"Did you hear any unusual noises in the city?" Cai Zhong is not only cowardly, but also suspicious of everything!

But this time his suspicion was half right, he suspected that someone was digging tunnels under the city......

A city like theirs, after all, is a private castle, and they can't even build a moat, and they can't be too eye-catching......

Therefore, it makes sense to suspect that digging tunnels under the city, digging dozens of zhang, calculating the direction, and maybe sneaking into the city......

"Ah Lang, don't bother! The old man has his own tricks! ”

The confessor of the Cai family was a chubby old man with a rat whisker, shaking his head and saying, "As long as they dare to dig tunnels, the old man guarantees that they will have no return......

Cai Zhong always felt uneasy in his heart, but when he heard the confessor say this, he was a little relieved!

"Take out all the oil, collect the feces and urine in the toilets, and get ready, and if they attack the city, they will splash it......"

So the old man with the rat beard took people down, buckled a bamboo tube on the flat ground, put one end on his ears, and began to listen to the movement!

"Report to Alang, they are really digging a hole in the ground......"

"Okay, do according to your plan, and allocate you 500 troops......"

The old man took the order and left!

Once the three-foot-thick triad soil is excavated, the ordinary rammed earth inside is much easier to dig because the south is sandy soil, which is relatively loose......

Liu Gou's remnants sped up the progress......

Soon they drilled a hole in the wall that was five feet deep......

Then the flag is blown. The people who broke the group prepared, they went back with wooden shelves and umbrellas, and the people of the blasting team each carried dozens of catties of particles of black fire. medicine

The mountain is now configured with this thing, it is much more mature, and the purification of various ingredients is good, according to the golden ratio, after the configuration is made, it is made into granules with egg whites, which is conducive to moisture-proof and stability!

And as the rebel army sent to various places gradually became a climate, Liu Bei's armed caravan also made efforts, and the raw materials greatly increased, and the output increased day by day!

I got a lot of prisoners and death row inmates in prison, working in three shifts, day and night!

So, now it's working enough and it's working!

Burst. The people who broke the group carefully guarded the medicine on their bodies, because the things thrown down from the city were sometimes a ball of fire, and if one of the medicines was ignited, the group would be scrapped, and the combat intent would be exposed......

So explode. Escorted by other soldiers, the broken group cautiously approached the walls again......

When they finally arrived at the hole, they quickly filled the hole with their own medicine, sealed it, pulled out a thick fuse rope, lit it, and left it calmly......

Of course, this time the people in the city did not attack very hard, mainly because Cai Zhong ordered that as long as they dig a hole, let them dig it, and those who come in from the hole will be cleaned up by their own confessors, the more the merrier......

That's why the attack on the city has weakened! This also greatly reduces those bursts. Fire on the broken hand. The danger of the medicine being ignited!

Burst. Breaking the group, this group of guys is now playing medicine very well, and the calculation is very accurate, and when they just returned to their own camp, they heard a loud and dull explosion, and the ground under their feet trembled a little!

Cai Zhong in the city and his subordinate generals were unstable and almost stumbled......

But this kind of explosion is not enough to blow up the entire city wall!

It's just a big hole that is a few feet square!

That's what Zhuge Liang wants!

"Eight bull crossbow explosions, broken barrels, heavy fire. Arrow Burst. Barrel break, ready, target twelve o'clock direction, hole in the wall, launch! ”

Then there was a roar and a sharp sound of breaking through the sky, followed by a loud roar!

The big hole soon widened, and finally a huge gap was blown open in the city wall!

In fact, Zhuge Liang can completely explode with a heavy rocket. Bombarding the city gates!

However, the city gate is a heavy wooden gate wrapped in iron or copper skin, and after it is exploded, it is bound to attack through the city gate, and encounter the ambush of the urn city, no matter what, it will be a loss of soldiers!

Zhuge Liang's shock factor this time was greater than the siege factor, so he chose to use this kind of sound and visual shock effect to tear their heavy city walls alive!

When the city wall was about to collapse, Cai Zhong woke up from the shock, his first thought was to run for his life, as long as he could live at this time, even if he was immediately turned into a dog, he was willing!

So he took a few henchmen and fled to the west gate!

Of course, when Zhuge Liang was designing to tear apart their city wall, he had already sent three teams of men and horses to ambush at the three gates of the north, south and west, waiting for the rabbit to capture Cai Zhong alive......

Estimating that Cai Zhong had run away, Zhuge Liang ordered people to shout: "Cai Zhong is dead, and the people in the city will not be killed!" Drop your weapons, put your head in your hands, and get out! ”

Everyone in the city was actually stunned, they had no intention of fighting again, because they had already been scared stupid, the buzzing in their ears had just receded a little now, and they could faintly hear the sound, and they didn't know if they would be deaf in the future......

They were awakened by the shouts outside, and they found that they had long since disappeared......
