Liu Wu was stunned, and the smile on his face gradually disappeared.

The Marquis was very concerned about the refinement of this thing before, and sent someone to ask about it many times.

Now, with progress, the Marquis is not so interested.

"Mr. Marquis, you'll know if you go in and take a look."

"Look outside." Zhang Jing was determined and had no room for negotiation: "Can this thing explode?"

"Yes." Liu Wu nodded seriously: "I tried it, it's extremely powerful."

Zhang Jingyi said, "Then take it out and give it a try."

Liu Wu had no choice but to nod.

After a while, a group of people took out a package. In addition to the suspected yellow gunpowder they extracted, there was also white sugar.

White sugar is very expensive in this era.

However, to some extent, white sugar is also a high-energy polymer. The so-called high-energy polymer is the energy released after burning.

At this moment, a group of people came out excitedly.

When Zhang Jing looked at the guy holding the package, he jumped and jumped, so shocked that his throat was about to jump out.

This group of people was not killed by the bombing, but it was really blessed by the ancestors and accumulated great virtues.

The guy holding the package immediately found the hill in the distance, and then stuffed the package between the rocks under the hill, and then he began laying the leads.

In fact, this thing cannot be exploded by the lead wire, and it must be impacted.

However, Liu Wu explained: "Mr. Marquis, we have put some black gunpowder inside. The lead wire is ignited, and the black gunpowder inside will explode. In this way, the thing will also explode.

Zhang Jingyi understood roughly, but he didn't say anything, just waiting for the effect.

After the leads were laid, a group of guys stopped and watched from afar with smiles.

Someone started lighting the fire.

The lead is very long, so Mars crackled with the leads and began to move towards the wrapping direction.

Zhang Jing was startled and asked, "How many times have you tried before?"

Liu Wu smiled and said, "Try it once."

"It's so big, too?" Zhang Jingyi asked curiously.

Liu Wu thought about it carefully before saying, "It's much smaller than this. Isn't the Marquis here today? So brothers, let's get bigger and see how the effect is!"

Zhang Jing suddenly shuddered, then glared at him and said, "Why didn't you say it earlier?"

As he said that, he ran back quickly and ran dozens of steps before stopping.

At this moment, the leads finally burned out.

First, I heard a rumbling sound, but the sound was obviously just an explosion of black gunpowder, and nothing surprising.

But then... it seemed that the explosion of the black gunpowder caused a huge vibration, and then... the thing in the package was suddenly released.

Zhang Jingyi first saw a ball of fire, exploding the rocks on the hills, and then... a deafening roar was released instantly.

Zhang Jingyi suddenly felt that his ears were already numb.

Then the huge flame rushed into the sky.

The big stones around immediately collapsed into gravel, and the flying sand and rocks rose into the sky.

At this moment, the earth seemed to have begun to shock.

Zhang Jingyi felt that his internal organs were about to be misplaced.

What followed was a wave of heat coming.

Then... the world suddenly became quiet.

The hill in front of me has become a scorched earth, leaving a huge bomb crater.

And Zhang Jingyi still couldn't hear the sound of this world.

He just gasped, and there were probably countless grass and mud horses running by in his heart.

Looking back, Liu Wu took out a tampon from both his ears and then grinned at him.

Zhang Jingyi: “…”

Zhang Jingyi's ears were still buzzing, and he could not hear the sound from the outside world.

But... he was still extremely shocked by the power of this thing in front of him!

This gunpowder is at least ten times more powerful than black gunpowder. No matter how bad it is, it is just an enhanced version of the power of fireworks and firecrackers.

And the gunpowder in front of you belongs to another concept.

It was finally difficult for Zhang Jingyi's ears to recover, but he still felt pain at this time.

Then he heard Liu Wu's voice faintly: "What do you think of the Marquis? Otherwise... let's try again, we are all hiding in the laboratory."

Zhang Jing's pupils contracted, and she was shocked again, and she widened her eyes and said, "You just put them in the laboratory?"

Liu Wu said for granted: "Yes, where should I put it?"

Zhang Jing vaguely felt that this man named Liu Wu must have smoke from his ancestral tomb.

Without the blessing of his ancestors, it would be a miracle that he could live to this day!

But as a person who still has a kind heart, Zhang Jingyi still cares about their safety.

So Zhang Jing said: "We have to build a special warehouse, which is farther away from the living and experimental areas. By the way, how many kilograms can this thing be produced in a day?"

"Ten kilograms."

"Ten kilograms?" Zhang Jing said: "I will give you more people. You have to teach them step by step. Not only that, you plan to make a list of required items every month. I will give you whatever you need. There is only one condition, that is, I will give you at least fifty kilograms a day, and... You have to have a rule, how to make this place like a Caishikou?"

When Liu Wu heard this, he hurriedly said, "Okay, I'll listen to the Marquis."

Zhang Jingyi said proudly: "I have raised the people here, now starting from their parents, wives and children! There will be a big house and someone will serve them, but there is one thing that people here are not allowed to leave without authorization. Here, I will build high walls to strengthen the vigilance... Also, if your salary will be doubled, is there any problem?"

Liu Wu was obviously satisfied and nodded directly: "Thank you, Marquis."

After giving the order, Zhang Jingyi said, "You guys clean up here first. After you go back, I will draw a charter and that's it."

Liu Wu couldn't help but frown and said, "Why, the Marquis doesn't go inside and sit, it's okay to have a sip of tea."

"I won't sit anymore, I'll be busy with all my life." Zhang Jing said: "A lot of things are waiting for me to deal with, and I can't get rid of them."

Liu Wu seemed a little regretful. He originally wanted Zhang Jingyi to go to the laboratory to sit and talk carefully. The process of refining this thing with his brothers was very tortuous.

However, it was obvious that the Marquis only looked at the results, so he said goodbye to Zhang Jingyi helplessly.

Zhang Jing returned to the county, but in fact, he was filled with excitement at this time. With that thing, the strength of this military academy is probably going to be higher than the next level.

But these guys repeatedly reminded them how dangerous the process of refining was, but they didn't care at all, and they were too big.

Thinking of this, he felt it was necessary to draw up another charter and carry out strict management.

After thinking about it, Zhang Jing started to do it and quickly drafted a charter, which was then handed over to Lu Xiangsheng, asking Lu Xiangsheng to do so.

But at this moment, Zhang Shun came.

As soon as Zhang Jing saw him, he smiled and said, "Why, what's wrong in the palace?"

"Your Majesty, please enter the palace immediately."

Zhang Jingyi said: "What's the matter?"

Zhang Shundao: "Tian Ergeng brought an urgent report. His Majesty felt it was of great importance, so he immediately asked his godfather to enter the palace to discuss it."

Zhang Jing didn't dare to be negligent, so he immediately set off and rushed to Xiyuan.

When I arrived at Qinzheng Hall, I saw Wei Zhongxian and Tian Ergeng and others.

Tian Ergeng seemed to be proud at this time, and Emperor Tianqi was also very excited. As soon as he saw Zhang Jingyi, he said, "Zhang Qing, sit down and talk."

Zhang Jing sat down and owed her body, saying, "Your Majesty, I wonder what's so urgent?"

Emperor Tianqi laughed and said, "The Northern Town Fushi came to report that the merchants had left the Korqin tribe, and this was clearly coming to the pass."

"Is that true?" Zhang Jingyi was not surprised by this.

The court made up its mind to force them to come back. They could not stay unless they wanted to die outside the pass.

There seems to be some progress in the peace negotiations in Liaodong. Because of this, Zhang Jingyi predicted that these people would not be willing to stay outside the dangerous pass. Since there are risks outside the pass, it is better to go back to the pass.

After all, their 100-year business has deeper connections within the city.

Although for them, the connections inside and outside the pass are actually mutually exploited.

But for the Mongolian and Jiannu people outside the pass, their value of use has disappeared.

However, the connections within the pass are different. These people who have received countless benefits on weekdays have become their blackmail targets. After all, once they are taken away, if they reveal something, countless people in the pass will be buried with them!

This gave the smuggling merchants led by the Fan family enough confidence.

Since this is the case, these civil officials and military generals who colluded with them at the time must find a way to protect them.
