Although at the time, with the strengths of Wu Bubai, Wu Buhuo, and others, killing Xiao Rugu wasn't difficult, it could even be said to be very simple.
Yet, the "Great Demon Heart Sutra" was indeed unfathomable and unparalleled.
Back then, Xiao Rugu was clearly killed on the spot, but it wasn't long before news of Xiao Rugu emerged again in the Small Thousand World.
Xiao Rugu mysteriously resurrected from the dead.
Then, led by Wu Bubai and others, members of the Martial Sect consulted countless ancient texts, and only then confirmed one thing - cultivating the "Great Demon Heart Sutra" to a certain depth would give rise to a Demon Heart.
Those with a Demon Heart, as long as the Demon Heart isn't completely annihilated, can resurrect from death.
Moreover, the Supreme Martial Realm itself has resurrection effects.
Since then, Xiao Rugu became the shame of the Martial Sect.
For tens of thousands of years, members of the Martial Sect dreamt of killing him.
