Start with Slave Owners

I woke up and traveled through time, and was discovered by a senior time traveler. Fortunately, she was a good person. I originally thought that as a slave owner, I only need to learn from Lincoln in another world. As long as I don't go to the theater or ride in an open carriage, I should be able to live my life with a conscience. But the dead original owner didn't give him this chance. He was messing around in his mind, trying to stuff the contaminated memory into his mind. It's okay now. He has to face all kinds of strange knowledge and mysterious sacrificial rituals. Of course, magic still has to be learned. If you traveled through time, you wouldn't learn magic?
