Inside the Rusted Fortress.
After a brief negotiation, Lin Yi agreed to charge the power cores for the fortress at a price of 100 Coins for each Second Level core and 1000 Coins for each Third Level core.
He essentially rented out the power cores, eventually earning 600,000 Coins.
He also agreed to charge 10,000 empty Second Level power cores and 500 Third Level power cores.
The charging price was only one-tenth of the rental fee, and the fortress would pay after the cores were charged.
Lin Yi essentially didn't have to do anything; he just needed to take the cores back to the Shelter, wait a day or two... and the cores would automatically restore energy.
The fuel issue was even simpler.
Immanuel spent 120,000 Coins to create a special device that could directly convert biomass into fuel without needing to use a bioreactor.
Next, it was time to help the fortress eliminate zombies.
