"Wei Yun, you go ahead and wander around the Heavenly Merchant Clan, I'll study their Chaos Array here." Xu Fan communicated.
"I would rather wait for you here." Zhang Weiyun replied.
Zhang Weiyun looked at Xu Fan who was sitting cross-legged above the Big formation, a look of admiration in her eyes.
Xu Fan was beginning to get puzzled, according to his and Grape's inference, this Big formation would not naturally malfunction.
After years of theoretical speculation without results, Xu Fan could only open his eyes in resignation, looking at the two Chaos Great Saints from the Heavenly Merchant Clan waiting around him.
"So, have you found the cause?" the Chaos Great Saint from the Heavenly Merchant Clan asked Xu Fan hopefully.
"It's strange, all the factors that can interfere with this Big formation have been considered, but I haven't discovered any traces of these factors."
