Of course Wang Buxu was not too lazy and overslept.

But...

Last night, he was woken up by the cold...

That's right, I woke up from the cold...

I don’t like to wear too many clothes when sleeping, as this will make me feel uncomfortable.

I don’t want to cover myself layer by layer, as so many layers would feel too heavy on my body.

Cotton has been made into clothes and sent to the front line. As an emperor, you still have to take care of it. You can't cover it with your own cotton clothes when you sleep, right?

So the king woke up before dawn and was not hungry.

He called Wang Ji over angrily, and held Wang Ji together for a heated discussion.

The charcoal basin is really good, but ventilation is a flaw.

While taking away carbon dioxide, it also takes away a lot of heat.

"Why are you so stupid? Why don't you understand my intention?" Wang Buxian looked at Wang Ji angrily.

Damn it, is it that difficult for you to make a heater?

I didn’t ask you to heat the entire Luoyang, nor did I ask you to heat the entire palace.

It’s just asking you to assemble a small heating device. Why is it so difficult?

"Your Majesty, when..." Zhang Buyi was a little anxious.

"Stop talking yet!" Wang Buxuan interrupted Zhang Buyi's interruption.

"Your Majesty, the main reason is that the water flows downwards. You said this, the water may flow from both sides at the same time. Then it will not be able to circulate, and the hot water will not be able to pass..." Wang Ji scratched his head in pain.

Looking at the picture drawn by Wang Buxu, the principle is very simple.

You can think of it as drilling two holes on both sides of a pot, then using a pipe to go out and twist it around, and then connect it back through the other end.

This principle is really not difficult. What is difficult is how to let the water pass through from one side and come back from the other side.

If water wants to run through a pipe, to put it simply, it must have enough power, otherwise it will not flow even if it goes in.

Wang Buxu wished he could scratch his scalp. Of course he knew the principle, but he couldn't help himself because he didn't know how to do it.

So, this is a big problem.

If it were in the future, what kind of problem would this be?

It only costs a few hundred dollars to buy a pressure pump, and the internal pipelines can be routed as they please without any consideration.

But now.

There is nothing you want, nothing you can do.

As for the choice of pipes, cast iron is naturally the best, but its corrosion resistance will be worse.

Copper has relatively strong heat dissipation, so it is also suitable for making pipes. But now that there is a shortage of copper, I wish I could use it to mint coins. Who would be luxurious enough to use it to make pipes?

After much thought, Wang Buxian came up with a good idea.

First, he took out a pen and drew a circle on the side of the bottom, and said: "This is the water outlet, and opposite the top is the water return outlet. Leave a hole at the top. It is usually used to add water and so on. Just close the lid when not in use!"

"Your Majesty, you are just letting the water flow to higher places. This is absolutely not possible." Wang Ji objected immediately.

"Just do it, make a smaller one to try first!" Wang Buxian was already a little impatient.

Although it is true that the water flows to higher places, there is one thing that Wang Buxin cannot tell Wang Ji.

After covering the upper lid, this is a relatively sealed environment. When the bottom is heated, the internal pressure will change with the temperature change.

Even if the temperature factor is not considered, even if there is so much water pressing on it, the pressure is enough to drive the water away.

How far you can go and how fast you can go depends on the length and angle.

In other words, this is just a simple version of a boiler, right?

Although he is not playing with steam.

Sure enough, many things in this world were invented by accident. For example, so-and-so discovered penicillin by accident, and so-and-so discovered popsicles because of an accidental mistake.

Another example is Liu An, the king of Huainan in history. He invented tofu because he felt that life was too boring and the food he ate was too simple.

Wang Buxu suddenly discovered that the Chinese people's invention skills seemed to be all wrong...

Historically, Liu An invented tofu and accidentally discovered gunpowder while refining alchemy. Even if he discovered gunpowder, he knew that people would die after the explosion. However, the big guys used gunpowder to make fireworks. It seemed that they never thought about becoming

Military weapons?

Now I was woken up by the cold at night and accidentally invented the world's first man-made boiler?

It's better to get gunpowder too. Anyway, this thing is not difficult. Although I don't know the specific ratio, the formula is just those three things. Let people test it slowly, and there will always be a suitable one.

As for the power of black powder?

Is the issue of power a problem for today's big men?

First of all, I don't need to attack some steel fortress with these things.

Then, I don't need it to turn this world upside down.

In the end, all I need is something that can play a role in defense.

No matter how weak the power is, it is still an explosive. I use ceramics as the carrier. When it explodes, the fragments produced can still hurt horses or people.

For me, just these are enough.

When defending, with these things, one person can be used as two people.

When fighting in the wild, lay a mine array directly outside. When your cavalry comes over, this wave will disrupt your rhythm and scare your horse into convulsions and uncontrollable attacks.

Especially during a sneak attack, if you throw a few of them over and make a bigger noise, what else are you going to do next?

Well, we have a head start, so we have to put this on the schedule as soon as possible. Try to get it out this winter, and then take a group there in the spring of next year to go to the Western Regions and let those people experience the power of the big man.

"By the way, when is it?" Wang Buxian suddenly felt that something was not right, as if he had forgotten something today.

"It's almost the second quarter of the morning..."

"Why didn't you remind me?" Wang Buxian suddenly felt that he was playing too big.

It's the second quarter of the morning, which is half past eight.

In later generations, this was the time when I had just started working, and everyone was still sleepwalking.

But now, this is a point in time when it has entered working mode.

When holding a court meeting, ministers need to enter the hall before Chenchu, that is, before seven o'clock.

The court meeting will begin at the beginning of the Chen period. Depending on the amount of business, the court meeting will usually end before the end of the Chen period, unless there are too many things.

But that's impossible. Throughout the ages, there have always been small meetings on big things and big things on small things. The bigger the meeting, the more it goes through a process and it's done.

Seeing that the court meeting was almost over, Wang Buxuan was momentarily confused.

She couldn't help but feel in her heart that Zhang Buyi was so ignorant that he didn't even remind him about such a big event like the court meeting.

"Your Majesty, you told me to shut up..." Zhang Buyi's face was full of grievances.

"..." Wang Buxian seemed to have remembered this incident, and he seemed to have indeed said this.

"It's my fault, Your Majesty, it's all my fault. If I had spoken faster, Your Majesty wouldn't have missed it..." Zhang Buyi, who had quick eyesight and quick hands, quickly took the blame on himself.

The reason for the grievance was to let Wang Buxian know that he had not forgotten and reminded him, but you were too focused.

Taking the blame now is to give you a step down and let you remember that I am not a tiger.

Otherwise, you, an emperor, would just laugh and say I forgot?

What a slap in the face!

Look now, although he has taken the blame, the emperor knows what the blame is.
Chapter completed!
