Senju Hashirama stopped his casting wind-up and turned to look at Senju Touka.
"What is it?"
"Clan Chief, Uchiha Madara has invited you to a decisive battle ten days from now at Sengokugawa River."
"Haha… Good, I accept." Senju Hashirama laughed and agreed, not needing to think about such a decision.
Rosen and Senju Tobirama both breathed a sigh of relief. If the fight continued, Senju Hashirama would definitely unleash his killing moves, and neither of them was confident they could block Senju Hashirama's killing moves.
"I'm not fighting you anymore. I need to prepare well for the duel with Uchiha Madara in ten days." Senju Hashirama waved his hand and turned to leave.
Rosen came to Senju Tobirama's side. Senju Tobirama glanced at Rosen's arm: "How's your arm?"
"My the awakening of the spirit has awakened a skill similar to Seal-less Self-Healing, which can also quickly repair damage to the Physical Body."
Senju Tobirama was quite envious; he still had some way to go before his Great Cold Energy reached Perfection.
"That Ice Dragon you cast was too slow."
"I can't help it. I have to first cast Water Dragon Ninjutsu, and then use Great Cold Energy to transform the Water Dragon into an Ice Dragon."
The Wood Release Ninjutsu Senju Hashirama uses is a Bloodline Limit, requiring no hand seals.
Every time he makes a move, he just claps his hands, and whatever he wants appears.
However, Senju Tobirama has to first make twenty-eight hand seals to cast Water Dragon Ninjutsu, and then release Great Cold Energy.
"Given your casting speed just now, even if you cast Ice Release, its value isn't high, unless you can turn Ice Release into a Bloodline Limit, where it just comes out with a clap of your hands."
In Rosen's view, Senju Tobirama had an inherent advantage in developing Ice Release.
He originally had the qualification to use Ice Release, it just wasn't as fast as a Bloodline Limit.
So, his development of Ice Release also possessed advantages that others didn't.
Senju Tobirama fell into contemplation, then suddenly thought of something. The next moment, Senju Tobirama raised his palm, and a stream of Chakra appeared in his palm.
Immediately after, Senju Tobirama began to adjust the proportion of Chakra.
This guy isn't seriously thinking of completing the development of a Bloodline Limit this easily, is he?
Even if he's a Genius, it can't be this absurd, can it?
A Bloodline Limit cannot be developed so easily.
But to Rosen's astonishment, the Chakra in Senju Tobirama's palm gradually solidified into ice.
"Hiss… You succeeded?"
"I succeeded, yet it can't be considered a success." Senju Tobirama's face showed a look of triumph, clearly the face of someone who had already succeeded.
"Oh… Then congratulations." Rosen turned and walked away.
"Aren't you going to ask me how I did it?"
"I absolutely will not give you a chance to show off." Rosen detested Senju Tobirama's smug expression.
"Don't go! Hurry and ask me how I did it!" Senju Tobirama immediately grabbed Rosen.
At this moment, he really wanted to find someone to confide his thoughts to, or more accurately, to show off to someone.
"You wish." Unfortunately, Rosen had long seen through his intentions, so Rosen shook off Senju Tobirama and turned to leave.
"Don't you want to know why I said it succeeded yet didn't count as a success?"
"No."
Senju Tobirama tugged at him all the way, insisting that Rosen listen to his ideas.
Rosen wouldn't let him have his way, so eventually Senju Tobirama took the initiative to explain.
He hadn't developed the Ice Release Bloodline Limit.
A Bloodline Limit is the ultimate mental change of two attributes, ultimately etched into the Bloodline to be passed down as a Legacy.
What Senju Tobirama had just used was not a Bloodline Limit, but rather by adding Wind and Water Chakra, and then adding a third attribute, Great Cold Energy.
He directly used a simple and crude method to cast Ice Release.
Moreover, while the manifestation was Ice Release, the three attributes belonged to Bloodline Extinction.
"This method is considered a trick, but its power is much stronger than a Bloodline Limit. In the Land of Earth, it's said there's a guy named Onoki who mastered three Chakra nature transformations and called this ability Bloodline Extinction. What do you think of this Ninjutsu I've newly developed?"
"I know that Onoki. He named his Bloodline Extinction Dust Release. If it's about the range of destruction, you win. If it's about single-target destruction, Dust Release wins."
"I haven't developed it deeply yet, how do you know my single-target destructive power isn't as good as Dust Release?"
"Then tell me when you develop a skill with single-target damage exceeding Dust Release."
The Ice Release developed by Senju Tobirama could only be considered a pseudo-Bloodline Extinction.
Both Bloodline Limit and Bloodline Extinction possess the effect of Bloodline inheritance.
However, Senju Tobirama's was purely a Cursed Technique, not etched into his own Bloodline.
Nevertheless, his idea still gave Rosen a completely new perspective.
Since Senju Tobirama could combine Wind, Water, and Great Cold Energy to form a unique Ninjutsu.
Could he also develop a unique Ninjutsu using this idea?
Senju Tobirama immediately returned to his residence to further develop Ice Release.
Rosen also returned to his own residence; in fact, Rosen's living quarters were arranged next door to Senju Tobirama's, and he was also researching a completely new Ninjutsu.
Both of them could feel the fluctuations of Chakra and Qi coming from next door.
Solar terms are important factors that can trigger Chakra qualitative changes, just as when Wind and Water Chakra are mixed with Great Cold Energy, Ice Release is formed; this is like a chemical formula.
In other words, as long as the corresponding chemical formula is found, a completely new Chakra qualitative change can be obtained.
And in the scientific community, there's a saying: science is essentially a process of trial and error.
So, this process was not smooth. Randomly increasing or decreasing Chakra proportions could easily lead to accidents, such as explosions or tearing.
Compared to Rosen, Senju Tobirama next door was clearly much smoother.
He had already determined the proportions and formula, and now it was just a matter of applying this formula in practice.
Finally, on the second day, Rosen developed a formula ratio: 30% Wind attribute + 65% Fire attribute + 5% the awakening of the spirit, resulting in a stable, completely new attribute.
Rosen called this attribute Light attribute.
However, at present, only the Light attribute has been determined; there has been almost no further skill development.
Rosen thought of Kizaru Borsalino, one of the three Admirals in Pirate King, the owner of the Glint-Glint Fruit.
The characteristics of light are speed and extreme penetration. Following Kizaru's example, Rosen developed Flowing Light, Light Speed Kick, ama no murakumo, Yata Mirror, and Fire Tree Silver Flower.
As for elementalization, Rosen couldn't achieve it, as this was merely developing a type of energy, not a change within himself.
