Liu Yan followed Luo Qingcheng and wandered around the black market where the Wanderers gathered in Riversouth Region.
Luo Qingcheng knew many people here. By using her powerful connections, they could sell yin and yang cards through the small vendors.
Luo Qingcheng was more cautious. A small vendor would normally only sell three to five yin and yang cards and would never sell more. This was the safest way.
When it was dusk, Liu Yan and Luo Qingcheng came out of the black market.
The originally hundreds of yin and yang cards had all been sold.
But after selling those yin and yang cards, they did not attract anyone's attention.
Luo Qingcheng had impressive ability to finish this job. She did not need Liu Yan's help at all.
Liu Yan looked at the terrifying amount of money in his bank card, but his expression was relatively calm.
They sold over a hundred yin and yang cards. They had earned more than one billion federation coins.
