The World Has Changed a Lot Since Shrinking

[Group pet article + no cp + male protagonist + slow-burning plot flow] Le (lè) Qing was washed up in the sea and found that she had shrunk and looked like she was three years old. When he was wondering whether he had traveled through time or was reborn, a woman on the seawall flew down and picked him up. Um? Fly down? This is time travel, right? Later it was discovered that he did not travel through time, but simply shrank to three years old. I also learned that this world had been invaded by some death game, and the chosen people had awakened their powers. Obviously it was only a week between when he jumped into the sea and when he was salvaged, but the world has changed? Post-it note: Healing group pet article, true healing + true group pet. It's a light suspense story about Jack Suven. The protagonist is covered, so it's not an upgraded novel. A group pet redemption article that cannot be read with the brain. What are the tags for modern imagination, modern romance, and fantasy romance? Our protagonist doesn't have a CP, okay? How many of the three romance tags do the protagonists need to talk about?
