Chương 1618: Memory-Consuming Eight Tunes Box

The shining rainbow crystal box was intricately made, and there was a fairy engraved on it.

The fairy seemed to be harvesting something while howling. It was as though there was something within her body that was trying to get out.

It could be said that the image engraved on the crystal box was peculiar.

However, Lin Yuan was not the most curious about the image carved on the crystal box but the rainbow light.

This light was very similar to that of an uncontracted sacred source lifeform.

Gao Feng noticed Lin Yuan observing his sacred source lifeform and said, "Lin Yuan, Master was willing to use his sacred source lifeform's roots to evolve this thing to 6 Stars. I have no idea what's going through his mind! How many of the young experts from the Freedom Federation that we'll be facing even have a sacred source lifeform?"

Lin Yuan was shocked when he heard what Gao Feng said.
