His words immediately made the researchers in the field fall into deep thought.

In the end, everyone's eyes were on Xu Liang, and he was the one who had the most right to speak.

After pondering for a while, Xu Liang said slowly: "According to our research theory, all plants that have mutated to a certain extent can purify the essence of life, and it stands to reason that this iron birch tree should also be able to do so." ”

"But its height is not as good as that of the mutated old locust tree after all, and we need more materials, I'm afraid it needs at least 300 catties."

This suddenly made everyone in the audience feel refreshed.

As long as you reach your destination, whether you collect 100 catties or 300 catties, the difficulty is the same.

Seeing that everyone was a little excited, Xu Liang reminded: "Although the mutated iron birch tree in Sunset Valley is chosen, the danger level can be reduced a lot. ”

"But no matter how much you reduce it, the risk is still very large, and I'm afraid it will be difficult to find someone to take over such a task."

Yi Weihua said again: "I have a suggestion, I know the owner of a security company, and he may be willing to take on this task. ”

"Security company?" Xu Liang's eyes suddenly lit up.

Compared with ordinary people, the probability of success of people from security companies will undoubtedly be much greater.

"Ahem! Not a regular security company. Yi Weihua saw everyone's puzzled eyes, and hurriedly explained: "I mean, legally he is a security company, but what he does is not the business of a security company." ”

"Tell me what the hell is going on?" Xu Liang frowned.

"To put it simply, their main business is to lend money, and the boss has a large group of thugs." Yi Weihua said.

Everyone in the audience instantly understood what he meant.

"Is this kind of thing reliable for them?" Xu Liang's brows furrowed tighter and tighter.

"They are one of the few people who dare to take on such a high-risk mission."

"And some time ago, after a round of crackdown, they no longer dare to do this kind of gray business, and now the boss is probably worried about where to get money!"

"3 million is enough to make them tempted, and we can sign a contract with them, give half of the deposit first, and then pay the balance after success, they will definitely work hard." Yi Weihua said.

"Just pay half the money upfront, are they willing?" Xu Liang asked.

"I don't know, but we can try. And in the face of such a group, we don't need to convince every member, as long as their boss agrees. Yi Weihua said.

The researchers in the audience looked at each other, and felt that such a proposal seemed feasible.

"Okay, you go and contact the boss and ask him to come and talk." In the end, Xu Liang made a decision.

……

Ye Feng naturally didn't know what he was worried about, it had come true.

However, at the moment when he chose to break through, he was already mentally prepared.

So at this time, although he was in a heavy mood, he was not panicked, and he was just doing his own thing step by step.

Harvest the aura, add points, inject aura into these mutated animals, and finally possess the two little sparrows from time to time to see the progress of their search.

But I don't know where the mutant boar is hiding, and after three hours of searching, I still found nothing.

"I've searched for nearly 10 kilometers in the vicinity, and it won't have left the surrounding area!" Ye Feng frowned slightly.

Of course, it cannot be ruled out that the search is not careful and misses the case.

Although the mutant wild boar is very large, with the mutation of plants, trees more than ten meters high can be seen everywhere, and it is very likely to be missed simply by searching at high altitudes.

But if you choose to search in the carpet, it is impossible to use these animals under his command.

"Count the time, it's time for them to come back." Ye Feng muttered an order to return.

In order to allow this group of subordinates to improve their strength faster, Ye Feng would inject aura into their bodies every hour.

It is worth mentioning that as they broke through to the second order, the amount of spiritual energy devoured by each animal increased greatly.

Now these 9 animals combined, they will swallow 84 points of aura in an hour.

However, Ye Feng didn't care about this consumption, he planned to only raise a small level every day, and the remaining aura was completely enough for him.

According to the experience gained from the king cobra, as long as these mutated animals have sufficient aura, even when they reach the second order, they can basically break through once in 10 hours.

In this way, in two days at most, he would be able to directly cultivate this batch of second-order mutant animals to the third-order.

At the same time, Ye Feng made a ranking of the aura that they could absorb every time they broke through a small realm at the second order.

1. Mutant King Cobra: 200 aura

2. Mutant Buffalo: 200 aura

3. Mutant Black Crow: 80 aura

4. Mutant bat: 80 aura

5. Mutant Mouse: 60 points of aura

6. Mutant Sparrow: 40 points of aura

As for the remaining big yellow dogs and parrots, they are only first-order for the time being, and they are not included in the calculation for the time being.

How much Reiki these animals absorb to break through often means how much potential they have.

It is worth mentioning that at the first order, the aura required for the mutant buffalo to break through is 10 points more than that of the king cobra.

But when it comes to the second order, the amount of aura they can absorb per hour is already the same.

This had to give Ye Feng a new guess, and the mutant creatures that broke through on their own would have greater potential.

While he was thinking about these things, his subordinates also returned one after another, although they did not find the mutated boar, but some of the mutant creatures they encountered would also be hunted and killed, and then brought back to Ye Feng to devour.

And at this time, with the return of these animals, one mutant animal after another was placed in front of Ye Feng.

6 mutant rats, 3 mutant pheasants, 2 mutant toads, 2 mutant tree frogs, 1 mutant weasel.

In addition, the air brigade also brought back Ye Feng, 3 mutant bats, and 2 mutant pigeons.

And some of these mutated creatures are dead, and some are alive.

Whether it is dead or alive, Ye Feng can directly devour and absorb it.

But if you die, you can't take it prisoner.

However, he glanced at the mutated animals in front of him, and he had no intention of capturing them at all, and devoured them all.

"Why is King Cobra coming back so slowly this time?" Ye Feng was a little puzzled, but not long after, the king cobra also appeared in his field of vision.

It also had a mutated creature wrapped around its tail, and when he saw the appearance of that creature clearly, Ye Feng's face suddenly showed an interested expression.

It was a mutated hedgehog.

Although the hedgehog is also a small-sized creature, due to its characteristics full of thorns, maybe after the level is high, its combat effectiveness is not weak, so this is also one of the animals on Ye Feng's prisoner list.

"It's really my blessing!" Ye Feng looked at the king cobra and said with emotion.

Whether it's a mutant buffalo or a big yellow dog, it's all brought back.
