After nearly ten days of boating or walking, the two of them finally arrived in Einsteburg, a city about the size of Sudi.

During this time, Chris also discovered something interesting, that is, although the creatures of the underworld are different from the extraordinary system of humans, there seem to be many similarities between the two.

For example, some underworld creatures can also precipitate some extraordinary properties after death, but this extraordinary property is not the same as what Chris has seen before.

Perhaps because of the geographical environment, the extraordinary properties of some underworld creatures that precipitate after death not only contain a large amount of dark matter, but also contain some deadly madness.

Chris has experimented several times, and this extraordinary property of the underworld cannot be directly exploited by humans, or even by underworld creatures.

Moreover, the way of promotion of the creatures of the underworld is also different from that of the extraordinary people of humans, there is no potion recipe here, and there is no extraordinary way.

Through the conversation with Merry, Chris knew that if the creatures here want to increase their strength, one of the main ways is to devour!

Devour the bodies and souls of other underworld creatures, and then increase their own flesh and strength.

Of course, the side effect of this is also very big, that is, it is more cruel and crazy, and perhaps in the end, the stronger the strength, the more crazy and out of control in the heart.

Of course, this is limited to the low-level creatures of the underworld, and there seem to be other ways to advance to the higher-level creatures of the ruling class, but this is not what Merry understands.

And after a few days of getting along day and night, Chris also knew some abnormalities in Merry.

Although she has a body very similar to that of a human, there seems to be an ugly and deformed hole in her back, but usually because of the cover of clothing, outsiders can't see the abnormality.

This is also what Chris only found out by chance, but after all, it is the privacy of the other party, and Chris pretended not to know and never asked.

Along the way, Chris also encounters all kinds of underworld creatures.

Some low-level underworld animals even have good spiritual materials on them, just like the transcendent creatures in the human world, except that most of them are dark attributes, there doesn't seem to be much difference.

So along the way, Chris harvested some spiritual materials for various reasons, but he didn't know how to deal with them for a while.

After all, he had just been promoted to "Mechanical Expert" not long ago, and he hadn't played and digested it, so he didn't know how to analyze and purify these spiritual items to remove the dark impurities and crazy factors inside.

Einsteinburg is a city about the size of Sudi, and the distance between the two is not far, because of Chris's appearance, it is easy to take Merry into Einstein Castle.

Entering the streets of the city, because of the gloomy environment of the underworld, the air is always damp and moldy, and there is even some smell of blood wafting from time to time.

Unlike the crimson moon of the human world, there are two pale moons, one large and one small, that hang in the sky of the underworld forever, and only disappear for a brief period of time each day.

Because there is no sun or daylight, these two moons, which are more like the two moons on Earth, become the main illumination here.

I don't know why, Chris always feels that the full moon in the sky is particularly familiar, giving him a long-lost nostalgia.

Perhaps because of the lack of sunlight, there are very few green plants in the underworld, and more of them are some aggressive dark plants, such as the Vampire Grass, the Flower of the Other Side, and so on.

The dark, damp streets are lined with pedestrians, or more precisely, underworld creatures with very different sizes and appearances, and there are very few humanoids like Chris and Merry.

This is also one of the reasons why Merry is a slave, a slave of her appearance and size is very valuable in the underworld.

But the slave marks on her face doomed her to not be able to easily get rid of her slave status and walk and live freely.

Merry led Chris to a gloomy and damp manor, and it seemed that she had been there more than once.

"That friend of yours lives here?" Chris couldn't help but ask, looking at Merry's expectant expression.

Merry hesitated for a moment, then replied truthfully:

"His name is Colby, and he is the steward of this estate, and he is also ...... A good friend of mine used to be. ”

Chris looked at Merry's expression, it seems that he is not just an ordinary friend to be able to come here at this time and in this situation.

After Merry explained the situation to one of the guards outside the door, it wasn't long before Chris saw a young man with a human body and two horns on his head approaching.

The other party was obviously very familiar with Mei Li, even though Mei Li was wearing a black veil now, but he recognized it at a glance.

"Merry?!!Why are you here at this time?Isn't that boss of yours unwilling to let you out easily?"

Then Colby noticed Chris beside Merry, frowned, and said:

"Who is this young gentleman?"

Merry looked left and right, and when she saw that there was no one around, she pulled Colby aside and whispered in his ear.

Chris shook his head a little speechlessly, this is really intimate.

However, his life-saving benefactor is also a little bold, since the other party is the housekeeper here, it is really difficult to protect the two of them, of course, unless their friendship is very deep, so that Colby is willing to take the risk to protect them.

I saw that after listening to Merry's narration, the young gentleman housekeeper looked at Chris with a smile and said:

"I didn't expect you to go through so many things, since you are Mei Li's friend, naturally you are also my friend. ”

As he spoke, Colby naturally hugged Merry's waist and said softly:

"Don't worry, I still have a certain right to speak here, you can hide here for a while, and when this matter passes, I will prepare a new identity for you. ”

Melly hugged Colby with a sigh of relief, and then led by the other party, Chris and Merry entered the dark and damp manor, living in two small rooms in the middle of nowhere.

The owner of the manor seems to be often absent from here, at least Chris has been in for three days, and has not heard of the owner of the manor coming.

During these three days, Chris also understood why Merry was here at this time.

Because during these three days, Chris sensed more than once that Colby entered Merry's room in the middle of the night and then left for a long time.

It is clear that Merry and Colby resemble the relationship between a man and a woman.

But because of the slave imprint on Merry's face, the two of them can't be together openly.
