The best part about the Mighty Roar Flash Blast technique that he had gotten from G'ak'arkan Tribe, as well as the Sonic Bullet technique was that he could control the kind of damage that he inflicted on the ceiling of the dungeon.
Thus he could control the projectile to ensure that the resulting crater was ten meters wide.
He found it a shame that he couldn't use tier four Transverse Resonance, where he overlapped four sonic projectiles in constructive resonance. Unfortunately, that required a distance that was far in excess of ten meters.
THWOOM THWOOM!
BAM!
He kept striking at the ceiling, forming a deeper crater with each attack. The hot air pipe definitely helped, even if it wasn't too significant. The heat made sure that the damage was more localized whereas impacts could spread unscrupulously
The land around him shook with each attack, so he hoped that Kane was aware that he had already begun. He wasn't too sure, however, because esoteric ore deposits jammed all senses by inhibiting the flow of energy and matter. This included seismic radiation since even now he was unable to detect any external seismic radiation in the ground.
Rui made steady but slow progress. Ordinarily, this would have been a matter of several attacks at most had it been ordinary bedrock. However, the Shionel Dungeon was reinforced with dungeonified vegetation and low-grade Squire-level esoteric substances. This astronomically increased their durability and thus the force needed to fragment the bedrock.
THWOOM THWOOM!
BAM!
CRACK!
Rui narrowed his eyes as his senses heightened, a small trickle of water had begun dripping through the cracks in the crater. The cracks had crossed across the remaining bedrock left. The fact that they were made out of Squire-grade esoteric and reinforced by the dungeonified roots of the dungeon was probably the only reason that the remaining bit of bedrock had not been utterly shattered by the sheer weight of the entirety of the lake.
Rui gathered energy across his entire body as his muscles tightened.
His nerves tingled as he readied himself for what was about to come.
His body brimmed with power as he positioned his feet ready for running, before inhaling from his hot air pipe one more time.
THWOOM THWOOM!
BOOOOM!!!
A huge explosion of water blasted through the newly formed hole at a shocking speed. The water accelerated downward, pulled not just by gravity but also pushed down by the extreme weight of the entire lake pushing down on all of it.
The air rippled as the water blasted through, blasting downward with great speed.
Yet Rui didn't wait even the briefest moment to admire the sight. He immediately dashed away with Gale Force Breathing and Outer Convergence, running forward at top speed.
The sheer speed at which he ran blasted the air out of his way, leaving sonic booms in his way as he shattered the sound barrier.
With Riemannien Echo, he could sense that there was no shortage of monsters in the water that was rushing behind him, eager to catch and swallow him up!
He could even sense what seemed like a Megalodon Shark!
('Ain't no fucking way I'm dying in the jaws of that, hell no,') He picked up the pace as he strained himself even more.
He was almost there.
STEP
He leaped into the air as he sky-walked up a straight tunnel that led right up.
It wasn't that the water did not enter the vertical tunnel leading upwards either, but the pace was pitifully slow. Rui knew it was because the water had already begun traveling extensively through the convoluted maze of tunnels that was the Shionel Dungeon.
Many of those tunnels led to lower levels, and they would be the first to be flooded.
Rui considered the ramifications that this would have on the rest of the dungeon. The tunnels were actually quite small compared to the volume of water, which meant that the tunnels were most likely going to be filled to the brim.
The aquatic life that got swept away would not necessarily die immediately. They would instead live in tubes for a while until the water got absorbed into the bedrock of the dungeon and by the roots of the dungeon too.
The water would accumulate in places where the tunnels ended in a dead-end creating various pockets of water that could sustain some of the aquatic life.
Funnily enough, he didn't think most of the adventurers would be affected by this the way they were affected by the ants that were released from their dungeon just yet. The reason for this was that the water would get swept deep into the dungeon, places that hadn't been explored yet.
('Wait a minute, this will actually help us now that I think about it,') Rui noted.
The places of the dungeon where the water clogged indicated a dead-end. Thus Rui and Kane could safely avoid such segments of tunnels the moment they entered his Riemannian Echo.
It was only the tunnel systems that were empty that actually had paths forward.
('On top of that, this is an advantage that only Kane and I can enjoy because this water isn't sticking around forever!') Rui grinned.
This would significantly cut down on their exploring activities by highlighting all the paths that they ought not to explore. Gaining even more of an edge on Chairman Deacon was music to his ears.
('They're not even going to know what happened, hopefully,') Rui smirked. ('Not unless they find the nineteenth floor, but it will probably be too late by then.')
Even if they did happen to find the floor, he would have long gone having taken all the esoteric ore deposits from the floor.
('Right, I ought to get back. The lake will take some time to drain though.')
Even if the hole was ten meters wide, the lake was more than a kilometer in diameter. It was not going to get drained any moment now, they would probably get to watch how the aquatic life forms dealt with this new crisis.
