The Qiu village and Tang village were originally two quite large villages, both dependent on this single water source for survival.
Yet that water source was scarce and would occasionally run dry.
For the people of Qiu village and Tang village, it was a 'strategic place that must be fought over.'
When the people of Qiu village consumed more water, it meant squeezing the survival resources of Tang village.
Vice versa as well.
Due to the struggle over the water source, the two villages were in constant conflict, with clashes being too numerous to count.
Over time, the hatred between Qiu and Tang villages not only didn't dissipate but also grew increasingly intense like alcohol.
Adding to this were times of severe drought, when that small water source nearly dried up.
Getting a sip of water became even more difficult.
This intensified the hatred between Qiu and Tang villages.
