"When it comes to making peace with Xue Yantuo, why should my father worry, not to mention, even God is helping my father." Li Chengqian said, in his opinion, Xue Yantuo's problem is not a problem.

The more than 100,000 livestock sent by Xue Yantuo of Li Chengqianji were transported on the way due to a lack of water and grass, and the weather was bad and suddenly hit a snowstorm, so that most of the livestock died.

He Li took the opportunity to persuade Li Er to use this as an excuse to reject Xue Yantuo's marriage proposal, and married Princess Xinxing to the eldest grandson Wuji's younger brother, Changsun Xi.

Now that Yi Nan is still on the way here, Chang'an doesn't know much about his situation, and he won't know that Yi Nan will suffer such a serious disaster.

In this case, why didn't he rush in front of Qi Bi He Li and put forward this suggestion, so that his father could start from this aspect.

When Li Er heard Li Chengqian's words, he knew that Li Chengqian already had an idea, and he, the crown prince, had more and more his own opinions.

Li Er asked, "Da Lang, do you have any ideas, you might as well talk about it!" ”

"Father, now the temperature has begun to turn colder, and this year's temperature is colder than ever! Maybe there will be a heavy snowstorm in the north, and Yi Nan will definitely die a lot of people who drive their cattle to Lingzhou after a long journey! Why don't you take advantage of this topic! Li Chengqian said.

In ancient times, transportation was not like that of later generations, there were railways, airplanes and other means of transportation, and it took more than half a year to collect livestock, and the speed of action was naturally slower than usual to drive such a large number of livestock.

After the winter, the water and grass in the Mobei area decreased, and the bad weather caused most of the natural deaths and injuries of these animals as a dowry.

"That's a good idea! Wang Yuan immediately sent someone to Mobei to inquire about the situation of Yi Nan, whether Mobei had already begun to snow. Li Er stroked his palms happily and laughed, not forgetting to send someone to inquire about the situation in Mobei.

"No!" Wang Yuan was ordered to retreat.

"Father! If nothing happens, the son will retire! Li Chengqian gestured at Li Er, Li Er nodded, and Li Chengqian left the Qianqiu Palace.

After returning to the East Palace, Li Chengqian instructed Wang Quan: "Wang Quan, you go and get some saltpeter, sulfur, and charcoal for the widow." ”

"No!" Although Wang Quan didn't know what the prince wanted these medicines and charcoal for, he knew that as an inner servant, he shouldn't talk too much, and the master would do whatever he asked you to do, which was the duty of being an inner servant.

"Lang Jun! I wonder how many of these pills and charcoal you want? Wang Quan asked, and the prince only asked him to get these three things back, and did not say how much.

"Get some more!" Li Chengqian said.

Li Chengqian plans to use these to make some fireworks, so that he can set off fireworks during the New Year, and there is no such thing as fireworks in Datang now.

In addition to keeping the New Year and going to various homes to pay New Year's greetings, there are no superfluous entertainment programs at all, not to mention fireworks that have not yet appeared.

Now that he Li Chengqian is here, the people of Datang are finally blessed!

As for the manufacture of fireworks, it is not a difficult task for Li Chengqian, he has not crossed over, he has worked as a short-term worker in a fireworks and firecracker factory in later generations.

The process of making fireworks and firecrackers is clear in his heart, but he has not made fireworks for so long, and it is inevitable that he will be a little rusty, so Wang Quan can prepare more, so that he can practice his hands.

"Lang Jun! Do you need a slave to find you a few alchemy Taoists to come back? Wang Quan asked.

Li Chengqian's face suddenly darkened, and he remembered that in ancient times, saltpeter, sulfur and other substances were used to refine pills at the beginning.

How did Wang Quan know that Li Chengqian wanted these to make fireworks, not to refine elixirs such as immortality at all, and Li Chengqian didn't want to live forever.

What's more, how could Li Chengqian, as a traverser, not know about these refined pills, if he really eats them, not only will he not be able to live forever, but he will also be prone to die quickly.

Wang Quan thought that Li Chengqian had forgotten that alchemy still needed an alchemy Taoist, so he kindly reminded the prince!

"No need! I have other uses for these medicines, not for alchemy, you can do as I say. Li Chengqian said.

"No!" Wang Quan took the order and left.

Wang Quan went to Yousi to get some saltpeter, sulfur, and charcoal, and the officials of Yousi thought that the prince was going to make alchemy in the East Palace, and enthusiastically recommended some alchemy Taoist priests with high alchemy level to Wang Quan, but Wang Quan refused.

"Lang Jun! The slave has already brought you what you want! As soon as Wang Quan returned to the East Palace, he hadn't seen anyone yet, but the voice came.

Li Chengqian got up and came to the outside of the hall, and saw that Wang Quan was directing people to move saltpeter, sulfur, and charcoal and put them away.

"Did you move all the inventory in the treasury?" Li Chengqian asked.

Saltpeter is not only a medicine, but also can be used to prepare malachite green glaze, multicolor, pastel pigments, sulfur is a multi-functional agent, charcoal is used to burn and heat in winter, so the treasury stores these three things on weekdays.

Looking at the saltpeter, sulfur, and charcoal in several bags of marijuana stacked separately, Li Chengqian thought that Wang Quan had searched the entire treasury inventory.

"Hui Lang Jun! The slave maid was afraid that Lang Jun would not be enough, so she specially asked them to bring all the money in the treasury. Wang Quan said.

"Keep one bag of each, and put the rest back, it's not too late to take it if it's not enough!" Li Chengqian said.

"No!" Wang Quan nodded to Li Chengqian, looking like a slave, turned around and immediately put on a straight face, and commanded the others: "What are you still doing in a daze!" Didn't you hear Lang Jun's instructions? Don't hurry up and give our family a little more trouble. ”

Everyone had no choice but to follow Li Chengqian's instructions, leave one bag of each of the three things, and then return the rest to the original way and move back to the treasury.

"Wang Quan, you asked me to grind all these medicines and charcoal into powder, separate them and don't mix them together, understand? I'll send it to the Bright Heaven Hall when I've got it. Li Chengqian said.

"Lang Jun rest assured, the slave knows how to do it!" Wang Quan responded, turned around and beckoned a few people to take the three things in the sack in front of him and grind them into powder.

An hour later, Wang Quan brought the saltpeter, sulfur, and charcoal ground into powder with his attendants in a hurry, and sent them to Li Chengqian.

Li Chengqian retreated left and right, and was alone in the Guangtian Temple to tinker with these materials, according to the memories of his previous life, he began to match these in order, and then stuffed it into the prepared bamboo tube.

Since he hadn't done this for a long time, it was inevitable that he was a little rusty, and Li Chengqian wasted the boss's strength before he made a firework.

Li Chengqian breathed a sigh of relief and muttered: "It's good that I didn't lose this art of eating, otherwise I really wouldn't be able to handle fireworks." ”

After having the experience of the first one, it was much easier to manufacture it next, and two hours later, Li Chengqian had more than 30 fireworks in his hand.
