Emperor of the Tang Dynasty

"Everything has a limit," Lu Dongzan said. "I don't believe that this gray-white city wall has no limit.

"Furthermore, if you say that you are going to retreat, Your Majesty is definitely unwilling, but if you continue to repeat the siege of the city by the cloud ladder, then the Tang army must have the upper hand, and our army will not be able to succeed at all. "

Lu Dongzan's meaning is very clear, that is, on the whole, it is the most cost-effective to continue to use rushing vehicles to attack the city.

"...don't tell me, I'll do the same."

Songtsen Gampo snorted coldly and shouted: "The whole army listens to the order! If you can't hit ten times, then hit a hundred times! I don't believe that this city wall will never be broken! Keep hitting me!"

"Bam! Boom! Bam! Bam! Bam! Bam! Bam! Bam! Bam! Bam! Bam!"

The next moment, loud noises rose again and again, and the Tubo soldiers were sweating like rain, and they kept hitting the city walls and gates of Songzhou with their rams.

As time went by, the soldiers of Songzhou fell down one after another, changing countless people, and they did not know how many times they had hit the city walls and gates of Songzhou.

Seeing the sunset, Songtsan Gampo and Lu Dongzan looked at the outer wall of Songzhou, and they all showed a smile.

"Ha... as I said, it works!"

I saw that under a lot of impact, the concrete on the city wall of Songzhou was already full of cracks, and some even fell off!

With such a result, both Songtsan Gampo and Lu Dongzan were very satisfied. Lu Dongzan directly signaled his generals to withdraw their troops and continue to attack the city with chariots tomorrow!

"If this continues, within a few days, Songzhou will be destroyed!"

……

Compared with Songtsan Gampo and Lu Dongzan, who were full of confidence, Li Xiaogong, Niu Jinda and others were a little panicked.

That night, they found Li You in the tent where Zhisili and Liu Lan were housed. Li You was lighting a lamp to check the injuries of the two.

"Well...recovering very well, it seems that he should be completely out of danger."

After the inspection, Li You nodded with satisfaction. This scene also moved Liu Lan and his mind-set to the extreme.

After these few days of cultivation, they have gradually recovered. Although they can't move, at least they can maintain a clear consciousness for a long time.

So seeing Li You caring about them so responsibly, both Zhili and Liu Lan felt that the pain on their bodies was not so serious.

"Thank you, His Royal Highness."

Even Liu Lan, who has always been taciturn, expressed her sincere thanks.

When Li Xiaogong, Niu Jinda and other three people who came in saw this, they walked over quickly: "Your Highness, the big thing is bad!"

Originally, they didn't dare to speak out when they saw Li You checking Liu Lan and his schizophrenia, but now they quickly seized the opportunity to explain the situation roughly.

"You said the city wall is about to collapse?"

Li You raised his eyebrows when he heard it, and Liu Lan and Zhili's eyes widened on the hospital bed.

"What!? Isn't this terrible?"

"Help me up! I can't keep lying down like this!"

"Both of you, don't move," Li You unceremoniously pressed one of his hands down. "If the wound opens, I will have to deal with it again in a very troublesome manner."

"But……"

Liu Lan and Zhi Shili both had anxious expressions on their faces, but after the two strong men found that they had been lightly pressed by His Royal Highness, they were unable to exert any strength.

This kind of feeling is very strange. It's not because of violent suppression. Li You can't do this kind of thing to the wounded. It's because they feel that... no matter how hard they try, the force goes directly through His Royal Highness's hand and sinks into the sea. It's very mysterious. disappeared without a trace!

"It's nothing," Li You said lightly, "Who said the city wall is about to collapse? You seem to be full of cracks in the wall, but it's only the outermost layer. In fact, I don't know how much concrete was poured. The thickness of a meter!"

The thickness of the general rammed-earth city wall in today's era is about seven or eight meters. This is mainly because the hardness of the rammed-earth wall is very poor, and it can only be compensated by the thickness.

Although the outer wall of concrete poured by Li You is not so exaggerated, it is at least several meters thick. In terms of strength and defense, it is not known how many times that of the rammed earth wall!

Even if the Tubo army cracked a layer of the concrete outer wall today, it would not reach the depth at all. How much concrete did they break through with great effort?Is there a thickness of half a meter on the periphery?

Moreover, Li You knew that the reason why the Tubo army was able to crack the cracks today was probably not because of their collision, but because the volume of concrete poured by Li You was too large, which resulted in the release of hydration heat. temperature cracks.

This is an unavoidable situation for concrete with super large volume and area.

Although it will jeopardize the long-term use in the future, it has no effect on the current hardness, and most importantly, this move can provide an unparalleled strong defense!

In general, the advantages of Li You's extensive watering far outweigh the disadvantages, and within a certain period of time, Songzhou can truly be transformed into an absolutely invincible steel fortress!

As for the durability issue, it will not be too late to readjust after the Tubo army retreats.

It was just these reasons that Li You was not very good at explaining to the generals who didn't know anything about it, so he thought about it and suddenly showed a kind smile that made everyone present feel a chill behind him.

"." In order to prevent Songtsen Gampo from being too arrogant, I will let him and the group of Tibetan barbarians see it tomorrow. What is real despair!"

Chapter 796 Collapsed Songtsan Gampo and Ludongzan!

Early morning of the second day.

Songtsan Gampo and Lu Dongzan woke up refreshed early in the morning. They planned to command the army to work early today, just to blow up the city walls and gates of Songzhou as soon as possible.

In this way, Tubo can not only win a big victory, but also be able to return to the domestic chaos in time.

However, when the two came to the front of the battle, they thought for a while that they hadn't woken up.

"Um???"

Songtsan Gambo rubbed his eyes, as if in a dream.
