The Most Powerful Weapon System

The system comes with the magical power of great anger. Doesn't it mean that the angrier I get, the more powerful it becomes? "Why did you cheat me by only giving me a long sword with white equipment? What I want is the Infinity Blade, the sword's critical strike!" "Host, you don't have enough experience." "Cerebral palsy system! You're so mad at me!" "Hey, congratulations to the host, the anger value is full! You have obtained the legendary divine armor, the Four Swords of Killing Immortals. I wish you can block the killing god!"
