The spiritual veins of Qinglan Mountain are abnormally changing, and the thousand-year-old trees are damaged one after another. The reclusive wood monk Luo Musen repairs the spiritual veins alone, but he is encountered by the traveling swordsman Mu Zibu. The two met for the first time and had a rift due to "outsider intervention." Later, they discovered that the damage to the mountain spirit was closely related to the massacre of the village at the foot of the mountain - someone set up a soul-eating array in order to extract the soul and awaken the Xuan Yin evil suppressed under the sycamore tree. In order to protect Qinglan Mountain and the people at the foot of the mountain, Luo Musen used the power of the wood spirit to stabilize his spiritual veins, Mu Zibu held his sword to kill evil and broke the formation, and the black jade pendant transmitted spiritual power to fight against the mysterious evil. After the crisis was over, Mu Zibu was willing to stay in the mountain and walk with him. In the mist of Qinglan Mountain, the two heroes' hearts have been side by side since then, and the road of protection has just begun.
