This is an easy one. As you complete the Parkour Section you come to a fork in the path. Take the left passage and you'll see a Conflux, activate it. Above you will appear 4 boxes, but wait for a tinier one to appear informing you of the order to shoot them. After the last one, 4 more will appear in front of each teleporter, same drill, wait for tiny to direct you. That's it, done!
