In the Demon Realm, under the eternally gray sky, a solemn purple-gold palace stands, and there is a dark purple sun in the sky, but it only has the brightness of the starry sky of the human world. The purple-gold palace is the palace of the demon clan, in front of it is a huge square, there is only one statue in the center, and on the west side of the square is a purple three-story purple bamboo building, which is a library that can only be entered with the permission of the royal family, and is known as the forbidden place of the royal family.

Every day, a little palace maid cooks food and enters the library to deliver food to His Royal Highness the Prince, who lives in the library. Judging from the appearance of this palace maid, there is not much difference between the demon race and the human race, the skin of the demon race is unusually fair, the pupils are completely ink-colored, and there is no impurity, maybe because there is no light, the pupils have evolved like this, and the demons can see in this world without light by relying on this pupil.

Empty String - The Demon Prince, but his actions are a madman with a strong desire for forbidden books, and he uses his privilege to study all kinds of forbidden arts in this library full of forbidden books. Three months ago, Kong Xian made a bet with the Demon Emperor, as long as he found and cracked the door that opened the door connecting the Demon World and the Human World, the Demon Emperor would agree to Kong Xian's one condition.

Kong Xian is a prince who doesn't want to be an emperor, and the Demon Emperor thinks that Kong Xian wants to use this great merit to remove the identity of the prince. So the Demon Emperor agreed.

Kong Xian found the book that recorded the way to get out three months ago, and it was only time to crack and practice. And today, he finally broke through a hurdle, and he decided to go out and have a look!

"Empty strings, it's time for lunch. The palace maid Yue pushed open the door of the empty string, and the empty string answered the hello, cleared the things on the desk, and put the food on the table.

Although the moon is a palace maid, she is also the only maid of the empty string, and she is a childhood sweetheart regardless of her identity, and the empty string does not let her call him His Royal Highness, and tells her to cook for herself herself, and to accompany her to eat and chat.

"I'm going to go shopping on the street with you today, and I'll help you buy some things to celebrate my next success!" Empty String decided with a smile as he ate the dish that Yuegang had put in his bowl with chopsticks.

Yue hurriedly shook her head and refused: "If you succeed, buy something for yourself, what do you buy for me?"

"I'll be happy to buy things for you, what's the fun of buying things for someone who wants everything?"

Yue's face instantly turned slightly red, extremely cute: "I like it...... Buy me a kite, I want a zither of my own. "So I can play it to you alone.

"Okay. Cooking skills haven't grown, it's still a taste. ”

"You can only put spicy dishes for sweet dishes?"

"You can try, hahaha. ”

......

On the street, Kong Xian noticed that Yue saw a hairpin and left a look, so he bought it directly, and then ran to the store to choose a high-quality kite. It is not difficult to see that Kongxian likes the moon, a prince is so good to a palace maid, and there is no cover-up. In everyone's eyes, this palace maid is already the first favorite concubine.

"I'll help you get it back. "It's a little hard to see the moon holding the zither, and the moon hugs it tightly and doesn't give it," I hugged it myself. "As a prince, don't you have a little self-knowledge, and rob the palace maid......

Kong Xian then took the moon to the back mountain of the palace, walked to a sundial and stopped, he often ran to the back mountain to practice martial arts, although he didn't know what this thing was, but this was the mystery of the puzzle he solved. When the sun appears, put the jade into the depression and the door will open.

The empty string groped on the sundial, "There really is a depression! It's a jade!" The last puzzle was what kind of jade it was, and he tried several times with different pieces of jade, but no door appeared.

Yue quietly stood aside with the zither in her arms, looked at the empty string and shook her head, and asked, "What are you doing?"

"Surprise!" Kongxian hugged the zither in her hand and took the moon back to her room, studying what kind of jade the last jade was in the sound of the moon's zither.

The sound of the strings is crisp, the moon's eyes focus on the empty strings of the book seriously, this picture does not stop until the moon is finally tired of playing, the sweetness in the moon's heart has reached the peak, and the small wish of playing the piano for him has come true, it's good!

The moon quietly sat next to the empty string, and looked at the book of the empty string, the book drew a round cake-shaped jade, the moon is a book read with the empty string, and the book wrote, this is one of the ten major artifacts, Qixuan jade, a space spirit weapon, which can transmit the user anywhere, and has the coordinates of the whole world.

"Empty strings, does that jade refer to this?"

"It shouldn't be, the shape is different, and besides, there is no need for a formation with this jade. "It's almost dinner time, let's go cook." ”

"Oooh. Yue stuck out her tongue, this is the privilege of the empty string palace maid, the only palace maid.

......

In the room of the Empress of the Demon Palace, the beautiful Empress was looking in the mirror, and suddenly the beautiful face in the mirror changed, like a ghost.

"If you're going to find him today, you don't have to bother me anymore. The Empress was accustomed to the appearance of this ghost, and spoke in the same tone as her friend's voice, a friend who liked to be a light bulb.

"Hehe, I hope you control yourself, otherwise your hand suddenly pulls out a knife and stabs him, and you will die!"

"You don't have the strength yet. The Empress pursed her lips and left the mirror.

The Demon Emperor is a dedicated person, but the woman he loves is not the Empress, no matter how much the Empress pleases him, it will be useless, but the Empress also loves him deeply, and even gives everything for him. And this ghost is one of the prices of becoming an empress.

The Demon Emperor was training the legion outside, and next to him stood a young man who was similar to the Demon Emperor - the empty evil, the son born to the empress and the younger brother of the empty string.

Since Kong Xian doesn't want to be the Demon Emperor, then the power to take charge of the army has to be given to his only younger brother, if Kong Xian really studies the method of going out, it is the moment when their demon clan returns to the human world, training becomes very important. The entire Demon Realm was busy.

At this time, the empress rushed over, "This is what I cooked myself, Your Majesty tasted it." ”

The empress went to cook herself, but the emperor didn't appreciate it, "It's not dinner time yet, but I'll eat it after I finish training." ”

"Yes, Your Majesty. The Empress didn't leave, she stood next to the Demon Emperor.

"Your Majesty, why are you starting to recruit troops now?, have you found that there is a new boundary on the border of the Demon Realm?" the Empress suddenly spoke.

"We've found a way to return to the human realm, and we can finally reclaim the continent that belongs to us!" the Demon Emperor began to get a little excited when he mentioned this.

"Whose credit is this, it should be rewarded, why haven't I heard of anyone so powerful, who has solved this problem that has plagued our demons for hundreds of years, and there is no movement at all?" The empress was shocked, and the ghost was also shocked.

It seems that the action must be accelerated, otherwise they will all go out, this is not good, the Demon Emperor must die!

"It's Brother Huang. The Empty Evil questioned his mother's tone that was different from usual, but he was a real facial paralysis and did not reveal anything, but answered his mother's question.
