I, Uchiha Hikaru, have joined the chat group.

Chapter 215 Two Things

Calculate the time.

Tanjiro has been in the Dragon Ball world for almost two months now.

Compared to when he first arrived, he seemed to have grown a little taller, and his reddish-brown hair had grown considerably longer. The most striking change was that his entire aura had subtly transformed, giving the impression of a complete metamorphosis.

When Uchiha Hikaru arrived at Korin Tower, he was meditating cross-legged in a corner at the top of the tower.

The cat sage was eating dried fish not far away.

"Oh, Ms. Hikari, you're here?"

"It's Hikaru."

"Master, Tanjiro."

Uchiha Hikaru greeted the two of them in turn, exchanged a few words of greeting, and then looked at Tanjiro's forehead, his eyes slightly narrowed:

"So, the 'spots' have finally awakened?"

That's right.

The dark red scar on the left side of Tanjiro's forehead has now turned into a mark, clearly visible like a flame.

opposite.

Tanjiro scratched his head and explained, "Well, after you asked me about the 'spots' last time, not long after, I activated them while I was stealing the 'Super Holy Water'... Master Cat has already checked them and confirmed that there are no problems, so I didn't tell you or Bulma."

"Oh?"

Uchiha Hikaru raised an eyebrow.

One of the basic conditions for activating "stripes" is indeed that the body is in an overloaded state after intense battles or training.

According to Muichiro Tokito, the Mist Hashira, in the original work, it means "a body temperature of 39 degrees Celsius and a heart rate of over 200 beats per minute." For Tanjiro, who already possessed this aptitude, it's not surprising that he acquired this ability after high-intensity training.

Can……

Are you sure this thing won't affect your lifespan?

It's important to know that, apart from Yoriichi Tsugikuni who was born with the Demon Slayer Mark, none of the other Demon Slayers who awakened their marks lived past the age of 25. Gyomei Himejima, the Stone Pillar, was an exception, awakening his mark at the age of 27 when he participated in the final battle. However, judging from what Muzan said at the time, he might not have many days left to live.

If it weren't for this drawback, Kokushibo, Yoriichi's older brother, wouldn't have joined Muzan and become "Kuroshibo".

Don't worry.

Following Uchiha Hikaru's gaze...

Master Cat put the last few pieces of dried fish into his mouth, swallowed them, and then licked his paws: "I've already carefully examined Tanjiro. The reason why the 'Scarlet Mark' shortens lifespan is because this power itself has a flaw. From the moment it's activated, it continuously consumes the energy in the body..."

It's like piercing a small hole in a water container; after a while, all the water will drain out.

The solution is to use "qi" to patch the loophole, thereby preventing that situation from occurring.

I've figured out the specific method for using it and taught it to Tanjiro. Whether he can master it or not is up to him.

"I see."

Uchiha Hikaru nodded.

The training system in the Dragon Ball world is a superior version of "breathing techniques," and "ki" is a highly versatile ability that can be used to compensate for the shortcomings of "stripes," so it is not surprising.

the other side.

The Cat Sage glanced at Uchiha Hikaru again: "Did you come here this time because there's something else you want to tell me?"

"There are indeed two things."

Uchiha Hikaru cleared his throat and said with a grin, "The first thing is about the Red Ribbon Army..."

"The Red Ribbon Army?"

The cat sage only needed a moment's thought to understand: "I did see some scenes about them in the water tank. According to the humans in the lower realm, they are the most evil legion in the world, having done many heinous things. Many people tremble at the mere mention of their names..."

"If you want to eliminate them, it would be a good thing for ordinary humans as well."

"Does Master think so too?"

In fact, Goku in the original work had already done the task of eliminating the Red Ribbon Army, and it did not affect his reputation in the eyes of the Nekomamushi.

However, Uchiha Hikaru was, after all, from another world and had never been suppressed by the Red Ribbon Army. Suddenly wanting to deal with them seemed a bit like overstepping his bounds.

So I mentioned it to the cat sage in advance, just to give him a heads-up.

Of course, if Uchiha Hikaru hadn't been working hard to improve the Cat Sage's favorability over this period, the latter probably wouldn't have been so easy to talk to.

As for the second thing she wanted to ask...

"It's about Dragon Ball."

Uchiha Hikaru carefully considered his words before slowly speaking, "Master, what do you know about the Dragon Balls? If... I mean, if we wanted to borrow the Dragon Balls to use in another world, would that be possible?"

"?"

The cat sage paused in his whisker-licking motion, seemingly surprised, his squinting eyes almost opening wide: "Another world?"

"Yes."

Uchiha Hikaru nodded: "I don't know if Tanjiro has told you about the Demon Slayer Corps. Many members of the Demon Slayer Corps have friends or family members who died at the hands of 'demons,' and some of them themselves have also died... Tanjiro and I are thinking of trying to revive them using the Dragon Balls. I don't know if it's feasible."

"..."

The cat sage fell silent.

half an hour.

It opened its mouth and said, "I can't give you a definite answer to this question either. You might have to ask the creator of Dragon Ball."

"The creator?"

"Yes, it's a god."

The cat sage pondered for a moment before speaking again: "The gods reside in their temples, far removed from the mortal world, and do not easily meet with humans. I can inquire for you; if the gods are willing to grant you an audience, I will inform you."

"Thank you very much, Master!"

Uchiha Hikaru smiled, pursing his lips.

Several days ago, when she decided to go to the Dragon Ball world to collect the Dragon Balls again, she had carefully considered these issues.

First of all.

Collecting the Dragon Balls isn't too difficult; the main competitor is the Red Ribbon Army. Once you take them down, you'll be fine.

King Pilaf also participated in the search operation, but he was just a comedic character and a very ordinary minor supporting character. At most, he would cause her some trouble, but he was not worth worrying about.

Second.

Bringing the Dragon Balls to other worlds isn't difficult; it's just a matter of "traveling."

But the problem is...

Dragon Balls that are taken directly to other worlds will most likely not be able to summon Shenron.

After all, the power of the Dragon Balls originates from their creator. In the original timeline, the Dragon Balls lost their function after Kami's death, so bringing these things to another world would likely have the same effect as Kami's death: once the connection between the two is severed, it becomes impossible to make wishes normally.

Even assuming everything goes smoothly, there's still one problem—

After a wish is made, the Dragon Balls turn into a pile of stones and fly away. If she manages to "borrow" them all and can't bring them back, it wouldn't be easy to explain to the Dragon Ball world…

and so.

We still need to find a way to meet with the gods and selectively clarify things.

If the gods are unwilling to help, or if the Earth's Dragon Balls can't do this, then we'll have to try our luck on Namek again...

"I entrust the matter of seeing the Heavenly God to my master."

Uchiha Hikaru said very respectfully.

Since the cat sage didn't mention that the Heavenly Temple was located above Korin Tower, she pretended not to know that.

"Tanjiro's words..."

"This kid has good talent and a lot of perseverance. He's almost managed to get the Super Elixir these past few days. If you have something to do, you can take him with you first, and he can come back for the final stage of training after you're done."

"The cat sage said, stroking his beard."

present.

Uchiha Hikaru gave the cat sage the gift he had prepared in advance, said goodbye to the latter, and then left Korin Tower with Tanjiro.

Because his training period is still short, Tanjiro has not yet learned the art of flying.

However, he had the golden Flying Nimbus given to him by the Cat Sage, so his speed was not much slower than that of Uchiha Hikaru, who used the Flying Technique.

Uchiha Hikari was somewhat envious of this "genuine" Flying Nimbus, but since she couldn't ride it, she could only admire it from afar.

"By the way... I wonder if Kikyo and the others will be able to ride the Golden Flying Cloud?"

Uchiha Hikaru thought for a moment.

Kikyo goes without saying; her heart is so pure that she can use "Purification Light," so there's no reason why she can't ride the Flying Cloud.

What others say...

Erii and Yotsuya Miko might also work, followed by Yamato—this Oni Princess's thought process is a bit peculiar, but her mind can indeed be described as pure, so it's not surprising that she can ride the Golden Flying Cloud.

On the other hand, Brand and Yuujin Itadori, although they are kind-hearted, one has a lot of blood on his hands and the other has Sukuna on his body, so they are probably not suitable.

Lost in thought all the way, and after chatting with Tanjiro about "ki" for a while.

The two returned to the Capsule Corporation in West City and met Bulma and the others again.

Yamato had already returned from shopping with Brigitte. As soon as he saw Uchiha Hikaru, he rushed over with a look of surprise and gave her a face wash.

Um... it's just "facial cleanser" in the literal sense.

As half of Uchiha Hikaru's body sank into the cleavage of Yamato's chest, Esdeath and Tanjiro beside him both had strange expressions.

"...Okay, Yamato, let me go, I can't breathe."

Uchiha Hikaru felt the large, soft yet elastic texture on both sides of his cheeks, patted them a couple of times, and muttered something under his breath.

After Yamato got up, she took a few breaths and introduced Tanjiro to her.

"Hey, you're that 'Iron Head Kid' from the group?"

Yamato squatted down in front of Tanjiro, curiously touching his forehead with her finger: "Is your forehead really that hard? Can you bump it against mine and see?"

"This isn't quite right, Miss Yamato..."

Tanjiro hesitated for a moment.

"It's okay, a little bump won't break anything, come on, come on~"

At Yamato's insistence, Tanjiro finally nodded in agreement. Both of them took a deep breath, leaned back slightly, and then suddenly bumped their foreheads together.

bang——

With a crisp sound, a small cut appeared on Yamato's forehead, from which blood flowed out, while Tanjiro also covered his forehead, but was clearly unharmed.

Uchiha Hikaru and Bulma, who were watching from the sidelines, looked at each other in bewilderment.

"6".

"Even Yamato..."

If Tanjiro and Yamato were to fight, there would be no doubt that their chances of winning would be 19/10. Even if Tanjiro had mastered "ki," he would have absolutely no chance of defeating Yamato, because the difference in their abilities would be too great.

but……

In a contest of forehead hardness, even Yamato, who inherited Kaido's physique, couldn't beat Tanjiro. It seems the latter's title of "Iron Head" is truly well-deserved.

the other side.

Esdeath only glanced at Tanjiro a few times before paying no further attention.

Tanjiro's strength is not enough for her to take him seriously.

That evening.

Bulma's family prepared a lavish feast to entertain Uchiha Hikaru and the others who had traveled from afar.

After everyone had eaten and drunk their fill, Brigitte began arranging where the group would sleep that night.

Meanwhile, Uchiha Hikaru found Dr. Brief and gave him several letters Orochimaru had recently written regarding academic exchanges. He also obtained the previous reply from Dr. Brief, intending to give them to Orochimaru after returning from this trip.

During this process, Dr. Brief briefly mentioned the progress of the "Uchiha Clan Bloodline Tracing Project".

"I've made some progress in this area recently."

"Based on a series of laboratory analyses and comparative experiments, it is clear that there is indeed a genetic defect in the bloodline of the Uchiha clan. It is this defect that causes the brain structure of the Uchiha clan to be more abnormal than that of ordinary people. This leads to the accumulation of negative emotions generated in daily life, resulting in the inability to release emotions for a long time, thus forming the so-called 'bloodline disease'."

As the process of "awakening the eye" deepens, this defect will not only not be remedied, but will become even more severe. Therefore, the more magatama one has, especially after the "Kaleidoscope" is awakened, the more serious this bloodline disease will become...

After explaining the medical findings.

Dr. Brief got to the point: "Based on these experimental results, I have developed a gene-targeting drug that can repair the genetic defects of the Uchiha clan through intravenous injection... In addition, it can stimulate the eye cells of the Uchiha clan without triggering the disease, making their pupils more stable."

"Oh?"

Uchiha Hikaru raised an eyebrow: "The raw materials for that potion, could they be...?"

"Yes, I referenced the genetic samples of 'Naruto Uzumaki' and 'Karin Uzumaki.' These genetic samples seem to also be effective in the blood sample from the patient named 'Kimimaro' that you sent last time, Miss Hikari..."

After a pause, Dr. Brief continued, "However, these results have only been successful in the laboratory so far, and no clinical trials have been conducted. It is still uncertain whether there will be any rejection reactions when used on living humans."

This is normal.

Aside from Hikaru Uchiha, all those with Uchiha bloodline are in the Naruto world. Therefore, they cannot be used for clinical trials.

"Please give me a few samples of this medicine. I'll recruit some of my tribesmen to try it next time I go home."
