Fengcao was also bewildered. He had never seen a mage cast a spell as quickly.
If a magic tool had been used, that would be one thing, but Du You hadn't used anything at all, he had just cast the spell. The effect from the Seal Magic Ball had just ended, and he was able to finish casting a spell instantly. What was going on?
Still, there was no time to think about it now. All Fengcao could do was focus his Dou Qi onto his body and swing his sword with all his might. No, not sword, but swords. His four arms all wielded swords, making four swings in total.
Almost simultaneously, black stars began to swirl around Du You. 512 stars spinning at high speed, so dense, it almost attracted all the surrounding light into it, shrouding the surroundings in a light-absorbing darkness.
