When Chen Xin was cutting his hair in order to design a drying box that could dry grains, Li Wensheng also sent the two sets of aquaponics equipment he asked for, and exchanged the ground source heat pump equipment that Chen Xin promised him.

Originally, Chen Xin said that he could install it on his door, but Li Wensheng did not enjoy Chen Xin's door-to-door installation service.

Because when he came to Chen Xin to pick up the goods, he met Li Yulong, who also came to Chen Xin, and after knowing about it, the rich second generation replaced the drilling rig on Chen Xin's hand with an Iberian ham and a box of canned tuna, and became the designated installer.

Originally, Chen Xin didn't want to do this, but Li Yulong's persuasion persuaded him.

"I think Brother Xiao Chen, you are too bold to do this, not to mention anything else, what if someone plans to trick you into leaving the shelter by means of door-to-door installation, and then kill you for money or seize your shelter?" Although Li Yulong is tantamount to speculating on others with the greatest malice, he still thinks that Chen Xin is too good.

After listening to Li Yulong's persuasion, Chen Xin agreed to Li Yulong's request to install a ground source heat pump after thinking about it.

After all, Chen Xin pretended to be by himself, and if he didn't spend survival points, it would be a very troublesome thing.

And more importantly, Chen Xin also felt that what Li Yulong said was very reasonable, although he had a gun on him, he would not have an accident under normal circumstances, but if someone deceived his trust and attacked him secretly, it would be able to kill him.

Chen Xin may have been defenseless because they were all acquaintances who came to him, and Qin Lan, Mo Qingyan and others were indeed trustworthy, so he subconsciously ignored this problem.

But now that Li Yulong has brought it up, Chen Xin feels that he should still take this matter to heart, and he should pay more attention to personal safety.

This incident can be regarded as an episode, but although it was the ground source heat pump installed by Li Yulong for Li Wensheng, it still brought Chen Xin an income of 400 survival points and an increase of +4 survival points per day.

As for Li Yulong, he successfully reached a cooperation with Chen Xin.

I have to say that he is worthy of being a businessman in the city, after Li Yulong said that he moved his father, in the few days that Chen Xin stayed in the special police team, Li Yulong's father has opened up the relationship with the city government and obtained the market operation license.

The city government allowed Li Yulong to operate markets and farms, but correspondingly, he still had to pay taxes as in the past, and the city government would send supervisors.

But now that the license has been obtained, it is enough for Li Yulong, which means that he can start his own business territory plan.

Chen Xin is undoubtedly a very important part of his business map, after all, whether it is a market or a farm, Chen Xin ground source heat pump is needed.

Although for Li Yulong, it is not difficult to get other heating equipment after opening up the relationship between the city government, but as a rich second generation, he chooses the best for everything.

After a horizontal comparison, Li Yulong was also convinced that Chen Xin's ground source heat pump was the most efficient heating equipment and could be self-sustaining.

This is precisely the most important thing in this era, after all, whether it is coal or fuel oil, the city needs to rely on external inputs, relying on railway supply.

If the railroad breaks down and supplies don't arrive in time, it can easily affect the operations of markets and farms.

Therefore, ground source heat pumps, which can be better self-sustaining, have become Li Yulong's first choice.

It is precisely because of this that he came to Chen Xin twice in person, and brought meat, which is already very precious now, to trade with Chen Xin, in order to get the opportunity to cooperate with Chen Xin.

After comprehensive consideration, Chen Xin did not refuse Li Yulong, and agreed to invest in ground source heat pump equipment, accounting for 20% of the shares.

Li Yulong himself took 50 percent of the shares of the entire market and farm project, Chen Xin took 20 percent, and of the remaining 30 percent, 10 percent was paid as taxes, 10 percent went to the city government, and 10 percent was given to the special police team.

Chen Xin has no opinion on this distribution plan, it is enough for him to take 20% of the shares, as for the separation of the city government and tax payment, this makes Chen Xin have to admire Li Yulong for doing business.

And the one given to the SWAT team is also what it should be, after all, the current law and order have to be maintained by the SWAT team.

So after reaching a transaction intention, Chen Xin also accepted the materials sent by Li Yulong very unceremoniously.

Iberian ham was a very rare thing even before the disaster, Chen Xin had only bought a small packet of cut to taste it, and the price of this whole ham was at least tens of thousands, and this was before the disaster.

In this apocalypse, such a pork leg is already a complete luxury and rarity, and whatever you want to exchange for is hard currency.

However, Chen Xin didn't have the idea of going out to trade, but hung it with the Jinhua ham he received before, and planned to keep it for himself to eat slowly.

If these two hams are eaten carefully, they will be enough for him to eat for a year or two.

After reaching a transaction intention with Li Yulong, Chen Xin also gave him a list of materials he needed, and explained to him that his share dividends were converted into these materials.

Because he knew Li Yulong's plan, Chen Xin guessed that he and the city government were likely to launch what vouchers as the general equivalent of market transactions, but that kind of thing was far less affordable for Chen Xin than materials, and if Chen Xin wanted materials, he would have to exchange them, so what he directly wanted was materials.

As for how to get these materials, that is what Li Yulong needs to worry about, Chen Xin is still bored in designing the dryer he uses to dry rice.

Chen Xin considered making a layer-by-layer structure like a round steamer like the household dryer his mother used, but after drawing the design, he dismissed the idea and decided to make a large cabinet with layers of trays inside.

Although the round shape is good, the structure of the split layer by layer steaming grid is more complicated, and it is relatively simple to make a large cabinet in the drawer type.

A large cabinet made of metal materials, which is divided into layers and layers of partitions with drawer-type trays, is the dryer that Chen Xin envisioned.

By simply spreading the rice on the tray and continuously blowing hot air into the cabinet, the harvested grains can be dried and the moisture removed.

It's just that Chen Xin is still a little hesitant about the form of the tray, although it is said to be a drawer, but it is undoubtedly a large tray, and the bottom of the tray is made of iron sheet to make it impermeable, or is it made of gauze to make it breathable?

Chen Xin looked at the design he had drawn and fell into hesitation.
