"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 page of the list of materials and instructed Pang Feiji.

Pang Feiji didn't look at it, so he took it and hugged his fist and responded: "Yes, Master Hou!" ”

With that, he turned and went out.

Li Zexuan hurriedly stopped him, and ordered with a stern face: "You keep this list for Benhou, if you lose it or are looked at, you won't be able to take your life!" You know? ”

Pang Feiji subconsciously straightened his waist and said solemnly: "Understood! Master Hou! The subordinates will definitely protect the secrets! ”

Walking out of the courtyard, he took out the list of materials given to him by Li Zexuan from his arms and looked at it, and was suddenly a little dumbfounded, "This!" This...... What does Master Hou want these things for? Do you want to keep it for the New Year? ”

Previously, Li Zexuan asked Li Gang to write a couplet, although Pang Feiji was not at the scene, he also guessed that Li Zexuan was preparing for the New Year, but what do these things 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 figure it out, so he finally had to carefully put the list into his arms and walk down the mountain.

After instructing Pang Feiji, Li Zexuan returned to the study and continued to repair the book.

In fact, he had already compiled some of the textbooks for the second semester of the academy a few months ago, and after so many days of retreat, in general, basically the textbooks for the second volume were almost written, and now his main job is proofreading.

The house was quiet, only he and the two little maids, Han Yuxi went to Chang'an in the morning, and the rest accompanied Ye Guozhong and Mrs. Ye to visit the academy.

That's right, these people haven't gotten tired of shopping in the academy for several days, and Li Zexuan sometimes can't figure it out, isn't it just a bunch of reinforced concrete buildings? Is it that appealing?

This product is purely standing and talking without backache, and he doesn't want to think about it, Ye Guozhong and Mrs. Ye are both natives of the Tang Dynasty, can you not feel fresh when you see the tall cement building? It's the same as when modern people see an ancient mansion for the first time, and it's strange not to think it's new.

"Bang bang bang!"

"Master Hou! You've got everything you want! ”

I don't know how long later, there was a knock on Pang Feiji's door outside the door, Li Zexuan put down the manuscript in his hand, looked up and said, "Come in!" ”

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

Seeing this, Li Zexuan frowned and said, "Did you mix everything in a sack?" ”

Pang Feiji hurriedly put down the sack, opened the mouth of the sack, and said, "No, no! Hou Ye, you see, it's all wrapped in a small bag of paper! ”

Li Zexuan nodded with satisfaction and said, "Okay!" Well done! You go to the front yard to guard, Ben Hou wants to go to the backyard to make something, no one is allowed to come to the backyard without my order! ”

Pang Feiji nodded and responded, "Yes!" Master Hou! ”

Then he couldn't help but ask, "Master Hou, what are you going to do with these things?" uh...."

After saying that, Pang Feiji immediately regretted it, in the big family, the most taboo thing is to know too many things!

Li Zexuan was not angry, he raised his eyes and glanced at Pang Feiji, and said, "You will naturally know when the time comes!" By the way, did you ruin the previous list? ”

Seeing that Li Zexuan didn't blame himself, Pang Feiji exhaled with relief, and then replied: "The list is here, and it hasn't been destroyed yet!" ”

Li Zexuan lifted the sack with one hand, walked towards the door, and said lightly: "Remember to burn the list in a while!" ”

Pang Feiji was stunned for a moment, and then said, "Yes!" ”

But where is Li Zexuan next to him at this time? The latter has already gone to the backyard to make things!

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

"Xianggong, the concubine is back!"

Near noon, Han Yuxi came back from Chang'an City, and as soon as he entered the house, he habitually shouted inside, but there was no response from inside.

At this time, Xiaohe came out of nowhere and said, "Young lady, the young master is doing things in the backyard alone!" ”

"Oh! Then I'll check it out! ”

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

Pang Feiji, who was guarding the front yard, of course heard it, but he wouldn't be stupid to stop it, although Li Zexuan told him not to let outsiders enter the backyard, but Han Yuxi was obviously not an outsider!

"Lady, are you back?"

In the backyard, Li Zexuan was gluing a thick paper tube, the aperture of the paper tube was about a little thicker than his thumb, and the height of the tube was about 20 centimeters, and there were materials scattered around him.

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

The glue Li Zexuan uses now is fish maw glue, which, as the name suggests, is made from fish bladder. The swim bladder goes through the procedures of steaming, boiling, pounding, filtering, etc., and finally the fish maw glue is obtained. When used, it is heated over water, and after it is melted, it is coated on the surface of the wood, and after it is cooled and dried, it can be successfully bonded, and the viscosity is much stronger than most modern glues!

In addition to fish maw glue, there is also pig skin glue, which is made of pig skin, which is boiled to become something like glue, and it is also heated over water when used, which is the same as the use of fish maw 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 tinkering in the yard, heard the footsteps and spoke without looking back.

Hearing the sound and knowing people, this is the tacit understanding between the "old husband and wife"!

"Hmmm! Xianggong, what are you doing here? ”

Han Yuxi saw paper tubes lying on the ground, and other materials scattered everywhere, she couldn't help but be curious.

Li Zexuan thought for a while and said, "Hmm... The husband is making something similar to a firecracker, except that it is not only louder than a firecracker, but also more beautiful than a firecracker! Lady, you just came back, go and rest, it's almost ready for your husband in a while! ”

That's right, Li Zexuan just wants to make fireworks, at this time the "firecrackers" wrapped in gunpowder in paper skin have not yet appeared, only "firecrackers" or "firecrackers", this thing is a bamboo pole to put it bluntly, because the bamboo pole is closed one section after another, when heated by fire, the gas inside expands, and if it continues to be heated, the bamboo pole can be inflated, so it will be called a firecracker.

Generally, during the Chinese New Year, the bear children like to play with this thing the most, and you can often see the bear children on the street throwing bamboo poles into the fire in groups, they mainly want to listen to the sound!

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

The kind of fireworks that Li Zexuan is making now that can only be lifted into the air with the help of gunpowder will definitely not be available in the Tang Dynasty......

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

The second update!

The sequelae of last month's continuous explosion finally broke out, fortunately, I dreamed that Sun Daochang prescribed a prescription, and the knight came back at night in the pharmacy to grab a pair of medicines according to the prescription, and after coming back to boil his hands, he soaked for half an hour, and felt much better, and he could waste a few days! Sun Daochang is awesome!

Well, to put it mildly, the prescription was prepared by the old Chinese medicine doctor in the previous hospital, I just memorized the prescription and grabbed the medicine according to the prescription! hhhh！
