But since he has an idea, he must carry it out to the end, Fang Ling opened his eyes wide, pulled out his dagger, and stuck it on the rock with one step, so as not to be washed away, the river is rushing forward like a waterfall, and he doesn't know where it leads.

From time to time, a thick layer of aquatic plants spreads out from the bottom of the river, floating down the river like human hair, and it is really a little terrifying at the bottom of this gloomy river.

Fang Ling walked all the way along the riverbed, and found that the river is getting wider and wider, and according to this direction, it seems to be able to lead to the Jinsha River outside the city, and the water of the Jinsha River is also notoriously urgent, many people are drowned every year, if they rush into the Jinsha River, they are buried by the sediment, and they are afraid that no matter how hard they try, it will be difficult to find.

After looking for a long time, calculating the time for the camp to be guarded, Fang Ling had to sigh secretly, and when he was about to leave, he was suddenly attracted by something in front of him, there was a dense mass of aquatic plants, wantonly winding a few rocks, and there were clearly a few strips of rags on the rocks, because the strips of cloth were azure, similar in color to aquatic plants, so Fang Ling didn't notice it at first, but fortunately he took a look before leaving, and then he found something strange.

He hurriedly swam over, pulled out those aquatic plants, and was immediately surprised, the thing that this aquatic grass was entangled in was nothing else, it was actually a stone man!

The cold stone man didn't know how long he had been under the water, his body was covered with moss, but he could vaguely distinguish the frightened expression revealed on that face, his eyes were wide open, staring at Fang Ling with horror, the pores on his face could be seen clearly, and this state was almost exactly the same as the petrification of the Bai family.

Face to face with such a stone man under the water, if ordinary people are afraid that they will even be scared out of their hearts, but Fang Ling has always been bold, and after being stunned for a moment, he immediately calmed down and carefully observed the stone man.

The strip of cloth on his body is exactly the clothes he is wearing, and there is a white jade buckle belt around his waist, and the word "inscription" is suddenly carved on the jade.

Isn't the missing son of the Zheng family called Zheng Ming?

Fang Ling almost subconsciously thought, could this stone figure be Zheng Ming?

He immediately looked around again, and actually found another stone man, Fang Ling was holding his breath at this time and was almost to the limit, he picked up the two stone figures and walked against the current, it took a lot of time to return to the mine, put the two stone men up, Fang Ling found a jade pendant engraved with the name of the stone man on the clothes of the stone man behind, and immediately judged that this stone man was the missing son of the Wu family.

Finally found the two sons, Fang Ling was greatly relieved, but at the same time, a bigger question arose, why did these two people sink to the bottom of the river like stones?

After thinking about it for a while, he suddenly understood that his judgment should be correct, Zheng Wu and his two sons decided to find their own way because they couldn't wait for rescue for a long time, so they dived into the underground river, trying to find a way out by the river's downstream, but they didn't expect that they suddenly petrified halfway and finally sank to the bottom of the river.

In other words, in the end, all four sons were petrified.
