A Fusion Skill That Could Threaten Deities

The greater the compatibility between both parties in a Martial Soul Fusion Skill, the more powerful it became. Chen An was doing everything possible to increase the compatibility between the Ice Dragon King and the Fire Dragon King, ideally allowing them to reach one hundred percent.

As the Ice Dragon King's and Fire Dragon King's energies fused further, the ice-fire energy emitted increasingly terrifying fluctuations. It was extremely volatile, looking as though it could lose control and explode at any moment, yet it somehow remained stable, maintaining a balanced equilibrium amid the chaos.

The Ice-Fire Energy Sphere had expanded to over ten meters in diameter. The Ice Dragon King and Fire Dragon King had long since flown into the air, unwilling to let the energy sphere touch the ground and be affected by it. The energy sphere was unaffected, but the ground was not. It had already sunk deeply and continued to collapse outward.

Chen An, Gu Yue Na, and the others had no choice but to move farther away. They could no longer withstand the powerful energy fluctuations produced by the Ice Dragon King's and Fire Dragon King's merging energies. Even Chen An, whose current strength was nearing the ultimate level, found it difficult to endure them, showing just how fierce those fluctuations were.

Within the sphere of intertwined ice and fire energy, enormous ice-fire dragons twisted and danced, their impassioned roars echoing one after another.

Both the Ice Dragon King and Fire Dragon King were sweating. As more and more energy fused, supporting it became increasingly difficult for them. They both felt that they had reached their limits and could barely maintain it any longer.

At this point, their soul compatibility had also reached its peak. Chen An could no longer further connect the origins of their souls.
