From a rational point of view, Chu Nan's best choice was to retreat and avoid them without continuing to fight.
Rudy Karl was able to closely follow Feng Mingxi to the second place a few days ago and even complete the counterattack more than two hours ago. Even with the help of his companions, his strength was definitely very powerful.
Just from his casual posture, it could be seen that his foundation was solid and his martial technique was proficient. He was definitely not to be trifled with.
If Chu Nan insisted on fighting him here, not to mention whether he could win, he would definitely waste a large amount of time. In the situation where he should race against time to hunt ferocious beasts to increase his points, it was undoubtedly extremely inefficient and the worst choice.
