After a night's rest, Liu Xianyu and his party began to quietly observe the movements of Qingquan Pavilion the next morning, they opened a large room in the hotel opposite Qingquan Pavilion, and the four of them were divided into two groups, one group observed Qingquan Pavilion in the room, and the other group secretly observed the back door of Qingquan Pavilion outside.

In the afternoon, Liu Xianyu and Tang Cheng were in charge of observing outside, and the two of them were lying on a roof not far away, quietly watching the movement of the back door.

【Chew~Chew】

Tangerine kept chewing the jerky in her mouth while staring at the movement at the door, Liu Xianyu looked at her eating jerky seriously, and couldn't help but ask for one, so the two of them lay on the roof together and chewed air-dried meat as hard as wood.

[Tangerine, what kind of jerky is this? It can be dried like this. 】

[This is the meow of the Lord of the Lake.] 】

[Poof! 】

Liu Xianyu spit out the jerky in his mouth at once.

[You said this jerky belongs to that monster?] You dare to eat that kind of thing? 】

[It's okay, you can eat it.] Making trophies into jerky is the traditional meow of the cat demon clan. 】

Tangerine turned his head and stretched out his little thumb to Liu Xianyu.

The two of them stayed here until the evening, and finally saw a few hooded men sneaking out of the back door, and Liu Xianyu immediately knew that this group of people was the target of his waiting.

[Even if you wear a hood, that barrel-like figure exposes you! ] 】

Liu Xianyu looked at the only fat ball-like person in the group, and he didn't have to guess that it must be the owner of Qingquan Pavilion who received the box that day.

【Tachibana, let's go!】 】

Liu Xianyu first took out the Rubik's Cube and sent a message to the two of them, and then quietly followed behind the group of people with Tangerine.

The two of them followed behind the group, and because they didn't dare to get too close, they lost track of the group after a series of turns

[It's not good, I lost it. 】

Liu Xianyu said with some disappointment, but he didn't expect the orange next to him to hold his hand.

[Meow this way.] 】

Liu Xianyu was dragged by Tangerine to a small alley, and then Tangerine flexibly climbed the wall of the alley, only showing his head and looking around.

[Found it!] 】

Tangerine jumped off the wall and led Liu Xianyu to a dilapidated garbage dump.

"They came in. 】

Liu Xianyu looked at Tangerine in surprise, as if he didn't understand how Tangerine knew the whereabouts of those people.

【Tachibana, how did you know they were here?】 】

[Tangerine is a cat demon meow! ] Stalking prey is an instinctive meow. 】

Tachibana reached out and touched the two cat ears on top of her head.

Liu Xianyu thought to himself that the demon race was a race full of cute girls with beast ears, but he didn't expect such a powerful setting.

He pulled out the long sword on his waist and cautiously walked into the garbage dump, the pungent smell in the garbage dump rushed to his face, and Liu Xianyu couldn't help but put his hand in front of his nose.

[Partner, the compass has a reflection! ] 】

At this time, the voice of the system came from Liu Xianyu's mind again.

[Whisper, you jumped off me!] 】

Under the already tense situation, the voice of the system suddenly appeared, which frightened Liu Xianyu and almost turned around with a sword.

[Cut, I'm kind enough to remind you, who knew that you were so timid, so you can't keep the system interface open? You have to remind you of something every time, and if I don't find out, are you missing out? 】

[Anytime, anywhere, the field of vision will be covered by a bunch of inexplicable interfaces, which will greatly affect my life, okay! ] 】

Liu Xianyu opened the system interface as he spoke, turned left and right in the garbage dump according to the instructions of the compass, and finally stopped in front of a dilapidated staircase that went down.

[Shall we wait here for the Jade and them to come over and then go down?] 】

Don't look at the usual Liu Xianyu's attention to jade, he looks disgusted, in fact, he always feels at ease if he doesn't bring a nurse before the next copy.

[It's okay, Tangerine left a code for Thelyss along the way that only the two of us can understand! The two of them will be here soon. 】

Sure enough, within a few minutes, Ikatris and Emerald arrived.

Seeing that Ikatris and Jade didn't seem to be affected by the smell in the garbage dump, he knew that Jade must have used magic to isolate the smell in the garbage dump, Liu Xianyu hurried over:

[Hurry up and give me an air purifier too.] 】

Jade stretched out her hand and performed an atmospheric purification on Liu Xianyu and Tangerine, and then the four of them looked at the stairs in front of them.

[I'll go ahead with Hyunwoo.] 】

Ikatris still bravely took on the role of striker.

[No, this time it's better for me and Tachibana to go ahead, your shield of light is too bright and easy to expose, on the contrary, Tachibana and I don't need too many light sources to see the road.] 】

Liu Xianyu, as a Golden Pupil Spirit Clan, is still far beyond ordinary people in terms of eyesight, although he is not like Tangerine, he can not be affected at all in the dark night, but he can see some of it.

【…… Indeed, then you two be careful. 】

Ikatris said with some depression.

The four of them walked down the dimly lit staircase, the path was normal at first, and less than a hundred meters further on, the surrounding environment gradually changed from artificial buildings to natural tunnels, and the walls around them had turned into rough rocks.

What the hell is this place? Why is there such a long tunnel in the dump? 】

Liu Xianyu guessed with some curiosity.

[It can't be a dungeon or something, right?] 】

Jade's voice seemed to be filled with disgust.

At this time, Liu Xianyu and Tangerine, who were walking in the front, suddenly stopped.

[What's wrong?] 】

Jade couldn't see anything behind, so she could only ask Liu Xianyu and Tangerine.

You can cast a lighting spell. 】

Liu Xianyu's voice came, Jade had long been fed up with this feeling of darkness, and immediately raised her hand to be a light technique, and a soft ball of light rose from her palm and instantly illuminated the surroundings.

She finally saw the scene in front of her, which was a stone cave several square meters in size, and the front of the stone cave was blocked by a strange stone door, and with the help of the bright light, she could clearly see that the stone door was carved with all kinds of strange patterns.

Jade walked over curiously and took a closer look, and found that she could recognize most of these magical beasts.

[What does this Warcraft Illustrated Book mean?] And strangely enough, these monsters seem to be all from above? 】

Listening to Jade's words, Liu Xianyu also came over, he didn't know most of the demonic beasts here, but there were a few rare demonic beasts that he had seen in the books of the spirit clan. According to Jadeite, the magical beasts in the Spirit Clan's books are basically antiques from hundreds of years ago, many of them are extinct, and most of them have undergone a lot of changes in the past few hundred years.

But the appearance of those extinct demonic beasts in this mural made Liu Xianyu a little strange. He immediately told Emerald about his discovery.

[Forget it, it's not surprising that there are extinct monsters in the ruins, let's find out how to open this door.] 】

Jade gave up thinking and began to lie on the wall, looking around for a mechanism to open the door.
