I think that when he was in Ningyuan City, Sun Yuanhua was a civil official and an official from the Liupin Imperial Court.

Gu San's family was just a lowly craftsman, and Gu Shanhai, who was eighteen years old at the time, didn't even dare to raise his head when he saw Sun Yuanhua kneeling on the ground.

Today's scientist is lifeless, he fell from the clouds to hell, and almost lost his life, he was already disheartened, and he didn't dare to refuse to be pulled by the enthusiastic Gu Shanhai to visit.

Because Sun Yuanhua is now a white body who has been stripped of his fame, or a sinner who has been assigned to Hainan Island, Gu Shanhai is obviously a six-rank official in the imperial court, how dare he be disobedient as a sinner.

Of course, Sun Yuanhua didn't know that Gu Shanhai, a six-rank civil official, was privately appointed by Huang Sheng, and he was not a man of rank or a scholar at all, but he was actually a blacksmith from a hereditary craftsman like an ant.

This is the essential difference between the Huang family system and the Ming Dynasty, Huang Sheng does not have prejudices about the Ming scholars, but it depends on what books everyone reads and whether they are stupid.

Not all people who read books can increase their knowledge, and if they read certain propaganda books, they will become stupid, and if they read books about cults, they will become crazy.

The Huang family all reads, and they all read practical books, and now the people of the Huang family system know about it. Reading the books on strange and obscene skills in the mouth of the great master can become an official like the Huang family, and the enthusiasm for reading technical books is high.

The former blacksmith became a civil official of the sixth grade, although the imperial court did not recognize it, but the Huang family system recognized it, and they vied with each other one by one.

In Hainan Island, there are the vast majority of civil officials like Gu Shanhai who are from artisan families and do not know how to read the four books and five classics, and they all have the ninth to the sixth grades, and they are all cultural people who graduated from the new school, or went to adult night schools to complete their studies, and they all have professional knowledge.

The Huang family system does not engage in kneeling and worshipping, and the common people only need to clasp their fists and salute when they see civil and military officials.

The high-spirited Gu Shanhai finally greatly satisfied his vanity and a sense of accomplishment in front of Sun Yuanhua, who existed like a mountain in the past.

After only three days of following Gu Shanhai to watch the flowers, Sun Yuanhua, who was dead, was itching again.

He was attracted by too many advanced production processes, many of which he had once fantasized about, but unfortunately he was unable to put them into practice due to the huge requirements, and now they all appeared in front of him one by one.

He had conceived of how to produce steel plates before, and when he saw the Hainan Island Rezha workshop, he saw a steel plate with a width of one step and a thickness of three or four steps in a half inch, and he immediately felt an eye-opener.

Hot rolling is a process that needs to heat the material during or before rolling to change the shape of the raw material again, and generally the ingot is heated above the recrystallization temperature.

Between the rolls that rotate up and down, the reddish ingots and billets are constantly squeezed to thin and widen the edges.

To put it simply, the rolling steel plate and the rolling pin rolling noodles are almost the same, after the rolling pin extruded and pushed many times, the dough is thinner and thinner, the same is true of steel, and the steel plate is gradually formed by multiple extrusion of the roll.

The key is that the roll should have enough weight to produce extrusion force, after the bulky upper and lower rolls to squeeze the ingot, gradually the prototype of the steel plate will appear, and then extrude many times after repeated rolling in the primary rolling mill, enter the finishing rolling mill, and the thickness of the steel plate below 16 mm can be obtained.

The craftsmanship that was not worth mentioning in later generations was of course spectacular in this era when there was no electricity, and the workshop for making steel plates had more than 1,000 strong laborers.

It takes more than a dozen gear sets and chains to drive a bulky roll, and it is of course inefficient to rely on water power, manpower, and animal power to drive these rows of steel rolls.

Therefore, the production of steel plates cannot go up, and steel plates with a thickness of more than 16 millimeters cannot be produced at all, but this has created a new era, and it is believed that in the near future, real steel plate warships will crisscross the seas.

Soon Sun Yuanhua was rejuvenated with enthusiasm for work, he was recruited by the arsenal, Gu Shanhai offered a guaranteed salary of five taels of silver per month to hire Sun Yuanhua to work, and also hired all the literate men of the Sun family to work with a basic monthly salary of one or two and a half taels of silver per month.

The Sun family was shocked during this period of time, and they were about to get out of their nerves, and they came to Yazhou thinking that they were just living this last life, but now they find that this is not a poor country at all, but a prosperous place, and they are secretly glad that God cares about it.

Who knew that good things followed, the family was able to get a high-paying job, and the master also got his favorite casting design.

At this time, the Sun family knew that Hainan Island was the territory of the old man's friend "Nanguo Gong", and the Huang family left his life behind, and it was also the intention of the "Nanguo Gong" to be able to come to Hainan Island.

The honest man Sun Yuanhua figured out the ins and outs with emotion, he knew that his friend's demand for weapons in the southern and northern wars would be endless, and he decided to use his spare heat to improve the weapons to make full use of his knowledge.

Zhang Tao and Sun Yuanhua are difficult brothers, and seeing that Sun Yuanhua and his family have been well placed, they can't help but take the initiative to find a job.

Within a few days, more than 100 members of his family got jobs, and he himself became a pawn in Changhua County, Yazhou, and took three sons and nephews with good military strength to participate in the management of the city, maintain law and order, and arrest bandits, which is equivalent to urban management.

The other two former county magistrates of the Ming Dynasty who were dismissed and took away their fame also found an errand for the secretary in the yamen, and many of their families entered the factory to work, and some of them were good at farming.

Zhang Taolezizi, the former chief military officer of the Ming Dynasty, worked as a city manager in the Huang family system, lived a carefree life, had something to be busy with every day, lived a very fulfilling life, and his mental state was actually much better.

Sun Yuanhua, the former governor of the Ming Dynasty, worked as a technician in the Hainan Island Arsenal, and he was busy every day, there were always endless drawings to draw, and there were always too many topics to be studied.

He is tired but happy, he will soon pass the exam to become an artillery designer, and it is estimated that it will not be long before he will pass the exam again to become an artillery design master.

Sun Yuanhua, who had been reborn, wrote a letter to his mentor Xu Guangqi, telling him what he had seen and heard on Hainan Island and his own situation one by one, and of course he was extremely satisfied with his current life.

Huang Sheng deliberately did not care about Sun Yuanhua, and let him use his professional knowledge to start as an ordinary designer, believing that with his level, he would receive new knowledge of the Huang family system, and everyone would be convinced to become a high-level leader of the arsenal in the future.

With Sun Yuanhua, a scientist, who is desperately responsible for product quality in the arsenal, he can transfer Gu Shanhai to open up a new world in the future.

The children and nephews of the Sun family are all Jiangnan scholars, and now they have no freedom in theory when they settle on Hainan Island, and the Huang family gives them freedom and hires them to work.
