Amongst them,l Zhao Feng was questioned the most.
Firstly, Zhao Feng was the one who broke the array. Secondly, he was the the one who saw the Silver Striped Blood Corpse run away. Thirdly, the entire process was saw by him and him only.
This meant that Zhao Feng had seen what the others had seen and he saw what the others didn’t see. Especially at the end when everyone had just fainted leaving behind only Zhao Feng to face the corpse.
Zhao Feng’s explanation was that the Silver Striped Blood Corpses’ old injuries had once again opened and he was pushed back.
