Cooling pillar #1
Now you need to go back to the second platform as this one has the first cooling pillar that you need to destroy. The central device has four vents that open randomly, and when they are open you can shoot them to destroy them. Once all four are shot, use the launch pad to reach the next area.
Cooling column #2 and #3
Once you land on the new platform, you'll want to remove the Totality Enforcer and immediately turn around to find another terminal to interact with. This will open three more cooling tower control fuses on the left, right, and center towers that you can destroy.
With these fuses destroyed you can now shoot the 4 vents on the cooling pillar to the left and right. When they are destroyed, it's time to go to the path to the left, where the room is full of Legions to kill. When they are dead, interact with the terminal that says “WARNING: OVERLOAD” and take the launchpad to the next area.

When you see Dredgen Bael's shadow, you can safely ignore it and instead look to the left to see hive lanterns that you can jump on. Your goal is to climb all the way to the other side and up the platforms to reach the red room where you can drop down to the ledge on the other side and enter the room.
Go down the hall to find Bael's shadow again, but the room you enter will be locked. Turn around and look down the hall and you can find a crack in the stairs to fall down find another area. You can now continue on your way until you find the Soulfire Barrier.

How to beat Valus Tau'rig in Destiny 2
You will now be in a boss encounter against a Valus Tau'rig who uses Cull's Shadow. Valus has a first phase where you just have to fight him as normal. However, before you can kill him, he is corrupted by the Hive Wizards, thus beginning his next phase.
To defeat Valus Tau'rig you have to kill the ads until you see the text “Seeking source of soulfire”. Now, in either the left or right room, there will be Pyre Matrons and a Soulfire Vessel. Just kill them and ignite one of the three borders with Soulfire Charge to trigger his shields.
For the other half of his health, you'll need to use Soulfire Charge on two borders, so follow the Hive Wizards into the ritual room and kill them so you can then kill the Soulfire Vessel. When Valus Tau'rig is dead, you can get Cull's Shadow Exotic.
You can now end the exotic mission by heading to the center of the room before you fought Valus and interacting with the circle.
