Why is there no death tower in my DNF?

The tower of death was renamed "the tower of despair", and the access method is as follows:

1. Turn on the computer, log in to your account of Dungeon and Warrior, and select the character who needs to brush the tower of despair.

2. When entering Zeilya's room, the character goes to the right and enters the portal, and selects "Alvin Line".

3. After the character enters the Alvin defense line, open the small map and you can see the map of Death Canyon.

4. The character walks to the right, enters the entrance of "Stone Snow Area", then walks up, and stops when he sees NPC soothsayer Xinmeile Co., Ltd.

5. When the character enters the dungeon to the left, you can see the tower of the desperate dungeon, and you can choose to enter.
