The Tianhe Great Ancestor always saw Lu Xuan as a thorn in his side. The Xu family also said that this Great Ancestor had always been a terrible character.
Now that he had figured out that Lu Xuan stood in his way of getting what he wanted, he would not let Lu Xuan go like this!
If that's the case, then Lu Xuan might as well have just gotten rid of this Tianhe Great Ancestor.
If Lu Xuan had not found out, then nothing would have happened. However, now that he already knew, he definitely would not let this matter go. None of this would've happened had Lu Xuan never found out.
He could not just wait until Tianhe Great Ancestor was ready to deal with him.
Xu Hongyi quickly reminded Lu Xuan, "Senior Lu, it's been quite a while since this Tianhe Great Ancestor has been in the Divine Transformation Realm. I'm afraid it won't be easy to deal with him!"
