At dusk.
The yin and yang cards in front of Liu Yan and the other two had all been traded.
Apart from the yin and yang cards that they needed to leave the third floor, the rest had all been traded.
The gains they had obtained were enormous.
There were close to a billion federation coins.
Apart from that, there were countless rare minerals, herbs, and equipment.
The awakened ones who had successfully traded with Liu Yan were extremely happy.
Although they had paid for all kinds of precious resources, they had obtained yin cards or yang cards. They could successfully pass the trial on the third floor of the Tower and continue to live.
Liu Yan and the other two were also extremely happy. Yin and yang cards were practically useless to the three of them at the moment. They had all been exchanged for useful resources. It was undoubtedly a good deal.
