Ye Fan joined the battle. Although his cultivation was still quite a distance behind that of the Yellow Emperor, combined with Xi He's cultivation, they were definitely above the Yellow Emperor.
The Yellow Emperor originally intended to settle scores with Ye Fan after killing Xi He, but as Ye Fan realized the need to ally the weak to overcome the strong, the Yellow Emperor no longer had the opportunity to kill Ye Fan and Xi He separately and instead faced the cooperation of two previously incompatible individuals.
"Ye Fan, you're courting death!" Nuwa was the first to react, intending to help the Yellow Emperor, yet even attempting to attack Ye Fan was futile, as Xuan Nu and Su Nu beside her could easily defeat her.
