Xu Longfei said, "I remember that something major happened about 3,000 years ago.
"On the Qingyun Sect's side, in order to become stronger, a few disciples secretly cultivated a heretic technique and were willing to fall into the demonic path to become a heretic cultivator. In the end, the matter was exposed.
"However, in order to get rid of these people, Qingyun Sect suffered heavy losses.
"They did not know that these people had already cultivated to the Immortal realm.
"Furthermore, that heretic technique allowed one to burn one's lifespan in exchange for combat strength.
"Even though they had just entered the Immortal realm, as long as they burned enough of their lifespans, they could even kill Golden Immortals.
"In that battle, although the Qingyun Sect wiped out these people, they also lost a few Golden Immortals and dozens of Immortal elders. It could be said that they had suffered comparable damage while destroying the enemy.
