Clara, a woman who previously regained the ability to stand, suddenly finds her legs unresponsive again. Another woman at the scene accuses Lowel, a man who treated Clara, of using deceptive tricks. Lowel explains that Clara stood earlier only because he temporarily infused her legs with his own internal energy, which has now dissipated. He states she must cultivate her own energy through training, a process he admits took him a year. Enraged, Clara issues an ultimatum: she gives him only three days to fully cure her legs, threatening severe physical harm if he fails. Lowel, now trapped by a signed contract and a seemingly impossible deadline, is left to face the consequences.
