Beagan apparently survived after his heart was cut out. Why did he die on the spot after seeing the old woman selling vegetables?

It's a pity that God played tricks on people. After Bi Gan dug their hearts, he happened to meet an old woman selling vegetables at the intersection, who was transformed by da ji. Da ji deliberately said that the food he sold was unintentional, which attracted Bi Gan's attention. But because Jiang Ziya told Bigan not to talk to people, Bigan went on. Therefore, da ji was unwilling and cried out to be unintentional; ? How can a person live without a heart? In the end, da ji's words defeated Bigan, who soliloquized da ji's words and fell to the ground and died.
