Ji Fanxin didn't hide it from Zhang Ruochen. She told him about going to the Yin and Yang Palace to find her senior sister.
That was her most important goal. Saving the other prides of the Thousand Pistil Field was the second goal.
Going into the Yin and Yang Palace to investigate is still very dangerous. If I go with someone as strong as Ji Fanxin, I'll be able to escape even if we're exposed. It'll be much better than going by myself.
Thus, Zhang Ruochen agreed to Ji Fanxin's conditions. They would cooperate temporarily and help each other.
Whoosh!
Zhang Ruochen's figure wavered and turned into a tall silver-haired man with a pair of dragon horns and a mask. His robe had been chosen carefully. It was a flying dragon saint robe.
Ji Fanxin, on the other hand, became extremely ugly and weak. Her skin was dark yellow and she also wore a mask. She followed closely behind Zhang Ruochen.
