A few moments before Arc faces Stoinis.
Arc went to the 17th floor from noon to night. His only goal was to gain more SP from the dungeon. He was successful to do that. Then he bought the Cancel Pain with 50,000 SP which was the most expensive of shop 3.
Cancel Pain grants Rimuru immunity to pain, giving him the ability to shrug off attacks. This is crucial in controlling the momentum of a fight and was used by Rimuru to full effect in his fight with Hinata Sakaguchi. During their fight, Hinata hit Rimuru multiple times with her sword, Dead End Rainbow, which attacks her opponent's spiritual body. Rimuru's ability allowed him to ignore that pain and keep fighting her to a stalemate.
However, there was a difference between Rimuru and him. Rimuru was a slime, if his body part was cut by someone, he could regenerate it. However, in the end, it will give him the courage to fight against a strong opponent. The setback of this ability is, he won't know if he is got hidden critical damage somewhere, because he won't feel any pain because it's a passive skill of his.
"Well, every good thing has a side effect."
Arc muttered.
"Shall we proceed to 17th-floor boss, Mira my dear?"
Arc told her.
"Ok, sir."
Arc then went to the boss's room. It was big fat cyclops. It was holding a huge hammer that jump in front of them while hitting the hammer on the ground. The most interesting part about this is, you don't have to be directly touched by it, even if you are 3 feet near it, you will get injured by the shockwave.
But he was easy to beat with Senbonzakura. Because except for jumping high, it wasn't that agile creature. So he easily won.
He didn't get any potion drop this time but two shards and a card.
"Wow, I got two Goku shards. I have 4 shards total now. Looks like to have Goku I have to dive 15-20 more and more."
Arc spoke. Though Miranda doesn't know what was he talking about, she remains quiet anyway because she believes that he was talking about some kind of power of his.
Arc then looked at the card. The name of this card is Plot Armor. Arc saw a description on it.
[You will get a plot armor card. This card will randomly choose an overpowering character according to who you are facing. Remember the same character may differ by their appearance and power scale depending on their enemy's weak or strong. This will save you from danger even if you can't kill them, or are too overpowering to you.]
Arc's eyes got shined after seeing this.
"It's a cool card."
Arc then touches the gacha card, and it then reveals the character of Plot Armor. It was Ichigo's Inner Hollow, Zangetsu, also known as White. (Manga Reference)
Description: It can go to the initial mask hollow to Vaste Lorde depending on your enemy's strength. Your enemy can be one or multiple, it will calculate the power and release according to that.
Arc was then interested in Vaste Lorde and thought if he could release that. They are extremely rare in number, and it is said that their entire number within Hueco Mundo can be counted with the fingers on one's hands. The combat capabilities of a Vasto Lorde are said to be above those of the captains of the Gotei 13.
Arc then shrugged and thought well, he is getting too cocky these days.
"Miranda let's go outside. No need to hurry. Opponents will wait for us by taking their sweet time."
He and Miranda then started to walk slowly toward the exit of the dungeon. And that's how presents appear.
The man who is from the organization Ambush took Stoinis from there.
"Miranda takes out the wheelchair, I do not want to stand up anymore."
He need mental rest because he was fighting from noon to night. Miranda took out the wheelchair from her adventure card, he then sat on it while putting his all weight on it.
Arc saw Isaac and several masked men came down in front of him. Seeing those masks man he wanted to scream, are you guys ANBU Black Ops? Though he controlled him.
"That power of yours, that may be high-class Domain, I never knew that you have that power."
Isaac asked him.
"No, this power is one-time power. It's not like I can use it all the time. However, I believe in the future, I will master it."
Arc told him with a smile. Then asked him,
"So, you guys were the one who was our backup."
Arc asked him.
"I was here, but only to observe your strength, I wasn't sent here to back you up, this five Royal Ninja was hiding to jump on the dire situation. They are one of the protector teams of the king, even the weakest one is stronger than the opponent you face just now, master."
Isaac told him.
"Well, that's a relief to hear."
Saying that, Arc close his eyes, and a few seconds later he got asleep.
