Legendary Soul Art

"Alright, it is working better than I expected," Number One commented as he visited his Heavenly Space again. "I should be done in a few hours at this rate."

The light on the door advanced even further while the bottom of his bowl was filled with a golden liquid. It was the most Number One had ever seen so he made sure to savor it before he had to return to grind for more.

"I think I will go crazy if I keep shooting an empty space. Maybe it is time to test the Dungeon Mode," Number One muttered and finally returned back. He could tell the students were bored watching him beside one person that kept looking at him with a smile on her face.

Nami sat down in front of the glass and didn't stop staring for even a minute. Number One didn't know what happened with Miss Black but he knew for a fact that he wouldn't be getting contribution points from her.

'I guess I can only prove myself and scam Headmaster Blake for endangering my life,' Number One thought of a quick plan and called out confidently, "Activate Dungeon Mode, level 1."

[100 Soul Beasts Remaining]

The red sign lit up and a ten-second countdown started. Number One had no idea what kind of beasts were on the first floor of the Dungeon but he still ran to the corner as he waited for the timer to reach zero.

[90 Soul Beasts Remaining]

Ten flames lit up inside the room and they expanded into small green slimes. That was a surprise but Number One soon understood its unique ability. They immediately launched themselves at him by using their slippery slime and jumped from a distance with their arms trying to grab onto him.

Bang!

Number One fired his gun at the last moment and all ten slimes evaporated instantly. He wasn't worried about the first ten though but instead the next batch that began to spawn right away.

'One… Two…' Number One counted in his mind and his expression turned serious when the new slimes appeared. He was only at three seconds when the slimes launched another attack which forced him to adjust his plan.

Run!

Number One kicked the wall to bounce himself away from the corner. All slimes slammed against the wall while he rolled on the ground and ran to the opposite side until his Soul filled with new Soul Energy.

Bang!

Another bullet of light shot through the air and the slimes popped like balloons.

[70 Soul Beasts Remaining]

The counter went down again as new slimes spawned but they didn't learn from their predecessors. They rushed at him in a similar fashion and Number One dodged their attack once again. He was able to repeat the same strategy and kill one batch after another until the number hit zero.

[Level 1 completed. Time: 00:54.84]

"Too slow…" Number One commented with a disappointed sigh.

Number One could see himself in the low thirties but he was limited by his own Soul Energy. The only solution he could think of was either increasing the capacity of his Soul to at least 20,000 units or finding a way to increase the spawn rate.

The first option would be possible even on the same night if not for the fact that the golden liquid was slowly losing its effectiveness. It was able to give him an initial boost but Number One knew it wouldn't replace the standard cultivation. He would have to eventually find another method to advance further.

'I should be at twelve thousand right now so I can only think of the latter…' Number One wondered as he looked around the room and thought of an idea.

"Open menu."

"Spawn rate increase."

"I want to see the settings."

Number One tried multiple voice commands and a small console finally popped up after he mentioned settings. He approached the red panel on the nearby wall and sure enough, the spawn rate could be easily adjusted.

The ranking for the rooms could also be seen and he found his name in the middle of all the results. Even the multiplier bonus of the 50th room couldn't overcome the twenty seconds difference.

"Is he really increasing the Spawn Rate?" Headmaster Blake asked curiously as he watched Number One's prowess from the cafeteria. "Does he know that the slimes will stack?"

"I don't think he cares about that. He wants to kill them all in one go to set a record," Darius replied as he stood up for a better view. "He should be fine as long as he doesn't get greedy and set the maximum spawn ra—"

[Spawn Rate: Infinite.]

Darius ate his words as the new settings of the room displayed on the wall.

"I guess we might have to prepare to save him," Headmaster Blake informed. "He already suffered enough today."

Darius nodded as he watched Number One in awe. "He is already inside for more than an hour so his body should be on the verge of collapse anyway. No matter what kind of pill he used to heal his injuries, he is pushing himself too much."

Number One would only laugh if he heard Darius' comment as his body couldn't be better. It was his Soul that was more exhausted if anything. The constant refilling of Soul Energy was tiresome and even his regeneration couldn't help with that.

"Activate Dungeon Mode, level 1," Number One called out to start another run and the time started again. The second time was much different compared to the first.

[0 Soul Beasts remaining]

The number of beasts hit zero instantly and the whole room lit up with flames. The place was too small for all the slimes to spawn so they bumped into each other and formed into bigger blobs.

Number One expected them to launch at him right at the start but the opposite happened. The slimes ran away from him and jumped in a single spot in the middle of the room. By the time he realized what was going on, the Soul Beasts connected into a single organism before towering in front of him.

Bang!

Number One fired without hesitation but the massive slime extended its body to minimize its injuries and the large hole in its belly was quickly patched. The slime boss immediately covered all of his exits and smashed its body into the corner like a large ocean wave.

"Fuck."
