The suction force continued to increase, seemingly without end. Even Gu Yi was somewhat surprised by the situation, as he hadn't anticipated it to escalate to this extent.
As the world's energy continuously merged, Gu Yi was forced to increase the infusion of his spirit power. This, in turn, caused his internal reserves to deplete rapidly. Although his spirit power was far greater than that of other Spirit Masters of the same level, he still had a long way to go to reach the level of a Titled Douluo.
His spirit power was gradually being emptied out, and the vortex that had initially been in his hand had long since floated into the air, continuing to absorb both his spirit power and the world's energy. It's hard to imagine how catastrophic of an explosion this uncontrolled entity could cause. However, such a scenario was practically impossible.
Even now, Gu Yi's spiritual power remained abundant, allowing him to suppress the unstable vortex. Despite this, the rapid consumption of his spirit power left him looking pale.
As his spirit power drained away, the vortex in the air still demanded more, becoming increasingly unstable with the cessation of his input. Although Gu Yi could temporarily stabilize it with his spiritual power, this was only a stopgap measure. If no further spirit power was injected, he would have no choice but to disperse the vortex with his Primal Energy Domain to avoid a massive explosion.
Gu Yi remained calm. Although his internal spirit power was depleted, it didn't mean he had no other resources. He still possessed the external spirit bone obtained from the Ten-Thousand-Year Sky-Swallowing Toad, which contained a large amount of spirit power.
When he first acquired this external spirit bone, its storage capacity was not large, roughly equivalent to a quarter of his dantian's capacity. However, as his cultivation progressed, the spirit bone had also evolved, expanding from a quarter to nearly two dantian's worth of spirit power. If even these reserves were insufficient to form a spirit core, Gu Yi would accept the outcome.
Once he drew upon the spirit power stored in the spirit bone, his pale complexion began to recover, and his body filled with soul power once again.
The infusion of spirit power stabilized the output, and the vortex, infused with both spirit power and the world's energy, began rotating, purging impurities while compressing. The liquid spirit power gradually coalesced into a solid state, forming silver-white solidified spirit power that grew slowly in size.
Each person's spirit core is unique, and Gu Yi's solidified spirit power, formed through the cultivation of the "Zhoutian Liuhe Jing" could be called an elemental spirit core.
The massive input of spirit power also meant more and more of the world's energy was being absorbed. The energy of heaven and earth from all directions gathered above the Ice and Fire Yin Yang Well, connecting with the vortex floating in the air inside the room, continuously feeding energy into it.
The solidified spirit power continued to grow.
"What on earth is Gu Yi doing in there?" Dugu Bo, resisting the suction force, was shocked to see the massive concentration of energy. Even in his long life, he had never seen such a phenomenon.
Meanwhile, the Blue Silver King took this opportunity to absorb the world's energy fervently, recognizing the moment as a rare opportunity. Over countless centuries, no place had ever gathered such an abundant concentration of the world's energy.
The disturbances in the Sunset Forest attracted the attention of both spirit masters and spirit beasts, all drawn to the site by the enormous gathering of world energy. Such a concentration could only signify the appearance of some heavenly treasure. Large numbers of spirit masters and spirit beasts began converging on the location.
Unaware of the commotion outside, Gu Yi continued to pour his spirit power into the vortex. The small room was now filled with brilliant light, and Gu Yi's martial spirit glowed intensely. The powerful fluctuations generated by the vortex began tearing open silver-white cracks in the surrounding space, unable to withstand the immense energy.
As the spirit power output continued, the vortex's fluctuations reached an unprecedented peak, with the rotational speed almost beyond Gu Yi's spiritual control. But it was finally nearing its end. Gu Yi could feel that the vortex in the air was reaching its limit. As he observed that only a quarter of his spirit power remained, he breathed a slight sigh of relief.
Outside the hut, Dugu Bo had already retreated from the doorway, feeling the immense pressure. If he hadn't restored his vitality a few months ago and significantly increased his strength, he would have struggled to control his soul power.
Suddenly, an unexpected change occurred.
The usually calm Ice and Fire Yin Yang Well suddenly emitted two dazzling rays of light—one red, one blue. Even with his sharp eyesight, Dugu Bo could barely trace their paths, reacting too slowly to prevent them from shooting into the small room.
Gu Yi noticed the change as well.
"What is this?" Gu Yi was momentarily stunned as he watched the two rays of red and blue light merge into the vortex.
This unexpected development caught him off guard. The vortex, which had already reached its limit, underwent a dramatic transformation as the two rays of light merged into it, instantly breaking through its previous constraints.
The world's energy flooded into the vortex with even greater intensity. Seeing this, Gu Yi felt a moment of despair. He could only increase the output of his spirit power while also intensifying his spiritual control to stabilize the vortex.
At this point, Gu Yi had no time to ponder the origin of the two rays of light. The vortex's rotation speed increased rapidly, pushing his spiritual power to its limits. He had not yet reached the point where he could expend it without restraint. Unable to maintain control, he could only push forward to the end.
As he stabilized the vortex, Gu Yi also began to compress the two invading rays of light, steeling his resolve. Since they had intruded, he would take them in fully. The two rays of light contained immense energy, and Gu Yi could even sense a trace of divine power within them.
His face turned pale again as his spirit power neared depletion. The vortex was also reaching its peak.
Now, it was a matter of seeing who would last longer.
Outside, the miasma was already surrounded by a multitude of spirit beasts, but no spirit masters were in sight. Wealth and opportunity are important, but life is even more so. No spirit master would willingly put themselves in danger.
The Sunset Forest wasn't vast, and while it didn't have hundred-thousand-year-old spirit beasts, there were still beasts that had lived for tens of thousands of years. These beasts all eyed the miasma warily but dared not approach.
Eventually, Gu Yi's spirit power ran out. The vortex became extremely unstable as the world's energy continued to pour in.
A look of unwillingness appeared on Gu Yi's face. He hadn't expected to fail at the final step.
"Human, if you agree to our terms, we can help you stabilize this uncontrollable vortex." A voice filled with majesty and dominance echoed in Gu Yi's mind. The previously unstable vortex suddenly calmed down.
"Who's there?" Gu Yi looked up but saw no one. However, his spiritual power detected a trace.
"Who are you?" Gu Yi asked, his gaze fixed on the red light, sensing that the voice had come from it.
"I am the Fire Dragon King, one of the Ten Dragon Kings."
