"Blood crystals! Use the extractor to extract the energy from blood crystals!"
Those words snapped Shen Jin out of his confusion. He had never figured out how to use the energy in blood crystals, but now he suddenly had an idea.
Use technology to study supernatural abilities!
Fu Wei placed a soybean-sized blood crystal into the item compartment.
The [Extractor]'s electronic screen displayed the item's information:
[Energy crystal] [Elements contained: mixed crystals, energy factors, unknown microorganisms. Please select a substance to extract.]
"There really are living things in here! Otherwise, there's no explaining that flowing red light."
Fu Wei had confirmed his initial hypothesis. Energy did not come from nowhere; it had to be attached to some kind of substance. In this case, that substance was microorganisms!
"Well, damn! Are we going to use science to unravel the mystery of where zombies get their energy today?" Shen Jin knew nothing about biology, but that did nothing to stop him from sitting beside Fu Wei and enjoying the show.
"Hard to say. This extractor has a flaw. When it extracts one substance, it destroys all the others. Look."
Fu Wei pulled out a small drawer at the bottom of the [Extractor]. Inside were the remnants left after extracting the "tin" from cans, all reduced to powder.
"I'm afraid their molecular structures have been completely pulverized. There's no restoring their original composition."
Shen Jin nodded. "So we can only choose one substance to extract from this blood crystal, too. If you want to run experiments, you'll need a lot of blood crystals, right?"
Fu Wei nodded awkwardly. He knew these things only appeared inside the skulls of evolved zombies.
Their current supply was tiny!
"How about this? I'll give you two more for your experiments. Once we kill more mutated
