I Committed Suicide by Triggering Thunder at the Beginning. I Am Really Not a Lunatic!

[Aura recovery + system + rebirth + power awakening + dark invasion] In Blue Star 3096, the Dark Portal came in full force, and countless dark creatures and weirdness swept across the entire planet. All the awakened people in the world united and resisted desperately for only a week, which also meant that the fate of mankind was completely towards destruction. When he woke up, Tokikawa found that he was reborn in high school and had awakened the main god training system. Unwilling to repeat the same mistakes, Tokikawa is determined to regain the courage to face the darkness. The thunder is drawn from the sky, the thunder rushes, the thunder strikes wildly, and the thunder is fierce. Under the dark night, the roar of "Crush the darkness with thunder!" Resounded across the sky!
