Three Kingdoms: Cao Cao, please answer the question!

Sun Quan felt that he was not well.

A small boat rowed over from the river bank again, the boatman was still the same person, and he didn't hear a word from him.

But he saw him board the boat, walked up to Sun Quan, took out a letter, did not hand it to Sun Quan first, but patted Sun Quan on the head three times with the letter.

Sun Quan was stunned, if he hadn't known that this person was his bodyguard and had served him for many years.

Just now he was about to get violent, thinking that an assassin was coming.

The boatman knocked three times before handing over the letter to Sun Quan and leaving it.

I saw on the letter that it said, beat my son Zhongmou three times on behalf of him.

The sender was Sun Jian.

Sun Quan opened the envelope, read it carefully, and handed it to Lu Su.

After reading it, Lu Su said: "General Sun is supporting the lord, let the lord let you go, and he will stand behind you for everything."

"I'm afraid it's because of the first question!"

Sun Quan hummed lightly, he just felt a warmth melt in his heart, it's good to have relatives!

The tenderness on his face was only for a moment, and he quickly recovered, and then said: "It seems that we can no longer stay on this boat, and the next one will be a tough battle."

Lu Su nodded his head.

Back to Xu Du, the words of the ugly person were still in his ears, but at this moment he couldn't laugh anymore.

His face was flushed, his eyes kept staring at the ground, trying to find a crack to get in.

"It really is Jiang Zitong. I met him when I went to Yanzhou the year before last. At that time, he was admired by many stars and talked about world affairs among scholars."

"The situation that day is especially in front of me, and now I know that he has the talent of Wang Zuo."

There is no derogatory meaning in this sentence, only emotion.

They are still here to drink and enjoy the flowers, and Jiang Zitong is already in Yangzhou. Although he is a little wet, his official position is there.

No matter how bad it is in the future, it will be the prefect of a county, and if it is higher, it may become the governor of a state.

And now that this evaluation comes out, it makes people feel that he may be among the top three in the future.

The woman next to the ugly person had left with an excuse, leaving him alone at the table, and he suddenly said: "Let's see how the analysis is, maybe it's just a courtier."

Ning (ning) ministers are ministers who are good at flattering and flattering.

Many people looked at him with unfriendly expressions.

They have endured making things difficult again and again, but they still don't know how to turn around again and again, which is a bit unreasonable.

Immediately, someone said in a strange way: "Jiang Ji has already reached a high position, and we all know what he is capable of."

"I don't know where the second generation ancestor who ran out to do nothing, has little ability and has a lot of doubts."

"You!" The ugliness stared away angrily.

"I can only show power here. I heard that Jiang Dong is attacking Hefei, and Jiang Ji is also in Hefei. He is on the front line at this time. Do you dare to go?"

People around chuckled, even the woman covered her mouth.

The ugly person already knew that he couldn't stay any longer, so he waved his sleeves and prepared to leave.

"Don't go, look at the sky, the analysis has come out."

"Let's see if it's the sycophant you said."

The ugly person looked up, and sure enough, the analysis had appeared.

[Problem analysis: Jiang Ji was well-known in the Jianghuai area, and he was appointed as the official of Chu State when he was not as weak as the crown.

After that, he was valued by Liu Fu and became Yangzhou Biejia, and was reused by Cao Cao in the Battle of Hefei.

After the establishment of the Wei State, Jiang Ji was successively appointed as the Minister of the Prime Minister, the General of Dongzhong Lang, and the Regular Attendant of Sanqi.

During the reign of Emperor Wei Wen, he once gave his relatives the right to kill people. Jiang Ji remonstrated after learning about it, so that Emperor Wei Wen withdrew the imperial edict, so as to prevent his ministers from domineering because of gaining power.

When Wei State was fighting against Wu State, the general rushed forward and was almost annihilated by the Wu army. Because Jiang Ji advised Wei Mingdi in time to send troops, this saved the Wei army from being annihilated by the entire army.

After that, Emperor Wei Ming centralized and monopolized power, which made many ministers hold great power. If it were not for Jiang Ji's advice, there might be another turmoil in the end of Han Dynasty.

Emperor Ming of the Later Wei Dynasty issued an imperial edict to commend him.

The edict said: "The minister of the husband's bones is the battle of the master."Economical talent and civil and military, service and diligence, every military and state event, there are always memorials, loyalty and hard work, I am very strong.

In the future, when foreign wars were frequent, Emperor Wei Ming built his palace internally, and the people complained a lot, and the grain harvest failed year after year.

Jiang Ji went to the Shu again to explain the pros and cons, so that Emperor Wei Ming no longer wasted his national power, indulged in sexual affairs, and concentrated on facing Wu and Shu.

Later generations call Jiang Ji a talented strategist, a rare man in the world.

He made repeated admonitions to prevent the monarch from indulging in pleasure, and made many battles to plan for victory. After Wei Guo, he was still the strongest in the Three Kingdoms, and Jiang Ji had a contribution. 】

The shame-monger leaves in shame.

The rest of the gifted scholars and beauties have not come back to their senses.

What Jiang Ji did will definitely be recorded in the annals of history and passed down through the ages.

This is also what these talented people yearn for.

In the end, I don't know who said, "As expected of Jiang Zitong! The minister of bones is worthy of his name."

Still Hefei.

"it is good!"

"it is good!"

"What a loyal minister!"

Cao Cao said three good words in a row, and he said: "Now I don't want you to be the prefect of Danyang, why don't you just become the prime minister of the country?"

Xiangguo Changshi is also the secretary of the prime minister, with great authority, because the prime minister is the head of all officials, and the secretary of the prime minister is naturally not a small official.

Cao Cao sent an invitation, which is undoubtedly a further opportunity, and the prime minister Shi ranks a thousand stones, that is, a monthly salary of eighty dendrobium.

And now he is the governor, and he is still majestic, but Zhilu is only a hundred stones, which is ten times worse.

Jiang Jixin said that he is definitely not greedy for money.

After weighing it, he immediately knelt down and said, "Thank you, Prime Minister!"

……

Chapter 148 Concrete

The streamer entered the soldier's body.

He was very happy, bowed down to Cao Cao and said, "Thank you, Prime Minister, thank you, Prime Minister!"

When the streamer completely dissipated, he felt something extra in his head.

"Prime Minister, the reward I got is the knowledge of making concrete." The soldier said.

------------

"Concrete, what's that? A kind of soil?"

"What's the use of making clay? Burning pottery figurines?"

Everyone was disappointed to hear what was called concrete.

Just by the name, you know it's not a good thing.

Cao Cao didn't believe that the reward for answering the questions would be useless, so he asked, "What's the use of this concrete?"

The soldier replied: "Concrete is inseparable from the manufacture of all buildings. It can serve as glutinous rice and will not be eaten by ants."

Glutinous rice is the adhesive of today's buildings. I heard that the Qin Great Wall is made of glutinous rice.

"Not only that, after the concrete solidifies, it is as hard as a stone, and it is the best choice for making a city wall. Even a slingshot cannot be smashed down."

Cao Cao's eyes lit up. If it is true what the soldier said, this thing called concrete has a bright future.

Why is the catapult a siege weapon?

Can stones alone knock down city walls?

This is the view of future generations.

Today's city walls will really be smashed down by stones, because they are basically rammed earth walls. The so-called Qin bricks and Han tiles appeared in the Warring States period.

But the firing of bricks is definitely not easy, and they are basically used in major buildings, such as the Efang Palace, rather than city walls.

Only a small part of the Qin Great Wall is made of bricks, and the rest are made of stone and rammed earth.

Until the Tang and Song Dynasties, Chang'an's imperial city and palace walls were all rammed earth walls, and the masonry walls seen by later generations were basically built in the Ming Dynasty.

It also allowed the Ming Great Wall to stand for hundreds of years and remain majestic.

The city walls of Hefei are undoubtedly rammed earth walls, not only that, even the houses are also rammed earth.

"Concrete can build a house to more than five floors, even Qin bricks can't compare." The soldier said.

Cao Cao has already thought of the application scenarios of concrete, but he still doesn't quite believe that there is such a thing in the world.

Maybe the soldiers were exaggerating.

He asked again: "Can you make this concrete now?"

The soldier shook his head and said, "Cement needs to be produced before concrete can be produced. Cement production is a relatively complicated process that requires limestone."

"Limestone can only be mined in limestone mines."

Everyone sighed, it turns out that the concrete is not meant to be available.

Yes, of course such a magical thing.

At this time Jiang Ji asked: "Can you tell me more about this limestone?"

"If I can distinguish the limestone now, I can tell it at a glance. It is a kind of off-white stone, and the color is like the sky that is about to rain."

The specific soldiers can't express clearly, or even if they express it, others may not understand it.

But Jiang Ji thought for a while and said: "If you want to talk about gray stones, I know a place in Hefei."

"White Horse Mountain in Feidong, the whole mountain is gray and white, hence the name."

The soldier was stunned for a moment, and said: "Then it is really possible that it is a limestone mine. If there are stones from that place, maybe I can distinguish it."

Baima Mountain in Feidong is still tens of miles away from Hefei City. Of course, it is impossible to mine ore and come back.

But it's not impossible, as long as you bypass the Jiangdong Army and send cavalry to dig a piece back, you will know.

But Jiang Ji said: "Why bother, in fact, I often collect some strange stones, and I brought some back. They are at my home, and I asked someone to fetch them."

Jiang Jixin said that he definitely didn't think the stone was beautiful and brought it back because he could sell it for a good price.

It didn't take long for the stone to be retrieved.

It was a snow-white stone with a touch of green, compared to stone, it was more like a crystal.

Shining in the sun, like stars twinkling, very beautiful.

"Is this limestone?" Xu Huang stepped forward to observe carefully and asked.

The soldier shook his head and said, "It's not. It should be dolomite. Limestone is a stone. It will only be gray, and there will be no other colors."

"After this dolomite is contaminated with other minerals, it will appear in other colors."

Everyone was disappointed.

But the soldier said, "Dolomite is usually together with limestone, so it is really possible that Baima Mountain has limestone."

He cupped his hands at Cao Cao and said, "Prime Minister, if there is concrete, the city walls can become indestructible and the buildings can be built higher. If there is limestone in Baima Mountain, then please ask the Prime Minister to order it to be mined."

Cao Cao has always known people to use them well. If this concrete can really be compared to stone, then it has a wide range of applications.

Of course he will not be stingy.

"I sent people to mine a thousand catties of limestone and came back. If you let me see the finished concrete, I will think about it later."

Soldiers are confident, no one can resist the temptation of concrete.

He couldn't wait any longer, and said, "Obey!"
