National Tower Defense: Are the Undead Weak? Have You Ever Seen a Natural Disaster?

Shen Fei traveled through the world of national tower defense and awakened the undead soldiers. Everyone says that the undead are weak and cannot die quickly in the later stages. But for the first time he drew ten consecutive cards for free, he drew the special card Undead Peasant. I thought it was a useless card, but in the secret realm of tower defense, the land planted by an undead farmer can restore people's blood, turning it into a spring water making machine! Are the undead weak? Have you ever seen a natural disaster?
