My Sect Is Stronger Than It Looks by Darren Yu

Once, he stood at the very top of a sacred land. Then the elders turned against him. Stripped of his position and driven from the sect he once ruled, he left with nothing but the clothes on his back. That was when the system awakened. Its mission was simple: Build a sect. Recruit disciples. Develop its territory. And turn an unknown mountain into the greatest cultivation force the world had ever seen. From that day forward, everything changed. Ten disciples broke through at once. Then a hundred. Then ten thousand. Every achievement brought new rewards—rare treasures, powerful formations, countless draws, and even cultivation strong enough to shake the entire continent. The sect grew. Its fields produced heavenly herbs. Its disciples became monsters among geniuses. Even the creatures wandering around the mountain were no longer ordinary. Years later, an invading Demon Lord finally arrived at the sect gates. Then he saw the yellow dog guarding the entrance. He stared at it. The dog stared back. An Emperor Realm aura quietly filled the air. The Demon Lord's face twitched. “You call this a declining sect?” “Your damn watchdog is stronger than half the rulers on the continent!”
