The protagonist Lin Yan travels through the wilderness and becomes "Yan", an ordinary witch boy from the Houtu tribe, and obtains the "Immortal Human Shield System". In the Witch Clan, which advocates offense, his talent of "getting stronger after being beaten" is regarded as useless. With the wisdom of modern people, he kept a low profile in the early stage, silently piled on the thickest armor and endured the most severe beatings. In the shocking battles, when everyone thought he was bound to die, he counterattacked with invincible defense and terror, becoming the strongest human shield in the world that even the saints could not shake. Finally, he paved a new path for the Wu Clan to prove the Tao through strength and become a saint in the flesh.
