Three Kingdoms: Cao Cao, please answer the question!

It is said that tens of thousands of barbarians freeze to death every winter.

As long as they know that Cao Cao is empty, he will definitely lead his army to make trouble in the north.

On the other side, he had Cheng Pu, Huang Gai and the others come back from the guarded place.

Sun Jian's plan has already been told to him. The [-] troops mobilized need to occupy Lu'an, Chengde, and Shouchun counties, so that Hefei can be turned into an isolated island.

After the answering field is over, Cao Cao may not be able to mobilize an army to rescue these three counties firmly.

Moreover, Sun Jian has already sent people to Xudu to meet Liu Xie in secret. As long as Liu Xie obstructs from the rear, Hefei will be an isolated island.

Sun Quan couldn't help sighing that his father is worthy of being a father.

In a blink of an eye, the situation where I was exhausted became beneficial to my side.

As long as things are done, or the answering question is over, it will be Cao Cao's death day.

……

Huainan County, southeast of Hefei City.

Zhou Yu was lying in the tent, looking like he was seriously ill.

Zhou Yu vomited blood in the Jiangdong Army, and the news spread like wildfire.

It's no wonder that Zhou Lang has never experienced such humiliation in his proud life.

It was originally a design, but it lost his wife and lost his army. He didn't know how much infamy he would bear because of it.

In fact, he might not feel so guilty if he sent it to anyone else, but Sun Shangxiang is Sun Quan's most beloved sister.

Veteran Gan Ning sat on the side of the couch and persuaded: "The governor is not a god, and this matter is not the governor's fault."

Zhou Yu just couldn't figure it out for a while, so he asked Gan Ning to help him sit up, and asked, "What's the matter with Cao Cao?"

"I didn't find out that our army has a lot of people, and the Cao thief dare not go out of the city."

"It's better to say that Cao Cao is already in a state of desperation."

Hearing Gan Ning's words, Zhou Yu asked in confusion, "What happened?"

"This is about your clever plan, Governor. The spies in the city developed some informants, and one of them is a man from the blacksmith shop in Hefei."

"From that mouth, the spies learned that Cao Cao arranged for two people to make things in the blacksmith shop, one for weapons and the other for stone."

"I don't know the exact number of that person, but both of them were rewarded for answering the questions." Gan Ning spoke briskly, hiding a little joy.

He continued: "Guess what? The furnace exploded, killing one of them on the spot!"

……

Chapter 169 Capture!

"How could the furnace blow up so easily?" Cao Cao said with veins on his forehead.

If only the furnace exploded, he wouldn't be so angry.

The point is that the soldier who knew how to make concrete also died.

The person who came to report was from the official temple (yamen) in Hefei City.

With sweat on his forehead, he said, "Prime Minister, maybe the things he made are not safe. After all, the furnace is made of iron. I have never heard of it burning stone."

This matter itself is not easy to investigate, and now there is only such speculation.

Cao Cao suppressed his anger, and said coldly: "Even iron can be burned, why can't stone?"

"You must find out the reason for me, otherwise I will ask you."

If other officials dared to fool around, but it was Cao Cao in front of him, with a terrifying power, the official could only reply tremblingly: "I will definitely do my best!"

When he stepped out of the door, the official was about to cry.

In his opinion, this is an accident in itself, and there are no other reasons.

At this time, the colleague stepped forward and asked, "How?"

"What else can we do? If this matter cannot be done, our heads will fall to the ground!" Before and after the official's statement, his colleagues were also sweating.

"How can this be good?"

The two were impatient.

"How about finding someone to take the blame?" The official finally thought about it, and this was the only way.

"You think the head is not falling fast enough?" The colleague shook his head, disagreeing with such a decision.

"Arresting and interrogating all the people who were present at the time, we can always find some clues. When the time comes, we will deliberately guide everyone to say that there is something wrong with that person."

This kind of local thief Cao has a lot of tricks, and it seems that it is not the first time that the other party has done this.

Thousands of people pointed out that it was yellow mud falling off the crotch, who would believe it if it wasn't shit!

Because it was Cao Cao's order, their heads are now tied to their belts, and these thieves are extremely efficient in their work.

In less than half a day, everyone in the blacksmith shop was arrested and interrogated one by one.

The so-called torture was a trick, and soon someone provided clues, saying that an apprentice blacksmith was sneaky that day.

Afterwards, the thief Cao Yan asked his subordinates to guide him, and some people said they didn't know, okay, let me ask you, was XX suspected at the beginning?

Of course those people nodded immediately, yes, yes, it was that person, that person must have done it.

Well, the case is clear!

Before the next day, the sinner was brought before Cao Cao.

This efficiency surprised even Cao Cao himself.

"Is this person responsible for the furnace explosion?"

The thief Cao Yan nodded immediately, and said: "It's not wrong. The officials interrogated all the people who were present at that time, and those people said that this person was acting sneaky before the explosion."

"If there are only one or two people, it can only be said to be framed, and the lower officials dare not confirm it, but if more than a dozen people all agree, it is a bit deliberate."

The thief Cao Chuan didn't blush, but his heart was beating wildly at this moment.

If Cao Cao saw anything, he would have his whole family killed.

Therefore, in his words, he did not definitely say that this person was guilty, but only said that everyone else believed that this person was guilty.

Kneeling on the ground was a black and thin young man. If he hadn't seen the weather-beaten face, he might only be regarded as a child from the back.

Because this person is no more than five feet tall and is as thin as a woman.

The young man was trembling at this moment, his face was full of fear, his hands and feet were tied so he couldn't escape.

His mind was still blank at this moment, he was clearly so careful, why did he feel that his actions were clearly seen by others?

That's right, all the things this man did.

The reason is very simple, but it's just spending money to be bribed.

"Tell me why you did this!" Cao Cao looked coldly at the young man kneeling on the ground.

The gap between the two is so huge.

One is the hero of the world, and the other is an apprentice blacksmith who is just precarious.

A gleam of jealousy suddenly appeared in the eyes of the dark young man, he gritted his teeth and said: "You people who are born with good looks look at us like dogs, hehehe, I wish you all died."

"Cao thief, you are the most damned one in the world!"

Looking at the hatred in the young man's eyes, Cao Cao's expression was calm.

And that thief Cao Jun's eyes jumped sharply, his brows were erected, he drew the sword from his waist, and slashed at the young man.

Before the sword fell, it was blocked.

The thief Cao Yan saw that it was Le Jin who had recovered a little and blocked the sword.

Le Jin said: "Are you going to let the Prime Minister see this filthy blood?"

Cao Cao, the thief, knelt down immediately, "Don't dare, the lower officials are also angry. How dare this person say such words to the prime minister."

"No problem." Cao Cao looked at the dark young man and said, "This person doesn't have the guts to do this. There is someone behind him, you go find it."

"Yes!" The thief Cao Cao trembled in fear.

At that time, he actually wanted to kill people to silence him, so that Cao Cao would not know that the sinner was a fake.

But at this time, he also came back to his senses. Although this person did not admit it personally, the words just now expressed that he did this thing.

Unexpectedly, it turned out to be unintentional, and the real criminal was found.

The thief Cao Cao asked someone to carry the young man and left.

Cao Cao looked at Le Jin and said, "Why did you stop him then?"

Le Jin's face was complicated, and he said, "You must feel pitiful!"

He had a short appearance and a bad birth since he was a child, and he suffered humiliation from a young age.

Looking at the young man, he only felt a bit like himself at that time, so he shot.

"That person may not be able to confess to the person behind him. Wen Qian, take someone to investigate in detail. I suspect that Zhou Yu set up a secret hand in the city." Cao Cao said.

Le Jin nodded: "Such people are usually bribed, so there are traces to follow."

As Cao Cao said, the next day the thief Cao Chuan came again and reported: "Prime Minister, that man will not confess when he dies, but we found some strange stones from his residence."

"The lower official suspects that he used these to make the furnace explode."

The thief Cao Zhu ordered someone to bring up the stones. One looked like a white crystal, and the other looked like a yellow crystal.

Cao Cao looked at it and said in surprise, "It turned out to be the second of eight stones."

These eight stones refer to the eight ores of cinnabar, realgar, mica, sky blue, sulfur, Rong salt, saltpeter, and orpiment used in Taoist alchemy.

The royal family always wanted to live forever, and so did Cao Cao, so he had studied the eight stones and recognized them at a glance.

These two stones are saltpeter and sulfur.

Put two stones into a charcoal-burning stove, and the combination of the three is gunpowder, isn't it?

No wonder the stove would explode.

But people don't know this yet.

"The one who can use these two stones may be a Taoist, the thief Cao Cao. Is there a Taoist temple in Hefei?" Cao Cao asked.

The thief Cao Cao thought for a while and said, "There is no Taoist temple in the city, but there is a wandering Taoist priest who traveled here three years ago and settled down."

He realized that the Taoist priest might be behind the young man, so he said: "Prime Minister, don't worry, I will send someone to arrest the Taoist priest immediately!"

Then go back to the outside of the city.

The soldier who answered the question got some plant seeds and the knowledge in his mind.

"What's the use of this seed?" Lu Meng asked Zhou Yu who was resting on the couch.

The soldier explained: "This seed is a kind of rapeseed."

Rapeseed existed in the Han Dynasty, but it was not planted on a large scale, and most of the rapeseed was also distributed in the west, so there was basically no vegetable oil in this era.

But Zhou Yu knew it. He asked, "What's so special about this rapeseed?"

If it is the same as the original rapeseed, then it is of no value at all.

The soldier replied: "There are also types of rapeseed. The original rapeseed is called cabbage-type rapeseed. There are two types, one is small cabbage, and the growth environment is strict."

"The other is brassica, although it is easier to grow, but the yield is relatively low."

"And the rape in my hand is called Brassica napus, which is native to exotic western regions. This kind of rape has a high yield, is easy to grow, and won't freeze to death in winter."

"Except for slow growth, there are no other disadvantages. Especially after the oil is produced, the remaining dregs can be used to feed livestock."

Oil is fat and calories, and the main source of fat in the Han Dynasty was animal fat.

But who can afford it?

If this rapeseed can grow several million acres, Zhou Yu feels that the whole Jiangdong will not worry about oil.
