In fact, it was Li Eryi who came in and was shocked by the modernization of the yacht, but when Zhang Nan reminded him, Li Ercai remembered that his motorcycle was really similar to this boat, so Li Er didn't chase it deeply.

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

At first, Li Er, Empress Changsun and others thought it was a little interesting, but soon Empress Changsun felt bored, after all, women were not so interested in machinery.

"Your Majesty, the concubine feels a little boring, so it's better to let Yue'er accompany the concubine to go around this ship." Empress Eldest Sun spoke.

Li Er didn't think much about it, and also agreed to the request of Empress Changsun, after all, after Zhang Nan drove the boat, there was almost no superfluous action, it was completely the boat itself running, Zhang Nan didn't even have to control the direction, anyway, the sea was so big, there was no need to worry about not being able to drive, and Zhang Nan was almost driving in a straight line, and the end was boring and tight.

Empress Changsun left with Cui Yue, and as soon as Empress Changsun left, Li Er's words obviously increased.

"Qingquan, why is it that your ship can be made of steel, and the ship we are going to sail must be made of wood? Obviously, steel should make wood much stronger. Li Er asked strangely.

"Hey, this is really a complicated problem, how to say it, this problem is too complicated, so complicated that the ministers can't explain it, anyway, now we can't make it in the Tang Dynasty, Your Majesty, you can wait, maybe we can do it that year." Zhang Nan said with a smile.

To be honest, Zhang Nan really doesn't understand this problem, but Zhang Nan knows that it is not easy to make such a heavy steel float in the sea, and the steel will also carry out ionization reaction in the water, causing great loss to the steel.

What even Zhang Nan couldn't understand, Zhang Nan believed that no one in Datang could understand it now, so Zhang Nan could only wait for Datang's technology tree to automatically click. Or one day, after two famous Feng Shui masters of the Tang Dynasty have mastered high school physics, Zhang Nan feels that he can start studying these things.

After listening to Zhang Nan's words, Li Er didn't speak, just sat on the chair and didn't know what he was thinking.

At this time, Zhang Nan finally got out of the console, found a chair to sit down, and then took out three bottles of cold beer from the box at hand, and gave himself and Li Er and Qin Qiong a bottle.

Although this kind of separation between the driver and the console is expressly forbidden while driving, Zhang Nan doesn't care about this.

Seeing that there was nothing to drink among the four people, Du Ruhui said: "I said Qingquan, how can this still be treated differently, why does Shubao have to drink, but I don't have it?" I haven't eaten a drop of water for so long. ”

When Zhang Nan heard this, he first poured himself a big sip of beer, and then said cheaply: "Eh, my Lord Du, it's not that I don't want to give you a drink, this thing is wine, you are a sick person named by the emperor to cultivate, how can there be a reason to drink when you are sick in this world?" ”

After speaking, Zhang Nan poured another big sip of wine into it, and then said with a "ha" sound: "But it's really a blessing to be able to drink cold beer on such a hot day, don't you think, Your Majesty?" ”

After listening to Zhang Nan's words, Li Er knew that Zhang Nan was joking with Du Ruhui, and it was rare to put away his shelf, and said with a smile: "That's right, Keming, your health is not good, don't drink, this wine is not good for your body." ”

"Yes, yes, the emperor and Qingquan are right, this wine, let's drink it, Keming, you better drink water." Qin Qiong also said with a smile after hearing this.

"What, Your Majesty, the minister's health has long been fine, how many times have the minister told you that the minister can go back to the court, but the emperor has never let you." Du Ruhui also said helplessly.

Du Ruhui is actually an out-and-out workaholic, not only has a strong ability to work, but also a workaholic who has a sense of responsibility and adds life to himself.

However, Li Er is not the black-hearted boss of later generations.

"Keming, you are my right-hand man, I would rather let you be at home than let you joke with your body anymore." Li Er also became serious when he talked about this issue, after all, the last time 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 fight the world, Li Er and Du Ruhui are not only monarchs and ministers, but also good friends.

When Zhang Nan saw Li Er's appearance, he also quietly came to Li Er's side and said: "Your Majesty, in fact, the minister's body is also very uncomfortable, Your Majesty, don't you force the minister to do this or that?" ”

As soon as Li Er heard this, he hit Zhang Nan on the back, although it didn't hurt, but the sound was very loud.

"Hmph, Qingquan, your body is as strong as a cow, I know that you are a donkey who doesn't walk without whipping, if I hadn't forced you, Datang would have developed so fast?" Li Er pursed the corners of his lips and said.

"Eh, you're dying, your emperor has inflicted internal injuries on your ministers, and you're going to die." As he spoke, Zhang Nan slipped out of the chair one by one, pretending to be so true that Li Er almost believed it.

"Okay, you don't have to act, don't you feel like getting a bottle of wine for Keming? Today, I was happy, so I allowed Keming to take two sips, and I felt that this beer was no different from water, and it was not in the way to drink a bottle. Li Er commanded.

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

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

"Okay, okay, it's okay to sit here, why don't you sing a song to me." Li Er didn't know which way to smoke, so he suddenly made this request.

After listening to Li Er's words, Zhang Nan was shocked, let me sing? You really think of me as a little swallow.

Suddenly, Zhang Nan's mind appeared in "Huanzhu Gege" when Qianlong took Xiaoyanzi and Ziwei out on patrol, his favorite entertainment was, "Xiaoyanzi, Ziwei, you two sing a song to me." ”

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

"Your Majesty, what do you want to hear? There aren't many songs in the courtiers' meeting. Zhang Nan asked cautiously.

Zhang Nan really doesn't have many songs, and most of them are love songs, if he gives Li Er a hand of love and love in this cockpit, Zhang Nan estimates that Li Er can hang himself on the bow of the boat to dry.
