<Hearing your words reminded the dead Piccolo of the hyperbolic time chamber. He immediately asked King Kai to connect to Gohan.>

<Gohan then received the news about the hyperbolic time chamber from Piccolo. It shocked him as it was precisely what he needed time to train.>

<Due to constant attacks by the Android, Gohan was forced to continuously go from one place to another to fight the androids and safe people. It really took a toll on his training.>

<He rarely got the chance to adequately train. He informed you and Bulma about this communication from Piccolo.>

John - "Should I ask if I can go in? Trunks is only seven, so maybe I could argue that he won't be able to handle the harsh conditions. Plus, I could occasionally train under Gohan."

<You make up your mind and ask Gohan if you can come. At first, he's not so sure, but after confirming that two people can practice together.>

<He agrees, provided that you won't disturb his training, to which you immediately agree.>

<The next day, you take sufficiently rich supplies and enter the hyperbolic time chamber. Gohan is easily able to move around while you are stuck at the entrance and barely able to move around.>

John - "Damn, I didn't think this through. I came barely move around under this intense gravity. This is worse than the hyperbolic chamber in dragon block c."

John asked, "System is there any way to, you know, cheese this so that the gravity slowly applies on me or something."

System spoke, "You could have asked me for a gravity ring, but no, you had to go and jump in the hyperbolic time chamber with your misly power level of 8. If you were to take even a step further, you would like legit die."

John - "Alright, I get it. Sometimes my brain doesn't work. Now sell your overpriced solution, will you."

The system replied, "Fine, you can purchase the gravity negating ring. It allows you to negate gravity completely. Just set it to 2, and you can train at two times gravity."

John - "So the difference between gravity ring and this is? That this does the opposite?"

System - "Correct, but the biggest difference is that gravity ring is much more useful as it can be upgraded continuously to increase its gravity."

John - "So these rings are not just for simulated characters, right? Cause if so, then I will have to repurchase every time a simulation ends, which would be too much."

System - "I am an upright principled system, not some scam merchant. Of course, you can keep the ring and use it on yourself in reality and on every character you simulate."

Hearing the system that scammed him of 56 fate points just a few moments ago call itself an upright and principled system, John felt his blood pressure rising like tidal waves.

John relaxed his nerved and asked, "How much do both these rings cost?."

System answered, "The gravity negation ring cost 40 points as it has minimal uses. While the gravity ring depends on what upgrades you want."

"For example, the ring costs 1,000 points and comes with 1 to 10 times gravity, 10 to 20 cost 200 points to upgrade, 20 to 30 cost 400."

"It has the increment of doubling the points of the previous upgrade. This goes on until you reach 100 times the earth's gravity. After which, the 100 to 200 series starts, it has a different price configuration ratio."

John heard so many numbers at once and felt dizzy. One thousand fate points was a number he didn't even know when he would touch. Not to mention these expensive upgrades.

John calmed his roller-coaster of emotions and bought the gravity negation ring.

<You automatically wore the gravity negation ring and turned down the gravity to 2. It allowed you, who almost froze, to break this ice and finally move your body.>

<Seeing you move, Gohan, who was a bit worried after looking at you frozen, was freed from guilt.>

<Originally, he didn't ask Piccolo if a human with a low power level could enter or not. As Piccolo didn't warn him, he thought you would be fine.>

John read this and said, "Jesus, that heartless bastard Piccolo wanted to use my death to help motivate Gohan."

"Luckily, I have a system and managed to lower the gravity. Otherwise, it really would be game over."

<Day 50: It has been three days since entering the time chamber with Gohan. You are still barely able to adapt to twice the gravity.>

<The good news is that your combat power is improving by withstanding this gravity. Your power level is finally in double digits at 14.>

<Day 57: It has been ten days since you entered. Gohan has gone so far out that you only see him when he returns for food.>

<Combat power has reached 28, and you are steadily getting used to the new gravity.>

<Day 67: It's been twenty full days in here. You have now fully adapted to twice the gravity and have started training.>

<Your power level has reached 50.>

<Day 97: Under Gohan's guidance and training in three times gravity, your combat power has skyrocketed to 270. It has now been a full 50 days.>

<Day 147: It has been one hundred days since you entered the hyperbolic time chamber. You are currently training under five times gravity and have a power level of 600.>

<You now understand why even a talented man like Killin was left behind in the dragon ball universe. As improving as a human is really hard.>

<Day 247: You have spent two hundred days here and can now handle training in seven times the gravity. Your combat power has far surpassed your last life and is at 1,750.>

<You have also mastered many techniques such as flying, Ki blast, Kamehameha, hiding Ki, Ki sensing, after image technique, and many more.>

John saw the combat power and didn't know what to say like always. His talent limited his achievements.

<Day 417: It has finally been a year in the time chamber, and you have reached eight times gravity. Your power level is at 4,647.>

<Gohan comes to you and informs you that both of you will exit the chamber today.>

<You ask Gohan how confident he is in beating the androids. He tells you he can't say for sure but thinks he stands a good chance of winning.>

John, "Nah, we don't do no probable stuff regarding my life. System, can you make it, so I see a list of power levels."

"Like they improve in real-time, and I just have to say their name for their power level to appear in my mind."

System - "That some crazy OP technique you want there. I don't have it, but I can make it custom for you. As this is your first custom request, the two zeros at the end will be removed."

John - "What two zero's removed? How much does it cost?."

System - "It costs 2000 points to design this technique, but now you have to pay just 20 points."

John - "Fine, do it."

System - "Done."

John then looked at the list and learned that Android 18 power level was at 245 million, Imperfect Cell was at 252 million, and Android 17 was at 256 million. While Gohan's base was at 5 million.

(Ps - These are not the author's power levels but were taken from particular YouTube videos. If you have opinions on it. I could only argue that Trunks is only seven, which is ten years before he kills Frieza.)
