While Chen Xin was collecting his hair in order to design a drying oven for drying grains, Li Wensheng also sent two sets of fish vegetable symbiosis equipment he wanted to replace the ground source heat pump equipment Chen Xin promised him.

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

When he came to find Chen Xin to pick up the goods, he met Li Yulong, who also came to find Chen Xin. After knowing this, the rich second generation used a piece of Iberian ham and a box of canned tuna to replace Chen Xin's drilling rig and became a designated installer.

Originally Chen Xin did not want to do so, but Li Yulong's persuasion convinced him.

"I think brother Chen, it's too bold for you to do this. If someone plans to use the door-to-door installation method to cheat you out of the shelter, and then murder you or seize your shelter, what will you do?" Although Li Yulong is no less than guessing others with the greatest malice, he still thinks Chen Xin is a little too good.

After listening to Li Yulong's persuasion, Chen Xin agreed to Li Yulong's request to install ground source heat pump.

After all, Chen Xin himself to install, he does not spend survival, it is also a very troublesome thing.

What's more, Chen Xin also thinks that what Li Yulong said is very reasonable. Although he has a gun on his body, he is not likely to have an accident under normal circumstances. However, in case someone swindles him out of his trust and sneaks on him, it will also kill him.

Chen Xin may have been unprepared for coming to him because he was all acquaintances. In addition, Qin LAN and Mo Qingyan are indeed trustworthy, so he subconsciously ignored this problem.

But now that Li Yulong has put it forward, Chen Xin feels that he should still keep this matter in mind and pay more attention to personal safety.

This is an episode, but although it is the ground source heat pump that Li Yulong helped Li Wensheng install, it still brings Chen Xin an income of 400 survival points and an increase of survival point + 4 every day.

As for Li Yulong, he successfully cooperated with Chen Xinda.

It has to be said that there are quite a few businessmen in the city. After Li Yulong instigated his father, in the past few days when Chen Xin stayed in the special police team, Li Yulong's father has got through with the city government and obtained the market operation license.

The municipal government allows Li Yulong to run the industries of market and planting farm, but correspondingly, he still needs to pay taxes as in the past, and the municipal government will send supervisors.

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

And Chen Xin is undoubtedly a very important part of his commercial territory. After all, both markets and farms need Chen Xin's ground source heat pump.

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

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

This is exactly the most important point in this era. After all, whether it is coal or fuel oil, the city needs to rely on external input and railway supply.

If the railway breaks down and the materials cannot arrive in time, it will easily affect the market and farm operation.

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

Because of this, he came to Chen Xin twice in person, and brought the meat, which is very precious now, to do business 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 take a share in ground source heat pump equipment, accounting for 20% of the shares.

In the whole market and farm project, Li Yulong himself accounted for 50% of the shares. Chen Xin took 20% of the shares. Of the remaining 30%, 10% was paid as tax, 10% was attributed to the city government, and 10% was given to the special police force.

Chen Xin doesn't have any opinions on the distribution plan. It's enough for him to take 20% of the shares. As for the separation of the municipal government and tax payment, Chen Xin has to admire Li Yulong's ability to do business.

And the share given to the SWAT team is also due. After all, public security and other things have to be maintained by the SWAT team.

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

Even before the disaster, Iberian ham was very rare. Chen Xin only bought a small bag of cut ham to taste it. The price of the whole ham was at least tens of thousands, which was before the disaster.

In this last age, such a pig leg is a luxury and rare thing. It's hard currency to exchange for anything.

However, Chen Xin did not take this out of the idea of trading, but will be received before Jinhua Ham hanging together, intend to keep their own slowly eat.

These two hams, if eaten carefully, will last him a year or two.

After reaching a deal 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.Knowing Li Yulong's plan, Chen Xin guessed what certificate he and the municipal government would probably offer as the general equivalent of market transaction. However, that kind of thing is far less beneficial to Chen Xin than materials. If Chen Xin wants materials, he has to replace them, so what he wants directly is materials.

As for how to get these materials, that's what Li Yulong needs to worry about. Chen Xin is still designing his own dryer for drying rice.

Chen Xin considered building a layer by layer structure like the circular steamer used by his mother. After drawing the design, he gave up the idea and decided to build a large cabinet with layers of trays inside.

Although the round is good, the structure of the split layer by layer steaming grid is more complex, and the drawer type cabinet is relatively simple.

A large cabinet made of metal materials, which is divided into layer by layer intervals with drawer type trays, is Chen Xin's expected dryer.

As long as the tray is covered with rice, and then the hot air is continuously blown into the cabinet, the harvested grains can be dried to remove moisture.

Chen Xin hesitated about the form of the tray. Although he said he wanted to make it into a drawer, it was undoubtedly a big tray. Is the bottom of the tray made of iron sheet airtight or gauze mesh breathable?

Chen Xin looked at the design drawing he drew and fell into hesitation.
