Superstar From Age 0 - Chapter 469:

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.”
