“Bring Nan Xianxian here.” “Your Highness, Lady Nan went out to walk her cat...” “Bring her back.” “Bring Nan Xianxian here.” “Your Highness, Lady Nan climbed over the wall and ran off...” “Bring her back.” Nan Xianxian transmigrated to ancient times and became a low-ranking concubine in the manor of a sickly regent.

The System says, “Anything can be exchanged for your life.”
