"Wait a minute. Is that why our armoury is filled with shit loads of different elemental shells?" Bu Dong brought up and it also dawned on Bin Yong that what the soldiers said must have a correlation to the damage dealt with the Ooofpa Loopa.
"This would also explain why the Southern Ooofpa Loopa in the seas has taken more damage compared to the one in the North. I saw them take lightning-based artillery shells to hit it, thinking that it might be more effective since it is submerged in the seas." Bin Yong reported as he picked up his phone to check the status of both Ooofpa Loopa to see how much of a hit point difference they had.
"Some of us theorised that the boss has entered a sort of invincible mode until we clear the Bone Spirit Hordes. So you're saying that's not the case?" Ruo Ying asked but the soldiers shook their heads.
