What exactly is it?

"Isn't it the water tower?" Zhao Yu opened the picture on his phone and re-opened the screenshot of the water tower from the video of Wei Qiqi's murder. He then looked at it carefully.

"That's true ..." Cui Lizhu came over and said,"I heard from my dad that the purpose of building a water tower in the past was because tap water was not yet universal, and the residents needed to solve the water shortage problem, so they had to build a water tower."

"It's used to extract underground water and store water ..."

"So," Zhao Yu nodded,"water towers are generally built in places where there are human settlements, in places with a dense population distribution and difficult to get water!"

"But the area around the crescent Bay is filled with water," cui Lizhu said."There is no need to build a water tower at all! People only needed to go into the river to easily get water. Moreover, this place was not a densely populated place!
