In fact, this person is not a complete stranger, his name is Huang Huai'an, and he is the eunuch who designed and built the Jinmingchi Daao.

After arriving in Huangzhou, he was appointed as the supervisor of the carpenter, but this man did not like to show his head by nature, so he handed over the management to his deputy, and he shrank alone in the sawmill by the cheese river to concentrate on research.

What is he studying? Hydraulic tools. Ever since he was able to turn unstable water into a relatively stable power source using a variable gear system, he has been fascinated by the automatic tools that Hong Tao speaks of.

This study lasted for more than two years, and he was a eunuch and had no family anyway, so he simply made his residence next to the sawmill, and spent almost all his time dealing with various parts except eating and sleeping, and turned a deaf ear to the noise of the sawmill and enjoyed himself.

These efforts were really in vain, and the first successful development was the sawmill. It has four huge hacksaw blades side by side, and only three people can operate after starting, and only three people can sawn a large wooden double into five pieces of equal thickness, and the thickness can be adjusted, which greatly saves labor.

With this improved invention alone, Huang Huai'an was directly promoted from a technician to the level of senior engineer, and it was granted by Hong Tao himself. It is said that it is a bit overstepping, after all, such a sawmill with high efficiency does not make much sense to Huangzhou.

But Hong Tao doesn't think so, Huangzhou really doesn't need this kind of machinery that can quickly break through giant trees to obtain flat boards, but it doesn't mean that this kind of machinery is useless. Putting it in the coastal area is a big killer, but any shipyard will break its head and rush to buy it.

It doesn't matter if you don't use it now, you don't have to rush to popularize technology, keep it and improve it slowly, and improve all kinds of defects one by one through continuous practice, maybe it will be useful one day, which is called technical reserves.

Huang Huai'an did not let others gossip more, and soon changed the sawmill to a stone sawer, and also adjusted the speed ratio of the gearbox, and evolved from pure hydraulic power to two models: hydraulic power and animal power.

This improvement is too useful for the people of Huangzhou, especially to catch up with the new construction of Liangzhou City, and the efficiency has increased more than ten times after it.

In the past, all the stone strips were chiseled by a stonemason with a hammer, but now they only need to be placed under the stone sawmill, and several strips can be processed at the same time in half an hour at most, which is smoother than manual chiseling. The cost is nothing more than the power of cattle and horses and a few hacksaw blades that can be sharpened repeatedly, and the cost is almost equal to nothing.

But the inventors of these two kinds of machinery are not well known, even if these two machines are named Huang's sawing table, but most people do not know the existence of Huang Huai'an, and even many workers who work in woodwork do not know what their top boss is called, so there is no sense of existence.

The next work will make him even less existential, because he was appointed by Hong Tao as the leader of the R&D team of the machine tool, and all the subjects developed by this group will not be announced to the public in a short time, and the original boring machine and milling machine installed in the Liangzhou workshop are their R&D results.

"This is a pure engineer! You must write down everything they say, don't be too verbose, and have time for the official to write a book for them! This is Hong Tao's advice to Lian'er, who has always been responsible for recording the invention ideas and various data of the craftsmen.

This inferior eunuch was not good at theoretical research, but he was very talented in turning theory into reality. Later generations often talked about science and technology, but in fact, science and technology are two states. The former is a systematic discipline, and the latter is the ability in practical use.

The ancient Chinese invented a lot of things, basically belonging to the category of technology, but have not developed a scientific system, otherwise where there is something in Europe and the United States, which may also be regarded as a cultural limitation.

Hong Tao plans to help the ancients change this habit, and Lian'er is not only Huang Huai'an's record, but also every technological innovation since Jin Mingchi.

It's not just the invention of the master, as long as it is recognized as a technological innovation, she will come to the door with a small notebook, and will never leave without asking how many times you have peed in bed when you were a child. In view of her identity as Mrs. Lian, no one dared to refuse no matter how detailed the question was.

But this time, Huang Huai'an threw down the work of the R&D team and rushed over from Huangzhou non-stop not for technical problems, he was ordered to give Hong Tao an order and ordered Hong Tao to rush back to Huangzhou City immediately.

Who has such a great ability to command Hong Tao? After Hong Tao received the order, he did set off immediately, and he did not dare to delay for half a moment. There are indeed no such characters in Huangzhou and Ganliang Road, and there are actually few in the imperial court. Except for the emperor, whoever comes to Huangzhou will not be in such a hurry to rush back.

But this person is similar to the emperor in Hong Tao's eyes, if he comes to Huangzhou, it basically means that the currency reform has an eyebrow, so he must run back, and he has to run consciously and voluntarily.

"Pei Zhonggui, it must be good news that you came to Huangzhou at such an old age and crossed mountains and mountains, right?"

After resting for only two hours in Mawei City, he changed horses and continued to return to the backyard of Huangzhou Mansion day and night, and the person he wanted to see was actually Pei Ying. can make Huang Huai'an so obedient as a herald, except for the emperor, there seems to be only him.

"Xiaguan Pei Ying, I have seen Lord Shuaisi. Adults are tired from the journey, so it is better to wash up and eat first, and not be in a hurry. ”

Hong Tao returned to Huangzhou so quickly, which surprised Pei Ying a little, but when he saw a colt with a face covered with dust, the old man's posture was very low, and he actually greeted him as a subordinate courtesy.

"Hey, don't, don't, that's a bit too much. If the subordinate official is at fault, it is all the Wasp's fault, you can punish him, and the official will never interfere! ”

This old eunuch is the personal entourage of Emperor Shenzong, and his status in the palace is very high, and the emperor is reluctant to send him out of the palace if there is generally nothing very important. Since it came out, it must have a holy decree, and the last time it is also a middle decree, the more polite it is, the bigger the matter.

"The lower official went to the Ganliang Road Metropolitan Governor to take on official business, this is an official document of the imperial court, and I also ask Lord Shuai Si to check it." Pei Ying still had the same dead face, and handed over the official document without hurrying.

"Ahh This, this, how can this make ......" Hong Tao's mouth opened widely, he thought that Emperor Shenzong might send someone to spy on him, but he never thought that it would be Pei Ying. The appointment on the official document is almost the same as himself, which is not only accepted by Ganliang Road, but also holds the position of Huangzhou.

"How can you not do it? Could it be that Lord Shuaiji wants to disobey! Pei Ying didn't have any sense of humor at all, and went online as she spoke.

"Don't dare, don't dare...... It's just that Huangzhou is a bitter cold place, and Pei Zhonggui is old, so I'm afraid he can't bear it. "Hong Tao is the most reluctant to cooperate with this old eunuch, he has been in the palace all his life, accompanied the two emperors, has reached the peak of eunuchs, and has no family, basically has no desires.

Didn't the ancients say that if you don't want to do it, you are strong. Pei Ying has watched palace fights and court battles all her life, and maybe she has practiced it, she is an extremely experienced old fritter, and she is not easy to fool. I can't kill him in an unknown way like I did with Wang Zhongzheng, that will make the emperor very angry, and the consequences will be very serious.

"As long as you don't die like Wang Zhongzheng, you will be content with the corpse...... There is also a decree of the imperial court here, and I think the adults would prefer to see it. ”

Which pot is not opened, as soon as the name Wang Zhongzheng appeared in Hong Tao's mind, Pei Ying blurted it out, and glanced at Hong Tao fiercely when he said it.

It seems that the cause of Wang Zhongzheng's death is not that no one suspects, but Wang Shi is too secretive, and the means are indeed beyond the understanding of the ancients, they really can't find evidence, everything is just speculation.

“…… Hey, hey, your majesty is wise...... Wasp, quickly go to the emperor's temple with the official to offer incense and pray for His Majesty to live a long life. Master Pei, would you like to go together? After receiving this holy decree with the seals of the province of Menxia and the province of Zhongshu, Hong Tao couldn't help but laugh out loud.

It's all right! The proposal for currency reform in Huangzhou has finally been officially approved, and this news is more important than Pei Ying. But Hong Tao really didn't want to get along with this old eunuch, so he quickly found a very, very good reason to slip away.

"My lord, please take care of yourself......" Pei Ying had already looked at the sky with his eyes, and in his eyes, this little trick of the horse was not enough to wait.

The more anxious you are, the more you have to calm down, you shouldn't leave right away at this time, but you should talk nonsense with yourself, and then inquire about the movement of the DPRK and China. It seems that the horse has not made much progress in this regard, and the future political future is not optimistic.
