Zhao Yu walked into the control room and spent 1,000 technology points to redeem the Hall thruster production line.
After the upgrade, all newly built nuclear-powered spacecraft can be directly installed with Hall thrusters.
But the spaceship that has already been built needs to be remodeled.
After leaving the control room, Zhao Yu told Uncle Da about the transformation.
"Okay, sir, I will arrange for the spacecraft from various bases to come back in turn to replace the thrusters..."
Zhao Yu nodded and then asked: "How many spaceships do we have now?"
"About 100,000 ships, most of which are transport ships..."
"So how is the progress of the first line of defense?"
"It is 18% complete. According to Xiaotian's current mining efficiency, it will be completed in about 15 days..."
"I allocated part of the 2 billion Blue Moon Coin resources you brought back last time to expand the production lines of various types of spacecraft..."
Zhao Yu nodded and said: "Now that the spaceship has been upgraded, can you make a plan to send the spaceship to other planets?"
"Yes!"
Uncle Da took out the plan, handed it to Zhao Yu, and said: "There are four planets closest to us, Mercury, Venus, Blue Star and Mars..."
"Blue Star is the closest to us and produces about 300 million Blue Moon coins equivalent resources every day..."
"The rest, based on the current round trip time, is 10 days for Mercury, 15 days for Venus, and 20 days for Mars..."
"Sending Xiaotian back and forth is too troublesome. My idea is to directly establish a resource collection base on these three planets, set up Xiaotian production lines, unlimited manufacturing of Xiaotian, unlimited mining of mineral resources, and then each time a part of the resources are collected,
Send a transport ship to transport it back..."
There are no people on these three planets, so when mining, you don’t need to worry as much as on the Blue Star, and you can start mining freely.
Zhao Yu nodded slightly, "Where's Jupiter, how long does it take to get there?"
"Jupiter is still too far away. Even if Hall thrusters are installed now, it will still take 4 months to make a round trip..."
"The alien fleet will arrive in a month. I'm afraid that even if we send a spaceship there, we might be shot down before we get there..."
"Forget it, these four planets are enough in the early stage. Besides, we also have a lot of resources on the moon..."
The two briefly discussed the alien fleet.
But now, there is too little information, and all available weapons and defense facilities have been arranged, so it is useless to think too much.
Zhao Yu thought of Mr. Yang, whom he met when he was leaving, and asked, "What happened to Zhang Tao and the others?"
"Sir, I have gained some insights from observing Zhang Tao, but the other 88 people have made no progress..."
Uncle Da was a little confused, "They don't seem to have much emotional fluctuations. They just eat, drink and have fun every day. They don't fight or have sex..."
After a pause, he added: "Sir, I wonder if their environment is too closed, so they don't have this emotion..."
"So, I think, let's just release them and work like Zhang Tao?"
Zhao Yu nodded slightly and said: "In addition to employee levels, you can also set up a welfare system. According to Blue Star's standards, each level will enjoy what they have. In addition, they will be given a salary every month..."<
/p>
"Sir, what's the salary?"
"Just give out Blue Moon Coins..." Anyway, I printed this thing myself, so you can have as many as you want.
After Zhao Yu considered it for a moment, he added: "If we build a living area that can accommodate 100,000 people, how many resources will be consumed?"
"A few hundred Blue Moon coins should be enough..."
"In this case, then you build a living area that can accommodate 100,000 people..."
"Sir, do you plan to establish a country?"
"No!"
Zhao Yu shook his head and said: "The alien fleet will arrive in a month. I am worried that Blue Star will be destroyed or cut off from contact, so make some preparations in advance..."
The fastest way for him to obtain technology points now is to trade with Blue Star people.
If you can also get technology points by trading with the Blue Star people living on the moon, then you don't need to be so troublesome.
[Tip: The number of civilized people trading with the mysterious merchant must not be less than one million.]
As soon as he finished speaking, Zhao Yu got a prompt from the system, which made him a little happy. This showed that in the system's view, Blue Star people could immigrate to the moon, and they could trade with them as long as the population was greater than one million.
"Uncle Da, the living area has been expanded to accommodate five million people, and all facilities have been built in accordance with Blue Star standards..."
"Five million?" Uncle Da was startled. With a population of five million, it can cost less than 10,000 Blue Moon coins, which is quite simple.
For Blue Star, the biggest cost of building a city that can accommodate five million people may be the labor cost.
But for them, the biggest cost is resources, and manpower has been replaced by robots.
There are now countless robots in the base, many of which have nothing to do and are just used to expand the living area.
"How long will it take to complete the living area?"
"Five days should be enough!"
Zhao Yu nodded slightly. The next difficult part is how to ask Blue Star for someone.
Thinking of this, he tried: "If we merge with Blue Star, can we still trigger the mysterious businessman?"
[Tip: The mysterious merchant can only be triggered when trading with other civilizations.]
Zhao Yu just gave it a try, but he didn't expect to actually get the system prompts in this way.
"So, even if we want people from Blue Star to come over, we can't merge them in. We can only let them immigrate as Blue Star people..."
"Sir, there are so many immigrants here, what kind of jobs should we arrange for them?"
Uncle Da was a little confused and explained: "Almost all the jobs in our base can be done by robots. Zhang Tao's job was forced to be found for him..."
Millions of people suddenly came here, and if we didn’t find something to do for them, they wouldn’t be able to release their energy.
Zhao Yu thought about it carefully. What machines cannot replace at present is creative work.
"When you say that, I know who should immigrate here..."
"You can also turn your living area into an entertainment city!"
Zhao Yu thought about it. He faced a bunch of machines every day. If there was an extra place to eat, drink and have fun on the moon, he could go there and relax when he was irritable.
"Sir, with such a large-scale immigration, we may not be able to hide our identity as aliens..."
"If I can't hide it, I won't hide it. It was originally a requirement of the Blue Star Federation. I'm afraid of social unrest..."
Zhao Yu shook his head and planned to rest for a few days. When everything here is settled, he would go to Blue Star again to talk about immigration.
