The riding and shooting problem that made Huangfu Song helpless was solved by Cao Cao.

The three armies were about to go to war, and the arsenals around Luoyang were rushing to make iron stirrups day and night. Fortunately, the iron stirrups were made relatively simple in their workmanship, and Cao Cao personally supervised the matter. On the evening of the fourth day, nearly 10,000 were rushed to produce.

Liu Sandao was sweating profusely. After two days, the iron stirrup was forged. But when he excitedly gave Cao Cao the drawings and finished products, he was surprised to find that this thing had been used in the military camp.

I was deeply surprised at the moment. Could it be that the manufacturing drawings of the iron stirrup were leaked? They were stolen?

After a closer look, I realized that it was the little boy’s father Cao Cao who made such a thing.

Well…

This is a bit meaningful.

Obviously, it cannot be said that it was stealing, it should be said that it was stealing. Scholars, no... what is the case with father and son?

Fortunately, after changing his mood, Liu Sandao returned to his forging steel career. After thousands of iron consumption, he was surprised to find two pieces of iron that were most suitable.

Different from other irons, when they are forged into pig iron and cooked iron, they are compatible. Liu Sandao was surprised to find that the strength of these two irons is far greater than that of others.

He obviously doesn't know the scientific principles of co2co2 in the chemical formula...

I don’t know that the ratio of sulfur (s) in ordinary c (iron) contains, and I don’t know that so2 (ignition) = so2 (sulphur dioxide). The so-called so2 will greatly reduce the hardness of steel!

By chance, Liu Sandao found two pieces of pig iron with extremely low sulfur content, which can truly forge iron with refined steel that is as sharp as mud.

this?

For those who like forging, a good piece of iron is enough to make him excited!

For two days, Liu Sandao kept completing each forging process carefully, and then forged it carefully, repeatedly beat it, and finally forged two swords.

"call…"

After breathing a long breath, Liu Sandao wiped the sweat from his head and looked at the two swords in front of him, feeling satisfied. In his opinion, perhaps, he could never find any iron that could forge such fine steel, nor would there be any steel that could forge such two swords as sharp as mud!

"It's finally successful!"

Liu Sandao felt relieved.

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

It is said to be forged steel, but in fact it is to use gold to smelter into a furnace, and it is converted into Wuzhu coins. After half a month of rushing, it has been spent tens of millions of dollars...

But the results were very little. It would not be an exaggeration to say that these tens of millions were completely wasted.

The most terrifying thing is that young master Cao Shuo did not scold him at all, but instead, in order to support him, he kept delivering gold and a good iron purchased. He even sent a cow early in the morning to help him replenish his body!

This...apart from being rich and willful and not treating money as a taste of money, the only thing left is absolute trust in Liu Sandao.

But Liu Sandao couldn't get over it!

The Cao family is so rich? The young master Cao Shuo can make money? Can he withstand the squandering of Liu Sandao like this?

Liu Sandao felt distressed every day, as if he was sitting on pins and needles!

Now it's OK!

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

Select the most suitable iron from tens of millions of dollars of iron, and then use a lot of experiments to sharpen the forging steel skills, repeatedly forging, repeatedly polishing, and harnessing, and then the sword came out!

It’s not a boast. Only the forging man Liu Sandao would know the power of these two swords. It would be said that they would cut iron like mud, cut silver and break gold, so there would be no problem.

"oops…"

Liu Sandao seemed to have thought of something suddenly.

"You have to tell the young master this news quickly and make him happy."

As he spoke, Liu Sandao carefully put away the sword forged by hundreds of refined steel and quickly walked towards the young master Cao Shuo's room...

...

Cao Mansion, Cao Shuo’s Pavilion!

Diao Xiuer walked over with fruits and snacks.

And in front of her, Cao Shu and Liu Bian seemed to be playing with wooden cards!

"Xiao Shuo, you are wrong! How can Yi suppress Jiu? You don't understand this common sense of arithmetic in pediatrics?" Liu Bian held a wooden card in his hand... and muttered something in his mouth. "You are blowing me up! The cards must not be played like this!"

"Calm down!" Cao Shu waved his hand. "The rules have told you before that except for the two cards of "king" and "last", one is the biggest. If you have four cards, you can blow me up!"

"Then, four four!" Liu Bian took out four pieces from the wooden sign.

"I'll give four eights!" Cao Shuo was calm.

"You..." Liu Bian spread the wooden card in his hand, "I lost, I lost, I lost again!"

Today is a rest day for the Imperial College.

Cao Shu was originally thinking about teaching Liu Bian to point out, "Is that true, that's what it means."

After all, Queen He entrusted this naughty child to herself, and she was half of his father!

As the saying goes, the son is not a godfather’s fault, Cao Shu is moral, and we should not be a waste of this "father". At least, we cannot let Liu Bian fail the grades in Taixue, right?

But just as long as he mentioned his studies, Liu Bian was very resistant. He seemed to have a natural hatred for "poetry, songs and essays". Whenever he heard the four words connected in a string, he was overwhelmed, upset, and irritable, and wanted to demolish the house. He was like a piglet that had not been castrated!

There was no other way, Cao Shu could only force him to learn by replacing it.

So Cao Shu made a deck of cards and a wooden card. It was actually very simple. Each wooden card was marked with black, red, plum, and square, and then wrote capital numbers, "one" to "nine", plus the two supreme cards, king and queen, in this way, a simple playing card with a number of nine is completed.

Liu Bian was not interested in his studies, but was very curious about this thing.

After a while, I started to pester Cao Shu and teach him how to play cards, and even became addicted! Cao Shu set the rules, whoever loses, he has to memorize an article!

Liu Bian agreed immediately, but he lost five or six games in a row, and he was drunk. Cao Shu knew the routine very well! Why did his card be? Cao Shu knew everything? This was embarrassing!

The naive Liu Bian didn't realize it yet.

There are only a few cards for two people. What are the cards in their hands and what cards in the other party are? Is it clear at a glance?

If Cao Shu wanted to say hello urgently before traveling through time, "Come on, pour a cappuccino for Prince Defender!"

...

"No, no! You are unfair."

Liu Bian was a little furious. This card is fun, the key is that he has never won!

"Prince Bian lost again, I owe me seven articles now!" Cao Shu spread his hands and acted as he shuffled the cards.

"Don't bear it!" Liu Bian turned his head in anger.

"If you don't bear it, I won't play with you." Cao Shu was unmoved. He knew that the prince was in a hurry and was wondering how to win a game, and how could he give up!

"That's it!" Liu Bian seemed to have thought of something. "Let Diao Xiu'er come and play together. The three of us will play, including Diao Xiu'er, whoever loses will have to memorize the article? You can't be bullied by me, a novice, right?"

"ah…"

Upon hearing this, Diao Xiu'er was shocked. "I don't understand the article!"

"If you don't understand, you can learn it! I don't understand it either!" Liu Bian suddenly found it interesting. He turned his head, "Xiao Shuo, tell me what are the ways for three people to play!"

"Yes!" Cao Shu smiled slightly. "But we agreed first. If you lose this time, you must recite it. You have to use your personality guarantee!"

"Chengchengcheng, I use my father's head to guarantee that as long as it is not the four-word 'fu', I can recite anything!" Liu Bian made his last stubbornness. Even if he died, he would not recite thefu, and did it...

Of course, Cao Shu vaguely felt that he did not seem to take his father's head seriously!

"Yes!" Cao Shu nodded and turned his eyes to Diao Xiu'er. "She'er stops standing, sit down!"

"Really? Do you really want to play?" Diao Xiu'er felt something was wrong. "Or, I'd better prepare tea fruits for the two young masters?"

"I let you play, just play? My father and mother are not here, what are you afraid of?" Liu Bian made a special place, and then urgently asked Cao Shu. "Our Saner? What are you playing!"

Cao Shu smiled slightly and covered all the small wooden signs. "Start the cards first, I will teach you how to play Landlord!"
