"Oh, you two came down to greet me so early."
In the plaza below the apartment building, Tatsumaki floated in mid-air, looking at Meikyō and Fubuki with a happy expression.
"Yes, yes, you came quite early too, sister. We almost didn't have time to get ready."
Fubuki smiled and put her arm around Tatsumaki's.
"Look at you, how old are you? You still can't even dress yourself properly, and your clothes are all wrinkled."
Tatsumaki shook her little head and pointed at her sister.
Fubuki's outfit appeared normal, but it was actually hastily put on in a few dozen seconds, so many details were naturally not handled well.
Tatsumaki stood on tiptoe and laboriously helped Fubuki turn up her collar.
At this moment, Meikyō also opened the Teleportation Circle.
"Let's go. The matter we discussed last time has been resolved. Now you and I should both be able to exercise in that Gravity Training Room."
Upon hearing this, Tatsumaki's eyes lit up, and she grabbed Fubuki and rushed into the teleportation portal.
"You're here. Please make yourselves at home. Wait a moment. Meikyō, I haven't fully grasped the information you gave me yet. I'm still studying it. But if it's just a matter of simply copying it, making a couple of copies shouldn't be a problem."
Genus, wearing goggles, was operating a robotic arm on the lab bench, welding something.
"Shall we begin now?"
Meikyō pointed to the Gravity Training Room next door.
"I've already modified the power generation system. You guys embed those two Arc Reactor on the table into the recesses behind the Gravity Training Room, install and calculate. These two reactors can power the Black Hole Class training room for three hours, enough for you to use it twice."
Genus briefly pointed to the location of the power generation system before getting back to work.
Meikyō picked up the two Arc Reactor on the table, exchanged a glance with Tatsumaki, and walked together to the front of the training room.
With a click, the two Arc Reactor were installed behind the Gravity Training Room under the influence of Psychic Power.
Meikyō stepped into the training room.
The Tatsumaki brought with it Psychic Power Directional Brainwave Amplifier.
Fubuki pressed the start button.
That familiar feeling again!
A large amount of blood and energy surged out from the Ama-no-Ohabari, and was greedily absorbed and digested by every inch of Meikyō's body.
Thick red mist rose, causing Meikyō's body to emit blood-red steam as if the Gate of Death had been opened.
In the past, the Gravity Training Room on the White Dwarf Class could no longer provide him with much improvement, which means that Meikyō's physical body has far exceeded the normal Boros when he removes his metal armor.
The gravity of Black Hole Class is somewhat overwhelming for the current Meikyō, and it is expected that it will be difficult to maintain the stalemate for more than two hours, which is similar to Boros.
Because Boros cannot maintain the state of energy release for a long time, and for Boros, maintaining it for too long would even affect his lifespan.
Because Meikyō has a large amount of blood energy absorbed by Ama-no-Ohabari in the past as a supplement, her training is not simply about squeezing her physical body, but rather about having enough replenishment, so there will be no serious side effects for a certain period of time.
Meikyō still couldn't sense the limits of his physical body.
He now possesses the bloodlines of the Senju, Uzumaki, and Uchiha, making him nearly identical to Hagoromo Otsutsuki. This means he has almost half of the Otsutsuki bloodline, and his physical potential is actually close to that of the real Otsutsuki.
It's hard to say how high the limits of Otsutsuki's physical body are.
Both Kaguya and Ōtsutsuki Isshiki had the experience of directly smashing the Perfect Susanoo with their bare bodies.
Kaguya used the Eighty Gods Vacuum Attack, while Isshiki Perfect Susanoo Sasuke's Complete Susanoo with a single punch while still in the Karma 2 state, which was not yet fully revived.
Meikyō can now easily defeat a Super Kage-level fighter who can use Perfect Susanoo. A single Void Flame Gravity Slash can destroy the Perfect Susanoo of Shisui and Fugaku with their Eternal Mangekyo Sharingan. However, if it comes to relying on physical strength, even with the use of some techniques and energy enhancements, he cannot defeat them in one blow with his bare body.
Previously, against conventional enemies, Meikyō's physical strength and Taijutsu gave him a significant advantage. However, in this level of competition, Meikyō could only ensure that he would not fall into a major disadvantage in physical combat and that he had an equivalent level of endurance.
His greatest strength lies in his ability to manipulate space and time, combined with his swordsmanship, Ninjutsu, and other skills, which give him tremendous offensive power.
Fortunately, Meikyō has now found a way to continue to rapidly enhance his physical abilities and strengthen his foundation.
According to Meikyō's current estimation, once he can withstand Black Hole Class gravity with relative ease, or even treat this intensity of gravity as ordinary, he should be able to destroy the Perfect Susanoo with a single punch.
Although he didn't know where his limits were, Meikyō believed that this Black Hole Class Gravity Training Room should be able to help him get close to his limits. If he couldn't reach them, it wouldn't matter. At that time, with his physical strength, he should be able to directly withstand the gravity and high temperature of large celestial bodies. He could then train directly on those large stars.
The route planning is very clear, and the only problem Meikyō has now is the blood energy in the Ama-no-Ohabari Feather.
Judging from the current trend, Meikyō estimated that the large amount of blood energy he had painstakingly absorbed might only be enough for him for three or four months.
This can certainly bring about significant progress, but it is far from the limit.
It seems that, in addition to understanding the Infinity Stones and daily training, I need to consider the issue of blood and qi.
"Boom..."
More than an hour later, the door to the Gravity Training Room was opened.
Meikyō, panting heavily, walked out of the door with unsteady steps.
On the other side, Tatsumaki, her green hair soaked with sweat, slumped weakly in her seat. With Fubuki's help, she removed the directional Psychic Power brainwave amplifier from her head.
"One hour and twenty-one minutes, that should be our current limit. The remaining energy should be enough for us to use once more."
Meikyō pulled up a chair and sat down next to the dashboard.
Actually, this limit is the limit of Tatsumaki. Meikyō is slightly less than that, but it's like a person who exercises regularly running several kilometers. It's very tiring, but not to the point where they can't even stand up.
He estimated his limit to be around one hour and forty minutes.
The electricity that Genus had accumulated over a month was used up by Meikyō and Tatsumaki in just over half an hour.
The event lasted for over forty minutes, putting considerable pressure on Meikyō and Tatsumaki. This led Tatsumaki to believe that if she could use this device frequently, it could be used as part of her daily training to develop Psychic Power that were almost impossible to improve through other means.
Because unless it's Psykos-Orochi, Garou, or seven or eight Dragon-level monsters attacking together, it's difficult for Tatsumaki to feel any pressure.
Although her Psychic Power are strong, they weren't that strong right after she came out of the laboratory. She only acquired combat power above that of a dragon after experiencing many battles in her early years.
"This thing is somewhat useful. If I can keep training to this level every day until I can better withstand this level of Psychic Power consumption, perhaps one day I will be able to use Psychic Power to move space."
After resting for a while, Tatsumaki stood up from her seat and said happily.
The main thing is that Fubuki's Psychic Power is the ability to help people restore their physical strength.
At this moment, Fubuki also stood behind Meikyō, stretched out two slender white fingers and pressed them against the Solar System, gently kneading and massaging it. A layer of blue-green light rippled across Meikyō's body like water.
"By the way, Tatsumaki, I need to ask you a favor."
Meikyō removed the Ama-no-Ohabari and threw it forward.
Bruce materialized into a blood-red bat the size of a pigeon, which flew through the air before landing on Meikyō's shoulder.
"I've been quite busy lately, so I'm thinking of having you and Fubuki help take care of Bruce."
Tatsumaki wasn't too surprised, because Meikyō had shown Bruce during Boros's invasion.
The Bruce was over ten meters long at the time and could carry several people.
"I might be quite busy lately, and I usually only have clones left behind. Although they have the fighting power of S-Class Hero, they can't be maintained for long once they consume too much energy. So I hope that when you are dealing with monsters, you can have Bruce absorb the monsters' blood energy. I also need a lot of blood energy to maintain my daily training."
Tatsumaki lay on the table, staring wide-eyed at Bruce.
"I've wanted to ask this for a long time: is this thing a sword or a bat? If it's a bat, does it eat? What does it eat?"
Tatsumaki asked Meikyō.
"It doesn't eat normally. You just need to take it hunting some monsters with strong blood energy regularly. While absorbing the monsters' blood energy, it can filter the blood energy, keeping a portion for its own food. The remaining pure blood energy can be absorbed by the human body during training to strengthen the physical body. Fubuki, didn't you say before that you wanted to continue to strengthen your strength through physical means? When you have a relatively high physical fitness, you can try using a little, but not too much. The blood energy here is at least what I absorbed from Dragon-level monsters. If your physical fitness is not strong enough, you can easily overeat."
Fubuki nodded her head, looking bewildered.
"Can I see this little thing too? It's called Bruce, right? It's very unscientific that it can transform from non-organic metallic matter into a living organism."
After finishing his work, Genus came over and stared at Bruce.
"Just don't cause any trouble."
Meikyō shrugged at Genus.
Back in the Pirate World, Caesar and his crew did a lot of research on Bruce.
Come to think of it, I haven't been focusing on the Pirate World much lately.
Although the average combat strength is stronger, the Pirate World can only help people reach the level of the Admiral and the Four Emperors at most. The Naruto World has a weaker average strength, but the upper limit of the Six Paths level is there.
However, this doesn't mean that the Pirate World can't help Meikyō now.
"Oh, right, Doctor, there's one more thing I need to ask you."
Meikyō, watching Bruce playing with Tatsumaki, suddenly spoke to Genus.
"If possible, could you make me a sword that is strong enough? The Ama-no-Ohabari is not with me, but I still need a sword to maximize my strength. It doesn't need to be too sharp, but it must be strong enough and preferably resistant to high temperatures."
"A weapon that is strong enough...that's a bit difficult. Although the metal materials on Boros's ship are excellent, they may not necessarily meet your needs. After all, if they really had strong enough metal, Boros would definitely have already used it to make weapons."
Genus rested his head on his hand and stroked his chin, speculating.
If a sword is made of paper, it's not very useful. At least for a powerhouse like Boros, whose fists can shatter almost any known metal, a sword would be blasted into pieces if it hits his fist. There's really no need to equip such a weapon.
The Ama-no-Ohabari Feather is made of a special material, but if it were still in its original form, it would be difficult to withstand a battle at the Six Paths level. It was first strengthened by the Bat Fruit, and then imbued with the Haki of the Meikyō Haki for many years. Furthermore, during battle, the Mirror Spirit would also attach Haki to the surface of the sword, which is why the Ama-no-Ohabari can fully unleash its current strength.
In theory, if the strength of Armament Haki is sufficient, it doesn't matter if you only have a sword made of ordinary metal.
The problem is that Meikyō's overall strength has increased too quickly. His physical body, which was originally his strength, is not a weakness, but that's about it. This makes his Armament Haki somewhat unable to keep up with his Six Paths level strength, and it can only be used as an ordinary enhancement buff during battle.
"If you want metal that is hard enough, you can apply to the Hero Association. Ten years ago, Blast obtained some unknown metal in another dimension. It was very hard and therefore difficult to process. He later donated it to the Hero Association. Some of it was taken by Metal Knight for research. In the end, it took hundreds of diamond drill bits to barely grind it into a long strip. Finally, Metal Bat used it as a weapon. The rest is still in the Hero Association. If you, me, and the four S-rank, Fubuki and Genos, apply together, we should be able to get most of it, enough for you to make a sword, provided that you have enough processing skills."
Tatsumaki suddenly spoke up from the side.
Despite her youthful appearance, she is actually nearly thirty years old and a veteran member of the Hero Association. She was already involved in hero activities under Blast's influence more than a decade ago, before the Hero Association was even established. It's no exaggeration to say that she is very knowledgeable.
"Can you barely make it with diamonds? Then I should be able to make it with some space alloys salvaged from the spaceship as drill bits, it just might take a bit longer."
After listening, Genus speculated.
"I wonder what the melting point of this metal is? It doesn't matter if it's too high, there's always a flame that can melt it."
Meikyō stretched out her hands, with a ball of Amaterasu Black Flame floating in her left hand and a ball of Blaze Release blue flame floating in her right hand.
He estimated that using the Azure Flame Release should be enough, since the Blaze Release technique can directly break down matter into molecules.
