Ancestor Luo, a native of Jimo, Shandong, was poor in his youth and enlisted as a soldier in the north to guard the frontier. After living in the north for several years, Ancestor Luo fathered a son, and his official career subsequently prospered, earning him high regard from his superiors. Later, his superior was promoted to Deputy General and assigned to Shaanxi. Ancestor Luo traveled with him, entrusting his wife and child to the care of his friend, Mr. Li, before leaving.

On one occasion, his superior dispatched Ancestor Luo to deliver a message to the northern frontier. Before setting out, Ancestor Luo made a detour back to his hometown. Upon arrival, he found his wife safe and sound, but noticed a pair of men's cloth shoes beneath the bed. A suspicion immediately took root in Ancestor Luo’s mind: "Could my wife be having an affair? The lover must surely be that fellow Li." Without a word, he gathered his wife and proceeded to Mr. Li's residence, ostensibly to express thanks, but in truth, to verify his suspicions.

Mr. Li came out to greet them, his demeanor warm and hospitable, and soon laid out a feast. During the meal, Ancestor Luo’s wife praised Mr. Li’s loyalty and kindness ceaselessly, her eyes exchanging flirtatious glances with him. Ancestor Luo’s heart grew utterly cold, and he remained silently withdrawn. The next day, Ancestor Luo told his wife, "I must travel to the frontier with this dispatch and won't be back tonight, so don't wait up for me." He then rode away, but an hour into the first watch, he quietly doubled back.

Ancestor Luo crept stealthily to the window. He could hear his wife's melodious and coaxing voice from within, laughing intimately with Mr. Li. Ancestor Luo, enraged, burst through the door. The pair were overcome with terror and fell to their knees, begging for mercy. Ancestor Luo drew the saber he carried and held it to Mr. Li’s throat, but suddenly spat on the floor, retracted his blade, and said coldly, "A beast like you would only sully my weapon. Listen closely: if you wish to live, you will grant me two requests. First, take care of my wife and child. Second, take my place in the army." With that, he strode out and departed.

The neighbors reported the incident to the magistrate's office. After a thorough interrogation, Mr. Li confessed everything truthfully. The magistrate was furious and immediately ordered that Mr. Li and the wife each be given fifty strokes of the heavy staff before being imprisoned. A year later, both died. As for Ancestor Luo’s son, he was sent back to his hometown and handed over to relatives in Jimo County for safekeeping.

Since that departure, Ancestor Luo vanished without a trace. Later, some woodcutters claimed to have seen him in the wilderness. At that time, he was seated in meditation within a cave, abstaining from both food and drink all day long. When offered dried rations, he refused them. He remained unmoving for several years, the weeds growing thick outside his cave entrance. After a long while yet again, someone saw Ancestor Luo walking in the mountains, but upon approaching for a closer look, he vanished in the blink of an eye. Investigating the cave, they found Ancestor Luo covered entirely in dust, his physical body long since transformed through seated dissolution—it was surmised he had achieved immortality.

The villagers, to commemorate Ancestor Luo, built a temple specifically for him, and every March, they held regular ceremonies of worship. Sometimes, Ancestor Luo’s son would visit the temple to pay respects to his deceased father. The locals would call him "Little Ancestor Luo" and eagerly presented him with incense money and offerings.
