During the past few years, Su Yu had gotten the Nine Yin-Yang Sword Formation from the Mysterious Heavenly Divine Pavilion. It possessed a great might, which had helped him kill many powerful enemies.
The three small golden swords that were in his hands had been refined and created by melting the nine steel needles. It was rumored that the Nine Yin-Yang Sword Formation had been developed out of another sword formation, the Nine Suns Cosmos Sword Formation. However, the Nine Yin-Yang Sword Formation still didn't possess even a hundredth of the latter's might.
Su Yu had thought many times about this sword formation, yet he had never once imagined that he would one day witness it with his own eyes. Excitement appeared on Su Yu's face, and as he extended his hand to take it, before he even touched it, an electric current shot out of the incomplete book and numbed the tip of his finger, causing him to immediately retract his hand.
