Card Maker? No, Call Me the Greatest Card Merchant

Mandate Battle Cards. Manifestations of the laws of Heaven. They possess all kinds of wondrous, mysterious powers. They are divided into Monster Cards, Skill Cards, Equipment Cards, Item Cards, Material Cards, Consumable Cards, and more... Only those who awaken the power of cards can wield Mandate Battle Cards. In this card-based world, young adults must leave home and live independently after their coming-of-age ceremony. To avoid starving to death on the street, Ling Yuan, the unremarkable fifth son of a card-making family, chose to become a card merchant. "I want a Mythic Monster Card with infinite attack. You can make that happen?" "I want a Skill Card that can instantly kill a Demon King. You have three days!" "I want an Equipment Card that grants immunity to all abnormal status effects. I'll be waiting for good news." Ling Yuan: "No problem. Leave it to me!" No matter what kind of customer he faces, Ling Yuan can always deliver the most satisfying creation. But his greatest strength isn't card-making. It's card battles. Ling Yuan: "Summon one hundred Monster Cards!" "Activate one hundred Skill Cards!" "Use one hundred Equipment Cards!" Are you sure you want to rob me? How can Ling Yuan do all this? Because he obtained the Supreme Card God System. [Ding! You have acquired the System skill: System Points.] Whenever someone uses a card made by the Host, the Host receives points equal in value to the card power consumed. There is also a chance that the points earned will be multiplied. The multiplier cannot exceed the System's level. [Ding! You have received 23 points.] [Ding! You have achieved the highest critical hit. The current maximum System level is LV10.] [Ding! You have received 23 x 10 = 230 points.]
