This night, Ye Feng spent all his time in cultivation, but Zhou Hui and the ten chefs were very busy, they worked until five o'clock in the morning before they made a ton of Tiger R into one dish after another.

At this time, in Ye Feng's evolution box, there were nearly a thousand stacks of various dishes.

The space inside the evolution box is very peculiar, Ye Feng has done some experiments, and it seems that the food will not spoil at all after putting it in, and it is precisely for this reason that he let these chefs cook a ton of tiger R.

When these chefs were sent away, Ye Feng gave each of them 300 first-order evolution R as a reward, and these chefs were flushed with excitement.

They didn't expect that helping Ye Feng do a night thing would be more than a month's salary for their usual hard work.

And Ye Feng also clearly told them that in a few days, he would ask them to come over to help cook and get them ready.

Of course, these people agreed to come down, you must know that they have seen the spotted tiger that Ye Feng took out, and it weighs at least ** ton, which can make them come over to cook several times.

With enough mutant animal R, Ye Feng no longer saved money, but let go of his belly and ate it.

In the next three days, Ye Feng almost never left his residence, and most of the time, he was either refining his true qi or eating mutant tiger R to improve his strength.

In this way, it soon came the third day, and during these three days, the entire Xin'an City base was like a high-speed war machine, and everyone was preparing for the big war.

And Ye Feng has also sent the Dragon Tooth team many times to enter the urban area to explore the situation, so that Peng De and the others can better formulate plans.

As for the training of the army, in the three-day intensive training, at least the basic attack formation was learned, and as for the S-strike skills, it was only after waiting on the battlefield and slowly honing them with actual combat.

And the best of all the arrangements can be said to be in the logistics aspect. Sun Xue arranged these things almost on the first day, and nearly eighty percent of the ammunition reserves in Shuangzhou City were pulled back.

It is precisely because of these ammunition that Ye Feng has the confidence to clean up the zombies in Xin'an City.

Otherwise, with the output of bullets from the two ammunition production lines in the base, it would not be able to support such a war at all.

Of course, Peng De also proposed to Ye Feng many times that a large amount of manpower and material resources should be invested to create a few more bullet production lines, but they were all rejected by Ye Feng one by one.

Because Ye Feng knew very well that with the continuous enhancement of the corpses, the current guns and ammunition were not suitable for future wars.

Therefore, according to Ye Feng's idea, he would rather store these resources, wait for new weapons to be developed, and then invest these resources to increase productivity.

Of course, in these three days of preparation, the only fly in the ointment is the recruitment of new recruits.

Perhaps because of Ye Feng's ******, when the survivors in the base learned that they would go to the battlefield immediately after joining the army, many people would hesitate.

This slowed down the enthusiasm of these survivors to join the army. Of course, this problem is harmless.

Over the course of three days, they also recruited nearly 6,000 men, bringing their total strength to 16,000.

On average, each division can have 8,000 men in two divisions, and such a force is more than enough to carry out this clean-up operation.

However, that night, while having dinner, Sun Xue reminded Ye Feng of something that he had almost forgotten.

"Brother Ye Feng, the shells of the first batch of tanks we made in cooperation with the Tianhai Alliance, a total of 21 tanks, have been completed."

"When do we transact with each other? Now that we're busy cleaning up the zombies in Xin'an City, should we inform them of the delayed transaction? After dinner, Sun Xue came to Ye Feng's side and asked.

"No, anyway, this is the first deal between the two of us, and it's not good to delay." Ye Feng touched his chin and said after thinking for a while.

"Okay, then I'll arrange logistics personnel here and send this batch of main battle tanks over." Sun Xue nodded and said.

"Don't be in such a hurry, the shells of this batch of tanks, and the last process have not been completed, so they will be sent to Wu Ming's laboratory first, and after completing the last step, I will personally send someone to send them over." Ye Feng opened his mouth and said.

"There's still one more work to be done?" Sun Xue was a little puzzled. But she immediately thought of something, and said in surprise: "You want to do something on this batch of tanks?" ”

"Well, that's right." Ye Feng said with a smile.

The conversation between Ye Feng and Sun Xue did not deliberately lower his voice, and the people around him could hear it, and at this time, Wu Ming finally couldn't help it.

"Brother Feng, why didn't you tell me about this earlier, it's not easy to do something about the main structure of the main battle tank and not let the other party's technicians find out. I can't come up with a good plan all at once! There was eagerness in Wu Ming's voice, and there were also some complaints.

Ye Feng's calm words just now, this was obviously thought out a long time ago, but now he brought it up, isn't this a trick for him?

Hearing the complaint in Wu Ming's tone, Ye Feng raised his hand to signal him to be calm, "I already have a method of how to do my hands and feet, you can just bring someone out to work overnight." ”

As soon as Ye Feng said this, he took out a piece of paper from the evolution box and handed it to Wu Ming.

Wu Ming took it and looked at it, there were several metal names written on it, and even some were chemical raw materials.

"Brother Feng, what is this?" Wu Ming asked with some confusion. Even with his knowledge, he couldn't understand what these metals and chemical materials were.

"By mixing these materials with the claws of the dead claws in the proportions marked on the paper, a special alloy can be made."

"This alloy is much harder than other metals. Of course, this is not the point, the important thing is that it has a characteristic, and that is the frequency of one of the ultrasonic waves, which has the property of resonance. ”

"As long as you add this metal to some important parts of the shell of the main battle tank, we use high-power ultrasonic generators to make this metal resonate, and they will vibrate at high frequency."

"When the time comes, this alloy will be like a cutting attribute weapon we developed, slicing through all the metal around it." Ye Feng opened his mouth and introduced.

Hearing Ye Feng's introduction, Wu Ming immediately swallowed a mouthful of saliva, he knew very well that if this special alloy was used on those key parts, as long as they wanted it, they could instantly tear these main battle tanks apart.
