In the evening, everyone sat in the house and chatted and talked.

The weather outside is no longer suitable for work, the temperature has plummeted, and the north wind is howling.

Don't say it's burning, even if you go out to the toilet, you will be frozen.

In today's extreme weather, it doesn't take a minute to freeze a person who takes off his clothes.

In the place of the door, a wooden barrel is placed, and this is the way to solve the problem.

When needed, take the items from the doorway into the curtain and put them in the card slot outside the door when you are done to prevent the barrel from shaking over.

Before going to bed, everyone will try not to drink water, and sleep until dawn, and will not wake up in the middle of the night.

It was about five or six o'clock in the evening, and it was already dark outside, and everyone gathered around the fire, chatting and eating.

Zhang Xiangyang ate a kiwi fruit handed over by Zhang Hailing, and this one in his hand was not very familiar, and it was the most delicious moment.

Everyone will give priority to taking some kiwifruit that is almost ripe out of the fruit room and eating it, and these kiwifruits will spoil quickly after they are ripe.

Zhang Bin ate the kiwifruit, and after taking a bite, he raised the kiwifruit in his hand and said casually: "After we make copper sheets, we can use this to generate electricity." ”

Lingling looked at Zhang Bin and said angrily: "You can make a light bulb?" ”

"......No," Zhang Bin replied with a smile, and then continued to eat.

There are many things that can generate electricity, and how to save and use the current is the problem.

There is a lack of materials and processes, both for machines and appliances.

At present, these people are more hands-on, and they have not yet reached the level of making TVs with their bare hands.

A lot of things are not people in the professional field and simply don't understand the specific steps.

Even if you are a worker in an ironworks, you are exposed to the knowledge of your position.

The most valuable of this science and technology team is the dead chief engineer, who knows more comprehensively than the rest, and is more suitable to lead the team to develop a system faster.

Zhang Han said: "Don't think about whether to generate electricity or not, let's practice iron first." ”

Wu Sang said: "It should be soon, the iron ore brought back by Xiangyang has a high iron content, and the iron can be directly trained, and the main problem is how to increase the temperature of the flame." ”

Lingling handed Zhang Xiangyang another piece of jerky, and said with a smile: "Give, reward you~"

Zhang Xiangyang took the jerky, smiled and continued to eat with his head down.

This is a wolf jerky that has been preserved before, and it can warm up the body a little after eating.

Wan Jing said: "The melting point of iron is 1535 degrees, bronze's is 870, the general temperature of charcoal fire is 800, and the wind power and sealing can reach more than 1,000. ”

The recent severe cold weather has made Wan Jing, who is in charge of material statistics, feel tricky.

At present, charcoal is burned in the house, and charcoal is used for iron smelting outside, and the storage capacity has been used to the extent that nearly one-fifth of it has been used!

Iron smelting is not necessary, how to survive this winter is the most important thing at the moment!

Wu Sang also understood this, and said at this time: "Now a lot of iron has been refined, as long as it is finally heated and hammered together, it can be made into iron tools, and if you insist on it for another two or three days, you can have iron weapons if you practice this batch of iron ore well!" ”

Wan Jing frowned and said, "I think the iron tools we can make now are not much different from bronze tools, and our technology and craftsmanship can't make iron tools the same as modern iron tools!" ”

Wu Sang really wanted to make iron, and this matter was delayed back and forth many times.

She had already decided to give up, but Zhang Xiangyang mentioned this matter again, which made Wu Sang desperately want to do this thing quickly, and she didn't want to do it in the future.

Wu Sang looked at Zhang Xiangyang, who was eating, and Zhang Xiangyang was as low-key and silent as ever.

"Xiangyang, what weapon do you want? I want to give you the right to define the first piece of iron! ”

Everyone looked at Zhang Xiangyang, and Zhang Xiangyang raised at this time
