The Leader Seems to Be Invincible

Mo Jiuxiao traveled through time and became the leader of Xiaoyao Sect. I really wanted to be a free man, but it turned out that this sect was in trouble. Every now and then, powerful enemies come to your doorstep. His disciples are all weird. There is a male disciple who took the Jade Girl Pill and became a peerless beauty. There are disciples who can go back in time for a short period of time. Alas, I can load the files and do it all over again. Mo Jiuxiao is so envious. There are disciples who return to their youth and live a new life. However, the fact of rebirth is not that simple, but they can also be used as prophets. There is also the lurking prodigy of the Vampire Clan. His disguise is excellent and his mission is very successful, but this is not the case after meeting Mo Jiuxiao. … When you are such a broken leader, you really don't have to worry about everything and your family can be wiped out at any time. Fortunately, he has an invincible system of 'respecting the old and bullying the young'. Facing opponents younger than him, he can directly receive the system's invincible combat power. But when facing an older person, he has to lower himself to two realms, and he must not accidentally kill the old man, otherwise he will be severely punished or even die! Therefore, no matter how many talented disciples you have, it doesn't matter where you come from or what you want to do. Anyone who is younger than him is his good disciple and cannot escape from his grasp. As for those ancestors who are older than him, Mo Jiuxiao doesn't have to be afraid. Are these talented disciples like him just raised to eat for free?
