"Xu Nian, take this!"
Sword Mark Immortal Venerable's eyes were sharp, mobilizing the powerful Immortal Essence within him.
The Thunder Attribute Law also surged forth.
Countless Thunder Attribute Law Power continuously merged with Immortal Essence, finally forming an extremely terrifying Thunder Sword.
The power of this Thunder Sword was exceedingly domineering,
everyone watching around could feel a heart-palpitating wave.
If this Thunder Sword were to charge at them, they would definitely be doomed.
Even Master Wind Snow lamented, "The strength of this Sword Mark Immortal Venerable has improved quite a bit. The power of this Thunder Sword is much stronger than when he fought me before. I'm afraid even I would have to use all my skills."
Hearing this, Mu Yan's expression turned even more serious.
She was well aware of Master Wind Snow's strength.
Even Master Wind Snow needed to use all his strength; the strength of this Sword Mark Immortal Venerable is truly extraordinary.
