Before the Extreme Cold Came at the End, I Raided the Entire City

Li Jiujiu received a text message while working. There are 72 days left until the extreme cold hits! He thought it was a harassing text message and ignored it! Three seconds later, it popped up again. This time it's a suspended transparent panel. As he often reads online novels, he instantly realized that this seemed to be the golden finger in the novel. He asked Lao Zhang to come over and look at his phone and said the screen was black. He tried to understand this golden finger according to the routine in the novel, but it didn't seem to work. The gold finger is simple and single, it can only store things, and the space is not too large. Slowly, he discovered that this space seemed to be able to be upgraded. When the value of the stored materials reached a critical value, it would be upgraded. So Li Jiujiu, who was poor and desperate, embarked on the apocalyptic road of selling iron and hoarding supplies!
