A person who takes revenge overnight, and has such a nickname, when he shows an open-minded side, everyone's eyes are weird.

His Majesty Li Er gritted his teeth even more, and slapped his right hand several times, and finally probably considering that the time was wrong, he only snorted angrily, and then turned to leave.

In this way, after the sacrifice, a group of princes and princesses found a place to rest by themselves, and the younger ones rested with their mothers.

By the time Li Chengqian returned to the 'Lanruo Temple', it was already early in the morning of the first day of the first month of the third year of Zhenguan.

With the help of the maid, it took a long time for the donkey to take off the crown dress on his body, and Li Chengqian, who changed into pure cotton pajamas, plunged into the warm quilt, and almost instantly, he fell asleep completely unconscious.

The cotton deseeding technology has already been solved under the strong research of the Ministry of Industry, and all the quilts used in the palace in winter have been replaced with quilts, and even the clothes are basically cotton clothes with cotton.

However, because the cotton production of Datang is too low, cotton products are still not popularized among the people, and even if Wei Zheng does not stop it, in order to ensure the supply of the army, cotton will almost be listed as a prohibited product and banned from civilian use.

However, these have nothing to do with Li Chengqian, as the first person who invented the quilt, he will not care how this thing is used, just as the first person who invented the electric light will not care whether people use electric lights for lighting or heating.

The sun shadow was slanting westward, Li Chengqian got up from the kang in a daze, rubbed his already hungry stomach, estimated the time through the somewhat dim window paper, and found depressedly that this sleep seemed to be reversed.

"Your Highness, are you awake?" The maid waiting in the room asked softly.

"What time is it?" Rubbing his eyes, Li Chengqian yawned big.

"It's the end of the hour." After the maid answered, she brought down the hot water from the stove in the room, and then some cold water, waited for Li Chengqian to wash his face, and asked at the same time, "Your Highness, do you want to pass the meal?" ”

"Pass it on, and call Wang Chenghu in."

"Whoa!" The maid agreed and withdrew, leaving Li Chengqian alone in the room to figure out how to pass the time for a while.

"Your Highness, are you awake?" Wang Chenghu walked in from the outside with a shiny bald head and a cold air.

Li Chengqian shivered from the cold wind, shivered and asked, "Wake up, do you know where the 'firecrackers' are placed?" It's the new batch. ”

Wang Chenghu recalled for a moment and said: "It should be in the Department of Treasures, and the minister remembers that it was sent there." ”

"Halfway through the pitch, let's have a good time tonight." Li Chengqian's eyes were shining, especially setting off a firecracker in the future is within the scope of control, and now that he is in Datang, I guess my Dachengguan should not travel through time and space to catch himself because of this little thing.

After Wang Chenghu left, Li Chenghao hastily ate the meal, and it was completely dark at this time, which was the best time to set off firecrackers.

After waiting for a while, just when he was a little impatient, Wang Chenghu took a big cart, which was filled with bamboo tubes more than three feet long and thick bowls.

Fundamentally speaking, these things are not actually firecrackers, and Li Chengqian did not intend to use them as firecrackers when he made them.

A bamboo pipe that has been opened, one end is sealed with something, and a gunpowder bag with a small amount is inside, and on the upper layer of the gunpowder bag, another gunpowder bag weighing about a pound is placed. When the exposed fuse is ignited, the first layer of gunpowder packs will burst first, and under the restraint of the bamboo pipe, the impact force that pours out of nowhere will push the upper powder packets into the sky.

What is this kind of thing? If you put its opening in the sky, most people will think of ceremonial flowers, which must have been placed like this in the 90s.

(At that time, the ceremonial flower was a bowl-sized round ball, which was lit and put into a cardboard tube with many loops, and then ...... The flowers will go to heaven)

But what if it's flat? A simple bazooka? Tie a lot of roots together? Multiple rocket launchers? In short, no matter what it looks like, when it was first made, Li Chengqian didn't treat it as a firecracker in the normal sense.

But now Li Chengqian is too boring, and after thinking about it, only this thing is more interesting, so he .......

"Your Highness, it's already done." After the preparations were made, Wang Chenghu returned to Li Chengqian with an excited face.

When he had just made the first batch of 'firecrackers', he had played with them a few times, and the huge sound and powerful destructive power made him a loyal fan of 'firecrackers' almost instantly.

However, at that time, because this thing was too troublesome to make, Li Chengqian quickly stopped him from continuing to play, which Lao Wang has always been worried about.

Now that the opportunity has come, His Royal Highness the Crown Prince has proposed such a large number at one time, and this time it can finally be enjoyed.

"If you get it right, you can put it away, so hard that you still need me to teach you how to put it?"

Out of the heart of showing off, Li Chengqian despises those genuine firecrackers that make a popping sound when burning bamboo tubes, so he wants to make a big one, completely suppress those guys who set off firecrackers, and let them know what real firecrackers are.

When Li Chengqian crossed over, the phrase 'if you don't die, you won't die' was not popular, so when Li Er and the eldest grandson, who were wearing pajamas and fur furs, appeared in front of him, Ya was happily admiring his masterpiece.

"Rebel, what the hell are you doing!" Seeing that Li Chengqian lit the fuse of a bamboo tube, and then there were two explosions, one small and one large, Li Er finally couldn't hold back his anger and jumped to his feet and roared.

"Uh~, father, mother, why are you here?" Li Chengqian blinked innocently, very puzzled by the old man's ambience.

"Why can't Lao Tzu come, Lao Tzu will come to kill you as a rebel." Li Er was already angry, he didn't care about the cold, his shoulders shook and his fur fell to the ground, he rushed to Li Chengqian in three steps and two steps, grabbed him and pressed him on his legs, and began to fan his buttocks, deaf to Li Chengqian's screams like killing pigs.

"Slap" a slap: "Lao Tzu beat you to death and let you steal Lao Tzu's things." ”

"Slap" slapped again: "Why are we here, the winter thunder, do you know how much trouble it caused." ”

"Smack" and slapped again: "Lao Tzu asked you to pretend to be innocent." ”

"Papapa" The sound of a series of slaps on the buttocks: "Lao Tzu let you: there is wine today and drunk today, and tomorrow will be sad tomorrow." ”
