Otaku Engineer in Great Tang Dynasty Chapter 1126: Trial production of fireworks!

? "Feiji, go get me some of these materials!"

After sending Li Gang away, Li Zexuan wrote and drew in the study for a while, then took out a list of materials and ordered Pang Feiji.

Pang Feiji didn't even look at it, so he took it and said, "Yes, Lord Hou!"

After that, he turned and went out.

Li Zexuan hurriedly stopped him, and said with a stern look: "You keep this list for Benhou. If it is lost or seen by someone, you won't be able to hold it up! You know?" /

Pang Feiji straightened up subconsciously, and solemnly said: "Understood! Lord Hou! His subordinates will protect the secrets!"

Walking out of the other courtyard, he took out the list of materials that Li Zexuan gave him from his arms, and he was a little dumbfounded, "This! What...what does Hou Ye want these things for? Do you keep them for the New Year?"

Previously, Li Zexuan asked Li Gang to write the couplet. Although Pang Feiji was not at the scene, he guessed that Li Zexuan was preparing for the New Year. But what does the items on the list have to do with the New Year?

"Forget it! No matter! I just need to find these things for Master Hou, and make sure that this list is not seen by others!"

Pang Feiji scratched his head and couldn't understand it. In the end, he put the list carefully in his arms and walked down the mountain.

After giving instructions to Pang Feiji, Li Zexuan returned to the study and continued to edit the book.

Actually, he had compiled some of the textbooks for the second semester of the college a few months ago. After so many days of retreat, in general, basically the textbooks of the second semester are almost written. Now he The main job is proofreading.

The house is quiet, only him and the two little maids. Han Yuxi went to Chang'an in the morning, while the others accompanied Ye Guozhong and Mrs. Ye to tour the academy.

Yes, this group of people has been walking around the academy for several days, but they haven’t gotten too tired of it. Li Zexuan sometimes doesn’t understand. Isn’t it just a pile of reinforced concrete buildings? Is it that attractive?

This product is purely standing and talking. He didn't want to think about it. Ye Guozhong and Old Lady Ye were both natives of the Tang Dynasty. Wouldn't it be fresh to see the tall concrete buildings? This is the same as the first time that modern people have seen ancient houses.

"Boom boom boom!"

"Master Hou! The subordinates have all the things you want!"

I don’t know how long it took, and Pang Feiji’s knock was heard outside the door. Li Zexuan put down the manuscript in his hand and looked up: "Come in!"

With a "squeak", Pang Feiji came in with a sack.

Li Zexuan frowned upon seeing this and said: "Did you mix everything in one sack?"

Pang Feiji hurriedly put down the sack, opened the mouth of the sack, and said, "No, no! Lord Hou, it's all wrapped in small packets of paper!"

Li Zexuan nodded with satisfaction, and said: "Okay! Good job! You go to the front yard and guard, Benhou wants to go to the back yard to do something. No one is allowed to come to the back yard without my order!"

Pang Feiji nodded, and replied: "Yes! Lord Hou!"

Then he couldn't help asking: "Master Hou, what are you going to use these things for? Uh..."

After that, Pangfeiji immediately regretted it. In the big family, the most taboo thing is to know too much!

Li Zexuan was not angry. He raised his eyes and glanced at Pang Feiji, and said, "You will know it by then! By the way, did you destroy the previous list?"

Seeing that Li Zexuan did not blame himself, Pang Feiji exhaled relievedly, and then replied: "The list is here, it has not been destroyed!"

Li Zexuan picked up the sack with one hand, walked out the door, and said lightly: "Remember to burn the list later!"

Pang Feiji was stunned, then said: "Yes!"

But where is Li Zexuan beside him now? The latter has already gone to the backyard to make things!

...................

"Msang, my concubine is back!"

Towards noon, Han Yuxi came back from Chang'an City. As soon as he entered the house, he yelled inside as usual, but there was no response from inside.

At this time, Xiao He came out from nowhere and said, "Madam, Master is doing things in the backyard alone!"

"Oh! Then I will check it out!"

Han Yuxi put down a package in her hand, then clapped her hands, raised her feet and walked towards the backyard.

Of course Pang Feiji, who was guarding the front yard, heard it, but he would not foolishly stop him. Although Li Zexuan told him not to let outsiders into the backyard, Han Yuxi was obviously not an outsider!

"Lady, are you back?"

In the backyard, Li Zexuan is using glue to make a thick paper tube. The hole of the paper tube is about a little bit thicker than the thumb, and the tube is about 20 centimeters high. There are scattered around him. material.

Speaking of glue, many people subconsciously thought that there was no glue in ancient times. In fact, there are, but it is not chemical glue in the modern sense!

The glue currently used by Li Zexuan is fish swim bladder glue. As the name suggests, it is made of fish swim bladder. The fish maw is steamed, boiled, mashed, filtered and other procedures, and finally the fish maw glue is obtained. When using it, heat it with water and melt it and apply it on the surface of the wood. After cooling and drying, it can be successfully bonded. In terms of viscosity, it is much stronger than most modern glues!

In addition to fish swim bladder glue, there is also pig skin glue, which is made of pig skin. After boiling, it becomes something like glue. It is heated in water when used, and the method of using fish swim bladder glue is the same.

It can be said that the wisdom of the ancients in tools and materials is not as weak as most people think!

Li Zexuan, who was playing in the yard, heard the sound of footsteps and said without looking back.

Knowing people by hearing, this is the tacit understanding between "old husbands and old wives"!

"Hmm! Sang Gong, what are you doing?"

Han Yuxi couldn't help but curious when seeing the paper tubes lying on the ground and other materials scattered everywhere.

Li Zexuan thought for a while and said, "Well...I'm making something similar to firecrackers for my husband, but it's not only louder than firecrackers, but also better-looking than firecrackers! Lady, you just came back, go and rest. Well, my husband will be done in a while!"

Yes, Li Zexuan wanted to make fireworks. At this time, the "firecrackers" wrapped in gunpowder in paper hadn't appeared yet. There were only "firecrackers" or "firecrackers". To put it bluntly, they were bamboo poles. Each section is closed. When heated by a fire, the gas inside expands. If it continues to be heated, it can swell the bamboo pole~IndoMTL.com~ so it is called a firecracker.

Generally, during the Chinese New Year, the bear kids like to play this thing the most. You can often see bear kids throwing bamboo poles into the fire in groups on the street. They mainly want to listen to it!

Official gunpowder firecrackers were only recorded in the Northern Song Dynasty, and they were also called "guns" at that time.

Li Zexuan’s fireworks that can only be lifted off with the help of gunpowder are definitely not in the Tang Dynasty...

Second more!

The sequelae of the continuous explosion last month finally broke out. Fortunately, I dreamed that Daochang Sun prescribed a prescription. The knight came back to the pharmacy to grab a prescription according to the prescription. After he came back, he soaked his hands for half a while By the hour, I feel much better, and I can spend a few more days! Sun Daochang is awesome!

Okay, let’s talk about it. The prescription was prepared by the old Chinese doctor in the previous hospital. I just remembered the prescription and used the prescription! hhhh!
