Zhu Biao chose to stay, stay one more day, and go to Mengcheng County tomorrow.

He decided to help more people along the way, and he could manage one by one, and he couldn't come back during the Chinese New Year anyway.

Longkangji was originally a county, which lasted until the Song Dynasty, and then the war, the Yuan Dynasty ruled, and the county was removed.

As long as the Ming Dynasty continued to develop sailors and encouraged inland waterway shipping, this place would inevitably develop again.

The procession stopped, and the nearby vegetable sellers were the first to eat, and the prince's team sent people and cars to pick vegetables from their fields.

Weigh immediately after picking, and settle the money once you pick it.

Jiayuan watched from afar, Zhu Fan went over and told them to send a car to their house to pull vegetables, and they hurriedly packed up their things and took people on the road.

Zhu Biao stood by the river and looked at the opposite riverbank: "Isn't it better to build a bridge?" ”

The lieutenant commander who accompanied him took a telescope to take a look: "The height of the bridge should be high, so that it is convenient for ships to pass through." ”

Zhu Wentian looked at it from the other side, he knew what the bridge was like at the location here, there were several.

However, the river was much narrower than it is now, and at the same time, the flow became smaller, and shipping was basically gone, and only economical ships remained.

At this moment, people with good water quality go down to the river to touch the mussels, and people with bad water in other small rivers go to touch them.

The people in the team have become accustomed to walking along the way to find food, especially the artisans.

At first, they thought that following the team, there would be roads and supplies, and the speed would be fast.

It turned out that the situation was not right, and from the next day, the team stopped and stopped, hunting game and netting again.

Now the net fish are non-stop, and the idle people touch the mussels, and the mussels bigger than the palm can be seen everywhere.

The children who came to get snacks also helped, and when the people saw that His Royal Highness the Prince's team touched the mussels, they went to the house to fetch chickens and ducks to give to the prince and the king of Qin to eat.

"Your Royal Highness the Prince, the river mussels are not delicious, the bigger they are, the harder they are to chew, they can't bite at all, like chewing branches, unless they are cooked with a lot of firewood."

Zhang Luming, the lieutenant here, came over, carrying a rooster in his hand, and persuaded Zhu Biao not to eat river mussels.

Zhu Biao recalled and said to Zhang Luming: "The river mussels eaten in this palace are not difficult to chew, Zhu Lichang? ”

"Go back to His Royal Highness the Crown Prince and ask, that's because the beating method taught to Guanglu Temple by Xiaqiu Village broke up the mussel meat.

Ordinary people don't know, just throw it in a pot or jar to boil, and put a little salt to fill the hunger.

Or if it is cooked for a long time, it can also cook the meat badly, which does cost firewood, and the people are unwilling to eat it. ”

The lieutenant knows the reason and the way it is operated. He spoke more respectfully than usual, with outsiders there.

"Zhang Lichang, you can ask the people to watch the production method next to you and go home to try it." Zhu Biao's head.

As for the poultry sent by the people, they should not be used, but they should be taken back to lay eggs or eaten by themselves.

"In fact, some utensils can be made and placed in places where there are mussels, and the mussels can be cooked for the people, and the price can be charged according to the weight of the mussels. Your Highness, please come with me. ”

The lieutenant decided to take another good thing out, and this time he traveled, and Xiaqiu Village brought all the skills that could be taken out.

Zhu Biao and Zhu Fan followed curiously and came to their own small camp in Xiaqiu Village.

Zhang Luming saw that no one stopped him, so he also came here with him.

The lieutenant looked at the number of the car, picked the number four, and took out a pot with a lid from it.

"Your Royal Highness, please see, this pot is called a pressure cooker, and a pressure test table is used for testing after manufacturing.

Nowadays there is only a simple pressure relief valve, and when the pressure in the pot reaches a certain level, it will bounce up and bubble to prevent the pot from exploding.

Since it is necessary to make a steam engine, it is necessary to know the pressure, and at the same time it is easy to take the principle of a steam engine to make a pressure cooker.

The village made a pressure gauge and tested the water pressure, using the depth of the water instead of the air pressure to obtain the pressure gauge data.

Water vapor ......"

The chief said a lot, introducing the principle of pressure cooker, as well as the relationship between air pressure and water boiling.

Zhu Biao and Zhu Fan are trying to remember, the two always deal with the children in Xiaqiu Village, have learned some knowledge, and now they can keep up.

Zhang Luming, the lieutenant chief next to him, heard that his head was buzzing, and he dared to guarantee that he knew every word of what the other lieutenant chief said, and he put it together......

"Captain, isn't this how many of the delicatessen in the deli are made?"

Zhu Fan remembered that the deli was very fast in producing cooked food, especially pig's head meat and pig's trotters.

The meat cooked in the store is soft and delicious, and it takes a short time.

Zhang Luming didn't say anything, knowing that what His Royal Highness King Qin said was not himself.

"What His Highness said is good, that is a high-pressure barrel, and you can do a lot at one time." The lieutenant nodded.

"Captain, it's not affected by the weather outside?" Zhu Biao asked.

"Exactly!" The lieutenant continued to nod.

"In this case, when it is used in the northwest, it can be cooked when it is cooked, but I heard that the rice cooked there is not cooked, so it can only be fried and fried."

Zhu Biao thought of the role of the pressure cooker in front of him, to the northwest, where the place is high, according to the chief of the province, the air pressure is low, and the boiling temperature of the water is low.

So before the food is cooked, the water boils and the temperature does not rise.

"That's right." The lieutenant still nodded.

"Make a pot and see." Zhu Biaobei saw it with his own eyes, and at the same time, a pot was also prepared next to him, and the two pots were compared.

"Is chicken stew?" The lieutenant asked, by the way, looking at the in Zhang Luming's lieutenant hand.

"Yes!" Zhu Biao also looked over.

Zhang Luming offered the chicken, and the children slaughtered it, picked up the chicken's blood, removed the chicken feathers, and then divided the chicken into two from the middle.

However, the most difficult to cook chicken head is placed in a pressure cooker, plus ingredients, ginger slices, and green onions, and the two pots are placed on the stove at the same time.

"If the cooking time is much shorter, you can save firewood, you can see the money and fees charged for firewood?"

Zhu Biao stood next to the two pots and said what the chief had mentioned before.

How much is the right amount of money to charge by putting a pressure cooker on the bazaar, processing mussels for others, one pot at a time?

"Its practical vats are good, there are them in the car, but they can't be left for the people, this is our emergency use.

If it is feasible, and then send it to the people, His Highness can write back and ask the village to provide technical and safety testing.

The pressure test must be passed, otherwise the air leakage is good to say, and it will blow up and kill people. ”

The lieutenant first made it clear that the car can't be given, and the reason why it is not used now is that it is not needed.

The stewed chicken is still slowly stewed in a normal pot, especially when making braised pork.

Zhu Fan came to the side of the pressure cooker, stretched out his fingers and slowly moved towards the lid of the pot, and immediately retracted his hand after touching it.

"Hot, steely? How did you come to do this? ”

"Forging, using molds, and steel columns, after being raised, they fall down and forge, and if you cast, you are worried about trachoma."

"I can't think of it, let them go to the village to learn when the time comes, and teach them the low-tech ones, the valve on the top is the most important, right? No need to teach. ”

Zhu Fan couldn't look at the whole manufacturing process now, so he simply didn't think about it, otherwise he would be tired.

It's late for the third today, and the dogs downstairs don't know which ones keep barking, alas!
