Entering the Immortal Sect at the Age of 100, All I Want Is to Seek Immortality

[100-Year-old female cultivator + no CP + hidden strength + growth battle] Just after his 100th birthday party, Xie Sangyu awakened the ultimate mutated ice spirit root in a mountain disaster. But her meridians were withered and her life was about to expire, so the sect was only willing to give her one year to prove herself. After being assigned to take care of a remote medicine garden, the old medicine bag that had been with her for eighty years unexpectedly awakened, allowing dead elixirs to be reborn and ordinary elixirs to be upgraded. From then on, she hid the medicinal herbs during the day, repaired the withered veins and secretly broke through at night. The world said that one should be buried at the age of 100, but she decided to start from the age of 100 and embark on a path to immortality.
