"It's raining!" I subconsciously reached out my hand, and dense raindrops fell into my palm.

In just a moment, a torrential downpour swept through the mountain area, and the sound of rain surrounded the Seated Buddha Stone. The four of us stood motionless.

A sudden downpour in the mountains might seem like unpredictable weather to ordinary people. But a warlock looks at the rain with more scrutiny. At the very least, we have to figure out whether the rain is chasing us, or we're trying to avoid the rain.

If the rain is chasing us, it means that some mountain spirit is deliberately trying to make us panic and take a wrong turn, leading us to a pre-determined location. There's bound to be something waiting for us there to take shelter from the rain.

The rain above our heads was not only sudden, but it kept swirling around the four of us, like flowing water. The raindrops kept washing over the Seated Buddha Stone, and the moss covering the stone Buddha's face began to peel off in patches.

Before long, the eyes and brows of the stone Buddha, which had been suppressed by the moss, appeared before us.

Even in the downpour, the tears rolling from the stone Buddha's eyes were unusually clear. I could even distinguish which drops were raindrops and which were tears.

Ye Yang said in a deep voice, "The stone Buddha weeps, a demon is born. Someone has opened the seal before us."

As Ye Yang spoke, my eyes scanned the surroundings several times. "The rain over there is not right!"

I could clearly see that about ten steps away from me, there was an exceptionally thick stream of water. At first glance, it looked as if the rain was falling on something that was wide at the top and narrow at the bottom, and then concentrating at one point as it fell to the ground.

Ye Yang stepped forward and lightly raised his sword. The moment the invisible sword energy pierced through the air, it was as if some kind of restriction had been broken. The scenery around the stone Buddha suddenly shattered, revealing five long swords suspended from the tree trunks.

I don't know how many years those five swords had been hanging there, the blades were already covered in rust, but the inscriptions on the swords were still vaguely visible.

Feng Ruoxing muttered softly, "Nine Swords Inverted to Suppress the Heavenly Coffin; Demon or Buddha, a single thought can define. The last two lines… it seems like someone scraped off the last two lines.”

"No, the long sword with the last two lines was taken away." Ye Yang said in a deep voice, "These nine swords are the keys to open the underground prison. One of them belongs to the jailer. The remaining eight should be divided into two groups, corresponding to two different gates."

"Bai Hanfei and the others came up and took four of them, leaving us four!"

Ye Yang paused. "The four swords that Bai Hanfei took are here…"

Ye Yang swept his foot across the ground in front of the Seated Buddha Stone. The rain-soaked soil was immediately overturned by Ye Yang, revealing an area the size of a tabletop, also exposing four sword boxes buried beneath the soil.

As I looked at the four sword boxes, Ye Yang's fingers, hanging by his side, twitched slightly, and a burst of sword cries came from the sword boxes.

Ye Yang was using Qi to guide the sword?

Ye Yang said in a deep voice, "Li Po, it's time for you to make a decision. If you choose to seal the swords before the Buddha, then we will seal the remaining four long swords in the same way, and follow the path that Bai Hanfei took to the underground prison."

"If we don't want to take this path, we still have another path to take. That is a bloody path!"

I walked to one of the suspended swords and gently tapped it. The sound of a dragon's roar immediately resounded through the mountain forest. I stared at the slightly trembling long sword and said, "Is this sword a spirit key?"

The so-called spirit key is the pinnacle of a locksmith's art.

A true locksmith, is said to be able to seal the gates of hell and lock up heaven and earth with a single miraculous lock. The keys to open secret locks are even more varied. The truly ultimate secret locks often have no keys at all.

Because the spirit key crafted by a locksmith may be a stone, a leaf, or even a gust of wind or a rainstorm.

Wherever there is a Zhenyu (prison) or a mausoleum, there will definitely be the presence of a locksmith.

The miraculous locks they create are the most difficult defense to break in the Zhenyu (prison) and the mausoleum.

I said with my hands behind my back, "One person in a grave becomes a mausoleum. Several people in a grave are called a Zhenyu (prison)."

"A prison is still a prison. What does this have to do with 'a single thought can make you a Buddha or a demon'?"

Feng Ruoxing nodded, "I think what Li Po said is the key."

Ye Yang said in a deep voice, "A prison, in a sense, is not a dead end from which there is no return. Rather, it is a place where prisoners can reform themselves."

"Becoming a Buddha means choosing to redeem the prisoners in the prison."

"Becoming a demon, of course, is simple; it means slaughtering the entire prison."

Ye Yang looked at the long sword again and said, "I think the person who designed this prison back then seemed to have other intentions. At least, I now think that he is testing the person who opens the prison door."

If I want to find Bai Hongzhen's Earth Soul, I have to go down to this prison.

However, all the clues related to this prison have been cut off. The two jailers, are of unknown status. Bai Hanfei went into the Zhenyu (prison) before me, sweeping away most of the clues on the outside.

Choosing to go down to the Zhenyu (prison) at this time is like forcing my way into a secret realm.

If I don't go down, how long can Ye Yang and I's lifespans last? Maybe we won't be able to wait for the next Yin Si (Underworld) secret order!
