Otto: No? I Use the Thousand Blades of the Demonic Knife to Kill Monsters?

I never dreamed in my life that something so outrageous would happen. Just this morning I traveled to the Ultraman world, but compared to the situation below, it was nothing to mention. Because I actually bound the system! Also unlocked the Demonic Knife Thousand Blades! "A thousand blades of the magic sword beat monsters? I'm not the author. Are your brains okay?" In this Ultraman world, use the magic sword Thousand Blades to defeat monsters? Oh, can it get bigger? That's okay. Belial: Look at my ultimate combat instrument... Why do you have such a wide range of weapons? Mo Qi: Of course it's because I have a lot of energy!
