As soon as Elder Xu Chensheng saw Tang Letian, he wanted to drive Tang Letian away. There were unpredictable risks in this ancient formation. No one could fall into it, but Tang Letian could never fall into it.

But Tang Letian came to this relic of the vagrants in the Poor Demon Star Realm, and naturally he would not return empty-handed.

Tang Letian did not leave obediently, but took out the thin-winged knife and sent it to Elder Xu Chensheng.

Elder Xu Chensheng's eyes lit up slightly. He had witnessed the power of the Thin Winged Sword with his own eyes and had always wanted to make one, but he was not the infant who was responsible for killing, so the Thin Winged Sword was not his turn to assemble.

Now with this thin-winged sword, he may be able to break through the formation and come out of Changsheng Mountain.

Elder Xu Chensheng immediately reached out and grabbed the Thin Wing Knife. He shook it gently in his hand. The light and shadow of the Thin Wing Knife flickered. As if nothing was in his hand, it activated the innate energy to pour into the Thin Wing Knife. The Thin Wing Knife immediately became heavy. At the same time, blood vessels seemed to appear on the blade, and bright red liquid wandered around the blade, making the Thin Wing Knife look beautiful and with endless murderous intent. This is a masterpiece created by only God.

"Elder Xu, don't worry, I came here just to take a look and increase my knowledge. I will never go deeper into it. I wonder how Elder Chang got caught in this formation?"

Xu Chensheng collected the energy of heaven and earth that was poured into the Thin Wing Knife. The Thin Wing Knife returned to its original appearance, looking extremely light, as if it was about to break at once, but it was swung without any fragility.

Elder Xu Chensheng couldn't put it down and gently waved the thin-winged knife in his hand and roughly told the story.

Elder Xu Chensheng and Elder Changshengshan made an appointment to search for the dragon pill in the sea of ​​gaze. The journey went smoothly. Shortly after entering the sea of ​​gaze, they searched for a dragon. The two joined forces to attack the dragon, hoping to capture the dragon and collect the dragon pill.

As a result, the dragon was very slippery and rushed through the sea trench. It summoned many shrimp soldiers and crab generals to disturb the sea. However, even so, he was not able to escape from the joint efforts of the two elders.

But the dragon suddenly crawled into a big hole in the trench. Elder Changsheng Mountain went in alone to chase, leaving Elder Xu Chensheng waiting outside to respond. As a result, as soon as Changsheng Mountain entered the big hole, the big hole was suddenly blocked. Elder Xu Chensheng could not wait for Changsheng Mountain to return.

Just as Elder Xu Chensheng tried several times to break the deep sea hole but had no results.

Chang Wei's expression became even more ugly when he heard this. He had just received the voice transmission from Elder Xu Chensheng, telling his father that he was trapped in the ancient formation, and he didn't know many details because it was the voice transmission.

"Elder Xu, now the Thin Yi sword is in hand, can we break the formation?" Chang Wei did not dare to waste time. God knew what changes would happen in the formation. The sooner Changsheng Mountain would come out, the better, so he asked.

Elder Xu Chensheng was actually more anxious than Chang Wei. Changsheng Mountain was trapped in the ancient formation, and the dragon was also in this formation. I still don’t know if there were any other living creatures in the formation. If it was the dragon’s nest, it would be terrible.

Elder Xu Chensheng nodded: "You can give it a try!"

Xu Chensheng then looked at Tang Letian who was eager to try and said coldly: "You are not allowed to go."

Tang Letian hurriedly said, "I'll go to the gate of the ancient formation to take a look. Elder, I'll retreat before you break the formation."

After Tang Letian said this, Xu Chensheng thought about it and nodded slightly. He has been guarding the entrance of the cave these days, and there is no danger there. If Tang Letian retreated before he broke through the formation, there should be no problem.

The group did not waste time and immediately followed Xu Chensheng into the sea.

As soon as he entered the sea, Tang Letian found that the sea water here was indeed a little different from the sea water elsewhere.

There is a faint demonic aura in the sea water, which means that there is a huge demon clan or treasure of the demon clan that is constantly releasing demonic aura.

Chang Wei and Tang Jiuqu also felt the demonic energy in the sea at the first time.

Elder Xu Chensheng said: "This demonic energy escaped from that great formation. When we came here after the dragon, there was no demonic energy in the sea water. The old thing in Changsheng Mountain drilled into the formation and activated the formation. Then the sea water here was filled with demonic energy. It was too strange to think that the formation was a formation constructed by the demon clan. You must know that in my opinion, this formation was built at least three thousand years ago." Elder Xu Chensheng's face became quite strange.

Chang Wei was shocked when he heard this: "Have you ever such an amazing person from the demon clan? Can such a powerful formation be set up? Can you still trap the existence of the Nascent Soul Realm in 3,000 years?"

Tang Jiuqu was also shocked: "If a large array has no energy input, it will generally be destroyed in a hundred years. Even if there is continuous energy input into it, if no one maintains it, it will last for a hundred years. If this large array really has a history of 3,000 years, then the owner of this large array will be too powerful."

Xu Chensheng reached out to break through the sea water in front of him, and built a vacuum channel in the sea. He descended all the way, and his clothes fluttered, and said, "I don't know much about what the world was like 3,000 years ago. Maybe there was really a powerful demon clan. If we could break through this ancient formation, there might be some clues."

While speaking, the four people had already arrived under the deep sea. It was pitch black and silent. The sea water was extremely cold, but the water flow was quite surging. A stream of water hit the four people. Fortunately, the four people had a high cultivation level and did not care about the surging and cold current.

Tang Letian looked down and with his eyesight, he could only see gullies at the bottom of the sea, and a bottomless trench was like a pitch-black dragon entrenching among the gullies.

Elder Xu Chensheng led the three of them to leap into the trench.

The three continued to dive, but this time they didn't go deep into the trench for too long, so Elder Xu Chensheng stopped.

Tang Letian indeed found a huge black hole on the steep trench cliff. It was about 20 meters wide and narrow. Even in this dark trench, it still gives people a feeling of being as deep as if they were to suck human souls in.

Chang Wei and Tang Jiuqu's expressions changed slightly. With their cultivation level, they could keenly feel the threat brought by this black hole. Streams of demonic aura surged out of the black hole. Although they were invisible, they could feel the rough feeling of demonic aura rubbing on their skin.
