Wiped Out My Entire Clan? I Summoned Billions of Demon Soldiers and Conquered the Heavens!

[Villain + Slaughter + Invincibility + Thrilling!] Su Mo, who transmigrated to the Primordial Ancient Realm, was born at the pinnacle of the world, the master of the Su Clan, the head of the eight great imperial clans of the Primordial Ancient Realm. Su Mo originally thought he could trample the heavens underfoot, punch emperors with his fists, and live a peaceful life. However, unexpectedly, the powerful Su Clan was wiped out overnight by the other seven great imperial clans and many other forces in the Primordial Ancient Realm. The surviving Su Mo was directly corrupted and turned into a demon. Since you are ruthless, then don't blame me for being ruthless! The Demon Soldier Summoning System arrived at this moment. Not only does slaughter yield demonic weapons, but there are also extra generous rewards—it's simply heaven-defying! And so, Su Mo, wielding the Demon Abyss Sword, surrounded by demonic energy, with billions of demonic soldiers following behind him, caused all living beings in the myriad realms to tremble in fear.
