The book that I recommend to you is the Celestial Support Ring. It's a sci-fi novel that travels through time and space. It's somewhat similar to the Exquisite Ring. The protagonist uses a magical ring, through time travel, space jump, and other abilities, he obtains many fortuitous encounters and becomes an omnipotent combat genius. The story was fast paced and the plot was full of ups and downs. It was very suitable for readers who liked science fiction. This book is free, so you can read the whole story without any worries. I hope you like my recommendation. Muah ~
