Xiaofan and Ren Ling were indeed unexpected products.
Each of them gained thirty years of power by borrowing external force, only Xiaofan's is more concentrated.
Therefore, the comprehension ability of the two is much faster than others. Of course, the required insight here also varies from person to person.
Three days after Ren Ling, Ren Ying also seemed to start getting familiar with that feeling, and Li San, who had sensed it on the first day, only managed to barely maintain inner peace to perceive it on the same day.
The strength of the Four Heroes of Yanhuang was also similar, and by the fifth day, they seemed to understand something. Among them, when Jie faced off Xiaofan for the first time against such a powerful Killing Qi, he almost tripped due to weak knees.
To be honest, the Four Heroes of Yanhuang had experienced countless harsh trainings and multiple life-and-death battles, yet at that moment, they could not suppress the oppressive feeling inside.
