"The princess is not better today, this is the beef bone soup that my mother personally cooked, which can increase strength, I brought you some today!"

Chen Xu carried a small pot of soup with a wooden lunch box and followed the palace and the chamberlain into Huayu Palace, looked at Ying Shiyan who was sitting on the couch and said with a smile.

"Thank you Lord Hou for your concern, Shi Yan is much better today!" Ying Shiyan happily got down from the couch and saluted Chen Xufu.

Ying Shiyan's emaciated face had a touching red face, her complexion was much better, and she returned to normal after eating and drinking every day, so the whole person also regained a little bit of her former look.

The so-called heart disease also requires heart medicine, just because of Chen Xu's appearance, she was rescued from the brink of death at once, and then after the decoction and food supplements carefully prepared by the imperial doctor and the imperial dining room, three days passed, and Ying Shiyan also completely got rid of the shadow of death.

And after eating rice porridge and light food for three days, Chen Xu felt that he could replenish the princess's body a little, so he brought a can of beef bone soup stewed by his mother today.

And Chen Xu has to go to the palace almost in the morning and afternoon for the past three days, about half an hour each time, mainly to observe and take care of Ying Shiyan's situation, and then chat with her at the same time and tell stories to let her relax, since the emperor promised to marry the fifth princess to himself, Chen Xu is naturally worried that the princess who has not passed the door will be raised to death again.

If I marry another princess who has died, I am afraid that the goal of three wives and four concubines will not be achieved in this life.

And there is also a little wife who has already been booked, Meng Yi's youngest daughter Meng Wan is estimated to be in the soup, and Meng Yi will definitely regret it.

If a wife marries a person who dies such a heinous and vicious wife, she will inevitably be spurned by all the women of the world.

As the saying goes, the eldest husband is not in trouble without a wife, but the eldest husband is most afraid of his wife.

Chen Xu can make up that scene in his brain, and everywhere he goes, women are changing, and they are avoiding him like a plague when they are eighty and eight years old, which is really ...... It's terrible!

Watching Ying Shiyan finish drinking a small can of beef bone soup, Chen Xu accompanied her to tell the story for a while before leaving the palace, and then went directly to the Academy of Sciences without going home.

The gunpowder laboratory is a separate warehouse in the Academy of Sciences, and there have always been only two dumb slaves here, except for the two dumb slaves, no one is allowed to approach without Chen Xu's permission, and there are four Xuanwu guards guarding the door for twelve hours, which is definitely the most heavily defended place in the Academy of Sciences.

The saltpeter mine that Chen Xu had arranged for Zhao Qing to look for had been found, and it was transported from Shu County, and I heard that Longxi County also produced a lot of output, and it had been transported back thousands of catties through caravans one after another.

Because saltpeter is not pure potassium nitrate, it is relatively safe in transportation, so Chen Xu used a warehouse in the factory outside the city to store saltpeter mines, and when he wanted to use it, he used a wooden pestle to plow it into fine powder and then put it in water to boil, and then boiled dry after removing the precipitated impurities and residues, and finally got a very high purity of potassium nitrate, and potassium nitrate will absorb a lot of heat when dissolved in water, causing the water temperature to drop or even freeze. In this way, the big summer will create a cold and terrifying feeling.

Now Chen Xu didn't plan to make gunpowder on a large scale, so he asked Zhao Qing to stop after getting a few thousand catties, but the sulfur still asked Zhao Qing to arrange people to refine and search on a large scale.

Because there are not many sulfur in China, it is generally found in places where volcanoes are more active, and there is no way to reduce sulfur from sulfur in iron and copper ore at present, and only natural sulfur can be found from nature, so sulfur production is the biggest bottleneck of gunpowder, but no matter how rare it is, once the state machine is used to find it, it is natural that you can get a lot of it quickly, so at present, sulfur has also been made thousands of catties, and after grinding and washing with water to repeatedly filter and remove impurities, you can also get relatively pure sulfur. Coupled with the willow charcoal that was directly sealed and dried in a crucible, these three granular black powders made in strict proportions were completely no different from the most powerful black powder in later generations.

And this kind of gunpowder is now made by two dumb slaves every day, with the simplest tools, with the simplest method, twenty or thirty catties per day, and hundreds of catties of high-quality black powder have been produced for more than a month, and for the sake of safety, these black powders cannot be stored in the Academy of Sciences, so these gunpowders are sealed and transported to the factory outside the city, and a basement is specially built, locked in the ground with an iron door, and Yingbu is arranged to guard it closely, and no one is allowed to approach except Chen Xu.

A few days ago, Chen Xu successfully developed the fireworks bomb, but to celebrate this unprecedented victory, Chen Xu also planned to make the celebration more lively, prepared a full fifty rounds of fireworks bombs, and then made some small fireworks, and then took them back to the house for Xing'er and Yu Ji to play.

Fifty rounds of fireworks, it seems that the number is not much, but there are only three people in the gunpowder laboratory, and it took three days just to configure several colors of gunpowder balls, but today it is almost completed, and many printed proofs and misprinted waste newspapers were brought back from the newspaper hall, and several helpers of the Academy of Sciences rolled fifty or sixty paper tubes with the same thickness and length as the body of the fireworks, and the last task today is to put the gunpowder and fuses into them and seal them, and all the fireworks.

After finishing the fireworks bomb, it was almost time, Chen Xu went to Huayu Palace to visit Ying Shiyan again, and found that her complexion was much better, so he returned home for dinner.

"Husband, my mother said that I want to go out of the city to worship at the Taiyi Temple tomorrow, I'm afraid that the potion in the gourd has run out!" After eating, it was still early, Chen Xu slipped to the panda park, and Shui Qingrou also came over and whispered.

Chen Xu also guessed that there should be results in the next two days, so he was not too surprised and said: "Tomorrow you go with your mother, bring a weapon so that you can take care of it, you don't have to worry about other things, I and Brother Wuya will arrange it!" ”

"Okay, the husband himself should also be careful, these Fang Dao warlocks are not all swaggering and deceiving, and there are many capable people among them, and the husband should also remind the senior brother not to be careless!"

"Hmm~" Chen Xu nodded.

At present, these Fang Dao warlocks are actually the origin of Taoism in later generations.

The origin of the Taoist school is very early, can be traced back to the two emperors of Taigu, that is, Fuxi and Shennong, and to the era of Xuanyuan, the concept of Taoism began to gradually mature, with a more systematic theory, so Xuanyuan Yellow Emperor was also regarded as the originator of Taoist apprentices, and later Lao Tzu inherited the Yellow Emperor's idea of governing the country and the world to further carry forward the Taoist concept, forming the most universal and famous Huang Lao School during the Warring States Period, and the following hundreds of schools, including Confucianism and Mojia, were almost deeply influenced by the Huang Lao School.

Therefore, Chinese civilization can actually be regarded as originating from the Taoist school, as for the later generations to use Confucianism to govern the country or because it is crooked, it can be seen from the admiration of later generations for Lao Tzu that no matter how Confucianism changes the development and inheritance of civilization, it has never been able to get rid of the influence of Taoism, which is a genetic inheritance precipitated in the bones, and it may not be erased in tens of thousands of years.

The Qin and Han dynasties were the period when Taoism gradually took shape.

In the process of the world from chaos to great governance, the Huang Lao school also gradually began to differentiate, part of the WTO to run the country, part of the pursuit of immortals, and then formed Taoism, a unique religion that influenced Chinese civilization, and due to differences in ideas, Taoism has actually not formed a unified school, alchemy, qi training, and the development of the respective drawings, and finally was almost beaten all over the body by the outsiders Buddhists with a strong Vajra palm and a fist of the Tiger Arhat.

The development process of Taoism can actually be regarded as a microcosm of Chinese civilization, from glory to decadence, from the Qin and Han dynasties to the Qing Dynasty, the will of this country has been constantly depressed, gradually blind and dazed, not knowing where to develop, so it introduced a theory that even foreigners can't look down on, and then completely abandoned the inheritance of Chinese civilization.

To get back to the point, these Fang Dao warlocks who were previously raised in the palace by Qin Shi Huang are many of the crazy followers of the Immortal Dao, they think that there must be immortals in this world, and there must be a way to live forever, and Qin Shi Huang was bewitched by these Fang Dao warriors, and naturally also yearned to be an immortal human emperor, so the two sides hit it off, Qin Shi Huang contributed money and people, and these Fang family warlocks came out with technology, and established the Great Qin Immortality Research Institute, specializing in the study of immortal methods.

However, this research institute has not yet started to operate, and the boss has dismissed the research institute when he comes back from a trip, and all the employees have been laid off, so he finally squeezed close to the research institute and was ready to mix into a high position or even prepare to show his skills, and a group of Fang Dao warlocks were all filled with grief and indignation, and finally slowly turned their eyes on a guy.

Because this guy is very excessive, even more excessive, he directly declares that he is a disciple of the Immortal Family, not only shameless, but simply shameless to the extreme.

So some people were dissatisfied and decided to destroy the foundation of Chen Xu, a disciple of the Immortal Family, cut off his spiritual root and destroy his skills, and completely turned the disciple of the Immortal Family into a wasted person.

However, it was obvious that this move had aroused the vigilance of the two warlocks around Chen Xu who were also Fang family warlocks, that is, Yu Wuya and Shui Qingrou.

Even if Yu Wuya didn't know about this matter, the water that accompanied Chen Xu to sleep every day would naturally say it, if Chen Xu married an ordinary woman, I am afraid that he would really be able to get into the Tao, but obviously the disciples of Liezi, as the inheritors of the most orthodox Taoist school, are a little bit stronger than the so-called fairy Dao and those swaggering Fang family warlocks.

Therefore, after receiving a gentle reminder from Shui, Chen Xu immediately found Yu Wuya, asked him to go to the factory outside the city to find Yingbu with his token, and secretly mobilized fifty guards guarding the factory to enter the city, and went to the Academy of Sciences to secretly mobilize ten Xuanwu guards, all of whom were disguised as civilians, merchants, peddlers and pawns, and then waited for tomorrow to follow Chen Jiang's family to the Taiyi Temple outside the city.
