The heavy harpoons sailed through the air with the speed of bullets and a momentum that was far greater than that of bullets. Their fast speed through the air caused the air to shriek before the harpoons smashed into the airship with an even louder sound.
Unfortunately, despite all of that speed and power, the harpoons could only create dents on the hull of the airship. They couldn't penetrate the hull of the airship. Therefore, they couldn't be used to ground the airship.
This outcome was all because the airship's defenses had been improved by Greg. So Loki wasn't surprised by it.
However, as he probed the depth of the dent on the hull, he smacked his lips and said, "Who spends so much money on an airship? Now I am not so sure which is more expensive between the mech and the airship."
