Seiya - Backfire

I yell to Seiya, but Oxerio’s stomach suddenly bursts into flames with an ear-piercing explosion. And just like that, the massive robot comes crashing down.

“What the...?!”

As I watch in astonishment, Seiya calmly says:

“I sent a few earth serpents into the cannons before attacking the skull.”

“Wait. So that explosion was caused by the earth serpents?! You blew up his laser cannons?!”

“Yes. While I understand the desire to attack seamlessly, leaving the hatch on his  stomach  open  was  a  poor  move.  You  should  always  close  a  door  after opening it. By the way, whenever I go out and lock the door behind me, I turn the knob and pull thirty times to make sure it’s really locked before leaving.”
