Archaeological Live Broadcast: Weird Knocking Sounds Coming from the Bottom of the Water

The archaeological team conducted a live broadcast of the site at the bottom of the lake, and the official beauty host whetted the appetite. The barrage flooded the screen to grab my wife, while I squatted on the construction site and ate instant noodles. Black water suddenly spewed out of the drain pipe, and there was a tapping sound from the bottom of the water. I picked up the shovel and jumped in. A pale hand was dug out of the mud, still moving.
