Sword Saint's One-Hit Kill: The 'Strongest' Sequence?

In a modern city, Su Xing transmigrated after waking up. Initially wanting to start a business and take off, he unexpectedly awakened the Sword Saint System. Not wanting to waste the system, Su Xing became a sword instructor. He thought life would just go on peacefully, until he discovered that this world actually had supernatural powers, and his younger brother was a naturally gifted Sequencer. A door to an unseen supernatural world opened before him. Sequencers, the Spirit Cult, Him, Secret Realms, Sequence Beasts—one trouble after another followed. Su Yu worriedly said, "Bro, it's okay if you don't have the talent to become a Sequencer. I'll definitely work hard to get stronger and protect you!" Su Xing smiled faintly: "There's no need for that. I'll just add points to my system." Slash—One sword to split the sky. Thrust—Lock onto causality. Breathing rhythm—The Way of the Sword Saint. Just like that, going to work, teaching students, adding points. Unknowingly, Su Xing found that he had become invincible. Su Xing: "Sorry, under my sword, whether it's some Sequence or Spirit Cult or whatever else, it's all just flashy nonsense."
