In fact, Li Eryi was shocked by the modernization of the yacht when he came in. However, when Zhang Nan reminded him, Li Er remembered that his motorcycle was really similar to this ship, so Li Er did not pursue it in depth.

Zhang Nan quickly started the yacht, drove away from Taicang Wharf, and headed towards the vast sea.

At first, Li Er, Empress Changsun and others found it interesting, but soon Empress Changsun felt bored. After all, women are not that interested in machinery.

"Your Majesty, I feel it's a bit boring. Why don't you let Yue'er accompany me to the boat?" Empress Changsun said.

Li Er didn't think much about it and agreed to Empress Changsun's request. After all, Zhang Nan had almost no unnecessary movement after driving the boat. It was all the boat running by itself. Zhang Nan didn't even have to control the direction. Anyway, the sea was so big, so there was no need to worry about not being able to drive. Moreover, Zhang Nan was almost driving in a straight line, and the end was boring and tight.

Empress Changsun took Cui Yue away. As soon as Empress Changsun left, Li Er said more obviously.

"Qingquan, why can you make all your ships of steel? You have to make the ships we want to sail out of sea with wood? The steel must make the wood much stronger." Li Er asked strangely.

"Hey, this is really a complicated question. How can I say it? This question is so complicated that I can't explain it. Anyway, we can't create it now. Your Majesty, you can wait. Maybe we will do that year." Zhang Nan smiled.

To be honest, Zhang Nan really doesn't understand this problem, but Zhang Nan knows that it is not easy to make such heavy steel float in the sea. Steel will also undergo ionization reactions in water, causing great losses to steel. Although Zhang Nan studied science, Zhang Nan has not yet learned chemistry until now.

Zhang Nan believes that no one can understand the Tang Dynasty, so Zhang Nan can only wait for the Tang Dynasty to automatically click on the science and technology tree. Or one day, after two famous Feng Shui masters of the Tang Dynasty completed high school physics, Zhang Nan felt that he could start studying these things.

After hearing Zhang Nan's words, Li Er didn't say anything, just sat on the chair and didn't know what he was thinking about.

At this time, Zhang Nan finally left the operating table, found a chair to sit down, and then took out three bottles of cold beer from the box at hand, giving him, Li Er and Qin Qiong a bottle.

Although this kind of separation between the driver and the operating table is explicitly prohibited during driving, Zhang Nan doesn't care about these things.

Seeing that there was nothing to drink among the four people, Du Ruhui said, "I said Qingquan, why are you treating this differently? Why do you have the best drinks for the Uncle Bao? I don't have them? I haven't gotten the water for so long."

When Zhang Nan heard this, he first fed himself a big sip of beer, and then said in a low voice: "Oh my Lord Du, it's not that I don't want to give you drinks. This thing is wine. You are a patient named by the emperor. How can you drink alcohol in this world if you get sick?"

After saying that, Zhang Nan took another big sip of wine, then said with a "ha" sound: "But it's really a blessing to be able to drink cold beer on such a hot day. Do you think so?"

After hearing Zhang Nan's words, Li Er knew that Zhang Nan was joking with Du Ruhui, and he put away his airs with a rare smile and said, "That's right, Keming, you are in poor health, so don't drink alcohol. This alcohol is not good for your health."

"Yes, yes, the emperor and Qingquan said it well. Let's drink this wine. Keming, you should drink water." Qin Qiong also said with a smile after hearing this.

"What, Your Majesty, I have been well, I have told you how many times I can go back to court, but you have never allowed me." Du Ruhui also said helplessly.

Du Ruhui is actually an absolute workaholic. He is not only a strong work ability, but also a responsible workaholic who increases his life. If he is put in future generations, such employees will have to make the bosses break their heads.

However, Li Er is not a bad boss in later generations.

"Keming, you are my right-hand man. I would rather let you work at home than let you joke about your own body." Li Er also became serious when he talked about this issue. After all, when Du Ruhui was critically ill, Li Er really cried, which shows Du Ruhui's position in Li Er's heart. After all, this is an old minister who accompanied him to conquer the world. Li Er and Du Ruhui are both kings and ministers and good friends.

When Zhang Nan saw Li Er's appearance, he quietly came to Li Er's side and said, "Your Majesty, I am actually very uncomfortable. Your Majesty, don't force me to do this or that?"

When Li Er heard this, he hit Zhang Nan's back with a hammer. Although it didn't hurt, the sound was very loud.

"Hmph, Qingquan, your body is as strong as a cow. Do I know that you are just a donkey that doesn't leave without whipping. If I hadn't forced you, the Tang Dynasty would have developed so quickly?" Li Er said with a curl of his lips.

"Oh, I'm alive. Your Majesty, you've been injected with internal injuries to me. You're going to die." As he said that, Zhang Nan kept slipping out onto the chair. The real appearance of pretending made Li Er almost believe it.

"Okay, no need to act anymore. Don't you feel like you're going to get a bottle of wine for Keming? Today I'm happy, so I'll give Keming a few sips. And I think this beer is no different from water, so drinking a bottle is not a problem." Li Er ordered.

Hearing Li Er say this, Zhang Nan also stood up with a smile, took a bottle of beer for Du Ruhui, opened the bottle cap and handed it to him.

Unexpectedly, Du Ruhui took the beer but did not give Zhang Nan a good look, as if he was silently protesting Zhang Nan's different treatment just now.

"Okay, okay, I'm idle while sitting. Why don't you sing a song for me? "Li Er suddenly made this request if he didn't know where to draw.

After listening to Li Er's words, Zhang Nan looked shocked and asked me to sing? You really treat me like a little swallow.

Suddenly, Zhang Nan's mind appeared in "My Fair Princess" when Qianlong took Xiaoyanzi and Ziwei on a tour. His favorite entertainment activity was, "Little Yanzi, Ziwei, you two sing a song for me."

Zhang Nan didn't expect that one day, such a bloody thing would be his turn to his head.

"Your Majesty, what do you want to listen to? There are not many songs in my memory." Zhang Nan asked carefully.

There are not many songs that Zhang Nan can do, and most of them are love songs. If you give Li Er a love in this cockpit, Zhang Nan probably will be able to hang himself on the bow of the boat and dry it.
