The Heavens: One World, One Superpower

Kagaya Ubuyashiki said, "I've arranged a hot spring bath for you in the swordsmith village. The hot spring there can accelerate your body's recovery, and the mysterious substances it contains can greatly enhance your physique. It's a rare opportunity."

Su Chen's eyes lit up, and he exclaimed excitedly, "The legendary swordsmith village?"

Kagaya Ubuyashiki laughed and said, "That's right, that place is very special. There is a sun-drenched mountain that is exposed to the sun all year round. The ores inside can absorb the power of the sun. They are crimson sand iron and crimson ore, which contain solar energy and can suppress the regeneration of demons. I have already informed the village chief of the swordsmith village and asked him to arrange for the top swordsmith to make a Nichirin Blade that is made just for you."

"Thank you, it seems like this is going to be a very exciting trip."

Kagaya Ubuyashiki left.

They agreed to depart for the knife-maker village ten days later.

After all, Su Chen can't withstand any more stress right now and needs to recover from his injuries.

And so, Su Chen basked in the sunlight every day.

Absorb the sun's power to your heart's content, repair your body, and strengthen your physique.

They also had a pleasant daily chat with Kanae, the flower pillar butterfly.

It was a truly wonderful time.

Gradually, he recovered.

His physique was actually twenty-five times that of an ordinary person, a full tenfold increase.

The punching force reached tens of thousands of kilograms.

One punch from him could probably smash even a meter-thick block of iron to smithereens.

Moreover, the electromagnetic radiation range in the mind reached a radius of fifty meters.

Within a range of fifty meters, everything was clearly visible; nothing could escape his perception.

Due to the interference of the soil layers, the depth can only reach twenty meters.

But that's still quite remarkable.

Furthermore, it pioneered X-ray vision, which not only allows observation of the exterior of objects but also reveals their internal structure in detail.

Within a 50-meter radius, no object's internal structure can escape his perception.

This is practically a budget version of "The Transparent World".

The duration of the thermal vision was extended from ten minutes to one hour.

In other words, the body contains more solar energy.

The range of the cryogenic breathing device reaches 300 meters and can generate a strong wind.

Clenching his fist, Su Chen felt a surge of power within him.

"It feels like it's moving towards a more mature version of DC Superman. I wonder if it can surpass DC Superman?"

"With this physique, I am probably at the pinnacle of all the Pillars. Even the Stone Pillar, Gyomei Himejima, wouldn't dare say he has a physique that is twenty times the human limit."

"Now, using the Sun Breathing Technique 3 again will no longer burden the body."

"I just don't know if I can reach Yoriichi Tsugikuni's level now, or if I can kill Muzan Kibutsuji alone."

This is hard to say.

After all, Yoriichi Tsugikuni is the pinnacle of power in the Demon Slayer world, a legendary swordsman destined for greatness, ridiculously strong.

He was born with freckles and a clear view of the world. And he was not cursed by the 25-year-old curse of freckles, living to be over eighty years old.

What is the condition of the markings?

A superhuman state where the heart beats 200 times per minute and the body temperature is maintained at 39 degrees Celsius.

In the original story, even a Demon Slayer Pillar-level swordsman could only maintain his Demon Slayer Mark for a period of time, but he maintained this mark from birth to death.

That is, for more than 80 years, his body temperature has been 39 degrees Celsius and his heart rate has exceeded 200 beats per minute.

Yoriichi Tsugikuni was born with a breathing technique, using the Sun Breathing method to enhance his physique from childhood, thus imbuing his body with a large amount of solar energy. This allowed him to permanently turn his Nichirin Blade red, ensuring the blade's eternal red color.

He can use the twelve forms of Sun Breathing continuously and seamlessly, forming the thirteenth form.
