Zhou Danqing spoke up, "Qin Hao has comprehended profound Thunder Rule; he can easily kill you all with just the Thunder Rule. Those who comprehend the laws of nature are invincible in the same realm unless their opponents also comprehend some sort of natural laws."
"Comprehending some sort of natural law makes you invincible in the same realm?" someone said in surprise.
