Global Catastrophe: I Became the World Tree-Chapter 168 - 144 Exploring the Forbidden Zone_2

Ye Feng thought quickly, but he still did not act rashly, instead, he conducted the next round of tests.

Next, he planned to conduct a set of comparative tests.

He called over another Second Order Mutated Buffalo as well as one Second Order Mutated Sparrow.

He had them both ingest Second Order Life Fruit before entering the forbidden zone together.

By comparing the two, he would be able to know if his own defensive power had any resistance against this mysterious energy.

Soon enough, the Mutated Buffalo and the Mutated Sparrow were driven inside.

The Second Order Life Fruit contained limited Life Energy, so the Mutated Buffalo only lasted about 3 minutes before fleeing the forbidden zone.

This was within Ye Feng’s expectations.

However, the seemingly weaker Mutated Sparrow stayed behind.

And it wasn’t until the 9th minute that its Life Energy was entirely depleted, and it escaped.

This scene left Ye Feng somewhat baffled, completely unsure of what was going on.

"The weaker the defensive power, the longer the resistance time?"

This made no sense, and Ye Feng also had the feeling that something was amiss.

He closed his eyes and began to recall the events.

After obtaining spiritual power, Ye Feng’s memory had also greatly improved; the events that had just occurred flashed through his mind like a slideshow.

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

Then he repeated the same test.

This time, after the Second Order Mutated Buffalo and Mutated Sparrow went in, Ye Feng switched to Avatar Status on the Mutated Eagle.

Every detail of the two creatures being corroded by the mysterious energy was clearly observed by him.

With his significantly enhanced vision, Ye Feng could clearly see the Mutated Sparrow’s skin was decaying at nearly twice the speed of the Mutated Buffalo.

This confirmed his guess: Mutated Beings with stronger defensive power had stronger resistance to this type of mysterious energy.

The reason why the Mutated Sparrow could outlast the Mutated Buffalo was simply because of its smaller size, which meant it came into contact with less mysterious energy.

If the two were the same size, the Mutated Sparrow would definitely be the first to give out.

This discovery was naturally useful for Ye Feng.

According to his original plan, Ye Feng intended to send the Mutated Buffalo with the strongest defense power into the forbidden zone for exploration.

But now he felt it would be better to switch to Big Yellow Dog.

After all, Big Yellow Dog’s smaller size meant it could last longer, and besides, it was the fastest among his subordinates, so it would have an even greater chance of escaping in the event of danger.

Moreover, a dog’s sense of smell, vision, and hearing were all superior to that of a Mutated Buffalo, which would naturally make it more convenient for Ye Feng to conduct a search.

After setting the plan, Ye Feng quickly took action.

He let Big Yellow Dog eat one Third Order Life Fruit first, and kept another one in its mouth, just in case.

After completing all this, Ye Feng switched to Avatar Status on Big Yellow Dog, then swiftly entered the forbidden zone.

He soon felt the forbidden zone was filled with mysterious energy.

As soon as he entered, the mysterious energy immediately attached to him, possessing an extremely strong corrosiveness, much like sulfuric acid.

Even though Big Yellow Dog had reached Third Order, its weak defensive power meant its skin started decaying instantly.

Ye Feng was having his first direct encounter with this kind of energy, "So this is mysterious energy? Such strong corrosiveness, might as well call you Corrosive Energy."

Now, as injuries appeared on the body, the Life Energy contained within would automatically flow toward the wounds to heal them.

Ye Feng did not move, and stood still, quietly feeling it for a while; soon, he deduced that with the speed of the energy’s corrosion, the Life Energy within his body would last at least half an hour.

With the Life Fruit in his mouth accounted for, he could definitely stay in this forbidden zone for a full hour.

"Not bad, there’s no need to rush then, hopefully this exploration will yield some useful information," murmured Ye Feng as he controlled Big Yellow Dog to move forward.

But after just 100 meters, he stopped.

"Why has the concentration of corrosive energy increased? And at such a short distance too, it’s actually increased by around 10%."

As Ye Feng continued forward, he noticed that the concentration of corrosive energy was also drastically increasing.

This inevitably filled his heart with alarm; he could only imagine what the concentration of this corrosive energy would be like in the center of this forbidden zone.

While contemplating these issues, Ye Feng moved on, but at this moment, his pace involuntarily slowed down.

He was truly afraid that he might suddenly enter an area with exceptionally high corrosive energy, causing Big Yellow Dog to die in an instant.

After all, it was normal for some incomprehensible dangers to occur in such a mysterious place.

It wasn’t long before Ye Feng reached the foot of the Small Phoenix Mountain.

Then, with a somewhat uneasy heart, he began to climb.

But only a short distance into the ascent, he stopped again.

"Why has the concentration of corrosive energy decreased instead of increased?"

Ye Feng walked back somewhat confused, only to discover that his senses were not wrong – it was indeed so.

Then, he quickly scaled the mountain.

He soon discovered that as he got closer to the summit, the concentration of corrosive energy also became lower.

After pondering for a moment, Ye Feng returned to the foot of the mountain.

This time he didn’t climb but started frantically digging with his forelimbs.

Although Big Yellow Dog was not particularly strong in power, as a Third Order Mutated Creature, its strength had at least reached two tons. Every sweep of its paws unearthed large clumps of soil.

A dog hole swiftly formed, and Ye Feng did not stop; the hole continued to extend inward.

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

"That means the source of this corrosive energy is inside Small Phoenix Mountain... Wait, that’s not right!"

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

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

He immediately changed the direction of his digging, now heading underground.

In the blink of an eye, 10 minutes had passed, and Ye Feng had dug down to a depth of 100 meters.

The concentration of corrosive energy here was tenfold higher than in the outer areas.

Big Yellow Dog had already consumed the second Life Fruit, and most of it was already spent.

"I can’t keep this up, I can only hold on for at most another 3 minutes, but I have no idea how far I am from the source," Ye Feng sighed lightly and began to control Big Yellow Dog to return.

However, this trip wasn’t entirely fruitless; at least he had gained a much deeper understanding of these corrosive energies.

What came next was figuring out how to deal with them.

But under current circumstances, it was obviously impossible to solve this with his abilities alone.

That’s why he had already decided to inform the military about the situation in this restricted area.

...

By now, the sky had completely darkened.

Although only a day had passed, with all construction forces being utilized in Yang City, a 30-kilometer long defense wall had its foundations constructed.

Laying the foundations was the most difficult part. Once completed, the construction simply involved continuous pouring of concrete and placement of huge rocks according to the blueprint.

At this time, Zhang Ji was leading a group from Squad Six, escorting a total of 200 dump trucks back.

"Secretary Cao, this is the last batch of huge rocks brought in today; it should be enough for your overnight rush work," Zhang Ji said as he approached Cao Guangzhi.

Cao Guangzhi, as the Secretary-General, was one of the people responsible for the construction of the defense wall, primarily coordinating various departments and tracking material purchases.

"You’ve worked hard. However, we are still a bit short on the raw stone material."

"The amount mined needs to be increased by at least 20% on this basis to fill the gap. Can your team mine more tomorrow?" Cao Guangzhi asked rapidly while making the register.
