With the passage of time, the snoring of the two people in the room gradually became louder.

The mouth of the demon tied to the iron chain makes a "click click" sound, just like grinding teeth. It kept shaking slightly, making the chain clatter. At the same time, a pair of small red eyes kept staring at the buffalo and monkey in the room.

"Hong'er, let me hug." In his sleep, the monkey made a slight whisper and began to talk in his sleep.

The demon observed for nearly two hours and suddenly stretched out a touch limb from his shoulder. Although his body was bound by chains, his limbs easily broke away because they were too thin.

After breaking away from the iron chain, a layer of strange things suddenly popped up at the tip of its contact limb, just like a small knife. The edge of the knife still emits a faint cold light, making people feel cold.

The demon's body is still twisting slightly, and the sound is very weak, but it is very obvious in this quiet room. But the buffalo and the monkey didn't hear the sound, and even unconsciously, even their breathing kept up with the rhythm of the sound made by the iron chain.

Seeing that the time finally came, the demon extended his touch limb to the iron chain around his waist and began to cut the iron chain with a part as sharp as a blade. The blade rubbed against the iron chain and made a subtle sound of 'stabbing, stabbing'.

Originally, such a sound was enough to wake the buffalo and monkey, but because the demon had been shaking the chain before, they were as used to it and didn't find it.

There was a touch of excitement in the devil's eyes. He made his movements as gentle as possible, but even so, the iron chain as thick as his arm had been cut off in a quarter of an hour.

Time is still passing bit by bit. You can see from the window that it is completely dark.

The iron chain on the demon was finally completely cut off, and the buffalo and monkey in the room didn't notice it. The demon carefully loosened the iron chain that wrapped it tightly with its touch limb, and then put it on the ground. This is a very troublesome process. Although the action is not complicated, it is difficult to make a sound to disturb them, otherwise he will fall short of success.

It took another half an hour, and the demon finally broke away from the iron chain. The ten meter long iron chain was provoked by the demon with several thin limbs, which looked quite funny.

However, the ten meter long iron chain weighs at least a thousand kilograms. Even if the devil has infinite physical power, he has been very tired to keep this posture all the time. If it turns into a human again at this time, it must be sweating.

The demon carefully put down the chain, but the two people in the room slept more and more sweetly.

Suddenly, an iron chain slipped from its limbs and fell to the ground with a loud crash.

Even the devil himself was startled by the news, and his body suddenly stretched tight. He carefully observed the two people in the room. If there was any change, he planned to grab the window directly.

But they were still asleep as if they hadn't heard, which made the demon's mood a lot easier. Continue to put the chain back on the ground, but this time, the devil's action becomes more careful.

Finally he put down the chain. The demon was relieved and walked towards the door. The door was unlocked, so the demon easily opened the door with his touch.

Outside the door was the hall of the big house, and the people of the demon killing group slept on the ground. They are used to sleeping like this. If they sleep on a soft mattress, they will feel uncomfortable.

I've been very tired recently. Now I finally caught the demon and relaxed everyone's nervous nerves. Under such circumstances, they naturally sleep more stably, snoring one by one.

The demon crawled on the ground, tried not to cause any movement, and carefully went down the stairs. After the corner of the stairs, on the first floor, there is the gate. The gate is closed at this time, but the window next to the gate is open.

Although the body of the demon is two meters long, it is very thin. With the support of many limbs, the demon is also easy to remove the window.

There was a cold north wind outside, but it didn't have any effect on the demon. He made a series of "Clara Lala" voices to express his joy. After a while, he quickly slipped into the grass by the side of the road.

A hundred years ago, there was a great plague in Qingguo, which began at the border and then spread to the interior of Qingguo. The plague was so serious that it reduced the population of Qingguo by almost one fifth.

At first, Qingguo thought it was distributed by the Oriental alliance of neighboring countries, which almost led to a war between Qingguo and the Oriental alliance. But in the end, it was found that the cause of the plague did not come from the outside world, but from Qingguo himself.

The real reason for this is also quite embarrassing. There is a huge pool under the ground of every city in Qingguo, which contains water flowing from the sewers in the city. Originally, the pool was closed. After the water entered, it penetrated into the ground. But in the city where the plague first appeared, the entrance of the pool somehow loosened, and then a little boy fell and drowned in the water.

Before long, the plague broke out.

After knowing the truth of the matter, the emperor of Qingguo was furious and found out the officials who built the sewer and cut off all the people. Later, experts were invited to set up an array and open altars under the ground of each city, build canals and dig roads, and lead the water flowing into the ground into the nearest river of each city. In this way, even if another person dies in it, there will be no plague caused by running too long before.

As one of the cities in Qingguo, Guancheng certainly did not fall behind. On the avenue of Guancheng, there will be a water well almost not far away, and the snow and rain falling from the sky will flow in along the wellhead.

When the demon came to the street, he skillfully found a well mouth, opened the heavy iron cover on it, and then jumped down.

Underground is a winding and complicated canal, which emits the smell of corruption everywhere. However, because the canal is very spacious, there is no peculiar smell.

After the devil entered the well, he walked forward. The canal became more and more spacious. At the end, it was a huge pool.

"Clara Lala." The devil's mouth sent out a series of strange syllables, which seemed to be shouting something. The voice echoed underground, looking very gloomy.
