After some contemplation, Su Yu fixed his gaze on the Supreme Growing Soil. Under normal circumstances, spiritual creatures of the universe would grow until a certain age, then shrivel, wither away, and eventually die.
The lifespan of the Heavenly Orchid Silver Bamboo was around a thousand years. Influences from the growing environment, such as insufficient Spiritual Energy, the absorption of excessive impurities, or destruction by various demonic beasts or humans all led to an incomplete growing environment.
Consequently, the plant generally died around the age of a thousand years, when its lifespan would naturally have exceeded a thousand years if not affected by such negative growing environment factors as were just listed above.
