Because only one person was killed, the backlash wasn't too severe.
Soon after, this bit of evil qi was refined by Mo Hua into the Blood Prison Pupil and the spiritual power for turning evil.
After refining, Mo Hua began to meditate calmly and contemplate the cause and effect of the evil qi, making comparisons in his mind.
Now, the source of the evil qi on him comes from two people.
One is that young man in a wolf robe, the nephew of the sect leader of the Canglang Sect.
The other is Elder Sun of the Canglang Sect.
The young man in the wolf robe was killed by Mo Hua's own hands.
Elder Sun was executed by Luo Master with a large ring blade after Mo Hua disabled his right leg and arm.
One was killed directly, the other indirectly.
Direct killing brought a much stronger backlash of evil qi.
But indirect killing, since it doesn't directly involve cause and effect, resulted in much lighter evil qi.
This is also one of the reasons why Mo Hua wanted Luo Master to kill Elder Sun.
