I can't go back to the blood oath tonight, so I have to spend the night in the old mansion with Lilith.

In the old mansion of Nuoda, Hangichiro naturally lives in the room of Lord Ernest, and with curiosity to know about the owner of this body, Hangichiro casually looks at the books in the room, but most of these books are the history of the Gaeland Empire, or some teaching books on governing the country, or some science study records of monsters.

'You'll always find some clues left by the original owner, right?' The original owner seems to be a person who is very interested in governing the country, but I don't care about the family and status, and my attitude towards life is to be free and happy. ’

Hanichiro found a random place to sit cross-legged and looked through some books, although he could increase some knowledge of the customs and history of the Tewath continent, but it was not important.

Before I knew it, it was late at night, looking at the long and boring history books of the Teyvat continent, Koichiro yawned a few times, "I'm not from this world, so it's useless to know so much family history...... It's better to wash and sleep. ’

was about to get up and put these history books back in place, but when he stood up, his leg was numb, he fell sideways, and a stack of books fell in his hand.

After a while, the numbness in his legs had subsided, and he went to pick up the book he had just dropped.

"Huh? What about the one Lilith gave? ”

I found that I couldn't find it, so there's no reason.

Koichiro looked at the trajectory of the fall, "Fell under the bed?" ’

Looking under the bed, Koichiro found Lilith's book, and by the way, he found a secret compartment under the bed.

"Huh? Where do the people of Teyvat still hide their money? He smiled, and while picking up the book, there was something else.

'Is this compartment still locked?' Hanichiro couldn't pull it away after a lot of effort.

With the theory that I could pry an earth by giving me a fulcrum, Koichiro found a hammer and hammer from elsewhere, intending to pry the hidden grid open and smash the floor if it didn't work.

The results are rigorous......

"Lilith said that the Eye of Horus can be attached to ordinary items to get a greater ability bonus, so try this."

Koichiro placed the Eye of Horus on top of the hammer, and the Eye of Horus seemed to sense a weapon, and after detaching from his hand, it could levitate above it, "With the Vision of God as the source, the light is fused." ”

Then the Eye of Horus emitted a faint glow of streamers, as if absorbed by the hammer, and disappeared in a moment, while the hammer in his hand became lighter, and smashed down with the usual force, and the floor under the bed suddenly cracked.

"Ah, ah, I didn't know it would be like this, but I really caused trouble for the Warrens family......" Koichiro was deeply embarrassed with the hammer and apologized to the air.

Then, when I opened the dark compartment, I saw that there was a hexagonal gem inside, emitting a faint green light, and nothing else.

Koichiro picked up the faint green gem and looked at it, "What is this?" ’

Traveling to the world of Tevat, there are already too many strange items and magic, and now Koichiro is not too surprised by this, thinking to himself, let's put it away first, and ask Lilith tomorrow.

"Let's rest early today, I'm a little tired", glancing out the window, there was only an incomplete moon in the dark night sky, and Koichiro retracted his gaze, took off his coat, and lay down.

I couldn't open my eyelids, but my mind was still beating actively, so I simply closed my eyes and rested.

Now that he has decided to find a way to complete the various assassination missions of the Blood Oath, overthrow the dark rule of the Empress, and find out the culprit who brought him to this other world, and finally return to Tokyo......

'I feel like I'm in a reasoning game again!' 'Naturally, Koichiro had to find ways to strengthen himself in the shortest possible time.

"Damn, this is not the real world, there is no way to add krypton gold to attribute points, I originally thought that I had crossed over to the Teyvat continent and obtained a prophecy plug-in to know the future situation, although I couldn't directly enhance my strength, but at least I could survive. Now I suddenly found out that this is actually a, a save point observation perspective ....... ”

Thinking of this, Koichiro slammed his fist on the bed and sighed heavily, as if he was thinking and as if he was indignant.

Unconsciously, his breathing gradually calmed down, and the man fell into a deep sleep.

--

In a dream, the green light is shining beside him, but this is not a hint from the old king next door, but a mysterious source force is working......

The dark green gem that reflected the moonlight could absorb the moonlight, and the moonlight reflected with it, and the source power contained in the dark green gem was urging the mysterious magic circle, and the magic circle was faintly showing signs of destruction.

In the room, an inexplicable source force began to permeate, and the two people in the silent castle were sleeping peacefully, and no one noticed.

The index of memories of Lisa, the god of thunder, gradually collapsed under the intersection of the faint green light and the Yingying streamer emitted by the green gem and the eye of Horus at the same time, and the index of memory arranged by Lisa in Hanichiro's mind "clicked-" and was melted by the spiral convergence of light, and then lost its effectiveness.

The Eye of Horus guides the dream.

In the midst of the black clouds, in the midst of the torrential rain, Koichiro grabbed the sharp horns and hurried through the rain, and the torrential rain dripped from the bridge of his nose along the long bangs. Something strange was chasing after him, as if he was a man in a brown-black robe, an empty robe, a creature without a face or feet, with only two hands, one holding a wand that resembled a cane.

'What the hell did this come about......

What a dream that challenged the limits, and I dreamed that I was being chased by something, and it happened that Ashley's bone dragon saved me?

After waking up, Koichiro felt very tired, as if he had experienced a thrilling escape in a dream, but it was only a real reality and he had avoided it all night.

"Did you also have a dragon in your dream......?"

Familiar memories emerged, and Hanichiro's missing memories resurfaced, "I suddenly remembered this, although it was a little strange......"

I have indeed been to the old mansion of the Warrens family, and the last time I came to the old mansion of Warrens with me, there was also an abyss black dragon that hatched and reappeared from the Fallen Shadow Underworld.

However, last time, I met the original god here, Lisa, who was in charge of the source power of thunder, but because she was not a messenger of the gods at that time, she did not have the right to meet the face of the original god, so her memory was temporarily sealed by Lisa.

Although the seal at that time was related to Lisa, the primordial god, since it could be sealed in the world where humans lived, then everything was mutually reinforcing, and there must be a way to break the seal.

A flash of inspiration.

"Is it because of this gem?" Koichiro grabbed the gem next to the bed, it was dark green now, there was no green light in the daytime, and the whole body was cold.

Comparing it to the Teyvat full-category magic stone science picture book that I looked through last night, I turned hundreds of pages and found the same drawing from the dragonstone summon, and even its usage.

I saw Teyvat's full-category magic stone science picture book impressively written:

[Name]: The Heart of the Green Dragon

[Condition]: High-grade magic stone, the whole body is dark green, reflecting the glow of the moon shadow under the moonlight

[Holder]: Fallen Angel Motesma

[Use]: Summons the Ancient Fallen Shadow Underworld Black Dragon

[Related]: ......

The following and so on......

After detailed identification and reading, Hanichiro looked at the gem in his hand with some reluctance, "You can summon a black dragon, is the holder Mortisma Love?" Try it, right? Memory loss is really troublesome, but if you still have the memory of the original various ways to die, it's also an unacceptable thing, and I don't know if I have the courage to live again. ”

Pregnant!

Koichiro felt that the most powerful opponent he had encountered so far, except for the empress Sirides who had just come to the other world, was probably the black dragon, it seemed that it was the ancient black dragon from the Fallen Shadow Underworld, and Nexus was already GG so it didn't count.

"If I can subdue it, then my success rate of completing the various assassination missions of the Blood Oath will be greatly improved. Naturally, there is a chance to go home as soon as possible...... I'm afraid that the time flow of the two worlds is inconsistent, and when I go back, I will already be different. ”

After making a decision, Koichiro quickly began to act.

--

Morning.

Koichiro came and knocked on Lilith's door.

"Huh? Morning, Your Excellency......" Lilith opened the door with a blanket, and in the past she used to have delicate hair in a delicate bun, but today she saw a slightly messy dark gray long hair, which looked more down-to-earth.

In Lilith's surprised gaze, Koichiro explained the purpose, as well as the missing part of the memory.

Lilith hesitated and said, "Huh? Are you serious? The primordial god can only be seen by the messenger of the corresponding element, right? ”

"But I did meet the primordial god of the thunder attribute, and she is also the administrator of the Divine Realm Library."

"Your Excellency means the Divine Realm Library? I seem to have some understanding, but I have never seen it, and the first two times Your Excellency did not have this part of the process. ”

Koichiro handed it to Lilith

So the two talked about the solution for a long time, and finally when the blazing sun was in the sky at noon the next day, the two were full of ambition, obviously having a way to deal with it.

The underground library of the old Warrens family's home.

"Your Excellency said here?" Lilith asked.

Koichiro nodded, but there were a few more people on his side, Ashley, Brude, and Itina.

"Lord Lilith, you're the only one who can summon us out to work around, oh my ......nap," said Ashley, who was swearing to do nothing and preparing to take a nap with sleepy eyes.

"Oh, slacker!" Lilith looked displeased, and even tried to trip him and make him sober up in the street.

The pink tsundere double ponytail frowned, listening to a lot of news with a head and no tail, and vaguely guessed that he had come to the old mansion of the Warrens family to summon the ceremony.

"Lord Ernest, is this it? This is where the evil black dragon was sealed? It doesn't look like a place where the gods have ever set foot. ”

Hangichiro nodded with a determined face, "That's it, Lilith, let's hurry up and arrange the ceremony of breaking the seal together." ”
