Back in Ancient Times, I Had No Wife: I Relied on My Sister-In-Law to Support Me!

(I won't be paralyzed forever. In Chapter 17, the hero goes to the ground, and in Chapter 21, he completely recovers!) Lai Da Lang traveled to a small mountain village in troubled times; she had no father, no mother, no wife, and she was paralyzed on the bed! Fortunately, he has a stunningly beautiful sister-in-law who never leaves him, taking care of him, eating, drinking and having sex. As a time traveler, Lao Dalang was unwilling to sink, forcibly awakened the system, activated the golden finger, and embarked on a life of cheating! A few years later, Lao Dalang stood in front of the huge imperial map of the empire, holding her hand, and said to the rich and beautiful people in the harem: "My biggest wish was just to walk as normal. How could I accidentally unify the world?"
