"Be vigilant!" Bai Xueyan immediately shouted, drawing out his weapon, a high-level talisman, Mo Xiao.
His sensing expanded instantly.
He understood clearly that worthily reminding by a passing Grandmaster indicated that this wave of attacking Demon Race was particularly perilous.
As if confirming his thoughts, soon all martial artists detected the tremors coming from the ground.
