Nangong Xu never went to the castle on the mountain; every time something happened, he would have a video call with Xiao Zexin.
Xiao Zexin found that this person was unusually guarded.
Ruan Tianling also inquired about some of Nangong Xu's preferences and habits from Qi Ruigang.
As a result, Qi Ruigang didn't know Nangong Xu's weaknesses either; in his eyes, Nangong Xu never left others an opportunity to strike.
He had always lived in Nangong Castle, where almost everyone was on his side.
Therefore, getting to him was even more difficult.
However, they didn't have much time to delay. They had to quickly deal with Nangong Xu, then take Nangong Ruyue away to save Jian Yufei's life.
Xiao Zexin had no choice but to come clean with Nangong Ruyue.
He wrote a note explaining how Jian Yufei's illness came about, how it could be cured, and all their plans.
Then he slipped the note to her while treating her illness.
