In the hometown of starfall, Tianze met Li Mu for the first time in the living room. Li Mu, Lu and Tianze sat around a small table.

Due to the loss of Princess Erwin, Li Mu, who had no choice, had no choice but to return to the land of Starfall to discuss the follow-up matters with Lu and Tianze.

After all, he still doesn't know anything about the Moon World, and if he wants to save Princess Erwin, he first needs to find the entrance to the Moon World, and the person who is most familiar with the Moon World in the entire Ilbut should be none other than Tian Ze. At that time, the conversation between Tianze and Ang, Li Mu heard it clearly outside the window.

So he decisively found Tianze and Lu together, and told the two of them what happened.

"yes, something like this happened." Tian Ze frowned.

"Princess, Your Royal Highness, you will be arrested," Lu cried with a sad face, "You must be a liar." ”

"I'm sorry, it's my responsibility not to take care of Her Royal Highness the Princess, if you have any dissatisfaction, just scold me." Li Mu sighed.

"Don't lie to people, can you come back if you scold your princess?" Lu said angrily, "Waste, pervert, idiot, stupid, die." ”

"Aren't you scolding quite cool? I know, Her Royal Highness the princess's lip service should be thanks to you. Li Mu looked at Lu and said.

"You, what are you talking about, you coward! Really, I can't wait any longer than you, and in that case, I'll go to the princess myself. Lu said as she flew out the door.

"Wait, where are you going by yourself, the princess was taken away by teleportation, I guess it should be in the Moon World, do you know how to get to the Moon World?" Looking at Lu who was in a daze at the door, Li Mu turned his head, "Lord Tianze, I want to ask what this thing is." Li Mu said as he took out the sawtooth sword and put it on the table.

He instinctively felt that what even the hooded girl had to fight for was obviously a very important thing, maybe there was a clue about the world of the moon. Moreover, the name of the key that this thing is also given may be the key that opens the real door to the moon world.

"What is this?" Lou flew back at this point.

"Well, has the seal been lifted?" Tian Ze showed a look of understanding, "As you can see, this is the key used to open the door to the Moon Country, or the Moon World, five hundred years ago, my ancestors were entrusted by the Duke of Giscard to guard this sword. ”

"Sure enough, in that case, does that mean that as long as you use it, you can enter the Moon World to rescue Her Royal Highness?" Li Mu asked.

"Well, that's true, originally this key was only used to deal with the situation that the Moon Mirror that was sealed in the city was taken away, and only by using the mirror can the passage to the Moon World be opened, and when the road is opened, the key can open the real door...... "Old Man Tianze said slowly.

"I see." Li Mu nodded clearly.

"It's so troublesome." Lu had a headache on her face.

"In short, the Duke of Giscard has taken many countermeasures just to beware of those who have gone astray for the power of the Demon King." The old man Tianze concluded.

"Demon King, is it really a Demon King?" Lu exclaimed.

"Well, it seems that Domin also mentioned the power of the Golden Demon King, and it seems that what they said is true." Li Mu nodded.

"Well, the Golden Demon King Lucia, five hundred years ago, Duke Giscard and our ancestors fought the Demon King, it is said that this guy has extremely powerful magic power among the six Demon Kings......"

"Could it be that guy reborn?" Li Mu is very familiar with this plot of the rebirth of the demon king. Anyway, many of the scripts of the Demon Quest are set in this way.

"No, according to the records of the inheritance, the Demon King has been completely destroyed, but that great magic still exists in the world, according to some accounts, it is an extraordinary magic power that is enough to cause a mutation of heaven and earth."

"I see, no wonder Princess Erwin's father wants to seal this power." Li Mu nodded. As for why the demon kings were all killed, but the magic power is still in the world, Li Mu doesn't want to ask this stupid question, anyway, there are always a lot of reasons, such as this magic power will pollute people's hearts, or this magic power is unusually powerful, such as the duke was seriously injured or something at that time, and it seems that there is no point in discussing this issue now.

"Well, it seems that Zaharare has obtained the power of the Demon King, and then in order to use it, he needs to use Her Royal Highness the Princess, as for the specific form, it is unknown." The old man Tianze told his guess.

"Oh, Your Highness Princess," Lu cried as soon as her eyes turned red when she heard this.

"I see, so what we have to do now is to go to the Moon World to retrieve Her Royal Highness, so where is the place to use this key? Is it on this mountain? Li Mu asked.

"No, it's not here, it's in the ruins of a dark crystal near the city of Montbria." The old man Tianze said.

"The remains of a black crystal build?" Li Mu showed a questioning look.

"Well, that's supposed to be Crystal Valley, just near the city of Montbria, you've seen it many times." Lu thought for a moment and said.

"According to what you said, I remember that there is indeed a door-like thing in the north of Crystal Valley, I originally thought it was just an ordinary ruin, but I didn't expect it to be a gate to the Moon World." Li Mu sighed.

"Now there is a problem, even if you get the key, you can't open the door." The old man Tianze said suddenly.

"Why is that?" Li Mu asked.

"First of all, you need a strong magic power to awaken the gate, and I'm afraid this requires a strength that matches the vampire True Ancestor." The old man Tianze said.

"The same magic as Her Royal Highness the Princess? This is simply ridiculous. Lu looked incredulous.

"Is it the same magic as Her Royal Highness?" Li Mu suddenly had a flash of inspiration and thought of something, "Although, we can't find anyone with the same magic power as Her Royal Highness the Princess, but we can find a few people who are slightly weaker than Her Royal Highness the Princess, such as Pipilo, such as Laella, and even Fiona should also know some magic, if you gather the magic power of these people, can you also wake up the door." ”

"In this case, there should be no problem," said the old man Tianze, "The guardian's responsibility is to guard the key, and inform the inheritor of the above words, it seems that I have also completed my final mission." I'll leave the rest to you. The old man Tianze said and bowed to Li Mu.

"Well, that's the case for us," Li Mu nodded, and then he said to Lu, "Let's go back to Arudia Town first, and gather everyone first." ”

"yes, okay." Lu happily agreed.
