Lin Yun had long sensed that some changes had taken place, but he never expected them to be so drastic.
Originally, he was somewhat worried that he wouldn't be able to defeat Dongfang Ming, as she was a god, after all, and deserved some respect.
Although after two days of cultivation with Dongfang Hongyue, his strength had increased significantly, he still didn't think he could slay a Divine Spirit.
The reason Dongfang Yao was at a disadvantage against him was purely because Lin Yun understood him too well, and his own flame quality was superior to Dongfang Yao's Sun True Fire. Coupled with the Cheating Heaven Step Technique and Fire Spirit Avatar, he was able to pull off a sneak attack.
Without one of his trump cards, he wouldn't have been successful.
And if he hadn't previously invaded Dongfang Yao's body, he wouldn't have been able to inflict any damage.
