This room is not even square nor rectangular.

It is a huge oval in shape, in the shape of a ring, and it does not even have a corner.

He was completely confused, and he remembered that the night before, he hadn't quarreled with the Blue Dragon Captain.

They were all sitting there and having dinner together.

Luo Chuan suddenly pulled him to a corner of the bathroom, his face was terrifyingly pale.

"Roland didn't come looking for you?" Luo Chuan asked, his voice was low, and his eyebrows were almost wrinkled.

Nangong Tian forcefully broke away from his hands and asked suspiciously, "Who is Roland?" ”

"Why did she come to me?"

"My sister," Luo Chuan said in a low voice, "it's my sister." ”

"If I hadn't come to you, I guess I would have gone to the headquarters of the undersea school." Luo Chuan's voice trembled a little.

At this time, his heart was full of fear, and he couldn't imagine what Roland would look like when he was injected into Interstellar.

She was his only sister, and he couldn't let her get hurt in any way.

Luo Chuan's neck was injected with an upgraded version of the interstellar pass, and since he was injected with this interstellar pass, he felt that sometimes he was delirious, and even his memory had declined.

Maybe he's just an experiment in an upgraded version of Interstellar Pass.

"I didn't even know you had a sister." Nangong Tian said, scratching his head, a little embarrassed, "Where is she now?" ”

Luo Chuan's face was red to his neck, he took a deep breath, turned his head to look at Nangong Tian, his eyes were wide open, he wanted to say something, say something important.

"I don't know if I should trust you or not." Luo Chuan said that he felt that he was making a bet, and this bet was Nangong Tian, Nangong Tian had a stubborn personality, but he felt that Nangong Tian's nature was not bad, "Save my sister." ”

"What?" Nangong Tian almost jumped up from the ground, and he twisted Luo Chuan's face with his hand to make sure he didn't hear it wrong, "I said Xiaochuan, where is your sister?" Nangong Tian put his hands in his pockets, doing so whenever he wanted to concentrate, "Also, why should I help you?" ”

Luo Chuan stood up straight, since Nangong Tian asked so, he must have planned to help him.

"It's very simple, I feel like she's in the undersea school headquarters." Luo Chuan said, he tried his best to sense Roland's breath with his head, but he couldn't feel anything, "She didn't contact me, I think something must have happened to her." ”

"If it's Professor Nangong, it's fine, but if Teacher Panda ......," Luo Chuan said, with fear in his eyes, "I'm not at ease." ”

"Okay." Nangong Tian said, Luo Chuan has never asked him for anything, this is the first time, although he doesn't know what happened, he still has to agree, after all, if he doesn't agree, who can really help Luo Chuan? "You tell me what to do."

Then, Luo Chuan told Nangong Tian about his plan, and there was a scene where Nangong Tian and the Qinglong senior quarreled and were expelled from the Qinglong Action Team.

Nangong Tian stood in this oval room, carefully looking at everything in this room.

Luo Chuan's sister Bacheng is here.

But here except for those human embryos that have lost their vitality, it is the pale body of the white tiger.

Nangong Tian suddenly felt that he was weak.

It's true.

He couldn't even find a girl.

Eros.

Underground trenches.

Luo Chuan took out a diamond blade from his pocket and scratched it on the transparent wall a few more times.

The walls are still moving.

"Damn it." Luo Chuan shouted, his face flushed, "I just can't draw it." ”

Originally, Luo Chuan planned to use these graphene to make a solar power supply system and let the spacecraft restart.

Now it seems that he simply can't cut a piece of graphene out of a transparent wall.

Even if it's a microcubic meter.

Luo Chuan was already out of breath, and he was very tired.

What can be done to get tired.

Think of Suzaku who were still lying in the spaceship, Qinglong and Xuanwu, they were lying there quietly, not even breathing.

What's the point of being a little tired?

Luo Chuan's brain has already begun to search for all the ways to cut graphene.

"The common methods for preparing graphene are mechanical exfoliation, redox method, SiC epitaxial growth method and chemical vapor deposition method.

The mechanical stripping method is a method that uses the friction and relative motion between the object and graphene to obtain a thin layer of graphene material. This method is simple to operate, and the graphene obtained usually maintains an intact crystal structure, but the resulting flakes are small and the production efficiency is low.

The redox method is a method that obtains graphene by oxidizing graphite, increasing the spacing between graphite layers, separating it by physical methods, and finally reducing it by chemical method. This method is simple to operate and has a high yield, but the quality of the product is low.

The SiC epitaxy method is to sublimate the silicon atoms from the material in the high-temperature environment of ultra-high vacuum, and the remaining C atoms are reconstituted in the form of self-organization, so as to obtain graphene based on SiC substrate. This method can obtain high-quality graphene, but this method has high requirements for equipment.

CVD is currently the most promising method for industrializing the preparation of high-quality, large-area graphene. The graphene prepared by this method has the characteristics of large area and high quality, but the cost is high at this stage, and the process conditions need to be further improved. ”

Luo Chuan struggled to recall the words in the book "Preparation of Graphene".

The book was seen in the Faculty Museum of History, and when he saw it, it was already covered in dust.

He thought he would never use the words in the book, or even just a noun.

But now he wanted to recall every word in the book, even every punctuation mark.

"I have to remember." Luo Chuan's forehead was already covered with beads of sweat, and his brain was running rapidly, "How is graphene prepared?" ”

His palms were also covered with sweat.

Luo Chuan closed his eyes and concentrated on recalling the words on the book.

However, an image appeared in his mind that worried him.

The picture shows a girl lying on a cold laboratory table with a clear plastic tube inserted all over her body.

Her lips were purple, her hair was about to fall out, and her eyes were closed.

"Ah......" Luo Chuan opened his eyes, his vision blurred, and he couldn't remember the face of the girl in the picture.

However, a dull pain ignited in my heart.

"Nangong Tian," Luo Chuan secretly exclaimed, "Have you found my sister?" ”

Thinking of this, something called sadness welled up in Luo Chuan's chest, he felt a fire all over his body, and there was only one thing in his mind, that is, to hurry back to the core planet, and he slapped the wall violently.

In an instant, the shock wave rippled through the entire low trench.

Luo Chuan tried his best to calm down, but no matter how hard he tried, he couldn't calm down.

The whole planet of Eros trembled.
