In the next few days, Li Beidou concentrated on researching gunpowder. He had just achieved results that day, but before he had time to experiment, the housekeeper came to report that there were guests at his door.
The guest visiting was not Li Beidou, but Li Jing. This guest was none other than Li Yifu.
Li Yi's visit was in the name of giving gifts. Carloads of gifts were delivered to the Duke's Mansion, and Li Jing went out to greet them in person.
The two held hands and laughed, like old friends they hadn't seen for many years.
When Li Yifu entered the front hall, he began to bow to Li Jing and apologize. He said frankly that he was obsessed with things and was deceived by the people below, and he unintentionally offended the fifth young master of your house, Yunyun. He looked guilty and frightened, and his attitude of admitting his mistake was very sincere.
Li Jing didn't take it seriously and smiled away his grudges.
After apologizing, Li Yifu stood up and left, and Li Jing personally sent him out.
Li Jing held Li Yifu's hand and said sincerely that since we all serve as officials in the same dynasty, some misunderstandings are inevitable, so don't worry about it, and we must keep watch and help each other in the future.
After Li Yifu left, Li Beidou appeared next to Li Jing, looked at the carriage going away and said, "Grandpa, you don't look like a good person..."
Li Jing raised his leg and kicked it, "I'm older than him, am I also an old guy?"
Li Beidou said sweetly: "Grandpa can live at least two hundred years old, and now he is a young and tender boy."
Li Jing smiled. This grandson was really sweet, but he was too bad-tempered. "Let this end your grudge with him. Don't provoke him in the future."
"Grandpa, what if he provokes me first?"
Li Jing snorted, "Then there's no need to be polite. People from Duke Wei's mansion should not be insulted lightly."
Li Beidou shook his head in disbelief, "My grandson will understand what grandpa said. If this old boy provokes me in the future, my grandson will burn his whole family down."
Li Jing showed a toothache expression, "Forget it, just pretend that I didn't say anything. When you see him from now on, you will kneel down."
After saying that, the two looked at each other and smiled.
Suddenly, Li Jing's smile turned cold, and he snorted and said, "I have come to apologize, but I still refuse to let go."
Li Beidou was confused, "Grandpa, how do you say this?"
Li Jing stroked his beard and said, "You are the one Li Yifu offended. Logically speaking, he should apologize to you. But from the beginning to the end, he didn't say a word about you, and didn't even say that he met you. It was clearly because he didn't want you." Come on, if the old guy is so rampant, he will end up sooner or later."
Li Beidou smiled and said: "It doesn't matter, it's best not to apologize to your grandson, otherwise if he becomes an enemy in the future, your grandson will be embarrassed to deal with him harshly."
Li Jing glanced at Li Beidou, seemed very satisfied, and waved his hand arrogantly, "Go away."
Not only did Li Beidou not roll away, but he grabbed Li Jing's arm and said mysteriously: "Grandpa, my grandson has made a new gadget. Grandpa, do you want to see it?"
Li Jing was pulled to his yard by Li Beidou with a confused look on his face.
Li Beidou opened the oil paper bag, took out a firecracker and stuck it on the ground, and asked his grandfather to cover his ears.
Li Jing looked at the small firecrackers with disdain on his face.
Li Beidou took out a lit incense stick and put it close to the firecracker fuse.
With a scoff, the fuse was lit, and Li Beidou turned around and ran away.
A loud bang echoed in the empty yard for a long time.
Li Jing trembled in fright and barely managed to move.
In the other courtyard, when Ah Si and others heard the loud noise, their expressions suddenly changed and they immediately rushed over regardless of their own safety.
When they arrived at the courtyard, they saw Li Jing and Li Beidou at first sight. Without saying a word, Ah Si and others drew out their swords and surrounded them, looking around with vigilant expressions.
Li Derjian and his wife heard the sound and wanted to come out to check, but they were protected by their own troops, who formed a human wall with their bodies and escorted them back to the house.
Seeing the chaos in front of him, Li Beidou was a little surprised. He didn't expect that the movement would be so loud. It seemed a bit high-profile.
Li Beidou signaled everyone not to panic, "Um...don't panic, it was me who did it just now."
Li Jing said in shock: "Beidou, just now...that loud noise...ahem, what in the world can make such a loud noise? It's like thunder in the clear sky."
"Grandpa, it's just a firecracker, no big deal."
Li Jing said excitedly: "Beidou, show me this."
Li Beidou took out a firecracker from the oil paper bag and handed it to Li Jing.
Li Jing took the firecracker and looked at it carefully.
Ah Si and other members looked in disbelief when they saw that a small firecracker could make such a loud noise.
After Li Jing finished watching the firecrackers, he stared at the small crater on the ground that was blown up by the firecrackers, his expression becoming more serious.
After a long time, Li Jing said: "Can this thing... hurt someone?"
Li Beidou nodded.
Then Li Jing seemed to have come to his senses and ordered: "Ah Si, go ahead and tell the whole government to silence. Not a word about the firecrackers will be revealed."
"promise!"
Li Jing waved his hand and drove everyone away.
Seeing everyone leaving, Li Jing grabbed Li Beidou's arm and asked eagerly: "If firecrackers are used in larger quantities and containers and are used on the battlefield, can they cause death or injury to the enemy?"
Li Beidou looked at Li Jing with a smile. He was worthy of being a general. His perspective on looking at things was indeed extraordinary and had risen to the national level.
Li Beidou said honestly: "Of course you can, and you can kill a hundred people with one thing."
Even though Li Jing was mentally prepared, he was still frightened by what Li Beidou said.
Li Jing said with a trembling voice: "This thing will be of great use to the Tang Dynasty. The secret recipe must not be leaked." He spoke excitedly while spinning around.
Suddenly he thought of something again and said seriously to Li Beidou: "No, this secret recipe cannot be kept in your hands. It must be reported to the emperor immediately."
"Grandpa, don't worry. This thing is called gunpowder. It can change the world. My grandson understands that ordinary people are not guilty of carrying a jade. My grandson originally wanted to give the secret recipe to the emperor."
Li Jing patted Li Beidou on the shoulder happily, "I will enter the palace to meet the Holy Spirit."
When Li Jinglin went out, he personally ordered that the door should be closed to thank guests, and that no one should be allowed in or out until he came back.
…
Tai Chi Palace.
Li Shimin asked with a serious expression: "Can the thing called firecrackers created by Mr. Li really be capable of destroying rocks and solids?"
Li Jing replied respectfully: "I saw it with my own eyes. After the firecrackers exploded, a piece of soil on the ground was overturned, leaving a small pit. The firecrackers were no more than the size of a little finger. If the amount and container of the firecrackers were increased, I would think that I would be too big." The King of the Tang Dynasty will definitely add an indestructible weapon. I think this thing is more magical than a strong bow."
Li Shimin's eyes lit up and he couldn't help but lean forward, "Does Beidou have an explanation?"
Li Jing said slowly: "My grandson said it himself, if this thing is used to attack a city, it will be invincible; if it is used in a flat ground battle, it can destroy everything and be invincible."
Li Shimin was shocked and his breathing became rapid, "Is this true? Beidou actually made such a sharp weapon."
"I don't dare to say anything false. I have ordered the whole government to close the door to thank guests. No one is allowed to come in or out, and no word is allowed to be leaked to outsiders."
Li Shimin stood up glumly, his face flushed and his chest heaving, "Come here, summon County Prince Li to the palace to perform a duel."
Before the eunuch could pass the order, Li Shimin hurriedly said: "No, I have to go there in person."
