Ye Xiao immediately guessed why Xue Bing asked Ye Xiao to bring back at least a single drop of Immortal Origin Liquid. It is because she needed this liquid to heal her injuries and only Ye Xiao has the strength to get this treasure from the Double Sword Sacred Land.
In other words, she wanted to use Ye Xiao's strength for her own gain.
"Master?"
Xue Xiaofei was also surprised when she heard her master's words. She could not believe her master, whom she treated just like her own mother, was asking Ye Xiao to go to the Double Sword Sacred Land and bring back at least a drop of Immortal Origin Liquid.
In her eyes, although Ye Xiao was able to kill Hu Jintao, an Early Dao Tribulation Stage martial artist, it doesn't mean he has the strength to face the Double Sword Sacred Land of the Great Martial World.
