Deep within the pitch-black Lightning Pool, at this very moment, Xiao Yan sat cross-legged in the void with his eyes closed. As his internal energy cultivation slowly circulated, a huge energy vortex formed above Xiao Yan head.
In the huge energy vortex, an extremely terrifying suction force came out. Wisps of heaven and earth energy visible to the naked eye continued to emerge from the void under this terrifying suction force, merged into the vortex, and then entered Xiao Yan's body.
As the energy of heaven and earth entered his body, the Heavenly Flames within Xiao Yan's body immediately rose up, refining that energy repeatedly until it was extremely pure. Only then did it flow along the meridians in Xiao Yan's body and merge into the qi vortex, becoming part of Xiao Yan's overall strength.
With such a long period of refining and absorption, Xiao Yan's aura also became stronger and stronger under this continuous refining and absorption. When he opened his eyes again, Xiao Yan's strength had completely reached the peak of the Three-Star Half-Emperor state, and he was only one step away from breaking through to the four-star level.
Slowly opening his eyes, Xiao Yan's dark pupils suddenly shot out two dazzling beams of fire. Accompanied by the distortion and shattering of the space in front of him, the two beams of fire, containing terrifying power, quickly disappeared into the Endless Void.
Ignoring these subtle changes, Xiao Yan Xiao Yan carefully examined his body until he was sure there were no remaining injuries. Only then did he slowly raise his head, scan the surroundings, and a satisfied look appeared on his lips.
After a moment, Xiao Yan did not rush to break through immediately. Instead, he looked to the side and stood motionless, his body like an iron tower, like the Northern King.
At this moment, the Northern King's robust body still bore the scars from his previous battle with Mu Han. Even with Xiao Yan's composure, he couldn't help but be slightly startled upon seeing the cracks on the Northern King's body.
Xiao Yan admitted that even he himself would have difficulty matching the physical strength of the Northern King. After all, the Northern King's body was that of the Dragon Clan, and his current strength had reached a terrifying level equivalent to Six-Star Half-Emperor. However, he never expected that even so, his physical body would still be broken by Mu Han. Although the damage was not great, this was the first time in all of the Northern King's past battles that this had happened.
It has to be said that Mu Han's strength is truly remarkable. As Nine-Star Half-Emperor, although he acts arrogantly and domineeringly, he has the right to be arrogant and domineering. In comparison, although Xiao Yan's overall strength is not weak, he can never compare with him.
While inwardly praising it, Xiao Yan focused his attention on the dark lightning.
Before the Northern King's strength advanced to the Half-Emperor, he really couldn't imagine that a puppet could possess the strength of Half-Emperor. After all, this kind of power was much stronger than that of many humans who actually cultivated.
However, ever since the Northern King's strength reached the level of Half-Emperor, Xiao Yan has realized that the Northern King is no ordinary puppet, and his growth limit is probably far more than that.
Although he had always wanted to try to further enhance the Northern King's strength, he had been struggling to find the opportunity. After all, ordinary lightning was useless against the Northern King, and to condense sufficiently powerful lightning, he had to rely on refining elixirs.
However, for Xiao Yan to improve the strength of the Northern King, the Pill Lightning he attracts would need to be at least of the level of Emperor Grade Pill!
However, refining Emperor Grade Pill is not so simple or easy. The Spiritual Strength and Dou Qi consumed in the process are simply too much for Xiao Yan to bear in his current state. Therefore, the terrifying Void Lightning Pool Pill Lightning has become the perfect holy land for him to improve the strength of the Northern King.
"I wonder, if the Northern King were to absorb all this lightning, to what extent would his strength advance?"
Xiao Yan slowly surveyed the Northern King, his heart filled with anticipation. After all, even someone like Mu Han was extremely wary of the lightning here, so its power was unimaginable. If the Northern King were to devour it, the effects would likely far surpass those of ordinary Pill Lightning.
Thinking of this, Xiao Yan's heart stirred slightly, and the idea of giving it a try arose in his mind.
With a thought, the Northern King seemed to receive a command, and his strong, towering figure suddenly moved, rushing towards the dark lightning.
"Bang bang bang!"
A series of explosions suddenly rang out. Xiao Yan saw the Northern King's body bouncing between numerous bolts of lightning. The terrifying energy of the dark lightning prevented him from directly absorbing it like ordinary lightning.
However, after just a few bolts of lightning merged into his body, the Northern King had already reached his limit in terms of the amount of lightning he could absorb. He probably wouldn't be able to absorb any more in the short term, and Xiao Yan could only get a vague answer.
Despite this, Xiao Yan felt no anxiety whatsoever. Cultivation was inherently difficult, especially since he was merely a puppet. To have advanced to this level so quickly already surpassed the achievements of many people's entire lives. With abundant cultivation resources at hand, why should he be in a hurry?
However, just as the Northern King charged into the myriad bolts of lightning, on Xiao Yan's shoulder, Xiao Jin looked at the flickering black lightning, and a very human-like look of desire appeared in its pair of golden eyes.
Upon seeing this, Xiao Yan couldn't help but show a hint of surprise in his eyes, but it vanished in an instant. Xiao Jin's true form was Nine Profound Golden Lightning, and absorbing lightning to enhance its strength was merely its instinct.
Previously, for Xiao Yan's safety, it was not in a hurry to devour these lightning bolts. Of course, on the other hand, it also had no intention of devouring them at the time.
After all, in its heart, no matter how great the power was, it couldn't compare to Xiao Yan in front of it. In its pearl-like eyes, Xiao Yan had long become its everything. It could do without power, but it absolutely could not lose Xiao Yan!
However, now that Xiao Yan had fully recovered, and Xiao Jin saw the myriad bolts of lightning so close at hand, the small desire that had been submerged in his heart rose up once more.
Seeing Xiao Jin's eager expression, Xiao Yan immediately smiled, glanced at the Northern King on the other side who was being bounced around like a ball amidst thousands of bolts of lightning, and said to Xiao Jin with a smile:
"Little guy, you also want to devour those lightning bolts?"
Upon hearing this, Xiao Jin, in a remarkably human-like manner, hurriedly nodded its little head repeatedly, expressing its emotions to Xiao Yan.
Xiao Yan smiled slightly, nodded, and continued:
"Go ahead, but remember, never push yourself too hard; everything should be done in moderation."
As soon as Xiao Yan finished speaking, Xiao Jin seemed not to have heard him. With a flash, her petite body appeared in the midst of the myriad lightning bolts, eagerly rushing towards those terrifying black lightning bolts.
Xiao Yan gazed at the Northern King and Xiao Jin in the sea of thunder, shrugged helplessly, and after a long while, finally exhaled deeply. A smile gradually crept onto his lips, his eyes narrowed, and he sneered in a low voice:
" Mu Han, you've really given me a great gift by forcing me into this situation! Hehe, I will definitely repay this favor in the future!"
