Global Catastrophe: I Became the World Tree

Within an hour after King Cobra broke through, sparrows, bats, and black crows all also broke through.

When they reached the late stage of the first level, their size had grown a lot, and their strength had increased significantly.

But the rat with the highest level did not break through to the second level as Ye Feng expected.

It seemed to have reached a critical point and was stuck there. Even the spiritual energy absorbed per hour was reduced from 3 points per hour to only 0.3 points per hour.

With such a small amount of spiritual energy absorbed, it is impossible to help the opponent continue to improve his strength.

"Isn't this the legendary bottleneck?" Ye Feng felt a little pain in his head.

He has never experienced this situation himself, because as long as there is an evolutionary point, he can break through.

"It should be possible to break through sooner or later, I just don't know how long it will take." Ye Feng recalled the rats in Asan Kingdom. Obviously, this was not the limit of mutated rats.

"But fortunately, it's just that the bottleneck of the big realm is stuck, and the small realm can still be broken through." Ye Feng muttered again.

If these mutant creatures couldn't break through even a small realm quickly, he would really have a headache.

Next, Ye Feng ignored these mutated creatures and began to indulge in adding points.

When the time came to early morning, he once again accumulated 40 evolution points and was able to break through again.

"Ding! Please choose the direction of strengthening."

Looking at the system panel, Ye Feng chose flexibility without much hesitation.

After 10 minutes, the breakthrough was successfully completed.

Host: Ye Feng (World Tree)

Tree height: 55 meters

Trunk width: 2.75 meters

Root length: 270 meters

Realm: late second level

Evolution points: 0/40 points

Special abilities: Devour, Capture

Aura value: 0/550 points

Bioenergy: 200/550 points

"It's been less than two days, and I didn't expect that I would become the tallest tree in this valley." Ye Feng was a little emotional, but more worried.

Because now he has become the most conspicuous presence in this valley.

And it is conceivable that as his strength increases, he will become more and more conspicuous.

"Forget it, don't think about it so much for now. You should focus more on things that are worth being happy about."

Ye Feng quickly shifted his attention to the roots of the tree.

As the flexibility was once again strengthened, Ye Feng found that the flexibility of his tree roots had once again been greatly improved, and it was no less than that of human fingers.

He can already control tree roots, make various movements at will, and can even use various tools and weapons flexibly.

Of course, in addition to these, the more intuitive point is that the movement and attack speed of tree roots are faster.

Uh-huh! Uh-huh! Uh-huh!

Following Ye Feng's thought, hundreds of tree roots burst out of the ground and attacked the mosquitoes flying in the air.

Previously, it would not have been so easy for him to attack these mosquitoes.

A single tree root will definitely be avoided, and the only way is to use a tree net, which is too inefficient.

But now, if the tree roots are whipped, 90% of these mosquitoes will not be able to react, and they will be hit directly and die instantly.

Even if he could react and dodge the blow from the first tree root, the second and third tree roots would immediately hit him.

At this moment, with Ye Feng as the center, mutant mosquitoes within a range of 270 meters fell like rain.

From now on, Ye Feng's territory will become a restricted area for these mutated mosquitoes.

During this process, Ye Feng originally wanted to get rid of the mutated flies as well.

But it is a pity that the fly was very flexible before the mutation, and now it has become even more terrifying after the mutation. His root whipping speed still cannot keep up, and he gave up after trying twice.

He is not in a hurry about any of these. With his current evolution speed, he will probably be able to deal with them in less than two days.

At the same time, as the roots of the tree grow longer, his territory further expands.

Ye Feng made some estimates and found that the amount of spiritual energy he could harvest now would be roughly 100 points of spiritual energy in one hour.

"At this rate, wouldn't it be possible for me to break through in another four hours?" Ye Feng was a little excited.

This gave him the illusion that the stronger he was, the faster he would break through.

But soon, he discovered that the situation was different from what he thought.

Not that anything went wrong.

But he forgot to include the cost of cultivating mutant animals.

During the day, they can hunt by themselves. Not only can they "feed" themselves, but they also have plenty of spiritual energy.

But at night, as the number of prey decreases and the difficulty of hunting increases, and these mutated creatures also need to rest, Ye Feng is basically raising them.

And now the seven mutated creatures under his command, all added up, will consume a full 40 points of spiritual energy in one hour.

Even excluding the mutant rats that were at the bottleneck, he had to provide at least 37 points of spiritual energy every hour.

So in the end, the spiritual energy left to Ye Feng was only 63 points.

Of course, this is a lot, but it just doesn't allow him to reach 4 hours and break through this standard.

At 6 o'clock in the morning, as the sun rose, Ye Feng also woke up from his short sleep.

He glanced at the mutant animals that were rising up under the tree one after another, with bright spirits, and a smile appeared at the corner of his mouth.

Although he did not break through in the second half of the night, these mutated creatures made breakthroughs one after another as he continued to feed them spiritual energy.

Sparrows, black crows, and bats once again broke through.

They have all reached the first level peak.

It can be said that now, except for the mutated buffalo that he subdued just last night, the rest of the creatures are already at the peak of the first level.

Even the mutated buffalo in the early stage of the first stage has now broken through to the middle stage of the first stage, and is not far away from the late stage of the first stage.

The rapid breakthrough of these mutated creatures also made Ye Feng realize that as long as there is enough spiritual energy, these animals can mutate much faster than humans imagined.

Fortunately, the other mutated creatures do not have such perverted devouring abilities as him.

They can only rely on breathing to absorb the spiritual energy between heaven and earth, so the speed of accumulating spiritual energy is very slow.

As for why some mutated organisms evolve very quickly, he can only classify them as biological differentiation.

At the same time, through observation and statistics, he also discovered another thing.

The rest of the mutated animals are the same as him. Each realm has an upper limit for the spiritual energy absorbed. As long as it is reached, it can be broken through.

For example, a sparrow can break through a small realm by absorbing 10 points of spiritual energy.

Rats need 15 points of spiritual energy to break through.

Black crows and bats require 20 points of spiritual energy breakthrough.

The King Cobra requires 50 points of spiritual energy to break through.

As for the largest mutant buffalo, it requires 60 points of spiritual energy.

Judging from the current situation, the larger the creature, the more spiritual energy it needs to absorb to break through.

Of course, the amount of spiritual energy absorbed is not entirely judged based on body shape.

After all, a mutated sparrow can break through by absorbing 10 points of spiritual energy, but a mutated buffalo requires 60 points of spiritual energy.

But the size difference between them is not 6 times, but 600 times.

Therefore, Ye Feng estimates that the amount of spiritual energy absorbed is not only related to their size, but also related to their realm.

But it is undeniable that in the same realm, the more spiritual energy absorbed, the stronger the combat effectiveness seems to be.

"If calculated according to this, I need to absorb 100 points of spiritual energy to break through at the first level. I should belong to the strongest echelon." Ye Feng concluded.
