Otaku Engineer in Great Tang Dynasty

? "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 all, he turned and went out.

Li Zexuan hurriedly stopped him, and said with a stern face: "You should 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 his waist 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, "Here! What...what does Hou Ye want these things for? Are you keeping them for the New Year?"

Earlier, Li Zexuan asked Li Gang to write the couplet. Although Pang Feiji was not present, 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 to 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.

In fact, he had compiled a part of the textbooks for the second semester of the academy a few months ago. After so many days of retreat, in general, basically the textbooks of the second semester are almost written. Now his main job It is proofreading.

The house was 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.

That's right, this group of people have been walking around the academy for several days and they haven't gotten tired of shopping. Li Zexuan sometimes can't understand it, isn't it just a pile of reinforced concrete buildings? Is it that attractive?

This product was purely standing and talking, and he didn't want to think about it. Ye Guozhong and Mrs. 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!"

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

I don't know how long it took, Pang Feiji's knock came from outside the door. Li Zexuan put down the manuscript in his hand and looked up and said, "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, I want 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 said, "Yes! Lord Hou!"

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

After saying 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 in relief, and then replied, "The list is here and it has not been destroyed!"

Li Zexuan picked up the sack with one hand, walked outside 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!

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

"Miangong, the concubine is back!"

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

"Oh! I'll go take a look!"

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 stop him stupidly. 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 was using glue to make a thick paper tube. The hole diameter of the paper tube was about a little bit thicker than that of the thumb. The tube was about 20 centimeters high. There were materials scattered around him.

Speaking of glue, many people subconsciously think that there is no glue in ancient times, but in fact there is, but it is not chemical glue in the modern sense!

The glue currently used by Li Zexuan is fish swim bladder glue, which, as the name suggests, is made of fish swim bladder. The fish swim bladder is steamed, boiled, mashed, filtered, etc., and finally the fish swim bladder glue is obtained. When using it, heat it with water, 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, which becomes glue-like after being boiled. It is also heated in water during use, the same way as fish swim bladder glue.

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

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

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

"Hmm! Xianggong, what are you doing?"

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

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

That’s right, Li Zexuan wanted to make fireworks. At this time, the "firecrackers" wrapped in gunpowder in paper had not yet appeared, only "firecrackers" or "firecrackers". To put it bluntly, they are bamboo poles. The knots are closed. When heated by fire, the gas inside expands. If the sticks are continuously heated, they can explode~www.readwn.com~ so they are called firecrackers.

Usually during the New Year, the bear kids like to play with this thing. 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.

The fireworks that Li Zexuan made now that could be lifted off with the help of gunpowder, certainly not in the Tang Dynasty...

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

Second!

The sequelae of the continuous explosion last month finally broke out. Fortunately, I dreamed that Daochang Sun prescribed a prescription. The knight came back at the pharmacy and grabbed a prescription according to the prescription. After he came back, he soaked his hands and soaked for half an hour. Much better, I have been able to wave again for a few days! Sun Daochang is awesome!

Well, speaking of humans, the prescription was prepared by the old Chinese doctor in the previous hospital. I just remembered the prescription and used the prescription to grasp the medicine! hhhh!
