The two of them exchanged more than fifty moves before Zhao Hai's expression changed. He then launched two more attacks, and when ou Fei was retreating, he leaped back to Xia Fei's side. With a twist of his hand, the iron truncheon disappeared, and the copper ore appeared in his hand. At the same time, Xia Fei also took out the copper ore. Zhao Hai did not stop and directly threw the copper ore in ou Fei's direction. At the same time, another pile of copper ore flew over from behind ou Fei and the others, also heading toward ou Fei.
Ou Fei's eyes shrank the moment Zhao Hai took out the fire grenade. He recognized it at once, but it was too late for him to warn the people around him.
