Some time after the last time he returned from the palace, Xu Tian found that Wang Ling seemed to have forgotten about himself. It's no longer like before, and you have to make things difficult for yourself when you find an opportunity.

The more this is the case, the more Xu Tian feels that there is a problem. This made Xu Tian more and more interested in the person Wang Ling wanted to rectify.

On this day, Xu Tian was in the room, holding an ancient book borrowed from Xun Yu. Looking at it carefully, he wanted to know how the ancients prepared gunpowder.

According to the book, there are three main materials for the preparation of gunpowder, carbon, saltpeter, and sulfur. In addition to carbon, the other two of these three are medicines. I'm going to have to make a trip to the pharmacy.

Xu Tian decided to give it a try, although all his knowledge of gunpowder came from the fireworks in his memory. and the bomb with its terrifying destructive power.

East of the city, Rejuvenation Hall. Xu Tian looked at this huge medicine shop, and before he entered, he felt the fragrance of medicine. This place should have what it needs.

When they came to the pharmacy, a shrewd fellow quickly greeted him, smiling all over his face.

"What the guest officer needs, just tell the little one. Our rejuvenation hall is one of the best pharmacies in Xudu, and we have everything we need for medicines!! ”

Xu Tian nodded slightly.

"Are there brimstone and saltpeter?"

The guy frowned slightly, and said with some regret.

"Guest, this sulfur is there, but saltpeter needs to be specially refined. Generally, it takes an experienced alchemist to refine, but we don't..."

Xu Tian was a little disappointed and groaned slightly.

"All right, just brimstone!"

"Okay, wait a minute!!"

The guy smiled and walked to the back hall, and after a while, he came out with a small bag and handed it to Xu Tian.

Walking out of the Rejuvenation Hall, Xu Tian looked around. decided to go back first, saltpeter seems to have to think in the long run, alchemist, I don't know if Xu Du will have it.

Not far away, Xu Tian looked at it casually. I found an acquaintance, who was walking back and forth at the south gate at this time, talking to the guards at the city gate from time to time.

Xu Tian was a little curious, how did Yu Fei come to this south gate to guard the city gate. After thinking about it, Xu Tian raised his feet and walked towards the city gate...

He hadn't gone far before he stopped again. He saw an acquaintance again, and Xu Tian frowned slightly. Inner Secrets:

"This Wang Ling, as a commoner, actually came to find a city gate official. Could it be that this is Wang Ling's person?! ”

Xu Tian stood aside and watched Wang Ling slowly leave with Yu Fei. Eyes flashing...

Go back to your room and put aside the sulfur you just bought. Xu Tian decided to go and find Xun Yu, maybe he would know if there would be an alchemist in Xu Du. As long as you have saltpeter, you can try to mix gunpowder. Thinking of this, Xu Tian rubbed his hands with some excitement.

When I found Xun Yu again, Xun Yu was studying the military book. Xu Tian couldn't help but feel a little admiration, Xun Yu couldn't release the scroll as long as he had time. It's a bit overwhelming...

"Lord Xu is here!"

Xun Yu saw Xu Tian who came to the house and put down the wooden tablet in his hand. Said with a smile.

Xu Tian arched his hand at Xun Yu and said:

"I'm bothering Mr. again, I have something I want to ask Mr. about the next thing."

"Please!"

"I don't know if there is an alchemist in this Xu Capital City?!"

Xun Yu was stunned and looked at Xu Tian with some doubts

"Alchemist?! Lord Xu thought of alchemy? ”

"No, no, no, it's not. It's just that I need a material, and I need the help of an alchemist. ”

Xun Yu suddenly thought about it.

"Alchemist, I don't seem to have heard of it in Xudu City. However, these people are generally secluded, and few people know about them. Well, I'll find someone to check it out..."

Xu Tianmu was disappointed, but it was no wonder. The alchemist is a stranger, and it is rare to see it.

Xu Tian thanked him again and was about to leave. Suddenly, Xun Yu stopped him

"Wait! Oh, as soon as this person gets older, his memory is not good. Some time ago, Cheng Yu just invited an alchemist to refine the elixir for the prime minister. At this time, it should be in the Gongzi Cao Pi Mansion, you can go and visit!! ”

Xu Tian's eyes were shining, and he thanked him again. Got out of here.

Gongzi Cao Pi's mansion is in the east of Xu Capital City, and Xu Tian heard Xu Chu mention it once. After questioning a few people, Xu Tian came to the door of Cao Pi's mansion.

Standing in front of the door, Xu Tian hesitated. This prince had never seen it himself, and he came to visit it rashly in his own capacity. Is there something wrong, just hesitating, the guard in front of the mansion found Xu Tian standing here. One of them stepped forward and shouted:

"Who is staying here, don't you know what kind of place this is?!"

Xu Tian smiled a little embarrassedly and arched his hand.

"Please pass through the son, and say that the servant Shi Xu Tian asks to see!!"

The man looked at Xu Tian carefully, and after a moment, he said with some hesitation:

"Then you wait here! Don't leave until I'm back!! ”

About a quarter of an hour later, the guard walked out. took Xu Tian and slowly came to the lobby of Fuzhong.

In the lobby, a young man in a robe with a rather elegant air stood there. Seeing Xu Tian coming, this person showed a kind smile.

"Xu Yushi, right, I heard my father mention you, and my father said that you are a genius. I've always wanted to visit my husband and never had the chance. I didn't expect Mr. to come, please sit down, sir!! ”

Xu Tian returned the salute with his fists and sat aside.

"The prime minister praised it falsely, and he just cared about an ordinary person. I take the liberty to disturb Childe today, and I hope Childe forgives his sins!! ”

Cao Pi laughed.

"You're welcome, sir, what's the matter with you. But it doesn't hurt to talk about it!! ”

"I heard that there is an alchemist in the Childe's Mansion. I need a material, and I need the help of an alchemist, so I'm here to bother Childe!! ”

"This matter, yes, I have an alchemist, Mr. Cheng specially invited him to refine the pill for his father, so let's invite him here, Mr. needs to tell him, what does Mr. think?!"

"In this way, there will be Mr. Lao!!"

Cao Pi stood up, came to the door, whispered a few words to the servant in front of the door, and returned to the hall. Let's talk to Xu Tian...

Soon, the servant slowly walked into the hall with a man dressed in a Taoist robe and a mantle with a disheveled head. Xu Tian, who was chatting with Cao Pi, looked at this person casually, and the moment he saw this person, Xu Tian's eyes widened violently.

"It's !! you"
