Looking at the defense line dozens of kilometers away, Olga knew he couldn''t get closer.

    His natural ability reminds him that if he leans further, he may be attacked.

    That line of defense consists of a large number of fortresses and walls connecting them, locking the polluted land constructed by the demons.

    Those fortresses are built every few kilometers.

    It looks like a medieval castle. It is made of white unknown rocks. It is about 200 meters high. It covers an area close to a small town, and a crystal is suspended at the top.

    On its wall stood soldiers with weapons in hand, and there were things similar to arrow towers distributed among them. Olga could smell that every brick and stone was engraved with a large number of magic runes, giving it far more strength than ordinary things.

    Under the energy vision, he can basically see energy fluctuations of different intensity from those soldiers.

    Although most of the strength is not very high, which is just the level of entry, it also shows that they are not very easy to deal with: "it seems that when the demons get together and try to attack the defense line, they will go up and try again..."

    Since the other party can trap all kinds of demons in this area, including many [upper demons], at least there should be no way to get around in the conventional flight, even as for digging holes and transmitting.

    He had no objection to being thrown in by the guys on the other side of the bottomless abyss and asked people to shut the door and beat the dog.

    Because in the current situation, the rest of the world should have been on guard for a long time, and there is no good fruit to eat.

    Moreover, although it is relatively free to be thrown to the outside world, without the blessing of this area, it is also more oppressive in the world. It is estimated that the strength of ordinary demons will be only one tenth or two. Once the position is exposed, it is easy to be chased and beaten by a group of people whose strength is far less than their own, and their death is even more unclear.

    This high-level world has already had a complete system.

    When the upper gods are united, the devil is essentially targeted by the whole world.

    Perhaps the stars in the sky are watching themselves maliciously, and these demons may be. If we don''t make a hole in the existing order first, there is no chance to show our hands and feet at all. Walking alone for thousands of miles is just looking for death.

    [help the demon on carlto''s side expand the space channel.]

    These are the terms set by Olga when he signed a contract with them.

    The help here does not mean that you can count only by directly opening up space channels, but can understand more roundly. After all, being an honest wage earner has no face.

    For example, it is also a kind of help to break through the barrier together, so that many demons can rush out, so that they can more easily collect sacrifices, or open the space channel in other messy ways.

    According to his estimation, as long as he makes some additional contributions when breaking this line of defense, he can basically meet the conditions of the abyss contract and be free of debt. After all, he is only a [median demon], and it is not easy to break through this line of defense alive.

    According to the information he got from the dead not long ago, the gods of the world seem to have reincarnated a batch of the Holy Spirit in their own God''s country decades ago.

    Help the mortal race in this world!

    And many of those reincarnated saints are now piling up in these lines of defense.

    It''s not easy to get rid of them.

    From those broken memory fragments, he roughly judged what level his strength belonged to in the world.

    Except for a few racial elites, ordinary people should not have much threat to him, but the more specific situation can only be known after a formal fight. After all, there will never be few hidden things in this advanced world. In case the other party directly takes out artifacts and other things, the probability of Olga overturning cannot be said to be No. after all, there are big men covering other people''s heads.

    "Huh?"

    Aware of the fast approaching creatures behind him, Olga looked back and found a very thin guy about three meters tall coming towards him.

    He didn''t hide anything, just there without any action, quietly watching each other close.

    When the other party approached a distance of more than ten meters, he clearly felt that the other party had no desire to attack himself.

    So he tilted his head and asked curiously, "what''s up?"

    He could feel that the guy in front of him should be close to the [upper demon], but there was no qualitative change and broke through that bottleneck, so he was still a [middle demon] at the same level as him, and Olga didn''t need to be afraid of any existence at the same level.

    That''s why he let the other party approach.

    The other party looked at Olga in front of him and said with a calm smile: "dear friend, I remember you. You are a demon who has just arrived in the world like me, so I now have a proposal to cooperate with you."

    As soon as he heard the familiar words "dear friend", Olga knew that the other party was definitely a good player to sell his teammates!

    As a demon, I haven''t killed my teammates dozens of times. This name can''t be so skilled.

    But he asked indifferently, "what proposal?"

    The other party explained enthusiastically: "you and I know that although the general direction is to break through that layer of defense, some demons will always look for trouble everywhere, which is determined by the devil''s nature, so I hope to find some demons who can communicate to form a mutual aid association to ensure their own safety."

    In his opinion, he can get close to this distance without showing the desire to attack. Olga should be a relatively easy-going existence.

    Hearing what he said, I don''t know if it was an illusion. Olga felt that the so-called devil looking for trouble should refer to himself. After all, he just wanted to cut a wave of leeks.

    If you can''t kill the enemy, killing your teammates first can also make up for your evolution points.

    But looking at the face in front of him sincerely inviting his opponent, Olga felt it better not to say anything.

    After some reflection, he asked the other party, "how many have you attracted now?"

    "Twenty, we are all demons who don''t want to listen to people, but want to find a safe environment. Their strength is all [median demons]. Everyone should be much calmer than ordinary demons and can basically communicate peacefully!"

    "Well, I didn''t expect that our peaceful demons also have their own organization... Let me join."

    With the idea that he had nothing to do now and could join the fun, Olga finally agreed to the other party''s invitation.

    "OK! Welcome to join me, my friend! You can call me Hart!"

    Although he felt that the other party wanted to stab himself in the back, Olga nodded and said, "my name is Olga. Please take care of me in the future!"
