Super Invincible Defense

Wang Lu, a 20-year-old sophomore, encountered an unknown creature "invading" the campus during class. For the reason of saving a troubled female classmate, he "unfortunately" became the target of thirty "friendly" classmates. I thought I would be safe if I escaped into the office with the security door locked, but I found that my situation became even worse. But there is no way out, he actually developed his own decisive defense ability, and from then on he soared into the sky like a dragon out of the sea! With absolute defense, all attacks are in vain! With defense in hand, I have the world!
