Bo Yuting sat down beside Lin Wu and handed her the documents he had brought.
Lin Wu took them, puzzled, and opened them to find several identification results and a small piece of stone.
The contents of the paper can be left aside for now, but Lin Wu recognized the stone at a glance because it had a very unique fragrance, faint as it was, she would never forget it.
It was the stone from the mining tunnel that could isolate the toxic black mist!
Lin Wu looked at Bo Yuting in surprise.
The man softly explained, "I had some spare time these past few days, so I remembered this stone and used the Independent Alliance's laboratory to research it. Its texture is extremely hard; it took me quite an effort to successfully cut out a fragment for the experiment. And then I discovered that the components contained in this ore are no less than those in the black mist."
