Chapter 269 Refrigeration Coal

Return to Poseidon.

After careful consideration, Zhou Yi decided to tell Tietie the truth.

"I am not a celestial being."

"My name is Zhou Yi. Like you, I am a human being, but I have had similar experiences to you."

Tietie was very happy: "That's great. If it was a god, I wouldn't dare to say a lot and would be very nervous. If you are the same kind, at least we can talk more. Right?"

Whether she was being used as a sacrifice, doing hard labor in outer space, or losing her perception and falling, she always maintained a positive and optimistic attitude.

This also infected Zhou Yi.

Compared with Tietie's unfortunate fate, the troubles he encountered didn't seem to be a big deal.

His mood also became more relaxed.

"Zhou Yi, is the world on earth still the same as before? Are there still mountains and water, mice, and fruits?"

“The natural environment is not much different.”

"I'll tell you a secret. Cover your ears and you can hear the sound of running water."

"That's the sound of blood flowing in the body."

"The sound of blood? That's what's going on. I thought I was the only one who knew that!"

……

"Zhou Yi, do you know Shanhou Village? It's my hometown."

"Have not heard."

"That's what we call it anyway. Before I was taken away by the servant of God, I had been living in the mountains over there. If you meet me on the way, can you help me go back and take a look?"

"it is good."

Zhou Yi hesitated for a moment, but finally told the other person the truth: "It's been many years since your time, and the village must have changed a lot."

"I know. We have a saying over there that one day in heaven is one year on earth. Although I don't know how much time has passed, they are definitely not the people I know anymore."

"I just want to tell them. If you are chosen as a sacrifice, you must not talk casually when you go to heaven, and don't talk to others, so that you can live longer."

Tietie said so.

Zhou Yi was silent for a while.

"Okay, I'll help you keep an eye on the village."

"Thank you."

"It's okay. I need your help, too."

"You're welcome, if you ask."

……

End of this conversation.

Zhou Yi was just about to close his eyes and rest when Xiaofu's voice rang in his mind again.

"Da Zhou, Tietie's ability potential is very high."

"Remember? I said that higher-dimensional civilizations will secretly transfer part of their cultural heritage, whether spiritual heritage, material heritage or preserved life information, to other worlds through circular flow."

"Even if there are relevant clues, it is extremely dangerous to touch those cultural heritages. Because they will be guarded and protected in various forms."

"But if we can call upon Tietie's ability, we can prevent the protective consciousness from knowing of our presence, and won't trigger alarms or attacks, so we can sneak into those hidden storage points!"

The upstreamer actively suggested: "We must make good use of this ability."

Zhou Yi said: "Just decompress the iron and restore it when needed."

"That process is too complicated and time-consuming. Many operations need to be completed in an instant."

The Stream Tracer said: "To directly call upon the abilities of the Spark life forms, one needs to build a Spark civilization, which requires at least 150 Spark life forms to be connected. However, there is also a transitional method, which is to build a [Fire Chamber Disc]. This circular flow device can hold three Spark life forms, and one can call upon their abilities directly for one's own use by means of a turntable."

"For example, you can directly use Maiba's "BGM Field" or Tietie's "Ecstasy". Both the strength and accuracy are the same as those of the ability holder. "

There is such a thing.

Zhou Yi immediately perked up.

He was a little unhappy again: "Why didn't you say it before?"

"The fire chamber disc is more complicated and sophisticated than the fire transmitter. It takes a year to make."

Suneo said, "Once I start making the circular flow device, I will no longer be able to distract myself from talking to you. I must immerse myself in the manufacturing process. If I am interrupted, I will have to start all over again."

"There was no need to build it before, but because the ability mechanism of "selflessness" fits the treasure hunt, and I have previously recorded two places where heritage is suspected to be hidden, so I mentioned this matter because it is necessary."

Zhou Yixin said, what a great guy.

It turns out that it was planned long ago.

"Start building it. For one year, I will not interrupt you under any circumstances."

"Then there is no time to lose. I will start working now."

……

The Poseidon docked at the pier in Yalong Bay.

Zhou Yi stopped by to visit the two mutants in the cave nearby.

He found that Li Mo and Tiangou were still making cups with their original intention.

"Chairman."

"This is a new cup we made. It cools you down."

"Isn't it hot in summer? With this cooling cup, it will be cool."

Li Mo raised the black cup in his hand.

A cool icy mist poured out from inside.

Zhou Yi took it and looked at it. The handle was very cold, as if there was a small refrigerator inside that was cooling the air around the mouth of the cup.

"What's the principle?"

Li Mo chuckled: "Just put some bitter root powder in it, light it and it will cool down, which complements the Flame Cup."

Zhou Yi was so happy that he thought it was a new technology product, but it turned out to be a patent of Dali.

"Chairman, besides asking Dali for advice, this cup also contains something of mine and Tengu's own."

Seeing that his face was not right, Li Mo quickly explained: "We thought that if the bitter root could be made more resistant to burning, it would be able to provide long-term refrigeration. So after repeated tests, we added coal, clay extracted from the Dead Sea mud and other substances. The effect was unexpectedly good. Mixing bitter root, coal, wood residue, quicklime and clay in a ratio of 1:1:1:1:6 is refrigeration coal."

"Although this cooling speed is not fast, it is just right for cooling a small area and can reduce the indoor temperature to as low as 20 degrees Celsius."

"And most importantly, the consumption of bitter roots is very small. One piece of refrigeration coal can burn for 12 hours. In the past, the same amount of bitter roots could only burn for 3 minutes. We have increased the endurance by 240 times!"

The older child said with some pride: "Although it is not an advanced technology, it can greatly reduce our bitter root expenses. Dali said before that he would cultivate bitter roots for a few more years. Now it is completely enough! We can use bitter roots for refrigeration continuously."

Zhou Yi frowned: "Why didn't you report this?"

“Because we also want to strive for a better ratio, reduce costs as much as possible, and also add some natural flame retardants.”

Li Mo smiled. "However, Tengu and I also consulted many people in this regard. Cao Dayuan and Yuan Tong helped a lot. They selected the right clay and found the flame retardant."

"We are also thinking of placing cooling cups in underground caves, lighting high-concentration cooling coal, and injecting water, so that we can have ice cubes to use in the summer."

"This has been proven to be feasible. We just need to increase the proportion. The underground can maintain a low temperature for a long time, and the energy consumption is much lower than that on the ground."

"Later, we asked 703 to help us simulate our refrigeration coal through the program to quickly find the precise ratio and the most suitable container structure. The underground ice storage and indoor cooling environment are different, so there are many differences."

This made Zhou Yi think of it.

If refrigeration coal technology is really feasible and mass-produced, ordinary houses can also stay cool in the summer.

More importantly, once an ice storage is built, many foods can be stored for a long time without worrying about spoilage.

And iced cola! iced coffee!

Zhou Yi felt excited.

"The specific drawings and samples are at 703, you can go and have a look. We are testing some new structures here, and they are actually the ones who will make the final improvements on this application." Li Mo looked to the side and said, "Tengu, you can say something too."

The dog-headed man was silent for a while, and then said, "Li Mo is right."

"…You guys continue."

Zhou Yi hurried back to Emerald City and came to the programmers' container office.

No 703 was seen inside, only Programmer Walker was there.

"What about the rest?"

Walker said, "Chairman, 703 went to the cattle-taming tribe and is repairing the semi-civilized body there. Number went to test and collect driving data of the horned cattle. Mr. Yuan Tong invited the little elephant to the dam. They designed the latest large-scale desperate machine and are testing it."

Programmers are already shining in various fields.

Zhou Yi felt very relieved.

"Walker, Li Mo and Tengu said that the latest drawings and samples of the refrigeration cup technology are with you?"

"Yes, Chairman."

The wheels under the humanoid robot turned and it came to the southeast corner.

There are a bunch of strange wooden models and some metal devices of various shapes. It moved out a square wooden box about 1 meter long and wide and placed it steadily on the workbench next to it.

A faint white smoke was still coming out of the wooden box.

Walker opened the lid of the box and a gust of cold air wafted out towards him.

"This is a refrigeration box that we modified based on the refrigeration cup."

"Compared to cup-type appliances, box-type appliances have larger space and capacity. Fixing the refrigeration range can reduce consumption, and you can also see the consumption of refrigeration fuel more intuitively."

The refrigerator box adopts a two-layer wooden board structure, with a large amount of soil filled between the wooden layers.

This style is quite primitive and rough.

Zhou Yi was a little uncertain: "Is the inside ordinary soil?"

"Yes."

Walker said: "Chairman, we tested a lot of common materials. We ruled out extremely expensive composite materials and finally found that soil, plant fiber and wool have the best insulation effect."

"Among them, soil is the easiest to obtain and adjust, and it is also the cheapest."

"There are gaps between soil particles, and these gaps are filled with air, and air is a poor conductor of heat, so soil can effectively slow down the conduction of heat."

"On the other hand, soil contains water, which has a higher heat capacity and can absorb and store more heat, making the temperature change slower."

"We use mud as the internal insulation layer. Although it looks simple, it is effective. If the effect becomes weak after being used for too long, it can be easily replaced and removed."

Zhou Yi gradually accepted this slightly rustic and strange device.

As long as it works.

The space inside the refrigeration box is divided into two layers, upper and lower.

The large upper space is used to store materials that need to be frozen. Currently, a frozen chicken skeleton is placed in it. Apparently, the effect is good.

On the lower level is a tray rack with four small honeycomb coals on it, which are lighter in color than normal coal.

"This is the cooling coal we have finalised the size for, which can be ignited with a combustible material such as hay."

Walker said: "Mix the bitter root powder with other materials in proportion, press it into shape through a mold, and dry it in the sun or in the oven until it reaches the appropriate hardness before use."

"However, after it is ignited, some smoke will be produced inside and will float out through the soil and wooden boards. It is best to keep the room ventilated or equip it with a special smoke exhaust pipe to avoid safety hazards. This needs to be optimized later."

It raised its mechanical arm and pointed at the four pieces of honeycomb briquettes.

"There are currently two specifications of refrigeration coal. No. 1 coal is used for refrigeration, which can ensure that the temperature inside the box remains at around 5 degrees, which is sufficient for normal food preservation. No. 2 coal can be used for freezing, keeping the temperature below -18 degrees, but the cost is also a bit higher."

Zhou Yi asked it: "How much does this set cost?"

"The refrigeration box is made of simple materials and is cheap to make. It costs about 200 mushrooms, which is not much more expensive than an ordinary wooden box."

"The most expensive part is the cooling coal. The nearest coal producing city is Steel Refining City. The price of coal briquettes there is 10 mushrooms per 1 block. We buy them and process them into No. 1 coal. Because there is an abundance of bitter roots in nature and we are still planting them on a large scale, the average cost of raw materials is 15 mushrooms per 1 block."

"Every day, the refrigeration box is kept running, and two pieces of refrigeration coal are consumed. This means that the daily cost is at least 2 mushrooms, and 30 mushrooms a month."

Walker said: "According to your requirements for the company's products, we need to ensure that more people can afford it. This is already the lowest cost under the current plan and there is no way to reduce it any further."

It is summer now.

The refrigeration box should be dealt with sooner rather than later.

Zhou Yi immediately called Gong Zheng, Zheng Tao and Qian Su to discuss the matter.
