The rag picking sister turned out to be a weapon refiner

"You still have the nerve to say that. If you had come back sooner, we wouldn't be in this situation..." Qingyue's words were filled with a hint of blame, but more of helplessness and relief. She looked at Hu Xingtong tenderly, as if she saw the sister who had sacrificed herself to save her.

"I've failed everyone's expectations. If I hadn't been in seclusion for so long, perhaps none of this would have happened." Si Xu's voice was low, filled with self-blame. He looked up into the distance, his eyes gleaming with resignation. "As much as I hate Zuo Ying, I'll never have the chance to seek revenge. Now I can only be a bystander, watching the chaos of the immortal cultivation world, no longer qualified to intervene."

"Xingxing, accept the mission." The system reminded him, and then a voice announced the mission in Hu Xingtong's mind: "Detected that the host has triggered a hidden mission. Please complete the 'Good vs. Evil' mission and understand the reason why Sixu remains in the world before officially starting the mission. Time limit: one month."

"A time-limited mission?" Hu Xingtong had never seen a time-limited mission before, so he couldn't help but feel strange and confirmed it again and again.

[Yes, you need to find out from Sixu's subsequent conversation why he set up the square formation to block Qingyue. Aren't you curious? It's obvious that the two of them don't have any deep hatred, but Sixu set up a square formation to prevent Qingyue from entering, just to hide the location of the hut. This is very strange.]

Hu Xingtong nodded in agreement upon hearing this, then turned to look at Sixu and Qingyue and asked, "Grandmaster, Senior Qingyue, I'm curious. Since you don't have any deep hatred and have a common enemy, why did you set up a square formation and not let Senior Qingyue find it?"

Hearing this, Si Xu looked towards Hu Xingtong in surprise, lost in thought at the all-too-familiar features. It wasn't until Qingyue unleashed a chill towards him in a sullen manner that Si Xu came to his senses. His empty eyes gradually regained their spirit, and as he looked at Qingyue's dissatisfied expression, he asked with concern, "Qingyue, have you felt any discomfort in your heart lately? Or have you felt unwell all over?"

Qingyue didn't understand why, but she always felt that there was something behind his words. Thinking about the origin of her heart, she felt a little nervous. She couldn't figure out the reason, so she could only answer in a trembling voice: "I feel a little uncomfortable, and it hurts from time to time. I feel uncomfortable every time I enter here." Qingyue covered the position of her heart, and the flesh and blood heart belonging to Zijing was beating.

The hearts of the Chunzhi Demon and the Xueyue Demon are different. The Xueyue Demon has a body of snow and a heart of glass, while the Chunzhi Demon has a heart of flesh and blood, a delicate heart. So when Qingyue's heart was taken away by Zuo Ying, only Zijing's heart could match it. When Qingyue learned that her heart was replaced by Zijing with the help of Sixu, she also complained. But when she heard Sixu say at the time that Zijing would not live long and hoped to exchange his delicate heart for Qingyue's survival before his death, she couldn't bear to complain.

She thought that even if Zijing and Sixu were in love, she was still her favorite sister.

"That's it. I think this heart now belongs to you completely. Maybe in the near future, we can wait here for their return." Si Xu smiled, his face full of satisfaction, and there was a hint of pity when he looked at Hu Xingtong again.

"I don't understand. The four-sided formation created by our master is centered around the Three Seasons Demon, and Senior Qingyue's glacier is the death gate. This is in itself a means of wasting remaining energy." Han Qianyu asked the question in her heart. Si Xu was also very patient and explained, "This story has to start from after that battle..."

After Zijing exchanged his heart with Qingyue, he was rapidly losing his life. Sixu didn't understand that although he came late, he wouldn't let Zou Ying take away the most important things of the three monsters without anyone noticing. He walked forward slowly and stretched out his hand to send Zijing back to the hut. However, just as he stretched out his hand to touch Zijing, the light came down again. Sixu was angry. If it weren't for this light, perhaps the four monsters would be fine, and perhaps Zou Ying would also die on the spot. There would be no chance of escape.

The source of everything is because of this light, and the cause of this light is myself, because I want to break through the limits of heaven and earth and reach the level of incarnation. If I don’t yearn for strength so much, will everything return to the source?

Si Xu hated himself and the owner of the light, but he could not resist and could only follow the guidance of the light and enter the door. Of course, he would not sit still and wait for death. He chose to exchange and use the thing he longed for most in exchange for an opportunity.

The Four Seasons Demon was born in the four seasons of nature. He is a spiritual demon born and raised by nature, and is favored by the great way of heaven and earth. Therefore, he got this opportunity, but the price he paid for this opportunity is needless to say.

So he was able to leave behind such an incarnation, and using his years of research and knowledge, he collected treasures of rare materials in the world, and set up a square array in this small house. On the surface, the four sides of the square array are headed by spring, summer, and autumn, and winter is the gate of death. However, only Si Xu knows that he is the most critical point in the eye of the array. He uses his own talent and luck as the line, and the winter gate of death as a deception. With the help of the special geographical environment of Hantan and Hanlu Mountain, he draws the energy of heaven and earth, and continuously gathers the elemental energy in the four directions of spring, summer, and autumn.

The reason why Qingyue was not allowed to enter the hut was entirely because Sixu needed someone to guard this secret realm. At the same time, it was also because Qingyue possessed Zijing's exquisite heart. In order to ensure Zijing's smooth resurrection, Sixu had no choice but to conceal the truth from Qingyue and create an illusion of sealing and harming the three demons for Qingyue, so that she had been guarding here for a hundred years and hiding her tracks for a month after Qingyue woke up.

It took nearly a hundred years to gradually digest the spirits of the Cold Demon and the Flame Demon. The last step required the destined person to take action personally. The existence of this destined person was also the top priority in the transaction. Only that destined person could break the formation, thereby dissipating the last vitality of the three demons, causing the three demons to dissipate in this life, and allowing the three demons to return to their birthplaces and be reborn.

Having said this, Si Xu looked at Hu Xingtong and finally explained the doubts in her heart: "I can't tell you why you look so much like Zi Jing, but I can tell you that you are not her and she is not you. There is not even any reincarnation relationship between you, but there is indeed a superficial causal line between you. However, all of this will only be known when you arrive. So, keep going, this place does not belong to you."

It doesn't belong to me...

Hu Xingtong carefully recalled Si Xu's words. She thought that Si Xu must have seen something in that light, and must understand the purpose of his coming to this world. Perhaps this world has long known about my arrival, or perhaps my arrival is the predetermined trajectory of fate.

She looked up at the sky above her head, and for the first time she felt that she was just a member of the vast universe, a small and ordinary existence in this world. Even though she knew that this world was not real, she was still curious about what it was like outside the sky, and she was still curious about the principles of the world's structure. Just like Einstein and those scientists who wanted to pursue the truth in the world, she was very curious about what the so-called truth of this world that was inextricably linked to her was.

While thinking, everyone only felt the spiritual fluctuations floating in the air and a trace of leaked spiritual energy, and they all looked at Hu Xingtong who was looking up at the sky.

There were relief and sighs, surprises and accidents. Only Qingyue and Sixu had deep eyes, as if they were looking at others through Hu Xingtong.

Just because of Si Xu's words, Hu Xingtong's state of mind improved, and the state of her surroundings could not even keep up with her state of mind, and could only be slightly disturbed.

[Congratulations to the host for completing the prerequisite task, and be rewarded with a hidden memory.]

The next moment, a white light poured into Hu Xingtong's mind from the system space. In a trance, Hu Xingtong saw a dim space. A person was sitting in front of a computer desk, typing on the keyboard. The light from the computer shone through his face. Hu Xingtong felt that the long face was particularly familiar, but he could not remember where he had seen it.

There were several drafts on the table, which were sketches of some task scenery. They looked very sloppy and the picture ended abruptly. There was only this not very specific picture, but it made Hu Xingtong confused.

"Whose memory is this?"

[This system doesn't know, but you can continue to complete the mission. I should have other memories for you later. These are also the things I found from you, fragmented and seemingly related to the origin of this small world.]
