Everyone sighed in disappointment. A thousand years is too long, and they probably won't see it.

Merton said confidently: "Although it is impossible to achieve it at present, if the Mo family keeps researching, it will definitely shorten the process by several times." ”

"That was hundreds of years later." Li Shimin sneered, he didn't want to let Merton get away with it so easily.

Merton gritted his teeth and said, "If Your Majesty wants to see the results immediately, Weichen also has one." ”

"Oh!" Everyone couldn't help but look at Merton.

"Pressure cooker!" Merton said word by word.

"What is a pressure cooker!" Everyone looked at Merton in confusion.

Mo Dun said proudly: "I wait to cook rice on weekdays, as long as the water in the pot boils, it will not take long to cook, and the Mo family will count the water freezing as zero degrees, and the water boiling as 100 degrees." ”

Li Tai's eyes lit up, and he hurriedly kept this in mind.

Merton continued: "However, when Weichen was on the western expedition, he heard a strange news, that is, when the Southern Route Army led by General Hou and General Li was marching on the Tibetan Plateau, they wanted to set up camp and cook rice, but they found that the water was boiling, but they couldn't cook the noodles and meat at all, and tested the water temperature with their hands, which was far less hot than the boiling water in the plains. ”

"How could such a miracle happen?" Li Shimin said strangely.

Merton said solemnly: "This is the personal experience of tens of thousands of soldiers, how can Wei Chen say that since he found that it was not cooked, many soldiers mostly ate dry food or barbecued meat directly, which did not affect the march. ”

Li Shimin nodded, so many people have experienced it personally, and I think that Modon will definitely not lie here.

"Does this atmospheric pressure have anything to do with it?" Li Tai asked puzzled. Of all the people, he was probably the most interested.

Merton nodded and said: "Yes, the plateau is too high is the air is thin and lacks oxygen to have altitude sickness, since the air is thin, the natural air pressure is low, so Wei Chen speculated that the air pressure is low, then the boiling water is less than 100 degrees to boil, so I can't cook noodles and meat, I am waiting in the plains, the air pressure is normal, the boiling water is exactly 100 degrees, if I wait to seal a pot and the lid, once the water is opened, there will be a large amount of water vapor volatilization, so that the pressure in the pot increases, in the same way, the water in the pot will definitely boil at a higher temperature, In this way, wouldn't it be faster for us to use this pressure cooker to cook food, and it would be more economical to save firewood. ”

Where did the princesses and princes know how to cook such a rough job, they couldn't help but be confused, only Li Shimin heard this, according to Merton's inference, there was indeed no problem.

"It's kind of interesting!" Li Shimin nodded and said, if the pressure cooker conceived by Merton comes out, it will definitely benefit the people of the world.

Li Tai shook his head and said: "As soon as Brother Mo's pressure cooker comes out, I'm afraid the biggest benefit is still Tubo!" ”

Merton shook his head and said: "The pressure cooker is indeed wonderfully used on the Tubo Plateau, but for thousands of years, Tubo has had its own eating habits, and the pressure cooker is probably only used by a few Tubo magnates, and it is my Tang people who really benefit." ”

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

When Princess Changle heard this, she couldn't help but look at Merton with adoring eyes, and it seemed that nothing in her heart could be difficult to get Merton.

Li Shimin looked at Princess Changle's eyes, and couldn't help but feel sullen for a while, before that, the person his daughter admired the most was his father, and at the moment, his face was blank and said: "The time to get out of the palace is not short, let's go back quickly!" ”

"Yes, Father!"

Everyone hurriedly bowed their heads, and their momentum was weak, so they had to follow Li Shimin back to the palace.

"Congratulations to the emperor!"

Merton watched Li Shiren leave, and couldn't help but feel a pity in his heart, I'm afraid this is the last time he and Changle will meet before marriage, but fortunately, it is not long, and they will get married in half a month, so they can get along day and night.

"Pressure cooker!"

In the ink mansion, Lao Zhangtou and Yu Er looked at Merton in disbelief.

Mo Dun nodded and said, "If this pot can be made, the Mo Family Food City will have another hole card." ”

Yu Er frowned and said, "But young master, if the lid of the pot is sealed too tightly, it won't burst open." ”

Morton glanced at the old Zhang Tou next to him and said: "That's why this problem is left to you and Uncle Zhang to do together, not only to ensure that the air pressure in the pot is high, but also to let the air pressure once it is too high, take the initiative to release steam to reduce the air pressure." ”

Now that Mojia Village has become formalized, many things do not need him to do it himself, and he directly said the requirements, he believes that Lao Zhangtou and Yu Er will definitely build a real pressure cooker.

In the next time, the entire Mofu rumbled continuously, and the sound of a fryer sounded from the backyard of the Mofu, and Yu Er and Lao Zhangtou ran out from time to time with a disgraced face, and sometimes they were even injured on their faces, and they were bruised by the exploding iron pieces, making it difficult for the entire Mofu not to notice.

"This pressure is there, but if you don't wait for it to be cooked, I'm afraid you'll be in the pan." Yu Er lamented.

Lao Zhangtou was not discouraged, but said firmly: "Since the young master said that this method can be done, then it must be feasible, and the young master has never made a mistake." ”

For Merton, Lao Zhangtou can be said to be blindly confident, to be honest, although Lao Zhangtou is highly skilled, he can only be called a craftsman at most, but its biggest advantage is that once Merton issued a mission, he will continue to study in this direction until he succeeds.

"Since the frying pan has been built, it means that the sealing aspect has been seated, and all that remains is to keep how to release the excess pressure, and not too much!" The old man is embarrassed.

Yu Er nodded solemnly, this is the most difficult part.

"It's not simple, since the gas in the pot needs to be discharged, just drill a hole in the lid!" Suddenly, Wu Meiniang's curious head stretched out, the two of them made such a big move in the Mo Mansion, which naturally alarmed Wu Meiniang, she now has a great interest in the Mo family's ink skills, so she naturally came over.

Lao Zhangtou smiled bitterly: "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 just plug this hole again." Wu Meiniang was puzzled.

"Isn't that a hole drilled for nothing......" Yu Er said with a frustrated face.

However, Lao Zhangtou suddenly had a flash of inspiration, and suddenly said in ecstasy: "By the way, plug this hole, this is the pressure cooker that the young master wants." ”

Yu Er looked at Lao Zhangtou in confusion for a moment, not understanding what it meant.

Lao Zhangtou couldn't help himself excitedly, and walked back and forth and danced with his hands: "Plugging this hole is not to block this hole, but to press it with a heavy object, if the pressure in the pot is too large, it will naturally be pushed open, and after the gas is released, this heavy object will naturally press this hole again." In this way, the air pressure in the country will definitely be maintained. ”

Yu Er suddenly realized, and couldn't help but be ecstatic in his heart, according to Merton's promise, if anyone who researches a new ink technique can enjoy a commission of five percent, doesn't that mean that he can also share a share of this pressure cooker.

"A heavy object alone may not be enough, and we can even use a spring as a bleed valve, which will definitely work better." The old head touches the bypass channel, but now the spring valve can't be done in a short time, so it can only be replaced by a heavy object.

Soon, in the entire backyard, the sound of sharp gas overflowing resounded throughout the backyard.

With a burst of rich meat aroma, it wafted throughout the Mo Mansion, making people can't help but move their appetites, and everyone in the Mo Mansion gathered one after another.

"It smells so good!"

"This meat melts in your mouth!"

"Even the bones are soft, and I can't cook them like this even if I cook them for a day."

……………………

With the exclamations of everyone in Mofu, the pressure cooker was finally developed.
