It was late at night, and at the third watch, the cold wind was raging. The snow fell in torrential waves, and it became heavier.

At night, Chang'an completely calmed down from the hustle and bustle of the day, except for a limited number of places such as Pingkangfang, which were still bright and green, singing and dancing, the rest of the places were dark. Silent and solemn, like a sleeping ancient beast.

The huge gates of the city have long been tightly closed. There was silence all around, only the howling of the cold wind could be heard, and occasionally a string of lights flashed on the city walls, which were patrolled by the guards of the city.

As the imperial capital of the country, Chang'an naturally has the strongest and tallest city walls.

Li Mingyu looked at the three zhang high city wall in front of him, all of which were made of stones, towering like a giant dragon, and was a little worried.

Although he had ropes with him, relying on such rudimentary tools, whether he could climb the tall and steep city wall covered with snow and ice, it was no small challenge for him to rely on the soldiers who patrolled back and forth on the city wall.

Moreover, for the sake of safety at night in Chang'an City, a curfew system has always been implemented. One hundred and eight square markets, the square that divides Chang'an, horizontal and vertical, neat as a chessboard. During the day, the traffic is busy, the flow of people is like a tide, and at night, the shop must be closed. There is also a special Wuhou Xun who is more valuable at night, once he catches the night and walks around at will without anything, it must be fifty boards, and he will never be spared.

Curfews have existed since ancient times, and their origins can be traced back to the Zhou Dynasty. "Zhou Li: Autumn Lawsuit Si Kou" lists the position of "Si Kou Shi" and clarifies its functions: "When you are in charge of the night, you divide the night with the stars, and you can ban the night with the edict of the night warrior, and you will be a morning walker, a night walker, and a night traveler." This is the earliest record of a curfew. During the Qin and Han dynasties, curfews were strictly managed, and high-ranking officials and princes were also required to abide by this law. In the Tang Dynasty, although it was more liberal and open than the Qin and Han dynasties, it had a more severe curfew system than before.

Since Li Mingyu left the secret stronghold of the Evil Tiger Gang, he took the application with him and set off overnight, wanting to infiltrate Chang'an and find the lair of the Evil Tiger Gang to take revenge.

There was nothing to use in the land temple, and when he searched around, he only found a bundle of ropes, a few sets of old clothes, and two horizontal knives that he carried. This is all Li Mingyu's equipment at the moment.

He originally planned very well, when he was a special forces soldier in the army in his previous life, he received all kinds of professional training, especially good at special operations skills such as infiltration, sneak attack, ambush, assassination, etc.

During the exercise, even the enemy's base camp was heavily guarded, all kinds of traps were densely packed, and high-tech reconnaissance and counter-reconnaissance methods were endlessly emerging, but it couldn't deal with you, an ancient city more than 1,400 years ago?

A modern building that is several storeys high, smooth as a mirror, and has no trace of strength to draw on, can be climbed up with just a rope, and what is the ancient city wall?

However, after Li Mingyu observed it with his own eyes, he was a little dumbfounded, this wall is not afraid of being high or steep. But there's still a lot of snow and ice on it, and it's slippery and wet to the touch, so what should I do?

Retreating in the face of difficulties is not Li Mingyu's habit. He hid in the shadows, his eyes fixed on the soldiers on the ramparts, looking for blind spots in their route and suitable places to climb.

Not long after the founding of the Tang Dynasty, military discipline was quite strict. Although the weather was freezing and the snow was falling, the teams of soldiers defending the city still dutifully patrolled back and forth in their respective defensive areas, almost guarding the huge city walls tightly and impermeable.

The hard work paid off, and after observing for nearly half an hour, he finally found a loophole for Li Mingyu.

There was a section of the city wall that was supposed to belong to the junction of the two defense areas, and every quarter of an hour, the two teams of soldiers would meet again, and then say hello before turning around and continuing to patrol their defense areas.

There is less than a quarter of an hour left for the next meeting of the defenders, and you must race against time to get ready!

Mingyu seized the time to first hit a few military body punches, moved his frozen limbs that were almost blown by the cold wind, and adjusted his body to the best state.

Then, tie the two horizontal knives cross-tied behind his back, raise his hands and legs, and there is no hindrance.

The old clothes found in the Land Temple were torn into strips of cloth two inches wide and more than a foot long.

Then the strips of cloth were stirred into a strand of rope, which began to be wound around the boots and knotted at the soles of the boots, firmly forming a dead knot at every inch. After a while, a pair of feet were wrapped around a dozen strips of cloth.

"Well, it feels okay!" Li Mingyu jumped on the spot, took two steps back and forth, felt that it did not affect walking, and nodded with satisfaction.

He did so, too, out of necessity, as the walls were covered with stubble and snow, wet and slippery, so he had to tie knotted strips of cloth to the soles of his boots in anticipation of increasing the friction between the boots and the walls. As for how much it will be used, only God knows.

Then wrap his hands with strips of cloth, Li Mingyu wrapped them very carefully, not too thick to affect the sensitivity of his fingers, so as not to be unable to grasp the rope. It can't be too thin and won't work, it will not only slip, but also easily wear out the palm.

Finally, I found a branch of suitable length and thickness nearby, tied the rope firmly on the branch, and made a simple version of the flying hook.

After finishing all this, calculating that the time was almost up, Li Mingyu bowed his head and came to the bottom of the city wall.

While listening to the "creaking" footsteps of the leather boots of the city patrol soldiers on the wall, he silently counted the time in his heart.

The footsteps moved from far to near, and then slowly faded away.

Li Mingyu took a deep breath, the opportunity has come!

He took out the rope and threw it upwards with a soft force against the city. Watching the branches tied with ropes fly towards the head of the rope, Li Mingyu's heart also rose to his throat, and success or failure was here.

The situation on the wall is unknown, and he prays that the branches of the trees will not fall to the ground without making too much noise, which will arouse the alarm of the city patrol soldiers, and thus lead to all the failures.

The branch with the rope fell to the top of the city, and because Mingyu made a skillful force, it only made a slight sound.

It's done! No one noticed. Mingyu was excited and gently tugged down on the rope. Unfortunately, the slotted branch did not get stuck on the battlements of the wall, and fell back with the force of his tugging.

Mingyu was not discouraged, after all, his hook lock was too simple, and it really took a bit of luck to expect that a branch with a rope tied in the middle of the line could just get stuck between the battlements of the city wall.

Mingyu hurried to continue to repeat the action of throwing up, and muttered in his heart, when he turned back, he had time, he must find a blacksmith to create a set of flying grappling hook locks, be prepared, I can't say when I will use it.

I threw it a few times in a row, and it was finally done!

Mingyu also breathed a sigh of relief. After calculating the time, there is still more than half a quarter of an hour before the next arrival of the city patrol soldiers, which is enough.

Mingyu leaned forward slightly, placed the rope between his legs, pulled the rope alternately with both hands, and climbed up with his arms. At the same time, one foot is firmly against the wall, and the other foot is pushed up.

The three-zhang high city wall is converted into a modern unit of measurement of around 10 meters. It seems unattainable, but it is actually only three stories high.

For a well-trained modern soldier, it takes only the right tools to get up, and it doesn't take a minute to get up.

There are even some thieves who fly on the cornices and walk on the wall, and after continuous hard training, they can climb to the height of 20 floors with their bare hands along the corners of the walls or the cracks of the building in just five minutes.

Fortunately, I don't know if the strips of cloth wrapped around my feet really played a role in rubbing and preventing slips, or if the snow and ice on the wall were not as slippery as I imagined. With little effort, Li Mingyu has already climbed the city wall.

When I went up to the city wall, I looked left and right, and saw that the torches in the hands of the soldiers of the city patrol were still not far from here. Li Mingyu put away the rope and turned to the side facing the city.

It was much easier to go down than to go up, and the only thing to worry about was that after going down, the ropes left on the city wall would be easy to be discovered by the city patrol soldiers.

For this, Li Mingyu was also prepared, chose a relatively hidden battlement on the city wall, tied the rope, tied a knot of kamikaze, and cut off the weak section in the middle.

After this goes on, you can retract a large section of the rope by shaking the rope, leaving only a small part on it. It's not 100% hidden, but it's better than so many big pieces of rope still there.

Li Mingyu concocted the same method, and successfully climbed down the city wall and entered the Qunxian Fang.

Qunxian Fang, close to the west city gate, because the west side is the city wall, all only three sides have the fang wall. The land is close to the west market, the flow of people is thriving, and most of the shops in the square are gambling houses, restaurants, pawnshops, brothels and other shops.

After the Wuhou of Yongzhou Mansion and the guards of Qin Wangfu searched door to door during the day, it was a good toss, and there was no business in gambling houses and other places.

At this time, the shops in the square gate have closed their doors early, and the streets in the square are silent, and it is dark all around. There are only some shops, gambling houses, etc., with half-lit lanterns at the door, which are blown by the cold wind.

Not long after walking along the deserted street, the signboard of the Hongyun gambling stall was already in sight, Li Mingyu pressed the horizontal knife behind his back, and sneered, "Duan Hu, the master is here to ask for your life!" ”
