MTL - My Beloved Concubine Only Wants to Eat Melons - Chapter 9

I became the childhood friend of the protagonist in a novel. The childhood friend who died from taking drugs.

It begins on the mountain.

With the glint of a knife, a flash of steel in the hands of a sworn brother. A betrayal.

Stabbed and pushed down the mountain, Zi Chen lied within the red-stained snow, left to die.

This is where it begins; he is given life by lightning,
baptized by thunder.

Those who had once betrayed him should all suffer in his cruel revenge.
