Han Sen frowned, but he didn't have much of an opinion about Mister Ji breaking promises.
Mister Ji and Yisha's purposes were similar, so that did make them competitors. It was to be expected that they would fight and trick each other when co-operating.
The reason Han Sen frowned, however, was because of Yisha. He thought she had agreed too quickly to the idea of luring the Chaos there, and that she herself was planning to betray them. If they left now, they might lose an advantage.
While Han Sen was still in thought, a noise came from further into the oasis. From where they were hiding, they could see Yisha was running towards them with haste.
Yisha was incredibly fast, but she didn't look to be too concerned or rushed. Several arrows flew through the air right past her. It was a terrifying scene for Han Sen to watch.
Her abilities of movement were not inferior to Han Sen's own Dongxuan Movements.
