Dragon Ball: I, Mr. Satan, am invincible!

"Oh! Hello."

Bulma's reaction was indifferent.

This was normal, as Mark was still wearing a martial arts uniform.

He was not handsome or elegant in appearance.

Bulma was always obsessed with looks, so such a reaction was normal.

The current princess vented all her grievances on Yamcha.

As bystanders, Krillin and Mark could only stand aside, watching the tea god's embarrassment with a gloating look on their faces.

Fortunately, the couple was still in the honeymoon period.

Bulma's anger was more of a complaint!

After complaining, the two of them were intimate with each other again, without any regard for Mark and Krillin's feelings.

After a while, Mrs. Brief came over with a coffee pot and invited everyone to have dinner together.

It is said that he has been locking himself in the studio for research recently.

Hearing that Bulma's friends were coming, he came out to take a breath and have dinner with everyone.

At the table, Mark saw the dinner of the world's capital family.

It was definitely rich and delicious, but that was all.

Compared with his own extravagant dinner, Bulma's dinner was really not worthy of the status of the world's capital.

During the dinner, Yamcha solemnly introduced Mark's situation to everyone.

After learning that Mark's strength was not weaker than that of Goku.

Bulma's impression of him changed.

Dr. Brief was not fascinated by these things in the world.

But he also sounded very interesting.

The topic at the table was naturally not too rigid.

After a while, Mark found an opportunity to talk to Dr. Brief.

"Doctor, can you design a gravity simulation device?"

"I want to entrust you to help me build a gravity training room, no matter how much it costs!"

Mark came to Xidu from afar for the purpose of the gravity training room.

This thing has appeared twice in the Dragon Ball world.

Their makers are all the unkempt Dr. Brief in front of him!

Seeing that the time was right, Mark directly stated his needs.

Of course, unlike Goku and Vegeta.

Mark, who was wealthy, did not need Dr. Brief to develop a gravity simulation device for him for free!

However, Dr. Brief did not care how much money Mark would give.

Instead, he asked with interest about Mark's demand for a gravity device.

"What? A 500-fold gravity simulation device?"

Mark estimated.

The limit of Vegeta's gravity training room is 300 times gravity.

Usually, he usually trains with 150 times.

When they were training on the Destroyer Star, the weight-bearing suits on their bodies made it difficult for them to move.

I think the weight must be more than 300 times.

In order to avoid trouble, Mark simply reported the requirement of 500 times.

In return, Dr. Brief exclaimed.

Picking up the cigarette again, Dr. Brief explained solemnly: "Mr. Mark, do you know what 500 times gravity means?"

"If you weigh 100 kilograms, 500 times is 50,000 kilograms, which means 50 tons of gravity are always pressing on you!"

"Not only muscles and bones will be under pressure, but also internal organs, blood vessels, and even every cell will be under heavy pressure."

"Not to mention humans, any carbon-based life may not be able to bear such pressure!"

"Haha, silicon-based life is almost the same!"

Dr. Brief's tone was very serious.

However, Mark understood what he said.

Seeing that Mark was unmoved, Dr. Brief could only talk about silicon-based life.

"Doctor, I will definitely not use 500 times gravity right away. It will only be one or two times at the beginning."

"As for 500 times, it is also for the future. In case I can adapt, I can save you from bothering you again!"

No alcohol was prepared for dinner, so Mark naturally did not talk drunkenly.

Seeing that Mark was determined to do so, Dr. Brief gave a positive answer and stopped persuading Mark.

After all, Dr. Brief is not a martial artist.

Although he still doubts whether humans can withstand such a heavy pressure.

But he did not deny Mark's needs.

Build a training room that can withstand 500 times the gravity.

All that is needed are high-pressure resistant materials.

This fee is very expensive.

Dr. Brief calculated the cost price for Mark, and the final price was 30 million Sony.

Mark blushed when he heard the offer.

In short, one word - poor!

After Mark bought luxury cars and luxury villas, the current liquid funds on hand are only more than 10 million Sony.

This was just confirmed by calling the assistant.

However, Dr. Brief saidAfter all, he is the richest man in the world.

Just say that you can pay 10 million first.

The rest of the balance can be paid slowly.

The doctor does not charge Mark interest, after all, he is a scientist, not a financier.

In this way, Mark can breathe a sigh of relief.

Mark is now the champion of the World Fighting Championship.

In the Satan City Martial Arts Arena, the deputy gym owner still gets dividends.

Even if he does not appear in the dojo for many years, the dividends that should be given to Mark every year will not be less.

If he loses a penny, Mark will have ten thousand reasons to kick Baka out!

At present, the martial arts arena can bring Mark a stable income of 10 million Sony a year.

After all, because of Mark, the ticket money for Satan City has been soft every night in the past six months!

It only takes two years to pay off the debt and improve his strength in advance.

Mark thinks it is still worth it!

In this way, Mark and Krillin lived in Bulma's house for the next ten days.

At the beginning of July, Bulma officially went on vacation, and the gravity training room that Mark had been thinking about was officially delivered to him.

It uses electric energy to drive, and the gravity can be adjusted from 1 to 500 times.

The area is about 400 square meters.

Considering the density problem, it can accommodate four people to practice together at the same time.

Of course, the premise is that the strength of the four people is not much different.

At least they can bear the same gravity.

This point was soon discovered to be inconvenient when Mark used it.

Mark's current strength can challenge 2 times gravity.

But Yamcha and Krillin can't. They are very tired training under 2 times gravity.

Finally, after Dr. Brief's adjustment.

The gravity training room was upgraded to adjustable regional gravity!

On the side where Mark is, the gravity is 2 times.

Krillin and Yamcha can bear 1.8 times and 1.5 times of gravity respectively!

In this way, everyone can improve rapidly in the best gravity environment.

Although, the system has been pretending to be dead.

But Mark's strength has improved rapidly!

In a blink of an eye, two years have passed!

May 6, 752 A.E.

In the courtyard of Bulma's family in the Western Capital.

Mark had a towel wrapped around his neck and a glass of juice in his hand.

He walked out of the gravity training room leisurely.

Picking up the combat power detector from the table in the courtyard, Mark directly tested his latest combat power.

This detector is one of the few rewards given to Mark by the system in recent years.

After starting, a string of numbers was directly displayed on the screen——

[Target combat power——2105! ]
