Luo'er didn't intend to speak up for Princess Melia. The matter was on their minds too. Although those cannons had been seized by the rebels, and the recent news was that the rebels had destroyed all the cannons. Still, they hoped to figure out where those cannons came from, and who exactly managed to export such weapons to Otherworld without the UN Security Council's knowledge.
If these cannons were not exported from Earth, then which nation had the capability to produce them? This is a grave issue. Considering that Earth's nations barely have an upper hand over the magic of Otherworld, if their specialty was learned by the Otherworld, it would be a significant issue. If one day, the armies from the Otherworld launch fully-armed attacks on Earth with powerful firearms and cannons, Earth nations will suffer a heavy blow to their pride.
