There was a loud "boom", and I saw that the wooden man and Trojan horse placed around the explosion point instantly disintegrated and flew into the sky. Although Xuanzong had been prepared for a long time, he couldn't see anything on his expression, but the shock in his heart was like a tidal wave, constantly impacting the bottom line of his military cognition.

What the hell is this? Why is it so powerful?

The scene around the explosion point was quite "tragic". Because Sima Lin ordered people to use the assembly method to make wooden people Trojan horses, the torso, legs, feet, and heads were all made separately, and under the blow of the powerful explosion shock wave, the wooden people and Trojans were scattered almost immediately and scattered all over the ground.

Yang Qing learned the lesson that the filling effect of stone arrows in the morning test explosion was not very ideal, and replaced the sputter in the bamboo tube with the smallest iron thistle, although it was still too big, but there was nothing else to replace for a while, so he had to do it. So when Zhang Nance immediately stepped forward to pick up a piece of "thigh" for testing, Yang Qing was the first to come up, he wanted to see what the effect of thistle terrestris was.

Ideally, it is pierced very deeply. Yang Qing nodded with satisfaction, if it was replaced with one or two times smaller, it should be able to completely penetrate the body of a person or horse.

Several guards of the forbidden palace behind Xuanzong looked pale, although the loud noise just now also frightened them, but looking at the "thigh" in Zhang Nan's hand, they immediately thought of assassination. If such a thing explodes around the Holy One......

"Yang Qing, is this thing difficult to make?" Xuanzong asked in a deep voice.

"It's not too hard. However, in order to achieve its effect stably, it still needs to be vigorously studied. What Wechen makes today is too rough. ”

"I want to hand it over to the Ministry of Industry and the Ordnance Supervision for development, what do you think?"

"Ministry of Works?" Yang Qing looked up puzzled. "Holy Lord, this is a weapon, why do you let the Ministry of Works participate in it?"

"Such a sharp thing, in addition to shining on the battlefield, private mining, construction, etc. must also be very useful." Xuanzong glanced at Yang Qing lightly.

"Never!" Yang Qing hurriedly objected when he heard this, his previous idea was the same as Xuanzong's, in addition to the use of gunpowder for military purposes, the role of gunpowder in the civilian sector should not be underestimated, and even for social and economic development than military promotion. But then I thought about it carefully, although I tossed out the black powder in advance at this half-baked level, after all, there were still a lot of problems that had not been solved, and I couldn't solve them myself. The mining and storage of raw materials, the storage and transportation of finished products, the entire management system, the confidentiality system, the complete grasp and application of the properties of gunpowder, development, etc., etc., can be solved at once? According to the experience of later generations, the development process of almost all high-end technologies has gone through the principle of military first and then civilian, and after a period of military use, all the conditions are ripe to consider whether it can be used for civilian use, several years, decades, or even hundreds of years! Although Yang Qing admired Xuanzong's "foresight" from the bottom of his heart, this is really impatient, especially since it is still explosive gunpowder!

"Holy Lord, please forgive Weichen for being rude. The new gunpowder technology is far from mature, and it is really not suitable for rapid popularization. First, this object is extremely dangerous, and it should not be touched by non-experienced people! Second, this thing is very powerful, once it spreads, it will be detected by the enemy country, and the consequences of millions of soldiers in my Datang Dynasty will be in danger! Look to the saints! ”

Xuanzong pondered for a while, nodded slowly, and said, "Your worries are reasonable. In your opinion, how should this matter be handled? ”

Yang Qing didn't hesitate: "Weichen thinks that the Holy Lord can appoint a cautious and close person, enter the weapons prison, select reliable subordinates, and set up a separate group to specialize in gunpowder development. Before that, we should try our best to improve the management system and confidentiality system to ensure that it is safe and confidential! ”

"Okay, that's it! However, this person has to think about it for a while, and after deciding on the candidate, I asked him to come to you, and prepare for you to have more snacks in the early stage. ”

"Wechen obeys!"

"Alright, let's stop here today, I'm a little tired. Yang Qing, you come to Furong Garden tomorrow afternoon, the concubine has something to look for you. Seeing that your eyes are red and swollen, you didn't rest last night, okay, rest earlier today. I'm waiting to see what kind of new army you bring out! Don't break yourself down first. Xuanzong was in a good mood and advised with a smile.

Yang Qing was moved in his heart, and bowed to the ground: "Thank you for your care!" ”

************

Walking on the wide inner city wall, Yang Qing looked at the brightly lit Huaqing Palace inside the wall, and squinted his eyes comfortably. Although it snowed heavily last night, this Huaqing Palace is still as warm as spring, like a fairyland.

"Ganting, it's much more comfortable here than Chang'an City!" It wasn't Yang Qing's turn to come out to inspect the night tonight, but somehow, although he didn't sleep all night, Yang Qing didn't feel the slightest tiredness, and maybe he was still immersed in the joy of the successful gunpowder test explosion. I couldn't sleep anyway, Yang Qing simply got up and pulled Shang Han up to the inner city wall together, and the situation of patrolling the night was fake, and watching the night view of Lishan was real.

"Yes! You can also go out for a walk, and breathe in the mountains very easily. Shang Han remembered his childhood in Nanshan, and he was quite emotional. Although the childhood in the mountains was not very happy, it was free. Instead, he entered Chang'an and couldn't go out at night. I'm big, and I'm busy, but I don't know what I've been busy with all these years.

"Hey Ganting, have you ever been in a hot spring?" Yang Qing's eyes were only staring at the hot spring pools below, not noticing Shang Han's expression, and suddenly asked with interest.

"Soaking. There are also many hot springs in Namsan that I used to visit when I was a child. Shang Han remembered the past and showed a rare smile.

Yang Qing turned back in surprise: "That's good, next time you take me and call Zhang Nan!" We can't soak here, so let's go to Nanshan to soak! Take Juan'er with you! No, the whole family goes! When the time comes, you two will go hunt rabbits and catch fish, and I'll roast them!" ”

Shang Han was obviously infected by Yang Qing's happy mood, and laughed: "I'm afraid that my uncle won't have time!" ”

"Yes! There must be! Isn't there a holiday in the year? How about we go to Nanshan for the New Year? Yang Qing was very eager, at first he just said it casually, but now imagine it for himself, it's so attractive!

"Where do you stay?" Shang Han shook his head and smiled.

"Where to stay? There's no inn or anything over there in Nanshan? Yang Qing was stunned, he hadn't thought about this.

"How can there be an inn, they are all Zhuangzi who live in their own homes. It is said that there are really many people who go to Nanshan for the New Year every year, Chang'an is too cold, and it is still warm in the mountains. Shang Han explained to Yang Qing that although he still called Qin Juan "Miss", he now naturally regarded himself as the Yang family, "Didn't our family just come to Chang'an, and we haven't had time to place Zhuangzi in Nanshan." If you want to spend the winter in Nanshan, I'm afraid you will have to do it next year. ”

Looking at Yang Qing's disappointed expression, Shang Han cautiously continued: "Grandpa Guo has a big Zhuangzi in Nanshan, and he usually goes to spend summer, but he rarely goes to ...... in the year."

Yang Qing's eyes lit up: "Say it earlier!" ”
