Otaku Engineer in Great Tang Dynasty

Cheng Yaojin has nothing to do with his son at home, Li Zexuan is thinking about how to improve the fireworks on Yunshan!

After dusk, the sky gradually dimmed. Under Lan'er's "instigation", Li Zexuan set off another set of fireworks. With the dark night sky as the background, the fireworks blasted into the sky and gave out extremely bright flames.

Lan'er was very excited. The little hands were all red, but Li Zexuan was a little dissatisfied, because the fireworks were indeed very novel to the ancients, but for him as a modern person, the colors are somewhat different. It's monotonous.

Modern fireworks are not only colorful in color, but also in various forms. When they bloom in the night sky, they will always make people dizzy! The first-generation fireworks made by Li Zexuan are just a few enhanced version of the sky cannon!

"Boom, boom~!"

"Oh~!"

There was also a burst of fireworks in the direction of West College, as well as the cheers of the students. I think the students who came here to make fireworks in the afternoon have all "contributed" to the fireworks tonight.

I just hope that Mo Zhong and the others can step up patrols at night and don't be lazy, otherwise it would be bad if fireworks cause a fire!

"Miangong! What's wrong with you? Is it dissatisfied with this firecracker?"

Han Yuxi saw that Li Zexuan's expression was wrong, she rolled her eyes and asked tentatively.

What she didn't expect was that she guessed it casually, she was really right!

"Yeah! Not satisfied!"

Li Zexuan replied happily,

"what?"

Han Yuxi was dumbfounded, and said, "Sang Gong, this firecracker is already very powerful! Concubine body and Lan'er have never seen firecrackers that can fly so high and so loud! Xiang Gong, what else are you dissatisfied with?"

Lan'er's eyes lit up, and children are sometimes very greedy, especially when it comes to play-related aspects, "Brother! Is this firecracker more fun?"

Li Zexuan chuckled, rubbing Lan'er's little head, and said, "Of course there is something more fun! In fact, my brother calls this thing a firework. According to my original idea, it should be like a flower after it explodes in the sky. It’s not just a yellow light like now!"

"Wow! This is fun! This is fun! Brother, can you make a real firework for Lan'er to play?"

When Lan'er heard it, he immediately shouted excitedly.

Han Yuxi looked incredulous, she tugged Li Zexuan's sleeve, and said: "Msang Gong, there is such a magical thing in this world?"

Li Zexuan smiled and said, "Of course! I'll make one for my husband, but I just add a few more materials to it, it's not difficult or difficult!"

In principle, it is not difficult to get the kind of fireworks he just mentioned.

"The firecrackers are just filled with these black powder, so it can hurt a certain family? It's weird!"

Around Haishi, in the teacher's dormitory of Yanhuang Academy, the room of the beard was still lit.

The bearded client sat on the stool with his hands wrapped around his chest, staring at the small group of black powder placed on the desk in front of him without blinking. At the end, he murmured incomprehensibly.

The scene in the afternoon made him angry, but after the anger dissipated and calmed down, a cold sweat suddenly appeared on the back of the paper. He was scared!

He has been a teacher since he was a child and has been practicing martial arts for decades. He has only achieved what he is today-one of the top five martial arts masters today. During his life, he was either pursuing freedom or strength!

But he chased the things of his life, but today he was almost "broken" because of a small plaything. How can this not make him both frightened and frightened?

If this development continues, will it be said that a master who has been practicing martial arts for decades is not an opponent of a child with "firecrackers"?

Isn't this a great joke in the world?

Then, what is the point of these martial arts people practicing martial arts regardless of cold or heat?

Others may not believe it, but the truth is that, a small firework, a small accident, unexpectedly made the wicked squatter in a daze, into a devil!

"Ask Shan Chang tomorrow! He is also a warrior!"

When he sat in this way, the beard still didn't get out of the magic barrier, he finally gave up and continued thinking.

"Feiji, you go to the workshop and bring me something back!"

On the morning of the second day, Li Zexuan had breakfast and then ordered Pang Feiji.

"Yes! Lord Hou!"

Pang Feiji responded, and then smiled: "Does Hou Ye still want to make firecrackers?"

Obviously, when the fireworks were set off yesterday, this product was also watching. He was still amazed at the time. He wondered why the few materials he brought back yesterday could go up to the sky and explode after Li Zexuan's tampering?

Li Zexuan glanced at him, and said in a bad mood: "You are clever! If your kid doesn't have a door on his mouth, watch me turn around and don't clean up you!"

It can be said that today, apart from him, Li Zexuan, Pang Feiji knows the method of making fireworks best. If it were not for trust, Li Zexuan would never give the gunpowder formula of fireworks to Pang Feiji.

Pang Feiji repeatedly clasped his fists and said, "Hey! Don't worry, Lord Hou, my old Pang's tight mouth can't be opened even if you use an iron rod to pry it!"

Li Zexuan was able to entrust this kind of matter to him, and Pang Feiji obviously understood the importance of it, so this guy was very excited.

"Go! What the heck?"

"Hey! The subordinates will go now!"

Pang Feiji took the new formula and left quickly.

"Oh! Mr. Zhang San early!"

As soon as he left the house, Pang Feiji almost ran into the skewer who was striding over here, and he greeted him hurriedly and politely.

Without him, the qualifications and seniority of the stunner are displayed there, but he does not respect him. Moreover, during the previous military training, the stunner had also pointed out his martial arts, which made him even more grateful.

"Hmm! Does the mountain grow?"

The bearded man frowned and said flatly.

"Yeah! Lord Hou is inside!"

Pang Feiji folded his fists and replied~www.readwn.com~Hmm! "

The beardless guest nodded, turned and walked towards the other courtyard.

"Strange, Mr. Zhang San's complexion doesn't look right! Could it be that he was internally injured by the bombing yesterday? Obediently, this firecracker is too powerful, right?"

Pang Feiji walked for a while and couldn't help muttering to himself.

"I don't want to, it is serious to do what Hou Ye confessed as soon as possible! I just don't know whether the firecrackers made by Hou Ye's new formula will be more powerful?"

Pang Feiji shook his head, muttered a few words, and walked down the mountain again.
