After eating breakfast, Chen Xin and Qin Lan, who were allowed to leave, naturally did not stay in the hospital for long.

After receiving the seeds from Hongrui, the two left the shelter where the hospital was located.

Thanks to the fact that the tunnels between the major evacuation centers are now gradually connected, it is no longer necessary to travel in the low temperature of minus 20 or 30 degrees above the ground to return to the city office, but to pass through the underground tunnels with a warmer temperature.

And doing so is just a detour to another shelter.

With the identity of Qin Lan's SWAT team, Chen Xin and Qin Lan hitchhiked a ride, and drove towards the refuge of the Polytechnic University.

"Master, what are you sending here?" Sitting in the car, Chen Xin felt a little dull, so he chatted with the driver.

"Some commonly used medicines and medical consumables, some medical supplies are running out of medical supplies at the health center over there, and my car is going to replenish the stock." The driver replied to Chen Xin with a smile and explained his purpose.

Chen Xinyi chatted with the driver without a ride, and when he saw the smile on his face, he couldn't help asking: "Master, I think you're very happy!" Now in this world, there are not many people who can be as happy as you! ”

"Hey, what is this acid! When I used to run long distances outside, I didn't encounter a worse situation than this. Besides, it's not that life can't go on now, and it's not that there have been hard times before, as long as you don't die of hunger, what are you worried about? Besides, it's a day for you to cry and mourn, and it's a day to laugh, so why don't you laugh? The driver looked indifferent and smiled at Chen Xin again.

Listening to the driver's words, Chen Xin also laughed: "Master, you are very open-minded!" ”

"What's open-minded or not, it's just a little more open-minded than others, as long as life can go on, there's nothing to be unhappy about." The smile on the driver's face seemed to be infectious, and even Qin Lan, who had been sitting on the side, couldn't help laughing.

Because it was an underground tunnel and there were no forks or curves, the car quickly arrived at Polytechnic University.

After getting off the bus in the underground parking lot of the Polytechnic University and saying thank you to the driver, Chen Xin and Qin Lan looked around, planning to take another bus to the city hall and return to the city bureau from there.

However, because there are not many cars going to the city hall from the Polytechnic University, the two of them can only wait for a car to come out at the entrance of the underground tunnel of the station.

Looking at the deep underground tunnel in front of him, Chen Xin couldn't help but sigh: "Our country's infrastructure capacity is really strong, such a tunnel can be dug in a few months!" ”

"It's normal, isn't it? This tunnel is not long, and now there is surplus manpower, so it is normal to dig and repair at the same time, and the speed is fast! Qin Lan didn't feel anything about this, but felt that Chen Xin was a little fussed: "And now there is nothing like arrears of project payments, wages can be paid monthly, or even daily, and workers are pointing to work and eat, work harder, and repair faster, right?" ”

Regarding this question, Chen Xin could only raise his eyebrows and said: "I can only say that Ah Lan, you are used to the speed of infrastructure construction in Yanguo, and other countries are not so fast." ”

Speaking of this topic, Chen Xin couldn't help but think of the time when he could still surf the Internet in the past, he could often see foreigners on the Internet lamenting why Yan Guojian was fast at everything, and complaining that his country was slow to build everything.

When he first saw it, he couldn't understand why some countries could build a road for more than ten years, and an airport had to be built from 1959, until 2000, when it was officially named, and construction began in 2002.

It wasn't until he understood more and more things that Chen Xin understood that it was not that other countries were slow, but that Yanguo was too fast.

However, there is no point in discussing this topic now, because there are still two theories about whether foreign countries exist or not, and who can compare the speed of infrastructure construction with Yanguo?

Perhaps Lucia still exists, and the continental powers of Britain, Gaul, and Hans may or may not survive, because their governments are so speechless about their ability to control the country.

As for the Federation of Blue Star's first powerhouse, which should have a great chance of surviving, it can only be said that God does not bless the Federation, and all beings under the meteorite are equal.

If you're a little unlucky, and a meteorite hits Yellowstone National Park and causes the Yellowstone volcano to erupt, or hits an earthquake zone or something, then you can only wish the people of the Federation good luck.

Thinking about these things, Chen Xin and Qin Lan finally waited for a car that happened to carry the police on duty back to the city bureau, and they returned to the city bureau smoothly.

When he returned to the city bureau, Qin Lan was explained by the political commissar to accompany Chen Xin in the past few days, so he did not go to duty, but followed him.

Chen Xin had nothing else to do in the city bureau's shelter, and even though he had just returned from the hospital, he still went to care about the installation of the ground source heat pump.

Although Chen Xin was not present, when discussing with the engineer yesterday, Chen Xin had already communicated the relevant technical parameters and installation issues with the other party in detail, so even without Chen Xin's presence, work such as drilling and drilling was still going smoothly.

Wearing a mask and watching a few workers drilling holes in the floor, Chen Xin pulled the engineer in charge of the on-site construction to the side and asked him loudly, "Is there any problem with the installation?" ”

"No, at present, it is being punched according to the size you gave by Chen Gong, and the steel plate will be paved for the ground in a while, and the equipment will be put on after leveling and aligning." The engineer explained to Chen Xin, and at the same time opened the drawing in his hand and explained to Chen Xin: "At that time, you will need Chen Gong to be responsible for debugging the equipment." ”

"It's a matter of duty." Chen Xin had no objection to this, since he didn't need to drill holes by himself, he was also happy to relax, standing aside and watching these workers busy.

Although Qin Lan couldn't understand what these workers were doing, her current task was to accompany Chen Xin, so she didn't have any opinions, so she just stood beside Chen Xin and accompanied him to watch the workers construct.

Soon the workers had drilled holes in the ground, driven the expansion pipes, and began to install steel plates on the ground as footings.

Watching the construction of the workers, Chen Xin couldn't help but have an idea in his heart, that is, if he now uses the system functions and spends survival points to install the six ground source heat pumps, in the eyes of these workers, what is the installation process like they understand?

However, this idea was dispelled by Chen Xin after a while in his mind, although there are a lot of survival points now, and he was prepared like this at the beginning, but since there are workers in the construction, it is better for him to save a little, there is no need to waste survival points so much.
