The sky is clear and people are happy, and goose feathers and snow are in the light.

The snowfall overnight made the mountain white, and the cold air invaded, Lu Renjia shrunk the quilt tightly, only to hear someone outside: "This damn God, why is it snowing again!" ”

After Lu Renjia packed up his clothes, he rushed out of the door, and the cold wind blew and wrapped his clothes tightly.

The Three Kingdoms period was already in the interglacial period, in 185 years the crops in the north were not harvested, coupled with the epidemic in the north, the Qiang and other ethnic minorities began to revolt, the center of the imperial army began to move north, Huangfu Song and Dong Zhuo went to the north to suppress, as for the fleeing Yellow Turban Army, there was no time to clean.

"Owner, with such a heavy snowfall, I'm afraid our seeds will be in vain." These peasant workers are very distressed about crops. In their eyes, their relatives are not as good as these crops!

Several workers who have planted the fields also do not go to work, and they scold this God, these are their lifeblood!

Lu Renjia said: "Fellow villagers, don't worry, with my Lu Renjia, you will be indispensable to eat, but it's just cold and snow, are we afraid of the mountain?" ”

When everyone saw Lu Renjia behaving like this, the worry in their hearts was also relieved: "Don't be afraid, this bit of snow can't crush us!" ”

As if in response, God tore a hole in the fog and let in the sunlight.

Lu Renjia also thought of several plans in his heart in an instant, but they all vetoed them one by one, "It seems that glass has to come out in advance, and only by building a greenhouse can we save crops!" ”

I can only thank the UP master again, so that I have one more skill to survive in the Three Kingdoms.

Fortunately, the laboratory is not far from the river, and the piles of sand are the same as not asking for money, which also gives Lu Renjia the capital to do experiments, Lu Renjia originally planned to make perfume first, earn back all the money from these words, and then develop others, but this cold wave is obviously higher than Lu Renjia expected.

If the cold wave and the epidemic are not solved, then no matter how strong the army is, it will be a joke, so Lu Renjia cooperated with Zhang Niu and Zhou Laoliu to work overtime again.

"Uncle Zhang, this time I have to rely on you to help me fish out a few denises of sand in the river, and this is the structural diagram of the greenhouse, Uncle Zhou, you bring a few workers to help build the frame!" Lu Renjia wrote the chemical formula on straw paper and calculated it for a while.

Zhou Lao Liu said: "Young General, isn't this place in the ground!" You build a shed, how can these crops still bask in the sun? ”

Zhou Lao Liu is also an expert in planting, so he naturally knows that crops need a lot of sunlight.

But now that the cold wave is cold, what's the use of sunshine, it's completely useless! However, geographically speaking, the earth warms the atmosphere, and the atmosphere returns to the earth, these classic things will not be fake, so it is best to use a glass greenhouse to simulate the scene of the atmosphere returning to the earth, so that the heating can be locked, and the crops will not be invaded by the cold wave!

Zhang Niu also stretched his neck and looked: "Brother Zhou, that's right, young general, you can play anything, if you practice food, you will definitely be scolded by Pei Shuai!" ”

Lu Renjia: "......", what's wrong with me, don't I just want to build a greenhouse? Is this also sinful? Even if I am guilty, please let the court arrest me, instead of sending you two sleeping dragons and phoenixes to torture me!

"It's a cold spell, don't you know? Let crops freeze to death outside? "Lu Renjia doesn't have a good airway.

Zhang Niu took the lead in sending a question: "? What is a cold wave? Cold wave, why don't you let the crops outside, the crops should be taken for granted outside! ”

Lu Renjia: ...... Forget it, I can't talk about you, I gave up, "You work, you say another word, be careful that I deduct your monthly money!" ”

Lu Renjia finally experienced the happiness of a capitalist, and the feeling of deducting other people's wages was really refreshing.

The two sleeping dragons and phoenixes were frightened by the threat of wage deductions, and immediately went to various places.

It didn't take long for Zhang Niu to fish out a lot of fine sand in this cold day!

Lu Renjia shouted: Good guy!

The fine sand that has just been fished out cannot be directly used to make glass, so Lu Renjia repeatedly dried the fine sand for several days, and then used an electromagnet to remove the iron sand before he got the raw materials he wanted.

But then there is a complicated jump, because to make glass, the fine sand and the mixture must be calcined at 1500 degrees Celsius.

It is indeed a very good time to improve the furnace now, because the uprising requires a large number of weapons, and the best weapons are not after the beating, but the weapons made by the pouring method are considered treasures!

The best way to raise the temperature of the furnace to about 1600 degrees Celsius in a short period of time is to add an iron coil to the furnace, so that the fire will gather in the center and not disperse.

So where do the raw materials for iron tools come from? Lu Renjia decisively asked Zhang Niu to contribute his machete.

Zhang Niu was originally wooden, but when he saw that his treasure knife was about to be thrown into the furnace, he was very depressed: "Young General, it's not good for you to be like this, it's not right for you to do this!" ”

Lu Renjia glanced at Zhang Niu, "Give you more monthly money, talk less, do the work, if you don't build an iron coil according to my requirements, then you just wait to deduct your salary!" ”

Zhang Niu, who heard the money, was really silent, is there anything more intimate than money now? And I found a matchmaker in the county to protect the matchmaker, and the most important thing now is to make money!

Under Zhang Niu's "eighty, eighty" sledgehammer, the iron coil has his proper appearance.

Lu Renjia was repeatedly heated, and the iron coil also turned red, and the boiling fire invaded from the bottom, and the dry sand accompanied the additives, undergoing qualitative changes and turning into liquid.

Lu Renjia secretly shouted: It's done, and hurriedly poured the liquid into the mold prepared in advance. What is needed most now is to allow time to precipitate, and after the quenching and annealing process, the glass can be born.

Originally, there was also the appearance of glass in the West at this time, but it was given by nature, and the color was not optimistic, and there were many bubbles, which had no effect except for ornamentation.

Seeing that Lu Renjia was finished, Zhang Niu hurriedly asked: "Young General, you promised me a salary increase, and you won't default on the debt!" ”

Lu Renjia really lost his temper with this money-eyed goods and said, "Have you turned your money-eyed eyes?" How can you open your mouth and close your mouth with money? ”

Zhang Niu was yelled at and said with a smile: "I. . . I asked a matchmaker to be a matchmaker in the county, and I'm going to go to her house in two days! ”

Lu Renjia said: "Who's home?" My Aunt Zhang's house? ”

Two hearty "haha" sounded in the laboratory.

Zhang Niu picked his head in embarrassment: "So, the young general is not that I love money, I can't use it!" ”

Lu Renjia was very considerate: "Don't talk nonsense, you protect the media, I am naturally willing, how long, I will accompany you!" ”
