Wei Shan understood Lin Yi's meaning and said, "They still need sunlight to be completely killed, it's laborious and unrewarding."
Mao Feiyang chuckled slyly, "Not necessarily... I have an idea."
Lin Yi quickly responded, "Let's hear it, see if it's handy enough; if it wastes time, then forget it."
Their main goal is to find the "Primordial Ash Apostle," no need to waste too much time on these little nocturnal species.
Mao Feiyang then said, "It shouldn't waste much time."
"How so?" Lin Yi asked.
Mao Feiyang grinned and said, "This needs you; if you slightly fold the Teaching Building's layers, you can let sunlight in."
"Look closely, this stairwell is like a milk tea cup, sunlight can only come in through the straw hole, but if we unfold it on the map level, we can let the sun shine on its inner walls."
