As Long Chen didn't want anyone to know about what was happening here, especially the Northern Emperor, he took out the Royal Commander that was sent here, cleaning the body as well.
Not a single clue was left in the clan that someone was dead.
Long Chen stepped towards the closest room, prepared to kill the most powerful beings of the clan. From what he knew, most of the people here were weaker than the Northern General. Even the patriarch of this clan was only as strong as the Northern General.
He could easily take them out.
"The door is locked from the inside," Long Chen muttered, unable to open the door.
"Time for you to get in action," Long Chen reminded the Snake Monarch, who nodded.
Snake Monarch became smaller until he was so small that he could pass through the opening under the gates.
Through the opening, he flew inside the room and unlocked the door from the inside.
