Cao Ya grabbed the mountain treasure, held it in his hand to examine it, and his eyes shone with divine light.

He was actually quite emotional. Back then, as a Venerable One, he tried to seize the mountain treasure, but was eliminated in the first round and left injured. More than ten years have passed in the blink of an eye, and he never expected to be able to obtain this item again.

Shi Huang, Shi Hao, and Mao Qiu, standing to the side, were also quite envious.

"This thing is profound and complex. After I consolidated my realm, I once planned to comprehend it... Alas, I am ashamed, but I almost burned myself to death in the process." Sage Honghu sighed.

The group was shocked and moved, realizing that the mountain treasure was so dangerous.

“This item is a legacy of the Supreme Hall. It would be strange if it weren’t dangerous,” Cao Ya remarked. This mountain treasure is most likely something from the Supreme Hall. Otherwise, how could an ordinary force possess such a supreme technique as the “Grass Character Sword Manual”?

"What?! The Supreme Hall?!" Everyone was surprised, and then their bodies trembled violently as they looked at the treasure in Cao Ya's hand with astonishment. This item was actually from the Supreme Hall, a legacy item?!

Legend has it that in the Supreme Hall, only one son can become the supreme ruler in each generation.

That was a powerful dojo renowned throughout the heavens, said to be the mortal enemy of the Immortal Palace.

“If it’s something from such an ancient tradition, then it makes sense,” the Sage Honghu murmured.

Even for those who have become gods, the Supreme Hall and the Immortal Palace are merely legendary existences.

"Maoqiu, when you were fighting over the mountain treasure, you didn't even know its origin?" Shi Hao looked at Maoqiu, quite surprised.

How can we determine the value of a mountain treasure if we know nothing about it?

"This thing is obviously extraordinary," Maoqiu muttered. "There are quite a few legends about this thing since ancient times."

Indeed, even though the group had not yet deciphered the secrets of that snow-white, crystalline bone, they all knew that it was an extraordinary treasure.

Cao Ya stroked the bone fragment. It didn't feel like bone; it had the warm, smooth feel of jade. It was solid and indestructible. He tried to squeeze it, but the treasure didn't budge and didn't crack at all.

Cao Ya, who was conducting the experiment, showed no emotional fluctuations, as if she had expected it all along, but the few people watching were amazed.

"What kind of creature's bones are they made from?" the Stone Emperor asked.

Given the power of the Supreme Hall, the item used to carry the transmission of knowledge must be the Supreme Bone, right?

Thinking of this, Shi Huang felt a chill run down his spine.

That's the supreme being!

Even though there are some geniuses in the Eight Domains who are hailed as young supreme beings, such as Shi Hao in front of us, and Shi Yi, who is also a double-pupiled person of the Stone Clan, those are just titles of expectation. In reality, the legendary supreme beings stand at the pinnacle of humanity, looking down on the winds and clouds of eternity, and are extremely powerful!

"How do we open it?" Shi Hao asked. If they couldn't open this thing, even if the treasure contained the inheritance of the Supreme Hall, they could only look at it with envy.

"I don't know." Sage Honghu shook his head and sighed. If he knew, he wouldn't have spent so many years trying to find the way, and even faced danger along the way, almost perishing when he attained the Divine Fire Realm.

Of course, he also understood that in the eyes of the Supreme Hall, those at the Divine Fire Realm were probably like ants.

The group circled around Shanbao, racking their brains and thinking hard, all trying to come up with a solution.

"Huh?" Suddenly, Shi Hao exclaimed in surprise, a flash of inspiration crossing his mind.

"You've got an idea?" Cao Ya asked with a smile.

"Sanren, you thought of this long ago?" Shi Hao exclaimed in surprise.

"It's pretty close." Cao Ya nodded.

"What are you talking about?" the furry ball asked, tumbling and jumping around, looking impatient and wary.

"Sanren, give it a try quickly," Shi Hao urged.

"Hmm." Cao Ya smiled, and then used six different magical techniques, all of which were applied to this bone.

Suddenly, the mountain treasure shone brightly, dazzlingly bright, and flowed with a shower of brilliant light.

"It really works!" Shi Hao exclaimed happily.

Seeing the confusion on everyone's faces, he explained:

"The mountain treasure has six sides. If it is activated by six different treasure techniques, it might be useful. In fact, it really is effective."

As he spoke, Shi Hao sighed with emotion. In a moment of inspiration, this idea arose naturally.

He wondered if the wandering man also had that same feeling of sudden inspiration.

Cao Ya, of course, didn't know how to open the treasure. He knew beforehand how to open the treasure, which is why he was so calm.

As for the six treasure techniques, Cao Ya had no shortage of them. Although he mainly focused on the Kunpeng Treasure Technique and the Thunder Spirit Treasure Technique, he couldn't have truly gained nothing from the other treasure techniques when he was a Venerable. They just couldn't compare to the first two top-tier treasure techniques.

Within his body, the Heavenly Desolation trembled, seemingly in protest: "The Kunpeng Treasure Technique is the most powerful! The Thunder Spirit Treasure Technique is not the Thunder Emperor Treasure Technique!"

Cao Ya was speechless, staring at the mountain treasure floating in the air.

The six-sided, white bone block opened with a crisp click, revealing a lid that detached itself from the bone block to show the interior.

The rosy light seemed to contain the vastness of Mount Sumeru within a mustard seed. The mountain treasure was so small, yet once opened, its interior space was incredibly spacious, like a night sky filled with twinkling stars.

Among them were several animal hides, very old, with dried bloodstains, their age unknown.

"Let me see what these are." The furry ball was excited. It reached out and grabbed two animal skins. Its body trembled suddenly, its pupils contracted, and its eyes flashed with surprise.

Shi Hao peeked over and was also incredibly excited.

"The Six Paths of Reincarnation Heavenly Technique?!" Stone Emperor exclaimed, his body trembling as if he had suffered a stroke.

"Indeed, this is the inheritance of the Supreme Hall." Sage Honghu sighed. The ancient skill "Six Paths of Reincarnation" is recorded in ancient books as being unique to the Supreme Hall. There was once a successor of the Supreme Hall who used it to dominate an era, laughing at the gods and demons of the six paths, and was invincible throughout the past and present.

It can be said that the "Six Paths of Reincarnation Heavenly Technique" is the most essential inheritance of the Supreme Hall.

Besides the Ancient Heavenly Technique, these animal hides also contain other precious techniques, such as the "Luan Bird Precious Technique" and the "Bi Fang Precious Technique."

Of these, the Six Paths of Reincarnation Heavenly Technique is naturally the most precious!

They examined the animal hides that recorded the ancient Heavenly Technique, or the animal hides that recorded the precious techniques of other races, while Cao Ya took out the last animal hide.

The animal hide was very tattered, and the inscription on it was the "Precious Technique of the Suanni," with the runes blurred and almost illegible.

"The Suanni Treasure Technique?" The Stone Emperor was surprised, sensing something was amiss.

"The Suanni Treasure Technique? Can this be a secret technique kept as a last resort?" Maoqiu wondered. The Suanni Treasure Technique was certainly not bad; it could suppress the hidden depths of many ancient divine mountains.

But this is the Supreme Hall, possessing the "Six Paths Reincarnation Heavenly Technique," a secret technique that's kept hidden deep within. It must be on par with the former, right?

In fact, the Six Paths Reincarnation Heavenly Technique can almost completely overwhelm the Suanni Treasure Technique.

Shi Hao and the Sage Honghu were also quite suspicious.

“Of course it’s not the ‘Suanni Treasure Technique’,” Cao Ya said. He extended his divine sense, but just as he touched the animal skin, he seemed to remember something and quickly stopped, signaling everyone to be ready to retreat at any time.

Although the group did not understand the reasoning, they still followed the instructions.

Then Cao Ya's divine sense penetrated deep into the tattered animal hide, sensing the special presence inside.

The next moment—

"Retreat!" Cao Ya roared, retreating rapidly. Shi Huang, Honghu Saint, Shi Hao, Mao Qiu, and the others also retreated quickly, their expressions changing drastically. However, their speed was still too slow. Cao Ya waved his hand, unleashing a surge of divine power to protect everyone.

*Sizzle!*

The sword energy suddenly burst forth, traversing heaven and earth. Amidst its brilliance, it contained the ultimate destruction, shattering cliffs, piercing the void, and rushing into the depths of the starry sky. Many stars were pulverized, like a burst of fireworks.

The "Cao Zi Jian Jue" (Sword Technique of the Grass Character) is one of the three most supreme sword techniques throughout history!
