From the Start, I Had Mahayana Cultivation, and Became the Sect's Patriarch

[Sect + invincible protagonist + System-based + no heroine] Please don't disturb. Zhang Shaojin endured countless hardships to cultivate to the Great Ascension realm. Thinking of his transmigrator status, he couldn't believe he hadn't gotten a golden finger. Furious, and with his lifespan nearly exhausted, he sealed himself away, determined not to come out until he got a System. Fortunately, Heaven rewards the diligent. After waiting ten thousand years, he finally got his System. [Your System only crashed for a tiny little bit, that's all.] Cursing and grumbling, Zhang Shaojin enjoyed the ten thousand years of life the System gave him and became the sect's founding patriarch. Back then: “You shameless coward! You can't beat me, so you call in some old geezer?” Zhang Shaojin yelled, tearing open a talisman and fleeing at once. Now: “You dare bully the juniors of my sect? Old geezer, are you tired of living?” With a wave of his sleeve, Zhang Shaojin wiped out his opponent's protector.
