Dirty, messy, sewage flowing, and unpleasant smells filling the sewers, this is Su Yi's first impression of this place. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Creak~

It was the sound of a mouse, gnawing on something I don't know what it was, Su Yi looked at it and broke out in a cold sweat, it was a human arm, it was rotten, and it was crawling with maggots. Here, how can there be rotten arms? Su Yi didn't know, but his intuition told Su Yi that he couldn't stay here for a long time.

"Wolf, where are you going?" Su Yi asked, there are many forks in the sewer on the second floor, but which one is the exit?

"Come with me......" Wolf seemed to know the terrain well, and without even thinking about it, he walked towards the sewer fork on the left.

The space here is not very large, and the three of them can only crouch slightly.

Wolf is just a businessman, Su Yi doesn't know how he is so familiar with the environment in the sewer, speaking of which, Wolf is not only familiar with this place, but also seems to be familiar with the structure of the entire prison, like the entrance to the sewer before them, it is very difficult to find, and it is impossible for ordinary prisoners to find this entrance.

Su Yi couldn't help the curiosity in his heart and asked Wolf.

It turned out that he was a real estate businessman at the beginning, and then found some connections, and the lord of Sunset City granted him the land of the prison, which was not a prison at the beginning, and said that this place was not within the scope of Sunset City, and the original prison was too simple, so the lord planned to rebuild it, so this piece of fat fell on Wolf's head, he was not the chief designer of this prison, but one of the investors, he had come here to investigate, so he was familiar.

As he spoke, the sewer in front of him was touched by Su Yi and others A sentence of corpse bones, the temperature in the sewer is very low, this sentence of corpse bones seems to have been dead for a long time, but there is still a little flesh and blood left on it, and there are a few mice gnawing on it.

"This ......," Fire said with pleasure.

The previous severed arm and the bones here all reminded Su Yi that Sunset City Prison was not as simple as he thought.

"Wolf, do you know what's going on?" Su Yi frowned.

"I know some, but it's not convenient to say here, let's go out and talk about it." Wolf said.

"Okay."

As he spoke, several people sped up again.

Walking through many passages in a zigzag, Su Yi could clearly feel that the terrain of the sewers here seemed to be oblique.

"It's almost there......" Wolf said.

After a few more minutes of walking, a bottomless, downward passage appeared in front of the eyes of the three of them, and there was a foul smell from there, and Su Yi and the others couldn't help but wrinkle their noses.

The passage was tilted down, and there was an iron gate blocking the way, which was obviously locked, Wolf got out of the way, and Su Yi walked over with understanding, and took out the remaining two lock picks.

It is a lock of hard difficulty.

Also, Su Yi is sure to open it.

It only took one to open the lock, and the stench was even stronger.

"Let's go......" Wolf said.

"Wait! Brother, you're not kidding, right, where does it lead down there?! Fire Joy exclaimed. Although this is a game, the bottomless passage in front of him makes him feel terrifying.

"The underground lake, shut down when it touches the water, one thing I want to remind is that no matter what you see, don't make any noise, let alone take the initiative to touch it, otherwise everyone will suffer if something happens." Wolf said solemnly. It doesn't look like a joke.

Fire nodded happily.

Su Yi asked suspiciously.

"Could it be that there are some other monsters down here?" Su Yi said.

"Don't mention it, you'll find out when you go down." A hint of fear appeared on Wolfe's face, fleeting, but who is Su Yi? This reaction was noticed by Su Yi. The latter looked down with some expectation.

"Are you ready?" Wolf asked.

Su Yi and Huozhi nodded happily.

"Three, two, one!"

After counting, the three of them walked into the inclined passage at the same time, the angle of inclination was nearly 90 degrees, and their bodies were not controlled by Su Yi and the others at all, and they went straight down.

The smell of decay in the passage was very unpleasant, and Su Yi frowned.

Brush brush brush ~~

The bodies of the three of them swiped down at great speed, to Su Yi's expectations, they thought that this passage was very long, but in less than half a minute, they only heard a plop, and the bodies of the three of them suddenly entered the underground lake.

The cold chill invaded to the bone, and this was Su Yi's first feeling after entering the water.

The water was not very deep, and the fire was happy to swim upwards without opening his eyes after entering the water, but just swam desperately upwards, and so was Wolf, who swam directly towards it without the slightest hesitation.

In addition to the cold chill to the bone, after entering the water, Su Yi felt like he had fallen into the edge of hell, and his whole body was terrified, but Su Yi knew that this was just a game, and it would not really hurt him, just data, Su Yi was very curious about what was in the water, and he slowly opened his eyes.

The sight in front of him shocked him.

This underground lake does not want to be dark as Su Yi imagined, but the bottom of this underground lake, emitting a faint blue light from bottom to top, with the darkness, it feels very beautiful and beautiful. Su Yi swam down curiously.

The bottom of the water is not very deep, Su Yi only swam for more than ten seconds to the end, and then Su Yi found that at this time, a strange fungus, they resemble jellyfish, they are transparent, and they emit a faint blue light, which is very beautiful.

Looking around, Su Yi's eyes were sharp, and he suddenly found a treasure chest in the dense area of blue mushrooms, and immediately swam over with some excitement, treasure chests are very rare in the game "Killing World", as long as your subclass turns into a thief, and you will not open a special treasure hunting skill until your thief is upgraded to a certain level.

Su Yi wanted to turn to the sub-profession of thief at the beginning, which was still more practical, but he didn't regret it, after all, assassins were not bad, and his Shadow Medal needed to kill people to increase his attributes, and the assassin was undoubtedly very helpful for Su Yi to upgrade the Shadow Medal.

After swimming there, Su Yi hurriedly opened the treasure chest, and now he obviously felt that his lung capacity and physical strength were not enough, and if he continued like this, he would have to deduct blood.

Unlike the last hidden mission, this is a locked treasure chest, and now you only have a lock pick, so you only have one chance.

Luckily, this is a treasure chest on Hard difficulty.

Entering the unlocking screen, Su Yi calmed down, much more serious than before, after all, there is only one chance.

Half a minute, there is no danger.

Bite!

[System: You have successfully opened the treasure chest and obtained the item: Hundred Ghosts Night Walk.] 】

"Hyakki Night Walk? What the hell is this? Su Yi didn't think much about it, picked up the things and swam up there......
