Li Shimin watched it quite well at first, this pendulum clock Li Ke told him before, but Li Shimin's expression was not right, especially the quibbly remarks, Li Shimin was amazed.

Good guys, so that you can quibble about the past? I knew I was quibbling like this before.

But thinking about it, it doesn't seem right, he used to be a diligent politician, if anyone doesn't let him go to the court and doesn't let him deal with state affairs, Li Shimin will suspect that the other party has ulterior motives.

I can only say, hey, the age is different, the thoughts are different, and I am older.

After reading it, Li Shimin shook his head and directly handed the things in his hand to Chang Lin: "Go, hand it over to Chu Suiliang, I'm done." ”

"Yes." Chang Lin went out with his things.

Li Ke came out of the palace, but he didn't go to other places, he still has to go to Tanchun Tower tonight, the renovation project of Huiyue Tower is basically coming to an end, and the stage play that should be launched is naturally going to be launched.

This actor and the like are also going to start choosing.

When Li Ke was resting in Chang'an City, in the afternoon, in the eastern industrial zone of Chang'an City, Lu Daqiang and others were quietly looking at a behemoth in front of them. A few master blacksmiths were using the wrenches in their hands to turn a few large screws, and when the last one was screwed, everyone took a deep breath.

"How's it going, guys? Startup? Liu Chang looked at Lu Daqiang and asked.

"Let's get started!" Lu Daqiang was also a little excited, "This is the first thing that our people have taken the initiative to develop after learning so much from His Highness, if it is really successful, we may be able to deserve these benefits given to us by His Highness, although this is actually a hint given to us by His Highness." ”

"Ignition!" Liu Chang immediately gave an order, and a craftsman next to him immediately stuffed the red-hot coal next to him into the opening under the large black device, and a shovel of red-hot coal quickly entered the stove below, and then the small worker next to him immediately pushed the large fan below, and the soft cloth channel made of several layers of dense linen cloth was sent to the bottom of the hearth.

As the blower was activated, a roaring flame immediately erupted in the hearth.

After waiting for a while, a device next to it had not responded, and Lu Daqiang couldn't help but say, "Why hasn't there been a response yet?" ”

"Master Lu, when we tested it before, we had to wait for the water inside to boil, the water should not have boiled yet, for safety, Master Lu, Master Liu, why don't you go outside the observation window next to us?" There are thick concrete walls in the middle, so even if it blows up, it won't be a big problem. Zhou Li, who was in charge of the assembly, said, "We have tested it before, and the power of this thing to explode is still quite large." ”

"In this way, add more carbon, and everyone who can get out will go out." Lu Daqiang thought for a while and said, anyway, the blower responsible for the air blast is also behind a thick iron-reinforced concrete wall, and a small hole is reserved underneath to supply air through the cloth blower channel.

"Yes." Everyone thought about it and went out.

Standing at the reserved observation port, everyone looked at the big black machine inside with some excitement, but as time passed, there seemed to be no movement inside.

"Did we make a mistake?" Lu Daqiang took a deep breath and asked.

"Probably not...... I wondered, is our cast iron device too thick? The one we made before was too explosive, and in the end it burst directly, although it didn't cause much harm, but this time we thickened the main structural parts several times, and it should take a while to heat up such thick iron. Liu Chang thought for a while and asked.

As soon as Liu Chang's words fell, a blacksmith next to him suddenly said loudly: "Look, it's moving!" ”

Everyone instantly looked through the observation window, and the flywheel driven by a curved arm reserved next to the massive cast-iron structure began to rotate slowly.

"Quick! Blower up! Lu Daqiang's eyes lit up.

"Yes, blower the wind!" The other craftsman turned and ran, shouting as he went to the next room.

Soon, the two blower craftsmen in the next room also began to push the blower frantically.

As the flames in the hearth continued to rise, the flywheel next to the cast-iron device began to rotate at a terrifying speed, and when it came to the back, when the several cross arms in the middle of the flywheel almost turned into afterimages, and could not even be seen with the naked eye, the crowd let out a burst of enthusiastic cheers.

"Great! It worked! ”

"It worked! I didn't expect our idea to be right! This force is too powerful! Sure enough, what His Highness said is right, the power brought by Gewu is unparalleled! Lu Daqiang's whole face turned red with excitement.

Because the machine in front of him was developed by him, and his inspiration came from the teacher who taught them in physics class that there are many powerful forces in nature, and one example is the lid of a kettle that is pushed by the power of water vapor when water boils.

If it was Lu Daqiang in the past, he would not have thought of this at all, but since these craftsmen began to study physics and chemistry, their thinking has spread a lot, so when the teacher mentioned this thing, Lu Daqiang had an idea, how powerful is this steam?

His current identity is different from before, and His Royal Highness's unconditional support gives Lu Daqiang enough strength to do experiments.

So he had people build a kettle without a pouring spout, since when boiling water, the lid of the pot can be opened by steam when there is a pouring nozzle that continuously spews steam, so what if there is no pouring spout?

When it was built, the new kettle not only did not have a spout, but the lid was raised upwards and then the lid was wrapped around the protrusion, which he then used three small rivets to link the two together.

In this way, the kettle became sealed, and then Lu Daqiang put it on the fire and began to heat it.

And the final result stunned Lu Daqiang, and finally the entire iron kettle made a sound like the explosion of fireworks, and then the whole lid of the kettle was directly collapsed! Because the material of the lid is made of iron sheets, the iron sheets where the three rivets are connected are torn apart.

This huge power stunned Lu Daqiang at that time, and then he went to Liu Chang and discussed with Liu Chang how to make full use of this power.

Later, because Liu Chang was still in charge of another thing, he often stayed in the blacksmith's foundry workshop, so the two of them stayed there while discussing, and then Lu Daqiang saw the blower.
