The Sixth Senior Brother, always regarded as a soft touch within the immortal sect, is in fact a deeply hidden and highly accomplished cultivator. The Junior Sister arrives carrying a system, intending to test his true identity and seek cultivation opportunities—only to be outmaneuvered at every turn. A storybook foretells that great tribulation is approaching the sect; no one knows that the Sixth Senior Brother is actually a woman, who disguised herself as a man to avoid disaster and has long been secretly laying plans to break the deadlock. She calmly advises the other to stop scheming against her cultivation foundation, and instead look to their own safety and figure out how to survive the heavenly tribulation.
