Chapter 1833

"Deal with that fortune teller?" The devil immediately shook his head:

"No, no, I just can't believe you actually kept your promise and let me leave. In my opinion, you are even more... cough cough, I've already intervened in enough trouble here. If you want to deal with him, you must be careful."

That was probably the most easy-going devil Xia De had ever seen. However, seeing the other party shrink into the bottle and really intend to leave, Xia De called it back:

"Wait a moment!"

The devil, whose upper body had just shrunk into the bottle, floated out again, crossed its arms in front of its chest again, and said in an "as expected" tone:

"You really still want to use me? Have you prepared yourself to make a deal with a devil?"

"I just want to ask you a question. To be precise, ask you about other devils."

The doctor sat on the side and listened. Although he had a lot of information about devils, he didn't know all of them after all; he only knew those that were somewhat famous.

A few seconds later, at the other end of the city under the night, at the entrance of a famous alley in the slums, with a soft "bang," the magic bottle appeared in the moonlight. It quickly drilled into the shadows and flew toward the high altitude under the cover of the shadows. Finally, it stopped at the edge of the roof, and the blue face formed by the smoke in the bottle looked seriously at the middle-aged man walking out of the dilapidated tavern with lights on in the slums.

"Mia, jump up! 140-degree mid-air rotation, then follow with a backflip!"

"It actually has something to do with this investigation mission. After all, the degree of breach of promise between Mrs. Miles and that young knight is truly astonishing... Although this ability is not for combat, establishing a vow like this is very convenient for daily investigations and similar activities."

"However, since I plan to leave here anyway, I might as well go find their whereabouts. The world is becoming more and more dangerous. Even if I am a relic and a devil, so what? I hope we won't meet again in the future. I wish you two good luck."

Of course, the vow is also binding on Xia De himself, and Xia De himself must also bear the backlash after he violates the vow. But relative to the other party, the impact of the spell on Xia De himself will become very slight, and he can even pay spirit to offset it. The effect of this spell is mainly aimed at those who make promises and vows to Xia De, ensuring that those promises will definitely be fulfilled:

The evidence lies not only in the specific ability displayed by the spell, but also in the fact that once both parties establish a "Vow Binding," a faint, pale golden scale mark will appear on the forehead of the other party besides Xia De. This mark can only be seen by Xia De, the caster himself, and some extremely special existences.

He issued an order to the cat, but the cat just squatted there looking at him, then blinked its large amber eyes. This instead made Xia De feel that his intelligence had been disrespected.

"Eh?"

"What was the full text of the wish made when that devil-man summoned the devil for the second time?"

He wanted to reach out to catch the cat, but then thought of the premise of using the spell "Vow Binding," which is that both parties can understand the content of the vow. And although Little Mia is smart enough, there should still be a distance before she can understand all of Xia De's language.

The leaf was taken away by him, and Xia De received the spell reward for this time-adventure.

"First is this one."

"It was probably a description like 'a devil that can defeat a devil,' and the other party didn't explain this point very clearly. As for that devil-man... he definitely can't be found now."

Of course, the value of the two brand-new 【Ye Zi of Eternal Youth】 is not just in the leaves themselves; the power and knowledge recorded on them are the most precious:

"The range is too wide, and there are too many peers that can meet the conditions you mentioned."

Regarding this "Vow Binding," although a power with similar uses could be found in the Third Era, the prototype could not be found in this era either. However, the power of this spell is quite easy to understand.

Xia De described the butler and maid of Stone Osenfurt as carefully as possible. The two devils gave him a hint about the incorrect animal option in the last riddle of the "Stone Mirror Devil—Gothe." Looking at it this way, although they displayed weak power, they could see through the Stone Mirror Devil's tricks, which in itself is very strange.

During the period when the vow is not completed, the object that has established a binding with Xia De cannot violate the vow they made in any way. When making a promise, both parties can agree on the price of following the vow. Once the vow is violated, it will be punished according to the degree of breach.

But this is hope after all. You must know that Miss Danister only spent a large amount of funds to open the ritual to enter the library to get the "highest authority" just for the information of the one-time ritual "Calling the Silver Moon Library," from the time Xia De met her until the eve of the Chosen One event.

"The Father of the Infinite Tree really can give any power."

He faced the window where the rain was falling, picked a leaf at random and placed it in front of his left eye socket, while Little Mia stood on the windowsill and watched this scene with great interest. The cat saw golden light traces flowing along the green leaf veins, and finally all the light entered Xia De's eyes.

"Your behavior is quite stupid, and the two brand-new devils you summoned don't seem to have particularly powerful skills. They transformed into a maid and a butler to take care of the manor for the devil-man. And when that devil faced an opponent, they provided effective information to help the demon hunter who broke into the manor, in exchange for them getting rid of that powerful binding contract."

"I'll experiment again when I find an opportunity in the future. But this is not a spell that can be cast casually; I can't rely on this to make infinite vows and infinite enhancements. It's necessary to use it again. But since the first leaf is a spell, the second one must be..."

"Spell—Vow Binding."

Before completing this investigation mission, he already had a leaf in his hand, and Luweiya, Dorothy, Lei Qianya, and Yiluna also had one. Therefore, even facing the upcoming decisive battle at Green Lake, his leaf reserve was more than enough.

Xia De shook his head:

He sighed in his heart again, and then wanted to try this brand-new spell. It was just that he couldn't cast it by himself, but he couldn't find anyone else to make a contract with now, so he aimed at Mia, who was watching him on the windowsill. Little Mia must belong to a wise creature.

It shrank back into the bottle, so its voice was a bit muffled:

Besides establishing a vow binding between the two parties, this spell has another powerful characteristic: every time a vow is established and completely fulfilled, it will feed back an enhancement effect of physical and mental strength to Xia De. Although the effect is not particularly good for Xia De, whose physical and mental strength already exceeds that of an ordinary ring warlock, he also quite likes this kind of enhancement without a price.

The blue genie whose main body is the wish devil—Zatanna thought for a while:

"Not clear."

That was actually the story of Stone Osenfurt.

If Xia De didn't guess wrong, Yiluna belongs to an extremely special existence.

"My clansman? You ask."

Xia De looked at the remaining leaves. Regarding this leaf, Xia De actually worried that it would be "confiscated" because of Xia De's special requirements, just like the leaf with the 【White Night】 spirit rune reward during the "Eternal Night City" time. Therefore, he had been careful and cautious during this adventure in the White Mist Camp.

Devil scholar Mr. Shawn Asmon seemed to feel something and suddenly looked up at the roof of the street under the moon, but there was nothing there.

(Little Mia is running...)

Most of the spells and wonders given by the Tree Father, Xia De could not find corresponding powers in the Third Era today. And the knowledgeable witches and 13th-ring warlocks like Miss Danister believe that the power he uses is very similar to the ancient god divine arts of the ancient era.

"A mortal who made a contract with a devil became a devil-man who uses devil power. But one day he regretted his decision, so he intended to summon a devil again to kill the weak devil that turned him into a devil-man."

Of course, he definitely wouldn't try it casually. What he really cares about is that this spell doesn't look like the power of "time" at all, but rather like the power of "balance."

He had asked the doctor later, but the doctor didn't know their origin either. Xia De didn't delve into it later, after all, the other party helped him. He remembered this matter just now, so he asked.

His head was very bald, with only fuzzy stubble. His skin was dark, his double eyelids were extremely obvious, and he was wrapped in an unusual brown old-fashioned robe that people in desert areas often wear, holding a notebook with slightly curled edges in his hand.

"I reach out my hand and hold hands with another wise life that has organs like arms/claws/tentacles/antennae, and then both parties repeat a vow three times together, and a 'Vow Binding' can be established between the two parties... It's really simple and easy to understand."

The cork automatically plugged back in, and with a soft "bang," it completely disappeared in the colorful smoke.

"If I look for it myself, I don't know when I will find it. This time is an opportunity."

Xia De was quite satisfied with this spell, and then had a sudden whim: what would happen if he shook hands with himself?

After leaving the doctor's room, Xia De still hadn't waited for the two witches who went to the meeting to return. So he returned to his room first, played with the white scales and the bronze bell engraved with golden characters, then took a deep breath and took out two 【Ye Zi of Eternal Youth】.

Thinking in his heart, he had already placed the leaf in front of his eyes again.

The blue genie floated below the coffee table.

And now, when this leaf was really lying in his hand, Xia De really couldn't describe his uneasy mood at this moment. He knew very well that he probably couldn't enter the 【Silver Moon Library】 again just by the knowledge on the leaf, and then have a chance to see Him in his sleep through the remains of the original moon in the Silver Moon Library.
