Tomb Robber: the System Asked Me to Cultivate Immortality and Nourish My Lungs

In the Huojia pavilion in Changsha, I used a wheelchair to spread fish food to the koi. Ruyue brought me the decoction from the fifth year and advised me to take care of myself and recover from my illness. Just as he was about to drink, an electronic sound exploded in his head: The Taoist Cultivation System was successfully bound. I have been suffering from lung disease for five years and it is difficult to even breathe. The system wants me to cultivate immortality? Okay, I want to see what I can cultivate.
