Yu Xuanji watched Lin Shen finish everything without intending to stop him.
Lin Shen's series of maneuvers allowed Yu Xuanji to observe and judge his strength, which is why Yu Xuanji did not intervene and let him act freely.
Immortals become more cautious with age, with death tribulations hanging over them like guillotines, the more tribulations they experience, the more they cherish their lives.
Despite Yu Xuanji's exceptional strength, with few in the cosmos capable of surpassing him, he still maintained enough patience and caution when facing those unfamiliar to him.
There were few in the cosmos who could kill him, but the Cosmic Laws were countless, and no one knew how many types of Law Power could harm him.
For immortals, injury was also a dangerous matter; anything that might affect Yu Xuanji's passing through the death tribulation was to be avoided as much as possible.
Watching Lin Shen treat Yu Yan's injuries, Yu Xuanji looked somewhat surprised.
