"Am I disturbing your rest?"

"I didn't expect you to sleep so early today......

The room was pitch black, and he couldn't see why, but Tang Yun had already figured out his sloppy roommate. The moment I opened the door, the smell of second-hand smoke that filled the room proved the existence of the other party.

But Tang Yun was very glad that there was no smell of rancid watermelon, rotten banana or wine in the dormitory today, but there was a faint fragrance.

It's really weird, this thing is sprayed with perfume? Tang Yun muttered in his heart and turned on the lamp on his desk.

In order not to disturb the rest of his roommates, he did not turn on the ceiling light in the dormitory. In fact, Tang Yun, a guy who cares a lot about other people's feelings, has obsessive-compulsive disorder, loves cleanliness, and is always a kind of faceless guy is definitely a model roommate.

While saying sorry words in his mouth, Tang Yun packed up the new books that Senior Sister Nie Fan had borrowed from him and prepared the materials to be used in class tomorrow. Since this roommate has to go to bed early and get up early for the first time, he is too lazy to stay up late to read books and affect others.

Seeing that the other party didn't reply, Tang Yun turned his head and looked. Under the dim lamp, Tang Yun's brows furrowed.

"It's so hot, what are you doing with a big quilt?"

"I'm cold!"

Du Feng's tone was still graceful, with the unique accent of Juguxing's south. Tang Yun didn't bother to pay attention to him, took off his coat and scraped the oil stains on the training vest with his fingers and was about to go to the bathroom to take a bath, but Du Feng spoke again.

"Brothers......

"Huh?" Tang Yun was a little surprised, "Why didn't you call me a little white face this time?" ”

"This ......"

"Can you go out for a walk? I owe you a big favor! ”

"What? Go out for a walk in the middle of the night......" Tang Yun turned his head again to look over, but he froze suddenly. Because he looked more carefully this time than before, Tang Yun found that the big quilt covered by Du Feng was a little inappropriate, and after a while, a beautiful girl's face was exposed from behind the quilt.

His face was flushed, and there were beads of sweat on the tip of his nose, revealing an indescribable shyness against the background of the warm yellow lamp.

"Hello classmates!"

"Oh...... Well...... Hello, hello...... That...... I? ”

"What am I? Hurry up and go out and let me do something!" Du Feng said impatiently, "Isn't it okay if I owe you a favor?" ”

"Oh......"

"Okay."

......

......

"Damn, it's spring!"

"Everything is coming back to life, isn't it?"

"It's going to be spring, isn't it?"

Tang Yun walked reluctantly, inexplicably, and lonely alone in the campus of Songyan University in the Northern Regions, scolding silently in his heart while strolling around.

scolded the Wangcai who "rode" a little wild dog into the woods, scolded the roommate who brought the girl back to the dormitory and harmed his "homeless", and scolded the young classmates who were falling in love on the campus benches, beside the pine trees, and in front of the steps.

At the same time, the young man's "spring heart" in Tang Yun's heart also began to ripple.

Qin Shuiyan and Du Run's faces swept through his heart in turn, and even the touch of Ye Xiaoxuan's body contact when he was coquettish with his arm came out of his memory, causing an inexplicable "throbbing" in his heart.

"Alas......"

"Am I also in trouble......

"After finishing this week's class, let's go find the water goose......" Tang Yun glanced at the young couple kissing under a pine tree, and subconsciously licked his lips.

After realizing his gaffe, Tang Yun sighed, took out a cigarette and took two puffs, then breathed the grass-scented spring breeze, counted the warm street lamps in the campus, looked at the bright and dark high-rise buildings on both sides of the road, and felt the hormones burning in his body...... His steps became slower and slower, and he walked into the distance.

......

When Tang Yun, who was distracted, stopped his heart, he found that he had come to the towering building of the School of Mechanical Engineering again.

"I really have nowhere to go......"

Tang Yun scratched his head, and suddenly found that the small factory on the outskirts of the city had become his home, and I have to say that the sense of belonging is sometimes quite interesting.

It's almost eleven o'clock at the moment, and the lights are basically dark in the entire school building. You must know that the dormitory teachers in the other dormitories of Songyan University in the Northern Regions are not as good at talking as the dormitory teachers in Yucai's apartment, and if you come back after eleven o'clock, you will be considered late, and you will be deducted credits if you have too many times.

Tang Yun rubbed his chin helplessly, he didn't know if Du Feng's kid had "finished his work" at this time, he couldn't be a lonely ghost in this place for a night. At this moment, Tang Yun found that the laboratories on the first and second floors of the teaching building were still lit with a few lights.

Tang Yun leaned over boredly and walked through the window to watch the excitement. Sure enough, there are mechanical laboratories, civil engineering laboratories, optical laboratories...... Of course, there is also a photostructure laboratory.

Seeing that a young teacher inside was concentrating on constructing some kind of crystallization with a structure that Tang Yun had never seen before, Tang Yun couldn't help but stop. It didn't take long for Tang Yun to shake his head after all, because he had already seen several flaws in the structure.

There is no doubt that the collection of energy nodes that make up this crystal will definitely collapse during the "solidification" step, and there is still a gap between this young teacher's skills and his own.

Having said that, Tang Yun still didn't leave.

Technically, it's not much to look at, but it's still interesting for this teacher to tinker with something.

The energy body as a whole was a gray color, and it was a patchwork of different shapes, in short, the shape looked like an ancient piece of armor.

Tang Yun had never heard of anyone who had ever made such a "retro" and interesting defensive energy body, not to mention whether it was suitable for actual combat, but simply said that the look and feel of this shape had a little bit of literary feelings. Suddenly, Tang Yun suddenly understood the meaning of this crystal!

The solid-state energy that has existed for a long time is attached to the surface of the mecha in the form of armor, so can't the heavy metal armor on the mecha be replaced by the energy body released by the crystal?

This will drastically reduce the weight of the mech, increasing the speed, maneuverability, and athleticism of the mech! And when transporting, it greatly reduces the difficulty and cost of transportation, what a good idea!
