My Class of Martial Gods

Class Five of Mingde High's first year is the 'Class of Hell-raisers.' Its students are failures at Martial Arts. They've driven away teachers, and no one dares to take the job. Substitute teacher Silas's Teacher System activates, and he volunteers to take over. When Vicious Beasts sweep across the nation, Silas gives the command, and these 'misfits' transform into top-tier Martial Gods, holding up the sky for everyone!
