Wei San went to the ground floor, not only to repair her mecha, but also for the materials sent by ‘I have money’. She left Sadu star in a hurry last time to go to the competition, and she didn’t have time to see the S-grade materials.

“I haven’t seen you for a long time.” The shopkeeper pulled something out for her. “Did you go to watch the competition?”

“Is to attend the competition.” Wei San moved the engine to the console.

“This is S-grade material, can you use it?” the shopkeeper asked her.

Wei San held her hands on the console, looked at the shopkeeper carefully and nodded at the door.

“……”

The shopkeeper stepped back and “snapped” the door, the sound carried a little anger.

This is not the end. The shopkeeper went to the transparent glass and swiped down the curtain.

Wei San: “?” When were the curtains installed outside.

She refocused her attention on the S-grade engine. As long as these parts were not used to build the mecha, they would not be damaged just by looking at them.

Compared with the A-grade mecha engine, the S-grade engine is integrated. At first glance, it can’t be disassembled. The smooth lines are wrapped with metal inside the parts. Every undulation is appropriate. The surface is more like a work of art.

After studying for a long time, Wei San found that there was really no tool to open the engine and see the structure inside. She sent a message to Ying Chenghe and asked him how to use tools to repair a S-grade engine.

Master Chenghe: [Perception, the perception of the robot division can be used as a tool. As long as the control ability is accurate enough, this ability typically can not be achieved by soldiers or commanders.]

So that’s how it is. Wei San looked at the engine on the console and moved her hand slightly.

Master Chenghe: [But it’s better for A-grade mechanics to not touch it, even if it’s the S-grade parts. Where are you? Why are you asking this question.]

Ying Chenghe in the drill field looked at his light brain and sent a message over. Wei San was a soldier of grade A mechas. It was enough to learn to transform grade A mechas by herself. Skipping a grade would only hurt her.

Begging secretly: [came out to play and suddenly thought about asking.]

Wei San turned off her light brain, looked at the engine on the console, put her hands on the table, and unconsciously lit it.

This feeling is like a hungry man, who has a delicious dish in front of him, but it is sealed by the glass cover and cannot be opened at all.

She wants to see the structure inside.

“Shit!”

Wei San covers her nose, which was a familiar bad feeling.

She hasn’t started to move yet, but she can’t even think about it?

She even stopped looking at the engine. Wei San went out with the blood in her nose in one hand. She held it in one hand and went out to find the main paper in the store.

“Is your internal fire too big?” The shopkeeper drew paper for her, “or are you too excited?”

Wei San plugged her nose and said, “Low perception, thinking of S grade.”

She handed the engine to the shopkeeper for safekeeping: “Put it here first.”

The shopkeeper only reflected on the meaning of that sentence for a long time after she walked away. He looked puzzled and said, “Do you want to forcibly open the S-grade engine?”

After Wei San came out of the Underground Factor, she went to Damocles Military Academy. The physical objects could not be removed or touched, but she could always study books.

School has already started, and Wei San was recognized by other students when she entered. She greeted people all along the way and finally came to the place where the books of Yu Qingfei were collected.

She picked a dozen books from the bookshelf and stuffed them all into her bag. Then Wei San rushed to the drill field.

……

Sadu star’s environment is dry, and many places around it are close to the boundless desert. The drill field is set up near the desert. There are frequent sandstorms, which have a great impact on the vision and performance of the mechas. At present, apart from the physical training of individual soldiers, the mecha engineers are also modifying their own team’s mechas day and night.
