When the modern campus goddess Su Tang woke up, she traveled to a different world and became a beautiful stand-in for the mysterious lord in the escape team. I thought I was getting a survival and farming script, but I accidentally got involved in a lot of suspense in the lord's mansion. In order to save her life, she had to use her genius to deal with various characters while using modern knowledge to work hard to farm and build infrastructure. The cold-faced lord seemed to be looking at another person through her, the maid beside her behaved strangely, and disturbing whispers came from the depths of the wasteland... When she gradually touched the core secret of the world, she realized that her time travel was no accident. Should I settle down and be the shadow of others, or should I carve out my own way of life? Su Tang decided that even if he is a substitute, he must prosper and live a glorious life!
