The law and order in Chang'an City stabilized at an incredible speed, and although Qin Jin hadn't closed his eyes for a day or night, the previous military reports indicated that the rebels were about to arrive in the next two days, and they must be prepared as much as possible before that. Pen Fun Pavilion wWw. ｂiquge。 infoThe hardware facilities of Chang'an city defense are second to none in the whole world, regardless of the scale of the city wall or the scale of the moat, there is no other place in the world.

However, there is one thing that also makes Qin Jin a little dissatisfied, that is, the city walls in this era are not popular with bricks, so the exposed outside is all rammed earth. Out of preconceived impressions, he always felt that it was all rammed earth, not as solid as bricks. In the course of the inspection, he once mentioned to Zheng Xianli about the brick wrapping of the city wall, and Zheng Xianli thought at first glance that this could indeed increase the strength of the city wall, but when you think about it, it is difficult to count the amount of masonry labor involved.

What's more, this kind of big project can't be completed overnight, Zheng Xianli felt that Qin Jin's idea was really a bit jumpy, which made him a little baffled.

"Does the envoy want to wrap all the outer walls of Chang'an with bricks?"

Of course, Qin Jin also knew the difficulty, so he only waved his hand and smiled:

At this point, I thought of casually saying that it is better to have strong walls, but I have always believed that the most important thing is the people who defend the city. ”

"This is very true!"

The two men came down from the city wall and hurried to the ordnance prison. Qing Xuzi was there directing a group of craftsmen to grind gunpowder particles, and when he saw Qin Jin, he hurriedly trotted in front of him and bowed down.

Zheng Xianli was obviously a little surprised by the humble and humble attitude of Qing Xuzi, and in his impression, no matter whether he was born in Buddhism or Taoism, he would not show his grovel to officials, and this person was obviously very different from his impression.

"The method of making Jun granulate gunpowder is really clever, and the situation of large pieces of gunpowder being compacted and unable to burn is greatly reduced. ”

Qin Jin didn't have time to listen to Xuzi's compliments, so he only asked directly:

"How much gunpowder was produced?"

"After three days and nights, thousands of baskets have been produced!"

Qin Jin is quite satisfied with this speed, but it is not enough to have thousands of baskets, the use of gunpowder can greatly reduce the number of casualties in battle, so in the next upcoming battle, he has to use all kinds of primitive firearms to the extreme.

"Very well, can the production of gunpowder be faster, once the battle begins, the consumption may be huge!"

Qing Xuzi was full of confidence in this, and even patted his chest and assured Qin Jin that as long as he was given enough manpower, the production speed would be as fast as possible.

The most important thing in Chang'an City now is Ren, although half of the population has been run, there are still hundreds of thousands of people left, and the number of private enterprises alone has reached 100,000. Moreover, the number of people in the private sector is still rising, and after excluding the old and young women, the available Ding Zhuang will never be less than 100,000.

Although these people are ordinary people with little combat experience, as long as they are fully organized, their role is still immeasurable.

Zheng Xianli had long heard of the role of gunpowder in the First World War in Hedong, but now he only saw baskets of black powder, which was a little unbelievable, so he grabbed a handful from the basket and twisted it vigorously.

"This thing can kill?"

Looking at Zheng Xianli's expression of disbelief, Qin Jin secretly said that if this kind of thing would become an invincible killing weapon on the battlefield more than a thousand years later, he would definitely find it even more difficult to believe.

No matter how nice it sounds, it's better to demonstrate.

"Qingxu Zhenren, go to the treasury and get a few thunderbolts. ”

After Qingxuzi agreed, he personally led people to the warehouse, and after a while, he carried a basket of thunderbolts.

"Envoy, this thing doesn't dare to practice in the weapons prison, now there is gunpowder everywhere, if there is a little bit of spark sticked, this place may immediately become a purgatory on earth!"

Don't look at Xuzi Ping's giggling and hee-ha-ha appearance, but since presiding over the large-scale production of gunpowder, he first set up a rule of killing heads in the ordnance prison, and all fireworks are prohibited in the ordnance prison.

Zheng Xianli secretly pursed his lips for the Qingxuzi who was chattering with gods, and he didn't understand how a wise Qin envoy could also use this kind of pit to deceive and lie Fang Shi?

Whether it is a Taoist priest or a monk, as long as you do not seek the right path and bewitch the superiors, you will be poisonous insects. Zheng Xianli secretly thought that he must find an opportunity to suggest to Qin Envoy Jun that he get rid of this person as soon as possible, and cause a big disaster on the one hand. It's just that the show hasn't started yet, and he is not in a hurry to make a statement, so he only followed Qin Jin and Qing Xuzi to a large open space to the west of the ordnance prison.

Qin Jin waved his hand.

"Let's light a fire when you're ready!"

Qing Xuzi personally led people to bury fifteen or sixteen thunderbolts in the ground, and piled up a mound more than half a person high on them, leaving only a thick and long lead outside. At the same time, someone had already lit a torch and held it up to Qin Jin. Qin Jin handed the torch to Zheng Xianli again.

"Brother Zheng, I'll leave it to you to light the fire. Remember only one, and jump into that pit as soon as you light it, or you may risk your life!"

At this time, they were still thirty or forty steps away from the mound, when it was not close, seeing that Qin Jin and the others were all solemn and nervous, Zheng Xianli felt a little funny, he had never seen Qin Jin afraid of anything, how could he be afraid of this thing called a thunderbolt to this point?

From this, his curiosity also soared, and he had to see what could happen when a lead was lit!

"Rest assured!"

After taking the torch, Zheng Xianli strode towards the lead, and there was Qingxuzi's tireless advice behind him.

"Don't forget, click the lead and jump into the pit...... Jump into the pit ......"

Zheng Xianli smiled secretly, don't make the king was also frightened by the chatter of the Qingxuzi God, so his impression of the Taoist priest changed sharply.

When the torch approached the lead, the lead burst into flames, and the sizzling sound was extremely harsh. Seeing the sparks moving towards the mound at a very fast speed, Zheng Xianli thought it was funny, so he stood on the spot and watched fixedly.

"Jump into the pit, jump into the pit!"

Behind him, there was not only the urging voice of Qing Xuzi, but also the urging voice of Qin Jin. Zheng Xianli felt that Qin Jin's words could not be regarded as wind in his ears, so he struggled to jump to the dirt pit a few steps away, and as soon as his body was next to the bottom of the pit, he heard a thunderous explosion, and the whole earth trembled in an instant.

In an instant, Zheng Xianli was dizzy from the shock, his ears were roaring, and he couldn't get up after lying at the bottom of the pit for a long time. Until he stood up, he found that all around him was thick white smoke, and the breath he inhaled from his mouth and nose was also a strange stench.

At this point, Zheng Xianli was so frightened that he actually broke out in a cold sweat; if he was still standing on the spot, wouldn't he have been torn apart by the thunderstorm? Because he did not know the situation outside, he was afraid that there would be another thunderstorm, so he leaned back again.

It happened that a gust of north wind blew, and the smoke in the open space quickly dissipated, and then Zheng Xianli crawled out of the dirt pit with palpitations, but the scene in front of him shocked him again.

When I entered the eyes, I saw that the mound had long disappeared, but there was a large pit in the position of the mound, and there was still a faint smoke in the pit.

"This, this ......"

Even though Zheng Xianli was used to seeing battles, he was so shocked that he couldn't come back to his senses for a long time.

Qing Xuzi ran over again and smiled at Zheng Xianli.

"How, it's amazing, isn't it?"

This is not so much a question as a ridicule of Zheng Xianli. Qing Xuzi is so smart, how can he not see his disdain for his attitude, and now he scares this arrogant guy into a stunned appearance, just looking at it is very comfortable in his heart.

Zheng Xianli finally came back to his senses completely, and finally understood that Qin Jin was not bewitched by this clever Taoist priest, but that this black powdery thing really had a miraculous effect!

"If the envoy spreads this thunderbolt all over the outside of Chang'an City, and when the Sun Thief rebels arrive, they will all be ignited, won't they win without a fight?"

Qin Jin nodded and smiled:

"That's right!"

However, he agreed easily, but he knew in his heart that although Zheng Xianli's idea was good, there were many technical difficulties that were difficult to overcome. The first point is the moisture-proof of the lead, although the lead is flammable but also easy to get damp, as long as it is buried in the ground, I am afraid that it will not take more than an hour to have most of it fail due to moisture.

If a thunderbolt is planted in advance on a large scale, it will be at least one day in advance, so the seemingly simple and miraculous idea can only be deterred in the face of technical difficulties.

Qing Xuzi finally convinced Zheng Xianli, and when he saw that he was excited, he couldn't help but say a blow.

"The method you said made Jun think about it a long time ago, but the lead is easy to get damp, and if you bury it overnight, seven or eight times out of ten will fail......"

Suddenly, Qin Jin only felt that his forehead was cold, and when he reached out to touch it, it was a water stain, and it was snowing.

Zheng Xianli said:

"As long as the moisture is frozen, it won't come out, so won't it be enough to bury these thunderbolts in the snow?"

He has now gone from being suspicious of gunpowder to being admirable.

Qin Jin Dao:

"This is also a method, whether it will succeed or not, it will have to be experimented, in short, as long as the weapon is in hand, there are a thousand ways for the rebels to go against Hu to meet the king of Hades!"

As he spoke, the sky completely darkened, and Qin Jin let out a long breath.

"It seems that the rebels will not come back tonight, I don't know what will happen tomorrow!"

"It's a good thing that the rebels don't come today, so you haven't closed your eyes for a night or two, why not take this opportunity to sleep well and recharge your energy to resist the enemy in the future?"

Zheng Xianli's suggestion was indeed good, and Qin Jin also felt sleepy when he said it.

"Qin Envoy Jun can be here?"

Suddenly, a sharp voice came from the darkness, and everyone immediately heard that this man was a eunuch.

Immediately, an entourage stopped the eunuch and asked what was the matter with the envoy of Qin. After the eunuch asked Qin Jin about this, he shouted in a panic:

"Qin envoy Jun is not good, the East Palace is on fire, Wei is short of manpower, His Royal Highness the Crown Prince asks the envoy to take someone to ...... quickly"
