As he started to move, “I heard a message the other day that a mecha engineer didn’t kill Star Beasts when collecting materials, but took them while they were alive because that way it’s better quality materials. Star Beasts really only know how to attack humans, and they are undoubtedly harmful, but I hope the students I have taught won’t use this method in the future. It’s not pitying for Star Beasts, but if you do too much of this, you will have psychological problems yourself.”

Yu Qingfei raised his hands, pausing in mid air, his face not too happy, saying, ‘That engineer has gone through such crooked ways. I hope there won’t be such people in the future in the Federation.'”

After that, he didn’t say these things again, simply teaching how to handle materials mixed in weapon metal.

However, Wei San had a premonition that this was the first time that Yu Qingfei had shown such a complex and heavy expression in the teaching video he left behind, and the original loose and spirited expression he had brought precipitated down.

After learning to process materials with Yu Qingfei, she suddenly saw everything disappear and then returned to the empty second floor.

“Wei San, you stayed inside for five hours.” Ying Chenghe looked down at his light brain, as he had just forced Wei San to exit.

At present, among the people at Damocles Military Academy who use this instrument for brain interface learning mechas, the person with the highest authority is Ying Chenghe.

“Really? I don’t remember.” Wei San got off the platform and her legs softened.

Ying Chenghe walked up to hold her and said, “How was your first class?”

“Very good, starting with materials.” Wei San stood in place, her nose bleeding began to flow again, but now she had no waves in her heart and skillfully blocked her nose with a paper towel.

Doctor already said it’s a sign of sensory recovery.

“Materials?” Ying Chenghe was stunned, “Isn’t it starting from learning about the mecha engine?”

This is a teaching video that masters have recorded, set parameters, and imported into the mecha before they died. It looks like it’s one-on-one, but actually everyone is learning the same content.

“It’s not.” Wei San looked at Ying Chenghe, “Didn’t you learn about the materials?”

“Yes, but you started in the wrong order.” Ying Chenghe frowned and glanced back at the machine. “It may be related to you being a super 3S.”

“Yu Qingfei is also a super 3S?” Wei San saw that his information was limited on the star website, but it was just that this was an epoch-making figure, a powerful soldier, engineer, and double major .

Ying Chenghe shook his head and said, “I’m not sure. These masters in the Federation are all levels of 3S, but in recent years, some people suspect that the level of those masters is different from our level division.”

“The instrument for testing perception was not invented by Yu Qingfei and someone else? How could it be different?”

“Gong Yiliu.” Ying Chenghe proclaimed.

“En?”

“It’s Yu Qingfei and Gong Yiliu.” Ying Chenghe explained, “The third generation instrument currently used was invented by Gong Yiliu, who is the ancestor of Gong Yijue, a major member of the Imperial Military Academy.”

Wei San nodded, blurrily remembering a concept.

“Maybe it’s because we are both soldiers and engineer practitioners,” Wei San said unashamedly. “I am also an excellent mecha engineer.”

Ying Chenghe laughed and said, “There is a difference. Yu Qingfei was first known as a mecha engineer by the world, but later it seemed like there was an assassination attempt. As for you, your current identity is a mecha soldier.”

Wei San became thoughtful: Unfortunately, if she had money, she would definitely become an engineer first.
