Liu Tan had no choice but to honestly hand over the things he brought.
Both Liu Che and Liu Ju were a little dumbfounded - this... thing looks good, it looks nice, and it seems to be really convenient, but... isn't your research direction right?
Liu Che couldn't sit still and said, "You...just study some beautiful instruments, don't do these..."
Liu Che was at a loss for words. Although excretion is one of the most important things in life, you should at least pay attention to your image.
It was already too much to say that the King of the North liked to play in the mud. Fortunately, Thousand Peaks Emerald was finally created. Now everyone is very fond of Thousand Peaks Emerald, and this thing seems to be high-end, which barely covers up the fact that Liu Tan played in the mud, which was not very classy.
But now they’re messing with the toilet again. If this gets out, won’t the Liu family have any face?
Facing his father and brother's almost identical indescribable words, Liu Tan shrank his neck and said, "No, no, no, it wasn't you, your son. It was... it was... it was your son's craftsmen who figured it out. I thought it was good, so I improved it a little bit."
It would indeed be bad to have the reputation of researching toilets spread. In fact, Liu Tan did not intend to take the credit for himself at the beginning. Anyway, no one went back to ask which craftsman under his command had done the research.
But after he said this, Liu Che and Liu Ju both looked disbelieving.
Do they think they are stupid? This thing seems to have appeared out of thin air, and has nothing to do with the toilets of the past. They don't believe it's not Liu Tan's work!
But this is also an explanation, at least it covers up the past.
Liu Che even wondered if Liu Tan finally couldn't stand it anymore. After all, more than a year had passed since he returned to the palace. His food, clothing, and daily necessities were all top-notch in the world, but it still seemed far inferior to a toilet. Liu Tan couldn't get used to it after a year, so he started to improve it?
Thinking of this, Liu Che seemed to understand a little bit.
He was a little hesitant for a moment. Every time Liu Tan made something new, he was very curious about the so-called new toilet. But it seemed a little inappropriate for the emperor to look around the toilet.
Liu Ju knew his father better than Liu Tan did, so he turned around and winked at Liu Tan.
Liu Tan was a little confused at first, but soon he realized that Liu Che was too embarrassed to ask for a look, so he simply said, "Come here, bring the things up."
When the siphon toilet was introduced, it basically overturned Liu Che and Liu Ju's understanding of toilets.
Putting aside other things, just look at the smooth appearance. Liu Tan even specially made a relief pattern on the toilet. People would believe it if he said it was a collectible!
After the toilet lid was opened, although the inside was different from an ordinary toilet, there was actually not much difference. What made the two of them even more curious was the thing standing upright behind the toilet.
Liu Tan already knew that he would have to demonstrate it on the spot, so he asked someone to bring a basin and water, and at the same time opened the lid of the water tank so that Liu Che and Liu Ju could see the results inside.
Liu Ju lowered his head slightly and looked for a while before asking curiously, "What are these tubes used for?"
Liu Tan said: "Water can be brought in by connecting it here."
Liu Ju was a little confused: "How can water get into this?"
Isn't it too much effort to pour water into such a small hole?
Liu Tan touched his nose and said, "This is reserved in advance. We haven't developed something that can automatically fill with water yet..."
Liu Che grasped the key point in time: "Automatic water inlet?"
Liu Tan responded: "Well, if it can automatically fill with water, this will be useful. It's not very useful now, I just figured it out in advance."
Liu Che nodded and made a point in his mind: the water in the fairyland flows in automatically.
Liu Ju asked again: "What about this ball? Why is there such a thing?"
Liu Tan said, "It's to close the water inlet. The capacity of the water tank is limited, but if it can't be closed, the water will flow in endlessly, and the water will overflow."
Seeing that explanations were tedious, Liu Tan simply had someone bring a bamboo tube to connect to the toilet's water inlet, and then began to pour water into it, pointing to the shut-off plug and saying, "Pay attention here."
As the water level inside the water tank rises, the suspended ball begins to float. When it reaches the set position, the water plug that was originally raised directly blocks the water inlet. Now, even if you continue to add water, it will no longer flow into the toilet, but will remain in the bamboo tube.
Liu Che looked at it curiously and asked, "How is this controlled?"
Liu Tan simply had someone take a brush and tie a gold ball and several copper coins to one side. He then placed his hand in the middle of the brush and explained, "For example, this gold ball is the ball. Of course, the ball is lighter than it, so when there is water, it floats above it, just like when it is full of water now. This way, the plug will be pushed into the water outlet, but when the water level drops."
As Liu Tan spoke, he released his hand that was holding the golden ball. In an instant, the golden ball fell and the copper coin rose. He continued, "This will pull up the water plug, and then the water inlet will continue to flow in."
In fact, Liu Tan was not sure whether there was any specific application of buoyancy these days. However, when he thought about the wisdom of the ancient people, he felt that it was not useless, but it had not formed a scientific system. Therefore, as the emperor and the prince, they did not need to know these things, because any use of these things would be considered menial work.
This metaphor was vivid and simple, which made Liu Che feel quite interesting. He then asked, "What's next?"
Next, the next step is to test the flushing ability.
Liu Tan asked someone to put a small wooden ball in the toilet. Originally, those tests in later generations liked to use plastic balls, but he didn't have any now, so naturally he had to use this instead.
He asked someone to put the toilet lid on, reached out and pressed the button, and instantly water poured down from the inner edge of the toilet, forming a huge vortex that washed the wooden balls down, and all the wooden balls fell into the basin below to collect water.
Liu Tan said, "See, that's it."
He turned around and saw Liu Che and Liu Ju staring at him in amazement. The smile on Liu Tan's face slowly disappeared, and he couldn't help but whispered, "What's wrong?"
Don't you think this is fun?
However, if Liu Che and Liu Ju didn't like it, there was no need to force them to change the toilet.
The market for this type of toilet is actually the middle class, that is, people who have a little money and want to improve their quality of life but cannot afford to keep so many slaves at home.
After all, it takes people to remove the night-blooming incense, but this way we can make full use of Chang'an City's sewage discharge system. If we really can't use it, we can set up a special place at home, and it will be easier to use it as fertilizer.
But he probably couldn't have imagined that when Liu Che and Liu Ju saw the water in the toilet suddenly form a vortex with huge force, they had only one thought in their minds: Was this thing cast under magic?
