Rag knew that if he were to fight against Lugh, he would not be a match for Lugh at all. He already knew about Lugh's close combat abilities. Previously, he was severely injured by Lugh. How could he not know Lugh's close combat abilities? Lugh's strength and speed were above his.
Moreover, he had the support of the bone saber in his hands. His bow and arrows were completely unable to contend against Lugh's bone saber. Well, as long as he slashed at his arrow, the arrow would basically break after two slashes. Therefore, Rag usually did not dare to compete with Lugh. However, in order to protect his brother, Poison Fang, he had to go into close combat with Lugh. This way, he could prevent Lugh from ambushing his Brother Poison Fang.
