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

Why is there such a decision, because after systematic detection, currency is still used on the planet, rather than using any energy block as a currency, or in other words, there is no such thing as an energy block on the earth, to say that there is still a battery, but the battery, although it is also one of the energy sources, it can be compared with what energy block.

Therefore, Yang Heng's plan is to see if there are any precious metals that can be refined, or what waste can be spit out by the printer while building the Mars base.

"It's a good place, no one will find it in a month, and besides, this place is a good Martian base if it is properly laid out." Yang Heng pointed to a place on the spaceship and said to Li Er and the others.

"Cheng, listen to you, we don't understand this aspect very well, and the system, it can carry out a series of planning, but it doesn't understand the real needs of people." Unexpectedly, in the past few years, Li Er has really realized the ability of the system, although the system feels very omnipotent, but it is not a human after all, although, it can choose a good place, which is only very good on the drawing, but it is not necessarily applicable to human beings.

And Yang Heng's plan is to build a site that is suitable for human survival and can even allow humans to directly plant crops, so that this base can develop quickly, and even expand it at the fastest speed.

In order to achieve this condition, Yang Heng sent several prospecting airships, but this time they did not let them probe too deep. It only takes about ten meters to become it. Finally. Yang Heng chose a place, this is a place of semi-high ground and half plain, in addition to the upper layer of hematite and gravel, the bottom is the land suitable for growing crops, and even, under five meters, he felt the presence of water, although it was only some moist land, but. This also made Yang Heng see hope, that is, there is definitely water below, no matter what form it is, as long as it passes through some facilities, there will be a self-sufficient water source.

Yang Heng chose a site with a square kilometer in size, and at first, he did not start construction first, but let the printer start hollowing out first, that is. Dig the pit while not printing. And separate all kinds of materials, this action is much faster than direct printing, as long as the machine is fixed in one place to start work, a few days later, a pit of about five meters is dug out.

Yang Heng plans to build a half-ground, half-underground building in this pit, not to hide anything, but to plant something on the roof, to really make use of this space, so that the utilization rate of the building will be higher, and the protective cover can also be lower, and the energy consumption can also be less.

Looking at the printed material, Yang Heng was really stunned, it was stronger than a stone, and even, no binder was used, and it was only sprayed directly, however, the energy consumed was not low, if Yang Heng was to choose, he would rather hire manpower to build such ten places than use a printer to print such a place, but, according to the system, this is strong, can resist a twelve-magnitude earthquake, this, it is really ordinary, even special buildings are incomparable, and, on Mars, Where are you going to hire people, you can't pull a bunch of people from the earth and say buddy, I'll hire you to build a building on Mars, isn't that crazy?

Besides, even after hiring people, it also takes time to build, such a building, a thousand people, can it be built in a year, Yang Heng can't wait.

"Your Majesty, let it be built automatically, leave a prospecting airship here for contact, let's fly to Earth, time is running out, now there is gold, and silver, it should be enough for us to buy ginseng."

It's really enough, in such a place, the printer actually spit out more than ten catties of gold powder, and more than twenty catties of silver powder. This, after being condensed on the spaceship, was condensed into gold and silver bars of 500 grams each.

However, according to the system, the purity of these gold and silver is higher than that of gold and silver on the earth, which may not be detectable on the earth.

"Let's go, the system, parse some of the signals of the earth, see if we can restore it to the image and sound of the format used on the earth, so that we can understand what the situation of this so-called earth is."

"Yes, Marshal, as you wish." "YES, NOU, MY, ......" "WHAT IS THIS, WHY CAN'T I UNDERSTAND IT, AND THESE PEOPLE HAVE BIG NOSES, AND THE COLOR OF THEIR HAIR IS ALSO COLORFUL." Without waiting for Yang Heng to speak, Li Er spoke.

"Back to Your Majesty, this is the most widely used language by human beings on Earth, if Your Majesty thinks it is not appropriate, then analyze and choose." From here again, it can be seen that this system is different from human beings, it doesn't even know that it can find a language that speaks the same language as Yang Heng and these people, and even, when analyzing the signals, it did not translate these signals, but directly chose to use the most one to translate, and this turned out to be English, at this time, Yang Heng suddenly felt a little anxious, maybe the next one is Chinese, and even, Yang Heng still has some expectations, this may be the earth when he crossed the country.

"Ladies and gentlemen, this is Huaxia TV, today is July 25, 2020, Saturday, now broadcast the news, a chaotic foreign country, the domestic situation is very good, according to this reporter interviewed from the space city, Tiangong-8 space city has been officially opened for three months, everything is normal in the opening stage, and it will be open to the society immediately, so that all aspects of scientific research personnel can enter the space city for scientific research, if possible, a small number of people can also be allowed to travel to space, please consult the space city for specific content, Or our advertising department, the phone number is............**Yes............ Little penguins are ............. ”

Seeing this, Yang Hengzheng was a little excited. "What is this, have we Han people on this planet been reduced to a second-rate country, who is the emperor, it is too disappointing for me." Well, Li Er's temper actually came up, do you think they should be the boss with the same language as you.

"System, can you check 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 don't know what Li Er's performance will be.

"What, there was no Tang Dynasty in its history, and Guang was not killed, and then recruited Wagangzhai and had a second youth." This history, which is really shocking, is completely the same as the history of their planet before Yang Guang's assassination, and naturally there are differences, that is, the Li family is still normal when it comes to Li Yuan's father's generation, but then it is not normal, there is no such person as Li Yuan, naturally, Li Er below is gone, however, this Li family has always been a loyal servant of the Great Sui, until the end of the Great Sui, this, Li Er They don't understand, but Yang Heng understands, starting from Guang's son, naturally, Guang's son did not go through Li Er's killing of his brother and brother, but his ability is the same as Li Er, even the queen is the same as the eldest grandson, but the name is different, naturally, there is also an empress, and the empress's name is the same as the history of Yang Heng's previous life, that is, the experience is also the same, including the history of the Great Sui, in addition to the people he brought, the people in the family, except for the Li family, everyone else is actually someone Li Er is familiar with, such as Wei Zheng, Kong Yingda, etc., is this the planet in his last life?

Yang Heng hesitated a little, but in the later history, it is the same as the history in Yang Heng's memory, what five dynasties and ten kingdoms, the Northern and Southern Song Dynasty, all historical celebrities, the only thing missing is the Tang Dynasty.

Yang Heng's depression is Yang Heng's depression, and Li Er and all the ministers and generals are all there to scold the emperors behind them, are they all emperors like losers. (To be continued......)
