Winning was impossible.
Even if Xia Xi did not activate his War Mark or Supreme Territory.
The boost from Dawn Breathing alone was enough to crush all three of them effortlessly, even with them giving it their all.
In the end, the three children limped back to the research institute and ate the consolation meal Xia Xi had prepared for them.
Together with the highly rewarding combat experience.
This meant the Water Breathing lineage had not lost out by coming here to spar this time; they had even come out a little ahead.
These battles, which the Nine Hashira approached with a resolve to fight to the death.
Were highly beneficial to both sides.
After all, Xia Xi could also gain quite a bit of proficiency.
Unfortunately, once he activated all three overlapping territories in battle.
The difference in strength became far too great.
The experience gained after these sparring sessions would decrease rather than increase.
So the Dawn Hashira could only, between "crushing weak opponents at full power" and "holding back his strength"...
Feel out a balance that offered the best returns for his Breathing Style.
Overall, after a single sparring session.
Depending on the strength of the Nine Hashira's lineup, it could provide roughly 100-200 proficiency experience.
That might not have seemed like much.
But it actually equaled several days of dedicated training.
After all, when practicing his swordsmanship normally, Xia Xi could not devote all his time to training every day.
It was difficult to maintain the theoretical maximum experience gain over the long term.
But when none of the Nine Hashira had time.
Xia Xi could only keep grinding experience with the less rewarding [Threefold Territory] method.
And under this training.
As for the strength of some of the Provisional Hashira, apart from those recently promoted.
