The clear winter sky, which had been clear earlier, was now inexplicably shrouded in a cluster of black clouds hovering over the city center.
The Chen Family lived in a neighborhood about 10 kilometers from the city center. The location was neither bustling nor too remote; with relatively cheaper housing prices, it was perfect for the middle-income working class who needed housing. The parents of the three Chen siblings had just finished paying off the house before retiring, and after retirement, they had no debts.
"Hiss, what's up with this weird black cloud?"
Chen Haishang widened his eyes and after examining it closely, noticed the solitary black cloud seemed to be influenced by a cyclone, faintly displaying a spiral pattern.
"Dad! Is it thundering?"
Chen Fei glanced outside the window; the sky was still clear.
He guessed it might be a nearby heavy truck that had burst a tire with a loud bang that shook the earth.
