Chapter 638 The Hidden Immortal Valley

• "There's a battle happening over there." As they approached, they spotted a familiar figure, a woman surrounded by divine light.
• Behind her, a pair of white wings extended, resembling an angel engaged in combat with a dragon. The woman was none other than Yuxi, whom they had encountered previously.
• The dragon that Yuxi was facing was hundreds of meters long, covered in scales. Given Yuxi's strength, defeating the dragon should have been a simple task.
