"Under someone's roof, one must bow their head," Yusuf Zuck had no choice but to grit his teeth and go up the mountain to pull wild vegetables since he couldn't defeat the White-Haired Witch and couldn't leave the Campbell Sect.
Indeed, the wild grass the White-Haired Witch mentioned was actually chives, similar to those in the secular world, but taller with a touch of Spiritual Energy.
Yusuf Zuck had tasted a leaf before, and it was undoubtedly chives, even a million times better than those in the secular world.
But since Aiden Wilkinson said it was wild grass, it could only be wild grass.
While pulling the grass, Yusuf's chest still hurt since Aiden had struck him hard, shattering his heart and causing massive internal bleeding.
Of course, what Yusuf didn't know was that Aiden had deliberately made that strike, and while Yusuf was enduring the pain on the mountain pulling grass, Aiden was constantly monitoring him with Divine Sense Exploration to see what elixir he used.
