Global Famine: My Farm Has 10,000 Times the Harvest

A blizzard caused the global temperature to plummet to dozens of degrees below zero. Crops could not survive in the wild. Even humans faced a huge survival crisis. Suddenly, people around the world fell into terrible disasters and famine! But... What does this have to do with me? Hungry? I have a farm of 10,000 acres, and my warehouse is full of grain. I can't finish it all! Cold? I have a coal energy tower, and the farm has a normal temperature of 20 degrees, which is not cold at all! Order is broken and evil people are rampant? Haha, I have a system to join me, whoever comes will die! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
