How to do the task of Caraza Gate in World of Warcraft?

The task received at the door of KLz is to complete two tasks first. Later, NPC asked you to find someone in Lordaeron (this person seems to have appeared in Shacheng), and then started the task, and went to the shadow maze to find the key 1 (finally, behind the boss, it can only be triggered if you receive the KLZ door task). Trigger a "key guard" 70JY, kill it easily, get the key 1), then return to Shacheng to hand in the task, and then find the key 2 3 (key 2 is underwater in front of the steam cellar 1 boss, and key 3 is upstairs in the forbidden prison 1 boss). Boss can go up the stairs, turn right in the lobby and you will see it. Then, the task requires you to go to the cave of time to complete Medivh's touch task. First, go to the old * * * Mountain (the old South China Sea) to rescue Sal. After completing the task, an NPC appears at the last boss who completed the task, and then returns to the hole of time to pick up the next task. Go to the dark swamp to protect Medivh, 18 to guard the wave monster, 6, 12, 18 to leave the boss, then talk to Medivh, complete the task, return to the hole of time and complete the hero of the dragon. Finally, NPC wants you to go back to Shacheng to find NPC to complete the task and get the key to KLZ gate.

All tasks are not difficult, except the dark swamp. As long as Medivh's protective cover is below 0%, there is hope to complete the task. I, F, have someone to do this task, brush the reputation of the cave of time to worship, so I won't say the details.
