The Black and White Stone Doors, System Mission

As Jiang Chengxuan and Shen Ruyan continued deeper into the cave, Jiang Chengxuan's intuition sensed no significant threats.

They reached an ancient stone corridor when suddenly, a wave of fluctuations arose, and a burst of dazzling light quickly approached from afar.

It was a barrage of elemental arrows, interwoven with the forces of thunder, fire, wind, and water, covering the sky and sealing off all directions in front of Jiang Chengxuan and Shen Ruyan.

At the same time, a roaring sound erupted behind them, and the ground began to tremble violently.

An ancient furnace, emitting a pale yellow hue and embodying the weight of mountains with its inscribed rules, rolled towards them, blocking the entire passage.

At this moment, with elemental arrows in front and the giant furnace pressing from behind, the situation was overwhelmingly oppressive.
