However, they could not add too much of the special material discovered in the ancient cultivator city to the flying swords. Otherwise, the swords would grow too heavy and lose their nimbleness, making their true nature easy to spot.
If that happened, crafting them in the shape of flying swords would be pointless. They would no longer serve as a surprise attack. So Shuang Qingqing had added a little of the special material only to each sword's core.
In today's fight against Calamity Son, Shuang Qingqing had used Flying Sword Puppets twice. The first wave consisted of ordinary Flying Sword Puppets. Besides attacking Calamity Son with venom, they were meant to lull him into complacency—though poisoning him would have been better still.
For the second wave, she would use Flying Sword Puppets made with the special material. That was when her attack would truly begin. If Calamity Son treated them the same way he had treated the first wave, Shuang Qingqing was forty percent certain she could tear through his defenses.
Once eighteen of those special-material Flying Sword Puppets formed a formation, their combined force could pierce Calamity Son's defenses. Shuang Qingqing had grasped the principles behind its operation from the eighteen Arhat Statues.
Though they lacked the power of faith, the eighteen arhats could form a perfect closed circuit that compounded their strength, meeting the requirements of the smallest Lesser Arhat Formation. Without that power's support, its might was reduced, but it was still a form of Puppet Arts.
