Lin Xiaotian, a funny young man who claims to be the "No. 1 Lover in the Galaxy", accidentally activated the "Love Strategy System" from ancient civilization after being dumped for the 99th time. The system told him: If he wants to become a true interstellar lover, he must complete 99 inter-racial relationships! However, the first mission made him collapse - the target was actually the most dazzling Star Elf princess in the Federation, and his number one love rival was the Elf prince Kyle, known as "the most beautiful man in the interstellar". In order to catch up with the princess, Lin Xiaotian had to embark on a ridiculous interstellar adventure: conquering the foodie stars with earth's instant noodles, impressing the elegant singer star with square dancing, and even using mahjong culture to leverage the core secrets of the robot empire... But soon he discovered that behind this love game, there was a conspiracy network covering the entire galaxy. And every time he conquers a race, he will obtain the core technological heritage of that race. From a good-for-nothing who was disliked by the Star Spirit Princess to a legendary love saint who has attracted thousands of interstellar beauties, Lin Xiaotian will use the most sultry operations to complete the most exciting counterattack!
