What do you mean by my awakened profession being Monster Hunter?

Qi Shi'an unexpectedly transmigrated to this nightmare-level world.
Fortunately, he had a seed of the Myriad Paths Tree.
During the baptism, the Tree of Ten Thousand Paths was unexpectedly activated.
In the end, however, he discovered that his Myriad Paths Tree seemed to be somewhat different.
When the Tree of Ten Thousand Paths not only provides cultivation resources but also grants him the ability to control the laws of heaven;
It can also absorb the spiritual blood of ferocious beasts, restore it to its original state, and transform it into a precious technique.
A different idea began to form in Qi Shi'an's mind.
......
In order to nourish the Myriad Dao Tree to grow rapidly, it wreaked havoc in the Void God Realm, staining the Hundred Broken Mountains with blood.
In order to survive, he did not hesitate to throw himself into the chaos of the world, transforming into a great demon of the heavens, staining the sky with blood!
With an immortal demonic body, he looked down upon the world and forged a holy name for all ages!
At the pinnacle of demons, amidst the chaos of the world, where I, the Demon Lord, exist, there are no immortals!
Heavenly Demon Halberd, True Demon Armor, slaughtering all immortals and leveling the heavens!
Qi Shi'an: I am the Primordial Demon Lord, and I shall slay all enemies in the world!
