Transmigrated to Ancient Times: The Path to Immortality Begins with My Master's Wife

【Invincible + Ruthless and Decisive + No Needless Suffering】 My name is Hu Lai, and I transmigrated into a world where martial arts reach the divine. With nowhere else to turn, I got lucky and became the most despised, most useless disciple at a martial arts school. But an Invincible System tome lay in my mind. It was my transmigrator's gift. My master was beaten half to death, and my senior brothers all ran off with their belongings. Only I, the transmigrator, had nowhere to go, so I had no choice but to stay and watch over the place. Then, in the middle of the night, my master's wife knocked on my door! Starting from a rundown martial arts school, I claim a mountain as my own and hack my way through countless worlds.
