The strongest empress is on campus

Description

She was the number one empress in the world of immortality, but she didn't expect to be poisoned to death on her wedding night. Once she was reborn as a high school student on Earth, she had an unloving father and a vicious stepmother, and anyone would step on her just because she was the idiot girl of the Gu family.
When the idiot becomes a genius and shines again, practicing immortality with his left hand and medical skills with the right, you all kneel down! The most sinister man smiled fondly and said, "Woman, when we've had enough fun, let's go home."
