Lu Li had been cultivating divine energy for many years. The divine energy in his pellet was surging and it had changed several times. Now, it had turned into a light yellow color.
In a normal situation, such as releasing divine energy to attack, the divine energy would not be used up even after more than a decade.
Now, when he was learning the Bone Refinement Skill, the divine energy would be used up in a couple of days.
It was not hard to imagine how amazing this ancient skill was.
Lu Li understood the principle of the Bone Refinement Skill. It was to use divine energy to melt the bones and remove all the impurities in the bones so that the bones would be less dense and sturdier.
At the same time, divine energy was converted from Xuan Energy in heaven and earth. Nourished by Xuan Energy, the bones would be changed as well. They would become unbreakable and full of strength.
"Let's try it ~"
Lu Li had a lot of pellets with him. He didn't sell the top level ones that could last him for months.
He mobilized divine energy to use the Bone Refinement Skill and began to refine his bones. While he was doing so, his bones glowed.
Then, there seemed to be some suction cups in his bones. The divine energy Lu Li mobilized surged into his bones like a river.
"Hiss, hiss …"
Lu Li mobilized a lot of divine energy but in the time for a few breaths, the divine energy was absorbed. Lu Li had to keep on mobilizing divine energy.
His bones were like a whirlpool at the bottom of the sea. All the divine energy he mobilized was sucked in.
"Buzzing ~"
Lu Li took out pellets from his ring and swallowed five at once. Those pellets were meant to assist in the cultivation of divine energy.
As soon as the pellet entered his body, a surge of strong efficacy spread out. Lu Li used his cultivation method. Spiritual energy in heaven and earth surged into his body like tidewater. His meridians were filled with divine energy that was converted into it.
However, as soon as Lu Li used the Bone Refinement Skill, the divine energy was absorbed by his bones.
His bones were like a bottomless pit. No matter how much divine energy Lu Li cultivated or mobilized, the divine energy would be sucked in instantly.
"Go on!"
Lu Li mobilized divine energy from the pellets. He only needed to keep some of it. He planned to use up the rest. He could just spend more time on cultivation in the future.
Divine energy surged out from the pellets and then was absorbed by his bones.
After cultivating for three days, Lu Li could clearly feel that his bones had changed. They had become stronger, and they were crystal clear, like pieces of Artifact.
Lu Li remembered the hand bone of a powerful warrior that the Young Master picked up in the first two levels.
Although that expert had inscribed divine runes on his hand bones, it should have the same effect as his bone refining technique, although it was a different approach.
The hand bone was also sparkling and translucent, emitting a dazzling divine light like a secret treasure.
"Continue!"
Lu Li was excited that the bone refinement skill was working. He mobilized more divine energy.
Thirteen days after Young Master Qin and the others left, Lu Li stopped. Over half of the divine energy in his pellet had been consumed. He had to keep the rest for himself.
For more than ten days, there was no movement at the top of the mountain. From time to time, he would use the Trace of the Great Dao to sense it, but he didn't find anyone hiding at the top of the mountain.
He still did not act. Instead, he waited for Blood Fairy to refine the small seal.
Blood Fairy had said that Xiao Ying would need a month. More than ten days had passed, so it should be soon.
"Hum ~"
Lu Li took out bottles of pellets and began to cultivate divine energy.
He had over a thousand pellets, all of which he gained from killing people over the years. They were all high level pellets of the Second Plane.
Lu Li would take the pellets, cultivate divine energy, and then use the ancient skill to refine his bones. The cycle repeated.
Every time, Lu Li would take three pellets. He would only take more when the effect of the pellets was gone.
Time flew by. Soon, a month had passed. Lu Li had consumed over six hundred pellets. He did not even know how much divine energy he had cultivated. Anyway, it was all absorbed by his bones.
His bones were changing. There was a hint of yellow glow in them. Lu Li was beginning to evolve to the second level.
That being said, Lu Li was frustrated that his bones had only progressed a little after absorbing so much divine energy and using so many pellets. It seemed that to reach the second level, he would need at least tens of thousands of bottles of pellets. This was the second level.
How many would he need to reach the third level? How many pellets would he need to reach the fourth level?
Lu Li could not imagine. Maybe … at the end, using regular divine energy would be pointless. In the end, he would have to resort to elixirs.
"Crackle, crackle ~"
Lu Li stopped cultivating. He stood up and stretched his bones. Every movement made his bones creak. He waved his hand. He felt his hands were filled with strength. He felt he could kill a Three-star Beast of Primordial Chaos with one punch.
"Whoosh ~"
His body floated up, and he began to run in circles around the stone mountain. As he ran, he clearly felt different. All the bones in his body were filled with great power, and his speed increased by another 20%.
He believed that by using the Unfettered Steps, his speed would be similar to a warrior at the peak of the third tribulation.
"This is good!"
Lu Li was satisfied after running around for a while. Though he had consumed most of his divine energy and so many pellets, his physical strength had improved by 20%, which made him happy.
The price was worth it. This ancient secret technique was extremely powerful, and it was extremely useful for refining one's body.
It was a pity that the skill was incomplete. It lacked the skills of skin and blood refinement. Otherwise, if he could learn all of them, it would be much easier for him to build a supreme body.
"Let's go up!"
Lu Li turned around and dashed upward. This time, it was easier for him to reach the one thousand feet mark. He kept on going. At the two thousand feet mark, he could no longer move.
He stood there and used the trace of Dao to sense the situation up there. He did not sense any signs of life. The people up there must have been teleported away.
"Whoosh!"
Lu Li rushed down and sat down to consume the pellets while Blood Fairy took control of the seal.
After six days, Blood Fairy finally said, "Master, I have solved the runes on the Seal of the King of Dust. I will give you the way to control the runes. You can control the Seal of the King of Dust."
"Why is it called the Seal of the King of Dust?"
Lu Li was surprised. Blood Fairy explained, "This is the information left in the seal. It was made by a man called the King of Dust. It is a high quality artifact with Divine Patterns."
"Oh, I see!"
Lu Li was relieved. Blood Fairy reached out her tentacle and sent some information to Lu Li's soul. Lu Li digested the information and took out the Seal of the King of Dust. He poured divine energy into the Seal of the King of Dust.
Based on the information from Blood Fairy, Lu Li activated some runes, and then the entire Seal of the King of Dust. In the end, he could control the seal.
"Buzzing ~"
After a moment, the Seal of the King of Dust glowed. The runes on the seal glowed, and some runes appeared. Gradually, Lu Li established a spiritual connection with the Seal of the King of Dust.
"Go!"
Lu Li flew the Seal of the King of Dust up. Surges of primitive, vast, and horrifying energy came out from the Seal of the King of Dust. The seal flew around in the air as if it was his own arm. After a while, Lu Li grabbed the Seal of the King of Dust in his hand.
