably voluntary."

"It's a good deal to exchange experiments for material compensation."

Lin Feng nodded and stopped thinking about these things. He took Long Yi and turned into a shadow, disappearing into the refugee gathering area outside the city.

Soon we saw a large biological research institute in the city, which was still brightly lit at dusk. This should be the main center of the Federal Institute of Biology.

According to Lin Feng's telepathy, there are many weak but powerful beings in these buildings and underground laboratories.

They all have the strength level of the middle and late second stage.

The brightness of some light sources is even comparable to that of a peak-level second-order genetic warrior, so their strength should not be underestimated.

At this moment, Lin Feng also thought of the artificial superman project of the Federal Biological Research Institute that he had learned from Ling Shuyan when he was still in Jincheng Base.

Taking advantage of the excellent performance of teenagers and children in the fusion of superpower genes, we help them awaken and implant multiple superpower tissue cells...

This allows it to release a variety of different abilities in battle.

The only problem with doing this is that the load is too heavy, which will seriously consume and overdraw the vitality of the experimenters, shortening their lifespan while leaving them in a semi-weak state...

The combat endurance is greatly reduced.

However, this time he came to Lancheng in the northwest not to witness the effect of the federation's roundabout way to save the country, but to find clues to his parents' past.

So Lin Feng took the curious Lingyi away from the brightly lit biological industry area.

Arriving outside the university town and confirming the location of the research institute building, the two entered and saw that only a few laboratories had lights on.

Lin Feng used his telepathy to take a precise look and confirmed a laboratory, which was most likely where He Jie and the other were.

Ling Yi, who was standing by, also used mental means to clean the place inside and out, and then analyzed the pheromones in the air to confirm its location just like Lin Feng.

Moreover, the targets chosen by both parties are surprisingly consistent.

After smiling at each other, the two continued to sneak.

With Longyi around, all he had to do was glance at a nearby guard and he would immediately fall unconscious. Under the blow of the mental hammer, he would instantly fall into a baby-like sleep.

This is the benefit of mastering spiritual means, being able to sneak into various places silently. The reason why the Zerg mother was able to act as a spy and lurk in the human army was obviously because of her outstanding spiritual power.

After breaking through these peak first-level guarding forces, the ghostly figures of the two quickly approached the laboratory where He Jie and Ding Chenghai were.

Lin Feng looked at the introduction board outside the laboratory, which had his mother He Yiwen's ID photo, as well as her professional title, background, and research direction, and he couldn't help feeling deeply moved.

As her son, I haven't been here once in all these years since He Yiwen was transferred here to do research.

He raised his hand and placed it on the door handle, applying slight force and directly broke the internal lock core.

After pushing open the door, Ding Chenghai was seen holding a long knife made from the giant jaws of a tiger-backed worm, protecting a woman in a white coat behind him.

It was not until Lin Feng and the other man revealed their appearance under the dim light that Ding Chenghai's tense nerves finally relaxed.

Then he was so excited that he was shaking all over, and he couldn't even smile or speak clearly:

"Lin...Lin Feng?"

"Good boy, why are you here!?"

Lin Feng shrugged, opened his arms, and hugged Ding Chenghai, who looked haggard.

In March after the outbreak of the apocalypse, the two, once familiar friends, met again after experiencing so many twists and turns, and they were filled with emotion.

"Sit down and talk."

Lin Feng patted Ding Chenghai on the shoulder, took out a few bottles of organic nutrient solution from his backpack and handed them to Ding Chenghai.

After the latter took a sip, his eyes suddenly lit up.

He happily handed the remaining bottles to the woman behind him.

Lin Feng turned his head and looked at the familiar old friend in front of him with a serious expression.

The other person looks somewhat similar to his mother He Yiwen and is a relative on his mother's side.

Lin Feng didn't have a very deep impression of her, and the two of them didn't communicate much. After all, the world of academic masters was very different from that of ordinary people like himself.

Now that they met again, Lin Feng coughed lightly:
"Long time no see, cousin..."
