The dense and piercing sound of metal clashing echoed, and within just three breaths, a large amount of mana drained from Lin Chang'an's body.
Each Sword Aura was just an ordinary Sword Aura from a Core Formation Late Stage cultivator, but under such density, even Lin Chang'an, known for his abundant mana, couldn't endure it for long.
Yet, this ancient treasure, the Four-Symbol Dragon Scale Armor, with its golden phantom armor under such dense attacks, didn't show any cracks, merely dimming its Spiritual Light slightly.
However, with Lin Chang'an's continuous mana input, it instantly recovered.
It was clear that as long as the mana was sufficient, such dense and terrifying sword rain barrages could be easily withstood by this ancient treasure.
"Whew!"
Suddenly, the storm of Sword Aura ceased. Lin Chang'an, feeling the reduction of about thirty percent of his mana, couldn't help but marvel secretly.
