He had been immersed in the art of formations for many years, but had never seen such a strange combination of runes. He couldn't help but feel a desire to explore.

"Interesting..." Chen Yang's mouth curled up with a playful arc. It seemed that the things behind this stone door were becoming more and more interesting.

He sat cross-legged, took a deep breath, circulated the spiritual power in his body, and slowly probed his spiritual consciousness into the runes on the stone door.

These runes were like living things. The moment his spiritual sense touched them, they seemed to be awakened and trembled violently. A powerful recoil force instantly hit Chen Yang, causing him to groan and his face to turn slightly pale.

"What a powerful restriction!" Chen Yang was secretly shocked. This restriction was several times stronger than he had imagined.

Seeing this, Li Qingge quickly stepped forward and asked with concern, "Mr. Chen, are you okay?"

Chen Yang waved his hand to indicate that he was fine, but he became more cautious in his heart.

He had just refined the Nine Palace Formation, and his spiritual power had greatly increased. He thought that breaking the restriction would be a piece of cake, but he did not expect to encounter such a strong obstacle.

It seems that opening this stone door is not easy.

He calmed his mind and probed his spiritual sense into the rune again.

This time, he was no longer in a hurry to achieve success. Instead, he carefully felt the power fluctuations in the runes and carefully analyzed the structure and trajectory of each rune.

As time went by, beads of sweat gradually seeped out of Chen Yang's forehead, but he was completely unaware of it and was completely immersed in the world of runes.

Li Qingge on the side looked at Chen Yang quietly, his eyes full of worry and curiosity.

Chen Yang's focused expression when he broke the ban, as well as the strong confidence and composure he exuded, deeply attracted her.

She had never seen such a special man. Although he was so young, he possessed such powerful strength and reassuring demeanor.

Li Qingge couldn't help but wonder, where did Chen Yang learn his skills from? Why did he have such powerful strength at such a young age?

Could it be that he is the heir of some hidden sect?

Thinking of this, Li Qingge became even more curious about Chen Yang's origins.

As for Chen Yang's constant claim that he was a casual cultivator, she naturally treated it as a joke.

He understands pharmacology, can wield a sword, and can defeat monsters in the late stage of foundation building when he is in the early stage of foundation building.

Now I also understand the formation!

Not to mention the independent cultivators, even the old Nascent Soul monsters she had seen in her family did not have such nearly omnipotent means!

Time passed minute by minute, and the cave was silent.

Only the occasional slight breathing sound of Chen Yang and the faint light flowing between the runes proved the passage of time.

Finally, after an unknown amount of time, Chen Yang's tightly closed eyes suddenly opened, and a gleam of light flashed in his eyes.

"I see……"

The corners of his mouth rose slightly, revealing a confident smile, and he whispered.

“Found it!”

As soon as he finished speaking, he quickly formed seals with his hands, and mysterious runes flew out from his fingertips and merged into the runes on the stone gate like elves.

Buzz!

The runes on the stone gate suddenly shone brightly, powerful spiritual energy fluctuations came from the stone gate, and the entire cave began to vibrate violently.

"It's about to open!" Li Qingge was delighted when he saw this. He quickly took a few steps back and stared at the stone door nervously.

The stone door made a deafening roar and slowly opened inward.

Strong light gushed out from the crack in the door, as if a giant beast that had been sleeping for thousands of years had opened its eyes.

Chen Yang subconsciously protected Li Qingge behind him. He did not stretch out his hands to block the light. Instead, he focused his spiritual energy on his eyes and forced himself to open them to look into it.

This place is very likely to be an ancient place. If there is any mechanism in it, covering my eyes now is the same as losing my life.

When the light gradually dissipated, Li Qingge behind Chen Yang opened his eyes and saw the scene behind the stone gate clearly.

“This… How is this possible?!”

Li Qingge covered his mouth in surprise, his eyes full of disbelief.

Behind the stone door was not the secret room or treasure house they had expected, but a long and deep passage.

The walls on both sides of the passage are covered with ancient and mysterious murals, emitting a faint green light, as if silently telling the secrets of ancient times.

"Don't be afraid, follow me." Chen Yang whispered, with a hint of tenderness in his tone that he himself didn't even notice.

He summoned the Seven Deadly Swords, and the sword emitted a sharp cold light, illuminating the road ahead.

The passage was silent, with only the footsteps of the two people echoing in the empty space, adding a bit of eerie atmosphere.

The two walked forward cautiously, their eyes constantly scanning the surroundings.

The content of the murals is obscure and difficult to understand, with all kinds of strange creatures and symbols intertwined together, as if telling an ancient and mysterious story.

"These murals... seem to be some kind of ancient secret. Unfortunately, I don't know much about it." Li Qingge frowned and said with a hint of regret in his tone.

Chen Yang smiled faintly: "It doesn't matter, even if it is really a dangerous place, I, Chen Yang, will still go in."

Although his tone was calm, Li Qingge could sense the strong confidence in his words.

For some reason, Li Qingge's originally uneasy heart calmed down at this moment.

Just like a young boy admires beauty, a young girl also secretly has feelings of love in her heart.

"Mr. Chen is so courageous!" Li Qingge covered her mouth and chuckled, with a strange light in her beautiful eyes.

"However, Master Chen, please be careful. There are strange things everywhere here. I'm afraid..."

Before she could finish her words, Chen Yang suddenly stopped and stared coldly ahead.

Li Qingge was startled and looked in the direction he was looking, then he took a deep breath.

Not far ahead of them, a skeleton suddenly appeared in the middle of the passage!

The clothes on the skeleton had long since decayed away, but judging from the shape and size of the bones, the person must have been a male.

The skeletal hand tightly grasped a rusty iron sword, maintaining the posture of struggle before death.

"It seems that we are not the first people to enter here."

Chen Yang squatted down and carefully observed the bones, frowning slightly.

"Judging from the posture of this skeleton and the scars on its body, he must have died from some powerful attack, and..."

He paused, his eyes falling on the obvious sword mark on the opponent's chest skeleton, and a cold light flashed in his eyes.

"I don't know how much time has passed, but there's still a faint trace of spiritual energy fluctuation remaining on this wound."

Li Qingge was startled when he heard this.

Chen Yang gently placed his palm on the sword mark on the bones, and a faint wave of spiritual power flowed into his body along his fingertips.

Although it is unknown how long this spiritual power has been around, it is still strong.

But it is extremely complicated, with a cold and eerie atmosphere, like a poisonous snake spitting out its tongue, which makes people shudder.

"Such a domineering spiritual power, it actually carries such a strong corrosive force."
