Lu Yu scratched his head. How could he think about Sister Zhaoji's "enlightenment" when it was so urgent?
Sister Zhao Ji in her prime... now is the time to grow.
Besides...after Lu Yu's "careful" care, including all the arrangements of crucian carp soup, chicken feet, and avocado, the originally ordinary pair of A's big and small ones showed their sharp points... grew into a pair of B's.
impulse.
Enlightenment will have to wait until Sister Zhao Ji grows up quickly...
Thinking of this, Lu Yu's unsatisfactory saliva flowed from the corner of his eyes, and there were four big words on his cheek - "Heart yearning for it."
Of course, the little lotus has just revealed its sharp horns, and the dragonfly can't stand on it yet!
"Brother Yu? What are you thinking about? You're all in a daze..." Cai Zhaoji didn't know Lu Yu's thoughts, so she asked...
Uh... Lu Yu glanced at Sister Zhao Ji's thing out of the corner of his eye. He was still a little disappointed. It was still far from the ideal size.
Of course, this look of "disappointment" cannot escape Cai Zhaoji's eyes.
She spoke again...
"Is it possible? This forging of iron has always failed. Is Brother Yu's mood also affected?"
That’s right…
Lu Yu nodded quickly. Lu Yu was worried about the process of forging iron and steel and Sister Zhao Ji forging that!
"Sister Zhaoji, I'm...okay! It's just..."
Lu Yu raised his eyes again and glanced at Cai Zhaoji... then turned his eyes to the iron furnace and said helplessly.
"If we continue to forge like this, the iron will be exhausted... The iron iron now has a price but no market. Except for the fact that Mr. Cao still has some in stock, it is difficult to buy it on the market!"
"Isn't the iron iron already hard enough? Why do you need to forge it again? Is it possible... that something harder than the iron iron can be forged?" Cai Zhaoji then asked...
Having read thousands of books, Cai Zhaoji knew a lot about weapons. During the Spring and Autumn Period, the Warring States Period, and even during the Qin Dynasty, bronze weapons were still the main weapons.
During the Chu-Han struggle for hegemony, iron weapons gradually appeared. It was not until the Han Dynasty King Mang rebelled that iron weapons completely replaced bronze weapons...
In Cai Zhaoji's view, weapons forged from iron can fully represent the most advanced productivity...
Besides gold, is there anything stronger than iron? Cai Zhaoji was confused. She couldn't figure out what brother Lu Yu was pursuing?
It’s no wonder she thinks so. How did Cai Zhaoji know that men often have much higher requirements for hardness than women? This is true for forged steel, and the same is true for other things!
"It's not just harder than iron..." Lu Yu curled his lips. "If it can be forged successfully, it will be enough to cut stone and metal, and cut iron like mud!"
Hmm... Cai Zhaoji paused. Is there really such a hard thing in this world? For a moment, she was a little curious.
"Alas..." Lu Yu sighed helplessly. "It's a pity. If the forging is successful, I'm afraid I'll need a lot of iron. If I ask Mr. Cao for... such precious iron, I'm afraid that Mr. Cao won't give it.
."
In short, Lu Yu shook his head, the great cause of steel forging has encountered difficulties.
Just then...
"Hahaha, tell me what I, Cao Cao, am reluctant to give!"
"Whatever you want, as long as I, Cao Cao, have it, take it all!"
A hearty laugh came, followed by brisk footsteps and a hearty voice... This extremely magical laughter and voice were not Cao Cao? Who else could it be?
Lu Yu and Cai Zhaoji hurriedly turned around, only to see Cao Cao and Cao Ren walking towards them.
"I don't want my brother to be free today..." Cai Zhaoji spoke first, still polite.
"Why...can't you come and see Xianmei if you don't have time? Come and see Xianmei's smart and clever brother? Hahaha..." Cao Cao replied, and then started laughing!
Cao Cao likes to laugh very much... As long as his father or relatives are not dead, he can always laugh... To a certain extent, he is an extremely optimistic person.
But, this stall today?
How could Lao Cao smile so brightly?
Lu Yu rolled his eyes and murmured in his heart... Come to think of it, Cao Song has escaped!
I just don’t know, was Cao Song rescued by Cao Ren? Or was he rescued by Dian Wei...
All in all, just save him... Lu Yu felt like he was breathing a sigh of relief!
According to records in ancient books and documents, Yanzhou under Cao Cao's rule once experienced a major crisis. Except for three cities and counties in Yanzhou, all of them were stolen by Lu Bu...
There are two fundamental reasons for this incident. One is the death of the famous scholar Bian Rang, which caused a lot of rifts between the Yanzhou clan and Cao Cao. The other is that during the conquest of Xuzhou by Cao Cao to avenge his father, his bones were exposed under the massacre. In the wild, there is no rooster crow for thousands of miles.
These two incidents made the Yanzhou clan particularly convinced that Cao Cao was not the master of the Ming Dynasty, so they, led by Zhang Miao, the prefect of Chenliu, joined forces with Lu Bu to destroy Cao Cao's base camp...
But now, as soon as "Bian Rang" is alive, he is sent to the court;
Secondly, Cao Song is not dead, but Cao De is alive. For Lao Cao, the loss of Langya County this time... is nothing more than the loss of some gold and silver jewelry, and the death of some unimportant family members. Naturally, revenge is still necessary, but There is no need to massacre the city!
As long as the city is not massacred, it will be much easier to capture Xuzhou, and there will be no big trouble in Yanzhou in the rear!
On a more minor note, the safety of Lu Yu and Sister Zhao Ji is guaranteed;
On a larger scale, if Cao Cao expands his territory, his territory plan can proceed smoothly, killing two birds with one stone!
Of course, in Lu Yu's opinion...it would be best if Dian Wei saved him, so that Lao Cao would owe him a huge favor!
"I heard from Wen Lie that your boy seems to be addicted to forging recently?"
Cao Cao spoke. He deliberately did not mention his father's rescue, but asked Lu Yu about what he had been busy with recently.
"Mr. Cao, this... can only be considered an experiment at most!..." Lu Yu blurted out subconsciously.
"Experiment?" Cao Cao asked...
Lu Yu scratched his head. It seemed that the word "experiment" was still too fashionable for Old Cao to understand! "Mr. Cao... just tried forging many times and got the correct result, but so far it seems... not even close!"
"How much difference?" Cao Cao would tell Cao Xiu every few days.
How could he not know that Lu Yu was recently trying to forge a material ten times stiffer than iron?
It's just that... the forging process is a bit weird. The iron is melted into a liquid state, and then the liquid iron is poured into the original iron.
This forging method is really unbelievable. After all, Cao Cao also thought it was too mysterious, and most of these expensive iron and steel would be wasted.
That's why Cao Cao asked such a question.
At this time, Lu Yu rolled his eyes... and answered truthfully. "It's bad... It's hard to estimate. It requires a lot of attempts, and it may fail in the end... and you'll get nothing!"
In front of Cao Cao, Lu Yu was unwilling to tell lies or draw a big picture...
Besides, he only knew the steps for forging steel, but the actual operation was by no means as simple as it seemed in theory. The temperature of the fire and the timing of pouring the wrought iron into the pig iron were all very important. An extremely small difference might be enough. Affects the entire forged steel situation!
…
Hiss... it is possible to fail and gain nothing?
Cao Cao's eyes rolled, and he was also evaluating this sentence in his heart.
You know, iron is a strategic material. Apart from war horses, the only thing that money can't get these days is iron. Taking a warehouse of iron and letting Lu Yu "do experiments" made Cao Cao murmur in his heart!
"but…"
At this moment, Lu Yu's voice came out one after another. It was this sentence that made Cao Cao's eyes suddenly become firm.
