Three Kingdoms: I Have a Showdown, I Am Cao Cao

Of course, there are still a lot of coincidences in the success of the blacksmith shop pouring steel.

Here, except for Yi Xiaotian, everyone will definitely not consider the scientific principle of C+o2=Co2 in chemical elements.

Not to mention that Fe (iron) contains S (sulfur);

I don't even know that once it is ignited and reaches the boiling point, the chemical reaction of S+o2=So2 (sulfur dioxide) will occur.

It is precisely this so-called sulfur dioxide, which penetrates into the iron, which can dissolve the impurities and make the iron become harder steel.

As for the principles of SP (hot brittleness and cold brittleness) that are also involved, as well as solid solution strengthening, secondary strengthening is more complicated.

However, none of this matters anymore.

With the knowledge in his mind, Yi Xiaotian really used the hands of Lu Lingqi and a group of craftsmen to put the steel pouring method into practice.

Suddenly, he was very grateful... The nine-year compulsory education he had received before the time traveled. Sure enough, compulsory education is very good and powerful!

Calm on the surface, ecstasy inside.

Yi Xiaotian knew that when Gang appeared in this era, there was no absolute fairness in the battlefield of cold weapons...

It's as if steel is ten times harder than iron, and the Iron Legion is against the Steel Legion, it's like an ant's day's elephant - strength can't be used!

Yi Xiaotian felt disappointed for a while, how much money this thing could make, he didn't even dare to think about it.

But at this time.

Brother Yi?what is this?Are you all ecstatic?

A crisp and familiar voice came one after another, Yi Xiaotian looked back, wasn't the one standing behind him, brother lie?Who else could it be?

When did brother lie come to the blacksmith shop?

You are a genius, remember for a second:

Chapter [-] Diversion of water and pouring water, fire and water are ruthless, the sky in Xuzhou has changed

Concealed brother?Why didn't you say hello when you came?

I also just arrived, and I saw Brother Yi playing with that little girl, how can I bear to bother?

Facing Yi Xiaotian's questioning, Cao Cao laughed and joked...

Yi Xiaotian gave a wry smile, which was a response... Where did he play with Lu Lingqi, it was clear that this girl was disobedient and taught her a hard lesson!

correct.After joking, Cao Cao pointed to the iron case.Brother Yi?Are you refining steel?Can refined steel be made artificially?It turns out... that's the reason why Brother Yi planned to go to the city of Picheng?

After three questions in a row, Cao Cao suddenly became very interested in Yi Xiaotian's refining of iron.

It's just steel, and it can't be called a hundred refined steel.

Yi Xiaotian didn't hide it either.It's not a finished product yet, but it's a complete improvement to be able to forge it. It's considered to have mastered the method of forging steel. The main reason is that there is no good quality iron in the market. It's almost meaningless.otherwise…

Yi Xiaotian originally wanted to brag, looking forward to how invincible the blade forged with hundred-refined steel is.

But he finally stopped.

The problem now is not the study of the method of pouring steel, but the refining of real guns and live ammunition.

But after all, it is subject to the quality of iron and iron on the market... From this point of view, the best iron iron in Xiapi City is particularly important.

Thinking of this, Yi Xiaotian recalled something.

By the way, didn't Brother Hide accompany Cao Cao on his expedition to Xiapi this time?How about it?Has Xiapi City been captured?

Yi Xiaotian was thinking about the iron in Xiapi City.

Although Cao Cao was still very curious about this fine steel, since Brother Yi mentioned something serious, Cao Cao simply moved the topic here first.

Thinking of the high walls and thick walls of Xiapi City, Cao Cao couldn't help shaking his head.Alas, since Brother Yi had anticipated it in advance, why bother making fun of me?Now Cao Cao has encountered a big problem, but this problem, I and all the advisors are also at a loss.

Is it the problem of Xiapi city defense?Yi Xiaotian asked directly.

Cao Cao nodded and remained silent...

Haha... I never thought about it, Yi Xiaotian laughed out loud.I thought that my brother should be here in the past few days...

Yi Xiaotian patted the dust on his body and explained to Lu Lingqi a few words about the forging of steel in the blacksmith's shop. He immediately raised his hand and greeted Brother Dao, let's go to the wine shop and chat!

Yi Xiaotian winked at Cao Cao while talking...

Cao Cao is very good at observing words and expressions. From the corner of his glance at Lu Lingqi, Cao Cao can see that Yi Xiaotian cares about Lu Lingqi very much, and does not want Lu Lingqi to know too much about Lu Bu.

Well, I was just about to have a drink with Brother Yi!

Cao Cao replied with a smile... This is also a face-to-face word, in order to dispel Lu Lingqi's vigilance. Now, there is no room for front-line battles, so he doesn't have the heart to drink!

Not long after, Yi Xiaotian entered the restaurant with Cao Cao and Cao Ren...

Looking at the figures they were leaving, Lu Lingqi narrowed her eyes slightly, as if she had a premonition that something ominous was about to happen.

Well, what is Xiapi City?Father...he...me, let me eavesdrop!

Lu Lingqi's pink fist clenched slightly, and she trotted towards the restaurant.

There is a liquor store, inside the Accord.

Cao Cao deliberately checked the doors and windows around him and confirmed that no one was there before he said.Brother Yi, that girl Lu Lingqi didn't come.Now you can safely tell the method of breaking down the city of Xiapi!

Cao Cao's tone was low, but his tone was extremely rapid.

Yi Xiaotian nodded, but he was not busy talking.

Instead, the tea cups, wine bowls and chopsticks on the table were placed one by one, and the terrain, topography and situation around Xiapi City were simply presented as much as possible.

Concealed brother, look...

Yi Xiaotian pointed to the plate in the middle of the table, this was Xiapi City... and Cao Jun was stationed outside the city.

Referring to Cao Jun, Yi Xiaotian pointed to the tea cup not far from the plate.

Cao Cao listened and watched carefully. Brother Yi seemed to be very good at explaining with a sand table.

Concealed brother, look here again.

Yi Xiaotian pointed to the corner of the table, where a few chopsticks were hastily placed, but Cao Cao didn't know, what did these chopsticks refer to?

Brother Yi, is this?Cao Cao asked curiously.

These chopsticks are Sishui River, Yishui River... Yi Xiaotian explained...

When Brother Yi said this, Cao Cao was amused. Even on the sand table at the dining table, how could he use chopsticks to be a river?

Haha... Brother Yi, this metaphor is funny, funny!Cao Cao said with a smile.

More interesting is yet to come.Yi Xiaotian gently moved the chopsticks... and then changed the direction of a series of chopsticks, one by one connected to Xiapi City.

At first, Cao Cao didn't feel anything about this move...

But soon, Cao Cao's forehead swish, as if electrocuted.

Bang saw Cao Cao fiercely slap the case, and then suddenly stood up... suddenly realized.Brother Yi, you are going to flood Xiapi!

That's right, since Yi Xiaotian moved his chopsticks, Cao Cao realized that Brother Yi planned to use the water of the Sishui River and Yishui River to make a fuss, but he never imagined that Brother Yi planned to direct the water to the Xiapi…

To know…

The terrain of Xiapi City is low on three sides and high on the other side. If the method of digging trenches is used, the Si River and Yi River can become floods in one fell swoop, and the city will be flooded back down... At that time.

Cao Cao looked horrified, but Yi Xiaotian was still calm...

As he moved the tea cup representing Cao Jun to a higher place, he opened his mouth and said.Don't be surprised, the reason why I didn't directly reveal the mystery of breaking Xiapi City last time was because of specific problems that must be analyzed in detail.

Now that spring has begun, the ice on the surface of the Sishui River and Yishui River has melted. In addition, every spring in Xiapi City, it is the rainy season, and the water level will naturally rise at this time.

If Cao Jun dug deep trenches around Xiapi City at this time to cause floods to pour down... Wouldn't Xiapi City be completely flooded?It is said that fire and water are ruthless. When the time comes, Cao Jun, who is at a high place, sees the appearance of Lv Bu's three armies like a stagnant dog... How can each soldier not have a high morale?Eager to try?It is estimated that they are all scrambling to row a boat to shoot down a water dog, right?

Yi Xiaotian said it lightly, but this plan is full of viciousness...

Diversion and pouring water, water and fire are ruthless!

Not to mention that Lu Bu was just a mere god of war, even if he descended from the earth, how could he stop this turbulent flood from raging in the sky!

Brother Yi, this calculation...

Lu Bu is about to be destroyed.

Brother Yi, your plan is ruthless!Cao Cao sighed.But, to be honest, I really like it.

A word blurted out.

Ha ha ha ha…

Cao Cao laughed heartily.

For three days and three nights, I ran from Xiapi City to this Youjian Villa, and ran for three days and three nights, killing four fast horses... Even Cao Cao's whole body was exhausted.

Still, it's all worth it...

The mountain torrent roared and was unstoppable. Brother Yi's plan turned the rivers and seas at the same time, but also changed Xuzhou completely.

Thinking of this, Cao Cao surrendered, and planned to say goodbye... The front-line soldiers were still waiting for his plan to break the city.

But at this moment, Yi Xiaotian's casual words made Cao Cao's heart tremble.

Concealed brother?Have you thought about it?If the city is broken, what will Cao Cao do with Lu Bu?How to deal with Chen Gong?How to recruit Lu Bu's generals?

call out…

Cao Cao was startled.

He was preoccupied with how to break the city, a question he had never thought about.

But it was suggested by Brother Yi, just thinking about it... Incredible, this is a big problem, a big problem that affects the whole body!

You are a genius, remember for a second:

Chapter [-]: Unparalleled Lu Bu, should I kill or not?

Lu Bu?To kill or not to kill?

Chen Gong?To kill or not to kill?

Gao Shun, Zhang Liao, and Zang Ba are all loyal and brave people, and there are eight strong generals... These are all immediate combat power, how to recruit them?

These problems one by one are like stinging poisonous thorns one after another.

In case any part is not handled properly, and the hearts of the people are cold, this military general, Lu Bu's surrender, will all be buried in vain?
