There are a lot of water and wine collected. After all, there are several restaurants in Luoshan County alone. These wines are placed in the backyard of the yamen.

"Your Highness, what do you want these water and wine to do?" Meng Fanchao, the secret guard beside Zhu Cixuan, couldn't help but ask.

Wangcai thought he was right: "Drink, Your Highness wants to boost morale and reward the soldiers with wine."

As a dog eunuch, Wangcai’s biggest hobby is drinking. As an incomplete man, the eunuch has no chance of food and sex, so he counts on food and sex.

The winemaking technology in the Ming Dynasty was quite mature, and the wine brewing and distillation technology was greatly improved. Prepared wines and tonic wines were produced using rice wine and soju as raw materials. The types of wines increased compared with the Yuan Dynasty, with barley wine, and fruit wine not only wine, but also date wine, mulberry wine, lychee wine, etc.

The most representative of rice wine and soju are Shaoxing wine and Shanxi Fenjiu. In the Song Dynasty, Shaoxing wine industry was very developed and produced famous wines such as bamboo leaf green. In the Ming Dynasty, Shaoxing wine industry continued to flourish and its wine products were transported and sold to the capital. There was no ban on wine in the Ming Dynasty and no tax was imposed on brewing, so the wine industry developed greatly.

However, for brewing high-level wines, there is still a lack of technology. This is a matter of no choice due to the limitations of the times. The wine with the highest degree is also Nan Shaojiu. Nan Shaojiu produced in Shaoxing is the lees of the filtered rice wine. It is made of distilled and recycled. It is called "龙育" or "Shaojiu". The wine is strong and particularly attractive.

Wine is a good thing. Wangcai couldn't help but lick his tongue, and there was a lot of good wine in it.

Wangcai thought he could drink a lot, but Zhu Cilang said coldly: "I am passing on the military order of this palace. Those who drink wine will be punished twenty rods."

Then the smile solidified on Wangcai's face. How could he have thought that the prince turned against him and said that he would turn against him. His highness brought these water and wine, but he didn't drink them at all.

"Then, your highness, what are you going to use for? "Wangcai couldn't help asking.

“Purification.”

Wangcai and Meng Fanchao looked at each other, and they didn't understand what purification means.

Fortunately, Zhu Cilang continued: "Meng Fanchao, go and tell Miss Ling, you go and find several shopkeepers who make soybean wine in the city."

There are still two workshops specializing in making soju wine in Luoshan County. One of the short and fat shopkeepers is named Tian and the other one is named Lu.

The two of them came to the yamen and were really trembling when they saw Zhu Cilang. Their salmon was originally collected by the yamen. This time they were called to the yamen, and they didn't know what was wrong. This was the crown prince of the dynasty. They had never seen any official as big as a royal relative in their half-life.

"Shopkeeper Tian, ​​Storekeeper Lu, right?" Zhu Cixuan asked, looking at the two people kneeling on the ground.

"The villain is, His Highness, thousands of years old."

Zhu Cilang said "Yes": "When you came, you also saw the water and wine collected from the yamen. I ordered you two families to do one thing. Aren't you the sour wine? Take the wine back and continue to purify it for me. What I want is the most purity spirit."

In this era, there is already distillation technology. Soju can be increased from 3 to 10 degrees to 50 degrees to 60 degrees. It is not that they do not know how to continue to purify, but that the wine will lose its drinking value after it continues to purify. In addition, people in this era do not know the use of alcohol.

The alcohol that is constantly distilled and purified to 70 to 80 degrees is not drinkable.

Wangcai and Meng Fanchao didn't understand the purity of Zhu Cilang. However, shopkeeper Tian and shopkeeper Lu understood, but they were also shocked.

They thought that His Highness the Crown Prince did not know how to drink. Manager Tian was brave and said tremblingly: "When you go back to His Highness the Crown Prince, you can't drink this sour wine if you steam too many times."

Zhu Cilang said coldly: "I say it again, what I want is pure. The purer the wine, the better. It is not something you want to drink, it is clear enough."

It's clear enough now that the two shopkeepers' gallbladders are ruptured, so how dare they make any suggestions? Dongdongdong kowtowed a few times, indicating that they would have completed the instructions of His Royal Highness the Crown Prince.

Zhu Cilang nodded slightly satisfied: "Okay, go down."

Zhu Cixuan wanted to purify alcohol because he wanted to use it as fuel. He wanted to make a hot air balloon. Only by using the hot air balloon can he break into the enemy and rescue Hongniangzi and Li Yan.

Hot air balloons are a new product of this era, and no one has seen what this thing is. Zhu Cixuan has sufficient reason to believe that once the hot air balloon appears in the enemy camp, let alone those bandits, even Li Zicheng will be scared out of his courage. Maybe they thought it was the gods who were furious.

Only by riding in a hot air balloon with alcohol as fuel can the balloon rise. After arriving at the enemy camp, throw a few earthy gunpowder into the air, first blow the bandits up to death. Then rescue Hongniang and Li Yan, and then escape in a hot air balloon.

Hot air balloons are condescending and you must act as soon as possible before the enemy can react. The problem is that making hot air balloons is a very complicated technical job.

First of all, fuel is a big problem. Ordinary fuel is simply not enough to make hot air balloons rise. In this era, there was no gasoline or diesel, and alcohol was the only choice. Although alcohol was extremely expensive.

This is not counting. In addition to alcohol, hot air balloon materials are also important. They must be refractory materials, and their quality is light. Zhu Cixuan has thought of many ways, but only oil paper is light enough.

But oil paper also has a huge disadvantage, that is, it cannot be fire-proof. Moreover, oil paper is too low-quality and cannot be used on hot air balloons. Fabric is the best choice, but the Ming Dynasty did not create air-impermeable fabrics. In addition, flame retardant fabrics are also a big problem. These are all problems that Zhu Cixuan needs to solve one by one.

Zhu Cixuan didn't tell anyone about his purpose, even if he told them. These people couldn't understand, so he could only do it himself and extract the alcohol first before talking about it.

Zhan Yunpeng and the others went to cut some bamboo, and Zhu Cixuan decided to use bamboo as a frame. After all, the bamboo is lighter in weight, and these bamboos must also be fire-proofed.

In addition, the shopkeepers of several cloth shops in Luoshan County and the bricklayer were found by Zhao Yun from the Tiger Army. These people were also nervous when they went to the yamen.

There are not many ordinary people who are not afraid of officials, especially these cautious and law-abiding people. Although it was the summons of His Royal Highness, they all felt confident and did not know whether it was a blessing or a disaster. Even many people had already explained their funerals at home on the way they came.

"Don't be afraid, I am not a human-eating tiger. I asked you to come here to ask you shopkeepers of the cloth shop. Do you know which kind of cloth has the worst permeability?"

Even when you were in ancient times, as a time traveler, you knew some scientific knowledge. However, theory and practice have always been different.
