The sword Qi formation shows its might (1)

Just as his Iron Fists were about to fly out of the cave, Zhao Hai suddenly felt that his spiritual power had been cut off. He seemed to have lost contact with his Iron Fists. This shocked Zhao Hai, but he quickly calmed down. He knew that the spiritual power connection between him and his Iron Fists could not be cut off so easily. Something must have happened. What exactly happened?

Zhao Hai furrowed his brows. After a while, he suddenly thought of something. Could there be a barrier formation? if there was a trap formation there that could be activated, there would naturally be a barrier formation that could be activated. If the barrier formation was activated, it could really cut off the spiritual power connection between him and iron Fist.
