Jake's brain was thinking fast, trying with all its might to explain how they had gotten to this point. Each of them had a fully functioning Oracle device to predict the ideal Path in this situation.
Even Lu Yan, who was at least Rank 4, had assured him a few weeks earlier that she and her brother had a plan for this arena fight. This meant that at that time the probability of failure was extremely low.
Jake doubted that Lu Yan would be able to sacrifice her brother to achieve her goal. He hadn't fully grasped her personality yet, but if there was one thing he was sure of it was the strength of the bond she shared with her brother, or her acting was more terrifying than he imagined.
In any case, Lu Yifeng couldn't have been deader than that, and his sister's wrath couldn't be more sincere. Whatever their original plan was, it had failed.
