Where the gunpowder exploded, the surrounding vegetation had been completely blown away, leaving only bare land.

There was a large black powder on the ground, which was the toner, and there was a small pit on the ground, and the area of the pit was not large, about the size of a bowl.

Jing Zetian shook his head secretly, the power of this gunpowder explosion was simply incomparable to the explosives that exploded stones he had seen in his previous life, but in this era, it was also the most powerful.

"Okay, you go back and guard, I'm still going to try." Jing Zetian said to everyone.

When they saw the power of gunpowder, their hearts were steady, and they hurriedly took their places, guarding against death, and they all understood why Jing Zetian was so cautious.

When everyone left, Jing Zetian configured the explosives again, he was here to mix the things brought by Yang Zhanfei into the gunpowder, and add other substances without changing the power of the gunpowder, the main purpose of this was to keep it secret.

The formula of gunpowder is very simple, just three powders, as long as someone knows the material, as long as they spend time researching, they will definitely work out the appropriate ratio, and as a last resort, Jing Zetian can only experiment with adding other things to confuse.

Jing Zetian successively added some solid materials such as cinnabar and lime, and when he mixed the formula of three gunpowders such as sulfur powder, he spread these additional materials on the surface, trying not to mix with the main materials, and then experimented again.

may have lived the favor of God, and Jing Zetian's second experiment was still a smooth success.

The experiment went so smoothly that Jing Zetian was a little incredible.

In order to ensure the accuracy of the test, Jing Zetian tested it again, and the results were still very smooth.

In order to save materials, Jing Zetian could only stop the test, and then use the remaining materials to make explosives one by one.

A total of more than 800 catties of things, Jing Zetian picked and chosen, and made more than 30 packs of gunpowder, which is not bad.

It took Jing Zetian three or four hours to make gunpowder, and he was sweating profusely when he was busy.

Jing Zetian gently placed the explosives package, and from these explosives bags, he randomly picked three packets, placed them in the distance, and directly ignited them with saltpeter powder.

The three gunpowder packets that were spot-checked immediately still made a "BOOM" sound, so after that, Jing Zetian was completely relieved, and the rest could only depend on the will of heaven.

When everything was tested, Jing Zetian called Yang Zhanfei and the others back.

"Ergou, you pack these gunpowder packets carefully, you can't let these gunpowder bags collide violently, you can't see water, and you can't see open flames, otherwise there will be an explosion just now." Jing Zetian said cautiously to Ergou.

"Whoa." Ergou also knows that these gunpowder packs are not ordinary things, and they should be treated with care.

"You find a safe place, you must stay away from people, put these things away, wait for Xiaobai to come back, tell him today's events, and by the way, let him buy more saltpeter powder, and then I will teach you how to use this thing, then we will have a greater chance of robbing relatives." Jing Zetian explained carefully.

"Whoa." Ergou still replied simply.

This makes Jing Zetian appreciate it very much, he doesn't talk much, he is reliable, and he is a talent.

"Your Highness, can you give me something to play with?" Yang Zhanfei on the side looked at the gunpowder bag with hot eyes.

"It's an extraordinary time, I'll give it to you when I have a chance in the future, you remember to keep this matter secret, your parents can't say it, otherwise, I'll tie a gunpowder bag to you and blow you to ashes." Jing Zetian said viciously to Yang Zhanfei.

"Okay, Your Highness, I see." Yang Zhanfei said reluctantly.

"Well, when I teach Xiaobai to use it, you can come back and let you play with it." Jing Zetian saw that Yang Zhanfei was a little lost, and felt that he couldn't live with others, so in order to help himself, he was busy without regrets, and said comfortingly.

"Oh? Okay, I'll be sure to come then. Hearing Jing Zetian's words, Yang Zhanfei, who was like a defeated rooster, cheered up.

"It's not too early, let's go back." Jing Zetian looked up at the sun, and at this moment the sun was already in the west, at least past noon.

Under the leadership of Jing Zetian, the large army rushed back, leaving behind devastated artillery craters.

--- dividing line---

Today, when Jing Zetian was busy making black powder, outside the city of Hua'an, a group of people wearing fur and animal skins, with messy hair, sloppy beards, and huge copper rings on their ears, these were the representatives of the welcome mission of the Wusi Khan, and they walked towards the city of Hua'an under the escort of the Dahua army.

"The third prince, the place where the Han people live is really beautiful and lively, and the beauties on this street also appear one after another, which is really eye-catching." A bare-headed strong man in the Youth League said to the young man beside him.

"Hehe, the Central Plains is the place we have always wanted to conquer by the grassland people, and I believe that it will not be long before the iron hooves of our Youth League will be able to gallop on this land to their heart's content." The young man said confidently. This man is the third son of Uskhan Khan, Merton, the supreme leader of the wedding procession.

The language they use to communicate is Qingmeng, and the Dahua soldiers around them can't understand it, otherwise, no matter how extraordinary their identity is, they won't stand here so safely.

Among the Dahua soldiers, walking in the front, riding a black horse, wearing a black armor is Yang Zhanhong, who is only in his twenties, Dahua's five-grade general, General Yingyang.

Among the young second generation of officials, he is a good mix, he has killed the enemy on the battlefield, and he is deeply respected by the military bosses, and with the care of his father Yang Guangwu, the future is limitless.

The horse team was on the street of Hua'an City, and went straight to the palace along the main road, and along the way, the people of Dahua looked at them angrily, and if it weren't for the heavily armed sergeants around, they would have rushed up to fight.

Soon, they were outside the palace.

"Prince Merton, let your men wait at the gate of the palace, and you will follow me into the palace alone to meet Your Majesty." Yang Zhanhong's loud voice sounded, perhaps due to genetic factors, Yang Guangwu's sons have similar appearances and synchronized voices.

Prince Merton, as the child of the leader of the Youth League, as the person in charge of this wedding, is proficient in Chinese, so Yang Zhanhong's words, he easily understood.

"You wait outside the palace, and I'll follow them in." Merton did not refute Yang Zhanhong, but directly commanded his subordinates very cooperatively.

Merton's men apparently disagreed with this order, but given Merton's majesty, they only shouted a few words, and finally obediently stood outside the palace.

In this way, Merton unloaded his weapon and handed it to his general, and followed Yang Zhanhong towards the palace.

Yang Zhanhong couldn't help but glance at him when he saw Merton's cooperation with such awareness, in his impression, the people in the Youth League were all uneducated, impulsive and reckless people, but he didn't expect Merton to be so calm.
