"The last era?"

Jiang Ming was stunned. He looked at the huge skeleton in front of him in surprise. It was like a mountain.

"These demonic beasts are extremely terrifying. When they mature, they can contend with mighty cultivators. The best among them are even more terrifying. The strongest among them can almost arm-wrestle with Saints," the black sword said slowly. "However, this race is similar to the demonic beasts at the beginning of many eras. Their bodies are too huge, and they need to absorb a huge amount of vitality to survive. It's very common in the early stages of the world's formation. However, in the middle of the last era, when the entire world entered the 'living' stage, these giant beasts became very rare after they lost their living environment. Then, they were completely extinct and could not survive. If such a ferocious creature exists forever, then no one else can prosper. The world is born and subsequently destroyed. There are laws. How many living beings can transcend? After millions of years, everyone I knew has passed away. In the end, I am the only one drifting alone in the river of time."

Jiang Ming glanced at it from the corner of his eyes. He was holding himself back from saying anything. When the time came, he would let it know what immortality truly was.

"However, why would there be such a huge skeleton in the burial ground of a Saint?" the black sword muttered. The scene before it was something that even an old fox like him could not understand. "Everything here evolved from the cultivation fruits of a Saint. However, this kind of beast was born at the beginning of the world. Its origins are mysterious. The only possibility is that the Saint brought this skeleton here before he died."

The more the black sword thought about it, the more it could not figure it out. In the end, it could only give up speculating.

Jiang Ming walked slowly to the skeleton and tried to touch it.

However, he had just touched it when a crack suddenly appeared on the bone, which was still sparkling and translucent like jade. After which, it shattered like porcelain. The entire skeleton soon shattered into shards so fine that they looked like ashes.

"It's good-looking but useless!"

Jiang Ming was almost buried in it. He quickly coughed violently and retreated. It seemed that this skeleton had been here for too long. No matter how strong it was when it was alive, it could not withstand the erosion of time.

Jiang Ming released a breeze made out of spiritual energy to sweep away the dust in front of him before walking forward.

The bones that seemed extraordinary before had lost all their luster.

"Looks like there's no use for it anymore," Jiang Ming shook his head with some regret. The bones of ordinary demonic beasts could be used to refine weapons. However, there was nothing he could do with these bones.

"Hmm? What is this?" Just as Jiang Ming was about to give up, he suddenly found something shiny in the pile of bones.

He pushed aside a pile of broken bones and picked up a crystal ball the size of an egg. It was reflecting a faint light and had a bumpy surface, like amber.

"It's the origin bone. It's a treasure formed from the essence of their bones and blood after they die! It's very useful for cultivators who follow the path of body tempering," the black sword explained. "It can even be used to refine powerful bone puppets."

"This is the origin bone?" Jiang Ming was pleasantly surprised. He had read about it before. This was the first time that he'd come across one.

It was said that origin bones were very rare in the world, and every one of them could be sold for an extremely high price. However, they were next to impossible to find.

According to the ancient records, the origin bone was born from the fusion of the underground spirit vein and the bones of powerful creatures. However, no one would have thought that these peerless beasts were the source of the origin bones.

Jiang Ming looked at the sparkling light in the pile of bones again, and his face was filled with joy.

With a flick of his finger, a storm made from spiritual energy immediately swept out and enveloped the small mountain of broken bones.

The origin bone was extremely hard. However, these broken bones that had lost their spirituality were no different from dirt. In just a moment, the pile of broken bones was ground into dust and swept away by Jiang Ming. In the end, only some sparkling and warm origin bones were left on the ground quietly.

Jiang Ming put all the origin bones into his storage ring. Including the first one, there were more than thirty of them. Even the three grotto-heavens of the Feather Kingdom combined might not have so many.

Jiang Ming was satisfied and continued to walk forward. After crossing a few mountains and walking for more than ten miles, he was stunned.

"Why is there another one?"

Jiang Ming looked ahead. Another huge skeleton stood at the end of his line of sight. It was even bigger than the previous skeleton, and its appearance was different. It only had four legs and one head. It seemed to be the skeleton of another demonic beast.
