A single deduction with his spiritual sense could not solve the actual problem. It had to be done repeatedly.
The deduction process was boring, but he could not afford to be careless.

If their current forces were not enough, they would send more troops. If their equipment was too poor, they would upgrade it in time.

It might take a few times, even dozens or hundreds of times.
After the deduction was successful, he could apply the result to reality and have a chance of winning.
Of course, winning in deduction didn't necessarily mean winning in actual combat. This was something that had to be made clear.
The use of spiritual will deduction was to exchange a higher chance of winning with a lower cost.
