This Immortal estate was the home of Immortal Witchriver; naturally, he had set up layers of defenses. Although he himself had perished, some of the defenses he had left behind remained usable; for example, his Dao-soldiers!
Immortal Witchriver had used up countless treasures in order to cultivate a powerful army of Dao-soldiers. In their most powerful prime, they were capable of easily killing a Loose Immortal or Earth Immortal! However, the Immortal estate had suffered through countless years of decay. Those oldest monstrous Dao-soldiers had died long ago, leaving behind a large amount of Dao-soldier armors.
