If song qingxiao and No. 4's mission was to 'obtain the heart of purity', then I suspect that the other team's mission might be to' obtain the heart of darkness'.
In fact, regardless of the swordsman's previous request, the two of them would still have to go to the abyssal territory.
These Saints were related to the trial-takers 'missions and were important clues to obtain the heart of purity. Naturally, they could not be separated.
In that case, it was song qingxiao's job to agree to their request. Now, song qingxiao was just taking advantage of the situation to take the initiative in her hands.
Number four also understood this, but he just wanted to see if he could get something good out of these people. Who knew that the six Saints were so poor that magic and battle energy were not attractive to him. After hearing song qingxiao's words, he naturally nodded and did not say anything.
Time was of the essence, so the swordsman did not waste any time after he returned.
