"Sure...keke."
With his usual eerie laugh, the eerie voice agreed to Henrick's words and said, "Don't kill him but you can do anything other than that."
For the eerie voice, he just needs Henrick alive to answer his question of how he entered this minor ghost world. So, he ordered his minion to do whatever he wanted to do other than killing Henrick.
'Swoosh'
As soon as the eerie voice finished his words, an ambush ghost appeared in front of Henrick.
"Yes, master."
The rank 4 ambush ghost that appeared in front of Henrick nodded its head; however, Henrick could not see it until it entered into a range of 20 meters radius of Henrick.
'Huh?'
When the rank 4 ambush ghost appeared in Henrick's line of sight, he closely observed it.
'There are no special changes compared to rank 3 and rank 2 ambush ghosts.'
However, the ambush ghost in front of Henrick looked no different than any other ambush ghost he had seen before.
