"There are mainly two reasons why they are stopping me."
"The first reason is that everyone occupies resources; not only for survival but also for a better life."
"If everyone lived forever, occupying a massive amount of resources, life would become extremely difficult for the newborns. They would need to battle against the old monsters or beg for some resources from them. As a result, life becomes harder for each generation. They would be born not to enjoy, but to suffer. Over time, the world will become lifeless."
"The second reason is that the lifespan of every creature is limited, it can be seen as a rule. If everyone becomes immortal, it will conflict with the rule of lifespan, which would shake the foundation of the Eternity Dao Fruit."
"Although I think they are not as smart as me, these two points make sense, so I accepted them."
