Wu Yan gently opened the golden lid of the small stove, only to see that in the small stove, there was a thumb-sized blue ball of light rolling. The "Netherworld Xuanyue" that had just floated on the high platform seemed to have shrunk more than ten times at this moment, quietly floating in the blue ball of light, and the blue ball of light was like a glass ball, rolling in the small furnace.

What's even more strange is that on the inner wall of the small furnace, which was originally as smooth as a mirror, there is actually an additional dark blue mark pattern that is exactly the same as the "Netherworld Xuanyue". The pattern is like a watermark on its inner wall, and it is extremely smart. Wu Yan reached out to touch it, except for a slight hint of coolness, there was nothing unusual. It was as if the pattern was part of the little stove, and it was very strange and strange.

Wu Yan stretched out his hand and grabbed the ball of blue light from the small furnace, and suddenly, his face changed suddenly. That ball of blue light, as soon as it left the small furnace, it was so heavy that Wu Yan didn't pay attention and almost let the ball of light roll out of his hand. Fortunately, Wu Yan's eyes were quick, so he put his arm down and then retracted it upward, so that he could firmly grasp the ball of light.

Obviously, this seemingly inconspicuous small ball of light was actually a special spatial forbidden array that sealed this "Netherworld Xuanyue". Come to think of it, this "Netherworld Moon" will never be so big. Wu Yan hurriedly took out a jade box from the storage bag, put the ball of light into it, and then pasted several special forbidden talismans, and then carefully put the jade box into the storage bag.

Seeing that several parties are looking for this "Netherworld Xuanyue", I don't know how many people know the origin of this thing. However, the only one who really knows is the Mi Tu Tu, otherwise, such a secret treasure that even an old monster like Mi Tu who has lived for thousands of years has to snatch at any price, how could the Demon Mansion and the Immortal Sword Sect only send a few monks from the Jindan period to look for it?

These people must know that this thing is extraordinary, but I am afraid they may not know the origin of this thing. Although Wu Yan really wanted to keep this thing for himself, but thinking that Senior Brother's life was still in the hands of Zhu Junhao, besides, if this thing really remained in his hands, it might not be a good thing. Thinking about it, Wu Yan had a headache, and it was difficult to make a decision.

At this moment, a loud bang was heard, followed by the shaking of the earth and the shaking of the mountains, and then, a certain layer of illusion magic circle in the entire Qingniu Cave Mansion suddenly disappeared like a torn painting.

An underground cave with a height of about hundreds of zhang and a radius of about ten miles appeared in front of everyone's eyes in an instant.

This underground cave was almost hollowed out of an unknown mountain. In the center is a small island with a radius of several miles and a height of about 100 zhang. Wu Yan was standing on top of the ruins of the palace at the top of this small island at the moment. The island is really like a lonely island in the ocean, and it is really surrounded by blue waters, and the blue waters, which are instigated by some force, actually roll the tide and beat the beach at the foot of the hill around the island.

The dome of this huge cave is inlaid with countless huge moon fluorites, illuminating the entire cave as bright as day.

Zhang Feng and Bi Xueqing had already arrived at the foot of the island at this moment, looking up at Wu Yan.

Hundreds of feet away from this small island is an abrupt cliff that rises from the sky. Dozens of feet below the cliff is the blue water.

In this cave, the scene is really very different. In particular, the blue waters below may seem to be the same as the sea, but a slightly experienced monk can detect a very strange dead aura from the surface of the water.

This is no ordinary seawater, and even more so fresh water.

Such strange waters caused the two groups of monks on the cliff to try and try to fly away and reach the top of the immortal island where Wu Yan was, but no one really dared to do so.

After Wu Yan saw those people, his face immediately sank. The location of those people is obviously the only exit from this cave. Because, except for the cliff, there is a hole that connects to the outside world, and the rest of the place is all blue-brown mountain rocks, and there is no hole or anything like that.

If they wanted to leave here, Wu Yan and the three of them had to return to the cliff where the group of people was.

All the way from the mountain of Immortal Island to the foot of the mountain, after meeting Zhang Feng and Bi Xueqing, Wu Yan asked Zhang Feng in a low voice: "Second brother, look over there, there is nothing abnormal about the monks of your Immortal Sword Sect, right?"

After such a long time, Wu Yan didn't dare to guarantee that after a life-and-death struggle, none of these people had any accidents.

Hearing this, Zhang Feng glanced at Bi Xueqing, and the two of them focused their eyes on the group of monks from the Immortal Sword Sect on the other side at the same time. After a while, Zhang Feng said: "Big brother, the Immortal Sword Sect has lost a lot of people, and this place is too far away from there, and the younger brother can't really see it, so he doesn't dare to make a judgment." ”

Wu Yan nodded, no longer spoke, but kept rubbing his chin with his hand, as if something was difficult to solve, causing him to start pondering.

"Brother Wu, Brother Feng, look, there are corpses in that water!" Bi Xueqing suddenly pointed to the distant waters and shouted to the two of them in shock.

Wu Yan and Zhang Feng looked in the direction of her finger, Wu Yan frowned, and then sighed: "It's your Senior Brother Zhao." ”

"Senior Brother Zhao, is he already dead?" Bi Xueqing shuddered violently, leaned closer to Zhang Feng's side, and asked with a slightly pale face.

"It should be dead, right? Alas, I really should have persuaded him at that time, if I hadn't suddenly shouted that voice and rashly threatened him with what the master didn't allow, I guess there would have been a chance to persuade him back, right?" Zhang Feng looked at the floating corpse in the distance with regret.

"Second brother, sister Qing'er, you don't need to blame yourself. This person is greedy, and he knows the danger, but he resolutely breaks in, and he deserves this catastrophe. This is the Phantom Dead Sea, and it seems that they have only broken the first illusion circle of the Qingniu Cave Mansion, and have not been able to break the second illusion circle. This is trouble!" Wu Yan frowned, comforted the two of them, rubbed his chin again, stared at the blue water in front of him, and pondered.

"Phantom Dead Sea? What a terrible name!Brother Wu, how do you know this is the Phantom Dead Sea?" Bi Xueqing asked in a trembling voice when she heard the name of this water area so terrifying, and leaned closer to Zhang Feng's side.

"Listen to people. By the way, second brother, Sister Qing'er, among the green ox relics you picked up just now, are there any jade books or anything like that?" Wu Yan suddenly thought of something, turned his head and asked the two.

Zhang Feng patted his head and said with a guilty face: "Look at my brain, I was only thinking about how to get out of here, and I forgot to take out the treasure I picked up and share it with my eldest brother." ”

Bi Xueqing looked at Wu Yan with a strange face, and then at Zhang Feng, without speaking, but consciously took out a storage bag and raised her hand to Wu Yan.
