Han Fei didn't expect that Xue Fei would become so strong when he had the ability to materialize the Vast Ocean Navigator. Ten million energy crystals in exchange for a Sky Opening Realm powerhouse was really a good bargain.
This meant that as long as he experienced a tide wave, with the harvest of the tide wave, he could kill a dozen Sky Opening Realm powerhouses. If Xue Fei had such means in the past, he wouldn't have been reduced to the lord of Mountain City.
Of course, a large part of the reason why Xue Fei was so strong today was that someone in the outside world had blown up these two people, and Zhang Li had suppressed and destroyed the other party's soul. Otherwise, if the other party was still conscious and could guard his soul, even if Xue Fei entered the other party's Origin Sea, he would only be suppressed by the other party. It was almost impossible to kill two emperors in a row in this short period of time.
