For Bi Maokang's compliment, since Zhu Youjian arrived in the Ming Dynasty, his ears are calloused, but every time he hears it, he is still a little proud.

It doesn't feel too good to change the fate of others and save thousands of lives with your own strength.

"The minister thinks that His Majesty's virtue is glorious through the ages, and the minister dares to ask His Majesty to give this furnace as 'Chongzhen Furnace', so that everyone in the world can feel the emperor's grace."

Bi Maokang said sincerely, Zhu Youzhen was almost moved by him, but after thinking about it, forget it.

If this furnace is called Chongzhen Furnace, then whether the briquettes should be called Chongzhen Balls, Chongzhen Briquettes, it is too low-grade, and I am originally plagiarizing the creativity of unknown people in later generations, so it is better to keep a low profile. ’

Thinking of this, Zhu Youzhen said forcefully.

"It's just a trivial matter, how can I be a person with such a false name, this thing looks like a honeycomb, it is called a honeycomb briquette and a honeycomb coal stove, and the people will understand it as soon as they hear it."

For Zhu Youzhen's attitude of not loving fame and serving the people wholeheartedly, Bi Maokang admires it even more.

The two continued to walk forward, and were about to walk to the door of the machinery factory, when Bi Maokang suddenly stepped forward and said.

"Your Majesty, I think it would be better if you left a little door and window open when burning charcoal, so that the poisonous smoke could escape a little."

When Zhu Youzhen heard this, he almost tripped over the threshold.

Isn't it common sense to burn charcoal and smoke when you open the window, just think about it for so long, Zhu Youzhen not only thinks that Bi Maokang is not a good brain.

But in fact, this is Zhu Youjian on the basis of the rapid development of natural science in later generations to see the predecessors, the Ming Dynasty people do not know that smoke is toxic or harmful, and it is cold in winter, it is too late to close the doors and windows to keep warm, who will be hot to open the window to disperse smoke.

Besides, some smoke in the house can still be warmer, and the ancients also had a hobby of burning incense, and they couldn't accept the smoke or anything like it as the people of later generations.

However, Zhu Youzhen's cultivation is not bad, even if he thinks that Bi Maokang's brain circuit is a little unbelievable, and he still has to support this idea, because Bi Maokang, a smart person in the Ming Dynasty, is like this, and the ignorant ordinary people don't know it.

"Yes, yes, if you can ventilate well, you won't be poisoned."

Bi Maokang nodded yes, and followed Zhu Youzhen into the machinery factory.

Because of the freezing in winter, the hydraulic forging hammer is no longer usable, so the drilling machine and forging machine that are still working are all animal power.

Compared with stable hydropower, the output power of animal power is somewhat inconsistent, and the efficiency is also lower.

But in general, it's much better than manpower.

"It is still necessary to pay close attention to the development of steam engines, which is the foundation of power, and with steam engines, these factories do not have to be built by rivers."

Since last year, because of the development of the steam engine, two craftsmen have been injured, one of whom was injured because the fragments of the boiler explosion hit the lungs, and the injury was quite serious, so he did not survive.

For the injured and the dead, Zhu Youzhen gave a lot of pensions, so this incident did not cause bad public opinion in Xishan.

Bi Maokang hurried to Nuo's should be.

"You must pay attention to safety, don't have any more accidents, by the way, how did you study the thermometer and pressure gauge I said?"

Temperature and pressure are important indicators to control the safety of boilers, so after the successful development of glass, Zhu Youjian asked to speed up the manufacturing.

"Back to Your Majesty, it's still developing, it's still developing."

Bi Maokang wiped the sweat from his head and said a little nervously.

Zhu Youzhen heard this, and didn't say anything more, the glass products just came out, and the principle of temperature and pressure has not yet been understood, so it is indeed difficult for some strong people to want thermometers and pressure gauges.

After thinking about it, Zhu Youzhen said again.

"Before the thermometer and pressure gauge come out, this boiler should not be experimented, but the piston connecting rod drive device must be developed as soon as possible, and when the boiler can be stably controlled, it can be used directly."

Without industrial pressure gauges and thermometers, the boiler is a time bomb, and if you want to rely on the experience of craftsmen to control the boiler from exploding, that is not the industrialized large-scale production model that Zhu Youzhen wants.

When Bi Maokang heard this, he immediately breathed a sigh of relief, as long as he didn't play with the boiler, the piston connecting rod or something would be much safer.

"The road to the steam engine has a long way to go, but if it happens, it will be a big thing that will change the world, no matter who overcomes the difficulties, I will not be stingy with the knighthood."

When Bi Maokang heard this, he was stunned.

Zhu Youzhen has said many times about the importance of the steam engine, but because he has not seen the real thing, Bi Maokang has not realized how useful it is, but because the Son of Heaven attaches great importance to it, he has been intensively developing it.

It wasn't until today that the Son of Heaven wanted to say knighthood, and Bi Maokang didn't know that it was really important.

Since the ancestor, the martial arts of the Ming Dynasty are not highlighted, except for relatives, the imperial court has rarely been knighted, and the Son of Heaven took out the title at this time to reward the developer of the steam engine, and the importance of the steam engine is self-evident.

Not only Bi Maokang, but also the generalissimo's officials and workers who were working in the factory who accompanied the inspection were stunned when they heard this.

Knighted for merit, that is a title that shelters the descendants and lives with the country, and it is not exchanged for a prime minister.

You don't see that the Ming Dynasty has been founded for more than 200 years, and there are hundreds of cabinet auxiliary ministers, but few families have been prosperous for a hundred years, but the princes and earls after the founding of the Ming Dynasty and the Jingjing disaster can do it.

Except for the bigwigs involved in various true or false rebellion cases in the early Ming Dynasty, most of the nobles with titles have been handed down.

Like the Xu family of Yingtianfu, the Zhang family of Shuntianfu, and the Mu family of Yunnan, these titles have been passed down for more than 200 years, and they are truly the same as the country.

Since ancient times, wealth has moved people's hearts, and with this title hanging in front, Zhu Youzhen believes that the first steam engine of the Ming Dynasty will not let him wait too long.

Out of the machinery factory, Zhu Youzhen went to the glass factory again, and now there is palm-sized glass production, although some still have some bubbles, but compared with the glass products from the West, the condition is much better.

According to Bi Maokang, if it is taken out and sold, it will definitely make those counterfeiters in the West lose their place.

Regarding Bi Maokang's statement, Zhu Youzhen smiled and did not speak.

During this period, Western Glass and Zhu Youjian Xishan Glass Factory were not the same road at all, nor were they a set of production processes.

At this time, because the Western craftsmen did not know the principle of glass production, according to the difference in the skills of the craftsmen, the carrier of glass was mostly hand-produced handicrafts, and most of them were colored, and it depended on luck to produce a flat completely transparent glass.

However, because of Zhu Youzhen's golden finger, Xishan's glass factory has known the production principle of glass from the beginning of its establishment, so even if there are some bubble defects, the glass produced is basically flat transparent glass.
