Summoning Heroic Spirits: I Am the Only One Who Knows the Background of All Heroic Spirits

This is a world where monsters are raging and occupy 90% of the world's territorial resources! The whole people are cooped up in the tower defense city, and they can only gain powerful power to fight against monsters by summoning Heroic Spirit Cards. Every week, the Heroic Spirit system will announce the names of Heroic Spirit characters to the world. These heroic characters come from martial arts, high martial arts, cultivating immortals, gods and demons, and mythological planes. Anyone who composes the background story of the Heroic Spirit character and gets the Heroic Spirit's approval can obtain cards with different star levels based on the compatibility of the story. From 1 star to 10 stars, cards with different star levels have different enhanced attributes! Lin Yi discovered that he was the only one in the world who knew the background stories of these heroic figures! While others could only draw 1 to 3 star cards with rubbish attributes by guessing, Lin Yi was filled with glowing full-star cards! The star-filled Dugu Sword Demon Heroic Spirit Card from the martial arts plane. The full-star Kurosaki Ichigo and Li Chungang Heroic Spirit Card from the high martial plane. The Heroic Spirit Card of the Man-starred Saiyan Emperor Araten from the plane of gods and demons. And Hongjun from the mythical plane... This novel and its characters are purely fictitious.
