Ye Mao left in the morning. In the afternoon, the imperial edict given to Li Xin by the court also arrived. Li Xin was appointed General Dingbei and led the four Zhechong Prefectures that had set out earlier to rush to assist the battlefield in the northern border.

The imperial edict was sent to the Jing'an Marquis Mansion by Xiao Zheng himself, and he clearly stated that he ordered Li Xin to leave Beijing as soon as possible and to urgently rescue Jimen Pass.

Li Xin knelt on the ground. After listening to the imperial edict, he stood up and patted the soil on his knees. He reached out and took the imperial edict from Xiao Zheng. After Xiao Zheng handed the imperial edict to Li Xin, he smiled and said, "Trial tutor, Your Majesty instructed me to let me take something from you and go back."

Marquis Jing'an nodded with a smile: "This is natural. I am a person who keeps my word. If I say it, I will definitely give it."

He glanced at the dozen red-clothed inner guards following Xiao Zheng, and said with a smile: "The thing is in my room, Eunuch Xiao will go with me to pick it up?"

Xiao Zheng nodded and said, "I'm sorry, the tutor."

"Your Majesty said that after you get the things, the Grand Tutor can go out to Beijing at any time."

Li Xin walked in front with his hands behind his back and led Xiao Zheng into the backyard of the Jing'an Marquis Mansion. He walked all the way to the gate of the small courtyard where he lived. Xiao Zheng stopped at the door and did not dare to step in.

"I am waiting for the tutor here."

This yard is not only Li Xin’s residence, but also the Ninth Princess’ residence. The eunuch is a slave of the Tian family. Even if the Ninth Princess is not here, he dare not enter the yard.

Li Xin nodded and walked into the yard. Not long after, he took out a wooden box and handed it to Xiao Zheng. Xiao Zheng opened the box and looked at it. There were two rows of twelve pots neatly contained in the box, each of which was the size of an adult fist. The eunuch of the eunuch took a deep breath and said, "Tao Fu, is this thing a heavenly thunder?"

"Of course."

Mr. Li's face was calm and said, "The backyard of my house is also very spacious. Eunuch Xiao doesn't believe it, so you can click one here and try it."

Xiao Zheng did not refuse. He lowered his head and said, "It's really a big deal that I don't believe in the Grand Tutor, and I offended it."

He reached out and waved, and several inner guards in red came over and helped Xiao Zheng hold the box. He took out a thunder from the box himself, took a deep breath, walked to an open space in the backyard of the Hou Mansion, and then took out the fire sack from his arms.

At this time, Li Xin, who was more than ten steps away from him, smiled and said, "Eunuch Xiao, if this thing explodes, you won't regret it and arrest me?"

Xiao Zheng stopped his movements, looked back at Li Xin, and shook his head and said, "Tao Fu, what I have brought is an imperial edict, which is drawn up by the Shangshu Desk, and His Majesty personally added the seal. After several prime ministers have read the public announcement of the court, the court cannot change its orders every day, you are too worried."

As he said that, he turned around and took out the fire cube, blew out the sparks, lit the fire-driven paper on the clay pot, and then ran away quickly and ran to a distance of seven or eight steps further away than Li Xin.

The pottery burst open with a deafening sound.

The pottery pieces splattered everywhere, and there was a piece of pottery pieces, but unfortunately it passed through an inner guard's face, and a long bloody mouth was drawn.

Xiao Zheng looked at Bai Yan in the yard of the Jing'an Marquis Mansion, nodded with satisfaction, turned to look at Li Xin, and said hesitantly: "Tao Fu, can the thunder in your box explode? "

There are twelve thunders in the box. If only one of them can be blown up, the emperor will definitely think that Xiao Zheng and Li Xin collude with each other, and that his heart will be in danger if they are cut alive!

Li Xin smiled indifferently: "There are more than ten here. If Eunuch Xiao is worried, why not click another one?"

Xiao Zheng was a little moved when he heard this, but the one he had just taken was indeed casually, and he didn't have much doubt. He shook his head and said, "Then I will bring these treasures into the palace to hand in the imperial decree. It's late now. You think you want to leave Beijing, so it's better to leave Beijing early tomorrow morning."

Li Xin smiled and said, "It's not a big deal between the left and right. As my father-in-law said, I will leave Beijing and head north tomorrow morning."

At this time, I hurriedly left the capital, but I felt guilty. Anyway, the decision-making power was in the hands of the emperor, so I was not as good as a bachelor and calm.

Xiao Zheng sighed, bowed his head to Li Xin, and said in a deep voice: "Tao Fu, please take care of yourself."

He was a manager in the secret residence of the Wei Palace. More than ten years ago, when Li Xin first entered the Wei Palace, he worked in the Wei Palace. Over the years, he has seen the ups and downs of the capital and the ups and downs of Li Xin. In Xiao Zheng's eyes, Li Xin is a very respectable person no matter what.

Li Xin also nodded at Xiao Zhenghan.

"Eunuch Xiao also takes care of himself."

The inner court is more harsh than the court. Although sitting in the position of the eunuch of the inner court, it is very glorious, but it is possible to die at any time. Li Xin and Xiao Zheng are old friends for many years. Before leaving, they say to each other and take care of each other, and it is not in vain to know each other for many years.

……………………

The next morning, Li Xin only brought a few followers from the Marquis' Mansion in Jing'an, then set out from the gate of the Marquis' Mansion, and after leaving Yonglefang, he rushed to the east gate of the capital.

Along the way, Li Xin still noticed that many people were following him secretly, but the situation has been like this in recent years. He was no longer surprised and went straight to the gate of Dongmen City.

He has been getting up early for so many years. When he arrived at the East Gate, the sun had just risen, and an acquaintance in plain clothes had already been waiting at the East Gate. When he saw Li Xin arrive, he stepped forward to stop Li Xin's horse and bowed respectfully: "Trial tutor, Your Majesty said he would come to deliver it to you in person, but the carriage has not arrived yet. Please wait a moment."

It is Xiao Huai, the young eunuch.

Li Xin smiled.

Sure enough, not everyone can get up every day before dawn like himself. His Majesty the emperor in the palace can't get up in the morning.

In fact, because the emperor was young, he had been eating the martyrdom for the past two years and was a little uncontrollable in sexual intercourse. In the days except for the Grand Court, he often slept until noon and got up before dawn. It was really difficult for him to do so.

Li Xin waited at the East City Gate for an hour before a lilac carriage slowly drove out from the city gate. Li Xin recognized Xiao Zheng, who was driving, turned over and dismounted, walked to the carriage, bowed slightly, and bowed, "I... I have seen Your Majesty."

The curtain of the purple carriage was lifted in a corner, and the young emperor came out of the carriage with two dark circles. He looked up and down at Li Xin and sighed: "The teacher got up so early."

Li Xin smiled and said, "It seems that His Majesty slept very late yesterday."

Yesterday, the emperor got the thunder he was thinking about, so he naturally had to try it out, and most of the time, he would be so excited that he couldn't fall asleep.

But what he didn't know was that the thunder that Li Xin gave him was actually a very basic version.

Gunpowder was made in Qiyuan, Qiyang County, when Li Xin returned home in the first year of Taikang, and it took half a year to repair his mother's tomb. Although the things he made were able to explode at that time, they were definitely not golden ratios. Later, Lin Hu brought dozens of people and according to Li Xin's wishes, he silently explored Qiyang for several years and improved several versions.

Moreover, in recent years, the Southwest has been making gunpowder, and the ratio of various ingredients is more accurate and powerful.

No matter how powerful the craftsmen in the court were, it might take two years to make this version of gunpowder according to their interpretation.

It took Li Xin ten years to redesign these gunpowders. It took the imperial court at least three to five years to achieve this level.

More importantly, Li Xin came from another world. He knew clearly what gunpowder was and could easily give the direction of development. No matter how powerful the skilled craftsmen in the capital were, they had never seen the scenery ahead, and it would be amazing to be able to imitate it.

Emperor Yuan Zhao yawned a little tired, then bowed to Li Xin: "Absolutely, I wouldn't let the teacher go out of the capital, but the teacher treated me sincerely yesterday, so I can't be a villain anymore."
