"Young Master." When Bafang saw Meng Changqing coming in, he immediately stood up from behind the desk, and went to help her hang up her clothes with a pen, "When do I have to copy so many names?" Otherwise, let the money be copied. ”

"No, he has enough patience, there is no need to grind."

Eight sides quibbled: "I have enough patience." ”

Meng Changqing took off the dusty padded jacket on the shelf, "Hurry up and copy it, I'll use it tomorrow." ”

"Where are you going?"

"Go to my mother's for soup."

Meng Changqing was about to go to Wen's side with a padded jacket, and before he had walked a few steps out of the hole, he heard the sound of horses' hooves getting closer and closer not far away.

The comer rode alone and went straight to Meng Changqing, but when he was about to approach, he was stopped by the Royal Forest Army.

"Alas, I'm looking for you Lord Meng, we are old friends." It was Chen Xingqi who was pulled off the horse.

When he saw who the people around him were, he was overjoyed, "Second Brother Wang!" I said why haven't I seen you home for a long time, it turned out that I came here with Changqing! ”

Wang Xun dodged the hand he was about to hook his shoulders and back, "Don't hook up." ”

Chen Xingqi was very curious about him, "Second brother, are you being excluded in the palace?" How did you keep up with Meng Changqing? He's got a lot of bad ideas, so you have to be careful...... Hey, evergreen! I'm relieved to see you standing with your hands and feet. ”

Meng Changqing stood next to them with a padded jacket, "What's the matter with you?" ”

"I'm coming to see you!" Chen Xingqi left Wang Xun and strode in front of Meng Changqing, "I've been really sad in the past few days, and I've been inquiring about the news of Beishan County when I returned to the camp, I heard that you're fine, Beishan County is also guarded, and I can eat."

I finally took a leave of absence today, so I immediately came to see you, how are you? Okay? ”

"Fortunately, since you came, you will come to my yamen to sit down, it just so happens that I have something to look for you." Meng Changqing said to Wang Xun again, "Brother Wang, please tell my mother that I have a guest to entertain, and I will go later." ”

"Yes."

"Let's go and have a look at your yamen." Chen Xingqi's mouth was the same as borrowing, "I didn't look at your Beishan County carefully when I left in a hurry last time, huh?" Where are you going? ”

Meng Changqing stood on the steps and replied to him, "County government." ”

Chen Xingqi followed behind, cautiously opened the door curtain, and glanced around the small pothole, "I thought you were going to fix me, but it was really where you live!" ”

"Come in and sit."

Bafang wanted to get out of the way, but Meng Changqing held him down, "You write yours." ”

Meng Changqing moved two small stools, and the two sat down against the charcoal basin.

"What the hell are you looking for me?" Chen Xingqi hesitantly took the tea bowl handed by Meng Changqing, "Look, isn't it a good thing for you to do this?" ”

"About the Heaven-Shaking Thunder."

At the mention of the earth-shattering thunder, Chen Xingqi immediately became serious, "Is the explosion rate too low?" ”

"No, I'm trying to give you more than one direction to study." Meng Changqing said, "I think you have already heard of how the cavalry of the Yan Army broke the power of the earth-shaking thunder.

Although Dazhou has been occupied by Yan for decades, it is not because the people of Dazhou have their hearts towards Yan, but because the imperial court can't hold it, so it is occupied by Yan.

In the final analysis, the people of Dazhou are the people of Daliang.

How can you bear to see them blown to pieces by the earth-shattering thunder? ”

Chen Xingqi said: "Although I didn't see the scene of that day, I just heard the soldiers talk about it, and I was about to explode." ”

"So, can you change the mine to a grenade, or...... Cannon. ”

"What?" Chen Xingqi intuitively felt that he must be interested in what he said, and his eyes couldn't help but widen, "You tell me carefully, what is a landmine, what is a grenade." ”

"The earth-shattering thunder used by the girder now begins to explode after being touched by a heavy object, this is what I call a mine, as for the grenade, have you ever let off firecrackers?"

"Naturally, let it go."

Meng Changqing said: "The principle of grenades is like firecrackers, leaving a fuse, and it will explode after a period of time after ignition, so that our soldiers can take advantage of this time to throw the grenade out." ”

"Isn't this going back?" Chen Xingqi said, "There was this practice earlier, but it was really unsafe, and if we were not careful, we would kill our soldiers, and it could not be applied on the battlefield at all. ”

"It's a matter of quality, not direction." Meng Changqing said, "Obviously, we are now using the method of earth-shaking thunder, which can be easily cracked by the Yan army.

If the earth-shattering thunder can be thrown, the time for laying mines will be saved, and your artillery army will not be an army that is only useful when laying ambushes before the war.

Plus the trebuchet, put the earth-shaking thunder in the trebuchet and throw it out......"

Chen Xingqi slapped his thigh happily, "I knew that we were confidants!" I thought so, but my father called me crazy! ”

"In order to do this, the earth-shaking thunder must be stable enough." Meng Changqing poured cold water on him.

"Indeed, that's where it gets tough! I changed the ratio of gunpowder a few times, and found that the more powerful it was, the easier it was to explode. ”

Meng Changqing said: "If there is really no way, for the sake of its controllability on the battlefield, there is no need to blindly pursue power. ”

"I can only try, try different materials and gunpowder ratios." Chen Xingqi said, "When do you have time to come to my place, I have made a lot of records, let's discuss and discuss together." ”

"I'm not as good as you in this regard, you still have to discuss it with people within the artillery army." Speaking of this, Meng Changqing's expression suddenly became serious, "You are now in charge of the artillery army?" ”

"How is that possible? I'm only responsible for changing the recipe. ”

"This is the border gate." Meng Changqing reminded him, "Once the formula you changed leaks out, you are collaborating with the enemy and treason, isn't it."

You must be on guard yourself, and those who follow you must know where they come from, and what you write must be kept. ”

"Good, good!" Chen Xingqi arched his hand, "Thank you for reminding me." He couldn't sit still, "I have to go back, you can remember to visit me in the barracks when you have time." ”

"Let's go, I'll send you." Meng Changqing rode him past the old site of the city wall, and watched him enter Yangmen County before turning back.

"Master, let's go back too."

On this day, the battlefield outside the city walls was cleared.

It was also time for the people recruited from the counties to go back, except for those who were seriously injured, who were allowed to stay and recuperate, and the rest of the people, Meng Changqing, sent a small bag of millet to them, and personally sent them to Yangmen County.

The people went home happily, and this experience in Beishan County was enough for them to talk for several years.

In Qianzengzhuang below Liangzhou, when the people who went out to work arrived at home, the village was very lively.

Mrs. Zeng walked around the crowd three times, and was stunned that she didn't see her two sons, but Qian Baoshan stopped her, "Auntie, don't look for it, they haven't come back yet." ”

"Why didn't you come back? Didn't you say it was over? Mrs. Zeng was afraid that the other party would spit out bad news, and she was ready to faint at any time.

"It's not a big deal, just a few days at night."

Sister Wanjin, who was good friends with Meizi, said: "Auntie, this time your house is going to be beautiful, the boss killed three Yan soldiers, and the guards of their group persuaded him to join the army." ”
