Yun Yi thought about it and thought that the first-level civilization could only move in his own galaxy, with a range of no more than one light year, and the ion engine could only reach the highest speed of sub-light speed. He was unwilling to have the century-old light speed and warp engine that Chuji Level 3 civilization had and used it to allow the people to travel interstellarly. There is indeed no place for these products to be used.

When he thought of this, he was in a little conflicted mood. He seemed to have less fun when opening the plug-in too much. He used to look forward to the emergence of various new technologies every time he upgraded, but now he has no feeling, because many technologies were eliminated as soon as they appeared. The reality is so speechless. Of course, it is very happy to come back to his senses. At least the empire has a bright future, at least the result is good.

"Now, a lot of space for transport spacecraft can be saved. The emergence of primary aerospace technology in the synthesis era has allowed the empire's black technology warehouse to be built outside the starry sky. There is no need to use transport ships to transport minerals. Except for precious minerals that have not appeared in the system list, such as dark gold, star set, glazed gold and other precious metals, you must wait until the empire system enters the first-level civilization before the empire system can transform the black technology warehouse owned by the empire system."

Zero once again told Yun Yi a big change in the system. At that time, Yun Yi thought that mining in the solar system could also use the system's black technology warehouse, but the result was very disappointing. Now that the emergence of aerospace technology has been realized, it is not too late, which makes him happy. The savings of transport spacecraft have allowed shipbuilding factories to invest more production capacity in other directions of construction. Since the system's black technology warehouse can play a role in space, I guess the mining device can play a role, right? You only need to send a small number of intelligent robots to settle in to continuously mine the minerals needed for the empire.

"It is best not to convert precious minerals into system resources now. That is too wasteful. You need to use as much as you need. Others are stored in the form of metals. What you need now is to vigorously mine the basic minerals into system resources, and the more you need, the better. I believe that after entering the first-level civilization, the imperial system will change a lot."

Chu Ji also reminded that she didn't know much about the system at that time, and Emperor Haoji did not tell her the habit, and she did not put her in the control room like Yun Yi. She could understand everything she could know, and she was still very grateful for Yun Yi's trust.

The empire has entered the synthesis era, and will stay in this era for a long time beyond imagination. Yun Yi is already ready. As for interstellar colonization, it will definitely be planned slowly based on the development of the empire's population. All the star fields around the solar system have been designated by him as the territory of his empire until the interstellar channel of Cangheng. If there is a good result in exploration, the territory of the empire may expand along the earrings' spiral arms toward the center of the silver, but it is unlikely to think about it. This will take too long. Even if the empire is occupied, there is no enough life stars in the entire territory. According to Chu Ji, Cang

There are not many interstellar life among all the galaxies around the solar system, and they are located remotely and have not developed many intelligent civilizations. Even if civilization is developed, everything is based on the interests of the empire. Except for a few peaceful alien races, the empire does not need intelligent life that is not humans mixed in the empire's nations. Just like other advanced civilizations in the universe, the races in their empires are also very simple. This is determined by the overall environment of the universe. No one is willing to classify the future of an alien that is uncertain whether it is the same as his own nation and treats it equally. Other civilizations cannot do it, and Yun Yi cannot do it.

Of course, if the elves in Xiang Tiansheng Empire can do it, this race nature will make them dislike fighting. Yun Yi doesn't mind that there are such a group of races in his empire that are indifferent to the world but can make great contributions to the development of the empire. If possible, it will be difficult to kill other alien civilizations with his personality, but the cruel reality of the universe has to let him do this, unless the empire stops and hides in a corner of the Milky Way.

Looking at the number of people displayed by the Empire on the control screen, Yun Yi was a little helpless. Although the increase in such a long time can be said to be very fast, the number that has just reached 2 billion is really insignificant for an interstellar civilization that is about to enter the universe and starry sky. Although the people of the Empire can increase the population of the Empire and add children to their families as long as they are willing. They are all young enough now, but they will not force others to do this, right? Yun Yi has not yet such a habit.

Chu Ji looked at Yun Yi staring at the control screen and knew what he was thinking, comforting him: "Your Majesty, which of the other interstellar civilizations has not developed after tens of thousands of years and hundreds of thousands of years. It has never reached this level of civilization in such a short time like the empire. Moreover, the enthusiasm of the people of the empire has never decreased. In fact, the increase in the population of the empire is definitely very fast. If we develop for tens of thousands of years with peace of mind, the population will definitely reach the number you expect, which will take time!"

Yun Yi nodded helplessly. He understood the truth, but people are always not satisfied with it. They will immediately get more things that are too easy to get. This is just human nature, and Yun Yi is no exception.

It had been long enough for Yun Yi to walk out the door immediately. After the palace and control room were upgraded, some changes were quietly taken, but they were not able to attract his attention. It seemed that the imperial study room where the control room was located had become much bigger, and many high-tech things were quietly hidden in it, waiting for people to discover and use it.

The door opened quietly, and what entered Yun Yi's eyes was a group of people who were already anxious. The five concubines led by Mingyue rushed forward when they saw Yun Yi and asked anxiously: "Yun Yi, is there no problem?"

"What can be wrong? It's just a little longer, don't worry." Yun Yi hugged them apologetically to show fairness. He never leaned towards someone in public. As for what he knew in his heart, only he himself knew.

"Just got a great gift, are you interested in accompanying me to see it?"

Yun Yi nodded to the Prime Minister Li Mu and the others behind them and said to the five people.

"What gift?" At this time, they already knew Yun Yi's origin, including Dai Jiao Dai Pei and Ai Xier, and also understood how their empire developed. Although they could not understand, they at least knew the reason why the empire developed so rapidly.

"In the spaceport, you must also like a top-level luxury spacecraft of the fourth-class that the system father gave me!" Yun Yi couldn't wait to see his own new spacecraft docked in the spaceport.
