It soon came to dawn the next day.
A sharp rooster crow instantly woke up Qi Rusong, who had been sleeping for a while while leaning on the chair. He jumped up from his seat and subconsciously pulled out the saber from his waist.
The sound of Cang Langlang's sharp knife immediately woke up Li Ke and Su Xun. They looked at Qi Rushong, obviously startled.
"What's wrong?" Su Xun asked in a panic.
After coming back to his senses, Qi Rusong reacted, quickly put away his sword, and said awkwardly: "No...it's okay, I just had a dream."
Suddenly, he seemed to have thought of something, and hurriedly asked: "By the way, what time is it now?"
Only then did Su Xun react. He quickly picked up the black gauze hat that fell on the ground and took a quick look outside: "Look at the sky, I'm afraid it's already Yin Shi!"
Hearing this, Qi Rusong's face suddenly tightened and he said hurriedly: "Hey, I just said I couldn't sleep, I couldn't sleep, why did I just fall asleep! No, I have to go to the city wall quickly to have a look!"
Li Ke also roughly estimated the time, and said to Su Xun: "Mr. Su, let's go and see if the city wall can be built successfully. We will find out later."
A quarter of an hour later, the three of them had arrived at the place where the city wall was being built.
At this time, the place has become busy again. Dozens of civilians are starting to build the second layer of stone walls. A steady stream of concrete has been mixed and is just waiting to be poured.
As soon as Qi Rusong arrived at the scene, he immediately asked a soldier: "How is it? What happened?"
The soldier didn't say anything, but pointed to the foundation of the city wall with a smile on his face, and motioned Qi Rusong to check it himself.
Qi Rusong looked confused and hurriedly walked to the foundation of the city wall that had been laid last night to check. Then he was surprised to find that the concrete slurry, which was gray-black and like mud last night, had completely solidified and showed a blue color. Gray color.
However, Qi Rusong didn't care. Instead, he directly pulled out his saber and stabbed straight into the solidified concrete.
To Qi Rushong, although the concrete is made of stone, it looks the same as mud.
If it is mud, even if it is solidified, you can easily penetrate it with a knife.
However, when Qi Rusong's sharp saber touched the concrete surface, it did not penetrate as easily as Qi Rusong thought. Instead, it was blocked, and two sparks even shot out from the tip of the knife.
Qi Rusong suddenly felt numbness in the tiger's mouth, and his eyes widened in shock.
After being stunned for a moment, Qi Rusong suddenly held his breath and concentrated again, then swung his saber fiercely and slashed towards the solidified concrete again.
"when……"
Accompanied by a crisp metal collision sound and a string of dazzling sparks, Qi Rushong's sharp saber was blocked by the concrete again.
Moreover, Qi Rusong was even more surprised to find that his sword had been slightly curled, but only a small white scratch was left on the concrete.
Even the touch that was returned to Qi Rushong just now was as if he had struck a hard rock with a knife.
"How... is this possible?" Qi Rusong looked at the small white mark he could only leave on the city wall, feeling surprised and happy in his heart.
He obviously saw it yesterday, but the concrete was still like mud. How come it had turned into hard stone just one night later?
But no matter what, there is one thing Qi Rushong firmly believes in.
That is, with such a city wall, not to mention the Khitans, even the most advanced Wei siege equipment can't get even half of it.
Thinking of this, Qi Rusong was overjoyed, and then quickly turned to look at Li Ke behind him, and said excitedly: "This city wall is feasible, Your Highness, this city wall is definitely feasible! With this city wall, the Khitans will no longer be able to do anything about it in the future. We’re gone!”
At this moment, Qi Rusong has even thought about how the entire city wall of Kunyang City will be rebuilt with this solid concrete in the future.
By that time, I'm afraid no one in the world will be able to break through Kunyang.
Su Xun on the side couldn't help but be slightly surprised after seeing Qi Rusong's exaggerated performance. Then he quickly took a weapon from the government servant and stabbed the concrete on the city wall twice.
But Qi Rusong, who was in his prime of life, could not destroy even half of the city wall with all his strength. How could he care about Su Xun's old age and frailty? The final result was that Su Xun's stab failed to leave even a trace. .
Suddenly, Su Xun was overwhelmed with excitement, and his hands were trembling slightly.
He originally thought that it was impossible to build the city wall, and the only thing they could do was to wait for the Khitan's butcher's knife.
But now, everything seems to be turning around, and it’s a huge turning point!
After all, even if the current city wall is said to be a copper wall and an iron wall, it is no exaggeration. It is not an exaggeration to say that its strength is ten times or a hundred times that of the rammed earth city wall in the past.
With such a city wall, even if the Khitans came, they would probably only be able to look at the city and sigh.
"Wonderful! How good!" Su Xun suddenly shouted excitedly, "Now, half of Kunyang City is defended."
In this era without bombs and cannons, it is not an exaggeration to say that the concrete city wall is an iron wall, but it is still too early to say that half of Kunyang City has been defended.
Li Ke knew this very well, not to mention that even one-third of the city wall had not been built yet. Even if the city wall was completed, it was still unclear whether it could block the Khitan cavalry in the end.
After all, Li Ke still doesn't know how many Khitans will come to kill them. In the end, their purpose is just to defeat the autumn wind, or to completely devour Kunyang City.
If it was just to beat the autumn wind, they would naturally leave when they find that the city wall has been repaired. But if they were aiming to completely capture Kunyang City, it would be hard to say.
Li Ke had seen the situation map of the entire Yanyun area before, and the location of Kunyang was wedged into the Khitan territory like a nail.
More than a hundred years ago, there was a commander in the Wei Dynasty. Using Kunyang as a springboard, he led a group of thousands of cavalry to raid hundreds of miles, and penetrated directly into the hinterland of the Khitan people with lightning speed.
Before the Khitan people could react, they directly destroyed the Khitan royal court. As a result, the Khitan people still looked at Kunyang like a needle for more than a hundred years and tried to pull him away several times.
Especially recently, the Khitans seemed to be taking action again, so Li Ke naturally did not dare to take it lightly.
He followed the gap in the city wall and couldn't help but look into the distance, thinking secretly in his heart: "I just don't know if my secret weapon will be able to scare the Khitans in the end."
