My Lady, Please Hold Back. Stop Helping Me Cultivate Immortality

"An'er, you promised back then that you'd stay with me for the rest of your life."

"But how was I supposed to know, Madam, that you're a Mahayana cultivator? Your lifetime lasts for thousands of years!"

"I'll help you cultivate immortality. You just need to lie flat. Leave everything else to me."
