There is a lot of space underground, and after Li San has consolidated his realm a little, he began to grope in this huge underground cave.

He kept groping his way in the direction of the current.

Take a hundred steps forward. He was shocked to find that the waterway was lined with the skulls of the white forest. The skulls looked a little shiny, and the bones were very fine. Presumably, these people must have been great and strong people in their lives.

for they are among these skulls. A number of glittering white jade-like skulls were found. That's definitely what was left over after the death of the super powerhouse.

"Damn, how can there be so many dead people here?" Li San couldn't help but be scared when he saw these skulls, and he acted even more cautiously.

"Twitter......"

Suddenly, a dense stream of black bats flew towards him.

"Humph!"

Li San's body suddenly emitted a dark cyan True Yuan force, his hands waved violently, countless palm shadows appeared around his body, and those bats were wiped out before they could get close at all. Li San, who has entered the foundation building period, has been able to use some spell attacks.

As time passed, after walking for about ten minutes, some bright lights gradually appeared in front of him, and finally, the entire passage suddenly opened up, and a huge stone gate appeared in front of Li San's eyes. There were three big characters on the stone door, but Li San didn't know those three words.

"It's strange, I want to see what is behind this stone gate!" Li San finished speaking, and came to the front of the stone gate.

The stone gate is not very heavy, and with Li San's current strength, he can easily open the division gate.

Behind the stone gate was a large space, and Li San found that there were countless corpses lying in the middle of the room, probably because they were too old, and these corpses had turned into white bones and were scattered all over the ground.

On the bluestone walls around the cave, every ten meters are inlaid with an extremely rare round night pearl, scattering a soft milky white light, illuminating the entire cave slightly.

"This is the Pearl of the Night, but baby!" Looking at the beads around him that exuded misty fluorescence, Li San's heart was excited.

Some objects on the ground reflected fluorescent glows, changing and blurring in mid-air, and the colors were colorful, which made Li San a little dizzy.

Li San squinted his eyes slightly, looked at it intently, and was surprised to find that there were fairy treasures everywhere, including crystal clear crystal pots, fragrant folding fans, silkworm gloves inlaid with gold and silver, and many flying swords. Seeing these things, Li San was already able to affirm that this place was definitely a place left over from the heyday of cultivating immortals.

Li San casually picked up two swords that exuded a cold glow, but when he injected his internal strength into the sword body, all those swords broke inch by inch.

"Damn, it's a waste product!" Li San couldn't help but curse in his heart.

"Why did so many supreme masters suddenly die in this hall?" Li San looked at the environment around him and fell into deep thought.

After checking, Li San found that these people were all super masters in their lives, and the bones of those dead were kept very intact, and it could be inferred that these people were directly scattered by others and died.

"Forget it, no matter how they died!Let's see if there are any treasures elsewhere!" Li San walked to the center of this space, in the center of this stone cave, there was an ancient pagoda, this ancient pagoda was all made of mysterious metal, and it was rusty on it, with a total of nine floors.

The gate of the tower is a huge stone gate with a large black stone door carved into it. Around this giant tower, there are dense skeletons, these bones are looking up at the giant tower in front of them, and from that action, they feel a deep despair.

"Well, damn, the highlight is here!" Li San looked at the giant tower, looking extremely excited.

The entire giant tower is 100 meters high, and the door on the first floor of the giant tower is the same as the previous door, which is hidden. Li San exerted all his strength to feed, and the huge door was slowly pushed open.

"Boom!"

After half a ring, Li San finally pushed the bronze giant door open a crack.

"Damn, how can this door be so heavy?" he grumbled, and immediately dodged in.

When Li San entered the Bronze Giant Tower, he couldn't help but gasp, because the Bronze Giant Tower was full of Sen Sen's white bones, and there were some huge beast bones among them. There were broken weapons everywhere.

"Damn, have I entered hell?" Li San walked around the bronze giant tower for a long time with a feeling of sorrow, and found no treasures at all, but found an ancient book made of unknown materials on the body of a skeleton.

"What bullshit? Why is there no word?" Li San flipped through the black book, but he didn't find a word on it at all! But Li San didn't think it was a garbage book, not because of anything else, just because the book could be preserved in the endless years of washing, which was enough to prove its extraordinary.

Li San was holding the black ancient book and thinking, "Could this thing be like the legendary immortal magic weapon to be dripping blood to recognize the master?"

Thinking of this, in the end, Li San, who had always been afraid of pain, still frowned and bit his fingertips, squeezing out a drop of bright red blood on his fingertips, and when Li San's blood dripped on the black ancient book, a golden rune in his blood drilled into the black ancient book. Of course, it is impossible for these Li San to discover. He stared at the black ancient book in his hand with wide eyes, and saw that the black ancient book was like a dry sponge, absorbing all his blood.

After absorbing Li San's blood, the black ancient book finally showed a trace of change, a trace of misty light emanated on the ancient book, and ancient characters slowly appeared on the pages of the black ancient book.

"Hmm, why is this book getting hot?" Li San looked at the ancient books in his hand with an incredulous expression, and the ancient books had changed dramatically at this time. I saw that the black ancient book slowly softened, and finally turned into a puddle of black liquid.

Although everything in front of him was beyond the scope of Li San's cognition, for Li San, who believed that there were really immortals and ghosts, he still suppressed the fear in his heart and quietly watched the changes in the black ancient book on his palm.

The temperature of the liquid transformed by the black ancient book became higher and higher, and finally the liquid penetrated into Li San's palm.

"Sneer~~"

Those black liquids turned into a fiery stream of energy in Li San's body, and then drilled into his mind.

Li San felt that there was a huge amount of information in his mind out of thin air, and Li San spent half an hour sorting out and digesting that information, and the preliminary conclusion was that the name of this ancient book was called "Heavenly Pattern Secret Dictionary".

The Celestial Pattern Secret Book is not a martial arts secret book, but a kind of exercise equivalent to the left path of the side door.

Although he was a little disappointed in his heart, Li San still did not give up and continued to hunt for treasures.

In the bronze giant tower on the first floor, Li San didn't find anything that could catch his eye, and the things in it had lost their due value due to too many years.

Inside the second layer, there were still skeletons, but in the bronze giant tower on the second floor, Li San found that there were many fewer bones here than those on the first layer, and in the bronze giant tower on the second floor, Li San did not find anything useful.

"Damn, I thought there was any treasure, at least a black book could be found on the first layer, and ......there was not even a single bird feather here," Li San, who couldn't find the baby, began to scold.

When the chattering Li San entered the third layer of the bronze tower, he found that in the space of the third layer of the giant tower, although those people were dead and the corpses had long since decayed, those bones were still very hard, not like the first and second layers, Li San pushed a little harder, and those bones would be shattered.

On the third layer, Li San still didn't find any treasures......

On the fourth floor, Li San found some blood stains on the ground or wall of the bronze tower, although those blood stains were dry, they were preserved in the endless years, and those corpses were wrapped in a layer of yellow wax-like skin, as if the dead years and months had not been long in life, and the clothes on those people could be well preserved.

"Hehe~~ There's a baby now!" Li San was very happy, because he had already seen a dried corpse with a black ring on its hand.
