System Upgrade

"Shall we begin then?"

Son Goku said.

Son Gohan nodded.

Seeing this, Son Goku let out a loud shout and charged toward Son Gohan.

"Whoosh..."

"Swish..."

In an instant, Son Goku reached Son Gohan, his fists striking out like lightning, but Son Gohan dodged them all.

Son Goku gritted his teeth and threw his fists forward with all his might.

Son Gohan dodged to the side and drove his right knee hard into Son Goku's abdomen.

Son Goku let out a pained cry, a mouthful of saliva spraying from his lips.

At that moment, Son Gohan clenched his right fist tightly and landed a heavy blow on Son Goku's face.

Son Goku's body was sent flying backward instantly.

Son Goku clenched his hands into fists, quickly stabilized his body in mid-air, and wiped the graze on his face.

Immediately after, he gripped his hands tightly.

"Ha!"

With a loud shout, Son Goku transformed into a Super Saiyan.

"Whoosh..."

After transforming, Son Goku's figure flickered, and he arrived before Son Gohan in a flash, his fists striking out with force.

"Whoosh..."

Bang, bang, bang!!

Son Gohan raised his fists, and the two began to trade blows.

Violent gusts of wind soon erupted across the sky.

"Ha!"

After they had been fighting for a while, Son Goku suddenly let out a shout and kicked forward with his right leg at full power.

Son Gohan dodged to the side, grabbed Son Goku's right leg with his left hand, and flung him away, sending Son Goku's body spinning through the air.

"Ah!"

Son Goku cried out, quickly stabilizing his body in mid-air.

Just then, Son Gohan's figure suddenly appeared behind Son Goku, and with a flying kick, he sent Son Goku crashing down to the ground.

With a thunderous boom, a massive cloud of dust was kicked up from the earth.

"Whoosh..."

At that exact moment, a figure suddenly appeared behind Son Gohan, throwing a right fist forward with all his might.

That person was none other than Son Goku.

"Instant Transmission, is it!"

Trunks exclaimed in surprise.

"Whoosh..."

As the words left his lips, Son Goku's right fist passed straight through "Son Gohan's" body.

"Oh no!"

Son Goku seemed to realize something and quickly spun his body around.

Just then, Son Goku saw a small fist flying toward him.

Because the distance was so close, Son Goku was sent flying by the punch, crashing into the mountain behind him.

Seeing this, Piccolo couldn't help but frown.

He had originally wanted to spar with Son Gohan... but judging by the current situation, if he really fought Son Gohan, he would likely be taken out in a single second.

A while later, as the dust on the ground settled, Son Goku panted heavily and slowly climbed out of the mountain.

"Gohan, you are truly too strong now. Even after I transformed into a Super Saiyan, I'm no match for you!"

Son Gohan nodded.

"Dad, why don't you, Trunks, and Uncle Piccolo all come at me together?"

"Together? You mean the three of us should fight you at the same time?"

"Yes!"

Son Gohan nodded.

"Piccolo, Trunks!"

Son Goku looked toward the two of them.

"I have no problem with that!"

Trunks said with a serious expression.

"I don't have a problem either!"

Although Piccolo was not particularly keen on fighting Son Gohan, he certainly could not let Son Goku and the others know that he was intimidated.

"Alright then, the three of us will go together!"

"Mm!"

Trunks nodded.

With that said, the three of them surged up into the sky together.

Soon, the three of them arrived before Son Gohan and threw their fists forward with force.

"Whoosh..."

"Swish..."

Bang! Bang! Bang!!

Son Gohan dodged while simultaneously launching attacks at the three of them.

Bang!!

A moment later, Son Gohan clenched his right fist tightly and sent Piccolo flying with a single punch.

Seeing this, Trunks immediately transformed into a Super Saiyan to battle Son Gohan.

After a long while, Son Gohan defeated the three of them while in his base form.

This made the three of them fully realize the gap between themselves and Son Gohan.

Trunks: "Gohan, we lost!"

"It's alright, Trunks. As long as you keep training hard, you can become as strong as me in the future!"

"Mm!"

Trunks nodded.

In the blink of an eye, three days passed.

Today, just like any other day, Son Gohan was training with Trunks on Mount Paozu.

"Ding! System upgrade successful. The system has added a feature: Combat Power increases by walking!"

"Walking!"

"Yes, Master. This means that even if you are just walking, your Combat Power will increase!"

"Can it increase while I sleep?"

"...I'm afraid that won't work!"

"Then how much Combat Power do I gain from walking?"

"Under normal gravity, you gain 10 Combat Power per step. If you are in the 100x Gravity Chamber, you gain 100 Combat Power. If it is 500x, it is multiplied by five!"

"Can I run?"

"Of course! Running is also calculated based on your steps! Additionally, Master, if you perform a standard one-finger push-up now, your Combat Power will increase by 20!"

"20!"

"That is double the original amount. If you train under 800x gravity now, a single one-finger push-up would increase your Combat Power by approximately 1,600! If you do 10,000 of them, that would be 16 million!"

"16 million!"

"Yes, Master!"

"It looks like I'll have to ask Bulma to help upgrade the Gravity Chamber!"

"What's wrong, Gohan?"

Trunks asked, seeing Son Gohan freeze in place.

"It's nothing! I just suddenly felt that the gravity in this Gravity Chamber is too light and needs to be increased!"

"..."

Upon hearing this, Trunks was rendered speechless.

The 500x Gravity Chamber was indeed too light for Son Gohan, but... for him, it was unbearably heavy.

The next morning.

Son Gohan arrived at Bulma's house early in the morning to ask for her help in upgrading the Gravity Chamber.

After hearing his request, Bulma looked at him with a reluctant expression.

"Gohan, are you asking me to upgrade your Gravity Chamber again?"

"Yes! Please, Aunt Bulma, I'm begging you!"

Although Bulma was not particularly keen on upgrading the Gravity Chamber for Son Gohan, seeing him plead made it difficult for her to refuse, so she eventually agreed.

"Fine, but this time I'll boost the Gravity Chamber to eight hundred times gravity, and you are not allowed to come back to me for three years—no, make that five!"

"Deal, Aunt Bulma!"

Son Gohan laughed.

"Well then, hand over the Gravity Chamber."

Upon hearing this, Son Gohan immediately handed the Hoi-Poi Capsule containing the Gravity Chamber to Bulma.

"So, Aunt Bulma, how long will it take you to upgrade the Gravity Chamber to eight hundred times?"

"I'm not entirely sure, but I'll give you a call as soon as I'm finished!"

Son Gohan nodded.

"Then I'll leave it to you, Aunt Bulma!"

Bulma nodded in response.

Seeing this, Son Gohan immediately left Bulma's house.

Just then, a massive explosion suddenly erupted from the Gravity Chamber where Vegeta was training.

"That guy is at it again!"

Bulma looked toward the direction of Vegeta's Gravity Chamber with a sigh of resignation.

Ever since Vegeta learned about the Androids, he had been training in the Gravity Chamber like a madman, frequently causing significant explosions within the room.

There had been several occasions where Vegeta had nearly blown himself to pieces.
