Even if Zhao Hai didn't use those Buddhist techniques, his current attack power was still very strong. With the twelve metal beasts and those Flying Needles, although the people of the treasures world had gradually gotten used to the attack of Zhao Hai's Flying Needles and started to organize some resistance, a large-scale resistance had not been formed. Because of the twelve metal beasts, as long as the people of the treasures world gathered together, the twelve metal beasts would immediately attack them. It was only over when their formation was scattered.
The Xu people didn't stay idle either. They kept attacking the people from the world of a hundred treasures. Zhao Hai didn't manage to hold off many people from the world of a hundred treasures by himself. There were only about a hundred or so people. This was Zhao Hai's limit, and he only managed to do so with the help of the twelve metal beasts.
