The last time this happened, it got censored, so I can only gloss over it.
"Th-this is Seimei's ability!"
"Yeah, the Young Duke took that hit head-on before!"
"Did the Young Duke take Seimei's power?"
"Wait, could he be the one who let Seimei out?"
"Is your brain broken? Can't you see that red light? If he really wanted to do that, he would've swallowed everyone inside already. There'd be no need to livestream it."
"He saved us, and people are still saying things like that? What an ungrateful bunch..."
"..."
He'd destroyed a warship with a single blow. Even though he'd used the same kind of power Seimei had displayed, it still sent shockwaves through the world.
This meant that most of humanity's weapons were probably useless against the Young Duke!
Once this red Ghost Domain spread, conventional weapons like cruise missiles were guaranteed to fail!
They still had nuclear weapons as a last resort, but they'd be no use if they couldn't hit him.
A one-man army!
"If the Young Duke wanted to, couldn't he just drain everyone aboard those warships?"
"Yeah. When Seimei's power covered them earlier, the survivors were already badly injured in no time."
"He was already holding back..."
"..."
The sailors aboard the American warships didn't need the livestream chat to remind them. After seeing their flagship sink, they didn't hold out for long before raising white flags.
A surrender announcement was also broadcast over the public radio channel, declaring that they were laying down their weapons.
Some ships were even afraid Tao Yu wouldn't stop, so their crews fled to the lifeboats and scuttled their vessels by opening the sea valves.
When Tao Yu's Ghost Domain spread, the American troops had already seen the reports about it, and their morale had plummeted.
