From the start of the battle to its complete end, it took less than a minute.
Seven Japanese Transcendents of no mean strength died at the hands of Li Changhe and Qiu Wentian.
Not knowing the details was their greatest, and most fatal, conceit.
They died from ignorance!
In fact, if those seven had been cautious enough to keep their distance and used shuriken or short bows for suppressive fire, and coordinated with what's called God Speed Iai, perhaps they could have caused a bit of trouble for Li Changhe and Qiu Wentian.
But they refused to believe that two teenagers, young in age, could possess a combat strength that looked down upon them.
They could not accept that years of hard training to hone their skills would be inferior to two little ghosts from Hua Country they had never heard of.
And then, they died.
