"Luckily, I didn't bump into a plane!"
Gu Yu descended somewhere above Shanxi Province and landed on a small hill. Shooing a few mutated big rats away, he sat down to adjust his breath.
He used to joke with Xiaozhai about knocking down a plane, but the worry had become true in a mere couple of years. In that sense, the ancient times were much safer—the sky was clear and there were no big flying machines he would need to look out for.
His destination this time was the city of Dakang below Tianshan Mountain. The flight from Shengtian to Urumqi would take him over ten hours, stopover time included.
Turning into a flashing sword and flying there himself would certainly take much longer than that, for he had to land and take a rest whenever the consumption of his spiritual essence had reached the threshold which the speed of recovery could not catch up.
It was much more troublesome this way, but he still chose to fly.
