I've Lost All My Cultivation—Senior Sisters, Please Restrain Yourselves

Bound to an odd system, I have to pretend to be a weakling with lost skills, enduring the coldness of the world and the contempt of others. But they don't know that the more I fall, the more the cold and restrained senior sister's pathological possessiveness surges. She won't let anyone truly hurt me, yet she longs to hide the helpless me in her exclusive sanctuary. Each time after being humiliated, the 'healing' becomes a suffocating entanglement and a trap of desire. I am slowly approaching the critical point that will overturn everything!
