"It's been... two months, and I've finally unlocked [Intermediate Industry II]. With permanent system quests, [World Coins] sure come in fast. If I send a few more Superhumans out to kill zombies, I could probably earn 100 a day. Then... I'll max out Tinkers' Construct too!"
Shen Jin glanced at the system's [Module Store].
[Intermediate Industry II → Intermediate Industry III, cost: 1,500 World Coins]
"Ha! Twenty days at most, and I'll unlock it! Uh, Intermediate Tinkers' Construct seems to cost only 500 [World Coins]. A week would be enough."
Shen Jin shook his head and stopped thinking about that for now.
The current Tinkers' Construct equipment worked very well and had no trouble dealing with zombies, so there was no rush to unlock enhancement attributes.
He would develop the settlement first.
"Now that I have an [MFE Energy Storage Unit], that's basically a large power storage station! A [CESU Energy Storage Unit] can store at most 30,000 kilowatt-hours, while an [MFE Energy Storage Unit] holds as much as 400,000. One is worth thirteen! Not only is charging convenient, but it also takes up fewer slots when carried."
Shen Jin went to his third-floor workshop.
He took out three labeled [Industrial materials], which contained all the raw materials he needed to upgrade his industry, such as [Iron Ingots], [Steel Ingots], [Copper Ingots], [Tin Ingots], [Redstone] (graphite), [Rubber], [Diamonds], and so on.
There were also some preliminarily processed materials: [Iron Plates], [Iron Machine Casings], [Bronze Plates], [Bronze Machine Casings], [Copper Cables], [High-Voltage Cables], [Universal Fluid Units (Empty)], and so on.
There were also several obsolete machines and extras he had made, which could serve as materials in later industrial production.
"Let's make the [MFE Energy Storage Unit] first."
Electricity was the foundation of industrial development, and more advanced equipment
