I'm Really an Assistant

[Invincible + SSS level talent + system + academy + all races in the world + childhood sweethearts] Originally I was just an ordinary high school student, but one night suddenly a light flew into the center of my eyebrows, Ding! Congratulations on awakening the Supreme Growth System. As long as you complete the tasks, you will receive generous rewards. …Congratulations on completing the mission and obtaining the God of Creation talent, mastering life and destruction. …Congratulations on completing the mission and obtaining the exclusive artifact Life Scepter… …Congratulations on completing the task and getting… Alien invasion. You and your teammates will protect Blue Star to the death and fight towards the starry sky to make all races surrender. End? It's just a joke! Since I stand up, I will save this rotten world! All survivors, hold on to your weapons and listen to my orders. Whether they are aliens or in desperate situations, they will all be crushed! The introduction is too weak, so please move on to the main text. This is the first work written by the author. I hope to get encouragement and support from my family.
