Xu Yuan was indifferent. He cast a black shield like a dome above Su Wan's head. The sharp arrows couldn't pierce through the shield.
It was clear that only the Blazing Night Elf Archers were of use in this fight. Others couldn't fight at all.
Su Wan turned to the hollow core, which was protected by the twelve huge blue crystals. Xu Yuan's shield withstood all attacks and kept her safe, allowing her to approach the hollow core.
The mermen were terrified. They shot arrow after arrow to stop her, but the shield repelled them all. No matter how sharp the arrows were, they couldn't pierce through the shield of dark energy.
When the shield almost broke, Xu Yuan condensed more energy to add to it. It held fast.
'Thankfully, Xu Yuan is strong!' Su Wan was very grateful for his help.
