Chen Mobai originally had a Xu Tian Wu Jin Dan, but he gave it to his father, Chen Xinglan, because he had repeatedly failed to achieve Foundation Establishment and had damaged his vital essence and lifespan. Ordinary Life-replenishing Elixirs were of no use.
Thus, in the Immortal Gate, dying peacefully of old age is considered a happy event.
Many cultivators who exert themselves too much in attempting Foundation Establishment don't even live to a hundred years old, like Chen Mobai's grandparents.
After Tang Lu's cremation, Chen Mobai personally placed his ashes into the cemetery.
"Son, your father-in-law was always proud of you, he definitely wouldn't want to see you upset," Chen Xinglan said to comfort Chen Mobai, who forced a very strained smile on his face, standing in front of the grave, watching the cemetery workers engrave Tang Lu's name and other details on the tombstone.
