The protagonist became a baby after transmigrating to another world. Did he have a younger sister who had reached the invincible realm in the other world and was only in her teens?

Hehe, it seems that you are very interested in the theme of the male protagonist traveling through the other world, invincible, ruthless, and without a female protagonist! Then, I recommend two good novels to you: "From University Student Overlord to Chief Academician" and "Invincible Upgrade System." The main character of "From University Student King to Chief Academician" was a master of mathematics who became an inventor of super technology after obtaining the Academic Genius System, while the main character of "Invincible Upgrade System" was a male protagonist with an invincible upgrade system. He had the ability to learn in seconds and win the heart of a beauty. I hope you like my recommendation. Muah ~

😋I recommend the following novel to you: "Reborn in the Original Otherworld". The protagonist found that he had inexplicably transmigrated to a primitive society in another world, and elves, dragons, and so on were just a group of ignorant creatures. The main character cultivated Taiji and had amazing talent and strength. However, he was not a likable person and did not have a halo. He did not like to be entangled with others and only pursued his own path. He did not care about anything else. I hope you like this fairy's recommendation. Muah ~😗

I'm not sure about Tang Yin's cultivation realm in the other world because I'm a fan of online literature.
