The Golden Core Elder, when he was a child, was gaunt and feeble, his family murdered, leaving him an orphan.
The governmental authorities didn't settle him well; every household had its own difficulties, who would dare to take in another child?
He drifted to the streets, becoming a beggar, and amidst the bullying by other beggars, he grew up.
Hatred twisted his thoughts, he swore that when he grew up, he would take revenge and repay those who had bullied him.
The desire to grow stronger also made him somewhat deranged, and during one of his begging episodes, he found himself in a place where many an immortal soared through the skies.
It broadened his horizons, and when the Immortal Sect was recruiting servant disciples, he went to test for a Spiritual Root and found out he could join the Mount Tai Sect as a servant disciple due to possessing one.
