Otaku Engineer in Great Tang Dynasty

? Just after lunch, Lan'er urged him impatiently.

"Brother! Quickly let off the firecrackers, Laner wants to watch the firecrackers!"

The little girl was a little tired of visiting the academy with her grandpa and grandmother these past two days. After all, she had been playing in the academy before, and the freshness had already gone, so she came back alone at noon.

During the meal, she heard Han Yuxi say that Li Zexuan had made a big baby like firecrackers in the morning. The little girl was immediately excited. If Li Zexuan hadn't stared at her, she would have to go play with fireworks if she didn't even want to eat!

It is the nature of children to play, whether it is in modern times or in ancient times, it is mostly the same. Especially for things like fireworks and firecrackers, children like to play more!

Li Zexuan in his previous life used to play firecrackers every Chinese New Year until he was in high school!

"Okay! Let it go! But Lan'er, you have to stand farther!"

Li Zexuan patted Lan'er's head, and said in love.

The main reason for the little girl to stand further is that he has no confidence in the fireworks he made. After all, he had only played this thing in his previous life, but he had not done it. In the morning, he only used the memory of dismantling a firework in his previous life and slowly explored it by himself. He just made a test product. Whether it can be launched or whether it will explode on the spot, he has no spectrum in his heart!

"Hmm! Lan'er must stand far away!"

In order to watch Li Zexuan set off firecrackers, Lan'er was willing to agree to anything!

"That's fine! You go to the front yard first, and my brother will go back to the back yard to get things!"

Li Zexuan got up and said.

Of course, this kind of dangerous experiment should be as far away as possible from home, otherwise he experimented with fireworks in the backyard, if the house exploded, he would be very distressed!

"Hmm!"

Lan'er responded, and then took Han Yuxi's hand and said, "Sister Yuxi, can you go too? Lan'er is scared alone!"

"Puff!"

Li Zexuan, who had just walked to the door of the backyard, almost fell to the ground: Are you afraid? If you little girl is scared, she won't cry and shout to play with firecrackers!

"Okay! Then I'll go with Lan'er!"

Han Yuxi nodded and agreed.

Actually...she herself really wanted to go, but when she thought that she was married, she would be out of dignity to see these children's gadgets. Now that Lan'er invited such an invitation, she just happened to be in good shape!

……………………………

"Lady, Lan'er, stand a little further back!"

"Huh? Brother! It's all this far, so stand back?"

"Well! Not enough! A little further away!"

In front of Yunshan Courtyard, Li Zexuan carried a plate of test fireworks. This test product was connected to nine fireworks with lead wires. The three-by-three layout made its chassis very stable.

Li Zexuan took a shovel and dug a shallow pit, buried one-fifth of the firework in the mound to ensure that it would not fall over during the setting off, he repeatedly urged Lan'er and Han Yuxi to retreat.

To be honest, Li Zexuan didn’t pay attention to the igniting powder in the fireworks, but for his wife and sister, it was completely different. In case of an explosion, they would be burned or burned. Disfigurement is possible!

"Brother, this is all right?"

Lan'er crossed Xiaoman's waist and yelled at Li Zexuan impatiently. She always felt that Li Zexuan had made a big fuss. Even if this "firecracker" is more powerful than the firecrackers she used to play, it won't let her. They stand so far away! The little girl wondered if she could hear the "firecrackers" in a while.

"Yes! Lan'er remember to cover your ears!"

After checking the distance visually, Li Zexuan shouted at his sister.

Lan'er curled his lips, unmoved.

Li Zexuan smiled, little girl, you still don't believe in evil, and you will regret it later!

At the moment, he stopped talking nonsense, and stretched the firework next to the fuse of the fireworks.

This fuse is made with a small amount of gunpowder wrapped in straw paper that is used as a fire folder. It is easy to ignite. As soon as the burning fire fuse in Li Zexuan's hand touched the fuse, a spark and a burst of "babble" appeared. The sound.

In this case, it is not the time to pretend to be forced. Li Zexuan saw that the fuse had been ignited and hurriedly pulled out. Although he was strong in martial arts and was not afraid of such a small explosion, he was not afraid of returning, and he was not guilty of pretending to be unnecessary. It was embarrassing, then it was not a pretense, but a fool!

"Boom!"

Over the quiet Yunshan, there was a loud and deafening noise. There are not many tall buildings in this era, so this loud noise can always be heard from far away.

After a loud noise, it didn't stop. The next loud noise followed. By this time Lan'er was already scared and screamed again and again. The little girl reacted at this moment, and quickly covered her ears with her little hand, and then became angry. Glancing at Li Zexuan, it seemed to mean, why didn't you say that the "firecracker" was so loud?

Li Zexuan didn't notice the anger and resentful gaze of his little sister. He was looking up at the results of his hard morning experiment!

"Tsk tusk, the height is ok! It's just that the sound is too loud, you have to reduce the amount of ignition powder, and the flame is not bright enough, maybe because it is daytime, you can try again at night!"

Li Zexuan raised his head and muttered softly.

"Brother! This firecracker is amazing! Do you still have it?"

Nine rounds of fireworks were quickly finished. It was the first time that Lan'er saw this kind of fireworks that could soar into the sky. Although she was frightened to death because she was unprepared, she got used to it later. , The fear in my heart was immediately replaced by excitement.

"Hey! Laner, weren't you scared just now?"

Li Zexuan said with a smile.

Lan'er Da囧, just about to say something, a few people heard a sound of breaking through the air not far away, and then saw a bearded sweating and an old man with gray beard rushing here!

It is Mo Zhong and the bearded guy!

"Shanchang, I waited until I heard nine loud noises coming from here, what happened?"

Mo Zhong stopped in front of Li Zexuan~www.readwn.com~ asked nervously.

Li Zexuan was taken aback for a moment, and then a little embarrassed: "Nothing happened, but I just set off the firecrackers!"

"Firecrackers?"

Now it's Mo Zhong's turn to be stunned. He is a dignified Mo family giant, what new thing hasn't he seen? Why haven't you seen any firecrackers that can be so loud?

At this moment, the bearded man saw the fireworks tube that was just finished in the distance. He walked over and took a closer look, and said in surprise: "This is the firecracker you said, the head of the mountain? Why is it made of paper?"

"Wow~! What! What was ringing just now~?"

But Cheng Chu held a football silently, and led a group of students rushing towards this side, screaming while running.
