Save Ace, Kill Teach

Obito looked at Musashi indifferently, and Musashi's vision instantly blurred, and he fell into Obito's Genjutsu.

"Musashi!" Nagasawa used a bit of the Color of Supreme King Haki on Musashi. 

The two forces collided, and Musashi instantly snapped into his senses. Seeing that his pops was still standing there, he knew that he had just fallen into a Genjutsu. 

After all, he suddenly saw Obito kill his pops just now.

"Musashi, you should go." Nagasawa turned his back to Musashi, blocking Obito's line of sight with his body, and looked at Obito. The powerful Color of Supreme King Haki was also directed against Obito.

Obito frowned. It seemed that Whitebeard was ready to fight him to the end.

Nagasawa grabbed Musashi and threw him far away.

Pain took a few steps back and said expressionlessly, "He killed Hanzo and avenged Yahiko. I won't do anything to him."

After saying that, Nagato levitated and left. He had other things to deal with.

If the masked man couldn't get rid of an old man who nearly died, he didn't deserve to cooperate with him in the first place. 

What kind of Madara Uchiha would lose against an injured old man?

Obito nodded. It was not strange for Nagato to do this. The agreement between the two was that Obito helped to kill Hanzo. Once Obito did, he'd also help Obito with his plan.

But this time, it was obvious that Obito did not do much. Nagasawa basically killed Hanzo by himself. Nagato did not help Nagasawa out of courtesy. 

"Wood Release: Cutting technique!"

Obito stretched out his left hand, and suddenly a lot of sharp wooden spikes came out of his hand and bombarded Nagasawa.

Nagasawa clenched his fist and fiercely threw a punch, breaking the wooden spikes.

The powerful wind from the impact of Nagasawa's punch alone even pushed Obito back pretty far.

This punch completely eliminated ​​Obito's idea of fighting Nagasawa head-on.

It also made Obito even more determined to kill Nagasawa. Since he had already offended Whitebeard, Whitebeard wouldn't let him walk away.

"Fire Release: Great Fireball Technique!"

Obito quickly used Great Fireball Technique. A large fireball that was several times taller than a person instantly appeared. Then Obito used Wind Release right after,  and the fire instantly became bigger as a result.

Nagasawa laughed and did not retreat. He raised Murakumogiri and split the fireball.

"You fake bastard, I won't let you hurt my son." After that, Nagasawa raised Murakumogiri, enveloping its blade with a quake bubble.

Obito instantly felt that he was in danger.

However, he did not immediately use Kamui. Instead, he provoked, "Try me!"

At this time, Nagasawa was already near his limit. If he used too much strength, he would definitely die.

Obito believed that Nagasawa would definitely use the punch that had destroyed the entire Amegakure earlier to take him down.

However, Obito was certain that Nagasawa did not know was that his Kamui could make himself intangible in addition to the teleportation ability it had.

As Obito had guessed, a quake bubble enveloped Nagasawa's left hand. It was as if the space itself was about to be torn apart.

Crack! Crack!

The apocalyptic scene from before happened once again. Cracks appeared one after another, even in the sky, and the ground was also shaking violently. The huge cracks that were already there before instantly grew bigger, and some of them were already so deep that one couldn't see the bottom.

Rumble!!

The power of vibration erupted in an instant, and a loud noise resounded throughout the battlefield.

A powerful shockwave spread out in all directions. Under this powerful shockwave, a large chunk of the ground was uprooted.

Seeing such a terrifying attack, Obito directly used Kamui to turn his body intangible, avoiding this devastating attack.

After the attack, Obito canceled Kamui and began to check the situation.

At this time, there was no ground that remained intact. There were many deep cracks and massive holes.

Obito searched carefully, but he could not find any trace of Whitebeard. There was a big crack even at the place where Hanzo's body lay, and Hanzo's body was also missing.

"Did he fall into the crack?" Obito guessed.

He searched again carefully but did not find anything, so he left.

He assumed that Whitebeard should be dead.

After launching such a powerful attack with such a serious injury, Whitebeard should die even if he left him alone.

Whitebeard was already an old man on top of that.

After sensing that Obito had left, Nagasawa came out with Hanzo's corpse.

Just now, he was hiding in one of the deep holes, and even used Selfless State to hide his presence.

The reason why he brought Hanzo down with him out of consideration.

He didn't want Hanzo to be resurrected with the Impure World Reincarnation Technique, so he sealed Hanzo's corpse with a sealing scroll before leaving Amegakure.

...

After returning to Konoha, Nagasawa first took a bath and then checked the fusion rate.

During the Summit War of Marineford, Whitebeard stayed behind and eventually died protecting his sons, which Nagasawa re-enacted by helping Musashi escape before "dying".

The fusion rate increased once again all the way to 88%, just 2% short from 90%, which allowed him to take on the challenge mission.

Nagasawa immediately spent 60.000 points to increase the fusion rate to 90%.

The system notification quickly echoed in his mind.

[The fusion rate reached 90%. Complete the Challenge Mission !]

[Edward Newgate's challenge: Save Ace in Summit War of Marineford, kill Blackbeard, and then retreat with all Whitebeard pirates. Completion reward: 10% fusion rate. ]

Nagasawa was not surprised when he saw Whitebeard's challenge mission. He had already predicted it a long time ago.

However, Nagasawa did not rashly start. Although the injuries he received during the challenge mission wouldn't be carried on when he was back to his world, it'd require points for another try. In addition, it turned out to be quite expensive as he needed 35,000 points for one try.

Raising Whitebeard's fusion rate was expensive might be part of it, too. After all, Yoriichi Tsugikuni's challenge mission didn't require as many points because it didn't require that many points too to raise Yoriichi Tsugikuni's fusion rate.

There were too many skilled combatants in the Summit War of Marineford, such as Garp, Sengoku, and the three Admirals. None of them were an easy opponent.

With Ninjutsu as the element of surprise, Sun Breathing's power, and Whitebeard's own strength, it might not be a problem to defeat one of them, but five was certainly difficult.

Nagasawa planned to wait until he got the third template. At present, the Prosperity Value had reached 1930. It was now the end of July. If he worked hard, he should be able to unlock the third template before the Nine-Tailed Demon Fox's attack.

Once he got it, he'd check if there was any suitable template to use for Whitebeard's challenge mission.
