"Can't that mysterious man be a master in the Venerable Realm?" Qin Yu said with a slight look on his face, a little worried.

But the earth-center demon flame is right in front of you, and Qin Yu cannot give up so easily. Besides this earth-center demon flame, it is impossible to find a second spiritual flame that can allow Qin Yu to advance to the fifth-grade spirit flame master in the entire area radiating to Wangu City.

"No matter what, go in first and then take a look. Moreover, no one knows the structure of this Qianyuan Ancient Formation better than me. If you really encounter a master in the Venerable Realm, you can use it to escape."

Qin Yu weighed it for a moment and ordered: "Yige, take us in."

"Hmm? It seems that this little beast will not give up until it gets the Earth-center demon flame. Haha, okay, I will use the Qianyuan Ancient Formation to kill you in a while."

Yi Ge said coldly in his heart, but he said respectfully on the surface: "Okay, okay, I'll take you in now."

The three of them stepped into the demon cave in the earth, as if they had entered an unfathomable abyss. A group of violent black winds passed by the ears of several people, like steel knives, falling on the faces of the three people, with a scorching pain.

"Our Yi family has arranged the Qianyuan Ancient Formation below to isolate most of the demonic energy, so the one that blows out the cave is just ordinary demonic energy, which can erase any warrior in the Tianhe Realm, but it will not cause any damage to the warrior in the Wheel Sea Realm."

After entering the Earth-Central Demon Cave, Yi Ge's attitude became unexpectedly gentle, often solving doubts for Gu Yuan and Qin Yu, and led Qin Yu to a place a hundred meters below the Earth-Central Demon Cave.

Within this hundred meters, energy fluctuations formed a hole of dozens of meters, and enough people passed by side, which was exactly the ancient formation of Qiankun arranged by the Yi family.

"This is the ancient formation of Qiankun of your Yi family, it is indeed extraordinary." Gu Yuan couldn't help but be surprised when he looked at the halo around him.

The halo formed by the ancient Qiankun formation is faintly yellow, but its power is extremely powerful, resisting most of the demonic energy evaporated from the bottom of the Earth's Demon Cave.

Even though some of them pass through the ancient Qiankun formation, their power has been reduced a lot, and they can only cause crisis for warriors below the Wheel Sea Realm.

"Haha, yes, in order to arrange this ancient Qiankun formation, our Yi family spent countless treasures to achieve this today. Moreover, the ancient Qiankun formation is about to be completed. At that time, as long as Mr. Qin is willing, he can easily take away the demon flames in the center of the earth." Yi Ge said with a smile, with an extremely kind attitude.

If someone who didn't know would think the relationship between the three was very good, but in fact, Yi Ge had already hated the two of them and wanted to tear Qin Yu and Gu Yuan apart one by one.

"Mr. Qin, this is just the outermost end of the ancient Qiankun formation. If you want to enter the real interior, you need the ban token refined by our Yi family. I have three of them here, just enough for us to use them." Yi Ge said, taking out three tokens from the storage bag.

These three tokens are not big, only the size of a palm, and look extremely ordinary, but they reveal a terrifying fluctuation.

"Haha, Yige, if you cooperate with Mr. Qin and me early, you wouldn't be ruined and cultivated." Gu Yuan took the ban token the size of a palm, said with a big voice, and hung it around his waist.

When Yi Ge heard this, his face twitched, and a trace of resentment flashed deep in his eyes, but it was quickly covered up by him, and a smile forced out on his face.

Qin Yu also took the ban token, but it did not hang it directly on his waist like Gu Yuan. Instead, he played with it for a while and hid me in his sleeve robe.

After obtaining the ban token, the three of them entered directly inside the Qiankun Ancient Formation, followed the passage isolated from the ancient formation, and entered the depths of the Earth's Demon Cave.

However, although it is protected by the ancient Qiankun formation, the three of them still encountered a lot of trouble along the way.

Qin Yu's hand moved faintly, and a golden light shot out from Qin Yu's hand, easily killing a black cow-horned monster, completely shattering it.

After that, Guyuan also killed a monster.

"What's going on? Isn't there a guardian of the ancient Qiankun formation here? Why are there so many monsters appearing?" Gu Yuan said with some dissatisfaction.

Although these monsters only have the cultivation level of the eighth and nineth level of the Tianhe Realm, they do not pose any threat to Qin Yu and others, but too many of them have caused some inconvenience to the actions of the three.

"Don't be angry, Lord Guyuan, these monsters in the Earth's central demon cave are numerous and countless. They often attack us, but as long as we kill them all the way, there will be no problems." Yige hurriedly explained.

Gu Yuan frowned and looked a little slow. They killed all the way. This was indeed not a problem, but it was too troublesome and he was quite helpless about it.

"Haha, this old guy is still pretending. I want to see when you can pretend to be." Qin Yu sneered in his heart at this time, obviously not believing Gu Yuan's words.

The few people went down the road and encountered many monsters, but as Yige said, these monsters were just low-level monsters and did not pose any threat to them.

At this time, everyone had already entered the Earth Demon Cave for a day and a night, and was only a few hundred meters away from the bottom of the Earth Demon Cave.

"Mr. Qin, we are about to arrive. Below is the place where the earth's demon flame is." Yi Ge hurried forward and walked a few steps, pointing a hundred meters away and said.

Qin Yu and others followed Yi Ge's guidance and looked around. Wherever there was a burning black spiritual fire, releasing a terrifying force, constantly burning, making the surrounding air extremely hot.

"Demon Flame of the Earth!"

Qin Yu's eyes moved slightly, and the black spiritual fire was indeed the demonic flame of the earth's center, and the burning void was constantly shattering.

"Haha, Young Master Qin, the demon flame in the center of the earth is right in front of you, hurry up and collect it." Gu Yuan said with a smile, a hint of envy rose in his eyes.

The power of this earth-center demon flame is so terrifying that it can not only be used to refine medicine, but also to kill enemies. It is a rare treasure.

"Okay, watch this old dog, I will come out after I go down to collect the earth-center demon flame." Qin Yu nodded and stepped out, and came to the earth-center demon flame, preparing to collect the earth-center demon flame.

At this time, in a dark corner, a pair of eyes opened, looking at Qin Yu with a vicious intent, boiling murderous intent.

"Little beast, the moment you touch the demonic flame in the earth's heart is your death." Yi Ge's face suddenly became ferocious.

"boom!"

Just as Qin Yu was about to touch the demon flame in the center of the earth, a strong murderous intent wave immediately emerged from behind. The terrifying aura made people suffocate. At the same time, a black light hit Qin Yu's back.
