After receiving Ye Feng's promise, Zhang Ji took 10 spiritual qi fruits and left quickly.

The mutant creature crisis could erupt at any time, so he had to go back and report on this matter quickly, and after finalizing the plan, he would come to further negotiations.

After seeing the other party leave in a military jeep, Ye Feng also began to frown and ponder.

The last time the biological crisis of the "four pests" broke out in the city, compared with this time, it is really just a drop in the bucket.

Although he believed that with the strength of the Dragon King Palace, he could play a pivotal role in this crisis, but it was really hard to say whether he could keep Yang City.

"I hope the military will help you a little bit!" In the end, Ye Feng could only mutter.

In the entire Yangcheng City, except for the old city where his parents are located, he must keep it, and other places can only be said to do his best.

"Just in case, it's time for me to continue to improve my strength."

Thinking of this, he clicked on the system panel and looked at it.

Host: Leaf Maple (World Tree)

Tree height: 2085 meters

Trunk width: 104 m

Root length: 12,400 m

Realm: Late Fifth Order

Evolution points: 1900/2000 points

Special Abilities: Devour, Captive, Evolution Fruit, Mental Power, Life Healing

Aura: 0/20800 points

Bioenergy: 19,000/20,800 points

Power of Faith: 332,600 points

Looking at the system panel, Ye Feng couldn't help but show a smile on his face.

In the past ten days, even the contract animals have improved so much, and his improvement is naturally more exaggerated.

The height of the tree body was directly increased by 1,000 meters, reaching 2,000 meters, and basically under the condition of good weather, the residents of the entire Yangcheng City could see him when they looked in the direction of Xiaofeng Mountain.

Even the diameter of the trunk has exceeded 100 meters, reaching a full 104 meters, which is the diameter, if you calculate the cross-sectional area of the trunk, it is almost 8,490 square meters.

Of course, the most exaggerated thing is the length of the tree roots, which has skyrocketed from 4,500 meters when it just broke through the fifth order to 12,400 meters.

The root length will increase so much, it will increase by 1000 meters when it breaks through, and it is only secondary, and the more important thing is the increase in the root length when adding points.

Every time Ye Feng added points, the length of the roots could increase by 10 centimeters, and he needed to add points 20,000 times to be able to accumulate 2,000 evolution points.

In other words, the length of the tree can be increased by a full 2,000 meters by simply adding a few roots.

When he first broke through the early stage of the fifth order, the root of the tree was 4,500 meters, and as long as he completed the addition point later, he didn't need to break through, and the root length could increase to 6,500 meters.

In addition, when he broke through, he increased the root length by an additional 1,000 meters, which means that at the fifth level, he could increase the root length by 3,000 meters by improving a small realm.

And the sudden increase in the length of the tree roots, the total amount of spiritual energy that can be harvested per hour is naturally also skyrocketing.

Now the aura he can harvest per hour has skyrocketed from 7,200 points when he first entered the fifth order to more than 19,800 points.

Because of this, the breakthrough time was also much earlier than he had expected.

Now his evolution points have reached 1900, and he is only 100 points away from being able to break through to the peak of the fifth order.

Although 100 evolution points require 20,000 spiritual energy, it is really nothing to Ye Feng now, and it can be enough in about an hour.

However, Ye Feng was not in a hurry, he planned to wait for tonight to break through, after all, there was a thick fog in broad daylight, which was too conspicuous.

Of course, every time he breaks through, the entire Sunset Valley will be foggy, and it is estimated that the high-level of Yang City has already guessed something, especially the height of his current tree, even ordinary people will feel that there is a problem when they see it.

But the two sides are now in the honeymoon period, and it is good to know some things, and no one will pierce that layer of window paper.

After breaking through to the peak of the fifth order tonight, he would be able to expand another 10 kilometers to the extent of a full 65 kilometers by controlling the casting distance of heaven and earth.

In that case, it can almost envelop the entire Yang City.

Coupled with the 332,600 points of faith power accumulated in the past 10 days, it should be able to deal with all emergencies.

While thinking about these things, Ye Feng released his spiritual power and began to sweep with himself as the center, a range of 25 kilometers in diameter, and count the subordinate strength of the contract animal.

After all, there was no information about them displayed on the attached panel, so if he wanted to understand their strength, Ye Feng had to use his spiritual power to probe.

After reaching the fifth order, the exploration distance of Ye Feng's spiritual power had increased from 1 km before to 5 km.

Of course, this refers to the limit distance that can be explored after being separated from the body.

You must know that the length of Ye Feng's roots has reached 12,400 meters, that is, 12.4 kilometers, on this basis, extending 5 kilometers outward, the limit distance he can explore is 17.5 kilometers, and this is only the radius, the diameter can reach 35 kilometers.

Within this range, Ye Feng's spiritual power can be swept quickly, even if it is a mutant ant, don't want to evade his detection.

It is worth mentioning that as the roots of the tree have grown beyond the Sunset Valley, his "territorial range" has naturally expanded, so the animals in the valley have been allowed to go out, as long as they do not exceed the range of his roots.

Because of this, many mutated creatures have now left Sunset Valley and are living in the Dongling Mountains.

This scene is also what Ye Feng is happy to see, after all, so many mutant creatures are piled up here in Sunset Valley, and every day in order to solve the food of those carnivores, he needs to capture at least a thousand mutant mice and put them in.

Now that they have gone to the Dongling Mountain Range, they can just hunt mutant rats by themselves, which makes Ye Feng worry a lot.

It is worth mentioning that the second-order mutant rat is already comparable to a small dog in size, and it is a second-order mutant creature, which contains a lot of energy in its body.

Therefore, even if it is a large-sized animal such as a second-order tiger or lions, eating seven or eight mutant mice at a meal is almost enough.

Ye Feng's speed of exploration was very fast, and it didn't take long to count it.

The first is the air force, with 800 mutant sparrows, 400 mutated black crows, 400 mutated bats, 10 mutated parrots, and 5 mutated goshawks.

The size of the air forces is not much different from the previous ones, but the ground forces have changed greatly.

400 mutant dogs, 400 mutant mice, 100 mutant buffaloes, 50 mutant wild wolves, 35 mutant honey badgers, 30 mutant hedgehogs, 30 mutated Siberian tigers, 30 mutated Asiatic lions, 28 mutated white rhinoceros, 25 mutated African elephants, 25 mutated hippos, 20 mutated brown bears, 20 mutant jaguars, 10 mutated giant pandas, and 10 mutated king cobras.

It can be said that the strength of the ground forces, compared with before, has definitely increased by several levels.

After all, there were no ground troops at all before, and there were even only 400 mutant rats that could survive the scene.

But now it's different, not to mention anything else, just those 400 mutant dogs have directly increased the overall strength of the ground forces several times.

Moreover, the 400 mutant dogs that Ye Feng took the lead in letting the big yellow dog control are all large dogs, such as police dogs, golden retrievers, Labradors, Alaskan Malamutes, Rottweilers, Kaslos, Samoyeds, Tibetan mastiffs, Scottish Shepherds, etc.

These large dogs are not much inferior to mutant wolves in terms of combat power, 400 second-order mutant dogs, under the situation of unified scheduling, according to Ye Feng's estimates, can easily annihilate more than two regiments of troops on the frontal battlefield.

In addition to these mutant dogs, the number of mutant buffaloes has also skyrocketed to a full 100, and if you put them on the battlefield, it is literally 100 mobile tanks.

However, if you want to increase like this in the future, it is estimated that it will not be easy, these mutant buffaloes were all sent by Ye Feng to find the mutant goshawks in Yang City and even in the surrounding cities.

If you want to find it in the future, it is estimated that you will have to look for it across cities or buy it directly.

As for the rest of them, although the number is a little less, they are also the top one.

In particular, Siberian tigers, Asiatic lions, African elephants, white rhinoceros, hippos, and brown bears, these mutated creatures brought out of the zoo are far more powerful than ordinary mutant creatures in the same class.

If we put them on the battlefield, although we dare not say that we will turn the tide, we will have no problem at all in changing the trend of local wars.

Of course, in addition to the air force and ground force, Ye Feng has now also divided an insect force.

The insect army is a unit composed of mutated red fire ants and mutant bumblebees.

After more than ten days of development, the number of ant colonies and bee colonies has increased a lot, and they have exceeded the 20,000 mark.

In other words, the strength of the insect army is as high as 40,000.

And the reason why Ye Feng wanted to list a separate insect unit was naturally for a reason.

Ten days ago, the mutated red fire ant queen and the mutant bumblebee queen broke through to the third order one after another.

Then Ye Feng discovered that after they broke through to the third order, the eggs they laid were different, they were larger than the previous eggs, and the larvae after hatching were also stronger than before.

Of course, if it was just that, Ye Feng wouldn't pay too much attention.

What really surprised him was that the speed of development of these new ants, from eggs to larvae, then to pupa, and finally to ants, took only 4 days.

Then, out of curiosity, Ye Feng sent an evolution fruit, so that this latest batch of ants had enough aura to grow.

Moistened by aura from birth, and with abundant food, these latest generation of mutant red fire ants grow at a rate like blowing up balloons, which is completely the same every day.

Of course, what Ye Feng cares about the most is their realm.

Even the little ants that had just broken out of the chrysalis, their cultivation speed was actually no different from the rest of the animals, and in just one day, they broke through from the first order to the second order.

Then it took another two days to rise to the peak of the second order.

Originally, Ye Feng thought that it would be over at this time, after all, the current level of aura could only support these mutated creatures and break through to the second order on a large scale.

But something happened to Ye Feng's surprise, as if there was no bottleneck in the new generation of these red fire ants, they simply broke through to the third order.

If it was just a mutant red fire ant, Ye Feng wouldn't care, maybe he was talented.

But the entire 300 mutant red fire ants in the same batch, without exception, all broke through to the third order, so the meaning was completely different.

And it's not just the mutant red fire ants, but also the baby bees that hatch from the mutant bumblebees.

In the end, according to Ye Feng's guess, the reason why this is the case should be related to the queen ant and queen bee, breaking through to the third order.

They have broken through to the third order, which means that they are third-order creatures, and the offspring born can naturally break through to the third order.

After coming to this conclusion, the status of the queen ant and queen bee in Ye Feng's heart was instantly elevated to the point of being on par with those mutated creatures that could break through on their own.

After all, this means that as long as the realm of the queen ant and queen bee is raised in the future, it is equivalent to raising the realm height of the entire race.

When the time comes, the overall realm of ant colonies and bee colonies will far exceed those of the subordinates of the rest of the contract animals.

After all, their realm can only follow the process of aura recovery, although Ye Feng can provide them with aura, he has no intention of helping them break through the realm.

After all, that's too expensive.

The first-order and second-order evolution fruits, Ye Feng gritted his teeth and could afford it.

However, for a third-order Evolution Fruit, you need a full 1200 aura points and bioenergy to make one.

And when it comes to the fourth-order Evolution Fruit, the required aura value and biological energy have soared to 20,000 points.

Each of the contract animal's subordinates sends an evolution fruit, so he doesn't need to improve his strength.

What's more, there are fifth, sixth, and even higher levels behind it.

Because of this, the role of the queen ant and the queen bee is instantly highlighted.

And according to their current cultivation speed, I am afraid that in about five days, they will be able to break through to the fourth order.

At that time, the new batch of mutant red fire ants and mutant bumblebees produced will be able to break through to the fourth order.

Although it is said that the fourth-order mutant ants and bees will definitely not be able to defeat the other fourth-order mutant animals, but 1 can't be defeated, so what about 10 or 100!

As the saying goes, as long as there are enough ants, there is nothing to worry about.

What's more, the positioning that Ye Feng gave them was never to deal with mutated animals of the same level, but to deal with enemies of a lower level than them.

When the time comes, if you have the advantage in realm and quantity, the effect will be terrifying.

As for whether there will not be so much aura cultivation after the number of ant colonies and bee colonies increases, Ye Feng is not worried about this problem.

On the one hand, the speed at which he collects aura will get faster and faster in the future.

On the other hand, these ants and bees absorb very little aura, only about 1% of the same level mutant dogs.

So don't look at the current insect troops with a full number of 40,000, but in fact, the aura they consume is only about the same as 400 mutant dogs.

"It's only now that my animal legion is truly formed." After Ye Feng finished counting the subordinates of the contract animals, he couldn't help but sigh with emotion.
