As soon as he enters, he was greeted by a brightly lit hallway with tall ceilings. There were thick cobwebs everywhere and the blocks of stone looks fragile. Even though Hisashi cannot feel normal things with his Ki, he can still feel the spaces and with his sharp senses, he knew that something is waiting for him here.
He looks at one of the stone blocks and takes a step on it. It sinks in and mechanical noises ensued. Rapidly, a bunch of arrows shoot out in his direction as he took a step back and dodged it. He, however, caught one of the arrows and inspects it.
"Not only are the arrows old and fragile, but the mechanism is also full-beat slow and weak in power. Anyone with decent skills can dodge it. It was good enough to work but bad enough to be useless." Hisashi said as he throw it to the ground along with the other arrows that didn't even pierce anything.
He continued to pave his way in the hallway stepping on the activation stones and he noticed something. Although many of the arrow traps still work, they were all not in their best condition. Some were worse than the first one, some were better, and some didn't even work.
For normal people, this premise seems like a good deal as that would mean an easy time. However, Hisashi was logical enough to believe the opposite of that.
"Those people that used to challenge this dungeon should be like that of a samurai. With their strength, it would be easy-peasy to dodge these traps even in their best condition. If they didn't come back, that would only mean that there's something more dangerous inside." Hisashi said to himself.
He contemplated first on whether he should continue or gather more info. But after thinking for a short while, he continued. The more he paved his way, the thicker the cobwebs were and after a while, he started seeing bone remains of some people. The smell also became different but that didn't stop him.
After walking for less than half an hour, Hisashi finally reached the end and what greets him is either a plantation or a graveyard. On the wider hall, there were a bunch of plant-like monsters scattered and hundreds of human skeletons with clothes, armor, and weapons on.
Looking at the plants, Hisashi felt like he finally knows the biggest predator inside of this dungeon. Although many of the plant monsters looked malnourished, a lot of them were also covered with cobwebs like the ones in the hallway.
"I refuse to blindly destroy nature, but you guys aren't normal plants," Hisashi said as he grabs his wooden training sword. His yoryoku then gathers on the sword as it turns into a fiery sword.
[Fire Sorcery: Shuchou no Yobigoe] (Call of the Vermillion Bird)
Although it seemed counterintuitive for a wooden sword to be set on fire, the sword wasn't burned even by a bit
"Let's try that move," Hisashi said under his breath as a dense wind yoryoku gathered on his foot.
"Flash." Hisashi suddenly reappears above one of the plant monsters as he struck it down effortlessly. The plant died like a flea as the fiery sword burned and nearly disintegrated it.
He continued to kill every single one of the plant monsters as he flashed his way through them. Suddenly, Hisashi had a thought.
'Can I use a different attribute to my flash? And I'm sure that it can be used along with a reinforcement spell. Well, trying it won't hurt.' Hisashi thought to himself as the wind yoryoku under his feet turned to lightning. He then tensed his muscle and he flashed meters away.
Hisashi succeeded and he felt a tingling sensation on his legs. Although the move looked the same, Hisashi saw the difference for himself.
"Using lightning is faster than the wind. However, the use of wind is smoother and enables me to do it at a faster interval. What about fire?" He asks himself as he did so too.
"Boom!" A small explosion resounded. Inside the dungeon.
"Wind enables smooth application and more frequent use increasing agility. Lightning is faster and quicker, but requires a higher interval which focuses on speed. And while Fire is a lot slower, it's heavier and more powerful focusing on power." Hisashi said as he laughs to himself.
"Rest in Peace to you Old Lady Yoshimitsu, but it looks like I'll be the one to fully utilize your technique. And I thank you for that." Hisashi smile at the thought of getting stronger.
For the next few minutes, he used the plant monsters as a practicing tool to let himself be accustomed to the differences and shift of changing the elements. He noticed how imperfect it was since he knows that the key element of it was the zetten, but he didn't mind it as he has no solution for it yet.
As soon as he finished every monster alive, Hisashi finally directs his attention to the large door at the other side of the room, probably leading to another room. He didn't waste any more time and pushed it open. With a space to come out from, a strong burst of wind brushes upon Hisashi, and an even larger room welcomes him.
This time, instead of a small fire, Hisashi conjures thousands of light balls. It slowly moves away from him as they look for a surface to stick onto. As they all managed to find their place, the room goes from dark to dimly lit room. With one snap, the intensity of the light increases lighting up the whole room.
Unlike the previous room, the current room is quite different given its irregular architecture. Along with the imperfectly shaped room, there are a lot of dark tunnel openings with some labels on the top. Sadly, the written language used isn't something that Hisashi knows.
"Where should I go to?" Hisashi said as he spreads out his Ki to every nook and cranny of the tunnels.
"This dungeon is a lot bigger than the one in Goshu. However, it also seems empty except for one. It would take me more than a day to comfortably explore this. With that in mind, I should let that last one with a faint presence be the last one to be explored. With such a faint presence, it cannot be a human and it must either be asleep, or weak. Either way, the room it is in must be the room for the core of the dungeon." Saying so, Hisashi chose a tunnel on the right.
Using more light balls, he lights up the tunnel the more he travels inside it. After walking for a couple of minutes, he finally saw the contents of the dungeon. On both his sides were prisons with steel bars - there were at least a hundred of them. Inside those are a couple of human remains that had a lot of dust and cobwebs covering them.
And finally, as he walked even more, he saw a last piece of evidence that made him sure of what the remaining entity is. A bunch of dried-up spider carcasses on the floor loitered around.
