Song Ying'er pondered: "Eight hundred years ago, all countries were tracking Cang Wushuang, and they must have collected a lot of relevant information, and these confidential information should theoretically be in the imperial cities of various countries, so the news that the thirteen princes know is only afraid that it is not under Cang Wushuang, maybe the thirteen princes also have their own thoughts." ”

Fang Ling smiled and said, "If both of them have their own thoughts, then let them fight, let's go and watch the fire from the other side." ”

After speaking, the three of them took a turn in the stone hall, the stone hall was connected to several passages, Fang Ling casually walked into one, and found that there was a stone bed chiseled along the wall inside, which was the dormitory.

He immediately looked closely, hoping to find the relics left by Cang Wushuang so that he could figure out the mystery in this underground palace.

The sleeping house is very simple, you can walk to the end after five or six steps back and forth, the four walls are smooth, the stone bed is also bare, there are no bedding sheets and other items, Fang Ling sat on the stone bed, and suddenly felt a chill rising from the ground, the cold air of the underground is even more piercing than the moon yin and ice, especially now that it is a hundred zhang deep from the ground, it is Fang Ling's cultivation, lying on it at night to sleep on it, I am afraid that it will be cold and shiver.

Cang Wushuang regarded this place as his residence, and opened up such a vast earth palace, his cultivation was definitely above himself, and it was estimated that he had already reached the realm of the peak of martial arts.

Thinking of this, another question rose in Fang Ling's heart, if Cang Wushuang was really a disciple of the Immortal Sect and had such a powerful magic weapon, why would he build an underground palace and bury himself here?

The more Fang Ling thought about it, the more confused he became, only to feel that there was indeed a big mystery in this thief king, and at this moment, he suddenly caught a glimpse of a slight gap in the corner of the stone wall opposite.

Fang Ling hurriedly squatted down, took out the Xie Immortal Dagger and gently pried it against the gap, and a square stone immediately fell down, revealing a small hole inside, and a book of parchment was suddenly placed inside.

Fang Ling was overjoyed, and hurriedly took out the parchment, at this time, Xiao Xue's two daughters walked back from other passages, and they didn't seem to find any leftovers, and when they saw Fang Ling holding something in their hands, the two daughters rushed over.

Open the parchment book, the first page actually recorded the area map of the first floor of the underground palace and the distribution of the living stone labyrinth, from the map, the first floor is divided into six areas, do not interfere with each other, there are three entrances and six exits to the second floor.

The second page contains a map of the Tentacle Swamp on the second floor of the dungeon and the location of the Thousand Whiskered Viper, with a total of five areas and five exits to the lower level.

The more the three of them turned backwards, the more surprised they became, no one thought that there was such a treasure hidden here, if they knew it before they came, they wouldn't have to be so worried about passing through here.

And as Wei An speculated, there are only three areas left on the fourth floor of the underground palace, so the chance of entering the encounter is greatly increased, and there are only two areas left on the fifth floor, and there are only two exits, which are named the Soul Attraction Array by Cang Wushuang, and a rare soul attraction stone is buried in the stratum, which can have an impact on the mind of the entrant, and stop the other party by reproducing the souls of their deceased relatives.
