Oliver, Baki, and Naruto followed Revy to her gang's main base; it is an underground base.
When they entered the base, Oliver saw the base contained a couple of sofas, a blackboard, and all kinds of weapons like firearms, swords, sabers, axes, and many more hanging on the walls.
Oliver also saw computers, screens, and transponder snails on top of the tables and desks.
The base has a small kitchen, a shared toilet, a bathroom, and six private rooms.
Oliver, Baki, and Naruto sat on one of the sofas, and Revy followed suit after she served them some bottles of booze.
Oliver opened one of the booze bottles, and he started gulping the booze without any restraint.
"GULP, GULP, GULP."
"Sigh, this hit the spot; this is good booze, thanks, Revy," Oliver said to Revy while smiling at her.
Revy smirked when she heard the compliment, and she said to Oliver, "Good, this is my own special booze. If you had said otherwise, I would have turned you into Swiss cheese."
All of them then started laughing after hearing what Revy said to Oliver
Suddenly, the door of the base slammed open, and Rock entered the base.
Rock was bleeding profusely. His right arm was missing, his torso was filled with bullets, and he was on the verge of death.
When Revy saw Rock's current condition, she was shocked. She quickly got up and ran to him, then she yelled at him in worry, "Rock, talk to me; are you alright? What the hell happened to you? Who did this to you?"
"COUGH, COUGH."
Rock started coughing blood from his mouth, and he said to Revy, "Listen, Revy, I don't have much time. I figured out what is going on in our kingdom and where Dutch, Benny, and the rest of the people who went missing are."
When Revy heard this, her eyes widened, and Oliver turned to Naruto, and he said to him seriously, "Naruto, toss the bag to me."
After hearing Oliver's order, Naruto tossed the bag to him without any hesitation, and after grabbing the bag, Oliver walked to Revy and Rock.
He then said to Rock, "Listen to me, Rock. I might have a chance to save your life, but this depends on your luck."
Revy and Rock were surprised when they heard this, and Revy asked Oliver with an anxious tone, "Is this true?"
Oliver nodded his head and started explaining to Revy and Rock, "As I said, it all depends on Rock's luck. I and my crew obtained some devil fruits while we traveled here. If my guess is correct, three of these devil fruits are Zoan-type devil fruits. According to my father, the Zoan-type devil fruit users had incredible vitalities. If Rock eats one of these devil fruits, he might survive, but remember I am only guessing that these devil fruits are Zoan-type devil fruits; it all depends on Rock's good fortune."
Revy became emotional when she heard this, and Rock looked at Oliver resolutely and said to him, "I am willing to take the risk."
Oliver smirked when he heard this, and when he was about to open the bag and take out the devil fruits, he heard the system notification in his head.
The system detected that the host needs make a choice
Feed Rock a devil fruit and save his life; reward +200 IQ.
Don't feed a devil fruit to Rock and don't save his life; reward volume 1 of medical book collections written by doctor Hogback.
Oliver sighed in disappointment after hearing the system's notification and thought to himself, "My crew needs some medical expertise, but I need to save this guy so I can help Revy save her friends."
After making up his mind, Oliver took out three devil fruits from the bag and showed them to Rock and Revy.
Rock grabbed a random devil fruit before Oliver had a chance to tell Rock what kind of devil fruit it was, and Rock swallowed the fruit without chewing it, which stunned all those present.
The next moment Rock started coughing, then his body started growing up, and black fur started covering his body along with fangs and claws. Rock then transformed fully into a black bear.
Baki, Naruto, and Revy widened their eyes upon seeing Rock's transformation, then Baki said to Oliver, "Oliver, you were right; these three devil fruits belonged to the Zhang Kingdom soldiers that we defeated when we rescued Naruto."
Oliver smiled and nodded his head to Baki; they then started treating Rock's injuries.
After they finished treating all of Rock's injuries, Oliver then taught Rock how to transform back to his human form.
After Rock transformed back to his human form, Oliver heard the system's notification in his head again.
Congratulations, host. You saved Rock's life and fed him a devil fruit. Do you want to claim your reward now?
"Yes, I want to claim my reward now system." Oliver replied to the system.
Suddenly Oliver felt a warm sensation in his mind; he couldn't help but close his eyes.
After a few seconds, Oliver heard the system notification in his head again.
Congratulations, host, your IQ increased above 200.
Rock looked at Oliver with eyes full of gratitude and said to him, "Thank you for saving me. I owe you my life."
Oliver smiled when he heard this; he was feeling good for saving Rock's life.
Revy also looked at Oliver with gratitude.
Oliver nodded his head to Rock and said to him, "No worries now; tell us what's going on here. I promise Revy that I will help her save her friends."
Rock nodded in understanding, and he started explaining the situation: "On the east side of the kingdom, there is a small island called Purple Peak Island. Around one of the rocky mountains of that island, the royal family discovered the purple cold metal mines in very large quantities."
When Oliver heard this he was shocked and said, "Purple cold metal? Are you sure? This is a very rare material."
Baki, Revy, and Naruto looked at Oliver in confusion, then Baki asked him, "Is this purple cold metal that impressive, Oliver?"
Oliver took a deep breath to calm down. He then started explaining the purple cold metal to Baki: "The purple cold metal is considered a treasure to any blacksmith if a blacksmith uses purple cold metal as one of the materials when forging weapons. The weapon's quality will increase by a couple of levels."
Baki, Revy, and Naruto widened their eyes when they heard the news, and Rock looked at Oliver in a new light; he then nodded his head and said to Oliver, "You are right, but there is one thing that you don't know about purple cold metal: the purple cold metal is very poisonous by nature; it shortens the life span of those who touch the metal barehanded."
Oliver widened his eyes when he heard this, along with Revy, Naruto, and Baki.
Rock then took a deep breath and continued, "A couple of months ago, two pirate crews came here from the Grand Line. They murdered the king and imprisoned the royal family and the royal guards. Their crews then started kidnapping civilians along with kidnapping our friends; they forced them to mine the purple cold metal. Many of those who mined the purple cold metal died because their life span had been shortened from the poison that the purple cold metal contains."
Revy's eyes turned red when she heard this; she grabbed her bag and started walking towards the door.
When Rock saw this, he yelled at Revy, "Stop, Revy! If you go after them, you will die."
Revy was fuming in anger when she heard this, and she yelled back at Rock, "I refuse to sit here and do nothing. Benny and Dutch need my help."
Rock calmed himself down and said to Revy, "I am not abandoning them, Revy. We need allies and a plan. These two pirate crews are the Berserker pirates and the Magician pirates. I couldn't gather all the information on them because I was attacked, but I know their captains are devil fruit wielders. The captain of the Berserker pirates ate the Muscle Muscle fruit; he can crush us with only his fingers, and the Magician pirates captain is the wielder of the Ball Ball fruit; he can create any kind of ball with his devil fruit powers, like an explosive ball, a metal ball, you name it."
Revy, Oliver, Naruto, and Baki raised their eyebrows when they heard this, and Rock continued, "I almost died not from fighting those two captains but from fighting their crewmates. They are really strong, Revy; we need allies in order for us to have a chance against them."
Oliver smirked in excitement when he heard this and asked, "So, Rock, where are those two pirate crews stationed now?"
Rock was confused when he heard this question, but he answered Oliver, "According to my investigation, the Berserker pirate crew is stationed at Purple Peak Island; they are keeping watch on those they have kidnapped, and the Magician pirates are in the royal palace, keeping watch on the prisoners and the royal family."
Oliver nodded his head in understanding, and then he said to Revy, "Alright, we will go to Purple Peak Island first to deal with the Berserker pirates, free those they kidnapped, and then go to take care of the Magician pirates."
Rock was shocked when he heard this, but Revy, Baki, and Naruto smirked in excitement when they heard this.
"Are you insane? Didn't you hear what I just said?" Rock yelled at Oliver.
Oliver chuckled when he heard this, and he said to Rock, "Relax, Rock. First of all, you said that we need allies. If we save those who got kidnapped by the pirates, they will become our allies, and they will want revenge against the pirates after what they have gone through."
Rock calmed down thinking about what Oliver just said, then Oliver continued, "After we dealt with the Berserker pirates, we will charge towards the royal palace and deal with the Magician pirates. It is a good opportunity for Naruto to grow stronger and gain combat experience."
Baki's eyes widened in surprise when he heard this, and he asked Oliver, "Oliver, Naruto still needs more training; he isn't ready yet."
Oliver looked sharply at Baki and said to him, "This is the life that Naruto chose for himself, Baki. If he wants to grow stronger, he needs to fight those who are stronger than him and experience life and death battles."
Baki got quiet after hearing this, and then Naruto said resolutely to Oliver. "I will fight, Captain."
Oliver smiled after he heard the resolute tone from Naruto.
Revy then said to Oliver, "Stop wasting time, Oliver. Let's go to Purple Peak Island. I need to save Benny and Dutch."
Oliver nodded and said to everyone, "Alright, let's head back to the ship now and sail to Purple Peak Island."
Oliver and the others then exited the base and walked towards the ship to sail to the Purple Peak Island.
