This elf is so insane

Sword Spirit and Gu Yu reached a reconciliation. He can do whatever he wants from the side, but he cannot disturb Gu Yu, cannot actively appear in her sight, and cannot leave her more than 100 meters away.

Although the girl who woke him up from his slumber was mysterious and terrifying, Sword Spirit was more concerned about how she would deal with him.

According to past experience, discovering that your weapon has a spirit should be a joyful thing. You will be happy for at least a few days, and you may even hold a banquet to entertain guests to celebrate your weapon spirit.

The mysterious girl in front of him, who was neither happy nor sad, as if she did not belong to this world, was able to ignore him. She seemed to have no wishes and no desires. It was really strange.

But the girl is an elf, and elves have been extinct in the monastic world for a long time. Perhaps the girl is the only elf in the monastic world now, and the mission she carries may be more important than obtaining the sword spirit.

With this thought in mind, Sword Spirit accepted Gu Yu's request.

……

Guyu has read everything in the bookshelf, and there is still no other creature setting foot here, so the worst news appears: the secret realm has been closed.

She is very familiar with this secret land. Every plant and tree here is her eyes. Although she cannot talk to the plants here, she can still know if there are any creatures visiting here with the help of their feelings.

But why is the secret realm closed?Guyu couldn't figure it out for the moment.

Hearing Guyu sighing, Sword Spirit cautiously approached and asked, "Master, what's wrong?"

Guyu held her forehead: "I am not your master, your master is someone else."

Sword Spirit shook his head: "My last master has passed away. I don't know what happened when I was sleeping, but since you woke me up, you are my master."

"You are just a weapon lent to me by my friend for self-defense. I will return the sword to him when I get out."

"However, if a weapon that has recognized its owner is forcibly held by others, it will trigger the backlash of the contract, and this backlash will come to the holder. This is a unique contract for weapons with sword spirits."

Guyu looked at the contract formation and found that it was true that the sword had indeed been included in the contract, but it was separated from the sea.

This is troublesome. This is a relic of Qing Muchen's mother. Now he is not only trapped in this secret realm with her, but also contracted by her inexplicably. I don't know if Qing Muchen will be so angry that he will collapse when he finds out. Crying and fussing, oooooooooooooooooooo pitiful...ahem!

But there is no way out.

From the contents of the books on the bookshelf, Guyu learned some hints about the owner of the cave, and this hint could only be discovered by elves. One of the important reasons was that the fresh saliva of elves could make certain words written with special potions appear.

This message was also written using this potion. The reason was that when Gu Yu was resting in front of the case, sweat dripped on the scroll, so this message appeared in the blank space of the scroll.

Unlike other elves, Guyu's sweat has the same effect as the saliva of ordinary elves, which saves her a lot of trouble.

After pouring his own sweat on all the scrolls of the same category, Guyu gathered the information left by the owner of the cave: to enter and exit the small world, you only need to be infected with my aura and use this formation.Remember: Wuguo lineage is the lock of the secret realm.

Guyu remembered that the word Wuguo appeared in the fragment, but the following content was in other fragments, and she had no way of knowing.

So, you just need to bring something here to cast the formation and you can go out?What does the following sentence "Lock of the Secret Realm" mean?

Just as Gu Yu was thinking, she felt someone pat her from behind, but the sword spirit was right in front of her...
