Four crystals of different shapes emitted four different colors, and in the dazzling four-color light, the four crystals slowly floated from the palms of Zhuang Xiaoyuan's four people and began to converge towards the center.

When the four crystals of different shapes and colors are fitted together, a more dazzling light bursts out from them, no longer the previous four colors, but as if nothingness, as if nothing exists, but can make people feel the color of the existence of color.

I can't describe that kind of color, it seems to be transparent without any color, and it seems to be chaotic with all colors. In this indescribable color, the four crystals finally fused together, and a crystal clear four-leaf clover slowly suspended in the center of Zhuang Xiaoyuan's four people.

With the appearance of the four-leaf clover, that wonderful color began to spread around, enveloping the entire central city in an instant. The wonderful color seemed to feel Zhuang Xiaoyuan's intention to protect, and gradually formed a semi-circular protective ring to firmly protect the central city.

The black fog finally came, not only in the south but also in the east, when the northern city was destroyed by the black fog, the East China Sea city located in the east of the central city was also destroyed by the black fog, and no one in the East China Sea city even had time to escape, and all disappeared in the black fog.

The black mist that quickly diffused quickly came into contact with the protective ring of this wonderful color, and it was like an oil explosion with a few drops of water dripping into the hot oil. In an instant, the black fog enveloped the entire central city, but in the face of the four-leaf clover's protective ring, the black fog was completely blocked out and could not get close.

"Did we succeed?" Looking at the black mist that was blocked from the wonderful color, Wen Hui's eyes showed a hint of joy.

"I guess it's safe for now." With a hint of hesitation in her eyes, Feng Xiaoxuan looked at the wonderful colors around the central city that completely blocked the black fog from the outside, and frowned slightly with a hint of uncertainty in her tone.

"It's just a palliative, not a cure. Our side is temporarily blocked, but there are still four cities of Jiangnan, Xishu, Tianji and Diyan, if the black fog goes over there......" Also looking at the wonderful colors around him that blocked the black fog, Zhuang Xiaoyuan also frowned.

Unexpectedly, after the fusion of this four-leaf clover world crystal, it only created such an isolated protective shield, and did not erase all the demons in an instant as he imagined.

"Ah~ What is this, don't, don't."

"I'm going to be a monster, I'm going to be a monster. Don't. ”

"Ah~ Help, who will save me."

"Dad, don't, I don't want you to be a monster."

Just when Zhuang Xiaoyuan and the four of them were a little relieved because of the protective shield made of four-leaf clover crystal, and began to think about how to deal with the black fog demon outside, the city suddenly began to make noise.

Panic began to spread, and amid the frightened shouts and cries for help, a faint black mist began to appear on the bodies of many ordinary people one after another. With the appearance of the black mist, a trace of black began to slowly spread on them.

"What's going on? Why is this happening, haven't the World Crystals already protected us? "Seeing the civilians around me who are beginning to gradually deify. Feng Xiaoxuan's usual calm and gentleness on her face couldn't be maintained, revealing a trace of panic.

"Damn, has the crystal's power failed?" With a hint of anxiety in his eyes, Zhuang Xiaoyuan looked up at the four-leaf clover crystal, which was still exuding a wonderful light at this time.

"It's not working, they're slow to deify. But after all, it still didn't completely resist. Chu Miaomiao's steady voice came, but at this time, although her voice was steady, it was also much shorter than usual, and her heart was probably not calm, but she was the first to notice this change when she had been paying attention to the evil gods of civilians.

"In this way, is the ability of the world crystal not enough to completely resist the erosion of the black mist? What to do, we have nothing to do. The brows were tightly furrowed, and Wen Hui bit her lower lip tightly to show an unwilling expression.

"Why can't the World Crystal resist the invasion of the Black Mist? It's obviously a world crystal in the main world, and it can't be worse than the world of trials. Why is that? Frowning, Zhuang Xiaoyuan bit his nails and thought frantically, but he couldn't think of a reason or a way.

"Because you haven't fully brought out the true power of the World Crystal." A crisp voice with a hint of familiarity suddenly came from behind. Zhuang Xiaoyuan jumped up in shock.

Turning around and looking behind her, there was a girl with long straight black hair, purple eyes, white skin, a black hairband on her head, and a black and white dress, and the image of this girl made Zhuang Xiaoyuan even more surprised: "Xiao Meiyan?!"

"It's been a long time, Xiaohui, Xiaomeow and the first time we met, Sister Xiaoxuan." With a slight smile on his face, Zhuang Xiaoyan, who suddenly appeared behind Zhuang Xiaoyuan, bowed his knees to Feng Xiaoxuan and the three of them saluted and said hello, then looked at Zhuang Xiaoyuan and said, "You finally got the original appearance, Xiaoyuan."

"Are you Zhuang Xiaoyan?! Wait, did you say the original appearance, the appearance of Madoka Shikame? Is this what I originally looked like? It can't be that I'm the reincarnation of Madoka Shikame or something. Hearing what Zhuang Xiaoyan said to herself, Zhuang Xiaoyuan's attention was instantly shifted to her words.

"Well, if you think so, it's okay. The birth of the magical girl Madoka world itself is the reflection of our existence into a certain world. The corners of his mouth were slightly upturned, Zhuang Xiaoyan seemed to be very satisfied with Zhuang Xiaoyuan's surprised gaze at this time, nodded and replied directly.

"Our existence mirrors the world...... Who are we in your mouth, and what am I? With his brows furrowed slightly, Zhuang Xiaoyuan looked down at himself, looked up at Zhuang Xiaoyan and asked with a serious face.

"Madoka, what are you talking about? What, what, what? Isn't Madoka just Madoka? Hearing the conversation between Zhuang Xiaoyuan and Zhuang Xiaoyan, I don't know why, Wen Hui and the others felt that the distance between them and Zhuang Xiaoyuan was suddenly stretched away, as if Zhuang Xiaoyuan was about to leave them, so Wen Hui reached out and grabbed Zhuang Xiaoyuan's sleeve with some concern.

"Hehe, I can't tell you more. It doesn't make sense if you don't think about it yourself. I'm only two steps away, and I'm sure I'll be able to accomplish that soon. Shaking his head with a smile, Zhuang Xiaoyan refused to answer Zhuang Xiaoyuan's question.

"Well, do I need to find out on my own? Let's put this aside for now, you just said that we didn't activate the true power of the World Crystal, so how can we fully stimulate her power. Shaking his head, leaving more and more mysteries in his mind behind, Zhuang Xiaoyuan's face returned to his original seriousness, staring at Zhuang Xiaoyan and asking.

In the time when several people were talking to each other, the city had begun to become more and more chaotic, and many people with relatively weak constitutions had completely become evil gods. There are also many people who stopped breathing before they were completely deified in the pleading with relatives and friends, and were sent into eternal sleep by their relatives.
