In the dead of night, the moon is reflected in the lake of the community, sparkling in patches.

There is an artificially built stone road in the small courtyard of Ye Yu's house, and you can reach the lake by walking down all the way.

"Slash!"

Ye Yu instantly drew his knife, and an invisible breath swept across the lake, and the reflection of the moon in the water was directly fragmented, and then quickly restored.

"It's not fast enough!"

"When you can split the reflection of the moon in two with a single sword, you have reached the stage of proficiency. ”

The dust floating in the air popped up a blue light curtain and explained to Ye Yu.

"Angle and speed matter. You are now holding the knife with your own hand, which is not the same as holding the knife with the hand of the mech. ”

"You will become proficient after a long time of training, but you can't use mechs, you have to remember the exact values of power, angle, and speed of each knife draw to ensure that you can use the mecha energy to get as many knives as possible. ”

Weichen said, and the "Bomb Fortress" mecha that Liu Xu gave to Ye Yu appeared on the light curtain, a ten-meter-tall mecha with a five-meter giant knife.

Gather strength, draw the knife, slash!

In the next second, a crack appeared on the virtual ground on the light curtain that was more than ten meters wide and four or five meters deep.

"With your current proficiency in knife drawing, this mech only has enough energy to draw your sword once. ”

"So, once you break through the entry stage, the energy of this mech can support you to draw your sword twice. ”

After finishing speaking, Weichen put away the light curtain, while Ye Yu stood still in place, recalling the scene of the knife pulled out just now.

It wasn't until half an hour had passed before Ye Yu spoke: "How much metal does it take to build a giant knife like that just now, and how much does it weigh?"

"The base weight of the Bomb Fortress mecha is 11.8 tons, and if it is fully equipped with weapons, it is 14.6 tons, and the weight of this knife cannot exceed one meal, otherwise the mecha's movement speed will be reduced by half, and the energy consumption will be accelerated by one-third. ”

The light curtain reappeared, and the picture showed the mecha carrying a giant sword.

"You can't do more than one meal, then you can only choose a metal with light weight and hardness, and there are only a few rare metals that can meet this standard, and the price of each is sky-high. ”

Ye Yu frowned, it was a pity that the Light Energy Knife was not suitable for the Knife Drawing Technique, but he definitely didn't have that much money to buy a rare metal close to a ton.

"Tomorrow, I'll go to Mr. Qin and ask if there's a way to solve it. ”

Ye Yu said helplessly, even if he added all the 10 million federal coins left by his father, it would be a drop in the bucket, far from enough to make a knife.

"There is also a way, reduce the thermal weapons of the mecha, half or one-third of the assembly, so that the weight is reduced a lot, and you can use conventional metal to build a knife. "Mote gives its advice.

"No, if that were the case, I wouldn't have chosen Bomb Fortress in the first place. Thermal weapons are the strength of this mech. ”

"And at the moment I can only draw the knife once, and in this case, it feels like the cost of reducing the thermal weapon is a bit more than worth the loss. ”

Ye Yu rejected Weichen's suggestion without thinking about it.

"Take your time and find a way to make money first. ”

After speaking, Ye Yu turned around and walked home, it was already very late, tomorrow was the first day of college, and he had to have a good spirit.

......

Early the next morning, in the office of the dean of the Yancheng Mecha Academy, Ye Yu stood at Qin Xiaotian's desk and spread his hands helplessly.

Before coming to the academy, Ye Yu wondered if there would be anyone who was not convinced that he had taken a place to go to the main school and would come to challenge him.

It turned out that Ye Yu was thinking too much, this class of freshmen, in fact, he and Ye Yinxin were certified first-order mecha masters, and the others were still a little behind.

I thought that this matter would be like this, just wait to go to the Demon Capital Colonel, but the challenge of the Yancheng Federal Military Academy came to the door.

The two special students of the Federal Military Academy wanted to challenge him and Ye Yinxin to determine who was the first mecha master in Yancheng's freshman class.

"Teacher, I have an idea. ”

"I can accept the challenge, but it has to be conditional. ”

Ye Yu thought about the knife and felt that he could give it a try.

Then, Ye Yu told Qin Xiaotian what he needed to make a knife, hoping that he would bring it up to the Federal Military Academy.

"You mean, a metal knife that is five meters long and can't weigh more than a meal?"

"If you don't use a good light energy knife, how can you think of using a metal knife?"

Qin Xiaotian was puzzled, feeling that Ye Yu was a bit of a loser.

According to Qin Xiaotian's estimate, the cost of building such a knife would require at least 100 million federal coins, which can be called a sky-high price.

"Teacher, if they don't agree, then I won't compare, whoever likes to be the first will be the first, this has no practical meaning to me, it's more than whoever kills the beast in the future. ”

Ye Yu deliberately said these words to Qin Xiaotian, and he knew very well that this challenge was actually related to the honor of the Yancheng Mecha Academy and the Federal Military Academy.

The new First Mecha Division must be decided.

"Okay, I'll discuss it with Principal Long. ”

Qin Xiaotian gritted his teeth and said, 100 million is not a small amount, although the two schools can take it out, it will not hurt the muscles and bones, but it is also a big piece of meat.

If Ye Yu lost, it was estimated that Qin Xiaotian would vomit blood in pain.

Ten minutes later, Long Long's message came back, agreeing to Ye Yu's request, and at the same time making another request.

If Ye Yu wins, they won't say anything, if Ye Yu loses, then Ye Yu must join the army after he graduates from college.

"Ugh!"

Hearing this request, Ye Yu was a little surprised, but he was not dissatisfied.

The reason is very simple, because Ye Yu never thought that he would lose.

It's not that he's conceited, it's just that.

Ye Yu's qi and blood value had reached three thousand, and it was impossible for anyone of Yan City's peers to surpass him at this value, and it was very difficult to improve his qi and blood.

He can have such a high qi and blood value because of his light brain, and it is impossible for normal people to achieve it at this age by themselves.

Thinking of this, Ye Yu readily agreed to the other party's request.

The competition is scheduled to be held in the afternoon, and the people from the Federal Military Academy are also a man and a woman, the male is called Yu Qiu, and the female Wang Min is eighteen years old, the same as Ye Yu.

After saying this, Ye Yu and Ye Yinxin had a meal with Qin Xiaotian in the cafeteria.

Because they were going to the main school of the magic capital soon, neither of them was assigned a class by the academy.

Before the start of the competition, Ye Yu took a moment to make small changes to the "Bomb Fortress", using convertible values to strengthen the mecha shell, if nothing else, this mecha will accompany him throughout his college career.

Only fifth-order mechs will learn to drive and control large mechs that can reach a height of 100 meters.

Before the fifth order, the mecha about ten meters tall was the favorite of mecha masters, and it was also the mainstream mecha.
