He did not expect his enemy, Lugh, to save him. However, Duo Hong also knew that Lugh wanted him to report his brother's matter when he returned. Then, his brother, Duo Long's, leadership would be weakened in the family, if Duo Hong could survive, Duo Hong would definitely do so.
Usually, Duo Hong was quite afraid of Duo Long, but now that Duo Long was going to kill Duo Hong, Duo Hong could not tolerate it. His brother was going to kill him, so Duo Hong could not tolerate it any longer. Therefore, after Duo Hong got out, he would definitely report his brother.
Duo Hong did not know how to face Lugh. Lugh had saved him, but Lugh had saved him for his own benefit.
Lugh was now Duo Hong's benefactor.
So Duo Hong didn't know what to do with Lugh. However, Duo Hong wasn't an ingrate. Lugh had saved him, so Duo Hong would help Lugh.
