After destroying the laser matrix, everyone stopped to take a brief rest.
Having previously swept through two demon laboratories, they had harvested fifteen regular Crystal Cores, three Skill Crystal Cores, and two portions of Source Material.
Su Muyu took out the two portions of Source Material and handed them to Lin Zeyu, asking, "We just obtained two portions of Source Material, both are Professional Source Material with specific properties. Do you want to use them?"
Lin Zeyu took them and examined them in his hands before asking, "Lu Heng, which one should I use? I need to return soon and pick one quickly, otherwise I won't be able to complete my first challenge task."
The first of the three challenge tasks was the Source Material Contest Task.
This challenge task was not mandatory to complete, but there was a reward of Divine Energy for completing it.
If it was possible to complete, of course, it was best to do so.
