From The Three-Body Problem to Chronicle

In the He-El Universe. He-El floated with his eyes closed before the thousand Traversal Vortices in the He-El Universe. One of the Traversal Vortices began to send back a response. He-El opened his deep eyes. A system message forged from his own mental power shot out from one of the Traversal Vortices, and He-El caught it in his hand. He-El sensed it slightly and checked the exploration of this universe's underlying logic through the system's vision.
