Xiao Nan thought carefully and then said, "You killed Danzo."
"Cough... that doesn't count. Danzo wasn't human, so I haven't killed anyone from Konoha," Li Xing coughed dryly, forcing an excuse for himself.
"Why did you say before that this world would never have peace? What do you know?" Xiao Nan asked the question she most wanted to know. Even knowing Li Xing's power, Xiao Nan still firmly believed that peace would come.
"That's a long story. Let's find a place to talk!" After saying that, Li Xing picked up Xiao Nan and entered the Infinite Domain, arriving in the room where Xiao Nan had slept before.
He placed Xiao Nan on the bed, pulled over a chair to sit, and poured a cup of tea for Xiao Nan.
"Peace can be understood in many ways. For example, the war between the Akatsuki and the Five Great Nations will end and enter a state of peace. But within this peace, some people will still be vying for power, such as killing others for money, or fighting over trivial matters."
"What you and Nagato think of is world peace. You haven't seen the trivial things. Some children who haven't grown up fight over toys, and their peace is broken. When their parents fight or even kill each other to stand up for their children, then the peace of two families is broken."
"And when people from two countries are at war, world peace is broken. In the final analysis, peace will never exist; there will only be struggle."
"As long as there is life, there can never be eternal peace. Wolves eat sheep, sheep eat grass, and grass competes with other grass for land and nutrients. In such a food chain environment, how can the peace you speak of exist?"
Li Xing's words seemed reasonable, but from a human perspective, they were not. As humans, they naturally prioritized their own kind. Li Xing was viewing things from the perspective of the Heavenly Dao.
"Then don't bother with those flowers and grass. For the struggles between people, there are laws and regulations of the country and village. But for world peace, there is no one to maintain it. Nagato and Yahiko's dream is not wrong; your statement is the one that is wrong."
Xiao Nan calmly looked at Li Xing and retorted, her eyes filled with determination, not intimidated by Li Xing's strength.
Li Xing slowly took a sip of tea. "Even if the peace you speak of truly comes, do you understand what humanity will become?"
"I don't know. I only know that in such a world, there will no longer be orphaned children because of war, nor will there be people stealing for a bite to eat. No one will have to fear losing their lives due to conflict. What is wrong with such a world?" Xiao Nan couldn't understand, what was bad about such a world?
Li Xing extended an index finger and shook it in front of Xiao Nan. "You've overlooked a crucial point, which is growth. Humans are evolving beings. To protect themselves, humans learned to make weapons. To protect their kin, humans established tribes."
"Eventually, they formed countries and villages. When a country develops new technology, it will break the balance between countries. Other countries will feel pressured. To avoid being annihilated, they will strive to progress. Science is the greatest technology for human progress."
"What you are talking about is merely the peace of this world. In times of peace, humans have no competition, no sense of pressure. Then, if one day, strong individuals from other worlds arrive on this planet with powerful weapons, humanity will only be annihilated. In a state of comfort, humans will not grow. This world needs competition; pressure is the best way for people to become stronger."
"In summary, do you understand? In short, I don't hope for complete world peace. People need opponents to motivate themselves to become stronger. The Warring States period and the current Five Great Nations era are the best comparisons."
Xiao Nan fell silent after listening. It was indeed as Li Xing said; when the world became peaceful, people would become lazy. If there were truly people from other worlds, and this world was invaded, humanity would only face annihilation.
"How do you know there will definitely be people from other worlds? What if those things don't exist?" Xiao Nan looked at Li Xing, her eyes no longer as firm as before. At this moment, Xiao Nan had a bold guess in her heart.
Hearing Xiao Nan's question, Li Xing smiled. "Do you know whose child the Sage of Six Paths was? His mother was called Kaguya Otsutsuki, the Goddess of the Moon worshipped by humans in ancient times. Legend has it that the Goddess of the Moon became pregnant with the blessings of the people. Finally, Kaguya gave birth to two children, one named Hagoromo Otsutsuki, and the other named Hamura Otsutsuki."
"And Hagoromo Otsutsuki is the name of the Sage of Six Paths. His mother, Kaguya Otsutsuki, came from another planet. She was not a native resident of this world. So, do I need to say whether there are other worlds?"
Xiao Nan thought for a moment. The ninja world seemed to have such a folk legend. She had heard Jiraiya mention it before, and Jiraiya had also said that Nagato might be the reincarnation of the Sage of Six Paths.
"Those are just legends. These things might have been fabricated by people."
Seeing that Xiao Nan was still unwilling to believe, Li Xing snapped his fingers and projected images of him fighting demons in his previous world, as well as various battle scenes from the Demon Slayer Corps.
"Do you know demons? They are the demon slayer swordsmen responsible for eliminating these man-eating monsters. And I am one of them. These are my experiences in my previous world. If you don't believe in Kaguya Otsutsuki, then I am sitting in front of you now. Do you think I am a folk legend?"
Xiao Nan looked at the man-eating scenes and was shocked. "Is this really another world? Then you came from another world?"
Li Xing walked up to Xiao Nan, folded another rose with paper, and handed it to Xiao Nan. "Let me reintroduce myself. My name is Li Xing, and I am a traveler of the multiverse. Would you be willing to travel with me?"
Xiao Nan was silent for a long time, then slowly reached out towards the rose in Li Xing's hand. "Actually, I already guessed you were from another world just now."
"I am willing to accompany you on your travels!"
Xiao Nan took the rose, removed her lip piercing, and replaced the flower on her head with the rose folded by Li Xing, symbolizing that she would let go of the past and begin a new life.
"Wonderful! Come, give me a hug!" Li Xing opened his arms, wanting to hug Xiao Nan.
However, Xiao Nan pointed at Anko on Li Xing's back. "Then who is the woman on your back? Is she also a woman you tricked?"
Li Xing almost forgot about Anko. He immediately put Anko down. "She is my captive, a special jōnin from Konoha, Anko Mitarashi."
Xiao Nan suddenly laughed. This made Li Xing stare in amazement. He had been in the Akatsuki organization for so long, and he had never seen Xiao Nan smile before.
Suddenly, Xiao Nan hugged Li Xing. "Before I travel with you, I will join the Allied Shinobi Forces to stop Madara's Infinite Tsukuyomi plan. I want to see the world after the war. Also, the rainbow and clouds from before, were you confessing to me?"
Li Xing placed Xiao Nan on the bed. "As you wish. I still have some time to stay in this world. As for the rainbow and clouds just now, do you like them?"
Xiao Nan suddenly hugged Li Xing's neck and pulled him onto the bed, kissing him.
"I like them..."
...
(I can't turn back now. I've gone further and further down the path of having a harem. By the time I realized it, there were already many. So I will go all the way to the end.)
