The reason he planned to go to the battlefield was because he wanted to rely on the Kill Points to increase his cultivation as rapidly as he could to increase his chances of survival in this demon invasion, and also to take revenge against the Count Wiley, the Dalton and Royal family who forced Ashton to use that sacrificial method to save his family.
So, when the system went dormant, he didn't know what to do.
The only reason he continued the journey to the Royal capital instead of returning to the Ninam city was because he hoped to refine his fighting skills on the battlefield and let Emily and others do the same.

An hour before healing Sophie…
