The Magic of Time Travel Changes the World

The predecessors of time travel have invented glass, soap, fireworks, papermaking, printing, membership systems, gourmet food, etc. You can't even think of it. There is nothing they can't invent. This is simply a rhythm that will kill the newcomers. Lin Ling traveled to such a world. Other people who traveled through time came quietly. She not only brought herself with her, but also brought a passerby with her. Sparks and lightning along the way, Purple Qi came from the east ninety thousand miles across the sky with great fanfare and fell into the eighty thousand mountains outside Yujing City. Then, she discovered that there was a system in passerby A, and she and this unlucky passerby actually had a life-and-death relationship... A ghost... In short, this is a story about a male protagonist who was dragged into the wrong world by an unlucky girl and magically changed the normal ancient world along the way! (Updated by chance→_→)
