Seeing this, Yuna, who was behind him, did not hesitate at all. She directly bit her lip and spat out a dense blood essence.
As she spat out this mouthful of blood essence, Yuna's face instantly turned pale, and her expression directly withered.
However, Yuna did not waste any time. She directly used her dark power to envelop the blood essence in her hand.
The blood essence in her hand instantly transformed into a dense dark power that enveloped her and Lu Yan's bodies.
Thick black trees spun out from the ground and quickly climbed up Lu Yan and Yuna's bodies, directly enveloping them.
The flames Ao Yun spat out landed on the black tree, instantly roasting the bark. However, the black tree isolated a large number of flames, preventing Lu Yan and Yuna from being injured by the flames.
Ao Yun looked at the black trees that surged out in front of him, his eyes revealing hidden hatred.
