Han Xiao had a rough idea as to what the fourth requirement was. Extracting again was impossible given the 0.3% success rate; neither Feidin nor Chen Xing would be willing to take the risk. Therefore, the only path left would be for them to reconcile. The extent of 'reconciliation' for the fourth requirement would definitely be more perfect than the third requirement, so it would require more time. Of course, Han Xiao preferred the fourth requirement with the greatest reward, but even if not for the reward, letting Feidin walk the same path as the previous life was beneficial for Han Xiao.
