Just as they were talking, a few flashes of silver light suddenly flew towards them, and Ji Youfei shouted: "Dodge!"

  Mo Zi Chen dodged to the right, and the light enveloped her body, making her tense all over. She hurriedly tried to immerse her mind into the jade pendant, and after the previous move, she seemed to have gradually grasped the usage of this jade pendant.

  As expected, the jade pendant emitted a soft glow again, just like last time. It was as if it were a starving monster that swallowed all the spiritual energy around it. The few rays of light that swept across her body disappeared without a trace afterwards.

  But this time, after Yu Pei absorbed the light, she didn't immediately withdraw, but instead seemed to sense something and emitted a soft layer of light around Mo Zi Chen, enveloping her.

  Ji Youfei said, "It seems that there is some sort of formation around here, which was triggered by us just now. Judging from this, under the ancient tomb, there must be a very large prohibition formation array. What we triggered is only the first gate of the formation. It's better to turn back."

  Mo Zi Chen's courage grew at this time, she felt that the white light around her was protecting her, and it seemed as if she couldn't feel the breath of the surroundings. The current feeling is very strange, just like she has already left the world behind and has nothing to do with everything around her.

  She took a look at the talisman paper Yu Wei gave her, and the light on it hadn't dissipated, obviously they had another way. She hesitated for a moment, then said: "If we go back and meet that demon again, what should we do? With the protection of this treasure, I think we can pass through this formation directly, why don't we try to see. Going back is waiting for death, moving forward, who knows if we can still find a way out."

  "Alright!" Ji Youfei raised an eyebrow.

  Mo Zi Chen reached out and took his hand, feeling a warm energy emanating from the palm, which was not as rough as most men's.

  That white light enveloped both people at the same time and slowly walked forward.

  As they walked to this place, the path also became much wider. Ji You flew over and said: "This path seems to be winding down all the way, we are now at least hundreds of feet under the belly of the mountain. I didn't expect that under this mountain peak, there was actually another cave heaven. Looking around at the stone walls, they were not naturally formed, but must have been excavated by someone with great magical power in those years."

  The stone walls around were not smooth, but there were obvious axe marks, and moss grew on them, looking like they had been through many years. It was obviously a man-made passage. Every ten or so zhang away, you could even see the remains of candle holders. Only after experiencing the changes of the seasons, it was probably long abandoned.

  "Could this really be a relic of an ancient battlefield?"

  Ji Youfei said: "Years ago, I followed my master to the Ninth Heaven Spirit Gorge Peak. That was where several powerful demons and the Xuanmen ancient cultivators had a great battle many years ago. Although it has been countless tens of thousands of years, the killing aura there is still palpable everywhere. I only made it through the first gate before retreating because I couldn't withstand it. Only Yuan Ying cultivators can enter the Ninth Spirit Gorge and withstand the killing aura inside. If this really is an ancient battlefield, we would have been annihilated long ago."

  "According to your words, this is not something that an ordinary cultivator can build."

  Ji Youfei said, "Perhaps it was the residence of a certain Demon Lord back then, who knows. To think that in ancient times, those great demon heads had powers far beyond our imagination, at least during that time, ascending to immortality wasn't as difficult as it is now. With countless heavenly treasures and earthly gems, it's not strange that they could open up a cave like this."

  Mo Zi Chen thought of the place he had seen in the valley, his eyes shining brightly as he asked: "Since it's such a cave, there must be hidden treasures, right?"

  Ji Youfei smiled wryly and shook his head: "That's not necessarily true, if it's really the ancient cave of Xuanmen, that's one thing, but if it's left behind by some big demon king, I'm afraid we won't be able to take any treasures even if there are any. Let's go step by step and see."

  After the recent array activation, the surrounding scenery changed in an instant, and the corridor gradually widened. The walls were also carved with strange patterns and murals, depicting various bizarrely dressed men and women wearing exquisite clothes, performing a flying celestial dance, breathtakingly beautiful.

  Ji Youfei had already put away the dagger at this time, and his voice unconsciously lowered: "This treasure of yours is truly extraordinary, it can actually gather all of a person's aura. A single move, isolating everything outside. We've been walking for a while now, yet not a single array has been triggered."

  He pointed around with his fingers, "You see there, and there, they are all the eyes of the formation. As long as the cultivator comes here, he will trigger the mechanism."

  He was saying this when Mo Zi Chen suddenly said: "We've reached a dead end!"

  Ji Youfei raised his head, only to find that he had unknowingly stood in the middle of an octagonal stone chamber. The chamber was divided into eight corners, each with a passageway, and they had come from one of them. The entrances of the other seven passageways were shining brightly, leading to unknown places.

  Suddenly, a strange feeling surged in Mo Zi Chen's heart: "Those two, won't they also come here?"

  Ji You flew shook his head: "Don't you feel it? The other seven channels all end in death!"

  Mo Zi Chen was taken aback.

  Ji Youfei said in a deep voice: "This is the Eight Gates of Golden Locks, only one gate is the Gate of Life, and the rest are all Gates of Death. The path we take is the only Gate of Life among them."

  "What should we do now?" Mo Zi Chen said.

  "Eight Gates Golden Lock, the array eye must be there." He hesitated for a moment, "Mo Niang, do you dare to make a bet with me?"

  Mo Zi Chen smiled: "No need to be so polite, you can just call me Little Mo. Since we've come this far, why not take a chance and go all out?"

  "Alright, withdraw your magic tool."

  Mo Zi Chen withdrew the light of the jade pendant, and suddenly felt dizzy. The spiritual energy here was more than ten times thicker than outside, and she almost couldn't adapt at once.

  "Then I can repair my Beidou Sword Marbles as soon as possible," Ji Youfei said with a smile. He released the seven Beidou Sword Marbles, which revolved around his head, forming a formation that seemed to have a spiritual aura, resembling the Big Dipper constellation, with his body as the center, rapidly rotating. The surrounding spiritual energy also seemed to be responding, surging towards this place. Originally dimly lit, the Beidou Sword Marbles absorbed the spiritual energy continuously and emitted silver sword light again. Seven beams of light converged into one, suddenly bursting upwards, condensing into a giant sword several meters high, slashing straight down towards the ground.

  A loud "bang" sound, apart from the door they came in, seven other doors shattered simultaneously. Ji You Fei shouted: "Rise!"

  The ground turned into an octagonal disc and exploded with a loud "bang" in all directions. The underground was like an ancient well, almost bottomless.

  The two lowered their heads and looked down, clicking their tongues: "This... is a spiritual vein?"
