Just as doubt stirred in Bo Wen's mind, Chen Mu followed up with a Fish-Belly Rebound, tracing a beautiful arc through the sky like the curve of a fish's belly. This was another highly technical aerial maneuver with a difficulty rating of 70. Bo Wen was utterly dumbfounded.
Multi-tier tactics combined several aerial maneuvers into a continuous sequence. A sequence containing two aerial maneuvers was called a dual-tier tactic; one containing three was called a three-tier tactic, and so on. Although Bo Wen was not a Close-Combat Card Adept, he understood these fundamentals. If a dual-tier tactic contained two maneuvers rated at 60, its difficulty far exceeded that of a single maneuver rated at 70. Thus, the multi-tier tactics ordinary Card Adepts used mostly consisted of simple aerial maneuvers with very low difficulty ratings.
With two consecutive maneuvers rated at 70, the difficulty of this dual-tier tactic reached a truly terrifying level. Bo Wen was now completely certain that Chen Mu was a Close-Combat Card Adept.
Cheng Ying, watching from a distance, was startled as well. This was the first time she had ever witnessed a dual-tier tactic of this caliber, composed of two maneuvers rated at 70.
Bo Wen found that he could not lock onto Chen Mu at all, and the Wave Blade in his palm remained unfired. If a ranged Card Adept missed the first attack, his confidence would suffer to some degree. That was why experts rarely struck rashly. They always waited patiently for an opening; if they struck at all, their strike had to land.
Bo Wen was clearly an expert.
He waited, waiting for Chen Mu's Fish-Belly Rebound to end.
The Fish-Belly Rebound demanded exceptionally precise control of the Airflow Card, as its difficulty rating of 70 clearly demonstrated. It required a Card Adept
