Li Su ran very fast, so fast that he was already beginning to flee blindly. He barely took a moment to sense the path ahead, and once he confirmed there was a passage, he charged straight into it.
He ran at tremendous speed, maintaining a pace close to the speed of light even within the deadly depths.
