There is no big difference between robbing the bones of sacrifices and digging up someone's ancestral grave. It is impossible without risking one's life.

But after the Allied Forces fought, many priests died on the battlefield, allowing Li Ziyu to harvest enough sacrificial bones, not to mention 100 units, even if they were turned over again, it would be enough.

Blood crystals condensed from the essence and blood of powerful warriors. This is a good thing. For many races that rely on blood cultivation to become stronger, it is like a panacea, just like the undead soul fire for demonized creatures. Li Ziyu curiously took it out and looked at it.

Look, they are ruby-like crystals the size of coins, showing irregular and multiple deformations.

Li Ziyu got tens of thousands of blood crystals this time. He felt that the value of this thing should be very high, especially for a race like vampires. He should keep it and exchange it with the vampire lord for some useful resources in the future.

For the skeletal undead tribe, the value of blood crystals is really not high. After all, it is a pile of bones. Not to mention blood, you can't even find a shred of meat on them. What use are blood crystals to the undead?

There are only two resources left, soul crystal and death breath crystal, which sound related to the undead. They are not included in the trophies. Li Ziyu has never seen these two resources before and has no idea what they look like.

I often heard about soul crystals in games in my previous life, but this is reality. Where can I get crystal mines?

Not to mention the soul crystal, even if it is a crystal, I have never seen it since I came to the other world.

The upgrade of the Fortress of the Undead was blocked by resources, which made Li Ziyu a little anxious, frowning, and looking unhappy.

"Master, what's wrong with you? If you have anything to worry about, you can talk to Mei Ji." When Mei Ji saw Li Ziyu's appearance, she floated over and floated next to him and said softly, with a sense of comfort in her voice.

As a ghost and a fox girl, Mei Ji's mental power is very strong. Under her comfort, Li Ziyu's brows slowly opened and she took a long breath.

"I need two materials, but I haven't seen them before and I don't know where they are." Li Ziyu said softly.

The four fox concubines are as beautiful as flowers, with different postures, fat and thin, but unfortunately they are all ghosts. When you get close, you can see that their bodies are as cold as ice, which makes Li Ziyu very calm and dare not make any other moves.
