However, thinking of Lu Chen's 'strict' order just now, Sakura didn't dare to act rashly, she was afraid that she would make Lu Chen angry if she spoke again. Pen? Interesting? Pavilion wWw. ｂiquge。 Info Gradually, under Lu Chen's gentle rubbing, Sakura's ankle was no longer as painful as before. Feeling the gentle movements of her feet, Sakura timidly glanced at Lu Chen, who was helping her knead her ankles, and for some reason there was a hint of sweetness in her heart.

After a while, Lu Chen disposed of the potion on Sakura's ankle, and then put her shoes back on. got up and smiled and said, "Okay, you go for a walk, are you feeling better now?" ”

saw Sakura still with her head down, silent. Lu Chen looked at her with some confusion and asked again.

It wasn't until then that Sakura reacted, and she said in a bit of a panic, "Huh? Good.. Much better, thank you Shizi"

Looking at Sakura, who seemed to be frightened, Lu Chen shook his head and said helplessly, "You haven't stood up yet, how can you know?" ”

Hearing Lu Chen's words, Sakura, who was already a little panicked, suddenly blushed and buried her head in her chest again.

Seeing this, Lu Chen could only shake his head and said, "You go back to rest first, try not to go out if your foot hurts like this." As for eating, I'll help you bring it back. ”

Hearing that Lu Chen was actually going to serve her for dinner, Sakura hurriedly refused, "Shizi doesn't need it, my foot injury is not very serious, and Shizi has also dealt with it, and it will be better soon." If my wife knew that the prince was serving me, I guess I would be beaten to death by my wife."

Lu Chen persuaded a few more times, and after seeing that Sakura didn't agree, Lu Chen could only helplessly let her go. Because Lu Chen traveled from his previous life, his concept is a little different from that of the people of the Tang Dynasty. In his opinion, there is nothing wrong with doing these things just by doing them.

Immediately, Lu Chen waved his hand and said, "You go back and rest first, don't come to serve me again." Wait until your foot is healed. Otherwise, I'll tell my mother that you're disobedient."

Hearing this, Sakura's face turned pale, and she hurriedly said, "Shizi, I just listen to you, don't say this to Mrs., otherwise I will be miserable~"

Seeing Sakura's pitiful look, Lu Chen touched her hair and said with a smile, "Go back and rest, I was joking with you just now."

When Sakura left, Lu Chen immediately took some money and walked towards the East Market of Chang'an City. After the little accident just now, Lu Chen's heart had already thought of what hole cards he should bring to support the Shannan West Dao Jiedu envoy this time.

Although Lu Chen doesn't know much about the making of bombs and their ingredients. However, he still knows how to make the simplest black powder. Moreover, according to the historical records of his previous life, this black powder should have appeared in the late Tang Dynasty. According to Lu Chen's understanding of this Datang, the black powder should not have been discovered yet.

Black powder is the product of a mixture of nitrate, sulfur and charcoal, which can produce an explosion when burned, and its principle is very simple.

This time, Lu Chen came out, mainly because he wanted to buy some raw materials, and then make his own bomb based on his understanding of black powder in his previous life.

Among the three raw materials for making black powder, saltpeter and charcoal are easy to find, charcoal needless to say, as for saltpeter, if you really can't find it, you can also extract nitrate from the soil, and the most rare is sulfur.

Although this kind of thing, Lu Chen is not very unfamiliar, and in his previous life, sulfur was also very common. But now he is in the Tang Dynasty, and if he wants a lot of sulfur, Lu Chen can only go to the crater, where the rocks are rich in sulfur.

But according to Lu Chen's knowledge, there seems to be no volcanic eruption near this Chang'an City, only in the far west or north, there is such a volcano. If Lu Chen went to that kind of place to look for sulfur, I am afraid that before he came back, the battle between the Shannan Xidao Jiedu envoy and the Yizhou Taishou would already be over.

While thinking about it, Lu Chen had already walked out of the Lu Mansion. He wandered aimlessly on the street, constantly thinking about how to get a large amount of sulfur, and just as he was thinking, Lu Chen looked up and saw that he had come to Datang Express at some point.

Seeing this, Lu Chen simply stopped wandering around, turned around and walked in through the back door of Datang Express. After all, Song Cai was also a well-informed businessman before, so maybe there would be some good way.

After meeting Song Cai, Lu Chen asked him about sulfur.

Hearing that Lu Chen needed sulfur, Song Cai stared at Lu Chen for a long time in puzzlement, and then asked slowly, "Is the young master going to learn alchemy?" Although this alchemy sounds very good, it is too illusory, I hope the young master will not be obsessed with alchemy and waste the great cause! ”

After hearing Song Cai's persuasion, Lu Chen was a little confused, and asked in a daze, "I didn't say that I was going to alchemy, I just wanted to ask you where there is sulfur." How can it be related to alchemy? ”

Hearing Lu Chen's words, he saw that Song Cai said very naturally, "Sulfur is a thing, except for those alchemists, no one else can use it." If the young master really wants to find these things, he can go to those alchemists. There must be these things in those people's alchemy rooms."

Hearing this, Lu Chen nodded abruptly and asked again, "Do you know where alchemists are in general?" I urgently need a lot of sulphur right now."

Seeing that Lu Chen was very eager, Song Cai thought for a while and said, "These people are generally in some unknown places, silently refining the legendary elixir, and it is not very easy to find them. However, we can release the news and buy sulfur with a lot of money, and I believe that these people will definitely come to trade once they get the news. After all, these people have already spent all their money in order to buy alchemy materials."

Hearing this, Lu Chen nodded and said, "Just follow the method you said, money is not a problem, how much sulfur you want." ”

Now that the sulfur has landed, Lu Chen left Datang Express and came to Dongshi. Here, Lu Chen quickly found the person who sold saltpeter. And the price of this thing is not expensive, after a little understanding, Lu Chen immediately bought all the saltpeter from that person. However, Lu Chen did not let the other party send them to the Lu Mansion, Lu Chen did not plan to make these things in the Lu Mansion, and he did not want too many people to know about it. After all, these black powders were used by Lu Chen as hole cards, and they couldn't be exposed too early.

However, Lu Chen did not find anyone who sold charcoal, after all, even if there was a sale in this Tang Dynasty, it was estimated that no one would buy it. In desperation, Lu Chen could only find someone to burn it himself, otherwise there was no way.

Lu Chen asked people to send the saltpeter he bought to the courtyard of the house he originally bought for Song Cai and the others. Then it took half a day to find someone to burn a large amount of charcoal, which was also transported to the house. (To be continued.) )
