Roaring Dragon - Chapter 50: The Gambling Saint?

“Just leave, boy. I have arranged a marriage for you, and she's a stunning beauty. Consider yourself lucky!”With his master fleeing with the money, Lin Chen, filled with sorrow and anger, left the mountain to find his fiancée. However, on the way, he was abducted by a beautiful woman who forced him to pose as her fake boyfriend. The most important thing was, this woman looked exactly like his fiancée.

In the swamp, mosquitoes danced, and a five-meter long bay crocodile was firmly bound at the snout, its vertical pupils gleaming with ferocity. At that moment, a young man cover in mud was straddling it, and he was very modest in the face of audience’s praise.“I’m Bi Fang, a professional explorer. I have trekked atop the roof of the world and traversed through the Valley of Death, and I’ve even challenged the mysterious Amazon. Even the National Geographic has named me the world’s premier survival expert, the king of the wild at the top of the food chain, but trust me, that’s all an overstatement…”Under the crimson clouds, Bi Fang silently tightened the rope in his hand and, seeing that the bay crocodile beneath him had finally stopped struggling, he pulled out the Hunting Knife and killed it with a single strike to the underside of its jaw.“Today is the second day of survival. I thought I would have to endure another hungry night, but now it seems, dinner has taken care of itself.”

A river song, triggered a legend of the rivers and lakes.
Tian Zun’s life motto: “My sword is the truth.”
Shen Lang’s life motto: “To serve people with morality, those who are dissatisfied are dead.”
