The ghostly passage twisted violently. Vast amounts of the deathly cold upon its surface evaporated beneath the thunderous bombardment, giving off piercing hisses.
The will on the other side seemed enraged. It let out a soundless roar, and more grayish-white cold surged forth, stubbornly resisting the lightning.
"As tough as I thought!"
Li Yunjing's gaze sharpened. He could sense that the passage itself seemed to contain some extremely advanced law of ice, granting it formidable resistance to energy attacks.
"Then if one strike isn't enough, I'll give you ten! A hundred!"
At his command, the Divine Firmament Thunder Seal above his head blazed with light. Bolts of Chaos Divine Thunder, thicker and darker than before, poured down like a torrential rain, relentlessly hammering the same spot!
Boom! Boom! Boom! Boom!
Deafening thunder resounded across the northern lands, and dazzling lightning lit the gloomy sky.
The scattered shock waves cracked and melted glaciers for dozens of miles around!
Under this dense, savage bombardment, the ghostly passage finally buckled. Its surface glow rapidly dimmed, and distinct cracks began spreading through its warped structure!
For the first time, the icy will on the other side conveyed a trace of shock and fury.
"Now!"
A fierce glint flashed through Li Yunjing's eyes. He slammed his hands together, concentrating all his thunder power into a single point!
"Divine Firmament! Nirvana Thunder Strike!"
A dark-purple lightning spear, only as thick as an arm yet condensed to the utmost, formed at the center of the thunder seal. Countless tiny worlds of lightning seemed to be born and perish within it. Bearing a terrifying aura that could pierce the void and annihilate everything, it shot straight into the weakest point at the passage's center!
Pop!!!
There was no earth-shaking explosion, only a soft sound like a bursting bubble.
