Chojusen still had his second stage Fiendgod Eyes activated. Moreover, now that his time law principles were on par with his space law principles, the effects of the second stage eyes, could now work on Kaguya. He covered his hands with Chaos Law Principles and shoved them into Kaguya's robe and pulled out Black Zetsu. When the two were separated, Chojusen noticed that Kaguya took a terrible blow to her soul; she almost blacked out.
Somehow she stayed conscious, even when such a large part of her soul was cut off. She looked at Chojusen with gratitude in her eyes and said "Thank you for freeing me of that curse… And I'm truly sorry for all the pain and suffering I caused..."
"Curse?"
"Do you know how I became the progenitor of chakra?"
"No."
"Where do I begin? Let's start off with the Otsutsuki Clan..."
Kaguya then went on to tell Chojusen a wild but true story of how she came to this planet and defied her Clan's taboo of eating a Divinity Tree's fruit. The story ended with Kaguya explaining that the moment she ate the chakra fruit of the Divinity Tree, she had her entire body overhauled. She gained tremendous powers that were eventually spread out to the ninjas of mankind, but while her body gained the god-like powers of chakra, her mind was overloaded with emotions and in that battle, negativity won, resulting in her manifesting Black Zetsu as a part of her will, to keep some piece of her sanity.
When she finished her story, Chojusen forgave her as it hadn't really been her fault; the guilt and regret that she emanated, towered over her figure when Chojusen observed her with Essence Sensing. However, Kaguya felt like she had caused enough suffering and pain to the this world, so she elected to commit suicide. She used what little chakra she still possessed, and made a bone knife emerge from her palm.
Right as she was about to kill herself, Chojusen caught her arm and said "Don't deal with regret like a coward and end your life. Atone for you past mistakes and improve the quality of the world with your strength." The smile on his face was dazzling to this woman who thought she lost everything.
Chojusen didn't notice it, but a certain light shined on her eyes as she heard his words. Chojusen helped her up and began to help her recover stamina and energy, but because she was well into the Immortal Rank, even with his powers, her recovery might take a while.
As she was recovering, she teleported with Chojusen's help back to where the Divinity Tree was grounded and released all the people she captured. As the ninjas broke free from the Divinity Tree's grasp, they prepared for battle only to find Chojusen healing the enemy.
Naruto and his clones went on to explain what was happening and calmed everybody down. The ninjas that came to get on Chojusen's good side started sweating bullets as they now had no way to show their sincerity; if only they knew that Chojusen had already read their emotions when they were released.
When Chojusen healed Kaguya back to the point where she could move between dimensions, she transported everyone out to the world outside her dimension. As Chojusen was thinking of what to do now, he came up with a devious thought to scam the system. He laughed, maniacally and with no apparent reason causing the people around him to think he went insane.
In his hands there still existed Black Zetsu, or Kaguya's evil will personified. Since it was still technically a part of Kaguya, the bonus mission should be complete if he sealed Black Zetsu away. He quickly called over Sasuke and Naruto and asked them to give him some of their Six Path Chakra. The two he called over he no idea what his plan was, but they had just seen him fight and they didn't want to get on his bad side, so they complied.
Chojusen created a Dimensional Seal with his right hand and a cube of metal in his left hand. The seal was of a much high quality than when he used it on the Shukaku as the space and time law principles directly made up the kanji for "empty." Naruto added a bit of his light golden Six Paths energy into the seal, while Sasuke added a dark golden energy.
Chojusen then shoved Black Zetsu — which had been molded into a ball by now — into his seal and then into the metal cube. With the seal complete, Chojusen received a most satisfying message from the system.

"Ooh, what's this world shard?"
[Well, It's hard to explain, but to put it simply, it's the crystallized essence of a piece of a world. Anyways, it doesn't matter what it is, so much what it can do. Right now, if you used the World Law Shard, you wouldn't get nearly as many benefits as you would with a bit of patience.]
"Oh? A secret? Due tell, oh kind and perfect system-kun~" At this point Chojusen wouldn't mind kissing the system's non-existent feet after being so generously rewarded.
[Stop that. Its… creepy. You are almost at the height of power this world can offer, so when he move to a higher world, you can use the world law shard to instantly comprehend a piece of that higher worlds laws. Furthermore, you will be able to retain a bit more of you power, when you go to make the transition.]
"I'll lose my powers when I ascend into a higher world?"
[Technically, no, as your true body won't be going. Rather, you will start all your journeys in higher worlds by sending an avatar instead.]
"What? Why?"
[Higher worlds don't exactly accept foreign entities easily, ok? If an Immortal were to just show up while being able to disregard to world laws, who know how messed up the multiverse would be. As a way to prevent that from happening, universes use eradication laws to destroy foreign entities that break the cosmic law. The only way to not get destroyed when ascending, is to use an avatar to adapt to the world's laws before the true body decides to make an appearance.]
"Aw, that sucks… So does that mean that I have to start all over again from scratch?"
[Do you not know what an avatar is? Your true body isn't going to higher worlds until the avatar reaches your level. So, no. You will be here in this world with all your powers until your avatar succeeds in training in another world.]
Chojusen returned back to the reality as everyone was waiting for him to express what they would do now. Chojusen looked at the crowd of legendary ninjas and said "Well, let's go home."
He created a couple dimensional gates, one for each of the main hidden villages of the elemental nations. Chojusen was a bit surprised that no one used the dimensional gate that went to the Hidden Sand village in the Land of Wind; the only ninjas that might have used it were Gaara and his father and they both chose to head back to the hidden leaf to help repair the village.
Chojusen waited for all the Hidden Leaf ninjas to leave before telling the remaining ninjas of the Hidden Cloud, Hidden Stone, and Hidden Mist that he would look for them later... The Ninjas were glad that the god before them didn't decide to wipe them out then and there and many of the powerhouses made boastful promises that were borderline impossible to accomplish in reality.
Chojusen let them off the hook, but he would not give them a completely free pass. No, these ninjas would have to "donate" a generous sum of money to the hidden leaf if they wanted to make amends.
When all the remaining ninjas left, Kaguya was the only one left with Chojusen. Chojusen looked at her and said "What do you plan on doing now?"
"I think I'll follow you advice and try to make the world a better place… without using force, threats, or violence. But I don't have a place to live..."
Chojusen didn't need to be an Immortal to know that she was lying through her teeth and only wanted him to offer her a place in the Hidden Leaf, so he said "I can give you a place to stay in the Hidden Leaf." He was sure that with all the merits he had earn today, he could ask Minato for another favor.
Kaguya excitedly thanked Chojusen for offering her a place in his village. Chojusen was amused watching this woman that had godly powers and was behaving with heaven defying arrogance and pride just a couple minutes ago, now thank him as if she was some teenage girl.
Chojusen teleported back to the village with Kaguya, he appeared right in front of Minato, who had just finished giving some people orders to start repairing the part of the village that Pain destroyed. Minato was a bit surprised to see Kaguya stand so respectfully behind CHojusen, but he was more surprised by Chojusen's request.
"You want to keep her in the village?"
"Yes?"
"... Didn't she almost end the world?"
"Yeah, but not really. It was a curse thing that I've already remedied."
"Well, whatever, it's your choice. But she is your responsibility..."
"Yeah, yeah. It's not like anyone else can stop her right now..."
