Simultaneous travel: I am proving the great way in the heavens

In fact, it's not hard to understand Uchiha Fugaku's shock.

Because a ninja's ninjatō are usually small daggers for easy carrying.

Sakumo Hatake's White Light Chakra Saber, forged from chakra metal, is even less than a foot long.

Weapons forged from chakra metal are rarely too large, not because they can't be made, but because there's not enough capital.

Simply put, chakra metal is too precious.

At this moment, Rōfu opened his mouth and directly asked Uchiha Fugaku for a katana forged purely from chakra metal.

Actually, with the Uchiha clan's thousand-year heritage, it's not impossible to obtain so much chakra metal, but the cost would be too great.

Rōfu pretended to be embarrassed, lowering his head and saying, "Is... is my request too much? If that's the case, then it's okay."

"No! No! No!" Having just won Rōfu over to his side, Fugaku believed that with their past friendship, plus future cultivation, he could even turn Rōfu into his loyal follower.

And at this crucial moment for building closer ties, he absolutely couldn't let this bit of reluctance cause a rift between them.

Gritting his teeth, Uchiha Fugaku braced himself and said, "Your request isn't excessive. It's just a katana forged from chakra metal, right? My Uchiha clan, a thousand-year-old noble family, how could we not even be able to produce something like that? Besides, you've awakened those legendary eyes. You draw a sketch of the katana you want, and I'll immediately dispatch the Ninja Cat clan to send the message back to the clan, striving to have the Ninja Cats deliver the chakra katana to your hands in a few days."

Among the Uchiha clan members, although there are many kinds of summoning beasts, in general, most Uchiha will choose to sign a summoning contract with the Ninja Cat clan.

Summoning beasts like Itachi Uchiha's crows and Sasuke Uchiha's association with the Earth Dragon Cave are actually in the minority among Uchiha summoning beasts.

Rōfu was naturally the same. At first, he also thought about whether to sign with a few stronger summoning beasts.

But unfortunately, the Uchiha clan could only provide Ninja Cats. As for other summoning beasts, it depended on one's own opportunities. You could sign with whatever you wanted if you had the chance; if not, it's better to honestly sign with Ninja Cats.

Of course, if you really didn't like Ninja Cats and couldn't find other summoning beasts, you could simply not sign with any summoning beasts, or cultivate your own from scratch.

Rōfu neither had the opportunity to find other summoning beasts nor the patience to cultivate his own, so he simply followed the crowd and signed a summoning contract with the Ninja Cat clan, just like the other Uchiha.

"That's great." Rōfu revealed a look of pleasant surprise, went directly to Uchiha Fugaku's temporary desk, grabbed a piece of white paper, and quickly drew a sketch of a katana on the paper.

This katana, or more precisely a ninjatō, was almost no different from a samurai sword from the Land of Iron. It was three feet long, three fingers wide, slightly curved, and the circular tsuba (handguard) had three hollow tomoe (comma-shaped) patterns in addition to some patterns. Other than that, from the hilt, there was nothing special about it.

But if this sword were really forged, even Fugaku would have a headache about how to explain it to the clan elders.

"Very... very good!!" Uchiha Fugaku's expression returned to his usual seriousness, but the heartache and reluctance between his brows couldn't be completely concealed. "A very beautiful katana, and it fits our Uchiha clan's style very well, but... isn't the thickness and width a bit too much?"

Under normal circumstances, ninja swords pursue speed. Therefore, they won't be too thick or too wide. Although increasing the weight can indeed enhance the power of slashing, it will inevitably lead to a lack of speed and require more strength, which is not conducive to protracted battles.

"It's okay, I have a lot of chakra. Besides, the increased physical recovery after awakening the Mangekyō has also made my strength greater. This sword is the most suitable for me. If it's too light, it won't feel right." Rōfu pretended not to understand the subtext of Uchiha Fugaku's words.

In fact, his sword was exactly the same as Rōfu's Nichirin Sword from Demon Slayer.

Don't forget that before Kibutsuji Muzan forcibly turned Rōfu into a demon, he was also a pillar-level existence in the Demon Slayer Corps. The Star Breathing he developed directly chased the Sun Breathing, the ancestor and foundation of breathing techniques.

Because only seven sword forms had been developed, it was slightly inferior to Kokushibo's Moon Breathing, but its potential was by no means inferior.

The all-around enhancement brought by Star Breathing was enough to make Uchiha Rōfu become a master of swordsmanship in one leap, even reaching or even surpassing the former Konoha White Fang to a certain extent.

And completely forging a chakra ninjatō like the Nichirin Sword would save Uchiha Rōfu from the process of exploring and adapting to Star Breathing, allowing him to turn into actual combat power as quickly as possible.

Now Uchiha Fugaku had nothing to say and could only endure the heartache, summoning his summoning beast Ninja Cat and transmitting the blueprint of the sword back through the summoning technique.

After doing all this, Uchiha Fugaku said, "Next, you only need to be patient for a few days, and you will soon be able to get your own ninjatō. Before that, I have some clan secret techniques to impart to you. Next, you will temporarily stay in my tent and act as my guard."

Uchiha Fugaku, who had also awakened the Mangekyō, knew very well how terrifying the improvement was for an Uchiha clan ninja who had awakened the Mangekyō.

However, if the surging power cannot be perfectly controlled, accidents may occur.

Rōfu had awakened the Mangekyō. If he were to die on the battlefield of Kirigakure, it would definitely be a huge loss to the clan.

As the clan leader, Uchiha Fugaku hardened his heart and chose to impart the two great forbidden techniques of the Uchiha clan to Rōfu, in order to give him a few more trump cards to protect his life.

Izanagi and Izanami.

Izanagi is the ultimate dōjutsu unique to the Uchiha clan. Although the price is huge, once used, it will permanently lose an eye. But the effect is equally amazing, that is, rewriting reality.

Erasing all factors that are unfavorable to oneself and turning only factors that are beneficial to oneself into reality.

This kind of dōjutsu with a huge price, even in the Uchiha clan, is a forbidden technique, but it's not that no one can learn it, it's just that the conditions for learning are a bit harsh.

And the other dōjutsu, Izanami, is simply designed to target the former, which can cut off time within a certain range, form a self-contained cycle, and completely turn it into an infinite loop.

Rōfu really didn't expect that provoking Uchiha Fugaku's seven deadly sins would bring him such great gains.

First, he imprinted Uchiha Fugaku's two Mangekyō dōjutsu, the ability to foresee the future and the powerful Tsukuyomi genjutsu, then obtained a surprisingly heavy chakra sword from the clan's property as if cutting flesh, and even Izanagi and Izanami were taught to him by Uchiha Fugaku.
