Three Kingdoms: Cao Cao, please answer the question!

For example, if the crops grow slowly, the plants are short, and the leaves are yellow, it can be initially determined that there is a lack of phlegm fertilizer.

Among the livestock manure, sheep manure has the highest sputum content.

It also records how to quickly decompose human and animal manure. If it is cold winter, you can add grass ash, straw, etc. to cook in an iron pot...

Whoops, anyway.

The knowledge in this book greatly expanded Cao Cao's knowledge.

Especially as written in the notes, corresponding fertilization can double the yield of crops.

Although it is only doubled, if it is implemented nationwide, it can feed millions of people.

Now the average yield per mu is three stones, and if you do more, it will be more than four stones.

Doubled, seven or eight stones per mu, I can't even think about it.

But because he had potatoes that could yield seventy or eighty shi per mu before, Cao Cao seemed very calm.

He gave the book to Kuai Yue, and said solemnly: "Order people to extract multiple copies, and let Kuaiqi send it to Jia Xu. This method must be popularized."

Kuai Yue took it and flipped through it, and the expression on his face gradually became serious.

"This is!"

"There is such a book!"

"With this book, the world may no longer have to worry about food!"

"In this case alone, the Prime Minister will be famous forever!" Kuai Yue said excitedly.

For internal affairs talents, perhaps the livelihood of the common people is considered.

And for counselors, this is also of great significance. If the production of food and grass increases, it means that there is no shortage of food and grass.

The most scarce thing in the world now is food. One can imagine the value of this book in today's world.

Kuai Yue intends to copy it himself, not by others.

This book is of great significance to the world!

Cao Cao said to the soldier who received the reward: "Good job, come here, reward one hundred catties, one thousand catties of silver!"

The soldier burst into tears, had to kneel down on the spot, bowed his head and said: "Thank you, Prime Minister, for your gift!"

Although gold and silver are not currency in circulation, their value is there. A hundred catties of gold is 600 taels. If everything is converted into silver, it is more than 3 taels.

The purchasing power is almost ten million.

In an instant, this soldier became a rich man, basically three generations without worrying about money.

Chapter 94 Wang Mang Skull

At this time, Guan Yu had already landed on the north bank with the [-] trapped camp.

They bypassed Shi Yang and headed straight towards Xiling.

During the march, I saw streamers flying to the front.

Guan Yu looked serious, "This is already the third streamer, and I don't know if it's the elder brother who got the reward or that Cao Cao."

Thinking that Cao Cao had entered the answering space twice, Guan Yu's heart tightened.

If Cao Cao is allowed to get an army like the Eight Hundred Siege camp, will he be able to rescue his eldest brother during this trip?

There were already elite tiger and leopard cavalry around Cao Cao. Although the leopard cavalry led by Cao Chun had been beaten and maimed by them, Cao Cao still had three thousand tiger cavalry by his side.

The eight hundred camps are also cavalry, and they all walk on two horses without rest.

When bypassing Xiakou, Guan Yu took a look, and sure enough, Xiakou had already been occupied.

There are not many Cao troops on the city wall. Looking at the ruts and hoof prints on the mainland, there is no accident. Cao Cao has already gone to Xiling.

Guan Yu felt anxious in his heart.

Li Wei, the general who fell into the camp, followed Guan Yu on the road to learn the knowledge of commanding the army. Although he is still a little green now, it is still much better than before.

After the fifth question, the curtain covering the entire Jiangxia County has not been lifted. According to the time, it is already sunset.

But the whole sky was still like the day at noon.

As white as they were in the space before.

"Could it be that there is still a sixth question that can't be solved?"

Sure enough, the words in the sky resurfaced.

The sixth question appeared!

[Question [-]: The skull of Wang Mang of the Han Dynasty was treasured and burned __ years later? 】

[This question is a fill-in-the-blank question]

It's not the easiest multiple choice question.

Guan Yu's pupils shrank, and it was unknown how many people would die in this wave.

In the middle of answering the questions, there is no punishment for correct answers and wrong answers. He originally thought it was a blessing from the immortal, but now that 'immortal' has shown his ruthless side to the world.

After these problems, the people of Jiangxia County may die tens of thousands of people.

Passing by a small village, Guan Yu saw an old man being swallowed by blue flames.

These old people are probably answering the questions with the mentality of giving it a try. If they get it right, they will be rewarded by the immortals.

But Guan Yu understands that this is not as simple as a fight, the people in the village are pale and emaciated.

All the trees around the village were stripped of their bark.

In the whole village, not a single cow or chicken or duck was seen.

He saw a child pull out a fat worm from a tree hole and stuff it into his mouth happily.

This is troubled times.

Even if they answered the question incorrectly, they would be swallowed by blue flames, and dying without pain would actually be a relief for them.

Seeing such a situation, Guan Yu couldn't help feeling resentful.

Chitu left the team, he threw the dry food stored on his horse into the village, and resolutely turned back to the team again, without seeing the looting scene in the village.

……

Wang Mang's head?

Not many people know about it.

Liu Xie knew it, and so did the powerful eunuchs in the palace.

After Wang Mang's death, the royal family of the Han Dynasty has been collecting Wang Mang's skull to remember the hatred of the Han family.

Now that the world is in chaos, Liu Bei, Sun Quan, and Cao Cao don't know who is another Wang Mang.

"When did Wang Mang die?" Liu Xie asked.

The eunuch replied: "Your Majesty, it is the fourth year of the Emperor's calendar!"

Liu Xie has been dominated since he was a child, and has not read many books. When is the fourth year of the Dihuang calendar?he does not know.

The eunuch also knew that Liu Xie didn't know, so he calculated in his heart and said: "It's been 180 years since now."

Liu Xie sat on the collapsed bed, and a court lady brought fruit to feed him.

His eyes lit up suddenly, and he said, "You said if I burn Wang Mang's head right now, wouldn't that change his answer?"

If Cao Cao were here, he would be surprised that Liu Xie had such a brain.

But it is a pity that the answer area is not in Xuchang.

It is also a pity.

"Your Majesty, the old treasury is still in Luoyang, and Wang Mang's head is also in it."

"Besides, what can we do even if we change it? Do we have to notify someone of the correct answer?"

After hearing this, Liu Xie felt bored, but he still thought: "If Cao Cao wants to answer this question correctly, he will probably need a lot of lives."

"If there are too many piles, I'm afraid his army will be in chaos for a while."

This is the truth.

So everyone feels a headache about this problem.

Even a top strategist like Zhuge Liang and Zhou Yu felt helpless.

sand envy.

Sun Quan asked Zhou Yu, "Do you know the answer?"

Zhou Yu shook his head: "I am not a person born with knowledge. If Wang Mang's head has been destroyed, then only the royal secretaries will know exactly when it was destroyed."

"And if it hasn't been destroyed, then I don't even know."

"After all, what I study is the Four Books and Five Classics, and what I read through is the art of war, not the secrets of the royal family."

As he spoke, he looked at Zhuge Liang, only to see Zhuge Liang holding a tortoise shell, and seemed to be muttering something.

"Don't say that your crooked method can be counted when Wang Mang's head was destroyed!"

After hearing this, Zhuge Liang raised his head and said, "Of course not. I'm just thinking about something. This can calm me down."

The whole hall felt speechless.

Of course, that was just an excuse, Zhuge Liang was actually counting, Wang Mang has been dead for 180 years!

"So Mr. Zhuge found the answer?" Sun Jian asked.

Zhuge Liang said: "Of course, but it's a bit cruel."

Zhuge Liang's method is indeed cruel, that is, to use captives to answer questions.

They fought several times and captured thousands of people. They killed a group before, but now they captured the Jingzhou navy.

The reason why I didn't use prisoners to answer the question just now is because I don't know what the reward is. If the [-] trapped camps were given to Cao Jun, wouldn't they suffer a lot.

Now the answer is too difficult to find, and this is the only way Zhuge Liang can think of.

Sun Quan was a little hesitant about this method. After all, it was too inhumane. As a monarch, he must not take such immoral actions.

Sun Jian understood, so he personally ordered people to bring the prisoners up.

Of course, Zhuge Liang's side would not hand over the reward to others, and they also brought a group of captives.

"If any of you can answer correctly, I will not only let you go, but also reward you with money."

No one wants to die, they know that this is their only way to survive, but no one dares to say it, because he doesn't know whether what he said is right or wrong.

Sun Jian saw that the man who had been pulled up did not speak, so he drew his sword and chopped off the man's head.

He shouted: "If you don't answer, you will die!"

Finally someone tremblingly began to speak.

"One year!"

Unsurprisingly, the flames engulfed it.

The captives behind looked like concubines.

"Two years..."

"Three years..."

On Zhuge Liang's side, there are no people who understand the royal family, so of course they can only use this stupid method. They don't know that Wang Mang's head is still there.

If you want to know the royal family, there is probably only one person in the entire Jiangxia County.

That is Cao Cao!
