Qin Mu inspected all the way, and when he returned to Ji'an Mansion, the people originally sent to Macao finally returned, and this time the governor of Macau, Shi Luobao, was still arrogant and still disdainful of the envoys sent by Qin Mu.

As early as the 32nd year of Jiajing in the Ming Dynasty, the Grape people obtained the right of abode in Macao from the Ming Court, and in the 11th year of Wanli, the Portuguese living in Macao established the Macao Council to carry out the autonomous management of the Portuguese community. However, 500 taels of silver had to be paid to the Ming government every year as land rent.

By the 44th year of Wanli, Portugal began to appoint the first governor of Macao, Carlo Gao, and it has been nearly 30 years since Macao, and Macao has changed six governors.

Unlike missionaries like John Tong, these governors did not come to Macao to preach, but to take charge of defense and to protect the interests of the Portuguese in Macao, so they disdained to give up advanced guns and guns for missionary rights.

Now Qin Mu urgently needs to recuperate and recuperate, and train the army, it is really not suitable to make a big move for Macau, so he has to send people again, ready to spend money to buy jishu, and now Xu Yingjie is making money in Jiangnan is going very well, and secretly Huang Lianshan keeps looting the rich gentry and wealthy households, which has caused a great vibration in Jiangnan, and the number of people who deposit money in Huitong Bank has increased exponentially, as long as the Portuguese are willing to sell jishu, it doesn't matter if they spend more money, and it is not too late to clean up the Manchus and the Portuguese again.

Qin Mu thought for a while and said to Yan Gaofei: "You send a message to Huang Lianshan, and ask him to send someone to the sea at the same time, go to the chicken coop and contact the Dutch, and see if you can buy some guns from the Dutch to make jishu." ”

"Yes, sir."

Qin Mu vigorously purged the officials along the way, and investigated many unjudicial officials where he passed, his itinerary is naturally known to everyone, when he returned to Ganzhou by boat, Sima An, Tian Yimu, Xiang Liancheng, Cui Feng and others led the army to welcome, and at the same time, there were still tens of thousands of people in Ganzhou spontaneously welcomed out of the city for ten miles;

Qin Mu walked out of the bow of the boat and waved to the crowd on both sides of the river. The crowds on both sides of the Ganjiang River are like mountains, and when they see Qin Mu coming out, they immediately cheer and thunder, in the sound of gongs and drums, firecrackers burst, and some people even ignore the cold, so excited that they rush into the river and dance, calling out loudly to Lord Qin, making Niu Wanshan and others who are guarding the left and right very nervous.

Dong Xiaowan took out a big coat and draped it on Qin Mu's body, and couldn't help but be surprised to see the people of Ganzhou welcoming Qin Mu so warmly. What she didn't know was. Countless people in Ganzhou were still suffering from war and struggling on the death line half a year ago, and it was a series of policies implemented by Qin Mu that enabled them to tide over the difficulties;

In particular, the implementation of the land reform policy has enabled countless poor people to have their own land, and land is more important than life in the eyes of the people.

There is also the unremitting efforts of Jingtian one acre, for Qin Mu to carry out a personality cult, there are all kinds of miracles, most of the people in southern Gan believe that Qin Mu is the real dragon descended into the world. It is the purple microstar who came to save the common people;

And Qin Mu went out with 2,000 troops, defeated Zhang Xianzhong's army of 450,000 troops, and also beat Zuo Liangyu's 200,000 army all over the ground to find teeth, these almost mythical achievements. further confirmed the rumor that he was a true dragon, and the people's respect for him was pushed up again and again, to the point of no return.

Like Dong Xiaowan, Xu Yongshun, who came along, was surprised to see all this. This little grandfather couldn't help but have a quick turn of thought, and his eyes looking at Qin Mu became even more complicated.

When the ship docked, Sima An and others stood on the pier. The mood was also very excited, just after a few words of greeting, Qin Mu unexpectedly got a news, so he hurried into the city and rushed to a large workshop located in the south of the city.

When he was in Huichang, Qin Mu asked Xu Yingjie to find a lot of skilled craftsmen, and later set up a firearms department in Changsha, and transferred some of them, considering the inconvenience of Huichang's material supply, the rest of the craftsmen also moved to Ganzhou City.

As soon as Qin Mu arrived, Zou Yan, who was in charge of the workshop here, immediately brought him to the front of a tall device, and as soon as he got closer, Qin Mu smelled the pungent smell of sulfuric acid, and he couldn't help but be overjoyed.

Zou Yan introduced: "The governor, the villain, etc., according to the essence method of refining stone gall recorded in the ninth volume of the "Yellow Emperor Jiuding Shendan Sutra" written by Gu Gangzi, through the way of dry distillation of stone gall, the sulfuric acid that the adult said was refined, this concentrated sulfuric acid is really as the adult said, it has strong corrosiveness, adult, small one, take some shiyan to show the adult. ”

"The Yellow Emperor's Nine Tripod Divine Pill Sutra?" Qin Mu asked curiously.

"Yes, my lord, Gu Gangzi was a Taoist in the Tang Gaozong period, and he was annotated with the "Yellow Emperor Jiuding Shendan Sutra", which recorded in the ninth volume of the method of refining stone gall to extract the essence."

Qin Mu was surprised, the Chinese Taoist priests were really amazing, not only refined gunpowder, but according to Zou Yan, they would refine concentrated sulfuric acid as early as the Tang Dynasty?

"Can concentrated sulfuric acid be refined in batches according to this method?" Qin Mu asked expectantly.

"Lord Hui, Jishu is no longer a problem, as long as the raw materials are sufficient, and then expand the refining scale, it is feasible to extract a large amount of concentrated sulfuric acid."

"Good, good, good." Qin Mu couldn't help but say three times in a row, you must know that sulfuric acid is known as the mother of the chemical industry, and many things are inseparable from it, such as sulfuric acid in the composition of nitroglycerin.

Qin Mu was a soldier in his previous life, and he knew very well how nitroglycerin was made, and he dropped half of glycerin into a mixture of one part nitric acid and two parts of concentrated sulfuric acid, which was nitroglycerin, a strong liquid explosive.

The three raw materials of nitroglycerin, glycerin, sulfuric acid, and nitric acid, among which glycerin is the easiest to extract, and hydrolyzing animal fat with a strong alkali will obtain sodium fatty acid (which can be used to make soap), and the by-product is glycerin, and there is no problem on jishu.

Now it's nitrate, sulfuric acid is refined, is nitric acid still far away?

As long as the three things are together, the raw materials of yellow explosives are basically complete, and then through the "warming method" invented by Nobel, nitroglycerin can be turned into safe and reliable yellow explosives.

This is also the reason why Weishenme Qin Mu left all his affairs after hearing that concentrated sulfuric acid was refined, and couldn't wait to come over to see what was going on.

In fact, whether it is black powder or yellow powder, as long as there are raw materials, it is not difficult to make, the key is to know the method.

In this day and age, who knew that it was possible to make soap from highly salty hydrolyzed animal fats, and at the same time to refine glycerin?

Who knew that mixing glycerin with sulfuric acid and nitric acid could make a powerful yellow explosive?

Some things are very simple when you know the method, but if you don't know, you don't even have a basic concept, and you can't talk about anything. Many things are invented by coincidence.

Qin Mu's advantage is that he knows such a concept, as long as he lets craftsmen like Zou Yan study in this direction, he can take a lot of detours, and sooner or later he will get the desired result.

Zou Yan took some concentrated sulfuric acid and carefully dripped it on a piece of silk cloth, the silk cloth was quickly corroded off, seeing this effect, Qin Mu nodded again and again and said: "Yes, yes, but this thing is very dangerous, you must be careful when you operate, all finished products must be guarded by special personnel, not placed at will, and at the same time, all production methods must be strictly confidential, whoever leaks it will be a capital crime." ”

Zou Yan hurriedly replied: "Don't worry, the governor will definitely obey the adult's orders." ”

Qin Mu turned his head to Sima An and said, "Mr. Sima, all the craftsmen involved in this work will be rewarded with one hundred taels of silver, and Master Zou will have the greatest credit, and the reward will be doubled." ”

"Yes, sir." Sima An hurriedly ordered someone to withdraw the silver.

Zou Yan not only won a heavy reward, but Qin Mu changed to call him "Master Zou", which is amazing, the identity of the craftsman in this era is extremely low, Qin Mu, as the governor of the third grade, is not a simple governor, he actually called him "master", so he was flattered, and sincerely panicked and asked for guilt again and again.

"Master Zou doesn't have to be like this, no matter who it is, as long as there is an outstanding contribution, they should be respected accordingly, now the sulfuric acid has been refined, but this is far from enough, you have to make persistent efforts to refine the nitric acid I said as soon as possible, and there is thunder mercury, but also pay close attention to research. These are very dangerous things, and you must strictly follow the booklet I gave you last time, and you must not be careless, otherwise it will inevitably hurt your life. ”

"Yes, yes, don't worry, the governor can rest assured, the villain must be careful."

Under the guidance of Zou Yan, Qin Mu carefully looked at various other studies, discussed with them, summed up experience, and spent most of the day before leaving the workshop.
