Bottle after bottle of essence and blood was poured, and the Heavenly Demon Bone Umbrella really seemed like a bottomless pit, indiscriminately and greedily swallowing the essence and blood.
It took more than ten minutes before he finally poured all his essence and blood onto the Heavenly Demon Bone Umbrella.
As expected, with the substantial replenishment of essence and blood, the Heavenly Demon Bone Umbrella underwent another transformation, as if returning to its original simplicity, with the blood vessel-like patterns on the umbrella disappearing.
Not only that, even the originally terrifying aura on the umbrella had vanished, making it seem, at this moment, like an ordinary object.
If someone unaware saw it, they would hardly notice anything unusual about this umbrella, and would never suspect the power it contained, capable of withstanding the attacks of a Saint Level expert.
