The key

"Why? Do you know where the book is?"

"Yes. It's in my library."

"What? In your library?"

"We need to go there now." Lei said.

Noticing something strange in Longwei's expression, Yun Qi ran up to him and grabbed his hand.

"You have a very smart child. But this is not surprising." Lei coldly but still with the warmth in his voice said.

Lifting Yun Qi up, Longwei said, "Xing Fu said that this book should not fall into the wrong hands. So let's go."

Walking down the stone stairs, Longwei moved as quietly as possible so as not to attract Yue Liang's attention. But once on the first floor, Yue Liang nevertheless appeared in front of them in his night robe and with a mug of hot tea. Without recognizing him, Longwei had to approach him and after making sure it was really him, he said, "Yue Liang, I have decided to return to my clan. It will be better this way. And besides, I cannot burden you with my presence."
