"It's not okay to go on like this, the amount of food in the second order is so large, and when you reach the third order, if you want to maintain a strong physique, the need for energy will only be greater, and it will not be strange to eat 50 mutant bats a day at that time." Ye Feng felt a little headache.

As for the higher fourth order, he couldn't even think of it.

Perhaps, this is also a way for nature to curb the emergence of higher-order organisms.

If the ecological environment cannot be nurtured, nature will not be born.

But in this case, it will bring Ye Feng a lot of trouble.

But for a while, he couldn't think of any better way, so he could only put this problem aside, and if it really didn't work, he would try to feed them mutant animals later.

When they finished their dinner, the mutant buffalo, the mutant bat, the mutant black crow, the mutant rat and the two mutant sparrows, the first batch of captured mutant creatures, also entered the state of breakthrough.

They're about to break through to the middle of the second order.

An hour later, the six mutated animals had successfully broken through, and their sizes had almost swelled again.

It is worth mentioning that the mutant buffalo became the 4th loyal man, reaching 100% of his subordinates.

"You've all broken through, it's time for me." Ye Feng couldn't help but mutter.

He opened the system panel and took a look, and the evolution point had reached 100/120.

There are still 20 evolution points left to break through.

Converted to 400 points of aura, with the speed at which he is harvesting aura, it won't take long.

However, Ye Feng kept waiting, waiting.

When the time came, at 1 a.m., he finally began to break through.

In fact, three hours ago, the evolution point was full.

But tonight's night was too good, and he didn't dare to evolve until this moment when the top of his head was covered by clouds, and he began to break through.

There is no way, he is now on the key watch list, and he is really worried that the satellite above his head will always be watching.

His breakthrough speed is a little too fast compared to ordinary creatures, he can soar 30 meters in just half an hour, and if it is observed and recorded, it is estimated that he will be able to soar a lot on the danger list tomorrow.

Therefore, he tried to avoid these troubles as much as he could, not only choosing to break through at night, but also when there were clouds covering him.

And after knowing that he was being focused on, Ye Feng wanted to prevent problems from being detected by satellites in the sky.

He had stopped, extracting the aura of a dozen trees beside him.

Not only that, but it also gives them 1 point of aura every hour, in order to make them grow faster.

The trees might not be too tall, but they must be dense enough to help him block out all the mutated creatures under the trees.

Even just in case, a mutated creature like a mutant buffalo that is large and easy to show its stuffing, he asked the other party not to get close to his 500 meters.

As for the issue of replenishing Reiki, it is enough to extend the taproot once an hour.

And he did so much so so that the relevant departments would not find out that he was able to domesticate mutant animals.

Ye Feng opened the system panel and finally confirmed the data.

After some additions, the length of his roots has increased from 430 meters after the breakthrough to 550 meters.

Just adding points is a full 120 meters of improvement.

This also made Ye Feng feel that as the realm became higher and higher, the magnitude of the small level improvement would become more and more exaggerated.

Now that he has raised one level, it is worth the amplitude of three small ranks when he is second order.

"Ding! Please select the direction of reinforcement. ”

Without much hesitation, Ye Feng directly chose to strengthen his strength first.

The next moment, his body began to grow rapidly, and the height of the tree could increase by one meter almost every minute.

And in the process, branches and leaves continue to grow, and the scope of his canopy becomes larger and larger.

Of course, the biggest change is actually the roots of the trees underground.

Each of the 303 roots, each thigh-thick and 650 meters long, would be even larger than his body if all of them were gathered.

And now, these 300 tree roots are growing rapidly, and at the same time, they will also squeeze the soil, and even cause a slight tremor in the ground.

Although the scope of this impact is not large, it is appalling enough.

Finally, half an hour later, the breakthrough ended, and Ye Feng checked the panel for the first time.

Host: Leaf Maple (World Tree)

Tree height: 125 meters

Trunk width: 6 m

Root length: 610 m

Realm: Middle of the Third Order

Evolution point: 0/120

Special Abilities: Devour, Capture, Evolution Fruit

Aura: 200/1200 points

Bioenergy: 950/1200 HP

"It's already 125 meters! With my current breakthrough speed, it is estimated that it will not take a week or two to surpass the old locust tree on Xiaofeng Mountain. Although he had expected it before breaking through, Ye Feng still sighed when he looked at the system panel.

At that time, it is estimated that the eyes of the research team will be all focused on him.

After Ye Feng glanced at the height, his gaze continued to move downward.

As the width of the tree increases, the aura value and biological energy he can store are also increasing, and it is difficult for a situation like the previous one that has to be broken through again.

After all, in addition to the huge increase in his own storage, he also needs to feed more and more subordinates.

"Although aura will not be wasted, biological energy is!" Ye Feng was a little distressed.

He can only use biological energy for his own use, so there will be more and more leftover in the future until it is wasted.

He also tried to reverse devour his ability to replenish his creatures, but failed.

Ye Feng suppressed these thoughts and set his eyes on the length of the tree roots.

This attribute never disappoints him.

The length of 600 meters is exaggerated.

He estimated that with the current range of his territory, he would be able to harvest at least 300 points of aura per hour.

Even if it is deducted, the 168 points of aura spent on cultivating his subordinates per hour can still have 132 points left, which greatly alleviates the problem of insufficient aura.

After all, if you can have 132 points of aura left in an hour, then 24 hours a day, you can save 3168 points of aura, which can fully meet his requirement to break through once a day.

In addition, he was pleasantly surprised by the power of these roots.

As his strength reached the third order, the magnitude of his strength enhancement this time was also unprecedentedly large, directly increasing the strength of each of his roots from 500 jin to 1,000 jin.

Now all the strength of his 303 tree roots has been gathered, and he can burst out with a huge force of 151.5 tons.

"With more than 150 tons of huge power, with one blow, you can slap the rest of the third-order mutant creatures into pulp!" At this moment, Ye Feng really has a feeling of being invincible in the world.

Of course, Ye Feng's excitement didn't last long, because he could only be invincible within his own 'territory'.

If the other party doesn't come in, he can't do anything.

Of course, he is not depressed, after all, he is not alone, and there are a group of powerful subordinates.

Now he has begun to look forward to how powerful it will be when the group of mutant animals under his command all break through to the third order.

Thinking about these things, his eyes involuntarily looked at the king cobra.

Because of calculating the time, the other party is about to break through to the peak of the second order, and at that time, there will only be one step left before the third order.
