When I Draw Cards to Cultivate Immortality with Krypton Gold, I Can Only Draw R Cards?

[Card cultivation + non-chief + picking up leaks + R card counterattack + multiple female protagonists] The year I traveled to the world of immortality, I awakened. When others awakened SR and SSR, they were rushed by the elders to accept them as disciples. I awakened ten cards - eight R2s, one R1, and one "Thank you for your patronage". The whole world of immortal cultivators is laughing: Are those who have awakened with the R card worthy of cultivating immortals? I also want to ask: Why? Until I discovered something - I could "see" the light inside the cards. R2 is dark gray, R1 is pure white, SR2 is light green, SR1 is verdant, SSR2 is light gold, SSR1 is golden, UR2 is lavender, and UR1 is purple. Level eight cards are invisible to me. That day, I dug out a rotten card with half of it burned out in the city's garbage dump - it was glowing lavender. UR2 residual card. Priceless treasure. I exchanged my last three spiritual stones for this pile of "junk", and the stall owner laughed at me for being such a fool. They didn't know that from that day on I started researching those R cards that no one wanted. Three R2s are stacked together to create the A-level skill [Sword and Fire Starts a Prairie Fire]. Seven R cards are arranged and combined to reproduce the SR-level effect [Earth Escape and Invisibility]. Nine R cards are stacked in a specific order to pry open a crack in the rules of heaven. Later, I used nine R2 and three breaths to defeat the genius who was holding a UR fragment. He knelt on the ground and asked me: "Where did you buy those nine R2 cards?" I smiled: "Garbage pile. Three spiritual stones per pound." Now the entire world of immortality is asking: When did the price of R card increase? I pointed to the "R Card Combinations Collection" I just finished writing: "Since I discovered this."
