It took him half a year.
Qin shujian had already killed all the evil demons in 153 of the 176 true domains in North cloud Manor.
In the remaining true Dominion.
Only 23 were left.
He secretly estimated the number of sinister Devils in the remaining true Dominion.
Qin shujian already had a rough idea in his mind.
There are 53 sealing altars in the 23 true Dominion.
according to Marquis northcloud's information, there are about 78 sinister Devils in the 53 sealing altars.
"In this case, it should be enough in about a month or so."
With his rich experience in dealing with sinister Devils, he could easily deal with them.
Unless it was a sinister devil with an eight-star formation or higher.
Otherwise ...
The other demons wouldn't be able to last long in front of it. Only the demons with the eight-star formation and above couldn't be dealt with by the formation alone. That was why Qin shujian had to take action personally.
