He knew Long Tengyu and Lüqiu Shaoge weren't fully asleep, so he blurted it out.
No need for Lin Yifan to remind them, both Long Tengyu and Lüqiu Shaoge were already aware that something was about to attack them; so in the next moment, they both drew their weapons, ready for battle.
Lin Yifan also unsheathed his sword, preparing to face the fight.
Five seconds later, the first wave of blood bats swooped down, aiming for their necks.
The blood bats unleashed enormous power, their impact not less than at the Divine Transformation Second Realm Early Stage.
Of course, not all blood bats had such high strength; so Long Tengyu and the others still had the strength to fight.
Since these blood bats weren't exceptionally high in realm, Lin Yifan effortlessly swept across with his sword, killing a large number.
Before the next wave of blood bats arrived, he quickly assisted Long Tengyu and Lüqiu Shaoge, easing their burden and resolving the battle.
