As the proverb says, violent ones fear those who do not consider anything, and those unconcerned ones fear those who would risk everything.
When Xin Tianwu and Lei Yue ignited their divine souls in battle, even the Genuine Supreme Dao elite warriors would more or less restrain their fear to some extent. After all, no one would be willing to encounter such relentless opponents. For such a suicidal battle tactic, it could kill a thousand or even take out eight hundred of their own.
If this were the case, they would have extreme difficulty continuing the attack on the Qin Clan.
Qin Wushuang would not dare to neglect them as he fought back with the Heavenly Emperor Sword. He extracted the Nine Dragon Layered Flame and provoked them with a ball of fire to stop Xin Tianwu and Lei Yue's momentum.
