Chapter 145: First Exploration of the Forbidden Zone

Xiaofeng Mountain.

At this time, it was really quiet here, and there was not even a single insect in the surrounding woods.

One kilometer away from Xiaofeng Mountain, a blockade has been formed here, and mutant creatures are patrolling here.

Especially the mutant red fire ants and mutant bumblebees, which are the most important patrol forces.

Because their number is large enough, after discovering the other mutant creatures, they can immediately notify the queen bee or queen ant in a special way, and then Ye Feng will know to send the other mutant creatures to solve them.

At this time, this blockade is still expanding outward.

But the further the blockade goes out, the more places need to be defended. According to Ye Feng's estimation, when this blockade extends to 5 kilometers, it will not be completely blocked.

This is why he was anxious to explore this restricted area as soon as he broke through.

At this time, on a flat ground one kilometer away from Xiaofeng Mountain, mutant king cobras, mutant goshawks, and the big yellow dog and mutant buffalo who just arrived gathered here.

At this time, a fruit basket woven with rattan was hung on the neck of the big yellow dog.

Sure enough, there were 10 life fruits, half big and half small.

The big life fruit was condensed by Ye Feng using 1000 points of spiritual energy and biological energy. The vitality contained in it can quickly recover a seriously injured third-level mutant creature.

He temporarily named it the third-level life fruit.

As for the two small ones, Ye Feng used 300 points of spiritual energy and biological energy to condense them. The vitality contained in them can quickly recover a second-level mutant creature.

"I hope my idea can come true."

At this time, Ye Feng was possessed by the mutant buffalo. As he gave the order, a second-level mutant buffalo slowly walked out.

He was unwilling to use his contracted animals to try such dangerous things as exploring the restricted area, so their subordinates were undoubtedly the best experimental subjects.

Among all animals, the mutant buffalo is definitely one of the best in terms of defense strength. Among the same level, the only ones with stronger defense than them are white rhinoceros, hippopotamus and elephants.

But these mutant creatures brought out from the zoo are very precious, and Ye Feng certainly doesn't want to use them as cannon fodder.

As the mutant buffalo came out, Ye Feng thought about it and took out the third-level life fruit for safety reasons and threw it to the other party.

The second-level mutant buffalo got the signal and swallowed the life fruit in one gulp.

As the life fruit went down, the breath of the mutant buffalo became stronger.

Then, under Ye Feng's command, the second-level mutant buffalo began to approach the restricted area, and the mutant king cobra and mutant goshawk also followed immediately, so that Ye Feng could switch to the possession state at any time and observe the situation inside.

When the second-level mutant buffalo approached the range of 300 meters of Xiaofeng Mountain, it began to hesitate and refused to move forward.

Obviously, with the second-level mutant buffalo's perception of danger, it has already noticed that there is a great danger ahead.

The subordinates of these contracted animals are actually very loyal. They surrendered because of the powerful deterrence of their own kind.

It was fine at ordinary times, but when it was really in danger of life, how could it still listen to orders.

But at this time, Ye Feng could not let it go. The third-order mutant buffalo staring at the side suddenly mooed.

At the same time, the mutant king cobra, the mutant goshawk and the big yellow dog burst out deterrence together and locked the second-order mutant buffalo.

Feeling the fatal threat coming from behind, the mutant buffalo no longer hesitated, stomped on the ground and rushed directly into the restricted area.

Almost in an instant, the strange energy in the restricted area enveloped the mutant buffalo.

That kind of strange energy seemed to have a very terrifying corrosiveness.

The surface of the mutant buffalo's skin instantly ulcerated, and its breath began to decline.

But at this time, a vitality surged out of its body, and began to quickly repair the ulcerated skin on the surface of the body, and the declining breath of the mutant buffalo also stabilized instantly.

Seeing this scene, Ye Feng was happy.

Sure enough, the power of life can offset that kind of strange energy.

In this case, he really has the foundation to explore the restricted area.

Of course, it is only the foundation. Ye Feng does not think that the danger in the restricted area is only this strange energy.

Moreover, the life force in the mutant buffalo is limited, and it is impossible to help him recover all the time, so if he really wants to explore the restricted area, all these factors must be taken into consideration.

Next, Ye Feng let the mutant buffalo stay at the edge of the restricted area. The first thing he wanted to test was how long the third-level life fruit could allow the mutant buffalo to stay in it.

It didn't take long for Ye Feng to get the answer he wanted.

Ten minutes!

After only ten minutes, the life force in the mutant buffalo was exhausted, and its skin was festering rapidly.

At this time, Ye Feng didn't need to give orders, and the mutant buffalo rushed out frantically.

Because it stayed at the edge all the time, it escaped successfully, but even so, half of its skin had festering and pus.

Ye Feng was not stingy and directly threw a second-level life fruit to the other party, allowing it to recover quickly.

"This is equivalent to staying in there for 10 minutes, which requires consuming 1,000 points of spiritual energy to resist. Although the consumption is a bit exaggerated, it is still within my tolerance range."

Ye Feng thought quickly in his mind, but he did not act rashly, but conducted the next round of tests.

Next, he would conduct a set of comparative tests.

He directly called another second-level mutant buffalo and a second-level mutant sparrow.

Let them take the second-level life fruit, and then enter the restricted area together.

By comparing the two, he can know whether his own defense has a resistance to these strange energies.

Soon the mutant buffalo and the mutant sparrow were driven in.

The second-level life fruit contains limited life force, so this time the mutant buffalo only lasted for 3 minutes and escaped from the restricted area.

This was within Ye Feng's expectations.

But the mutant sparrow, which was weaker, was still in it.

And it was not until the 9th minute that the life force in the opponent's body was exhausted and escaped.

This scene made Ye Feng a little confused, and he didn't understand what was going on at all.

"The weaker the defense, the longer the resistance time?"

This was not reasonable at all, and Ye Feng always felt that something was wrong.

He closed his eyes and began to recall.

After possessing mental power, Ye Feng's memory was greatly enhanced. What happened just now flashed through his mind like a slide show.

After a moment, Ye Feng opened his eyes, his eyes bright.

Then he repeated the test again.

This time, when the second-level mutant buffalo and mutant sparrow entered, Ye Feng switched the possession state to the mutant goshawk.

Every detail of the mutant buffalo and mutant sparrow being eroded by the weird energy was clearly recorded in his eyes.

With his vision greatly enhanced, Ye Feng could clearly find that the speed of skin ulceration on the mutant sparrow was almost twice as fast as that of the mutant buffalo.

This was the same as his guess. The stronger the defense of the mutant creature, the stronger its resistance to this weird energy.

The reason why the mutant sparrow can persist longer than the mutant buffalo is entirely because it is small in size and is exposed to less weird energy.

If the two are of the same size, the mutant sparrow will definitely be the first to fail.

And such a discovery is naturally useful for Ye Feng.

Originally, according to Ye Feng's plan, he was going to send the mutant buffalo with the strongest defense to explore the restricted area.

But now he feels that it would be better to replace it with a big yellow dog.

After all, the big yellow dog is small in size and should be able to hold on for a longer time. In addition, it is the fastest among all the subordinates. Even if it really encounters danger, the probability of escaping is greater.

Moreover, the dog's sense of smell, vision, and hearing are all better than the mutant buffalo, which naturally makes it easier for Ye Feng to search in.

After making a plan, Ye Feng quickly took action.

He asked the big yellow dog to eat a third-level life fruit first, and the dog also held one in its mouth, just in case.

After doing all this, Ye Feng switched the possession state to the big yellow dog, and his body jumped into the restricted area.

Soon he felt that the restricted area was full of strange energy.

When he came in, these strange energies immediately attached to him. It was extremely corrosive, just like strong sulfuric acid.

Even though the big yellow dog has reached the third level, its defense is not strong, and its skin began to fester instantly.

This is the first time that Ye Feng has come into direct contact with this kind of energy. "Is this strange energy? It's so corrosive, I'll just call it corrosive energy."

At this time, as the body is injured, the life force contained in the body will automatically flow to the wound for repair.

Ye Feng did not move, but stood still and felt it for a moment. Soon he deduced that with the corrosion rate of these energies, the life force in his body can last at least half an hour.

If the life fruit in his mouth is counted, he can stay in this restricted area for a full hour.

"That's great, then I don't have to rush. I hope this exploration can gain some useful information." Ye Feng muttered while controlling the big yellow dog to move forward.

But he stopped after only 100 meters.

"Why has the concentration of corrosive energy increased? And it has increased by about 10% in such a short distance."

Ye Feng continued to move forward and found that as he continued to move forward, the concentration of corrosive energy was also increasing rapidly.

This made him secretly shocked. It is entirely conceivable that if he reached the central area of ​​this restricted area, the concentration of this corrosive energy would be so high.

Ye Feng was thinking about these things while moving forward, but at this time, his pace could not help but slow down.

He was really afraid that he would break into a place with extremely high corrosive energy and cause the big yellow dog to die instantly.

After all, such a weird place has appeared, and it is normal for some incomprehensible dangerous situations to appear in it.

Soon Ye Feng arrived at the foot of Xiaofeng Mountain.

Then with some trepidation, he began to climb the mountain.

But after just a short distance, he stopped again.

"Why did the concentration of this corrosive energy decrease instead of increasing?"

Ye Feng walked back with some doubts and found that he was not wrong, it was indeed the case.

Then, he quickly went up the mountain.

It was soon discovered that the concentration of corrosive energy decreased as one got closer to the top of the mountain.

After thinking for a while, Ye Feng returned to the foot of the mountain.

This time he did not climb the mountain, but used his forelimbs to dig the soil frantically.

Although the big yellow dog is not good at strength, as a third-level mutant creature, its strength is at least two tons. Every time its feet dig, it can bring out a large piece of soil.

A dog hole quickly formed, and Ye Feng did not stop. The dog hole continued to extend inside.

"Just as I thought, the concentration of spiritual energy has indeed increased."

"In other words, the source of this corrosive energy is inside Xiaofeng Mountain... Hey, that's not right!"

When a huge rock appeared in front of him, Ye Feng slightly changed the direction of digging, and immediately found that as he dug down, the concentration of spiritual energy increased sharply.

After a little comparison, Ye Feng confirmed that the source of the corrosive energy was below the ground.

He immediately changed the direction of digging and went underground.

In a blink of an eye, 10 minutes passed, and Ye Feng had dug 100 meters underground.

The corrosive energy here is 10 times more concentrated than the outer area.

The big yellow dog had already taken the second life fruit, and had consumed most of it.

"No, I can hold on for another 3 minutes at most, but I don't know how far I am from the source." Finally, Ye Feng sighed and began to control the big yellow dog to return.

However, this trip was not completely fruitless. At least he had a deeper understanding of these corrosive energies.

And the next step was how to deal with it.

But in this situation, it was obvious that he could not solve it with his personal ability alone.

So he had planned to inform the military of the news here in the restricted area.

...

At this time, the sky had completely darkened.

Although it was only one day, in the entire Yangcheng City, with all the construction forces mobilized, a full 30 kilometers of defensive walls had been built and the foundation was completed.

Laying the foundation is the most difficult. As long as this step is completed, the subsequent construction is just to fill concrete and boulders according to the drawings.

At this time, Zhang Ji was escorting a full 200 mud trucks back with the men of the Sixth Regiment.

"Secretary Cao, this is the last batch of boulders shipped today, enough for you to rush to work tonight." Zhang Ji came to Cao Guangzhi and said.

Secretary Cao Guangzhi is one of the persons in charge of the construction of the defensive wall. His main job is to coordinate various departments and follow up on the purchase of various materials.

"Thank you for your hard work, but there is still a little shortage of boulders."

"The amount mined back needs to be increased by at least 20% on this basis to fill this gap. Can you rush to dig more tomorrow?" Cao Guangzhi asked quickly while registering.
