After seeing off Mi Jiufeng, Yunyang immediately shouted that he would return to Earth, and he didn't want to stay for a long time.

As for those invitation letters from the Superpower School, Yun Yang threw them into the garbage and poked them. What a joke, Yun Yang wanted to return to work at Ye Shen, so how could he have time to go to other planets?

Mi Jian had no choice but to ask his subordinates to prepare his starship and return immediately with Yun Yang.

Mi Jian's ship belongs to the Galaxy Hound-class frigate, about 185 meters long, equipped with four light ion rapid-fire cannons and a curve-speed transition engine, which belongs to the frigate with relatively weak combat power.

It was the first time that Yunyang had come into contact with a warship outside the Night God, so he asked Mi Jian to take him around everywhere.

After walking around, Yunyang found that the ship's defense and firepower were too poor, which was very different from the image of the warship in his mind.

"What's so strange about this?" Mi Jian spread his arms and said, "My ship is a civilian frigate, not a model used by the military, so there is not much firepower."

"But look, I have a lot of living facilities here, including a restaurant, kitchen, living room, a bathroom with massage function, a study, a cloakroom. Staying on a boat is more comfortable than staying in a hotel."

Yun Yang disagreed and said, "If I were you, I would never have installed a jacuzzi bathtub. It would be a waste of space. By the way, how much is this small frigate worth? How much is a military-level one?"

Mi Jian didn't understand these, so he asked Captain Yue Wei to answer.

Yue Wei said proudly: "This ship is priced at 65 million Galaxy dollars normally, and the military model is more expensive. After all, the military model is equipped with more advanced fire control radar and some other weapons and equipment, and the lowest price is 100 million Galaxy dollars."

"So expensive." Yun Yang frowned and said, "Does the military-type fire control system use optical radar, gravitational radar, or multiple composite radar?"

"Often optical radars are used, and the multi-radar system is more expensive." Yue Wei replied.

"What about the engine? Can vector acceleration reach 15mn?" Yun Yang asked again.

This question is very profound. Yue Wei was stunned and said with a serious expression: "If you can't get there, you are mostly equipped with a 1 to 12mn warp engine. After all, the engines used by the escort-class warships are small in size and rarely can reach 15mn unless a spiral energy accelerator is installed."

"No, that will cause the starship centrifugal speed to decrease and the warship will become inflexible." Yun Yang thought for a while and said, "It is better to install two jet channels in the jet system, which will be more efficient."

"You are right. Improving energy supply is worse than improving the jet system. When I was in the Captain's Academy, my tutor also thought so. The only problem is that after the jet system is improved, the engine's thermal control will be more difficult." Yue Wei replied seriously.

Yun Yang nodded, "Thermal control can also be improved. Just increase the thermal efficiency by installing an energy circuit with higher pressure."

Yue Wei was stunned and said in surprise: "This idea is good, the thermal efficiency has improved. Even if the injection system adds two units, it will not cause the attenuation caused by the thermal accumulation effect. Why didn't I expect it!"

"Mr. Yun, increase the thrust of the warp engine to 15mn, so that the engine loss rate will be increased by at least 15%. How to solve this problem?"

Yue Wei originally looked down on Yunyang. After all, Yunyang comes from a backward area like the earth, so he thinks that Yunyang cannot understand such complex starship technology.

But now he suddenly realized that Yun Yang not only understood starships, but also knew very well, and was more proficient than him, a top student who graduated from Captain Academy. So when he spoke again, he unknowingly used a respectful word to Yun Yang and called him Mr. Yun.

Yun Yang smiled slightly and said, "Warships are used to fight. Strengthening the maximum power of the engine will indeed shorten the engine's life, but you think, if you really encounter battles, higher maneuverability can help the warship survive on the battlefield. Is it important to survive, or is it important to let the engine work for ten or eight more years?"

"Of course it's important to survive!" Yue Wei said excitedly: "Mr. Yun, I understand what you mean. The engine can be pre-modified, but it may not be put into use immediately. This is like an overload system. At critical moments, sacrificing the life of the engine in exchange for higher maneuverability!"

Yun Yang nodded: "That's what I mean. As a combat ship, a device to improve performance can be used without it, but it cannot be without it."

"Mr. Yun, which Starship Academy did you graduate from?" Yue Wei asked curiously with admiration.

Yun Yang was stunned, "I have never been to Starship Academy."

"Who are you?"

“I’m homeschooling.”

Yunyang was reading a book in his room. Mi Jian took a letter and found him, threw the envelope on the table, sighed and said, "Look, this is Yue Wei's resignation letter."

Yun Yang was stunned, picked up the envelope, and asked in confusion: "Why did he resign?"

Mi Jian said laughing and crying: "Didn't you force me? Yue Wei is an outstanding student at Starship Academy. Because our Mi family once helped his grandfather, he gave up the opportunity to serve the military and came to be the captain of me."

"But you, you've destroyed Mi Jian's self-confidence in one go. He graduated from a professional class, in the end, is not as good as your homeschooling wild path. How can Yue Wei be with such a strong person?"

"He and I resigned and wanted to go back to the college to continue their studies. He also vowed that he would never come back if he didn't learn some real skills."

Yun Yang was speechless. He opened the envelope and saw that Yue Wei was physically and mentally frustrated. He felt that he was not qualified to be the captain and must go back to the academy to continue studying.

Yun Yang frowned and threw down the envelope and said, "I will persuade him to not compete with me in this wild way. I am just a verbal trick, but I don't know anything."

"If you don't understand, you can quit what Yue Wei said. If you really understand, Yue Wei will hang himself in shame?" Mi Jian curled his lips and said, "My good brother, I know you are amazing, but you still have to be more at ease in the future. Not everyone can compete with you."

After having that conversation with his father, Mi Jian concluded that behind Yunyang there must be a paradise who is far above the Grand Master, so he was no longer surprised by Yunyang's doing anything and felt it was right.

"By the way, why are you so concerned about the warship? Is it because you are worried about the war outside the Galaxy?" Mi Jian asked curiously as soon as the topic changed.

Yun Yang nodded, "Yes, the earth is only two hours a day away from the border. I am afraid that the war will affect my hometown, so it will be troublesome."

"Not it?" Mi Jian said: "I heard from my father that there have always been ghost clans, but the Milky Way has never lost. They have never entered human territory once, and all wars broke out outside the territory."

Yun Yang looked out the window and said with a heavy look: "I'm not afraid of ten thousand, I'm afraid of anything."

After a few days of voyage, Yunyang finally ended his first space trip in his life and returned to his hometown, Earth.

Standing in the command room, Yun Yang faced the huge porthole and said excitedly to Mi Jian: "You will see my hometown soon. Although I haven't been to many places, I think there should be few planets in the Milky Way more beautiful than the Earth."

"Come on." Mi Jian said disapprovingly: "The earth is good all day long, the earth is good, and my ears are almost calloused by your mouth. Who doesn't say that my hometown is good? I also think my hometown can rank first in the Milky Way."

Yun Yang ignored Mi Jian and looked out the window in distractedly.

Swish ~

The starship finally flew out of the transition wormhole and returned to the solar system.

The blue planet was clearly in front of him, but Yun Yang was stunned and could not believe what he saw with his eyes.

"What the hell is this?" Yun Yang said with his mouth wide open.
