Within the Heavenly Sword Sect could be found nine individuals with a cultivation level above the ninth tier of the Qi Condensation Realm. All of them were manning the 10,000 Swords Formation. As they had to keep the formation up, they were unable to directly take part in the fighting. 

Previously, Wu Yu, at the sixth tier of the Qi Condensation Realm, was able to vanquish individuals at the eighth tier of the Qi Condensation Realm. But even if he were to help to take control of the 10,000 Swords Formation, he would be unable to affect the battle significantly.

As it stood, the Zhongyuan Dao Sect had retreated from the battlefield. Only the demons and Scarlet Sea's Seven Ghosts were left. Feng Xueya was still able to hold back their strongest cultivators as a result. This was Wu Yu's best opportunity to wade into the formation and have a go at slaughtering the opponents! 

On the Heavenly Sword Sect's side, only he had the possibility of tipping the scales, as he had managed to beat Jiang Ji on his own.

Of course, within the 10,000 Swords Formation also lay the Ninth Spirit, Tian Yijun, Shen Erjun and the rest of the Seven Ghosts who could potentially suppress him, but they were held off by the duo of Feng Xueya and Lan Huayi. 

This perilous situation was definitely much more risky compared to the first time Wu Yu had raided the Zhongyuan Immortal Mountain. If he was not careful, he might be caught by someone of the tenth tier...
