What's the use of killing pickaxes on the seventh day?

Seven-day pickaxe is digging. Because the seven-day pick is an efficient tool for digging holes, it can also be used to kill zombies. The iron-killing seven-day pickaxe is also used for mining, which can dig out iron, copper, silver, gold, black iron ore and black iron to upgrade weapons. Everything else is useless except doing tasks, just selling money, so killing pickaxes for seven days is used for mining.

Players can remove some iron things, such as iron shelves and ventilation pipes, to get iron, which can be refined in a furnace, and then they can make pickaxes.

Method for collecting iron chips by killing pickaxe in seven days
