With Sengoku leading the way, the remaining three quickly set foot on the island.
As for the others, it was very troublesome to transfer to smaller boats because the boats were difficult to dock.
Meanwhile, this might also involve Bai Yu's secrets, so Sengoku abandoned the idea of sending others to the island, leaving only an order to stay put.
A distance of two or three hundred meters, for Sengoku and others, would indeed significantly reduce their strength if they lost their Devil Fruit abilities.
However, with the Six Powers, they could still easily land on the island.
When you get close to that ancient tower standing on the isolated island, an inexplicable sense of oppression washes over you.
Everyone's heart clenched instantly.
Their intuition told them that this was no ordinary thing.
"As expected of Bai Yu's work, it is indeed extraordinary." Sengoku exclaimed sincerely.
This wasn't the first time they'd seen the strange things Bai Yu had taken out.
If, however, this strange feeling did not exist.
Sengoku, on the contrary, believed that Garp was setting them up.
"Hmph, do you really think I'd joke with you about something like this?" Garp snorted unhappily, but his actions were decisive as he strode to the closed tower door.
Bai Yu said that as long as we enter the tower, we will have the opportunity to gain new power.
" Ryokugyu, we'll need you to cover for us this time. You'll definitely get your share afterwards."
After the destruction of the Marine Headquarters, Ryokugyu could have chosen to stay out of it, return to being a hermit on the sea, and live a carefree life. Garp believed that the Five Elders would not pursue the matter.
Moreover, the fact that Devil Fruit powers have now been taken back is not limited to the Marine Headquarters.
Given the ambitions of the Five Elders, this kind of thing is bound to spread to the entire ocean, and even the world.
So Ryokugyu did lose his Devil Fruit powers, but despite the overall decline in global strength, his status on the seas hasn't diminished much.
"Hehe, Mr. Garp, Sengoku Fleet Admiral, you flatter me. I've only met Bai Yu two or three times, but I know him quite well. Great men don't concern themselves with trifles, do they?" Ryokugyu chuckled dryly and took a long-awaited swig of his drink.
Originally, having the Wood-Wood Fruit, he had already reached the level of fasting through photosynthesis, finding even eating and drinking troublesome.
Unfortunately, his divine aura has now been shattered, forcing him to fall back into the mortal realm.
Meanwhile, after the recent battle, seeing Bai Yu drink at the drop of a hat rekindled Ryokugyu's long-dormant thirst for alcohol, successfully leading him back to his drunken ways.
Sensing that Ryokugyu held no grudges, Sengoku secretly breathed a sigh of relief, then looked around and said.
"Alright everyone, are you ready? If so, let's go in."
"Heh, Fleet Admiral Sengoku, you're being too polite with all that talk," Kizaru chuckled dryly.
"However, Fleet Admiral Sengoku, you are a strategist. Do you think this place might be filled with Devil Fruit, or at the very least, all sorts of strange things to help us gain strength? If so, we could get our revenge very quickly."
As he spoke, Kizaru quickly stepped forward and pushed open the tightly closed door.
The moment the creaking sound rang out, everyone's nerves tensed instantly, and their eyes turned to follow the opening of the door, peering into the depths of the ancient tower.
It could be said that Kizaru's words seemed a bit unreliable.
However, it clearly expressed what everyone was thinking.
However, the ancient pagoda's doors were wide open, and all they could see was an empty space, which made them pause in surprise.
This scene was something even the title of a strategist from the Sengoku probably never expected.
However, before they could react, a clear, emotionless voice suddenly rang in their minds.
"A team member was detected attempting the 'One Punch Hard Dungeon. They currently have one attempt. If they fail, their attempt count will be reset to zero."
"At the same time, the deducted points will not be refunded, please be prepared."
A series of sounds rang out, and the moment they heard the words "Please get ready," Sengoku and the others thought they would be given a chance to catch their breath and figure out what was going on.
Unfortunately, before they could react, a tremendous pulling force burst forth from inside the ancient tower, forcibly pulling the four of them inside.
As the ancient tower's doors slammed shut, Sengoku and the others felt the world spinning around them. No matter how hard they tried to resist, it was to no avail.
By the time they came to their senses, everything had changed dramatically.
The four of them were standing on a high building, and as they looked out, a sense of unfamiliarity washed over them like a tidal wave.
The dilapidated streets and the sounds of traffic were completely out of place in their perception of the world.
The four of them were completely dumbfounded by what they saw.
Is this the same empty ancient tower they saw not long ago?
"War, Sengoku, if I don't slap you twice, and if it doesn't hurt, remember to tell me, then I'll know I'm dreaming," Garp said with difficulty.
Sengoku, who was standing to the side, snapped out of his daze and shouted angrily.
"Why won't you let me slap you? Bai Yu mentioned the situation of this ancient tower to you, but you fucking tell us..."
"If we come back empty-handed, we'll definitely pin you to the ground and slap you across the face."
Garp's imposing aura suddenly weakened, and he turned his head away guiltily, looking around.
"Ding-dong, congratulations to the four of you for successfully entering the One Punch Dungeon. The current mission is to slay the Dragon-Level monster, Vaccine Man."
"Upon successfully defeating the Dragon-Level monster Vaccine Man, you will have cleared the level and received one chance to open a blind box, the rewards of which are random."
Please complete the task within the specified time; the current time limit is twelve hours.
A series of system notifications sounded again.
Before the sound faded away, they didn't even have time to ask any further questions.
A scarlet countdown has already appeared in the sky.
Sengoku's expression changed slightly. He tried to ask again and again, but no matter what he said, the voice that had entered their minds without warning never reappeared.
Such a bizarre scene made Sengoku give up the idea of asking further questions. He glanced at the red countdown in the sky and then said...
"It seems this so-called instance world is different from our world. As for the completion time, it's twelve hours. Based on my deduction, if we can defeat the so-called Dragon-Level monster Vaccine Man within twelve hours, we will receive an unknown reward. This might be the power Bai Yu mentioned, and it's also one of the most perfect ways for us to leave this place."
"However, there is a second possibility: if we are unable to defeat the Dragon-Level monster Vaccine Man within twelve hours, we will also be expelled."
