[ The message he plays on Wangji, devoid of cultivation power so only another Lan trained in the language of Inquiry can understand it, is:
"The Queen distilled a tea that granted Wei Ying the ability to use and understand Inquiry with Chenqing. She may be able to do this with everyone's abilities, and may be using the spirits to spy on us.
"The spirits mentioned beheading, and a previous Queen of whom they are also afraid. They said nothing else." ]
[ And every day Wangji provides another reason for Lan Xichen to be proud of him. He plays in return:
"There is a staff who heard stories about group of people who oppose the Queen. She doesn't understand why they would oppose her, and states that the Queen is not her grandmother. She would not say anything else." ]
