In a blink of an eye, two years are about to pass. Within forty days, he will leave this familiar office and enter his second hibernation...

Zhang Yuan recalled the little things over the past two years, from the initial adaptation to the later discomfort...

He has learned a lot of new knowledge, especially new knowledge in mathematics, new civilization history and industrial science, and is still looking forward to the future.

At present, the most cutting-edge direction of Earth civilization is the research on space weapons, including lasers, electromagnetic cannons, ion cannons, etc.

Since the existence of powerful alien civilizations has been observed, no matter how weak humans are, they still need to study these weapons. It is definitely a fool to grasp their own destiny in the moral qualities of aliens.

There is no need to say more about lasers. The development of condensed matter physics has made the power of lasers become increasingly larger.

However, laser weapons have their own limitations.

After a laser weapon hits the target, the ultra-high temperature generated will cause various metals to rapidly plasma. These high-temperature plasmas can absorb a large amount of energy in a secondary manner and prevent the laser from further destruction. Therefore, the lethality of this weapon is not strong enough.

The electromagnetic cannon is a kinetic energy killing weapon made using electromagnetic emission technology. According to the current electromagnetic acceleration technology, it can accelerate bullets the same size as soybean to one-tenth of the speed of light.

One-tenth of the speed of light, 30,000 kilometers per second, is an amazing number.

Although it is still as slow as a snail compared to the vastness of the universe...

Ion cannons are also a kinetic energy weapon, but the bullets in them have become charged particles such as protons, just like turning a hasron collider into a weapon.

The speed of the ion cannon can be higher, and in theory it can reach more than 90% of the speed of light.

One of the branches, the research on proton cannons, has reached a relatively mature stage, including various materials and weapon structures. The Deep Space Foundation sent some of its papers to the spacecraft.

Zhang Yuan didn't know how the Deep Space Foundation got this high-level military secret, but he sent it to the Earth Age anyway.

"Perhaps, there are some political big names inside the foundation who are secretly supporting it."

With his authority as a 16-level staff member, you can read at will.

In addition to proton cannons, there is also a more advanced research direction for ion cannons, a thing called "helium hydrogen ion cannon".

The chemical formula of helium hydrogen is HeH, which is a positively charged ion.

This thing is known as the strongest acid in the universe. It can react chemically with almost anything. After hitting the target, it will not only generate kinetic energy and electromagnetic damage, but also corrode surrounding matter. In short, it can be much more powerful than proton cannons.

But because of this, HeH cannot be prepared in a condensed state, because it will cause it to interact with anions, molecules, and atoms, so there is still a long way to go in terms of manufacturing and reserves.

call……

Zhang Yuan felt a little excited after breathing a relaxed breath and putting down these information.

What he likes most is large industry and large production, and he wishes he could immediately arrive at the future planet and engage in research in this area.

More than ten hours of self-study a day is not in vain. It is a great honor that he can understand some cutting-edge sciences in this new era again...

"Hello, Mr. Zhang." A voice rang in his ears. A young man named Zhao Chao was succeeding him.

The young man had just woken up from hibernation, with a look of trepidation. He was trying to muster up the courage to face the facts that had happened.

Zhang Yuan sighed secretly, just like Fang Yuhao received him at the time, he received the poor boy very carefully and shook hands with him.

Immediately afterwards, he said the same thing: "Mr. Zhao, the psychological counseling room is there. Perhaps, you can take a break for a while and wait until your mood recovers before taking over my job..."

"I have a few comedy movies here to recommend you, including the Westward Journey series, the Dragon Ball series, and the Pirate King series..."

...

More than a month later.

After step-by-step guidance, the successor Zhao Chao has mastered all the work and his emotions have gradually stabilized.

In this way, he could leave with peace of mind.

On this day, Zhang Yuan was saying his final farewell to his good friend Lin Xuanxuan.

"…Hidding is really a good thing! When I wake up, I can see the latest developments of human civilization and learn new knowledge. I don't know if the helium hydrogen ion can be successfully studied..."

Speaking of which, Zhang Yuan felt a sense of shame because he was just learning and did not explore nature, as if he was just lazy...

"What's so ashamed of this? It's already very good to learn the most in two years." Lin Xuanxuan came out of the room, holding a small plate in her hand, and putting a few golden tortillas on it.

"It's just a small part of the cutting-edge content." Zhang Yuan said ashamed.

Lin Xuanxuan just forced a smile, not looking very happy. However, she still squeezed out a smile: "Try my newly developed pancakes! Bake in the oven!"

After taking care of each other for a while, the two of them have become very familiar with each other. In addition, in this closed environment, it becomes very difficult to not get along well with each other.

This girl is very good at cooking, and all kinds of strange foods are emerging one after another. Under such poor supplies, being able to cook delicious food is an amazing skill.

Lin Xuanxuan sat opposite him, watching Zhang Yuan taste it in small mouth, and her mood was a little complicated. The batches of hibernation were planned in a coordinated manner. Usually, the chances of the two meeting again when they wake up are really small.

She began to try to find some topics: "Well... what about the future of human beings? You are not worried about it? Didn't it mean that robot raising has been tried in some places?"

Zhang Yuan smiled and said, "Since what has happened, what are you still worried about? I can't help... The captain and others are not worried, they want me to worry... What I can do now can be donated at most. Donating this amount is really out of money."

Lin Xuanxuan held her chin with one hand and looked at him: "It's more than 300 billion! It's not more than 300 yuan, why are you so generous? Why don't you don't it to me and let me experience the feeling of a world-class rich man, and you can keep a lot of young and handsome guys!"
