On the edge of the Yuhe River (Tonghui River) in the southeast corner of the inner city of Jingshi, experts from the Academy of Engineering such as Tianqi, Xu Guangqi, Wang Zheng, and Song Yingxing carefully watched a running hydraulic machinery on the river.

With the flow of the river, the arm on the machine is driven forward, and then under the action of the transmission structure composed of gears and racks, five side-by-side drill bits move forward at the same time.

And directly in front of each drill bit, a long round tube is fixed.

The drill bit is inserted from the middle of the round tube and stirred wildly.

Since the drill bit and the pipe were submerged in the water, there was no harsh noise, and a cloud of black water flowed out of the pipe and scattered with the river.

After looking at it for a while, Apocalypse nodded secretly, quite satisfied with his craft.

It is not difficult to see that this is a set of hydraulic drilling machines, and the main purpose is naturally to drill the barrel.

In the past, it was mainly manpower to drill the barrel, and it took about a month for a skilled craftsman to drill a barrel, and the efficiency was very slow.

And now this set of drill pipe machinery can drill five barrels at the same time at one time. If you make a larger one, it's not impossible to drill ten at a time.

Although I don't know how long it will take to drill well, it will definitely not take as long as a month, and the efficiency will be greatly improved and it will be more labor-saving.

Wang Zheng, who was not far away, looked straight in his eyes, he didn't expect Banzai to be able to create such an exquisite hydraulic machine, and he couldn't help but feel a little embarrassed.

Long live every day, creating a machine at will, and making yourself out of reach, then your research in the past few decades is really too much to do.

But he didn't know that his long live came with a plug-in, and he didn't know that he used his brain, as long as there was an invention point, this kind of machine could not be invented casually?

And in terms of structure, compared with those precision machines in later generations, it is so simple, just follow the drawings.

Although Song Yingxing was also shocked, he was more absorbing knowledge and preparing to include it in a book he was conceiving.

Moreover, among the many experts of the Academy of Engineering, he has the lowest qualifications and influence, and has always been with a learning mentality.

When Jin Yiwei found him at that time, he was very confused, and he really couldn't figure out how he could attract the attention of Banzai if he failed to pass the test several times in a row, and he didn't achieve anything.

even sent a lot of Jinyi guards to find the Beijing division from Jiangxi, and then found Jiangxi from the Beijing division, which is really unimaginable.

Even after meeting Banzai, he still didn't figure it out and didn't dare to ask, so this puzzle has been hidden deep in his heart and cannot be solved.

But for the newly established engineering academy, Song Yingxing is very happy to be able to come in, because he is very interested in these scientific research.

It is really a dream to be able to discuss and learn the academic knowledge of agriculture, handicrafts, machinery, smelting, weapons, gunpowder and other academic knowledge of the Ming Dynasty with adults such as Xu, Wang, Bi, and Sun, which I never dared to think of before.

Moreover, the Academy of Engineering is a yamen founded by Banzai, which has official positions and grades, and works as an engineer and serves the Ming Dynasty.

It can be said that the regret of trying a few times has been made up for in the Academy of Engineering, and there is no officialdom here, and everyone is concentrating on research together, so these days are the most comfortable time in his life, and he cherishes it very much.

"A few Qing families, you can pay more attention to whether there are other improvements to this set of machinery, you can try boldly."

"If it's not a big problem, I'll build more."

"Yes, hooray." Xu Guangqi and others hurriedly responded to the order, and they were also very emotional in their hearts, most of the achievements of their engineering institute were actually from the hands of Banzai.

Whether it is a flintlock pistol, as well as the machinery that grinds gunpowder before, plus the current set of drill pipe machinery, it is of great significance.

Although they didn't say anything, the experts of these engineering institutes have silently made up their minds in their hearts to redouble their efforts in the future.

Otherwise, if you don't get enough results, even if you don't say it, your own people will have no shame, and you won't be able to face the criticism of others.

When Xu Guangqi and others had their own thoughts, Tianqi also found a problem, these machines are different from flintlock pistols, even if they are mass-produced, the number is very limited, so it is more difficult for them to get more invention points.

And now, as the process of producing flintlock pistols becomes more and more mature and efficient, the rate of invention points exchanged is slowly decreasing, and it is becoming more and more difficult to earn invention points at that time.

Therefore, it is necessary to find other ways to obtain the invention point as soon as possible.

The most effective way is to invent or improve several products, which require not many inventions, but can be mass-produced.

Apocalypse immediately thought of farm tools and textile tools, which were used by almost every household, and as long as the people could afford them, the scale of this mass production would be very large.

With this matter in mind, Apocalypse was ready to accumulate enough invention points and then start inventing.

Soon after returning to the palace, news came from Jinyiwei that Lin Dan Khan had finally pacified the Mongolian right wing.

However, this also had a consequence, and some tribes who did not want to submit to him left the right flank and chose to surrender to Houjin or defect to Mobei Mongolia.

And Lin Dan Khan's move will naturally attract more Mongolian tribes to be dissatisfied and resentful of him, so that they will be even more detached.

Tianqi also knew that cooperating with such Lin Dan Khan was actually on the opposite side of other Mongolian tribes, but he had known this result and did not regret it.

Because he knew very well that even if he didn't offend those Mongolian tribes, they would not stand on the side of the Ming Dynasty to fight against the Houjin, and it was more likely that they would take refuge in the Houjin to deal with the Ming.

In that case, why not unite with the Chahar Ministry, which has the deepest grudge against the Houjin?

Now that Lin Dan Khan's Chahar Department has completely occupied the Mongolian right flank, there should be no large-scale military operations for the time being, which cannot allow him to be idle and can carry out the next plan.

"Fight the Mongol traitors who surrendered to Jianguo, and cut off the tentacles of Jianguo reaching into Mongolia......"

With this guideline, Apocalypse sent a delegation to the Mongol right flank to negotiate with Lin Dan Khan.

The meaning of the apocalypse is very simple, since both of us are inferior to Jianguo in the field battle, then we will first find a way to cut off their minions, such as those Mongol tribes that surrendered to Jianqing, and deal with them one by one from near and far.

These Mongol tribes, even if they don't want to be on our side, can't let them become vassals of Jianguo against us.

Lin Dan Khan was a little shocked when he learned of the idea of the Apocalypse, not because he didn't want to deal with these Mongol traitors, but because he was worried about attracting revenge from Jian.

After all, it's too late to hide, so why take the initiative to provoke them like this? Isn't this forcing Jianyu to send troops?
