The sky of history will always leave due space for those who have a heart. In fact, in life, not only historical figures, but also our usual small things, as long as we pay attention everywhere, they are all knowledge.

Although everything is difficult at the beginning, only by constantly accumulating these difficulties and increasing one's experience in life can one enrich oneself more and hone oneself. When the accumulation reaches a certain level, even if the problem suddenly appears, it will be targeted and solved.

Just like Master Xuanzang's arduous journey, from an unknown monk at the beginning, to now a famous Tianzhu, the Western Regions, and the Tang Dynasty Buddhist altar. All this is not only accumulated by him bit by bit, but also by virtue of his belief that he pays attention everywhere, the four seas are his home, and the sage is his teacher.

At the same time, it also responded to the proverb: no one knew the difficulties in the past, but once he became famous, the world knew it. No pain, no gain; Master Xuanzang's spirit of perseverance and inquiring about the root causes is not only worthy of our learning, but also worthy of our deep thought. Through so many days of contact, Wang Xuance naturally learned a lot from Master Xuanzang, especially the spirit of tracing back to the source and getting to the bottom of things.

When faced with new things, some people reject them, and some people lead them. Just like this world, there are always two opposing sides to everything, and the spear and shield never stop.

black powder, one of China's four great inventions; His invention was purely accidental. Needless to say, everyone also knows that this is exactly what the predecessor sage Ge Hong accidentally discovered when he was refining the pill. With his creation, there was a successor to the inheritance.

In the early stages of gunpowder, it was only seen as an elixir; But slowly, people discovered that his explosion seemed to contain a huge amount of energy. So, some people pondered this, if this explosion was improved, what kind of exquisite elixir would be refined? In ancient China, there has always been no shortage of such experts in answering questions, and if there is a doubt, there will naturally be a solution......

With the passage of time, the Chinese's understanding of black powder is not only in the simple refining of pills, but also in the improvement of pills. Instead, through thousands of experiments, it developed into the medical aspect of removing miasma and disease.

This incident, explained by modern people, is that it was precisely because of the presence of saltpeter that this explosion was able to suppress the plague caused by the bacteria and viruses that were not very strong at that time. This is a remarkable discovery in the 300-year history of the invention of black powder.

Since it was discovered that this explosion could ward off miasma and suppress the plague, it was natural to find ways to make it easy to store, easy to transport, and easy to use.

With the beginning of the New Year, every household will burn bamboo, and the crackling sound will naturally drive away the "Year of the Monster". So some people pondered this, and put black powder into the bamboo tube, not only the sound of the explosion was far better than that of bamboo, but also drove away the miasma. In the face of such an easy-to-use, so useful, and such a high-tech thing, how can it not be used to replace the simple act of burning bamboo!

And all this is thanks to one person, Li Jin, the originator of firecrackers who lived in the early years of the Tang Dynasty. It was his research on black powder that led to the continuous progress of later generations. His connection should be remembered forever by our future generations.

Since the early years of the Tang Dynasty, Gaozu Li Yuan set up a cannon supervisor and let Li Yuan personally take charge. Although new products appear from time to time, the impact is not very large. It is only in the past few years, with the increase in the number of tests and the improvement of black powder, that the manufacturing process of the lead has been slightly improved, and it has developed by leaps and bounds.

If it weren't for the gorgeous fireworks on the Lantern Festival night in the nineteenth year of Zhenguan, no one seemed to remember this Li Jin. Therefore, he is also a blockbuster person.

Of course, it is precisely because of his constant silence that Wang Xuance does not know much about him. Despite this, in the face of the earth-shattering firecrackers that can open the stone, Wang Xuance has already aroused Wang Xuance's strong interest. In addition, these days, I often listen to Master Xuanzang's teachings, so I thought about meeting this Li Zhen for a while.

I saw that on this day, a white cloud was scattered, dotted in the blue sky; A breeze blew by, not only making the trees nod and smile, but also making a pair of birds cut through the sky; The weather with light clouds and light wind not only looks quiet and beautiful, but also presents a very natural appearance.

At the south entrance of the city, under the old locust tree in a courtyard, Zhou Zeng and Chen Maocai were playing against each other at the stone table in the courtyard. Although the two of them have been a lot more idle during this period; But the quarrel caused by their game made people very irritated.

No, it didn't take long for the quarrel between them to start again. Even so, the two of them were like children, and not long after each quarrel, they reconciled like this, so that no one bothered to persuade them.

Of course, the cause of the quarrel was because of Zhou Zeng's problem, this arrogant person was inferior to everyone in intelligence in addition to being better than everyone else. Especially in this aspect of chess, the brain melon seed is often not as flexible as this Chen Maocai, so every time he always regrets the chess, there is a contradiction between the two of them.

Hearing that the two were arguing again, Wang Xuance was quite leisurely, and suddenly felt a little impetuous. So he threw down the ancient book in his hand, walked out of the study, and said to the two people in the courtyard: "Don't quarrel, go out for a walk with me." As soon as the two heard this, they immediately stopped arguing.

"Where are you going, big brother? They asked in unison.

"Don't ask so much, just follow me".

So, they threw down the chess pieces in their hands casually, and followed Wang Xuance out of the mansion. After leaving the house, I first walked a few hundred meters to the east, then walked north along the lively and bustling Suzaku Street for about a mile, and then turned west to reach the destination. It's none other than the Artillery Superintendent.

"Big brother, I heard you say last time, that firecracker can open stones, it is very powerful, so dangerous, what are we doing here?" Zhou Zeng casually purred out.

"Usually five big and three coarse, I didn't expect to be so timid this time." After Chen Maocai finished speaking disdainfully, he immediately said with a cleverness: "Alas, looking at your uneducated appearance, I am anxious for you, let's also get a few firecrackers back to dispel the miasma."

Zhou Zeng still wanted to defend a few sentences, but was interrupted by Wang Xuance: "You two are poor, let's come this time to ask people for advice, what kind of explosion method is this thing, how to make a big firecracker."

In fact, Wang Xuance took the two of them, and the purpose of coming this time was very simple: just see how this thing is used truthfully. Because he deeply felt that such a great power, if it could really be applied to the battle array, it would be like a tiger with wings.

When they came to the door of the gunner, they immediately reported their names. When Menzi heard the intention, he immediately turned around and went in.

Hearing that Wang Xuance was coming, the two who were talking in the house were suddenly quite surprised: What is he doing here?

The two people who talked to each other were none other than Li Chunfeng and Li Jin. Having said that, as soon as he heard that it was Wang Xuance, Li Chunfeng seemed to understand something, and with a slight smile, he nodded to Li Xuan. So, Li Jin immediately asked Menzi to invite them in.

The development of anything, like the application of black powder, is not achieved overnight. Therefore, no matter what we do, we must start from the grassroots level, start from the ground, step by step, step by step, only when the pace is firm, the road can be steady......
