Further progress has been made in the study of atomic materials, and together with the research in the previous trip, Ruan Lin can conclude that the external composition of three-dimensional graphene is not an undiscovered material, but there is some force on the inside to bring them closer together.

Three-dimensional graphene is only the first layer of its surface material, and there is also an undiscovered material underneath! Its ability to withstand one-third of the speed of light speaks volumes about the material's superiority.

After getting this conclusion, Ruan Lin immediately started the production process, and the three-dimensional graphene he made using chemical vapor deposition technology, although it has a three-dimensional skeleton structure, but to put it bluntly, it is only carbon, not graphene. Specifically, there is a lack of a certain force, and the micro-nano structure is far from being able to support 100% reflectivity, and it is completely unable to integrate with the surrounding dark starry sky like atoms.

Not to mention that this layer of three-dimensional graphene has a thickness the size of a neutron! It's almost like nothing!

Ruan Lin gave up this research for the time being, and he continued to pounce on the parts of the A251.5, its two weapon launches were disassembled separately, and the two weapons it was equipped with were easy to figure out some ways with the current comprehension.

In less than 3 years, according to the ready-made kinetic artillery launchers and Ruan Lin's own understanding, the kinetic artillery was officially developed.

It is a modified version of the electromagnetic railgun, which uses a stronger track and increased electrical energy rationing, and has an initial velocity of 30,000 km/s, which is equivalent to one-tenth of the speed of light. This is much more powerful and accurate than the previous single projectile.

In the following 5 years, Ruan Lin devoted himself to the research and development of the electric field proton cannon, and he is now reincarnated like a starving ghost, with only these scientific and technological knowledge in his eyes.

The electric field proton cannon did not go too far beyond his knowledge, and the principle of the electric field proton cannon was not much different from that of the bomb in the electromagnetic vein. It is emitted by electromagnetic acceleration to form a form of conduction current, mainly for electromagnetic interference.

Ruan Lin also imagined making an electric field ion cannon, but the electric field proton cannon in front of him is more effective, because the proton is lighter, the speed will be faster under the same high power, the current intensity will be greater, and the electromagnetic interference ability will be slightly stronger than that of the ion cannon.

At this time, it was 20 years since he arrived in Amakura Goe, and he also felt that it was time to visit Al.

Once again, he stepped down from the Titan in his mechanical body, and walked towards the foot of the familiar but somewhat unfamiliar mountain.

He shouted directly in front of him, "Al! Where are you? ”

His figure gradually became clearer, he did not jump as before, his pace was extremely slow, his big ears drooped on both sides, and the pure white hair on his body had lost its former luster.

It seems that the lifespan of this race is not long.

He is already in his twilight years, and Ruan Lin's physical appearance is still the same.

His voice sounded extremely old, too: "Hmm... It's been a long time since I've seen you, Ruan Lin, strange tall guy! ”

Al didn't have the same words as he had been.

"yes.. It's been a long time. Ruan Lin was also a little sad at the moment.

He walked in front of Ruan Lin's eyes and tugged at his trouser legs: "Has the enemy outside been defeated by you?" Have you and your people been hurt? ”

"It's been completely wiped out by me, I lied to you in the first place, Al, in fact, I don't have any people."

Ruan Lin leaned down to look, and Al also sat on the ground, looking up and looking at Ruan Lin.

Al coughed twice: "You haven't changed a little bit for so long, it's amazing, I'm about to become the patriarch!" ”

Ruan Lin didn't continue to speak, he crouched down and stroked the top of his head.

His carrier brain began to heat up gradually, and he thought of himself in the age of Earth, because he was so engrossed in his own preferences that he ignored too many things around him, and the friends around him gradually left him.

He thought of Kado and Kaze again, and he didn't know how they were doing now.

Although he himself could not feel the passage of time, Al in front of him was the best witness.

The passage of time had made him grow old, and Ruan Lin felt that the first time he met him seemed like it was just yesterday.

Ruan Lin made up his mind: "For the rest of the time, let me spend the rest of the time with you, and I will let you see the starry sky outside." ”

According to their vocabulary, Ruan Lin combined the word starry sky.

"Starry sky? What is that? I've never heard that word. ”

This time, Ruan Lin took the initiative to lead him to the Titan, where the astronauts tailored for him would be completed.

The Titan's hatch was open, and Al was curious again: "This is your big thing!" Actually, I've wanted to go in and have a look for a long time. ”

Ruan Lin covered his mouth and smiled, and pointed to the sky with his right hand: "Haha, this is my little thing, and the big thing is on it!" ”

The astronaut tailor-made for Al was completed in two hours, and Ruan Lin was helping Al to wear it at this time.

Al asked with joy, "This dress is so heavy!" But it's pretty good, I like it very much, can you give it to me? ”

Ruan Lin nodded: "Of course, this is for you." ”

As Al's donning was completed, Ruan Lin also let WIT steer the Titan to start taking off, and the engines in the rear began to rumble, and Al was startled.

"Hurry up and sit down! Don't get dumped in a minute. Ruan Lin said as he pushed Al into the main control room and secured him to his seat.

The WIT announcement also rang out: "The centrifugal force manufacturing device is operating normally, the ignition time has arrived, and the climb has begun." ”

The next moment, the Titan began to gradually accelerate, and at a distance of 24 kilometers from the surface, it passed through the marshmallow-like clouds, which were the stratosphere of the Tenkura Five.

Al hurriedly unbuckled his seatbelt, and he ran to the porthole on one side.

"We went outside! It's a wonderful feeling, it's a little fluttery! I'm down there! ”

Al watched his surroundings with interest, his eyes wide open, wanting to keep this moment in his mind forever.

At a distance of 30,000 kilometers from the earth's surface, the curvature of the five e-e.

Al pressed his face close to the porthole, and his eyes widened again: "This... Is that where we live? It turned out to be a big round thing! Why is it flat when we look at it, and how can it hang here? Won't it fall? Will we fall one day! It's so dark around it! ”

His words are vividly reflected in this moment, perhaps it is the path of every civilization, and one day they will raise their heads and begin to fantasize about the starry sky in their eyes, and then carefully verify it.

Ruan Lin laughed and explained to Al in extremely simple words.
