The problem of riding and archery that made Huangfu Song helpless was perfectly solved by Cao Cao.

The three armies are about to go on the march, and the arsenals around Luoyang are rushing to make iron stirrups day and night, thanks to the relatively simple workmanship of this iron stirrups, pouring the power of the entire Central Plains, and Cao Cao personally supervising this matter, nearly 10,000 pieces have been produced on the evening of the fourth day.

Liu Sandao was also sweating like rain here, and it took two days to forge the iron stirrup, but when he excitedly sent the drawings and finished products to Cao Cao, he was surprised to find that this thing had been used in the military camp.

Surprised, isn't it? The manufacturing drawings of this iron stirrup were leaked? Stolen?

After a closer inquiry, I found out, it turned out? It's the little boy's father, Cao Cao, who made up such a thing.

Belch...

That's a bit of a point.

Obviously, it can't be said to be stealing, it should be said to be plagiarism, reader, ah no... What is there to steal from the fathers and sons?

Fortunately, after a change of mood, Liu Sandao returned to his forging steel business, and after thousands of iron consumption, he was surprised to find two pieces of iron that were most suitable.

Different from other irons, in the process of forging them into pig iron and wrought iron, the two are compatible, and Liu Sandao was surprised to find that these two pieces of iron are far stronger than others.

He obviously didn't know the scientific principle of C+O2+CO2 in the chemical formula...

I don't know that the proportion of sulfur (S) in ordinary C (iron) is not known, and I don't know that S + O2 (ignition) = SO2 (sulfur dioxide), the so-called SO2, will greatly reduce the hardness of steel!

By mistake, Liu Sandao found two pieces of pig iron with a very low sulfur content, which can be forged in a real sense to forge iron iron that is like clay and refined steel.

This?

For those who love to forge, a piece of fine iron is enough to excite him!

For two days in a row, Liu Sandao did not stop for a moment, carefully completed each steel forging process, and then forged it carefully, hammered it repeatedly, and finally forged two swords.

"Whew..."

With a long exhalation, Liu Sandao wiped the sweat on his head, looked at the double swords in front of him, and felt a sense of satisfaction in his heart. In his opinion, perhaps, there will be no more iron that can forge such fine steel, and there will never be another steel that can forge such two swords of iron as clay!

"It's finally worked!"

Liu Sandao was relieved.

During this time, he seemed to be calm on the surface, but in fact, he was under a lot of pressure in his heart.

It is said that it is forged steel, but in fact, it is to take gold and smelt it into a furnace, convert it into five baht coins, and it has been smashed into tens of millions of dollars in a hasty half a month...

But the effect is very small, and it is not too much to say that these tens of millions are completely lost.

The most terrible thing is that instead of scolding him in the slightest, in order to support him, Cao Shuo sent a steady stream of gold, the best iron he bought, and even sent a cow early in the morning to make up for his body!

This... Except for some rich and capricious people who don't treat money as money, the only thing left is absolute trust in Liu Sandao.

But Liu Sandao can't get over it in his heart!

Is the Cao family richer again? Cao Shuo's little son can make money again? Can he afford Liu Sandao's squandering like this?

Liu Sandao feels distressed every day, like sitting on pins and needles!

It's good now!

Two peerless swords, this is the result, the brilliant result.

Select the most suitable iron from tens of millions of iron, and then through a large number of tests to sharpen the forging steel skills, repeatedly forging, repeated grinding, thousands of tempering, the sword is out of the mountain!

It's not a boast, only Liu Sandao, the person who forged, will know how powerful these two swords are, and there will be no problem if they say that they are cutting iron like mud and breaking silver and gold.

"Oops..."

Liu Sandao seemed to think of something suddenly.

"You have to tell the little boy the news quickly, and make him happy."

As he spoke, Liu Sandao carefully put away the sword forged from a hundred refined steels, and walked quickly towards the room of the little boy Cao Shuo...

……

Cao Mansion, Cao Shuo's Pavilion!

Diao Xiuer came with fruits and snacks.

And in front of her, Cao Shuo and Liu Wei seem to be in... Playing wooden cards!

"Xiao Shuo, you're not right! How can one hold down nine? You don't understand the arithmetic knowledge of this pediatrics? "Liu Wei is holding a wooden sign in his hand... He muttered something in his mouth. "You're blowing me! That's not how cards are played! ”

"Calm down!" Cao Shuo waved his hand. "The rules told you before, in addition to the two cards of 'king' and 'queen', one is the largest, if you have four of the same, you can up!"

"That, four four!" Liu Wei took out four cards from the wooden cards.

"I'm out of four eights!" Cao Shuo was not shocked.

"You..."Liu Wei spread the wooden card in his hand, "Lost, lost, lost again!" ”

Today is a rest day for Taixue.

Cao Shuo originally thought about teaching Liu to argue "the, hu, who, also".

Anyway, Queen He entrusted this bear child to herself, and she can be regarded as half of his father!

As the saying goes, the son does not teach the father's fault, Cao Shuo is moral, this "father" is not in vain, at least, we can't let Liu Weitai fail his grades, right?

But as long as it is mentioned in his studies, Liu Wei is very resistant, he seems to be born with hatred for "poetry and songs", but whenever he hears a string of four words, his head is big, upset, irritable, and he can't wait to tear down the house, just like a pig that has not been castrated!

There was no way, Cao Shuo could only force him to study by replacement.

So, Cao Shuo made a deck of cards, a pair of wooden cards, in fact, it is very simple, each wooden card is marked on the black, red, plum, square, and then write the capitalized number, "one" to "nine", plus the supreme two cards, the king and the queen, in this way, a simple playing card within the number nine is completed.

Liu Wei is not interested in his studies, but he is very curious about this thing.

came and went, and began to pester Cao Shuo to teach him to play cards, and even became addicted! Cao Shuo set the rules, if anyone loses, he has to memorize an article!

Liu Wei immediately agreed, but he lost five or six games in a row, and he was also drunk, Cao Shuo knows the routine very well! Why what are your cards? Cao Shuo knows everything? It's embarrassing!

The naïve Liu Wei has not yet realized it.

Two-person poker, just a few cards, what are the cards in their hands, what are the cards in the opponent's hands, at a glance?

If it was before the crossing, Cao Shuo wanted to say hello urgently. "Here, pour a cappuccino for the prince!"

……

"No, no! You're not fair. ”

Liu Wei is a little angry, this card is fun, the key is that he has not won!

"The prince of debate has lost again, and now he owes me seven articles!" As soon as Cao Shuo spread his hands, he shuffled the cards.

"Don't carry it!" Liu Wei turned his head angrily.

"Don't carry it? I won't play with you. Cao Shuo was unmoved, he knew that this prince was on the rise, and he was thinking about how to win a game, how could he stop!

"That's it!" Liu Wei seemed to have thought of something. "Let Diao Xiu'er also play together, the three of us will play, including Diao Xiu'er, whoever loses will have to memorize the article? You can't let me be a newbie, right? ”

"Ahh

Hearing this, Diao Xiu'er was taken aback. "Slaves don't understand articles!"

"I don't understand, I can learn! This prince doesn't understand either! Liu Wei suddenly felt interesting. He turned his head, "Xiao Shuo, tell me about it?" What is the way to play with three people! ”

"Yes!" Cao Shuo smiled slightly. "But let's say it first, if you lose this time, you have to carry it, and you have to use your personality to vouch!"

"Cheng Chengcheng, I use my father's head as a guarantee, as long as it's not a four-word 'fu', let me carry anything!" Liu Wei made the last stubbornness, he didn't even die to carry the endowment, to do the endowment...

Of course, Cao Shuo vaguely felt that he didn't seem to take his father's head seriously!

"Yes!" Cao Shuo nodded, and his gaze turned to Diao Xiu'er. "Xiu'er, don't stand, sit down!"

"Really? Do you really want to play? "Diao Xiu'er thinks something is wrong." Otherwise, the slave maid still prepares tea and fruit for the two sons, right? ”

"This prince asks you to play, and you play? The father and mother are not here, what are you afraid of? Liu Wei specially vacated a place, and then asked Cao Shuo urgently. Let's three? What to play! ”

Cao Shuo smiled slightly and covered all the small wooden cards. "Start the cards first, this one, I'll teach you to play the landlord!"
