No matter what, as Lu Yuanming had verified part of the information Tang Zhe'an had told him, he was certain that he really couldn't get help from Tang Zhe'an in the material world; even the news from America indicated that Alfred and the others had all perished as well.
It wasn't just Tang Zhe'an who had disappeared, but also the Dark Matter that should have been first discovered at Xiao Rizi's location, which was even more bizarre. If the lack of Tang Zhe'an and Alfred in this timeline could be attributed to the exposure caused by his traveling between two timelines, then shouldn't the Dark Matter at Xiao Rizi's still be there?
But it had also vanished.
As to why exactly this had happened, Lu Yuanming didn't know. He could only plan to ask Tang Zhe'an the next time he went back to the Dark Matter World.
