Tan Xiu Teng was close to becoming a peerless top advanced Supreme God after all. He could naturally understand Duan Ling Tian's thoughts. With their cultivation bases, they had to consider their actions all the time to avoid forming the Heart Devil, which would affect their chances of survival during the Heavenly Tribulation.
Tan Xiu Teng knew that if he was not ordered by Meng Yu Zheng and sincerely harbored the intention to kill Duan Ling Tian, it was likely that Duan Ling Tian would kill him. It would be fine if Duan Ling Tian was open-minded. If not, Duan Ling Tian would have to kill him so that he would not form the Heart Devil that would affect his Heavenly Tribulation.
'Fortunately, I was only ordered to kill him,' Tan Xiu Teng thought to himself as he sighed in relief.
Then, he shook his head when he thought about Meng Yu Zheng. He knew that Meng Yu Zheng was going to die soon, after all.
