Tongguan is facing mountains, backed by Weiluo, and close to the Yellow River. If you look down from a high place, it is like an artificial jewel between a steep mountain and a large river.

As a result, its unique regional location has been a must-fight for military strategists since ancient times.

In the early years, when Tongguan was just established and there were not so many cultural relics, the narrow way was even allowed to pass by only one person.

It is one of the most famous and powerful fortresses in China.

When we arrived in the state, although Tongguan's political status and regional location were delegated a lot for various reasons, the remaining strong still made Tongguan seem unbreakable.

After Liu Fangliang was appointed as the commander of the refugee army in Tongguan, he vigorously repaired many fortifications, gradually forming groups of fortifications on the Eastern Front, becoming increasingly large.

Moreover, Liu Fangliang had extremely rich experience. He had all transferred the original military garrisons in Tongguan to the rear by him, and the entertainment venues were also cleaned. At this time, Tongguan was completely a pure fortress.

Zhou Laosi’s house is not far from the Xionghun wall.

When he entered Hai, he saw that there seemed to be no stranger around him. He carefully climbed up the beam of the house, lifted a few tiles, and came out of the roof to check the surrounding state.

The night wind blows by.

The huge Tongguan City was filled with quietness, with only the figures of soldiers passing by hurriedly against the blazing bonfires on the wall and the howlings of beasts from the surrounding mountains and forests made him realize that there were more than 20,000 elite soldiers in this fortress at this time.

"Fourth Master, this battle is probably not easy to deal with. The thieves have very strict defenses. From this house to our mule and horse team, there are at least half a mile away. Moreover, the city is under strict defense, with three lines of defense. Even if we contact the mule and horse team, we may not be able to get through..."

At this time, a thin man, carefully reported to Zhou Laosi below.

Zhou Laosi had his shoulders exposed outside the roof, and his brows frowned tightly when he heard this.

In the past, he really looked down on the refugee army and always believed that the refugee army was a gang of unused and incompetent mobs.

However, at this time, he was truly in the Tongguan Fortress under the control of the refugee army, and then he realized that it was by no means accidental that the refugee army could reach this day.

If it were the official army, even if their Datong army controlled the fortress, how could it be that there would be no woman left in the city?

Can't these fucking days fade out of birds?

However, the refugee army did it!

Moreover, the defenses everywhere are almost meticulous!

Judging from their current status, they have almost no chance...

"Damn it, this Liu Fangliang is really a character!"

Zhou Laosi spat in his heart. If he hadn't really had no choice, how could he, a gentleman, do such a job as a wise man?

But this is already like this at this time. No matter how difficult it is, he still has to do things!

If he doesn't do it, not only will he be in trouble, but his wife, children, and uncles will have to be buried with him.

After thinking for a while, Zhou Laosi suddenly had an idea in his mind and whispered to the thin black man below: "Send someone to climb over the wall to the yard a mile away from the west to make a fire! Remember to choose a reliable person, even if there is an accident, you can't expose us!"

The black and thin man is Wang Pu’s slave. From the time he received this task, he understood his destination. At the same time, he also stared at Zhou Laosi.

At this time, when he heard Zhou Laosi’s strategy, his eyes rolled a few times, and then he understood Zhou Laosi’s intention, and nodded quickly and said, “Fourth Master, I will make arrangements immediately.”

Soon, a few black shadows, like raccoon cats, quietly took out the yard.

...

At this time, Liu Fangliang had not yet rested, and had not even taken off his armor. He was wearing a silver armor and a cotton coat, and was drinking wine with peanuts and interested.

Just like the Taiping Heavenly Kingdom later, the upper class of the refugee army implemented a policy of feeding chicken soup to the lower class, but the levels that should be found in the upper class were still very good.

Liu Fangliang is now very economical to drink only a little wine.

“Master,

(This chapter is not finished, please turn the page)

They moved!"

On this side, Liu Fangliang had just picked up a peanut and was about to put it in his mouth when the personal soldier suddenly came over to report, his face full of frost.

"Um?"

Liu Fangliang's brows instantly sternly, "Where have you gone?"

"It should be in the direction of the official department, and Beizi has already set up a net of heaven and earth outside."

The personal soldiers showed a smile with excitement, but the smile was full of cruelty!

Liu Fangliang nodded slowly and tasted a sip of wine: "Don't worry, wait until they do it, you can do it!"

"yes!"

Seeing the personal soldiers leaving, Liu Fangliang narrowed his eyes hard: "I love you as a talent. I wanted to leave you a way out, but why are you just uninterested? Is it really that difficult to do some business with our Dashunchao?!"

...

"It's gone, it's gone!"

"Put the fire, put out the fire!"

As the end of the Hai Dynasty approached, a fire suddenly ignited in a house not far from the official hall of Tongguan City, mixed with crackling sounds.

This soon caused chaos in the city, and countless figures rushed out and began to put out the fire.

The wisdom of the working people is infinite.

The fire prevention facilities of ancient people were already very scientific, and they were all lessons learned from countless blood and tears, especially fortresses like Tongguan City, which are even more so in this regard.

In addition, the surrounding houses are all vagrant officers, which are very efficient.

Even though the fire position chosen by Zhou Laosi and the others was very tricky and could burn elsewhere with a little wind and spread, they were still quickly controlled by a bucket of well water and only burned to three houses.

Amid the fiery fire, Liu Fangliang's personal soldier watched from a distance with cold eyes, without any fear, but instead laughed more and more cruelly.

He had already begun to think about what method he should use to peel off Zhou Laosi's scalp and make his spoils.

"Boom!"

"Boom..."

However, just as a group of honest refugee soldiers were about to go to the house to put out the fire and completely wipe out the fire, a big explosion suddenly occurred in the house, and dozens of unlucky people were directly overturned.

The personal soldier also looked terrified and rushed forward quickly, "What's going on?"

"Master, I don't know. There seems to be something inside, so I must control it as soon as possible!"

"Uh, fuck him, the dog is so silly! Go and put out the fire quickly!"

The personal soldiers had no time to take care of anything else. If the fire was not controlled, it would easily ignite into the official hall. Then, if Liu Fangliang was disturbed at that time, he would not be able to bear this responsibility.

Just as the fire was in full swing here, Zhou Laosi gritted his teeth and summoned his side to follow him, "Run over and blow up the city!"

"yes!"

The dozens of people were no longer able to rely on tricks. They just rushed around while throwing torches, mixed with some small turbulent bombs, and rushed straight to the mule and horse camp.

The Mule and Horse Camp had been preparing for a long time, and soon the same rhythm was the same. The people on both sides shone together, and suddenly it caused great chaos in the Guancheng side, and strongly gathered together.

"Brothers, rush! After blowing up the city, we will all be rewarded and promoted to the third level!"

Although the situation was a crisis, the blood in Zhou Laosi's heart was also ignited against the backdrop of countless burning flames around him, and the adrenaline soared infinitely, and he shouted loudly.

"Go! Make achievements in this day!"

"Boom--"

"Boom--"

For a moment, the violent sound of the bamboo-type hand grenade bomb bursting resounded continuously, arousing countless gravels and gravels, and more flames rose up.

Even though the refugee army was prepared for a long time, many people died on the spot before they could react to what had happened.

In just a few minutes, Zhou Laosi and others rushed to the wall.

"It exploded, I'll blow up all the dogs!"

Zhou Laosi had no idea how to be afraid of

(This chapter is not finished, please turn the page)

Nothing happened, and there was a fierce light in his eyes, and he laughed like a ghost.

None of the soldiers around dared to neglect them, and quickly piled up the explosive packs they carried around and quickly led out the leads.

"boom!"

"Boom..."

Not long after, the terrifying burst sounded again between the world, and it was about to tear the quiet night into pieces. Even the many wild animals on the Qinling Mountains felt the vibration and ran away in panic.

However, the solidity of the Tongguan city wall far exceeded the imagination of Zhou Laosi and others.

This kind of explosive pack of equal size only blew up a small half of the Tongguan city walls, and the city gates did not explode.

There is also a urn city outside the city gate and an exterior wall outside the city wall, but there is not much explosive pack.

"Catch them!"

"Dog Damn, I'm going to take their hearts and drink!"

"Kill these gangsters!"
