Mysterious mirror hanging high

Ku Du's Xuan Guang was activated, and the rock layers melted away when they encountered the Xuan Guang. Jing Yu instantly cleared a vacuum spherical area around them.

He looked at the jade ore dotted on the rock wall, picked up a piece at random, put it in his mouth to taste it, chewed it a few times and swallowed it.

"It really is a spirit stone... and a rare Jade Spirit Stone."

The spiritual stones between heaven and earth naturally have various properties. Generally speaking, most of the spiritual stones circulating in the world of immortal cultivation are [attributeless spiritual stones] that can be used by any cultivator.

This kind of spiritual stone has no special properties. The spiritual energy contained in it is the most gentle and even, the most versatile, and the largest in output, and is deeply loved by monks.

However, its wide versatility means that it is not specialized enough. If there are special requirements, spirit stones with special properties will be needed.

The most common of them is naturally the Five Elements Spirit Stone. Others like [Wind Spirit Stone], [Thunder Spirit Stone], and [Ice Spirit Stone] are all derived from the Five Elements.

This [Jade Spirit Stone] is a small branch of earth-type spirit stone. It is not common in the world today. It can only be used by practicing jade-related skills or magical powers. Unexpectedly, a large vein of ore was discovered here.

"But the quality of this spirit stone is average. It's just an ordinary low-grade spirit stone. It doesn't even have a hint of mid-grade quality." Jing Yu muttered.

Generally speaking, a spiritual stone vein like this one, which is entirely of low-quality on the periphery, is not worth very much. There may be traces of medium-quality spiritual stones in the deep part, and at most a few high-quality spiritual stones can be dug out near the center. For Jing Yu's current wealth, it is better than nothing.

In fact, there are quite a few naturally formed spirit stone veins in the endless underground of the major immortal continents, but the reason why no one is interested in them is because of the mining costs.

Low-level cultivators who are training Qi and building their foundation cannot carry out conventional excavation in this area. Although Yuanying Zhenjun can escape into the void and go deep into the ground, it is still time-consuming and laborious to mine all the spirit stone veins.

With this spare time, perhaps Yuanying Zhenjun could get a magical medicine or a magic weapon at random in some wild land or secret cave, and its value could be equivalent to this spiritual stone vein.

Naturally, Jing Yu couldn't mine the entire vein, so he continued to go deeper into the vein, intending to mine the best quality area in the core of the vein, and then stop and leave.

He continued to urge [Ku Du Xuan Guang] to explore inward, but suddenly seemed to touch something and let out a light exclamation.

"This is?"

Before reaching the center of the vein, Jing Yu encountered a wall. The wall looked like gold but not gold, and like stone but not stone. It seemed to be a special spiritual material, but it was obviously not made of earth or stone. Ku Du Xuan Guang could not penetrate it for a while.

Fortunately, Ku Du Xuan Guang not only has a miraculous effect on soil and rocks, but it is also an extremely advanced magical power of light. After continuous wear and tear, Jing Yu also melted a big hole in the wall of unknown material.

Passing through the hole created by [Ku Du Xuan Guang], Jing Yu felt an extremely pure and rich inspiration rushing towards him, and his eyes suddenly became clear.

A green jade disk over a hundred feet high stood before him, its surface engraved with Buddhist Sanskrit characters, the writing inlaid with jade spirit stone marrow, emitting a bluish-white glow in the darkness.

The bottom of the jade disk is covered with mineral veins, and the exposed spiritual stone veins are coiled like tree roots, forming a natural staircase.

There are twelve green jade arhat statues on both sides of the stairs, some of them are holding pestles with angry eyes, and some are chanting scriptures with lowered brows. The surface of the statues is covered with a layer of crystal spirit stone crystals, like a cassock condensed from green jade.

Jing Yu stared at everything in front of him, stunned: "There's actually an underground palace tens of thousands of miles underground in Futu Xianzhou?"

He stepped forward and looked at the twelve jade Arhat statues, and understood clearly:

"I see!"

These twelve green jade arhats are not sculptures, but objects manifested from twelve [spiritual veins]!

Jing Yu understood instantly that the reason why such a spirit stone vein was formed outside the underground palace was probably because of the spiritual energy that escaped from the underground palace over the years.

"A full twelve spiritual veins were placed here to enrich the spiritual energy in the underground palace?"

Jing Yu immediately guessed the purpose of the green jade arhat statue. It must have been placed there intentionally by a high-level cultivator in order to make the concentration of spiritual energy in the underground palace reach the standard for cultivation.

With these twelve high-quality spiritual veins fixed here, the spiritual energy of this underground palace is so rich that it has reached the level of a Nascent Soul Dojo, which is enough to provide daily practice for cultivators below the God Transformation stage.

Jing Yu marveled at the green jade arhat statue, but was in no hurry to take it. Instead, he walked towards the green jade disk.

The green jade disk was engraved with Buddhist Sanskrit. Jing Yu was well-read and his knowledge was considered profound among Yuanying Zhenjun. Naturally, he knew some Sanskrit. He glanced at it briefly and his expression became strange:

"Is this a manifesto?"

Moreover, the content of the manifesto also surprised him a little.

Because this is a manifesto against the [Shending Xianchao]!

The gist of it is that the Immortal Emperor Shending is licentious, perverse, cruel and inhumane... causing the cultivators and people all over the world to suffer terribly.

We, the Buddhist disciples, should raise high the banner of justice, overthrow this unjust dynasty, and restore the glory of Buddhism.

"Or is it the Buddhist sect's manifesto against the Divine Cauldron Immortal Dynasty..." Jing Yu muttered to himself, "How many years has this underground palace been buried here?"

You must know that it has been more than 100,000 years since the [Middle Ages] when the Shending Immortal Dynasty ruled the Immortal Continent!

He suddenly thought of a possibility.

The depth of the ground where he is now is too deep. Even a Nascent Soul cultivator would find it difficult to move forward if he is not proficient in earth escape. What kind of powerful person can dig and build such a magnificent underground palace so deep underground?

Perhaps the monks who built the underground palace did not build it at this depth.

But after more than 100,000 years, perhaps due to changes in the earth's veins, the underground palace slowly sank here.

If Jing Yu had not tried to avoid Xiao Guanying's possible pursuit, perhaps no one would have discovered this underground palace.

Jing Yu sighed at the power of time, walked past the jade disc, and headed towards the main hall deep in the underground palace.

Entering the main hall, the view becomes wider. A relic lamp is hung on the dome of the main hall. I don’t know what material this lamp is made of, but it has been lit for more than 100,000 years.

The main hall leads to various side halls, including the Sutra Library where books and jade slips are stored, the Zen Cave where disciples can meditate, the Dharma Platform where disciples can practice magic and supernatural powers, and the Alchemy Courtyard where elixirs are stored.

Jing Yu first walked into the [Scripture Library] and soon saw rows of bookshelves, which contained tens of thousands of jade slips. Perhaps because each row of bookshelves had special protective restrictions, these jade slips were all intact.

Jing Yu casually picked up some jade slips from the bookshelf and read through them, and immediately understood the origin of this underground palace.
