Warden Yun Ming and System Yang planned to test the personality of the human emperor. They wanted to know if his personality is similar to their master, the God of Destruction. Lord Hei Anjing is not a kind god. He is merciless and ruthless, but this is only towards his enemies. He is indifferent to strangers, but he wouldn't look down on them unless they were evil themselves. He is kind and merciful only towards children and would show respect to elders as long as it was within reason.
He knows the weakest state of a mortal and would not look down on slum people and would lend a hand as long as they were worthy of it. Even though these things couldn't affect his life, there is only one thing that can move his heart. The person he loves and the person he has chosen as his other half.
