According to the exam number, Shen Hongfei came to a desk. There's a robot sitting next to it.

"Hello, classmate, please prepare now and start the exam later."

Hearing the robot's words, Shen Hongfei took out the alchemy tools from the storage space, looking like he was ready.

There are nearly 100 people in the examination room, and everyone is ready under the monitoring of robots.

"Bell bell bell ......" rings in the examination room. Candidate No. 797 is asked to start making a cloud powder immediately. ”

Shen Hongfei didn't know the exam questions in advance, and the examiner only told him what materials to bring into the examination room.

Hearing that he wanted to make this unheard of cloud powder, Shen Hongfei was nervous in his heart, but after thinking about it carefully, it was impossible for the school to come up with some unfinished exam questions, and the formula of this cloud powder was very popular.

Sure enough, Shen Hongfei searched the Internet and found a lot of formulas of cloud powder.

Cloud powder is usually used in smoke bombs, stage effects, etc., and is extremely popular, and it is relatively difficult to produce. Also, the freshman year is mainly to learn physical properties, and alchemy is secondary.

After a few glances at the formula of cloud powder, Shen Hongfei was confident, and rubbed his right index finger and thumb, "Whew!" Suddenly, a blue flame appeared, and then slowly approached the underside of the bowl and lit the alchemy furnace.

After the bowl is hot, Shen Hongfei's hand movements are like syllables, rhythmically picking up the materials and putting them into the bowl, stirring while adjusting the temperature, the whole action looks extremely smooth, which is pleasing to the eye.

In just one time, Shen Hongfei successfully made cloud powder.

"Candidate No. 797, do you have to submit your test results?"

"Submit!"

Shen Hongfei poured the cloud powder into the yellow paper and wrapped it and handed it to the robot examiner.

"Candidate No. 797 Exam Result Has Been Successfully Submitted......"

Shen Hongfei looked around, everyone was busy with their own exam questions, and no one had completed their goals yet.

Shen Hongfei stood up lightly and didn't disturb anyone. The human examiners came over to ask, Shen Hongfei only said that he had finished it, and the examiners didn't feel anything, but the other party was lucky, so he let him leave the examination room.

Shen Hongfei, who left the examination room, sent a message to Long Xu, but the other party did not reply for a long time, so Shen Hongfei had to wait.

After waiting for an hour, Long Xu replied to the message. The two agreed to meet at the Guangjia training ground.

Shen Hongfei came to the Guangjia training ground, and Long Xu had been waiting for a long time.

"Xiaofei, do you want to sharpen your gun?"

"Well, I don't know anything about light armor, I hope Brother Long Xu doesn't hide his secrets."

"Well, I can't learn anything in just one night, so I'll teach you about it."

"Thank you, Brother Longxu." Shen Hongfei bent down slightly.

Long Xu laughed and said: "Listen carefully, there are two most important parts of the light armor, one is the hardware, that is, the fuselage, and the other is the light brain, which is the soul of the light armor." ”

"You are studying mechanics, and there is very little knowledge about the light brain, the most important thing is the light armor body."

"After thousands of years of development, the light armor has evolved from an iron shell to a multi-functional body that can fly into the sky. Although there are many types of light armor, there are also similarities. ”

"Most light armors have a total of six engines, one main engine, one secondary engine, and four mounted engines. The main engine is near the cockpit, the secondary engine is in variable position, and the four mounted engines are on the limbs. ”

"Most of the light armor power systems use internal combustion energy, and the auxiliary power system uses cooling energy."

Shen Hongfei listened and picked up the notes to record.

"Do you understand the basics? In fact, this knowledge can be understood through re-knowledge, but then the cognition of light armor will fall into limitations, which is not conducive to future development. ”

Some knowledge can be rediscovered, and some can't, otherwise there will be trouble.

"Well, most of them understand, but I haven't personally manipulated the light armor, and I don't know much about the entire system."

"Hehe, let's go, I'll take you to experience it." Long Xu pulled Shen Hongfei to a light armor about 3 meters high.

It's a humanoid light armor that looks very ordinary, and the weapon configuration is just an alloy knife.

"This is the student's light armor, which is the most basic model, and it is much easier to learn this and then learn something else." Long Xu said.

Long Xu applied to the system for light armor training, and this light armor was unlocked to the outside world.

"Start!" Long Xu suddenly burst into a shout.

Guangjia's eyes suddenly glowed red, and a landing pad quickly landed downward.

Shen Hongfei faintly felt a sense of crisis when the light armor's eyes lit up, and he didn't know whether it was the light armor or the feeling that Long Xu brought him.

"Let's go, let's go up." Long Xu pointed to the landing pad, which could barely stand for two people.

Shen Hongfei stood up, and Long Xu also stood up. The two were very close, smelling Long Xu's strong manly scent, Shen Hongfei somehow felt a little strange in his heart.

Shen Hongfei and Long Xu were huddled on the small landing pad, so close to each other, and both of them looked a little strange.

At this torturous moment, the landing apron finally rose to the position of the cockpit, Long Xu stepped into the cockpit first, and Shen Hongfei followed closely.

There is not much space in the cockpit, and it is inevitable that two people will bump and bump, and gradually Shen Hongfei is becoming more and more embarrassed, but Long Xu does not think too much, he said: "Because of the reason of the light brain, it is actually very simple to drive the light armor." Next, he talked in detail about the details of driving the light armor, Shen Hongfei learned very quickly, and he could make a few simple moves in the huge light armor in a short time.

"Letting the light armor do the action is the easiest operation. Those complicated operations, involving martial arts routines, will be difficult then. For example, the rapid light slash, this is the popularization of the knife technique, and it takes a lot of operations to cast it by the light armor, you can take a look. Long Xu called up a dead target.

Long Xu's hands flew up and down on the light screen, one by one instructions were issued in an orderly manner, Guangjia squatted on his right knee, his left foot slammed on the ground, his right arm was bent and extended, and the alloy knife was instantly untied by it. The light armor almost instantly crossed 30 meters, and Shen Hongfei barely felt much shock, and a 4-meter-high alloy dead target fell down with a bang and was cut in two.

"There are hundreds of moves in the light brain, and these instructions I just gave can actually be simulated by the light brain, and the reason why I want to fine-tune it is because we can't always rely on dead programs when dealing with different enemies. For example, if my right knee squats down more than half a centimeter, the impact will be stronger, so these fine-tuning are necessary. ”

Shen Hongfei nodded to show that he understood, and Long Xu said again: "I have taught you the basics, and the rest is that you are proficient in groping by yourself, but the exam will not be too difficult, and it will not let you drive the light armor to fight with people, you just need to know the basic structure of the light armor." ”

Shen Hongfei nodded and said, "Thank you, Brother Long." Then I'll practice by myself, and you can get busy. ”

"Well, the Dragon War Squad has a party at night, so you don't have to participate, just concentrate on training."
