When Xu Ai returns to City B, there is no need to worry. The appointment with Mr. Xiang is at dinner. There is plenty of time, let alone Mr. Xiang and others are in harmony with Mr. Xiang Nuan.

Xiang Nuan took out the backpack, took out the jewelry inside, put the keys and jewelry together to put them away, but when she saw two things together, something flashed in Xiang Nuan's mind, looking at the keys and then the jewelry. She suddenly held the jewelry and the keys and asked Xu Ai, "Do you think this set of jewelry was taken out of the box?"

Xu Ai was stunned and said to the truth: "Not sure, but I guess the possibility is not high. Although I didn't say it clearly, the box should be able to be opened once according to the meaning of the book."

Xiang Nuan thought of the rebirth of some fantasy effect of the box, and frowned. Why did she feel that things are becoming more and more unreal? Rebirth? What is rebirth? How could it be rebirth? But things seem to be related to jewelry, and she always feels that the jewelry has something to do with the key. Since she thinks so, she thinks about it. Maybe she can really find a way to combine jewelry into one.

Moreover, things have to be solved, but when Xiang Nuan thinks of this, he started to study jewelry again.

When Xu Ai saw that she was thinking about it, she sat beside her and studied the pattern on the key. The ones she saw in the book were still very different from the real thing. He wanted to see if the pattern had any special meaning.

Now he is very interested in the Hua family. What kind of family is the Hua family? Why is it capable of hiding for thousands of years and not exposed? Why do they shoulder the responsibility of protecting the Dragon Kingdom? What happened to the Dragon Kingdom a thousand years ago? And who gave them the responsibility to the Hua family? Is the Hua family really that mysterious?

Now that I think about it, each of them is a secret, and it is a secret that cannot be solved. But he was not convinced. Since there were clues, how could it not be solved?

Both of them were equally persistent and focused on their research.

Xu Ai found paper and pen to draw the pattern and studied it carefully, especially the pattern under the lock, which he could not see in the book.

Xiang Nuan was inspired by the key and the pattern on the box, so she thought whether this set of jewelry was originally a pattern, and it needed this pattern to be put together. This pattern may be related to the pattern on the box, so she tried it with the pattern on the box first.

The two of them were too attentive, and time passed quickly. After trying it over and over again, Xiang Nuan said in surprise, "Xu Ai, hurry up and take a look, I'll combine it."

When Xu Ai looked over after hearing this, he saw Xiang Nuan connect a section of the necklace to the same pattern as the pattern on the box. However, this pattern is the same as the pattern around the lock, not the pattern around the box.

"Can other places be connected?" Xu Ai asked in surprise. Xiang Nuan just put a small section of one end of the necklace together, and did not put it together with other jewelry.

Xiang Nuan shook his head, "No, I tried it many times. Only this part of the necklace can be connected together."

Xu Ai took it and looked at it. He found that the pattern around the lock piece was exactly the same. He suddenly remembered the other objects in the book that his grandfather showed him, and said almost in unison with Xiang Nuan, "The patterns on the things in that book are for connecting jewelry."

Xiang Nuan said in surprise, "Draw the pattern quickly and I'll try it."

Xu Ai looked at Xiang Nuan with joy and said annoyedly, "The pattern connecting the jewelry should be the same as this one, the pattern of the key parts. There are no pictures of the key parts in the book. What you can see is the same as the pattern around the box, so I can recognize it at a glance."

When Xiang Nuan heard this, her face suddenly collapsed and she became depressed. She thought she could finally combine jewelry into one. She was excited and poured a basin of cold water down, making her heart feel cold.

She did not doubt Xu Ai hid her own private parts. If Xu Ai really had selfish intentions, she should be anxious to let her put the jewelry together. What she thought was that if the jewelry was combined into one, what was needed was the patterns on those objects, and the book at Xu Ai's home did not have the patterns on the key parts, does that mean that if you want to combine the jewelry into one, you need to find those objects, and none of them can be missing?

But these objects belong to the Hua family. She didn't even know where the Hua family was. How did she find other people's things?

"Have your grandfather told you how the Hua family has protected the Dragon Kingdom for thousands of years? What do I mean are they doing?" Xiang Nuan asked.

Xu Ai shook her head, "I didn't say it, but I really asked. My grandfather said that no one in the Hua family had seen it, and there was no major fluctuation in the history of the Dragon Kingdom. It was just three times invaded by foreign enemies. When the Dragon Kingdom troops were defeated, a large number of enemies were killed inexplicably. Then the country would be in chaos and naturally they would withdraw their troops. Although no one had any evidence that the Hua family took action, it was a coincidence, not two or three times. Therefore, the six major families agreed that at those three critical moments, it was the Hua family who took action to save the Long Kingdom."

Xiang Nuan opened her eyes wide in surprise, "So magical? Could it be that the Hua family is a god?"

Xu Ai said, "It's indeed a bit mysterious. Even now, with such advanced technology, that family wants to save Long Kingdom, even if they have the strength, they cannot be silent. And those three times have no traces, even those foreign enemies have not found anything afterwards. It is precisely because no one can find clues that the matter becomes more mysterious. This is also the reason why Long Kingdom believes that the Hua family takes action."

Xiang Nuan nodded in agreement, "That's true, even You Zhan and Youlong can't do it."

"So, the existence of the Hua family itself is very magical, which makes me feel very fantastic." Xu Ai came from his heart, and he felt that he could find another world by finding the Hua family.

Xiang Nuan sighed and said seriously, "I think it is necessary to look at the history of the Dragon Kingdom again, and maybe I will find something."

Xu Ai smiled and shook her head, "It's unlikely, but you can try it. There may be some flaws in the most unexpected place."

The two looked at each other and smiled, and they thought of going together.

"Go to B." The two of them said in unison again. After speaking, they couldn't help laughing out loud, and the stage had a tacit understanding.

B Castle is the original Kyoto of the Dragon Kingdom, with the longest history of the Dragon Kingdom. The museum of B University can be regarded as a microcosm of the history of the Dragon Kingdom. Students studying history have always dreamed of entering the History Department of B University. Because after studying at B University, they can become history experts in the Dragon Kingdom.

"You have to find a reason." Xiang Nuan's dark eyes rolled.

Xu Ai smiled in her eyebrows, "This is not difficult. Zibin graduated from the History Department of University of B. His current job is also related to history. It should be easy to ask him to come forward and check something at the History Museum of University of B.."

Xiang Nuan's eyes lit up, and then she felt worried again. She graduated from B University, so she naturally knew how large the collection of books in B University History Museum was. She had a reason to go there, and she could not find it in a day or two. Moreover, this was a meticulous job and it was impossible to just go there.

"Do you know how big the B-Grand History Museum is? Do you have many collections of books in it?" Xiang Nuan blinked helplessly.

Xu Ai smiled, "Isn't there Zibin, a top student in the history department of B University? The collection of books in the history museum of B University is probably in his mind. With him, we will save a lot of trouble."

"Okay, you can arrange it. We will go with you then, but we will have to clean up before we can go." Xiang Nuan immediately became energetic.

Xu Ai Chunlai didn't see Xiang Nuan so emotional, which shows that she was very relaxed in front of him.

"Okay, I'll make arrangements now. We're going back to City B. It's only two hours before Nuannuan and Mr. Xiang made an appointment with him." Xu Ai looked at her pamperedly.

Xiang Nuan shrugged indifferently, "It's okay, he will have to wait for how long he will wait, and he won't wait tonight in vain."

Despite this, Xiang Nuan still put all the jewelry and keys on her backpack and left the villa with Xu Ai.

After leaving the door, Xiang Nuan said to Xu Ai, "Go to your house and have a look."

"good."

Xiang Nuan used to treating the next door as Xu Ai's home, but Xu Ai didn't correct it. In his heart, he really felt like home after living here for five years. Every day he opened his eyes and looked forward to it. Every day, he was very relaxed. As long as he saw the small figure, he walked from the lawn, walked past his window, and knocked on his door, the happy time of the day began.

Over the past ten years, he has been looking forward to it many times and saw her knocking on his door again. This wish has been upgraded today and has been walked in side by side with him.

The two walked side by side on the lawn. Ten years have passed, and the rest of the houses here have built walls or circled them with iron fences. Only the two families are still the same as when the villa was built.

The last time Xiang Nuan came back and made people restore the lawn to its original state, it now looks no different from when they lived here ten years ago. It was just that things had changed, and there was no longer the kind smiles and kind advice from Xiang Nuan's parents.

So the mood of the two has changed a lot, and Xiang Nuan has more and deeper feelings.

Yin Yuanbai walked around the villa for several times and fell asleep on the sofa. When the door rang, he woke up suddenly and stood up from the sofa in an instant.

The speed made Xiang Nuan squint. It seemed that Yin Yuanbai's ability was not just as simple as Xu Ai's follower, but also how could Xu Ai's person be weak?

Xiang Nuan's eyes fell on the grand piano in front of the window in the living room and said in surprise, "The piano is still there?"

"Well, I thought that one day I might be able to meet Nuannuan again, and then I will play the songs I liked when I was a child." Xu Ai's eyes also fell on the piano.

Xiang Nuan thought that there was also a piano in Xu Ai's villa in B City. That day, she played her favorite song when she was a child. Naturally, she remembered that Xu Ai said that he had practiced many songs at that time just to make him choose one he liked.
