Mo Lian had ordered every fortification to construct their own reservoirs to cope with any unexpected events.
He had also sent people tasked to guard the water sources, but unfortunately, the results were not good as people had still tampered with them.
The reservoir was not too large, but it was adequate as an everyday water reserve.
"There are a total of three such reservoirs in the city?" Qiao Mu tilted her head to ask that disciple who had discovered the reservoir.
"Mhm-hm." That disciple nodded repeatedly. He pinched his nose as he walked to one end. "It's so d*mn stinky. Look at the water within. It's basically a combination of sludge and filth."
Qiao Mu nodded. "If they poisoned the water sources simultaneously, they must have sent several batches of people to carry out this operation."
