Chapter 742

The people immediately sighed with disappointment. The millennium is too long for them to see.

Merton said confidently, "although it is impossible to achieve it at present, if the Mohists have been studying it, it will certainly shorten the process several times."

"That's hundreds of years later," Li Shimin sneered, and didn't want Merton to muddle through so easily.

Merton gritted his teeth and said, "if your majesty wants to see the results immediately, there is one for Weichen."

"Oh!" the crowd couldn't help looking at Merton.

"Pressure cooker!" Merton said word by word.

"What is a pressure cooker!" the crowd looked at Merton in disbelief.

Merton said proudly, "I'll cook on weekdays. As long as the water in the pot boils, it won't be long before it will be cooked. The Mohists count the freezing of water as zero and the boiling of water as 100 degrees."

As soon as Li Tai's eyes lit up, he quickly took it to heart.

Merton then said, "however, during the western expedition, Wei Chen heard a strange story. When the southern route army led by general Hou and General Li was marching on the Tibetan Plateau, he wanted to camp and cook, but he found that the water was boiling, but he couldn't cook the pasta and meat at all. He tested the water temperature by hand. It was far less hot than the boiled water in the plain."

"Should there be such a miracle?" Li Shimin said strangely.

Merton solemnly said, "this is the personal experience of tens of thousands of soldiers. How can Weichen talk nonsense? Since it was found that they were not cooked well, many soldiers mostly ate dry food or barbecue directly, which did not affect the March."

Li Shimin just nodded. So many people have experienced it personally. If they want to come to Merton, they will not lie here.

"Does it have anything to do with the atmospheric pressure?" Li Tai asked puzzled. Of all the people, I'm afraid he is most interested.

Merton nodded: "Yes, if the plateau is too high, the air is thin and there is a lack of oxygen. Since the air is thin, the natural air pressure is low. Therefore, Weichen speculates that if the air pressure is low, the boiling water boils less than 100 degrees. Therefore, we can't cook noodles and meat. We are in the plain, the air pressure is normal, and the boiling water is just 100 degrees. If we seal a pot and its cover, once the water boils, there will be great pressure The amount of water vapor volatilizes and increases the pressure in the pot. Similarly, the water in the pot will boil at a higher temperature. In this way, we can cook food faster and save firewood with this pressure cooker. "

The princesses and princes were confused about how to cook. Only Li Shimin heard the words. According to Merton's inference, there was really no problem.

"It's kind of interesting!" Li Shimin nodded. If the pressure cooker envisaged by Merton comes out, it will certainly benefit the people all over the world.

Li Tai shook his head and said, "as soon as brother Mo's pressure cooker comes out, I'm afraid Tubo will benefit the most!"

Merton shook his head and said, "the pressure cooker is indeed wonderful in the Tubo plateau. However, for thousands of years, Tubo has had its own eating habits. I'm afraid only a few Tubo dignitaries can use the pressure cooker. What really benefits me is the people of the Tang Dynasty."

Li Shimin nodded again and again and said, "OK, even if you pass this time, it doesn't count until the pressure cooker is really done."

Hearing the speech, Princess Changle couldn't help looking at Merton with adoring eyes. It seems that nothing can get Merton in her heart.

Li Shimin looked at Princess Changle's eyes and couldn't help feeling bored. Before that, his father was the person his daughter admired most. At present, his face was flat and said, "it's not short for you to leave the palace. Hurry back!"

"Yes, father!"

The crowd quickly bowed their heads and had to follow Li Shimin back to the palace.

"Congratulations to the emperor!"

Merton watched Li Shimin leave. He couldn't help but feel a burst of regret. I'm afraid this is the last time he and Changle met before marriage, but fortunately it's not long. They will be married in half a month, and they can get along day and night.

"Pressure cooker!"

In the Mo mansion, Lao Zhang's head and fish looked at Merton with unbelievable eyes.

Merton nodded and said, "if this pot can be made, the Mohist food city will have another bottom card."

The second fish frowned and said, "but young master, if the lid is sealed too tightly, it won't burst."

Merton glanced at Lao Zhang's head next to him and said, "that's why you and Uncle Zhang should do this together. We should not only ensure that the pressure in the pot is high, but also let the pressure release steam and reduce the pressure if it is too high."

Now the Mojia village has become formal. He doesn't need to do many things by himself. He directly says the requirements. He believes that Lao Zhang tou and Yu Er will surely create a real pressure cooker.

In the following time, the whole ink house roared continuously, and the sound of frying pan sounded from the backyard of the ink house. Yu Er and Lao Zhang ran out from time to time, sometimes with injuries on their faces and bruised by the exploding iron flakes, which made it difficult for the whole ink house not to notice.

"There's pressure, but I'm afraid I'll fry the pot before it's cooked." the second fish sighed.

Lao Zhang was not discouraged, but firmly said, "since the young master said this method can be done, it must be feasible. The young master has never made a mistake."

For Merton, Lao Zhang's head can be said to be blind self-confidence. To tell the truth, although Lao Zhang's skill is exquisite, he can only be called a craftsman at most. However, his biggest advantage is that once Merton issues the task, he will always study in this direction until he succeeds.

"Now that the fryer has been fried, it means that the sealing has been done. The rest is to keep how to release the excess pressure, and not to release too much!" Lao Zhang said.

Fish 2 nodded solemnly. This is the most difficult place.

"It's not easy. Since the gas in the pot needs to be discharged, just drill a hole in the pot cover!" suddenly Wu Meiniang's curious head stretched out. The two of them made such a big noise in the ink house, which naturally shocked Wu Meiniang. Now she is very interested in the ink technology of the Mohist School and naturally came together.

Lao Zhang said with a bitter smile, "Mei Niang doesn't know. Once the hole is drilled, the gas will be discharged and the air pressure in the pot will not rise."

"Then plug this hole again." Wu Meiniang didn't understand.

"Isn't that white drilling..." the fish said with a depressed face.

However, Lao Zhang suddenly had a flash of inspiration and said with great joy, "by the way, plug this hole. This is the pressure cooker the young master wants."

The second fish looked at Lao Zhang's head and didn't understand what he meant.

Lao Zhang was so excited that he couldn't help walking back and forth, dancing and saying, "blocking the hole is not to block the hole, but to press it with a heavy object. If the pressure in the pot is too high, it will naturally open. After the gas is released, the heavy object will naturally press the hole again. In this way, the domestic air pressure will certainly be maintained."

Yu Er suddenly realized that he was overjoyed. According to Merton's promise, if anyone developed new ink technology, he could enjoy a 5% commission, wouldn't it mean that he could also share in this pressure cooker.

"A heavy object alone may not be enough. Even we can use a spring to make a vent valve, which will certainly have a better effect." Lao Zhang's head touches the channel next to the class, but now the spring valve can't be made in a short time, so we can only use a heavy object to replace it first.

Soon, in the whole backyard, a sharp sound of gas overflow rang through the whole backyard.

Accompanied by a strong smell of meat, it floated throughout the ink house, which made people move their forefingers. People from the ink house gathered one after another.

"How fragrant!"

"The meat melts in the mouth!"

"Even the bones are soft. You can't cook them for a day."

……………………

With all the people in the ink house exclaiming, the pressure cooker was finally developed successfully.
