This was the first time he had gone to rescue his fellow clansmen since entering the Outer Heaven Battlefield.
In the cave, the three people who heard that someone from the Human Clan had arrived immediately showed a look of relief, and they emerged from their hiding places. They then saw the figure at the cave entrance, radiating the same late Immortality Regainment Realm aura as them.
"Only one person?" Among the three, a handsome man looked at the lone figure across from him and was slightly stunned, asking, "Dao Companion, where are the others?"
"Others? What others? It's just me here." Cao Zhen spoke calmly. To rescue three people, three ordinary late Immortality Regainment Realm individuals, why would anyone else be needed? Besides, if others came, wouldn't they just be competing with him for the credit?
This place wasn't far from a major city of the Human Clan and could be considered a remote part of the Outer Heaven Battlefield, where top experts seldom appeared.
