Datang Hotel: The Leisurely Life of a Chef Dad

After teaching some knowledge to Li Lizhi, Liu Xuan can use it unscrupulously.

There are so many people who take the blame in this world, and the best scapegoat is Li Shimin's own daughter.

"Liu Xuan, what kind of knowledge is that?"

Li Shu has liked to wield spears and sticks since she was a child, and is familiar with military books. When she heard Liu Xuan mention that this knowledge is very big and she can't grasp it, she subconsciously thought of the first time she picked up a wooden spear when she was a child. At that time, the wooden spear was very thick, and her little hands were indeed not able to hold it.

Li Shimin looked at Li Shu's appearance and smiled from ear to ear, and Empress Changsun was also very pleased.

Li Shu's biological mother was even more tearful. A child chooses what she wants to do, which means that she has begun to grow up.

Now facing this problem again, Li Shu did not hesitate at all. After asking this question, she hurriedly said: "Don't worry, no matter how much hardship, I can bear it."

Liu Xuan sighed: "Miss Li, this knowledge requires talent, but the basics can be learned."

Mathematics and physics both require talent.

Today, Cheng Chuxia left after finishing his homework. Liu Xuan was not wrong. Among the people in the Tang Dynasty, Cheng Chuxia was the hidden math genius. His sensitivity to numbers seemed to be innate.

This was also an unexpected gain after crossing.

Physics, this kind of thing, seems to have appeared.

"I have a good talent. I can lift a 100-jin steel gun since I was a child!" Li Shu proudly raised her chest, which had not yet fully developed, and her eyes were full of the sharpness that a girl of this age should have.

Li Lizhi also cheered on the side: "Yes, they are all fathers and sons fighting in the battlefield. We three sisters can definitely learn this knowledge!"

Liu Xuan nodded: "Since you think you can withstand it, then try it."

"Come to class tomorrow."

Hearing this, Li Lizhi was ecstatic and cheered. What awaited them would be endless troubles of seeking but not getting, or the sea of ​​stars, it is still unknown.

Liu Xuan only knew that several huge firecrackers had been made, waiting for the first cannon to sound in the whole Chang'an in the morning tomorrow.

It is no longer a small thing like firecrackers, but a real firecracker, something made of gunpowder.

The three sisters didn't know what was going on today, but they had to eat stinky tofu. They ate until their stomachs were full. Now they were full and pulled Yaya and Dazhuang, who had just bought new clothes, to play with each other.

Yaya excitedly took out the candy: "Sister, Yaya has her own candy shop. Welcome to buy candy."

Dazhuang had a silly smile on his face. He knew that the young master said that he and Yaya each had half of the candy shop.

"Hehe, welcome, come and buy more candy..."

Li Lizhi and the other two were amused and fell backwards. They ate candy in their mouths. After wrapping gifts for Yaya and Dazhuang, they were ready to leave.

At this time, a red glow suddenly appeared on the horizon, and snowflakes floated in the sky.

At the edge of the red glow, there is a black line, swallowing up the last ray of light in the sky. In the clouds, the struggling light is like a candle in the wind. The small flame keeps flickering and struggling, trying to break free from the endless and deep sea of ​​clouds, but gradually it is powerless and disappears in the sky.

At this time, Chang'an in the Tang Dynasty was peaceful and joyful. Red lanterns were hung on the sides of the main roads of the Tang Dynasty. The lanterns of the Tang Dynasty were a bit flat and not small, highlighting a brilliant atmosphere. This is completely different from the red and white cross-shaped lanterns that Liu Xuan saw on a so-called Tang Dynasty-style street in the future, which looked like Japanese gourds.

It was the New Year, and Liu Xuan was a little sulky again.

Men always have some helping complexes and hate iron for not being able to make steel.

Looking at the land under his feet, it seems to be no different from that in the future, but why do some people in the future have shit in their heads?

After hanging two big red lanterns at the door by himself, Liu Xuan forgot some unpleasant things and was satisfied.

"Liu Renyuan, are the firecrackers ready?"

Liu Renyuan came out from a corner, sweating all over, as if he had just been fished out of the water.

"My Lord, it's almost done, it's just that the hole is a bit stuffy, a box is ready."

Liu Xuan nodded: "Put it in a cool and ventilated place, don't get close to the fire."

Liu Renyuan didn't know why he had to do this, but he had to do it. If the Lord said it was dangerous, it must be dangerous.

Liu Xuan wanted to hide this thing, but now it has started to develop. Since several factories have shown their fangs, they can't hide it.

Even if you are the Marquis of Lantian in the Tang Dynasty, so what?

Without the blessing of powerful military force, others will still touch you.

Didn't you see that some Chang'an Supervisory Censors disappeared after inspecting the local area? It is not enough to have the title of official. The maintenance of this title depends either on connections or on force.

One sulfur, two nitrate, three charcoal, add some sugar, big Ivan.

Liu Xuan chanted the formula and asked Liu Renyuan to put those things in the secret room of the Marquis' Mansion. Liu Xuan spent an afternoon filling the bamboo tubes with Da Zhuang. The last step was to seal and insert the fuse, and then let Liu Renyuan complete it.

At most, there should be two large boxes of firecrackers. This kind of firecracker is obviously different from those in later generations. It is obviously a bit crude, but it doesn't matter. As long as the noise is loud enough, everything is fine.

When the night of New Year's Eve came, thousands of lights were lit in Chang'an.

Countless people lit firecrackers, that is, burning bamboo with fire, making crackling sounds, to drive away mountain ghosts and plague gods, and beat the monster Nian back to its original form.

Liu Xuan took out ten firecrackers and placed them in the courtyard.

Liu Renyuan and Xue Rengui had not yet realized what was different about this thing, and they were grinning and waiting for the Marquis to give orders.

"After lighting it in a while, you have to run away quickly."

Liu Xuan decided to try it on New Year's Eve. After all, it was the first time for him to make a firecracker.

Almost everyone in later generations knew how to make this thing, but no one made it.

When he arrived in the Tang Dynasty, Liu Xuan said he would try it himself.

The gunpowder in the firecracker is divided into two parts. The lower gunpowder is used for boosting, and the upper one is for explosion.

Seeing that it was getting late, Liu Xuan said with a smile: "Liu Renyuan, you go and try it?"

Liu Renyuan scratched his head and looked at Liu Xuan cautiously: "My Lord, is this okay?"

Liu Xuan patted Liu Renyuan on the shoulder: "Believe me, when have I ever lied to you?"

Liu Renyuan was skeptical, holding a thick incense stick in his hand, and approached carefully, then started to light it from the edge.

Chichichichi... The moment the fuse was lit, Liu Renyuan instinctively felt the danger and ran away.
