Chapter 999: Drill Car

Inside the factory, they were avoiding the Sky Domination Clan people while scouting around. There was no need for Tang Yuge to check for them to know what these Sky Domination Clan people were doing.

As Lan Xuanyu had guessed, they weren't refining Space Source Crystals, but another metal that Tang Yuge had mentioned before, magic silver!

From previous metal detection, the magic silver on this planet was found together with Blue Coppertite. However, the accompanying ratio of magic silver wasn't even one percent. But this magic silver was extremely pure.

Those huge blast furnaces were constructed for the purpose of extracting magic silver from the Blue Coppertite. Although the extraction method was somewhat primitive, the temperature was impressively high.

After refining, the Blue Coppertite wasn't wasted but was made into enormous ingots of Blue Coppertite. Each looked to be at least five cubic meters in size, stacked in the corner.
