The town is very quiet, everything is lazy, rows of Western-style houses, blue-gray stone paved clean and tidy streets, and the drainage ditches on both sides are still flowing with clear water at this time.

The smoke of the cooking could be heard, the crackling sound of the oil being heated, the aroma of the food and the small chatter.

The streets were sparsely populated with pedestrians, and shops were tidying up their stalls.

Along the way, many people greeted the housekeeper after seeing him, and the housekeeper responded kindly.

Entered the manor, and stood in the hall, where a line of servants stood respectfully on either side of the y.

"Go and prepare the meal, Childe should be hungry after walking so far. The butler commanded, "By the way, what about the Duke?"

"The Duke is in the study, and he ordered to go to the study to find him when the young master returns. One of the maidservants said.

"That's fine. The housekeeper said, then turned his head to Yin Yuan and said, "Then go ahead, I'll arrange this." ”

Yin Yuan nodded and went upstairs with his memory.

It's a huge, luxurious castle with footsteps echoing as you walk up the stairs.

The castle has four floors, the top floor is for storing some special items, the third floor is for resting bedrooms, and the second floor is for rooms such as study laboratories.

On the second floor, Yin Yuan found the study in his memory, and then knocked lightly on the door, and there was a crisp knock on the door.

"Come in, the door is unlocked. A slightly old and hoarse voice came from the room.

Yin Yuan pushed open the door and walked in, then his face changed, and he gently closed the door with his hand, Yin Yuan looked at this study, on the left side was a large bookshelf that occupied the entire wall, although the top three rows did not put books, but the rest were stuffed with dense books.

Then in the middle is a desk, behind which is a small window, under which is a mural of roses, and on the wall to the right is a fluorescent lamp, literally a fluorescent lamp, which fluoresces in an unknown solid, covered by a transparent lampshade, which brings light to the study.

However, there was one thing missing in the study, and that was what about the Duke of Rose, whom the servant had said before, and there was a response in the door when he knocked on it.

Yin Yuan looked at the desk, there seemed to be something on the desk, and stepped forward, there was a scroll of unknown animal leather spread out on the desk, with bright red words on it.

"My child, when you read this letter, I hope you can pack up your things and return to the capital of the kingdom as soon as possible, the Scarlet Mountains no longer belong to the Duke of Rose, only the devil can survive in this land, the ancient demon has returned from hell again, everything will cease to exist, he is back, go to the capital, there is a royal family and the Holy See, they can resist the devil......" The handwriting behind it suddenly became confused, and it was impossible to understand at all.

Yin Yuan put away the scroll, thought about it, and several mysterious runes flashed in his palm, and blood-colored flames rose, enveloping the scroll and burning it into a pile of black ashes.

"No, if that's the case, it doesn't explain why the Duke is missing, is there anything that can't be said and has to be recorded on the scroll, but, isn't it the same to write it by hand when you meet, isn't it afraid of being seen by others if you write it on the scroll like this. The main thing is who in the room just answered my knock. Yin Yuan looked at the study while thinking.

Walking in the study, Yin Yuan carefully found the other side from one side, but found nothing at all. The inside and outside of the desk, all the drawers, were opened, but an important thing was found, which was an experiment journal pressed under a pile of waste paper, which recorded some of the "special" experiments of the Duke of Rose.

However, these records are somewhat obscure, and at the same time, it can be seen that the back of this journal has been torn off, and the clear tear marks are not hidden in the slightest.

Who could have torn it?" Yin Yuan thought to himself, and then looked at it.

"The one in the underground is already watching my child, there is no way, I have to open the sealed data of the ancestors, restart some experiments that I think can be carried out, record the experiments, and hope that I can solve this problem, and don't pass on this responsibility to the next generation.

11091, the code name of the experiment, the name of the Duke of Rose came to be like this, it is really surprising, but why did I finally stop the Rose experiment, I saw him, he was so charming, I felt free of him, restart Rose.

11092, I'm really crazy, why did I release such an existence, he is so terrifying, although he is harmless to those who have the blood of roses, but those innocent lives, no, I must change all this, what I release, then it is up to me to end.

11101, I did it, Rose succeeded in closing the underground under my control, but Rose needs blood to water, animal blood can, but he seems to prefer human blood.

11106, I executed a criminal, sacrificed him to Rose, oh my God, what am I doing?

......" After flipping through the records in his hand, Yin Yuan also burned the record, and three experiments were written in this record, but did the Duke have a problem with his understanding of the experiment record and diary, in this record, there was no detailed explanation of how the experiment was, but the mental activities accounted for most of it.

Rose, Rose Gold, Life Dao in the Forest, these are the first three experiments of the Duke, according to the records, these are all used to fight against some kind of creature under the Duke's Palace, and they are experiments that began a long time ago with a certain Duke.

The first rose, looking at what is written in this record, should be a rose flower that has become a spirit, with strange powers, and then likes to suck blood, but it is not suppressed in the back, but is eroded by the creature underground.

So the Duke started the experiment of rose gold, which is the emergence of rose currency in the outside world, through the unique rose pattern on the currency, this currency will have the effect of absorbing the spiritual power of the person who owns the currency or what power, and then recycle it regularly, these currencies with power can remove the power of the underground creatures in the rose's body.

However, it still doesn't work, for some reason, the Rose Currency can't become the mainstream currency, even if its price is high on the black market, and there are so few people in the Scarlet Mountains that the recycled currency can only barely resist erosion.

So, the Duke started the third experiment again, this experiment was very bloody, perhaps the Duke is becoming more and more abnormal, the Duke invited the people of the town to build a straight path in the dense forest of the town, on the surface, for the convenience of travel, so the people in the town have helped.

However, this trail is not so simple, first of all, the materials for building the trail are needed stones, these stones are all from the duke, and there is a corpse in each stone, yes, human corpses, animal corpses, countless corpses, some are prison criminals, some are killed after encountering inexplicable dangers in the Scarlet Mountains, and are brought back to the Duke's Palace by Rose, and some are corpses that the duke bought from the kingdom, using special spells, refining them into pieces of stone.
