In Douluo Continent, my martial soul is a speaker.

The protagonist doesn't follow Tang San, the Spirit Hall, or the Seven Treasure Glazed Tile School; instead, he builds his own power.
Meng Hao transmigrated to the Douluo Continent and was born just as an evil soul master massacred his village. His parents and the entire village were killed, but he was saved by Dugu Bo, who happened to be passing by.
So he made a grand vow to himself: to make the world free of evil spirit masters, and anyone who stood in his way would be his enemy.
There is no system, only an "ordinary" sound-based martial spirit.
First Soul Skill: Childlike Melody.
Second Soul Skill: Martial Arts Melody.
Third Soul Skill: Song of Desire.
Fourth Soul Skill: Song of Evolution.
Fifth Soul Skill: Immortal Song.
He possesses both the most powerful support abilities and the most powerful individual combat abilities.
When the enemy realized how terrifying he was.
"Quickly, smash his broken sound system spirit."
"Someone, go and gag him, and whatever you do, don't let him sing!"
This was the first thought that came to mind for everyone who encountered him, considering him his enemy.
