Normally, a war between different worlds was fairly impossible. Especially if the two sides were too far from each other. But if the worlds involved were Sage Worlds, it's not impossible.
That's why, upon showing my Level 3 Earth Energy before threatening them with war because of their unauthorized invasion of this Mortal World, they fell into a dilemma.
According to the scar-faced Transcendent, they're just a detached fleet from Samsara's exploration troops. If they became the trigger of a war between two Sage Worlds, their lives wouldn't be enough to pay for their upcoming loss.
Well, it's a bluff on my part and I was fairly confident that they would bite it.
I was the proof of my Sage World's existence and its connection to this world. Entering this world stealthily allowed me to fool them that I came from a Portal.
