I Can't Cultivate Immortality, so I Can Only Use Martial Arts to Defeat the Enemies

In a world surrounded by monsters and beasts, humans are almost reduced to blood food. Fortunately, the heroic ancestors of the human race opened up the immortal and martial arts with their great wisdom. Generation after generation, people go on and on to seize every inch of living space from the minions of the demon clan. However, in the past ten thousand years, the immortal way has become increasingly prosperous, while the martial way has declined. Monsters and warriors are natural enemies. Monsters feed humans in captivity, especially warriors with strong blood. Warriors also regard monsters as food, and taking them can help their practice. The demon clan hates warriors even more than immortal cultivators! There are even rumors: Immortal cultivators are secretly hunting top warriors and refining them into yellow scarf warriors who protect the Tao! Yu Yang was born unable to cultivate immortality, so he wanted to survive in this world where monsters eat people and people eat people. Only practice martial arts! Kill the demon! Zhu Xian! Prove eternal life!
