This was plausible reasoning.
If we notice the carriages that got attacked and which were unharmed - then there's something clearly out of proportion here.
Even though all carriages were destroyed, only the disciples in the third carriage lost their lives.
The disciples on the other two carriages were technically unharmed, except for the fact that one disciple was killed.
'They were definitely more focused on the third carriage.'
And which carriage was at third when the journey started?
The one in which Ye Tian Yun and Jun Xie were seated.
'Is this some indiscernible plot by Yuan Shuchun to take out both Shu Xian and Jun Xie?'
"Everyone, keep your steps lighter."
Yuan Shuchun suddenly whispered as she slowed down.
They were now getting closer to the target.
"Hm?" Suddenly Ye Tian Yun frowned.
He turned his head towards Jun Xie, who too was similarly frowning.
