After everyone's discussion, it was unanimously decided that we could go to Earth to look for ginseng while building a base on Mars.

Why did there be such a decision? After systematic investigation, money is still used on the planet, rather than using energy blocks as a currency. In other words, there is no energy block on the earth. If you want to say that there are still batteries, although batteries are also considered one of the energy blocks, what energy blocks can they compare with?

Therefore, Yang Heng’s plan is to see if any precious metals can be extracted or some waste can be spit out by the printer while building the Mars base.

"This place is good. No one will notice it within a month. Also, if this place is properly laid out, it will be a good Mars base." Yang Heng pointed at a place on the spacecraft and said to Li Er and others.

"Since you, we don't understand this aspect very well. The system can make a series of plans, but it does not understand people's real needs." Unexpectedly, in recent years, Li Er has truly realized the ability of the system. Although the system feels very omnipotent, it is not a human being. Although it can choose a good place, it is just a good thing on the drawings, but it may not be applicable to human beings.

Yang Heng’s plan is to build a territory suitable for human survival and even allow humans to directly plant crops. In this way, the base can develop quickly and even expand at the fastest speed.

In order to achieve this condition, Yang Heng sent several prospecting airships, but this time they did not make them too deep. It was only about ten meters. Finally, Yang Heng selected a place, which was a half-high and half-plain place. In addition to a layer of hematite and gravel above, there was land suitable for planting crops. Even below five meters, the existence of water was felt. Although it was just some wet land, it also gave Yang Heng hope that there was definitely water below. No matter what style it existed, as long as it passed through some facilities, there would be a source of self-sufficient water.

Yang Heng chose a land area of ​​one square kilometer. At first, he did not start construction first, but asked the printer to start hollowing out first. That is to say, while not printing, dig the pit and separate various materials. This action is much faster than printing directly. Just fix the machine in one place to start construction. After a few days, a pit of about five meters will be dug out.

Yang Heng planned to build a semi-ground and semi-underground building in this pit, not to cover up anything, but to plant something on the roof, and to truly utilize this space, so that the utilization rate of the building will be higher, and the protective cover can be lower. The energy consumption can also be less.

Looking at the printed materials, Yang Heng was really shocked. It was stronger than a stone. It didn't even use any adhesive, and it was just sprayed with strong energy. However, the energy consumed was not low. If Yang Heng had chosen, he would rather hire manpower to build such ten places than use a printer to print such a place. However, according to the system, this is sturdy and can withstand magnitude 12 earthquakes. This is really ordinary, even special buildings cannot be compared. Also, on Mars, where do you go to hire people? You can't bring a bunch of people from the earth, saying, buddy, I'll hire you to build a building on Mars. Isn't that crazy?

Besides, even after hiring someone, you need time to build it. Can such a building be completed in one year with a thousand people? Yang Hengke can't wait.

"Your Majesty, let it be built automatically here. Leave a prospecting boat here for contact, let's fly to the earth. Time is not long, and now there is gold and silver, which should be enough for us to buy ginseng."

It's really enough. In such a place, the printer actually spit out more than ten kilograms of gold powder and more than twenty kilograms of silver powder. After being condensed on the spaceship, it was condensed into five hundred grams of gold bars and silver bars.

However, according to the system's explanation, the purity of these gold and silver is actually higher than that of gold and silver on the earth, and this may not be detected on the earth.

"Let's go, the system analyzes some signals from the earth to see if we can restore it to images and sounds in the format used on the earth, so that we can understand what the so-called earth is like."

"Yes, Marshal, as you wish." "YES, NOU, MY..." "What is this? Why can't you understand? Moreover, these people have big noses and the color of their hair is colorful." Before Yang Heng could speak, Li Er spoke.

"By your Majesty, this is the most widely used language for humans on earth. If your Majesty thinks it is not suitable, then analyze and choose it." From this, it once again saw that this system is different from humans. It didn't know that it was found that the same language as Yang Heng and others spoke. When analyzing the signals, it did not translate these signals, but directly chose to use the most to translate it. Moreover, this was actually English. At this time, Yang Heng suddenly became a little anxious. Maybe the next one was Chinese. Even Yang Heng was still a little expectant. Maybe this was the earth he had traveled through time.

"Dear viewers, this is China Television Station. Today is Saturday, July 25, 2020. Now the news is broadcast. There is chaos abroad and the domestic situation is very good. According to our reporter's interview with the Space City, Tiangong-8 Space City has been officially opened for three months. Everything is normal during the opening stage. It will be opened to the society immediately, allowing scientific researchers from all walks of life to enter the Space City for scientific research. If possible, a small number of people can also be allowed to travel in space. For details, please consult the Space City, or our advertising department. The phone number is...** is... Little Penguin is......"

Seeing this, Yang Heng was a little excited. "What's this? Have we Han people on this planet actually become a second-rate country? Who is the emperor, which disappoints me too much." Well, Li Er's temper has actually risen. Do you think they should be the bosses who speak the same language as you.

"System, can you view the history of this Chinese-speaking country?" Now, what Yang Heng really cares about is history. If there is also a Li Er in this history, I wonder what Li Er will behave.

"What, there is no Tang Dynasty in its history, Guang was not killed, and then recruited Wagang Village and came a second youth." This history was really shocking. From the history before Yang Guang was assassinated and the history of their planet, there are naturally different things, that is, the Li family has reached Li Yuan's father's generation, but it was abnormal next time. There was no such person as Li Yuan. Naturally, there was no Li Er below. However, the Li family has always been a loyal minister of the Great Sui Dynasty, until the end of the Great Sui Dynasty, this, Li Er and others.

He didn't understand, but Yang Heng understood. Starting from Guang's son, naturally, Guang's son did not go through Li Er's killing brothers, but his ability was the same as Li Er, and even the queen was the same as Changsun, but his name was different. Naturally, there was also a queen. The name of the queen was the same as Yang Heng's previous life, and the experience was the same. Including the history of the Sui Dynasty, except for the people he brought, the people in the family, except for the Li family, were all familiar to Li Er, such as Wei Zheng, Kong Yingda, etc. Is this the planet he had in his previous life?

Yang Heng hesitated a little, but the subsequent history is the same as the history in Yang Heng's memory. The only thing that all historical celebrities lack is the Tang Dynasty.
