The Frost Bone Dragon lay weakly on the ground.
The blood-colored Soul Fire in its eye sockets was dim and lifeless, akin to a flickering candle in the wind, ready to be extinguished at any moment.
Although the Undead Race can absorb the deathly aura of the world to slowly repair their injuries.
However, this repair process often requires a long time.
With the Frost Bone Dragon's injuries so severe.
It would take at least a hundred years to recover to its prime.
But at the moment when Lu Yuan's soul strength increased.
The blood-colored Soul Fire in its eye sockets surged, once again bursting with new vitality!
At that moment.
All the Catastrophe Servants, no matter where they were or what they were doing, felt the change in their power.
They all turned their heads toward the direction where Lu Yuan was, their eyes filled with unprecedented respect and fervor!
And Lu Yuan seized the moment, diving into the ocean of Alchemy.
