Sun Kang was merely the young owner of an inn when he unexpectedly obtained a Thunder Pearl capable of summoning wind and rain.
The Thunder God appeared and asked Sun Kang to protect the pearl and become its master. In return, the Thunder Pearl would keep Sun Kang safe and at peace for the rest of his life.
With that,
the Thunder God disappeared.
Left with no choice, Sun Kang agreed to the Thunder God's request and hid the tiny Thunder Pearl in the most secluded corner of his inn.
Before long,
the pearl's spiritual power attracted the attention of demons and monsters, all of whom wanted to claim it for themselves.
Sun Kang was only a mortal, and at first he couldn't control such powerful spiritual energy. Fortunately, Tang Xiaoxian secretly helped him, saving him from making a complete fool of himself.
As one incident after another unfolded, Sun Kang gradually discovered that the Thunder Pearl had been protecting him and keeping the inn safe all along. More importantly, it had already acknowledged him as its master.
From then on,
Sun Kang secretly used the Thunder Pearl's power to help those around him and subdue the demons and monsters who sought to devour it. After doing enough good deeds, he earned the Thunder God's approval.
Just as the Thunder God was about to pass the Thunder Pearl on to Sun Kang, Sun Kang discovered a shocking secret about it.
