After a while, the group of five (including the King's bodyguard) reached the central tower, which was quite smaller and leaner compared to the others.
Like the other towers, which have training grounds of various levels on different floors, this building also had different levels inside.
The only problem is that the tower cannot always stay open. Hence, once Vesyrn and Izora enter the tower of time/ancient time chamber, unless they were out, no one else can enter. Of course, the King can forcefully pull them out using his blood at any time. So, in times of crisis, he will be helpful once again.
Anyways, as the group stood before the entrance, the King proceeded to walk toward a handprint on the left side of the door. He then smeared the handprint with his blood and inserted his soul energy.
