Who isn't afraid of death? Everyone is afraid of dying, so it's normal for people to worry about it. You can't say someone is wrong for feeling this way.
"For saving lives."
The Great Grandpa didn't say much, he just uttered these words.
"Our Bai Family Village must do whatever we can, we cannot ignore the suffering and let others die without help. We must save everyone who needs help.
I know you might be scared, that's why we are at the entrance of the village. You don't have to go outside, if you don't move about, you won't be in danger. All matters are also being handled by the village head.
I'm just at the entrance. From now on, Bai Zhi and I won't step into the village. Rest assured."
Bai Zhi's house doesn't require entering the village, and if medicinal herbs are needed, they don't need to enter the village.
This is the best approach. It also gives people a chance.
