Cannon Fodder Upgrade Rules

On the day Lin Wan was abandoned by his master, he received the last mission: to go to the main city and find the missing senior brother. This task usually goes nowhere. She accepted it calmly. Anyway, her life was no different from that of grass on the roadside. But she didn't expect to see the "Alchemy Pond" with a sea of ​​blood surging under the splendid main city. Unexpectedly, the blind harpist who was rescued by chance was the former immortal king who fell into heaven; The injured little fox picked up on the roadside is the missing crown prince of Qingqiu; And that mysterious man who always drank with her across the wall late at night, laughing and talking about subverting the three realms... It was Master who sent her into this devil's cave with his own hands. "You see," Master held the chess piece and chuckled, "The brightest light can only be found in the darkest darkness in the world." "Wanwan, you are my most perfect work." —— When the calamity of destruction came, all the sentient beings who had abandoned her like worn-out shoes knelt down and begged. She lowered her eyes and looked at the sword in her hand. Countless faces showing love and hate were reflected on the blade. This time, she has the final say whether to save or not.
