As the elixir took shape, Liou Yuan sensed it and murmured the name of the elixir, "Foundation Establishment Elixir!"
Liou Yuan did not immediately take out the Foundation Establishment Elixir. Instead, he focused his mind and carefully placed the Thunderstruck Horn within the sword energy seal of Celestial Calculation Imprisoning the Profound Nether.
The exploding liquid from the Star Evil was its essence blood, which nurtured the spiritual object of the Thunderstruck Horn.
According to what the Fixed Star Compass said, the Thunderstruck Horn needs to absorb this essence blood to transform into a unique object.
As Thunderstruck Horn entered the sword energy seal, it didn't require Liou Yuan to feed it proactively; the Thunderstruck Horn's body automatically erupted in azure lightning.
Like claws, the lightning extended outward, pulling in the scattered liquid, dragging it all into the body of the Thunderstruck Horn.
