"It's the Sand Demon!" Qing Shuang exclaimed.
The Sand Demon let out a roar, countless grains of sand shot towards Luo Chen and Qing Shuang like arrows.
They immediately cast spells and sword skills, engaging in a fierce battle with the Sand Demon.
The battle was exceedingly tough, as the Sand Demon's body could change at will, transforming into a sand wall or a sharp blade, each attack exerting tremendous pressure on Luo Chen and Qing Shuang.
But they did not retreat, knowing that only by defeating the Sand Demon could they obtain the Heavenly Crystal.
After a fierce struggle, Luo Chen and Qing Shuang finally found the Sand Demon's weakness: its heart was composed of a special sand stone.
Taking advantage of the moment the Sand Demon attacked Qing Shuang, Luo Chen rushed forward, using all his strength to stab his sword into the Sand Demon's heart.
