Traveling Through Another World and Being Exiled, Relying on the Spiritual Spring to Make a Comeback

In her previous life, Cheng Yan relied on her natural power and awakened superpowers to survive in the apocalypse, but in the end she fell into a swarm of zombies and was surrounded and suppressed and lost her life. When she opened her eyes again, she was dressed as a substitute for Chi'er, who was married to the down-and-out third prince. Fortunately, the spiritual spring in her body also followed! The down-and-out prince is seriously ill and is about to die. What should I do if my mother-in-law goes blind from crying? It doesn't matter, just drink some spiritual spring water. What should they do if the eldest prince who has ascended the throne still refuses to let them go? It doesn't matter, then come back and push him down!
