A Flash of Inspiration

"What a treasure—this is what kept the corpse's chest so plump and full of blood!"

"Still, the pendant's real use should be leveraging the cold to keep the cultivator's mind calm and icy, allowing them to push forward fiercely without worrying about qi deviation."

Uchiha Shūichi let out an admiring sigh, then looked down at the corpse with blood trickling from all seven orifices—clearly a miserable death from qi deviation—and curled the corner of his mouth.

Obviously, everything in the world is relative; ignoring dosage when talking about toxicity is pure thuggery. Faced with that incredibly sinister sword, the Blazing Kirin Sword, which could be called the king of demon blades, this pendant wasn't just barely better than nothing—it was a drop in the bucket.

Besides this Ice Crystal Pendant, Uchiha Shūichi also found a cool piece of brocade on the corpse, likely made from treasures like ice silkworm silk. It had a slight calming effect on the mind, but it was far inferior to the Ice Crystal Pendant.

However, that piece of brocade was covered in tiny handwriting. Though it was traditional Chinese characters, Uchiha Shūichi could still translate it.

"Mind as ice, clear as frost; heaven falls, no shock; ten thousand changes, still as rock; spirit at ease, breath still..."

"That sounds so familiar—isn't this the Ice Heart Art from Fung Wan?"

Muttering a few lines, Uchiha Shūichi reached a conclusion. Then he looked at the demon sword on the ground, then at the brocade in his hand:

"Could this really be something from the Fung Wan world? And who was this dead guy? And that Blazing Kirin Sword—its power far exceeds imagination... Could it be some abstract version of the Fung Wan world?"

In long-running Japanese manga, there's often a power inflation and collapse of the combat system in the later stages. But honestly, Hong Kong comics inflate power far more than Japanese ones. In the later stages of the Fung Wan world, power inflation leads to a super-powered Blazing Kirin Sword... that doesn't seem impossible?

Uchiha Shūichi's mind was full of random thoughts. Though the Fung Wan manga was popular, he hadn't read much of it in his past life—just watched some TV dramas and listened to online discussions. He didn't know much about it.

If he really understood it, he'd know that in the original Fung Wan story, the Blazing Kirin Sword didn't get any subsequent upgrades—it shattered directly and was never reforged.

But even without reading the original, Uchiha Shūichi didn't think that possibility was very likely. Instead, he leaned toward another explanation.

This peculiar corpse might also be a transmigrator like himself—only he went to the Naruto world, while the other went to the Fung Wan world.

Just as he had schemed to obtain Kotoamatsukami and Hashirama Cells in the Naruto world, that transmigrator in the Fung Wan world would surely have stirred up the world's situation, turning everything upside down.

In that process, the original Blazing Kirin Sword might have undergone countless adventures and enhancements, evolving from a second-rate divine weapon into an unimaginably overpowered one—in fact, Uchiha Shūichi felt this was the true explanation.

Otherwise, the corpse wouldn't have prepared so many things. Whether it was this strange Ice Crystal Pendant or the Ice Heart Art manual, they were all meant to suppress this Blazing Kirin Sword.

The authentic Blazing Kirin Sword did have the flaw of the sword controlling the wielder's mind, but it still took time. Even ordinary people could use the sword—how could it be this sinister!

And this corpse had no martial arts manuals on it, only this Ice Heart Art. In the Fung Wan world, the Ice Heart Art is purely a supplementary mental technique—it calms the mind but offers no boost to martial arts.

It does have some value—a higher mental state helps with learning techniques and accumulating internal energy—but it's certainly not some supreme divine art. Its greatest use is suppressing qi deviation.

This corpse left no other manuals on it, only the Ice Heart Art. He must have studied and pondered it daily, all in an attempt to control the Blazing Kirin Sword.

But whatever the truth, Uchiha Shūichi could never know it now. He couldn't use the Blazing Kirin Sword yet, but after carefully studying the Ice Heart Art, he found it quite beneficial.

Unlike normal martial arts manuals, the Ice Heart Art is purely a mental technique for visualization, concentration, and steadying the mind. It doesn't involve internal energy cultivation or meridians and dantian, so it won't conflict with the Chakra system. Instead, it further refines one's spirit.

Chakra is essentially the fusion of physical energy and Mental Power. With a more concentrated spirit, both Chakra and Yin Release levels can rise accordingly.

For the Uchiha Clan, who are naturally adept at Yin Release, the Ice Heart Art's effects are even greater.

The only slight drawback is that the Ice Heart Art suppresses the Uchiha Clan's emotional fluctuations, which might hinder the awakening of the Sharingan.

But the Mental Power condensed through the Ice Heart Art also lowers the emotional threshold required to awaken the Sharingan. Overall, it's still a net gain.

Most importantly, after cultivating the Ice Heart Art, the mental shock caused by the Sharingan's awakening on Uchiha ninjas is greatly reduced—specifically, it means fewer Uchiha turning into psychopaths!

The Ice Heart Art might not fully counter the mental shock from the Mangekyo, but it can still reduce it significantly. For the ordinary One Tomoe to Three Tomoe, it can basically stabilize the mind completely, making them no different from normal people.

Whether he'll pass the Ice Heart Art to the Uchiha Clan later is another matter, but for now, Uchiha Shūichi can use its power to refine his spirit. There's even a slim chance he might glimpse the true Mangekyo Sharingan.

Though the transplanted Kotoamatsukami Mangekyo is almost fully integrated into him now, it's still Uchiha Shisui's Mangekyo. No matter how well Uchiha Shūichi and the Kotoamatsukami Mangekyo resonate, it can never surpass his own original eyes.

However, thanks to the feedback from the Kotoamatsukami Mangekyo, combined with his body modifications and powerful Mental Power, Uchiha Shūichi's difficulty in awakening his own Mangekyo is far lower than that of an average Uchiha.

Even Uchiha Itachi, Uchiha Shisui, and Uchiha Obito can't match him in this regard.

But Uchiha Itachi, Uchiha Shisui, and Uchiha Obito are all beings of excessive emotion, while Uchiha Shūichi is cold and selfish. That's why he's never been able to awaken his Mangekyo like them.

Now, though, Uchiha Shūichi has thought of a better way to help himself awaken the Mangekyo.
