The Struggle for Supremacy at the End of the Sui

Since the author wrote that the protagonist traveled through magical worlds, he should be able to use magic in this late Sui Dynasty setting. If he can't, what's the point of writing about him being reborn in many worlds? What's the use? How is he any different from other transmigrators vying for supremacy?

You've already done it all to A-Lan and you still won't marry her? Author, are you really that much of a scumbag?

The beginning seems alright, but could it be poisonous later on?

I suddenly remembered that this book I rented before might be on Qidian. I checked and found that it didn't have many good reviews. So I'm leaving a comment. This is a masterpiece in the late Sui Dynasty. The characters are vivid and well-developed. However, it is a bit depressing in the first and middle parts. You can check it out yourself.

War, war, war! The protagonist has maximum combat strength and maximum strategy!

Isn't this too casual? The plot is too perfunctory.
