The young master went out shopping to pick a bed, and was cheated by several people. In the end, he bought all kinds of bedding. After swiping the card, he realized that he had to pay for everything.

"You cheated me?" Liao Runing questioned the four people who were looking at the sky and the ground.

"How can you cheat when it comes to friends?" Wei San patted him on the shoulder in a friendly manner, "How about this, let Huo Xuanshan treat us to a meal later."

Huo Xuanshan: "..."

Liao Runing immediately calmed down: "Okay."

Among these people, Jin Ke is the most calculating, but Huo Xuanshan is definitely the most treacherous. Liao Runing used to be like everyone else, thinking that he was a gentleman, but now he understands that Huo Xuanshan is the most shameless one.

After finishing an expensive lunch, Jin Ke and the others went to Wei San's dormitory to change the things, and Ying Chenghe took Wei San to modify the mecha.

"What mecha did you choose?" Ying Chenghe asked.

"This one." Wei San put the mecha out on the open ground.

"Zhu Jiang." Ying Chenghe nodded, "I'll see where I need to modify it."

After that, he went forward to connect the mecha with the optical computer.

Wei San didn't go up, but asked him: "I am now a super 3S level, can I watch Yu Qingfei's teaching?"

Ying Chenghe was stunned, remembering that Wei San could also modify mechas.

"Yes, if you wear a brain interface, you can get in." Ying Chenghe responded, "There is no mecha master beyond 3s in the Federation now. Wei San, I will temporarily help you modify the mecha in the competition, but you may have to design your own mecha in the future."

"Then you help me modify Zhu Jiang here, and I will watch Yu Qingfei's teaching." Wei San immediately wanted to see the mecha science left by Master Yu.

Ying Chenghe raised his hand to turn on the optical computer and help Wei San open the authority: "After entering, don't force yourself. If you feel uncomfortable, come out immediately, otherwise your perception may be damaged."

Wei San got the authority and slipped away immediately.

The machine with the brain interface is on the second floor of the data room they had visited before. Wei San walked through the data room on the first floor and went to the second floor. It was empty except for a slightly higher platform in the middle with a helmet-like brain interface suspended above it.

As soon as she approached, a light blue light barrier suddenly rose up around the platform, making it impossible to get in.

Wei San raised her hand to turn on the authority of the optical computer, and the barrier disappeared again. She stood on the platform and took down the suspended brain interface.

As soon as she got it, she noticed that the brain interface was absorbing her perception.

Wei San remembered what Ying Chenghe said, so she simply released all her perceptions and then put on the brain interface.

As soon as she put it on, her vision changed immediately, or more precisely, it was as if she was trapped in a dark night with a light blue hue.

"Here comes another one."

A young voice suddenly came from behind Wei San. She turned her head and saw a tall and handsome young man, the same as the photo on Starnet.

- Yu Qingfei.

However, Yu Qingfei in the photo was handsome and handsome, and with the added bonus of his glorious history, no one expected that he actually had a bit of evil.

The young man, that is, Yu Qingfei, walked over from behind and stood in front of Wei San, as if he saw her: "Newcomer, are you sure you want to be a mecha pilot?"

Wei San didn't say anything, but walked forward and looked around Yu Qingfei.

This should have been recorded when he was alive. It can be seen that he is in good condition, and there is an unconcealable casualness in his eyes.

"Why don't you talk?" Yu Qingfei said to the air, with Wei San standing behind him.

It seems that Yu Qingfei did not expect that someone would not play by the rules and did not respect him at all!

Wei San saw this and patted him: "Master, here."

Yu Qingfei's corpse turned around immediately: "Don't touch me, are you here to learn mecha? Bad habit."

Wei San: "..."

"Okay, now I'll start teaching you." Yu Qingfei raised his hand and pulled it horizontally, "Here are the corresponding level tutorials, choose."

There were only three options in that row: S, SS, 3S.

Wei San hesitated for a while and directly clicked 3S.

The screen suddenly changed. This time it was in a super large studio, a luxurious studio that Wei San had never seen before.

"Whether you are a kid with no basics or a rubbish mecha master who wants to learn from me." Yu Qingfei suddenly appeared from the side with a utility knife in his hand, "From now on, forget everything and learn from this master." Yu Qingfei

at this time was obviously older than when he first met Yu Qingfei, probably about 30 years old, but the casual arrogance on his body was still there.

"Let's start with the structure of the mecha. Which part of the mecha do you think is the most important?" Yu Qingfei looked at Wei San and didn't give her time to answer, "No matter which one you think is important, now I say which one is important."

Wei San: "..." Okay, you are a master, you are right.

"Energy, engine, motor, weapon, these four are the most important things for a mecha." Yu Qingfei walked to the tool table, pulled a chair and sat down, "These parts are inextricably linked to the materials, and many of our materials come from star beasts. What level of mecha, what level of material, that is, star beasts." Wei San

understood a little, but not quite. She had never touched S-level materials. The finished parts sent by "I have money" before, she didn't have time to study them, because she had a nosebleed and finally put them aside. All the

materials she touched were artificially synthesized materials used in A-level mechas, and she had never heard that A-level used things from star beasts as weapons.

"A-class weapons don't need to use things from star beasts as weapons." Yu Qingfei seemed to have heard what Wei San was thinking, and said, "A-class star beasts are mostly group-living, and lack strength, so they are not good enough to be used as materials, and are even worse than artificial imitation materials. If you want to make an A-class mecha for fun one day, remember not to use A-class star beasts. If you have a chance, you can try to add a little S-class material, but not too much, otherwise the A-class mecha soldier can't bear it. The amount and balance between them need your own research."

Wei San suddenly remembered the mecha of the Grim Reaper in the black factory. The joints seemed to have added S-class materials, but the Grim Reaper was different, it was S-class.

This was later told to her by Huo Xuanshan.

"Today I will talk about materials. It just so happens that the bastard principal got a 3S-class star beast." Yu Qingfei stood up and pushed open a door.

Another scene appeared in Wei San's eyes. This time it was an empty room with only a processing table and a bloody giant sand wolf in the middle.

"This is a giant sand wolf, which can only be found on the planet Shadu." Yu Qingfei squatted in front of the dead sand wolf and pried open its mouth with his gloved hands. "This is a sand wolf that is about to mutate. Although the quality of the material will be better if we wait until it is completely mutated, but... if you encounter a star beast, you must kill it, otherwise I don't know how many people will be hurt in the future."

"Look at its teeth, they are hard and sharp." Yu Qingfei tapped the canine teeth of the sand wolf, "but it is not suitable for making mecha weapons. The weapons of the mecha should be able to be retracted and extended freely, which is beneficial to the movement of the mecha. So I usually choose to remove the teeth of the sand wolf, and add them to the weapon after special treatment."

Yu Qingfei handled the four canine teeth of the sand wolf swiftly, and then the scene changed. It was estimated that several days had passed, because Wei San found that he had changed into new clothes and was standing in the studio.

"Let me show you how to handle the sand wolf teeth." Yu Qingfei said to Wei San's position.

While he was working, he seemed to be chatting: "I heard a piece of news two days ago. When a mecha technician took materials, he did not kill the star beasts, but took the materials while they were alive, because the quality of the materials would be better. Star beasts really only know how to attack humans, and they are beasts without a doubt. But I hope that the students I teach will not use this method in the future. It's not that I sympathize with the star beasts, but if you do this too much, you will have psychological problems."

Yu Qingfei raised his hands and stopped in mid-air, with an unhappy look on his face: "That mecha technician took this crooked path, I hope that there will be no such people in the Federation in the future."

After that, he did not say these things again, and simply taught how to deal with materials mixed with weapon metals.

But Wei San had a hunch that this was the first time that Yu Qingfei showed such a complicated and heavy expression in the teaching video he left behind, and the original casualness and mood sank.

She had just finished learning to process the materials with Yu Qingfei, and suddenly everything in front of her eyes disappeared, and she returned to the empty second floor.

"Wei San, you stayed in there for five hours." Ying Chenghe looked down at his computer. He had just forced Wei San to quit.

Currently, among those who use this instrument-brain interface to learn mechas at Damocles Military Academy, Ying Chenghe is the one with the highest authority.

"Really? I don't remember." Wei San came down from the platform, and his legs went limp.

Ying Chenghe stepped forward to support her: "How was your first class?"

"Very good, starting from the materials." Wei San stood there, her nose bleeding again, but now she was calm inside, and she skillfully blocked her nose with a tissue.

The doctor said it was a sign of recovery of perception.

"Materials?" Ying Chenghe was stunned, "Don't you start with the mecha engine?"

This is a teaching video that the masters have recorded and set the parameters before they died, and imported into the machine. It looks like one-on-one, but in fact everyone is learning the same content.

"No." Wei San looked at Ying Chenghe, "You didn't learn the materials?"

"I did, but you didn't do it in the right order." Ying Chenghe frowned and looked back at the machine, "Maybe it has something to do with you being super 3s."

"Yu Qingfei is also super 3s?" Wei San saw limited information about him on the Star Network, but it was nothing more than that he was an epoch-making figure, an awesome soldier and master.

Ying Chenghe shook his head: "Not sure, the level of these masters in the Federation is all 3s, but in recent years some people suspect that the level of those masters is different from ours."

"The instrument for testing perception was not invented by Yu Qingfei and that person? How can it be different?"

"Gong Yiliu." Ying Chenghe said.

"Hmm?"

"It's Yu Qingfei and Gong Yiliu." Ying Chenghe explained, "The third-generation instrument currently in use was invented by Gong Yiliu, who is the ancestor of Gong Yijue, a key member of the Imperial Military Academy."

Wei San nodded, vaguely having an idea.

"Maybe because we are both soldiers and masters." Wei San said without hesitation, "I am also an excellent mecha master."

Ying Chenghe smiled and said, "There is a difference. Yu Qingfei was first known to the world as a mecha master, and later it seemed that there was an assassination, and then outsiders discovered that he was still a mecha soldier. As for you, your current identity is a mecha soldier." Wei San thought

: What a pity, if she had money, she would definitely be a mecha master first.
