Toz sensed the tunnel straighten out after almost a couple of minutes of racing past the string of soft lights. Thankfully, the fire propelling him forward was bright enough to shed some light on the tunnel. But since he figured that he was nearing the end of the tunnel, he canceled his fire magic and let himself slow down while dispelling the armor.
It was fun going so fast, but it wouldn't be appropriate to leave the tunnel like a cannonball if he were to have a serious meeting with the general, so Toz reluctantly slowed down. And with the speed he was going, he might shoot straight into a wall and flatten himself, becoming one with the nature of a pancake if he's unlucky.
