Mo Feiyang and Mo Wuying embark on a journey to the hermitage of their uncle. They crossed the rolling mountains, crossed the winding streams, experienced the wind, frost, rain and snow along the way, and also saw the prosperity and desolation of the south of the Yangtze River. The two brothers and sisters have very different personalities, Mo Feiyang is bold and straightforward, and Mo Wuying is delicate and sensitive, but the relationship between them is unusually harmonious.
One day, they came to a small town called "Lihuo". Nestled in a vast valley surrounded by volcanoes, the town is said to have been a lava field long ago, before the volcano went out, leaving behind a wealth of minerals and unique landforms. Hence the name "Lihuo", which means to be born out of the fire.
The townspeople live a simple life and make a living from mining and farming. However, something strange has happened in the town lately. Some say that at night they hear a roar from the ground as if something was moving, while others say that strange lights and shadows appear in the depths of the mine, as if some unknown force is at work.
When Mo Feiyang and Mo Wuying entered the town, they happened to meet the people of the town who got together to discuss these strange things. The siblings didn't want to be nosy, but after hearing about these strange phenomena, their curiosity was piqued. Especially Mo Feiyang, he has been full of yearning for various adventures since he was a child.
They decide to stay in town for a few days to find out the truth about these things. At night, when most of the villagers were already asleep, Mo Feiyang and Mo Wuying quietly went to the mine. In the moonlight, the outline of the mine looks particularly eerie, and the surrounding air is filled with the smell of sulfur.
They cautiously descended into the mine, only to see that the inside of the mine was intricate, and the ore on the walls shimmered strangely in the light of the fire. As they went deeper, the roar from the ground became clearer and clearer, as if something was brewing in the depths.
Suddenly, a violent tremor spread throughout the mine, and with a loud bang, a boulder slid down from above, heading straight for Mo Feifei. Mo Wuying reacted extremely quickly and grabbed his brother, and the two narrowly avoided this deadly attack.
They realize that these strange things are not simply natural phenomena, but must be hiding some kind of secret behind them. And this secret may have something to do with the treasure mentioned in their father's secret letter.
Just as they were about to continue their investigation, a figure suddenly appeared in front of them. It was an old man in a gray robe, and his appearance was silent, as if he had been born out of darkness. The old man's eyes were deep, and through the dim light of the fire, he looked at the brother and sister, and a mysterious smile appeared on the corner of his mouth.
"You're from Mofu, aren't you? Your father, Mo Qianyu, is a great person. The old man's voice was low and penetrating, echoing through the mine.
Mo Feiyang and Mo Wuying glanced at each other, they knew that the appearance of this old man would bring a new twist to their fate. And the story of "Leaving the Fire and Returning to the Ruins" has only just begun.
