When the Minister of Taichang Temple returned to Taichang Temple, it was almost noon.

While eating his lunch, he ordered his men to start sorting out a batch of medicinal materials.

The reason why he was preparing to leave the warehouse was because he did not believe in Zhao Wujiang's gunpowder theory. Mixing sulfur, saltpeter, wood and carbon in a certain proportion, and then heating or violently colliding, it would explode, causing a large area of ​​damage.

In his view, this was completely untenable.

On the way to the Imperial Study Room, I heard from the Minister of War that the idea of ​​Zhao Wujiang came about after hearing the report from the Minister of War.

In other words, there was no experimental basis and no finished product at the beginning, and now everything is just a verbal theory.

For the sake of oral theory, a large number of medicinal materials were moved in and out of the Imperial Medical Office. The hard work of the officials of the Imperial Medical Office was simply in vain.

If he's not his direct subordinate, then he doesn't feel bad, right? Taichang Temple Qing complained in his heart while picking over the food.

He knew that the Minister of the Ministry of Industry would definitely test it himself and wait for the results of the Minister of the Ministry of Industry to come out. It would not be too late to ship the medicinal materials out of the warehouse in large quantities.

Now he just sent someone to send some sulfur, saltpeter, charcoal to the Ministry of Industry, and waited for the results.

However, in the view of Minister Taichang Temple, this thing called gunpowder seems to work that way in theory, but in practice it does not work at all.

I don’t know what Zhao Wujiang was thinking. He was so anxious that he didn’t verify it, so he just asked him and the Minister of Industry to do it.

The same goes for the emperor. It’s fine if he favors Zhao Wujiang, but partial trust and favor are another matter. In this matter, he obviously favors Zhao Wujiang.

After all, they are still young people... Taichang Temple Minister shook his head and drank a glass of wine. Young people thought about it one by one, and they were not as experienced as the old people like them.

Zhao Wujiang found some medicinal materials needed to make gunpowder from the imperial hospital in the imperial city and took them to a rarely visited hall in the palace.

He mixed sulfur, saltpeter, wood, carbon, etc. according to the corresponding proportions, stuffed it into a bamboo tube, and sealed it with mud from top to bottom.

At the same time, I made a simple fuse using flammable wooden rope to control the burning and explosion time of the gunpowder.

After everything was ready, he inserted the bamboo pipe into the snow, and the lead was more than a foot long.

Xuanyuan Jing watched Zhao Wujiang tumbling not far away with great interest.

She has complete trust in Zhao Wujiang.

"Your Majesty, did you know? I have always known how to make gunpowder, but I have never done it myself before."

Zhao Wujiang took out the Huozhezi and blew it awake. His expression was filled with emotion and his eyes were distant:

"Do you know why?"

"I don't know."

Xuanyuan Jing was puzzled. Since he had never done it before, how did he know that it would be useful?

"Because it's illegal."

Zhao Wujiang told a joke that made him feel emotional. He knew that Xuanyuan Jing would not understand.

He lit the fuse with a fire stick, and the fuse began to burn, getting shorter and shorter. He stepped back two feet, full of expectation.

The reason why Zhao Wujiang confirmed this is because gunpowder, one of the four great inventions of ancient China, was developed and improved step by step by countless ancestors.

Later, the simple formula of this gunpowder seems simple, but it contains real meaning.

The lead was getting shorter and shorter, Zhao Wujiang stood in front of Xuanyuan Jing, his eyes burning.

The next moment.

A slightly dull explosion sounded on the snow.

The bamboo tubes were directly blown into pieces, and most of them were charred black and dyed with a mixture of red and blue flames.

A small crater more than two feet wide appeared on the snow, and the snow water with a radius of one foot melted, leaving it completely black.

The pungent smell of burnt gunpowder floated in the air, drifting in the wind.

Zhao Wujiang took a deep breath and shrugged his nose. The smell was really unpleasant.

But I really miss it, like the smell wafting in the streets and alleys after every household sets off fireworks during the New Year.

Xuanyuan Jing was shocked, his heart was in over his head, his face showed both surprise and joy, and he murmured to himself:

"This...is gunpowder?
