Although Duan Ling Tian had only met Zhao Lu, he felt comfortable around Zhao Lu. Moreover, Zhen Ping Fan had asked Zhao Lu to look after him, which showed Zhen Ping Fan's trust in Zhao Lu.
Hence, coupled with his own judgment, Duan Ling Tian trusted Zhao Lu's warning about Lan Xi Lin being vengeful and petty.

Thinking about Lan Xi Lin, a thought suddenly appeared in his mind. He quickly sent a message to Ye Bei Yuan to remind Ye Bei Yuan to be careful of Lan Xi Lin even though he thought it was unlikely that Lan Xi Lin would act against Ye Bei Yuan and his disciple due to Zhen Ping Fan's involvement. Nonetheless, it was always good to be cautious.
