The reason why Yan Lan wanted to sacrifice two soul seals was because the Demon Sea Demon Monk had two souls in his body.

A soul mark was integrated into the soul of the Lord of Xiaoming Prefecture, and a natural imprint was imprinted on the soul of the Demon Sea Demon Monk.

In just the blink of an eye, Yan Lan had two more royal slaves.

Yan Lan landed on the ground, looking at the Demon Sea Demon Monk with both eyes.

After a while, the corners of Yan Lan's mouth lifted lightly: "Interesting, really interesting, I didn't expect you two to be the targets of the Blood Poison Sect test." What I didn't expect was that the souls of the Lord of Xiaoming Prefecture and the Demon Sea Demon Monk could be superimposed. Although it was not perfect and had major flaws, the power that burst out surprised even me. ”

Yan Lan still remembered the power of the Demon Buddha Demon Seal just now, he thought that the power of the Hand of Death was enough to deal with it, but he didn't expect it to become a stalemate.

Yan Lan continued: "Yes, if I refine you again, the power you fuse together will surpass the powerhouses of the ordinary Nine Yan Distraction Period, and even become my fifth and strongest imperial slave. ”

Yan Lan put away the Demon Sea Demon Monk and the Lord of Xiao Ming Prefecture, flashed, and immediately came to the entrance of the Blood Poison Gate tunnel, and immediately went down.

After a stick of incense, Yan Lan came to the square before.

After Yan Lan appeared, the punishment came instantly.

Youxing looked at Yan Lan thoughtfully, and said, "Have you rested?"

Yan Lan smiled: "Almost." ”

You Xing said: "Then let's carry out our cooperation." ”

Yan Lan said: "Please lead the way." ”

You Xing stretched out his hand, and the light shimmered, and the ground slowly opened a passage.

Yan Lan remembered that on the way here before, he encountered three forked holes, so he said: "I didn't expect that there are many passages in the Blood Poison Gate, I am very interested in where the other two caves I encountered on the way before lead, I don't know if the elder of the big pavilion can satisfy my curiosity." ”

"It doesn't hurt to tell you, the middle one leads to the place where the master of the gate is, and the other leads to the place of testing." This gate is in the Ten Thousand Poison Mountain Range, and there are thousands of tunnels, and they are connected to each other, and there are countless of them. ”

Yan Lan nodded and said, "No wonder the Imperial Kingdom has sent people to kill you, but they have not been able to do so, it seems that the location is very important." There are three holes in the cunning rabbit, and you are afraid that there are more than ten thousand holes. ”

You Xing smiled faintly, didn't say anything, and walked down the tunnel.

Yan Lan followed, and at the same time tightened her mind. Here he cannot trust anyone and needs to be on the highest alert at all times.

The tunnel was extremely deep, and even if Youxing and Yan Lan almost floated down the steps, it would take them three sticks of incense to reach the dark space underground.

Yan Lan swept around, and noticed that there were prohibitions everywhere here, connected by rings, and the whole body was moved, and if he wanted to break it, he could only break it, and he couldn't break it at all.

In the dark space, there is actually a building hall.

The hall is 100 zhang high, thousands of zhang square, although it is slightly inferior to the large buildings on the ground, but it is placed in this extremely deep underground, it is enough to be called a behemoth.

You Xing said: "Come in with this pavilion, remember, you must not stay away from this pavilion, otherwise you may encounter danger." ”

Yan Lan nodded, and quickly followed Youxing. It's not that he's afraid, it's that more is better than less, and he still knows very little about the roots of the Blood Poison Gate.

You Xing pushed open the door of the hall, and suddenly the wind gusted, making people's bones cold.

Yan Lan didn't feel much about the cold changes, but the countless roars and moans that suddenly came from inside the door felt an inexplicable trembling in his heart.

There is anger to the extreme, there is deep grief, there is bitterness, there is pain and murmuring...... It contains almost all the negative emotions of human beings.

Yan Lan suddenly took a deep breath, which reminded him of the inhumane blood pool spirit extraction method that Xuanzong had once carried out in the Frost Country, which was simply purgatory on earth, and it was miserable.

However, Yan Lan's current insight and mind are no longer the same as they were at the beginning, so his expression is still cold.

Yan Lan stepped into the door of the building.

At the moment of entry, an endless array of complex instruments and devices come into view.

With Yan Lan's knowledge, there is no way to know why these facilities are used.

Some are like formations, some are like magic weapons, and some are like some kind of exercises...... Dazzling, hard to tell.

However, in these facilities, there are souls in them, and from time to time there is a terrible howl of broken souls.

If Yan Lan didn't know it in his heart, he really thought that he had come to the legendary hell.

Yan Lan couldn't help but said: "Your blood poison sect is really poisonous, if the imperial kingdom knows that you are carrying out these inhumane experiments, it will definitely wipe you out completely." ”

You Xing sneered: "Those who have achieved great things, how can they be restrained? What's more, most of the original owners of these souls are not good people. We either need the souls of people with extreme talents, or the souls of the most vicious, and the rest of the souls are useless to us, so naturally we don't bother to get them. ”

"However, how can the soul of a talented person be so easy to obtain, otherwise we would not have held the soul of Yanyun Painting Mother hostage for so many years, in order to get the soul of Yanyun Painting. So more than nine out of nine here, all of them are the souls of the most vicious people, and you don't need to be pitiful. ”

Yan Lan frowned slightly, for this, he didn't choose to doubt, nor did he choose to believe it all, the Blood Poison Sect must have initially used the souls of many ordinary people to conduct a lot of experiments, and finally found that the souls of Tianjiao and the most ferocious and evil people were more suitable.

Yan Lan followed the pace of punishment and walked forward slowly.

After turning around, Youxing stopped.

Yan Lan also came to Youxing's side and leaned over.

At the foot of Yanlan, there is a circular cave with a diameter of 100 zhang.

Inside the cave, the energy of countless colors is surging like boiling water, making it impossible to see what exists in the depths of the cave.

Red, green, violet, yellow...... Randomly transformed, reflecting Yan Lan's face.

Yan Lan took a deep breath and said, "What is this?"

You Xing stared at the cave and said: "This is our ultimate test, the fusion of human soul and beast soul, once successful, it is bound to shock the world." ”

A frenzy erupted in his pupils.

Yan Lan was shocked and said, "You guys are crazy. ”

You Xing grinned his teeth and said, "If you don't go crazy, you won't survive." Our Blood Poison Gate doesn't want to be permanently hidden in the Ten Thousand Poison Mountain Range, but how difficult it is to break through the Anti-Heaven Nirvana Realm, without the strong people of the Anti-Heaven Nirvana Realm, our Blood Poison Gate will never be able to see the light of day again. ”

You Xing suddenly turned his eyes to Yan Lan and said, "You may think that our Blood Poison Sect is clinging to the Ten Thousand Poison Mountain Range, relying on the terrain to protect it. But for us, this is not a kind of imprisonment and blockade. No matter how big the Ten Thousand Poison Mountain Range is, it is no bigger than the outside world after all. We need to counter the power of the Empire's pinnacle powerhouse, so we have no choice but to do so. If you want to survive, sometimes you have to do whatever it takes. ”
