Can one use social media names in a story?

The world is under invasion by creatures from another world. Martial arts became the most important skill in this world, and all cultivators strived to improve their skills. Chen Yiming transmigrated to this world with a special ability - the Martial Arts Talent System. The system allowed him to use Skill Points to enhance his talents infinitely. What if he was born with a physique that was not suitable for cultivating martial arts? He could slowly train in the mountains while waiting for his Skill Points to accumulate. When they reached a certain amount, he could use them to enhance his talent and automatically acquire the physique needed for cultivation. What if he did not have the complete volume of the martial arts technique he practiced? It wasn’t a problem. With sufficient enhancement to his talents using Skill Points, he could automatically deduce the missing parts in the book. With the Martial Arts Talent System, he could defeat everyone who got in his way. He could easily climb the ranks in the martial arts world - becoming the top disciple, the top cultivator, then the grandmaster.

Lin Qi transmigrates to a world of immortals. In this world, there are sword immortals who can behead a person from a thousand miles away, peerless great demons who burn mountains and boil the seas, and ancient gods and devils who can divine the heavenly secrets. As a disciple in charge of miscellaneous chores in the Skysword Sect, Lin Qi doesn't have any cultivation talent. A hundred years had passed in a flash, and seeing that he has nothing to do with such a great world, Lin Qi is incomparably depressed. Just as he is about to die of old age, he suddenly awakens a cultivation system. Unlocked One-Click Cultivation System: Limitless cultivation speed boost, one major realm per second! Unlocked One-Click Technique Practicing System: Cultivation technique instantly maxed out. Cultivate 10,000 techniques at the same time! Unlocked One-Click Clone System: 100% of the actual body's strength. Can self-destruct, can teleport, can fuse! As a result, Lin Qi begins to cultivate again with his hundred-year-old body, becoming invincible under the heavens.
