In the evening, Clara's room.

She held the key, inserted it into the marble lock left by her mother, twisted it gently and opened it.

"You opened it now. I thought you opened it as soon as you were free." Gray looked at her movements and smiled.

Clara stared nervously at the marble lock and replied again: "there were too many things yesterday. I was too tired. I fell asleep as soon as I lay in bed. I forgot. I remembered when I saw the new machine today."

Clara put away the key, gently opened the marble lock, frowned at once, and the smile on her face disappeared.

"It's impossible, it shouldn't be!" She whispered to herself.

"What's the matter?" Gray leaned over and saw what was in the marble lock. A burst of music came out of the marble lock.

There is nothing in the marble lock, just the marble lock itself.

"It's a music box. How can it be? It's just a music box?" Clara couldn't believe it.

Mother left her a music box, and she took great pains to get the key to open it. It turned out to be just a music box, which was disappointing.

She doesn't expect anything valuable, but at least it should be something of commemorative significance. How can it be an ordinary music box?

Gray saw her disappointment, pointed to the music box and said, "maybe the music itself has any special meaning. Listen carefully!"

Clara nodded gently, put the music box on the table, put her arm on her cheek and stared at it faintly.

The soft music flows out slowly. Clara feels as if she is in the sea of flowers in the morning. There are clear birds singing in her ears. Everything is relaxed and comfortable.

Gray also listened attentively. This is something that a person who created a world can compare with Aslan's characters. Maybe there is something mysterious, but it is difficult to be found.

After listening to a song, he played it again and again, but he still didn't hear anything. It seemed to be just simple music.

Just as he comforted Clara, he didn't believe it was just a simple music, without any special information or magic.

Clara blinked at him with big beautiful eyes. She didn't find anything else, so they agreed to listen again.

The elf hit hatchet, flew over gray's head and fell asleep on his stomach.

Clara listened to the music for a while and didn't hear anything. Instead, she remembered the previous things and asked, "gray, did the Sugar Plum Fairy just want to rob my key?"

"You see!" Gray nodded gently. It seems that Clara is not stupid and sweet. She still has a brain.

Otherwise, she should be concerned about Sugar Plum Fairy and ask why gray just caught her.

"There are many contradictions in Sugar Plum Fairy's words. She told us that the citizens of Queen Jiang's mother betrayed her, but she said that queen Jiang's army is very strong and the Three Kingdoms can't beat her together."

Gray smiled and analyzed, "how is this possible? No matter how bad the people of the three kingdoms are, they can't even stop a ginger queen who has lost her subjects! "

He was talking about blocking, not winning. After all, if the people of the three kingdoms were really waste, they might not be able to fight.

"The troops here are made of toys by your mother. The gap in combat effectiveness can't be too big."

"Even if queen Jiang's mouse soldiers are stronger than the army she had at the beginning, they can't even have the power to defend!"

"Then, it was her desire for the key. She wanted to get the key very much."

"This shows that she needs that army very much, and it is the army in her hands. She absolutely listens to her orders, not in your hands or in the hands of any other Regent."

"So what she wants is not an army, but the strength of the four kingdoms."

Clara nodded thoughtfully, "so, the queen ginger is right. Is it really sugar plum fairy who framed her?"

"Not necessarily. After all, we've only been here for a few days. My guess about the behavior of Sugar Plum Fairy is entirely in my guess. Maybe I'm influenced by Queen ginger and think she's a bad person." Gray shook his head and didn't say too much.

Although according to the ELF's judgment, the Sugar Plum Fairy should be as the queen ginger said.

But this was indeed what he observed after preconceived according to the ELF's judgment, so he felt that he should be fair and give Sugar Plum Fairy a chance to show.

"So whether it's her or not, we just have to wait for a while!"

"Wait?" Clara doesn't understand that even if Sugar Plum Fairy is a conspirator, she can't explode.

"If it's really her, she will certainly find a way to get the key from you. Maybe it's rhetoric to ask you to give it to her. If you're tough, it's possible to rob or steal it directly."

Gray said confidently, "as long as she does, she's right."

Clara suddenly and carefully said, "what if she really gets it, then she can make a lot of troops?"

Obviously, if the little girl thinks the enemy is really a conspirator, she can't carry it. She may take it away by some way.

"It doesn't matter. I'll protect you!" Gray said without hesitation.

"But now that we have thought of this, we'd better be on guard lest she really take it away!"

"How?" Clara looked at him expectantly.

Gray touched his chin and thought. He took out a piece of metal, clenched his hands, rubbed it in his hands, and opened his palm again. The metal block had disappeared and a key appeared in his hand.

Clara, as like as two peas in surprise, said, "I'm just the same as mine."

"It just looks the same, but it's still a little different!" Gray smiled.

Clara took out her original key. After comparison, she found that the two were different in details, but they looked the same at first glance.

But with this key, there must be no way to open the new machine.

"You are so powerful that you can make such realistic things at a glance." Clara as like as two peas, "now you can see if you can make the same key."

"I can copy it perfectly at a glance!" Gray smiled triumphantly.

"But I won't do that. That's what your mother left you. It should only belong to you. Neither I nor Sugar Plum Fairy can take it away!"

At last, his eyes became serious.

"Thank you, gray!" Clara was moved.

"You're welcome, I'm your knight!"

Clara smiled and the atmosphere in the room became happy again.
