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

Liu Tan had no choice but to honestly deliver the things he brought.

Both Liu Che and Liu Ju were a little dumbfounded—this...it looks good, pretty, and it seems really convenient, but...the direction of your research is not right?

Liu Che couldn't sit still and said, "You... just study some beautiful equipment, don't mess with these..."

Liu Che couldn't go on talking. Although excretion is one of the most important things in life, you should pay attention to your image anyway.

It was said before that the King of the Northern Realm likes to play with mud. It was too much. Fortunately, Qianfeng Cuise was finally created. Now everyone is very fond of Qianfeng Cuise. Playing in mud is not a very classy thing.

But now they are starting to toss the toilet again, this... Does it spread that the old Liu family doesn't want to lose face?

Facing his father and elder brother who were nearly identical in their words, Liu Tan shrank his neck and said, "No, no, it's not Erchen, it's... yes... it was researched by Erchen's craftsmen, and Erchen improved it a little when he saw it was good. for a moment."

The reputation of researching toilets is really not good. In fact, Liu Tan didn't intend to take the credit for himself at the beginning. Anyway, no one went back to ask which craftsman under him did the research.

It's just that after he said that, both Liu Che and Liu Ju looked in disbelief.

When they are stupid?This thing seemed to appear out of thin air, and it had nothing to do with the toilet in the past. They wouldn't believe it wasn't Liu Tan's handwriting!

But this is also an explanation, at least to cover up the past.

Liu Che even wondered if it was because Liu Tan couldn't take it anymore. After all, it has been a little over a year since he returned to the palace, and the cost of food and clothing is the highest in the world, but it seems that it is still far behind the toilet. Talk about getting used to it for a year and can't get used to it, so start improving?

Thinking of this, Liu Che seemed to understand a little bit again.

He hesitated for a moment, every time Liu Tan made something strange, he was also very curious about the so-called new type of toilet, but the emperor seemed a little out of place around the toilet.

Liu Ju knew his father better than Liu Tan, and turned his head to wink at Liu Tan.

Liu Tan was still a little dazed at the beginning, but soon he also realized, oh, Liu Che should be embarrassed to say that he wants to see it, so he simply said: "Come here, bring the things up."

When the siphon toilet was brought up, it basically overturned Liu Che and Liu Ju's perception of the toilet.

Among other things, just look at this clean shape, Liu Tan even made a sun-engraved pattern on the toilet, and people will believe that it is a treasure!

After the toilet lid was opened, although the inside was different from an ordinary toilet, it was actually not much different. What made the two even more curious was the thing standing behind the toilet.

Liu Tan had known for a long time that he would demonstrate on the spot, so he asked someone to bring a basin and water, and opened the lid of the water tank by the way, so that Liu Che and Liu Ju could see the results clearly.

Liu Ju looked down for a while and asked curiously, "What are these pipes for?"

Liu Tan said: "Into the water, you can enter the water when you connect here."

Liu Ju was a little puzzled: "How does this get in the water?"

Is it too laborious to pour water through such a small hole?

Liu Tan rubbed his nose and said, "This is reserved in advance, and there is nothing that can automatically enter the water yet..."

Liu Che grasped the important point in time: "Automatic water intake?"

Liu Tan responded: "Well, if it can automatically enter the water, it will be useful. It's not very useful now, but I made it out in advance."

Liu Che nodded, and drew a key point in his mind: the water in the fairyland flows in automatically.

Liu Ju asked again: "What about the ball? Why is there such a thing?"

Liu Tan said: "It is to close the water inlet. The capacity of the water tank is limited, but if it cannot be closed, the automatic water intake will be endless, and the water will overflow."

Seeing that Liu Tan was struggling to explain, he simply asked someone to take a bamboo pipe and connect it to the water inlet of the toilet, and then began to fill it with water. At the same time, he pointed to the closing plug and said, "Pay attention here."

As the water level inside the tank rises, the levitating ball begins to float. After reaching the set position, the water plug that was lifted up directly blocks the water inlet. Even if you continue to add water, it will no longer fill the toilet. It was left in the bamboo tube.

Liu Che saw it strangely and asked, "How is this controlled?"

Liu Tan simply asked someone to take a brush, tied a gold ball and a few copper coins at the same time, and then put his hand in the middle of the brush and explained: "For example, this gold ball is this ball. Of course the ball is lighter than it, so there is When the water is suspended, it is the same as the current state of full water, so that the plug will be plugged into the water port, but when the water level drops."

Liu Tan let go of the hand that was holding the golden pill while talking. The golden pill fell and the copper coin went up in an instant. He said, "Then the water plug will be pulled up, and the water will continue to enter the water inlet."

In fact, Liu Tan is not sure whether there is any specific application of buoyancy these days, but thinking about the wisdom of the ancient people, he thinks it should not be useless, but a scientific system has not been formed, so as emperors and princes, there is no need to know These things, because they are used in places where they are considered cheap slaves.

This metaphor is vivid and simple, but it made Liu Che feel a little interesting, and then asked: "Then what's next?"

Next, the next step is to test the flushing ability.

Liu Tan asked people to put small wooden balls in the toilet. Originally, later generations liked to use plastic balls in those tests, but he doesn't have one now, so naturally he can only use this instead.

He asked people to put the toilet lid up, reached out and pressed the button, and in an instant, water poured down from the inner edge of the toilet, forming a huge vortex to wash down the wooden balls, and all the wooden balls entered the basin below to catch the water.

Liu Tan said, "Look, that's it."

As soon as he turned his head, he saw Liu Che and Liu Ju staring at him in a daze. The smile on Liu Tan's face gradually disappeared, and he couldn't help asking in a low voice, "What's wrong?"

Is this not fun?

But if Liu Che and Liu Shi didn't like it very much, there was no need to force them to change the toilet.

The market for this kind of toilet is actually in the middle class, that is, people who have a little money and want to improve their quality of life, but they cannot afford so many slaves at home.

After all, Dao Yexiang also needs people, but in this way, the sewage drainage system of Chang'an City can be fully used. If it is really not needed, it is easier to build a special place at home and use it as fertilizer.

It's just that he probably didn't expect that when Liu Che and Liu Ju saw the water in the toilet suddenly forming a vortex with a huge momentum, there was only one thought in their minds: Has this thing been cast with a magic spell?
