Yang Lie, who didn't quite understand what had happened, didn't delve too deeply into it.
Following Yu Xiaogang's instructions, he went to a device shaped like a furnace.
He placed the piece of crimson blood amber that Yu Xiaogang intended to use into the furnace, then circulated his spirit power and activated Martial Soul Possession.
In an instant, a fan surrounded by crimson flames appeared in Yang Lie's hand.
This was Yang Lie's Spirit, the Crimson Fire Fan—a Spirit that could release blazing fire with every wave of the fan.
As the Crimson Fire Fan appeared, six spirit rings materialized around Yang Lie.
Immediately after, his first spirit ring lit up. Yang Lie waved the Crimson Fire Fan, and roaring flames surged into the furnace like ocean waves.
The crimson blood amber, held in mid-air by the device inside the furnace, was scorched by the intense fire. It soon turned red all over and showed signs of softening.
Seeing this from outside the furnace, Yang Lie immediately activated his Second Spirit Skill, making the flames inside the furnace even more intense.
In this manner, with Yang Lie's continuous input of flames, the crimson blood amber inside the furnace began to melt and burn.
Eventually, the crimson blood amber turned into wisps of smoke, which drifted toward the inner part of the secret chamber through a pre-prepared fixed channel in the furnace.
Meanwhile, Yu Xiaogang, who had long been prepared inside the secret chamber, watched the approaching smoke. He circulated the spirit power in his body and began to absorb it.
The smoke didn't have the choking smell Yu Xiaogang had expected; instead, a refreshing fragrance filled his nostrils.
The distinct scent of trees and plants filled Yu Xiaogang's body, making him feel a spontaneous sense of physical and mental comfort.
The most wonderful thing was that inhaling smoke burned by fire should have felt scorching hot.
But the smoke Yu Xiaogang inhaled now only felt refreshing.
Yu Xiaogang only lingered on the scent of the smoke for a moment before quickly immersing himself in the process of refining the medicinal power of the crimson blood amber.
As the majestic medicinal power circulated through his body and he converted it into his own strength, Yu Xiaogang once again felt the extraordinary nature of these two pieces of crimson blood amber.
With just a bit of conversion, Yu Xiaogang could clearly feel that his total spirit power, physical fitness, and even mental strength had increased to some extent.
With this sensation of rapidly growing stronger, Yu Xiaogang looked forward to seeing what level he could reach once he had completely refined the medicinal power of the crimson blood amber.
As time passed, Yang Lie, outside the secret chamber, had finished burning the crimson blood amber completely.
Feeling that more than half of the spirit power in his body had been consumed, Yang Lie took a breath.
"I didn't expect such a small piece of amber to be so troublesome to burn. What kind of treasure is this exactly?"
It was no wonder Yang Lie was so curious; as a fire-attribute Spirit Emperor, burning just a single piece of amber had actually drained most of his spirit power.
One should know that with the same amount of spirit power released as flames, Yang Lie could have set the entire Heaven Dou City ablaze.
"Thank you for your hard work. Come and rest for a bit. Once Xiaogang finishes absorbing the medicinal power, you'll burn the other one in a while."
Yu Yuanzhen walked forward with a smile and patted Yang Lie on the shoulder, looking as if he thought very highly of him.
In an instant, Yang Lie felt his previous fatigue vanish completely.
The Sect Master told me 'good job' and even patted my shoulder...
Does this mean I've caught the Sect Master's eye?
At the thought of having caught the Sect Master's eye and rising through the Ranks of the Sect in the future, Yang Lie suddenly didn't feel tired at all.
"Don't worry, Sect Master, I'm not tired at all! I'll definitely burn the Young Sect Master's other piece of amber to completion!"
Hearing Yang Lie's words and seeing his excited eyes, Yu Yuanzhen nodded in satisfaction.
"If only those old foxes in the Sect were this easy to handle,"
Yu Yuanzhen thought to himself with a touch of regret.
Afterward, everyone waited outside for Yu Xiaogang to finish absorbing the medicinal power of the crimson blood amber.
In this way, half a day quickly passed.
During this time, the people waiting outside several times considered entering the secret chamber to see the specific situation.
However, in the end, they all held back.
It wasn't until evening that, with a creak, the door to the secret chamber opened, and a dazed Yu Xiaogang walked out.
"Xiaogang, how did it go?"
Seeing Yu Xiaogang's dazed expression, Yu Yuanzhen thought something had gone wrong and hurried forward.
Upon hearing Yu Yuanzhen's voice, the dazed Yu Xiaogang snapped back to his senses.
"Father, I... I've reached Rank 40."
Yu Xiaogang said in a light, airy voice.
"What Rank?"
Hearing Yu Xiaogang's words, Yu Yuanzhen's voice was also filled with disbelief.
"Rank 40."
Yu Xiaogang repeated. After refining a portion of the crimson blood amber's medicinal power, his Rank had reached this level.
At that moment, he thought he had misperceived it. He checked over a dozen times before confirming that he had indeed broken through to Rank 40.
"Wait a minute, what Rank were you before you went in?"
Yu Yuanzhen held his head, looking as if he couldn't process this.
"He was Rank 35 before going in."
Before Yu Xiaogang could speak, the Grand Elder nearby spoke up.
He clearly remembered Yu Xiaogang's spirit power Rank; it was definitely Rank 35 before he entered.
"So, that piece of crimson blood amber directly raised you by five Ranks?"
Yu Yuanzhen's eyes widened.
In just half a day, his spirit power had surged by five Ranks!
This was more Ranks than he himself had gained from absorbing that 80,000-year torso bone and 30,000-year skull bone.
But on second thought, he was gaining three Ranks as a Titled Douluo, while his son was gaining five Ranks as a Spirit Elder—the difference in scale was immense.
But the problem was, he had used two Spirit Bones, especially one being an 80,000-year torso bone.
"I didn't expect you to reach Rank 40 just like that. I thought you'd gain one or two Ranks at most this time."
Taking a deep breath, Yu Yuanzhen said.
Both he and the Grand Elder had previously consumed immortal grade herbs, and the Ranks they gained were roughly similar.
He had broken through from 96 to 97, and the Grand Elder from 88 to 90.
He gained one Rank, and the Grand Elder gained two.
As for the Grand Elder's two Ranks, the jump from 88 to 89 was just a matter of needing an opportunity.
In the language of novels, the Grand Elder was at the Peak of Rank 88.
So in reality, the Grand Elder's Breakthrough could also be seen as gaining one Rank.
Both of them had only gained one Rank, which led Yu Yuanzhen to believe that the primary role of an immortal grade herb was to improve talent and evolve a Spirit.
The increase in spirit power wasn't supposed to be that much.
Yet for his son, it was directly five Ranks.
And this spirit power increase was, after all, just a byproduct of absorbing an immortal grade herb.
The true function of an immortal grade herb still lay in improving talent, evolving the Spirit, and raising one's potential ceiling.
Being able to improve his talent while also raising his spirit power Rank was a very celebratory event for Yu Xiaogang.
After all, for a Spirit Master, the time saved by gaining five Ranks was measured in years.
Especially since Yu Xiaogang was currently still in the golden age for a Spirit Master to Cultivate.
At this stage, five Ranks of spirit power were no less beneficial to Yu Xiaogang's future than absorbing a 10,000-year Spirit Bone.
