Counterattack System appeared when I'm already At The Mahayana Realm - Chapter 53 - Past and Present Sword

As a creation-type devil fruit, the Superman Barrier Fruit is not too much to use it to open Susanoo, right? Katakuri’s glutinous fruit can have countless fists, can’t my barrier fruit do it?

The biscuit fruit of the cracker can have a biscuit army, but can’t I have a barrier fruit? Brother Ming’s thread fruit can have a shadow riding thread clone, but can’t my barrier fruit? What, even mr3’s wax fruit has so many wax figure clones, and candle robot armor?

No, I have to refer to it, and I have to play better! My barrier fruit should be greener than blue and better than blue! My creativity is beyond your imagination! !

- Description from novelbuddy

Florentia was reincarnated as the illegitimate child of the richest family in the empire.

Born of a great family, world shaking genius.

Qin Tian accidentally transmigrated into a sickly body, a body with broken Dantian that was unable to practice Qigong, in another world. Fortunately, God had mercy on him by giving him a level up system. Useless? That was him in the past. Not worrying about practicing Qigong, he was now able to kill Monsters to level up. Easy! Level up when killing Monsters; level up when killing people. An unbeatable sovereign of the clan in the eyes of other people, but in his eyes, he is a glittering big BOSS.
