Noah couldn't have precise reports about the abilities of the rank 5 cultivators of the Empire because there hadn't been a major war for a long time. After all, no one had dared to attack the Empire for centuries. The only battles happened at the edges of the areas of influence of the three big nations, but they featured rank 4 cultivators at best.
The arrival of the new continent had revealed some of its assets. Still, the majority of them had remained hidden, just as they had done for centuries.
Also, Noah couldn't decide who was his opponent most of the time, so he didn't need outdated pieces of information. A list of the abilities of most heroic assets was bound to appear after that war, but it was too early to create a proper register after only one year.
However, that lightning cultivator had snuck up on him when he was about to defeat Furious Water. Noah felt as if someone had made him lose the perfect prey, which wasn't something that his instincts took lightly.
