There are no other problems with the production of fireworks. The only problem www.biquge.info the pen is to control the order in which the light beads burn. The order in which the beads burn depends on the amount of gunpowder wrapped around the beads.

Because there is no accurate amount, Xia Hongsheng must try again and again, recording while trying, until he finds the most suitable amount. There is no shortcut to this, even if there is a shortcut, Xia Hongsheng will not. So I can only use stupid methods, honestly add and subtract little by little, and try little by little.

Xia Hongsheng even used it during the day, trying again and again in Jingyang Academy. The hard work paid off, and finally gave Xia Hongsheng the best amount.

Zhang Laodao's side also began to make those substances containing metal ions for Xia Hongsheng day and night - there were Xia Hongsheng's personal soldiers watching outside, and Zhang Laodao thought that Xia Hongsheng was specially sent to supervise him.

Xia Hongsheng alone couldn't keep up with the progress of Zhang Laodao making those things, so Xia Hongsheng called Qi Yong again, and those relatives at home, and asked them to help make light beads and fireworks.

Set off a firework, why don't you have at least two pillars of incense? Otherwise, it wouldn't be interesting.

Therefore, Xia Hongsheng has hardly been out of the academy in the past half a month, and every day from morning to night, he is all immersed in fireworks.

As for how to hold this fireworks display, Xia Hongsheng has already thought about it.

The location is on the edge of Weihe Park, which is very open, can accommodate a lot of people, and is close to the river, which is not easy to cause fires.

Fireworks, of course, can only be seen at night. That's not a problem. The curfew started on the second watch, but it was already dark on the first watch, so the people of Chang'an City had time to go to Weihe Park to watch the fireworks display and then return home.

Then there is one last problem left in front of you - let Li Lao Er promise Xia Hongsheng to hold a fireworks display.

"Your Majesty, fireworks look very magical, very good-looking, like a goddess scattering flowers, and like light and rain, it can be called a fairyland. Let the people watch a fireworks display, first, see the beautiful scenery, relax their mood, can add some color to their lives, help people adjust their mood, put into production and life in a better state, and build Datang. Second, the fireworks are extremely beautiful, it really seems to be auspicious from the sky, if the people see it, wouldn't it make the people more proud of the Tang Dynasty and more loving to Your Majesty. Just like the last hot air balloon, His Majesty has become a god-like existence in Baixin's mind, and His Majesty's prestige has become unparalleled among all emperors in ancient and modern times. At present, Datang is about to face a new round of conquest, and it is still facing a place that has made it difficult for the people to get out of the shadow. If the people don't have a heartfelt belief and blind worship of His Majesty, how can they forget the tragedy in Liaodong before and follow His Majesty to conquer Liaodong again? ”

Xia Hongsheng stood next to Li Shimin and said eagerly to Li Shimin.

However, Li Shimin just continued to review the recitals and did not raise his head.

Xia Hongsheng scratched his head, and was about to continue to persuade, but he heard Li Shimin say lightly: "Tell the truth, tell the truth, maybe I will agree." ”

"The fireworks are very beautiful, Weichen finally made them, I want to see them." Xia Hongsheng said.

"Say it again." Li Shimin smiled and said again.

Xia Hongsheng's face was expressionless, and he said: "Soon the academy will enroll students again, and Weichen wants to use the fireworks display to make the name of the academy more famous." ”

"I went to Jingyang Academy in person and stayed for a few days. The name of Jingyang Academy is not loud now? Li Shimin asked rhetorically, and then said, "Go on." ”

"This ...... His Majesty went to the academy in person, and Weichen was grateful, and he also earned enough eyeballs for Jingyang Academy. Now the people know the name of Jingyang Academy. Xia Hongsheng said to Li Shimin: "However, the name is a good fate after all, and there must be something worthy of this name." The so-called hearing is false, seeing is believing. Jingyang Academy also has to come up with something, so that everyone can see the magic of Jingyang Academy with their own eyes, and they will believe that Jingyang Academy has the strength to match its name. ”

After listening to Xia Hongsheng's words, Li Shimin nodded, smiled again, and said, "It sounds like there is some truth. However, how did I hear that you did such a thing so that the daughter of Xu Xiaode's family would think that you were favoritism? ”

"Uh......" Xia Hongsheng was speechless, damn, who leaked the news of this son?!

Xia Hongsheng scratched his head, and said cautiously: "This, hehe, Your Majesty is really a pair of discerning eyes, Weichen does have such a lost mind, and you can see it." ”

Li Shimin glanced at Xia Hongsheng, paused, and said: "Well, for the sake of Changle and Xu Hui's good friendship, and also for the sake of you being about to go to Quanzhou and leave Chang'an, I will grant you what you want." You have a way to do things in your heart, you are not a nonsense, and I can rest assured. Go and get ready to go, don't bother. ”

"Hey! Thank you, Your Majesty! When Xia Hongsheng heard Li Shimin's promise, he immediately smiled, and said to Li Shimin: "Your Majesty, when the time comes, you can also go up to the Vermilion Bird Gate, it should also be visible!" If you don't believe it, Weichen will never deceive people, it is really good-looking! ”

"Let's get ready to go!" Li Shimin waved his hand: "If you finish your peace of mind early, you can set off as soon as possible." ”

Xia Hongsheng nodded, bowed and retired, and left the palace.

He rushed out of the palace, got into the carriage, and said to Qi Yong: "Qi Yong, go back to Jingyang directly!" ”

Xia Hongsheng thought all the way, and after returning to Jingyang, he went directly to the academy, found Xu Qixian first, told him about the fireworks display, and asked him to find a way to take Xu Hui out that night and take him to Weihe Park.

"Huh? I've seen you try so many times every day in the past few days, and you've finally done it? When Xu Qixian heard this, he was also very excited, and immediately patted his chest to reassure and said, "Okay!" No problem! Wrap it up on me! When the time comes, I will definitely bring Hui'er here! ”

Xia Hongsheng nodded and said, "Yes, it's basically formed." Try one or two more to confirm, and you're good to go. I set the time for three days later, and in the next few days, I sent people to Chang'an City to post notices, inviting the people of Chang'an City to watch fireworks in Weihe Park! ”

After explaining Xu Qixian, Xia Hongsheng went home and naturally told his family, but he only said that he would hold a fireworks show in the name of the academy, and let his sister-in-law and Yuexian go to Chang'an to live a day in advance.

Everyone in the family knows that Xia Hongsheng has been struggling with this thing for several months, but they don't know what it is. Hearing Xia Hongsheng say that it was done, they were all happy, and they were looking forward to discussing where to see and what to bring. (To be continued.) )
