Chapter 180: Re-entering the Red Lotus Demon Cave Instance, Gathering Alien Metal Minerals (5k)_3

Su Xing slowly approached the rock and extended his hand to touch it. After a moment, he frowned slightly and said,

"This alien metal is actually mixed with other minerals... Doesn't that mean it needs to be refined before it turns into pure alien metal?"

Su Xing secretly thought he had miscalculated.

In this huge rock, which was a few meters tall, the proportion of the red alien metal was probably only three to five percent.

If he wanted to purify it into alien metal, who knew how much time it would take...

Su Xing was somewhat disappointed. The alien metal ore needed to be refined and purified to be completely obtained.

And profession users below the Heavenly King Level were unable to enter the depths of this demonic cave, where it was impossible to refine and purify alien metal.

The situation... seemed to have reached an impasse.

"Wait... who said it needs to be purified before it can be converted into simulated energy?"

Su Xing suddenly realized.
