Holding the black iron spear, Nightshade struck at the wall, and with the knocking, the stone wall made a crisp sound, and the stone powder did not fall, and no trace appeared, which made Nightshade know how hard the stone wall was.

At the same time, it also made Ye Di understand that the predecessors who dug this cave at the beginning had cultivated to an unfathomable point.

Turning his head to see the white bird quietly following him, flapping his wings from time to time, Nightshade knew that there was no danger in this cave.

Demon beasts generally have a stronger intuition for danger than humans, and now that Shiratori is so quiet, it means that there are no powerful demon beasts in this cave, at least there are no demon beasts that suppress Shiratori in terms of level.

Carrying the black iron spear, Nightshade slowly advanced, although it was certain that there were no high-level demon beasts, but Nightshade was worried that there was something to trap, which the monsters could not perceive.

After advancing a distance of three or four zhang, a stone chamber with a radius of three zhang appeared in front of Ye Di's eyes.

There are stone tables and stone chairs in the stone room, and when he continues to look inside, he sees the scene and makes Nightfall involuntarily take a step back.

There is a skeleton on the seat in the table, the robe hanging on the skeleton has been weathered, and the tattered robe is on the skeleton one by one.

After settling his mood, Nightshade walked over to the table and examined the bones carefully.

This skeleton was a little different from the bones seen in the previous nightfall, this skeleton was full of luster, like jade, and there was no trace of damage.

Looking at the bones, Nightshade could determine that the owner of this skeleton was very tall in life, six feet tall, and even if he died, the skeleton was still full of domineering when he sat there.

As Nightshade approached, the airflow brought up made the robe on the skeleton completely weathered and turned into ashes, and the skeleton was completely exposed to Nightfall's eyes.

Nightshade bowed to the bones, he didn't believe in ghosts and gods, but entering this cave was a disturbance to the bones' long sleep.

Straightening up, Nightshade found some handwriting on the table in front of the skeleton.

The handwriting should have been written with a finger, some scribbled, but it was deeply engraved on the stone table.

In a different position, Nightshade lowered his head and blew the dust on the table, and the robe on the skeleton was weathered, staining the table with some dust.

Looking closely, Nightshade found that the last words left by the bones were on it, as well as some of his own life.

The name of the skeleton before his death was Feng Chen, and he was the elder of the Medicine Valley guarding Taichuan, Taichuan! Night Death frowned, he had never heard of this name, could it be the bottomless canyon in front of him?

Then the following record explains the cause of Feng Chen's death, he was because of the outbreak of Taichuan's netherworld qi, went to investigate, and met the Netherworld Beast King, after killing the Netherworld, he was also contaminated with Netherworld, and he couldn't get rid of Netherworld, and finally died.

Feng Chen's last words were to let the destined people return the Holy Ding Sutra to the Medicine Valley, when he was stationed in Taichuan, he took the Holy Ding Sutra of the sect, hoping to enter the legendary Holy Realm, but it was unsuccessful, hoping that the destined people would return the Holy Ding Sutra to the Medicine Valley, and all the other proceeds were left in the destined people.

Seeing these three words, Ye Di was extremely shocked, isn't the Holy Ding Sutra the treasure book of the Zhen Sect in the Medicine Valley? Looking around, Ye Di didn't see where the Holy Ding Sutra was.

But Feng Chen said that if someone is destined to return the Holy Ding Sutra to the Medicine Valley, then the Holy Ding Sutra must exist, but Ye Di searched in the stone room for a long time and did not find the Holy Ding Sutra.

Could it be that someone came and took the Holy Ding Sutra away? However, Ye Yan felt that this was unlikely, and the robe on the bones was only weathered when he came in.

Looking at the skeleton again, Nightshade noticed the skeleton's ring finger, which had a silver ring on it.

Storage rings!

Nightshade heard from the ancient father that in the outside world, high-end cultivators would use storage rings, which were a special magic weapon, and there was a Sumeru space inside to store things.

Thinking of this, Nightshade bowed to the skeleton and took the ring off.

Took the ring and looked through it, but didn't see the name, Night Death bit his finger and dripped a drop of blood on the ring, many treasures need to be dripped, and there is still a little common sense Night Death.

The blood dripped on the ring, and it was quickly absorbed by the ring, and at this time, the night who watched the ring had a kind of enlightenment, and felt that there was a connection with the ring.

It's really a storage ring, and as soon as the idea of Nightfall moves, a special space appears in Nightfall's mind.

The special space is three zhang square, with shelves on both sides of the space, and a wooden table in the middle, on which this stack of classics is neatly arranged.

As soon as the thought turned, Nightshade took out all the books.

The first is the Holy Ding Sutra, which has three ancient characters written on the ancient paper, which is the Holy Ding Sutra.

This is the town school classic of Medicine Valley, the Holy Ding Sutra!

Night Death was a little excited, picked up the classics and began to read, the first chapter is the Xuanding Sutra, after reading it, Night Death found that it was exactly the same as Gong Xuan gave himself.

This made Ye Di sure that this was the Holy Ding Sutra, the classic of the town sect of Medicine Valley.

Put this book down and go to the second book at Nightfall.

The second book has three words written on it, and after opening it, Night Death carefully studied it, and he found that the stunt of the Taixuan Peak Peak Lord's famous Heaven Shaking Hand was only a part of the Heaven Covering Hand, this Heaven Covering Hand was created by Feng Chen's own hand, and there was no need to return it to the Medicine Valley.

The third book is much older than the first two, and the name of the book is the Book of Ten Thousand Paths.

Nightshade opened the Book of Ten Thousand Dao Treasures, and a piece of animal skin floated out in the middle, and there was handwriting on the animal skin.

Picking it up and looking at it, Nightshade knew the origin of the Ten Thousand Dao Treasure Book.

The Ten Thousand Dao Treasure Book was obtained by Feng Chen in Taichuan, and some of Feng Chen's own opinions were written on the animal skin. The essence of the Ten Thousand Dao Treasure Book is to use the body as the tripod, and the true qi running route is almost the form of the tripod, and the cultivation to the extreme can be transformed into the tripod;

Feng Chen's view is that the Ten Thousand Dao Treasure Book is much stronger than the Holy Ding Sutra, but his Holy Ding Sutra has a deep fire, and the gain of cultivating the Ten Thousand Dao Treasure Book outweighs the loss, so he is determined to break through in the Holy Ding Sutra, and finally because he was invaded by the Netherworld, he died.

Putting away the Ten Thousand Dao Treasure Book, Night Death opened another book, this is the Spiritual Object Illustrated Book, which records all the herbs, poisonous weeds, minerals, demon beasts and spirit beasts in the world.

The last one is a codex, it is an alchemy codex, it is Feng Chen's synthesis of other alchemy classics, the Dan Sutra written by himself, these night deaths can figure it out, Medicine Valley is famous for alchemy, as the elder of Medicine Valley, Feng Chen's attainments in this area must not be low.

Nightshade closed his eyes and sorted out his emotions for a moment, then put a few books back in the storage ring, and continued to probe the storage ring.
