After talking for a while, Shen Wan and Du Shen both had grave expressions. But Wen Nannan's heart secretly felt relieved.
According to the old professor's research, within the next day or two, the acidity of the acid rain would reach an extremely terrifying peak. Although as it was the last two days of the game, she could already assume as much. But the most important thing was that the old professor had revealed another piece of important information - that the research institute had a newly developed acid-proof room.
He told them the location of the safe room, hoping that they could plan ahead. However, the safe room had a limited number of spots. It could only fit about twelve or thirteen people at most.
"I'm already old , and I don't have many days left, but please help me take care of Shen Wan and Du Shen, and take them out of Rainy City," the old professor said, expressing his innermost thoughts, "As for the remaining two spots, leave them for the young people outside."
