Old demon general's plan

What made the muscular demon servant even more shocked was the words of the old general.

'Everything is according to the plan? What plan?' His mind continuously thought about the words of the old general and wondered what was that plan.

Putting these thoughts aside, what made him anxious was that the two elite demon general they had sent to the human world was killed within a few moments after they just passed through the portal.

"What do you know about planning, fool? Let me ask you a couple of questions before I say about my plan," The Old General looked at the muscular demon general with a scoff and started asking some questions.

The muscular demon nodded his head as he knew that he was not very good at thinking and that's why he took the position of the attacking and left the planning to the old demon general.
