On this day, there was a mess in the Prime Minister's Mansion. The many servants kept going back and forth, because Cao Cao suddenly covered his head and fell unconscious without warning...

This coma lasted for three days, during which many civil and military officers came to visit. was politely stopped by Cao Pi, the second son who accompanied him day and night, and sent away.

There are all kinds of people who come, there are those who listen to the truth and the truth, there are those who gloat, and there are many people who look at jokes and hope that Cao Cao will never wake up. Everyone gathered in the Xiangfu Mansion to stage a disdainful black humor...

The second son, Cao Pi, shook his head helplessly after sending another official away. Just as he was about to turn away, he suddenly heard someone calling for him, and he looked back. The person who came was the strategist Cheng Yu, and Cheng Yu asked with some concern:

"Childe is okay, it's been hard these days. Not only do you have to take care of the prime minister, but you also have to deal with these people! ”

Cao Pi smiled slightly.

"Don't get in the way, is there something wrong with the gentleman here?!"

Seeing that Cheng Yu seemed to hesitate, Cao Pi spoke again.

"Sir has something to say directly, this is no one else!"

Cheng Yu pondered for a moment and slowly spoke:

"It's not the first time that the prime minister's head has been blowing, it's really worrying. The prime minister has a lot of opportunities, this can't be delayed any longer, I know a warlock who can refine pills. It should be possible to eradicate it completely! ”

Cao Pi's eyes lit up, and he hurriedly asked:

"And where is this man now?!"

"I mentioned it to the prime minister a long time ago, but the prime minister has never believed in the mandate of heaven and disrespected ghosts and gods. He only believed in himself, so he didn't accept my advice, but now the prime minister is like this. I think you can still give it a try!! ”

Cheng Yu sighed and said slowly.

"It's okay, sir, you can go and get this person in first. Let him come to my house first, if I can really cure my father's illness, I will have a great reward!! Father will not blame!! ”

Cao Pi pulled Cheng Yu and said seriously.

"Okay, then I'll do it!!"

After speaking, Cheng Yu turned around and left...

Xu Tian also went to the Prime Minister's Mansion to greet Cao Cao, after being politely refused. returned to his room, the last time he proposed to Cao Cao, now Cao Cao is in a coma, and there is no warrant from him. It can't be done.

At this time, Xu Tian remembered about gunpowder again, he attached great importance to this, if it was possible to turn gunpowder into a bomb. What this will change, Xu Tian can't imagine. But I don't know much about this thing invented by my ancestors, but in my own time, bombs are already very ordinary, so I don't need to pay attention.

Thinking about it, Xu Tian decided to look through the ancient books. What the hell is supposed to be about research, where can I find it? Xu Tian thought of Xun Yu, Xun Yu was a member of the Xun family of the Eastern Han Dynasty, and he himself was a famous man in the world. There must be a large collection in the home, where you may have what you need...

Xun Yu was sitting at home, holding a wooden slip in his hand and looking at it seriously. From time to time, he put down the wooden tablet in his hand and frowned in thought. It seems that something is being studied.

At this time, the servant outside the door bent down and slowly came in and bowed to Xun Yu. Opening:

"Master, there is a person outside the door, claiming to be called Xu Tian, asking to see the master!"

Xun Yu put down the wooden tablet, looked at the visitor in some surprise, and groaned slightly.

"Go and bring him in!"

Xu Tian slowly walked into the house under the guidance of the servant. Seeing Xun Yu sitting at the table, he bowed deeply, and said with some guilt:

"In Xia Xu Tian, take the liberty to disturb Lord Xun, I hope that Lord Xun will forgive me for coming uninvited!!"

Xun Yu laughed.

"Lord Xu is polite, come on, come on, please sit down and talk!"

Xu Tian knelt on the seat next to him, his buttocks resting on his heels, and during this time, he was used to sitting like this.

"Lord Xu is here, what are you doing? If there's anything you need me to help with, please ask! ”

Xun Yu said sincerely.

Xu Tian really likes Xun Yu, Xun Yu is humble and generous, and treats people kindly. There is an air of elegance on his body, and he has the demeanor of a peerless countryman.

Xu Tian smiled slightly.

"I do have something to ask for below, and I want to find some information below. It's a pity that there are too few stores in the bottom, there are not so many books, in the next thought, Mr. Xun must have a treasure here, so I dare to ask Lord Xun to borrow it, and I hope Mr. will be complete!! ”

Xun Yu waved his hand

"It's very simple, Lord Xu wants to read, I have a lot of books, so please come with me!"

After Xun Yu finished speaking, he got up and walked out of the house. Came to a large room in the backyard.

Xu Tian followed all the way to this house. As soon as he entered the room, Xu Tian was shocked by the scene inside the house. There are all kinds of bookshelves in the room of nearly 200 square meters, and wooden tablets are densely placed on each bookcase. and some silk silk.

Looking at the books in this room, Xu Tian couldn't help but swallow his saliva.

"Whatever Lord Xu wants to see, please feel free. Each of these shelves is marked with the type, if there is something you don't understand. Just tell me. ”

Xun Yu looked at Xu Tian, who was a little dazed, and said with a smile.

Xu Tian nodded and plunged into the bookshelves. Search them one by one by the categories marked above.

Time passed little by little, and Xu Tian frowned and looked for it on the bookshelves. Xu Tian thought that this gunpowder must be considered a chemical class, but it is impossible to write a chemical class on this shelf, how to find it.

After hesitating for a moment, Xu Tian still came to Xun Yu, who was sitting at the table at the door reading a book since he entered the room. A little embarrassed to speak:

"Mr. Xun, where is the record of gunpowder, I am stupid, I haven't found it for a long time, but there is still Mr. Lao!"

Xun Yu didn't have the slightest impatience, and with a smile he took Xu Tian to a bookshelf he had walked through before, and led him to find those wooden tablets.

Looking at the classification above, Xu Tian sighed secretly and rubbed his eyebrows. scolded himself

"Xu Tian, Xu Tian, gunpowder, gunpowder, naturally in the classification of medicine!"

After finding this bookshelf, Xun Yu returned to the table and continued to read the book.

Xu Tian read them one by one and read them carefully. But most of the wooden tablets in this pile are not, but this makes Xu Tianwei make up for his knowledge of medicine.

After more than half an hour, Xu Tian found a record of gunpowder. It turns out that as early as the Spring and Autumn Period, gunpowder has been widely used in the people, those alchemists, burned honey into carbon, plus saltpeter and sulfur, can be turned into a violently burning substance. Xu Tian couldn't help but sigh secretly, the wisdom of the ancients was really admirable. It's just that maybe they didn't expect that what they summarized from life practice would become a weapon with great lethality thousands of years later.

More than an hour later, Xu Tian and Xun Yu left the room. After thanking Xun Yu, Xu Tian left here...

On the other hand, Cheng Yu invited an alchemist from the deep mountains that he had met by chance in his early years.

Situ Yun...
