The ingenious plan of the ball of liquid metal

Aside from the marvelous ability to prolong one's life, the living spring had another property... it was very tasty.

Song Shuhang believed that something had gone wrong when the living spring in his Heart Aperture took shape.

Why were the seeds of the Virtuous Golden Lotus able to prolong one's life and grant an extraordinary skill to whomever ate them, while the nucleus in his Heart Aperture—which had transformed into a living spring after absorbing a large quantity of energy of the Netherworld—only turned out to be tasty?

Song Shuhang didn't flip the table only because the living spring in his Heart Aperture had, at the very least, the decency of not spurting out of his body like those lotus seeds.

Anyway... the fact that he now possessed this 'living spring' capable of prolonging one's life was still something worth celebrating.
