You Were Followed?... Fighting The Gu Worm!

Without hesitation, Ko took the pill from his spatial ring and placed it on the table. He had recognized the pill's similarity to one described in an ancient scroll he'd encountered, which emboldened him to make this wager. Otherwise, he knew many pills bore similar appearances.

Upon seeing the pill, the worm demon was stunned. It was remarkably similar to the Nine Serenities Pill, but how could it be in the lower realm? Puzzled, the worm demon dared not approach the pill; something felt extremely off about the pill to it.

Seeing this, Ko's expression subtly flickered before quickly returning to normal.

"Master, you should know that taking the Nine Serenities Pill will restore you to your peak strength. Then we can conquer this world and head to the immortal world."

A flash of ambition gleamed in Ko's eyes.
