Xu Junxiao, a century-old Taoist priest, watched for decades, waiting for the return of his three brothers who came down to fight against the Japanese, until the founding of New China. He went down the mountain under the pseudonym of Dr. Xu, a traditional Chinese medicine doctor, and hung a pot to help people while looking for traces of his senior brother. On the way, he resolved the danger for Lu Wanwan, who was pregnant with an alien child, and found the souls of three senior brothers in the barren mountains, private houses, and old churches. The eldest brother Bu Shi was trapped in the barren mountain while fighting against the enemy, the second brother was obsessed with awakening the villagers to avoid the bandits, and the third brother indulged in illusions to steal medicine to save people. Xu Junxiao finally transformed the heroic souls of the three senior brothers, allowing the martyrs who sacrificed their lives for the country to rest in peace, remembering their righteousness to protect the country and the people with their mortal bodies.
