Immortality, I Use Time Silk to Extend the Ultimate State

[No system + Slightly relaxed + Gou Liu] Be careful when entering the trap! Su Wuxia traveled through time and was reborn in the world of cultivation. He had an immortal body and was born with a piece of flawless jade. He is immortal and has unlimited lifespan. The flawless jade adds a strand of light every year he lives. He discovered that the function of light threads was to prolong a certain state of his being. For example, an epiphany, which is rare for others, feels like a huge opportunity once a stick of incense is touched. But Su Wuxia's epiphany was extremely lasting. For example, when refining alchemy, others marveled that their alchemy was like divine help, and it was as difficult as climbing to the sky to maintain it. But Su Wuxia's divine help lasted ridiculously long. For example, when refining a weapon, others can feel the breath of the material for an instant, but it is fleeting. But Su Wuxia's feelings lasted forever. Who is the peak of the Taoist cultivator? Once you see it, you will become empty.
