In the past, Lu Ming had never understood who the 'he' that the Jade Emperor was referring to when he said 'you are ultimately not him'.
If what Yan Heng said was true, that 'he' was referring to Ye Qing.
The relationship between Emperor Yao and Ye Qing was extraordinary.
Lu Ming guessed that the Jade Emperor had also guessed that Lu Ming was the reincarnation of Ye Qing and thus summoned him to meet him. In the end, when he saw the pool of blood in Lu Ming's body, he finally understood that Lu Ming was not the reincarnation of Ye Qing, and thus said those words.
Lu Ming did not suspect that Yan Heng was lying.
That was because the pool of blood seemed to acknowledge Yan Heng and even took the initiative to help him remove the curse.
Yan Heng had said that he and Ye Qing were best friends, so it should be true.
And that pool of blood was left behind by Ye Qing. Ye Qing's blood had sensed Yan Heng and took the initiative to help. All of this made sense.
