Why didn’t Zhu Cilang come back? It was because he had a great time talking with Tang Ruowang at Zuixianlou.

When he was in college, Zhu Cixuan was hiding in the bed in the dormitory playing with his mobile phone, so he didn't shamelessly ask the brothers on the lower bunk to speak. Since he was bitten by a five-step snake, he came to the Ming Dynasty in this parallel world without borrowing a step to speak.

Here, the mountains and rivers are still the same, and the Ming Dynasty is still the same, but everything has changed. The mountains and rivers are still the same, and the rivers are still the same river.

But here, there is no trace of modern civilization. Zhu Cixuan has truly adapted to a boring day without wifi, mobile phone, computer or game.

Zhu Cilang, who was almost crazy, started his nonsense journey. First, he took the eunuchs from the East Palace to cut down a crooked tree on the coal mountain, and then went to borrow money from his grandfather...

Fortunately, although the Ming Dynasty is still shaky, at least it has been given a mouthful of life-sacrificing soup. In a short period of time, it can still take a breath.

But, how lonely it is, how empty it is, how cold it is, how cold it is, how empty it is, the only son is in the peak, the cold wind keeps blowing, my loneliness, my loneliness, who can understand me...

Johnson Chan could understand that at least, in some simple theoretical chemistry knowledge, the two met too late.

Zhu Cilang finally found a partner to talk to and finally found a confidant. At least, he could find someone to discuss with his mind.

The same is true for Joshua Chan. In this turbulent era of the Ming Dynasty, although there were many like-minded friends, such as the famous Xu Guangqi.

Johnson Tang once assisted Xu Guangqi in completing the voluminous "Chongzhen Calendar", a total of 46 types and 137 volumes. The compilation of "Chongzhen Calendar" marks the trend of Chinese astronomy entering the development of world astronomy from then on.

Unfortunately, Xu Guangqi had already passed away at this time. Joshua Tsang never had any friends again. Although Emperor Chongzhen still trusted him, at the Imperial Heaven Supervisory, Joshua Tsang, as a representative of Western academics, was often excluded by pedantic and conservative officials.

Unexpectedly, the prince in front of me could have a great conversation with me. This made Joshua Chan overjoyed. As a missionary who came to China, Joshua Chan thought he knew everything about astronomy and geography.

But after talking with Zhu Cilang, Tang Ruowang suddenly knew what it means to have someone else outside the heavens. His Royal Highness's knowledge is as vast as the sea.

Especially for research such as astronomy, calendar, physics, chemistry, etc., they can be called gods. Zhu Cilang's casual words are enough for him, Johnson Chan to study for half his life.

Awesome, amazing. There were such masters in the Ming Dynasty. How could Tang Ruowang not be surprised? But what disappointed him was that the prince seemed to be only interested in firearms. Whenever the two talked about other topics, Zhu Cixuan always explained a few words lightly, and then talked about firearms again.

"Wangcai, Sun Wangcai, come with me!" Zhu Cilang's voice sounded from the private room of Zuixianlou.

The dog-legged boy Wangcai immediately opened the door and arched in like a dog: "What are your instructions?"

"Pen, paper, send it quickly."

The table that was originally filled with dishes was cleaned up. At this moment, there were several teapots and tea cups on the table.

Sun Wangcai responded and hurried downstairs. Meng Fanchao, the secret guard at the door, couldn't hold on anymore, so he sat down and nodded constantly.

Wangcai went down to borrow paper and pen from the shopkeeper, and the shopkeeper could no longer hold on. It was already time, and it was time for them to close. At this time, the Zuixian Tower had already closed, and the update outside was prompting that it was three o'clock in the morning, which means it was past three o'clock in the morning.

In addition to the man who could not afford to offend the upper floor, there was another person in the hall downstairs. That was the down-and-out scholar. There was a jar of wine in front of his table. The scholar seemed to be sleepy and was still drinking and drinking. He should thank Zhu Cilang. If it weren't for Zhu Cilang's table upstairs, he would have been driven out by the shopkeeper long ago.

People do business and don’t let people sleep. Even if they are donkeys from the production team, they have to have rest time. Besides, they will have to open tomorrow.

Therefore, when Wangcai came down to borrow paper and pen, the shopkeeper found paper and pen, and smiled tactfully: "I'm sorry, the customer, all the shopkeepers went to bed. The shop is too negligent, but the shop is too negligent."

Businessmen can distinguish people. Judging from the wealth of Zhu Cixuan and his group, they must be a royal relative. Not to mention that there is also a bearded foreigner who looks like a slut, even in Beijing, foreign missionaries are rare.

You can't afford to provoke such people in Beijing. If you sneeze, you may spray a royal relative's face. Even if the shopkeeper is dissatisfied, he will not dare to show it on his face.

Besides, such a generous and generous official is his own parents for food and clothing. He is a restaurant owner, so he naturally dares to neglect him.

The words that the guest officials were neglected were actually a tactful statement that they should have closed long ago. You see, it’s almost dawn, can you leave quickly?

Sun Wangcai felt a little guilty: "I'm sorry, the shopkeeper, my master has something to discuss, which has delayed your rest. This is not worthy of respect, so my master rewards you."

Wangcai gave him a ingot of silver, and the shopkeeper immediately became surprised: "Oh, this is too much, too much."

I became a little impatient: "Just take it for you, there is no such a lot of nonsense. My master may have to eat and drink later, and I have to worry about you."

The shopkeeper who received the silver reward immediately became lively like chicken blood: "Don't worry, please give me some instructions if you have anything to do."

Wangcai nodded and glanced at the scholar in the corner. He didn't have to worry about it now, and he went upstairs with paper and pen.

In the private room upstairs, Zhu Cixuan unfolded paper and pen on the table: "Parent Sun, go and take me the door bolt."

With paper and pen, unfortunately there are no drawing tools, such as compass, rulers, triangles, etc., so I had to use the materials locally. Zhu Cixuan used the door bolt as a ruler and touched a thick bowl to draw circles: "Tang Ruowang, come on. This is the gun rule set by the palace, and the ruler made by the gun ruler. Using this method, you can aim the Red Cannon and increase the hit rate of the cannon."

The hit rate of the Red Cannon is extremely low, and it is easy to miss unless it is an excellent gunner. The aim of the cannon is a slight mistake. A small error on the aiming ruler will greatly reduce the shooting accuracy.

Especially the longer the distance, the greater the error is. It can be said that it is almost entirely confusing to apply it on the battlefield.
