At this moment, Gu Si and Gu Wanru felt very regretful and wondered why they didn't prepare cash.

They should have thought of this when they saw Boss Song and those people writing IOUs those days.

I didn't expect that Bai Zimu got there first.

…

"By the way, Boss Song, this is a gift from my brother and I."

Gu Wanru took out a small box from her coat pocket.

It was carefully opened in front of Song Zhi, and four crystal cores of different colors lay neatly inside.

"Crystal core?" This surprised Song Zhi a little.

Can hard currency like crystal cores, which can be sold at sky-high prices in the apocalypse, actually be given away?

And you get four for free!

"Yes, they are crystal cores, but they are all first-level crystal cores. Please don't be disgusted, Boss Song."

Gu Wanru saw Song Zhi's shocked expression and explained.

"To be honest, when Boss Song took action, my brother and I didn't see what his special ability was, so we don't know what kind of crystal core would be useful to him."

The two of them obtained a number of crystal cores during their mission. Excluding those they absorbed, the only ones left were these four with different properties, which were just right for Song Zhi.

"My special ability... um..." Could she say that these crystal cores were useless to her except for being exchanged for wealth points?

"Okay, I'll take it. Thank you. If you need help in the future, you can come to me."

Song Zhi put away the crystal core.

If someone gives you something, it’s not good to refuse it directly, so just keep it.

"Crystal core? Oh, and where's the crystal core left behind by the third-level zombie you killed? We got it during the mission, so it should belong to our base!"

A sharp and somewhat anxious female voice came from the other side, attracting the attention of everyone present.
