After hundreds of years of cultivating immortality, I am about to die before Golden Finger comes

Jiang Chengxuan accidentally traveled to the world of immortality and accidentally obtained the inheritance of immortality.
However, the qualifications are really low, and after a hundred years of hard training, he still cannot advance to the realm of foundation building.
Just when he was disheartened and silently came to a mortal city, ready to end his life, the golden finger finally arrived.
It is detected that the host has achieved the achievement of cultivating immortals for a hundred years, and is hereby rewarded with a life-extension fruit. Taking it can increase the life span by one year.
The next achievement mission is now released.
Ask the host to complete the level a hundred times. After completing the level, you will achieve the achievement of 100 times and get a chance to successfully complete the level.
Ding!
Ask the host to complete a hundred times of spell practice, and upon completion, you will receive a jade talisman of perfect spell inheritance.
Ask the host to complete a hundred times of movement achievements. Completion can improve the root bone.
Ask the host to complete the talisman-making achievement a hundred times...
Ask the host to complete the achievement of enlightenment a hundred times...
Ask the host to complete the achievement of alchemy a hundred times...
Ask the host to complete the hundred poisoning achievements...
Please host...
Unknowingly, when Jiang Chengxuan heard the system prompt again, he was shocked to be told that there is no more achievement for you to complete, because your existence itself is already an achievement that can never be surpassed.
