After Transmigrating into a Book with My Twin Brother

I transmigrate into a book alongside my twin brother and find ourselves in a story about wealthy families and fake heiresses. Gu Jiangwan says, "No need to panic. Let me have some fun first." Gu Mingxi: "My massive business empire... It came along with me, too." Gu Jiangwan: "So, are we still going to acknowledge our birth families?"

Jiang Sinian/Jiang Wang: "I'll protect you, even if I have to hold the whole world hostage."
