Ye Chong hid behind a damaged part of the wall and peeked out from behind to look outside.
About a dozen golden colored mechs whizzed past the sky. The sound was from their speedy flight across the air. Their velocity slightly surprised Ye Chong. The mechs must be flying at no less than Mach 17 or 18. After all, they were now within the atmosphere. It it was in outer space, even reaching up to Mach 20 was not particularly difficult.
To think that he was lucky enough to see their advanced mechs just as he arrived in Gray Valley! They mechs were now vanishing dots in the sky. Ye Chong watched them in a daze. It was a pity that they flew so fast that he could not make out what they looked like. However, their dazzling gold left a deep impression in him.
Ye Chong returned to Mu and Han Jia's side still thinking about the golden mechs. However, he quickly composed himself and began to work on the technical issues that he was facing.
