When Ji Yuan had landed in the desert, he had already replaced his Xiang Li and Anyang divine swords with Little Yui his black true divinity sword.
The reason why he had replaced his two divine swords with his true divinity sword was because only Little Yui was able to display his One Dividing Sword to its true potential.
If he had used his Xiang Li and Anyang divine swords then he would not be able to use even 60% of the true profound power of his One Dividing Sword.
And against this Iron Mountain Immortal Tie Da, Ji Yuan knows that he had to fight with his very best at the start.
Next to Ji Yuan, Destiny had also displayed her black rod of destiny while Bai Qianfeng and the Philosopher Goddess had also displayed their divine swords.
The Iron Mountain Immortal Tie Da had also displayed his divine sword as well as a wicked looking black armor as he landed not far away from Ji Yuan and his group.
