"By their pace, they should pass through here in about two hours. If they stop to rest for a while, it'll take even longer. With that much time, the aura of our Windblood Trees will completely merge with that of these spirit trees. When the time comes, we'll be able to catch them utterly off guard." The shorter man beside him gave a sinister smile.
"Second Brother, there are always accidents. What if they don't pass through here? Won't all our work be for nothing?"
"Wu A-Da, don't try to fool me. You refined the Mobile Wood Formation Plate long ago. Within ten li, even if it's a little off target, you can still envelop them in the formation." Wu A-Er rolled his eyes.
"Have you finished refining your formation plate?" Wu A-Da asked.
"Not yet. My mastery is ultimately just a little worse than yours." Wu A-Er rubbed his nose.
"In terms of aptitude, you're even above me. If you spent less time fooling around with the female cultivators from Scarlet Maiden Cave, you'd have finished it long ago. When the day comes that you're unable to stand against an enemy, you'll learn what it means to be too late." Wu A-Da spoke with exasperation. "If you had refined your formation plate too, the power of this grand formation would increase by thirty percent, not to mention that its shifting range would be far greater than this mere ten li."
"But aren't you here, Big Brother? I'll definitely finish refining my formation plate when we get back." Wu A-Er gave an awkward smile.
"Where is the other so-called Shadowkiller?" Lu Xiaotian frowned. After searching the surroundings, he still found no trace of this supposed Shadowkiller. Lu Xiaotian thus returned to the area where the Wu brothers had just been.
