I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

In fact, it is not surprising that Liu Tan was surprised. When designing the water outlet button, in order to be able to use it for a longer time, he went through many experiments and modified the details bit by bit. Finally, he was sure that it could withstand long-term use before the finished product was produced.

This long-term use means that even if it is used twenty times a day, it can be guaranteed for at least three years.

He has no way to guarantee more, because the experiment time is too short, and there are no machine experiments these days. He relies on manual experiments. If he wants to test for a longer period of time, he will need a longer experiment time.

But is this enough?After all, when it comes to the royal family, the toilet must be dedicated to someone. For example, if it is given to Liu Shi, it must be used by him alone. In this way, as long as there are no major accidents, it will be no problem to use it for a few years.

Even if he once said that he might have to sell accessories to make money, it was just self-deprecating, let alone the things Liu Che and Liu Ju used, would he dare to give them bad things?

How could it be broken in just these few days?

While worrying about his father's health, Liu Tan began to wonder if something went wrong.

After thinking about it carefully, he took someone to take the accessories that might be used. The water inlet and outlet of the water tank, and other places can be replaced. Liu Tan now wonders if those people don’t understand, so they made a wrong judgment. place.

After Liu Tan entered the palace, he didn't see Liu Che for the first time. At this time, Liu Che was still discussing politics, and he didn't even see Liu Shi.

But fortunately, there was no need to make him wait, the little yellow gate directly took him to a side hall.

Liu Tan didn't have any doubts when he saw that the toilet was placed in the side hall. After all, the toilet was broken, so why should the emperor use the broken toilet?Of course, it needs to be moved to the side hall to wait for repairs, and then changed back.

But when he got there, he saw a brand new toilet on a clip in the center of the side hall.

When Liu Tan first saw the toilet, he thought it had never been used. After all, it looked so new.

But think about it, the things used by the emperor are of course cleaned every day to ensure that the things are always bright as new.

He first asked people to see where the broken parts of the water tank were and how they were broken.

After all, even if he is the founder of the toilet, there is no reason for the majestic king of the North to repair the toilet himself, even if it is the emperor's toilet.

Liu Tan stood aside and asked implicitly, "Has this toilet been used a lot lately?"

In fact, he really wanted to ask if his father was in poor health.

But if this kind of problem is put in ordinary people, it is the son who cares about Lao Tzu, but it is easy to misunderstand when it is put in their house-what do you want to ask about the emperor's physical condition?

Liu Tan didn't dare to ask directly, so he could only go around in this way. The detour was not to prevent Liu Che from finding out, but to tell Liu Che that he had no other intentions.

Xiao Huangmen nodded and said: "It is true that it has been used a lot, but His Majesty thinks that the Shangguan Taifu pressed too hard and caused damage."

Liu Tan sounded a little strange: "Shangguan's servant? This...what does this have to do with Shangguan's servant? This toilet...is Shangguan's servant also used?"

What Shangguan's eunuch was talking about should be Shangguan Jie. He should be regarded as one of Liu Che's most important ministers now, but no matter how important he is, Liu Che would not share the toilet with others!

Xiao Huangmen said: "Yes."

Liu Tan couldn't help gasping: "No, tell me in detail. If His Majesty asks, you can say that the toilet is exquisitely constructed, and I need to know more before I can fix it."

This matter was really subversive. He knew that the emperor of the Tang Dynasty liked to meet in the bathhouse, but that was when the emperor took a bath and other people watched and chatted with the emperor.

Liu Che shared the toilet with someone?Is it because he didn't wake up?

Xiao Huangmen knew everything, and said directly: "A few days ago, Shangguan's eunuch and Da Sinong came to visit. Your Majesty first let us show it, and then the eunuch and Da Sinong were curious, so they personally I tried it with my hands, but it broke."

Liu Tan's expression was dull: "Shangguan's eunuch and Da Sinong... came to visit...the toilet together?"

What kind of hobby is this?The current Da Si Nong is Sang Hongyang, these two can't beat Liu Che's horses to this extent, can they?

No, really flattering doesn't mean using Liu Che's toilet.

Liu Tan felt that there must be something he misunderstood, so he asked again: "Aside from Shangguan Taifu and Da Sinong, who else has visited this toilet?"

Xiao Huangmen announced a series of names, good guy, he even heard the names of Princess Yangxin and Princess Dangli!

Liu Tan only felt dizzy for a while. At this time, no matter how stupid he was, he knew that Liu Che must have never used it, but he took this thing as a novelty to share with everyone!

As for what?

Liu Tan didn't understand. He offered so many things. Liu Che had never done this before. What's so special about the toilet?

He felt that he needed to communicate with his father, this toilet is not for visiting!

Not long after, the craftsman brought by Liu Tan came down and said, "Your Highness, it has been replaced."

Liu Tan asked, "Can you see how it's broken?"

The craftsman hesitated a little, Liu Tan waved his hand and said, "If you tell me what you want to say, then you can go back first."

After hearing this, the craftsman breathed a sigh of relief and said, "It's the damage caused by frequent pressing."

Liu Tanxin said that Liu Che asked so many people to visit, and everyone pressed it several times, so it is not easy to damage it?

After the craftsman finished speaking, Liu Tan really asked him to go back first, then turned around and ran to wait for Liu Che to finish discussing the affairs of state.

When Liu Che heard that Liu Tan was entering the palace after the political discussion, he immediately summoned him.

When meeting Liu Tan, Liu Che was very surprised, because he rarely saw such a serious expression on his son's face.

Liu Che watched him sit down sternly and couldn't help laughing: "What's the matter today? Who made our Northern King angry?"

Liu Tan looked at him seriously and said, "Father, the things I gave you are all for your use, why are you still using them for exhibition?"

Um?exhibition?

Liu Che soon understood a little bit, and said with a smile: "It's just that everyone is a little curious."

Liu Tan's eyes widened: "If they are curious, let them go to Erchen. How can they damage your things?"

Liu Che is not so stingy, of course, it should be because he is sure that Liu Tan can fix it even if it is broken.

Seeing what Liu Tan said at this time, he stamped a big seal on a document and said: "Is it possible that they can ask about fairy arts casually? Just show them, and don't let them bother you. "

"Ah?" Liu Tan was at a loss: "Where did you get the fairy art?"

Before Liu Che could say anything this time, Liu Tan asked in shock, "You... you are talking about the process of flushing the toilet, right?"

Before Liu Che said anything, Liu Tan knew that he had guessed right. For a moment, Liu Tan was very desperate. If you don't understand, just say it, pointing to science and talking about theology, can you still get better!
