After Lu Chen and the fruit farmer confirmed the deal, he pulled a small cart to transport two small heaters to the door of the shelter, and then came to the workshop.

Lu Chen looked at the processed parts that still had half of the space, and the printer that was working on the side, and thought for a while:

"It's a pity that this half of the space is placed, and we have to make another processing equipment, otherwise if there is an emergency, something needs to be manufactured, and the printer happens to be working, then it will not be easy to do."

Immediately, Lu Chen opened the nano core interface, looked for a while, and did not find a suitable equipment, and at the same time, Lu Chen also found that with the increase of his knowledge, there are more and more design drawings, and the difficulty of finding drawings is also increasing.

Lu Chen opened the nano core, operated in the nano core, and divided several categories of sub-items, namely "manufacturing equipment drawings", "collection equipment drawings", "energy equipment drawings", "security equipment drawings", "medical equipment drawings" and other major sub-items, and there are some small sub-items below, and then also used self-learning knowledge to establish a database and simple search program according to the source code of the network search engine in the nano core, so that what kind of equipment you want to manufacture can be directly searched, and if there is one, it can be manufactured directly. If you don't have it, you can redesign it to save time, after all, in this situation, time is not important, sometimes it is important, and it is better to have than nothing.

As Lu Chen finished all this, more than half of the time had passed, Lu Chen got up and moved his body, and before Lu Chen could ask the fruit farmer if he had arrived, there was a horn sound outside the shelter, Lu Chen estimated that the fruit farmer had arrived, and saw a van parked at the door of the house on the ground through the surveillance, and then saw a person coming down, came to the door and pressed the doorbell.

Lu Chen heard the doorbell ringing, and then inquired through the intercom device at the door

"Who?"

"Is it the Rice Worm family? I'm a grower, I'm here to trade."

"I'm a rice worm, hello fruit farmer, please wait a minute, I'll come out right away"

Lu Chen saw that there was only one fruit farmer on the surveillance, and there was no one else in the car, so he took a wrench and put it behind him, and pushed the cart out of the shelter.

Then after the fruit farmer saw Lu Chen, he stopped 5 meters away from Lu Chen.

"Hello, I'm a fruit farmer on the forum, my name is Li Zhi,"

Li Zhi looked at Lu Chen and took the lead in opening his mouth

"Hello, my name is Lu Chen, the rice worm on the forum, the two heaters you want have been prepared."

Lu Chen immediately replied.

"In that case, let's start trading, it's not too early, you wait for me, I'll go and unload the fruit"

After Li Zhi heard Lu Chen's answer, he said to him, and walked to the back of the van to carry down two bags of fruit to Lu Chen, Lu Chen also handed over the two heaters to Li Zhi, and explained to Li Zhi how to use them and how to deal with simple troubleshooting

"Lu Chen, happy cooperation, thank you this time, since the transaction is over, then I'll go back first, it's dark and the road is not easy to walk, I won't bother, I will often contact later"

Li Zhi put the two heaters into the car, said goodbye to Lu Chen, and drove back.

Lu Chen watched Li Zhi's cart walk away, then put two bags of fruit on the cart and entered the shelter

......

Now the temperature outside has begun to drop, itself in May is not very hot, at the highest temperature is only about 30 degrees, after these days the sun can not reach the ground, the temperature and began to drop, now the maximum temperature during the day can only reach 20 degrees, because the sun can not shine during the day, so the surface can not store heat, the night temperature is down to below 5 degrees. In such weather, if you don't keep warm at night, it's easy to catch a cold and get sick, and it will be very troublesome to get sick in the current situation, so when they know that Lu Chen can make a small heater, they will be so eager to trade with Lu Chen, at least in the shelter, they can keep the right temperature to prevent their family from catching a cold and getting sick,

After more than half an hour's drive, Li Zhi returned to his home, connected the two heaters and started them according to Lu Chen's method, and then felt that the temperature of the shelter began to rise, and then Li Zhi set the temperature to 24 degrees, only to see that the temperature began to rise from the bedroom to the entire shelter.

Li Zhi then put another heater into the small plantation. Control the temperature to ensure the normal growth of fruit trees.

In the past two days, Li Zhi and his father have been planning to collect the fruits from the orchard outside, and then cultivate some fruit seedlings to ensure that the plantation inside the shelter can operate normally.

......

After Lu Chen transported the fruit to the shelter, the question of how to preserve it followed, the previous refrigerator was already full of meat, so Lu Chen was ready to build another big refrigerator, but Lu Chen was not ready to make it directly with nanocores, and was going to look for a big refrigerator outside, if it could be used, it would be the best, if it could not be used, find a few more to repair it.

"But this is estimated to have to wait until the transaction to the vehicle, and the fruit is still okay for a few days."

Then Lu Chen came to the workshop, opened the nano core, and prepared to redesign a multi-functional processing platform, which can process some small parts.

Three hours later, after Lu Chen's non-stop operation in the nanocore, a small multi-functional processing platform was designed, which is similar to a machining center and can process a variety of complex parts.

After Lu Chen finalized the design, the nanocore began to generate processing drawings

.......

"Small Multifunctional Manufacturing Platform"

Energy required: 200 points

REQUIRED MATERIALS: 1000KG OF METAL RAW MATERIALS, 20KG OF RUBBER

Manufacturing time: 1H

FLOOR AREA: 2 M LONG, 1.5 M WIDE, 2.3 M HIGH

Description: According to the multi-functional manufacturing platform transformed from the machining center, after retaining some points of the machining center, the processing capacity of complex parts is increased and the manufacturing speed is increased.

Power: 30KW

Processing size: 1000 mm

......

Lu Chen looked at this data and nodded, then looked at the energy of the nano core and had collected 150 points of energy, and it was estimated that there would be five more hours, and then Lu Chen looked at the manufacturing progress of the small heater and found that one had been manufactured, Lu Chen took out one and let it continue to manufacture, and then Lu Chen ate something and began to continue learning.

"It's about nine o'clock in the evening, study until 12 o'clock in the evening, then wash up, add some materials to the printer, and you can go to bed."

Then Lu Chen entered the state of learning, and the entire shelter only had the sound of the machines running in the processing room and the power generation room, and the equipment made by the nano core Lu Chen could rest assured that it would run on its own, after all, it was composed of nano worm nests, which could be repaired by itself, and there was no such thing as natural damage, which could only be destroyed by man or whose service life expired.

At 0:00 on May 24th, the alarm clock rang, Lu Chen got out of the learning state, and then Lu Chen found that the printer had finished its work, took out the heater, re-added the materials, and calculated that two more could be manufactured at eight o'clock tomorrow morning, so that he had four units in stock, and by 12 noon tomorrow, all the required for the transaction would be completed

In addition, when you wake up, you can add a piece of equipment, and the functions of the shelter are becoming more and more diverse, thinking of this, Lu Chen is still very happy, ran to the bathroom to wash up, and then went into the bedroom to sleep
