He didn't really have to think much against Experimental Subject No. 1. Even though he was a Kage-level Shinobi, it shouldn't be a problem. He might even have to hold back as he didn't want to accidentally destroy the precious Sharingan.
Although it was only a three-tomoe Sharingan, obtaining it was very difficult.
Now, unlike before, Nagasawa wanted to improve the relationship between Konoha and Uchiha Clan.
He would not touch Uchiha's Sharingan, and neither would he let Orochimaru touch it.
If he wanted this experiment to produce results, Sharingan was indispensable.
He couldn't get Sharingan from Konoha, but there was one person who had some spare Sharingan in his hands, and that was Obito.
Those Sharingans were originally Madara's, but Obito was the successor chosen by Madara. After Madara died, he naturally inherited a lot of Madara's backup Sharingan.
Experimental Subject No. 1 flashed, constantly searching for Orochimaru's location in the base.
But before he could find the location of the surveillance room, he was first found by Nagasawa.
At this time, Nagasawa was wearing a different outfit from the one he saw last time. The last time, Nagasawa was dressed in the same outfit as Shinobi.
Today, Nagasawa was dressed like a researcher. He was wearing a loose white coat, there was no pouch on his waist, and he didn't bring any weapons either.
Seeing Nagasawa, Experimental Subject No. 1 backpedaled subconsciously. He still remembered the Nagasawa's terrifying attack at Root's base that day.
However, seeing that Nagasawa was empty-handed and did not have any weapons on him, Experimental Subject No. 1 was slightly relieved.
It was obvious that Nagasawa looked down on him and thought that he could beat him without weapons.
Experimental Subject No. 1 was happy instead of angry since he was being underestimated. With this, his chances of winning would be higher.
At this time, Experimental Subject No. 1 felt that his chances of winning were very high.
Since Orochimaru had made some modifications to his body, he was now much stronger. His two eyes could also see through the opponent's movements.
A swordsman like Nagasawa underestimated him too much by not even bringing a sword.
Under such circumstances, his victory was inevitable.
"Earth Release: Earth Dragon Bullet!" Experimental Subject No. 1 quickly formed a hand seal to use his best Ninjutsu.
The dragon head made of mud and stone continuously shot mud bullets at Nagasawa.
Nagasawa thought about it and felt that there was no need to waste time. He might as well end this quickly.
Instead of dodging, Nagasawa kept walking as the mud bullets were heading toward him.
"Shigan!"
Nagasawa focuse a large amount of Chakra into his index finger, then transformed it into lightning attribute chakra as he thrust it toward Experimental Subject No. 1.
The mud bullets bombardment couldn't even slow down Nagasawa as he cut them all down.
With Lightning Release granting him speed on top of Total Concentration Breathing, Nagasawa practically arrived in front of Experimental Subject No. 1 in an instant.
Siu!
Zizi, Zizi!!
Experimental Subject No. 1's eyes widened before he spurted out a mouthful of blood. He felt the lightning electrocuting and looked at Nagasawa in disbelief.
"How!"
He had three-tomoe Sharingan, but he was actually instantly killed without being able see Nagasawa's movements clearly.
Before Experimental Subject No. 1 figured out the answer, Nagasawa immediately knocked him out.
Nagasawa then looked at Orochimaru, who was slowly walking over.
"As expected of Nagasawa-san. Maybe only Sarutobi-Sensei can fight you evenly in Konoha." Orochimaru said with a smile as he walked out of the dark.
Unlike last time, Nagasawa did not use his sword, but the power that Nagasawa displayed this time still surprised Orochimaru.
With Nagasawa's speed just now, Orochimaru didn't think he could dodge Nagasawa's attack with his reaction speed alone.
Although Nagasawa had only fought in front of him twice, Orochimaru found that Nagasawa was a Shinobi with no obvious shortcomings.
With a sword, he could send out a terrifying Flame slash attack, which was very powerful and could be used as a long-range attack.
At close range, even if Nagasawa didn't use a sword, he could still use Ninjutsu, similar to that of a Raikage, as it was not only fast but also powerful.
He just didn't know how well Nagasawa would do against Genjutsu.
Against someone like Nagasawa, who could fight in both close combat and long-range combat, Orochimaru felt that only the Third Hokage had a chance to defeat Nagasawa in Konoha.
Just like Nagasawa, the Third Hokage could use Five Nature Types to bombard the opponent from afar and use Enma's staff mode to deal with opponents at a close range.
Orochimaru even felt that Minato might not be able to defeat Nagasawa, as even though his speed was very fast, his attack was monotonous. He would only use Rasengan.
"You're exaggerating, Orochimaru. Experimental Subject No. 1 is just too weak." Nagasawa was a little modest.
Both of them smiled and quickly left the abandoned base with Experimental Subject No. 1 in tow. However, before leaving, Orochimaru completely destroyed the entire base.
......
It was Monday again, the day when Nagasawa received points. After thinking about it, he spent 120,000 points to raise Whitebeard's fusion rate to 66%.
At this time, he still had 40,000 points left, and he could raise the fusion rate a little bit more, but he thought raising the fusion rate by a little bit wouldn't do much. Points were very useful. In addition to increasing the fusion rate, it was also useful for other things.
Nagasawa decided to save the remaining 40,000 points in case something unexpected happen.
After all, increasing the fusion rate by 2% wouldn't do much.
However, after careful calculation, Nagasawa felt that he was still short on points. He might not be able to max out Whitebeard's fusion rate before the Nine-Tailed Demon Fox's attack.
"Should I cosplay again?" Nagasawa thought of another method to increase the fusion rate.
However, the night of the Nine-Tailed Demon Fox's attack wasn't that far off. He had to stay in Konoha to prevent any accidents.
He could indeed leave a Shadow Clone, and it should be strong enough. The problem was retaining that Shadow Clone.
The more Shadow Clones he made, the more exhausting it'd be in the long term.
However, Nagasawa immediately thought of a way. If he had enough reserves, he should be able to maintain the Shadow Clones for a while.
Under normal circumstances, Shadow Clone didn't have as much Chakra, but there was a technique that could solve this problem, and that was Tsunade's Strength of a Hundred Seal.
Strength of a Hundred Seal could accumulate Chakra on the user's forehead, and the user could release it whenever they wanted with Yin Seal: Release.
If he learned it, he could allocate more Chakra into his Shadow Clones, and when they were short on Chakra, it could use Yin Seal: Release to get the accumulated Chakra so that they could last longer.
Now the only thing that Nagasawa was worried about was, whether Tsunade would teach him Strength of a Hundred Seal or not.
