"He's awake!"

"How are you feeling right now?"

"Is the mission accomplished?"

"How much is this?"

"Can you hear us?"

“......”

In the noisy voice, Zhao Siyuan's eyes gradually focused, he was in a trance for a few seconds, and then pushed away the medical staff's hand and sat up with his body propped up.

"Wait a minute, let me be quiet."

He said, holding his head.

Tu Guangyun waved his hand silently, signaling everyone to be quiet.

He walked over to Jack.

"When you first had a spiritual connection with Ava, did you wake up like this?"

Tu Guangyun said with concern.

Jack nodded, and he said, "As long as you are conscious, it's fine, and the confusion of the brain is because I just got out of Ava's consciousness and suddenly returned to my small body from such a great spirit, and I have a sense of dislocation." ”

Hearing Jack say this, Tu Guangyun was relieved.

Now there is only one question left.

Is Ava willing to help another earth solve environmental pollution?

Tu Guangyun looked at the watch and waited.

After about a quarter of an hour, Zhao Siyuan finally relieved himself and could barely communicate.

Tu Guangyun asked, "How are you?" ”

"I'm fine." Zhao Siyuan muttered, "It's so shocking, the gap between us and Ava is countless times bigger than the gap between ants and us, Ava is so great!" ”

"He is so great!"

"I understand why Jack betrayed the RDA!"

Tu Guangyun frowned slightly.

"I'm not brainwashed!"

Zhao Siyuan seemed to guess what Tu Guangyun was thinking, and he emphasized excitedly.

Tu Guangyun shrugged his shoulders.

He thought to himself that the people who were brainwashed said that they had not been brainwashed, and he must arrange a psychological test for Zhao Siyuan after he went back this time, regardless of whether Zhao Siyuan was happy or not.

Zhao Siyuan said excitedly: "I can't remember what I saw, but I remember that those scenes merged into a colorful silk ribbon, wrapped in me and drifting in a long, long river. ”

"It's a wonderful feeling!"

Zhao Siyuan said incoherently: "It's like a baby in its mother's amniotic fluid, that's right, that's what it feels like!" ”

"You should experience it too!"

"Once you've experienced it, you'll know how I feel!"

"Haha! Hahaha! ”

The more Zhao Siyuan spoke, the more excited he became, and his tone became higher and higher.

Tu Guangyun's eyebrows tightened, he grabbed Zhao Siyuan's hand suddenly, and shouted loudly: "Calm down!" ”

Zhao Siyuan was stunned.

Tu Guangyun turned to Jack and asked, "Is this normal?" ”

Jack pursed his lips and said uncertainly, "It should be considered normal, it has something to do with his personality, is he an avid science enthusiast?" ”

"If so, it's not surprising."

Avid science enthusiasts......

Tu Guangyun recalled for a moment, then took out his tablet and inquired about Zhao Siyuan's personal file.

He read it word by word, and finally found this evaluation in the remarks column - Zhao Siyuan has an extraordinary love for his subject, even better than his family.

Mouthful

But after I go back, I still have to do a psychological test.

Tu Guangyun asked Zhao Siyuan, "Don't talk about your feelings, let's talk about the mission, have you contacted Ava, did he agree?" ”

Zhao Siyuan was silent for two seconds and then said, "I didn't see Ava, but I did see Dr. Grace." ”

Dr. Grace is a plot character in the movie that Ava absorbs.

"She said Ava was willing to help us."

"But Ava needs us to send a Na'vi to that earth, and to sow some seeds of Pandora's plants on that earth."

Tu Guangyun asked while recording, "Did Dr. Grace say which seeds of Pandora plants to sow?" ”

Zhao Siyuan shook his head.

"In that case, let's report to the above."

......

"Eight hundred and twenty-five planetary engines have been converted into antimatter factories."

"The renovation work is still ongoing."

"It is expected that within a year at the latest, we will be able to convert all the planned 5,000 planetary engines into antimatter factories."

The scientific advisor is reporting to Hao Xiaoxi.

There are three ways to get antimatter.

The first is to use the Large Particle Collider, which accelerates microscopic particles to near the speed of light, and then uses those microscopic particles to hit other microscopic particles.

After impact, some new particles are produced, which contain very rare antimatter particles.

This method was commonly used a few decades ago.

At that time, mankind had just discovered the existence of antimatter, and there was no breakthrough in nuclear fusion technology, so they could only use the large particle collider to prepare some anti-hydrogen nuclei and anti-helium nuclei in small quantities in the laboratory, mainly for scientific research.

The second is to collect free natural antimatter particles in the universe, but this collection method is outrageously inefficient, because antimatter naturally annihilates with positive matter, and there are very few naturally occurring antimatter particles in the universe.

There may be natural sources of antimatter in the universe, but humanity is not sure where these sources are.

Only when these sources of antimatter are found will the collection of natural antimatter become mainstream.

The third is to use the near-infinite energy source of nuclear fusion reactions to produce antimatter through a series of complex equations such as the CNO cycle.

This route consumes the most energy.

However, as long as the energy consumption needs are met, antimatter can be prepared on a large scale, so this approach is the mainstream way for interstellar civilizations to prepare antimatter.

Planetary engines are very large fusion reactors.

Today, when the Move Mountains project is no longer needed, scientists can just use planetary engines as factories to produce antimatter.

Of course, not all planetary engines will turn into antimatter factories.

The Earth's rotation is now being restored, all steering engines are working, and some of the propulsion engines are being retained in order to cope with a possible second wormhole shuttle in the future.

Hao Xiaoxi put down the pen in her hand, and she asked: "What about the output, how often can we save enough antimatter to go to the solar system, and how much reserve do we have now?" ”

Without thinking, the scientific advisor replied, "If our ship is the size of the Star, we would have enough reserves to meet the round-trip needs of eleven ships." ”

After a pause, he continued, "But there may be forced acceleration and deceleration during the process, such as crossing the asteroid belt, so if you want to depart in the next few days, I recommend that you don't have more than three ships." ”

In an empty universe, acceleration and deceleration both consume the same amount of fuel.

If you accelerate and decelerate multiple times, the fuel that would have been enough for a round trip may be exhausted on the way to the solar system.

Hao Xiaoxi nodded slowly.

She was concerned about this because the coalition government was discussing a bilateral interview with the government of Avatar Earth (later known as the Avatar government for short).

Each side is preparing to send a team to the other party's planet to investigate.
