Bab 1255: Water quality monitoring! There must be an underground river!

"Quick, check the water quality!" Qi Kaiyou immediately ordered the people around him.

The biggest reason for the sudden rise of the water level was definitely the addition of other water currents.

The water might have come from the mountains, or it might have been from other rivers.

Finally, it might be the underground river.

The underground river and the river above the ground were actually connected in many places. Therefore, the underground river could also affect the water flow of the river above the ground.

As for the exact reason, he would know after checking the water quality.

Whether it was the sudden influx of other rivers, the influx of water from the mountains, or the emergence of underground water, the water must have contained special components.

Through the comparison of these ingredients, he could roughly know what was going on.
