Boom~

With a flying leg, the mechanical maintainer kicked Zhu Yan three or four meters away, and the huge grizzly bear body rose into the air, slammed into the ground, and then slid on the ground for a distance from the boss;

In order not to harm the bookshelf, the maintainer put away the blade and switched to his fist, which was more powerful;

Zhu Yan shook his head, his head was clouded for a while, he felt a little dizzy, his whole body ached, his bones seemed to be broken, the defender's knife technique was as fast as thunder, and his fist technique was faster than his knife technique, Zhu Yan was a little blindsided for a while, and he felt as if he was fighting to the death with a martial arts master, and the other party only attacked but not defended, and Zhu Yan who fought had no temper at all;

Dark Raptor Strike from above!

Zhu Yan commanded the Dark Raptor to pounce on the mechanical maintainer and immobilize it;

It was difficult to dodge the high-altitude dive, Zhu Yan took advantage of the mechanical maintainer's immobilization, and hurriedly cast the strong concealment skill, disappeared, and then summoned the deadwood warrior and pounced on the mechanical maintainer;

Zhu Yan rushed towards the outside of the library, and the sound of a fight between the Deadwood Warrior and the Mechanical Maintainer was heard behind him, and the sound faded away, in Zhu Yan's summon interface, the Deadwood Warrior's HP continued to decline, and after thirteen seconds, the Deadwood Warrior's HP was cleared;

At this time, Zhu Yan had already left the library for hundreds of meters, and had already left the warning range of the mechanical maintainer, Zhu Yan guessed that the warning range of the mechanical maintainer could only involve the entire library at most, as long as he left the range of the library, he could get out of the battle;

However, for the sake of safety, Zhu Yan still left the library a hundred meters away before daring to gradually stop;

From the time Zhu Yan entered the City of Machines to the present, all the monsters he has encountered are elite-level monsters. Not a single ordinary monster;

These monsters, if you just encounter one, it's okay, once the battle is too long. will attract other monsters and fall into siege, and more, like mechanical maintainers, Zhu Yan is not an opponent at all, and he can only run away when he encounters it;

This kind of dungeon difficulty has completely surpassed the difficulty of ordinary single-player dungeons. It's almost comparable to a copy of the difficulty level zhu yan is very depressed and. He finally understood why the mayor of the town hadn't explored the entire city of machines in the first place;

Weaving through the streets of the city of machines, which looked empty, after a while, the sky was originally gray. It began to rain lightly. The cold rain hit Zhu Yan's face, and the chill was clear, which shocked Zhu Yan's spirit;

"No, there must be something I overlooked, a dungeon of this difficulty is at least an epic quest, and the exploration quest given by the mayor is only a silver quality quest. That's not right, there's a problem! Zhu Yan wiped the rain from his face. frowning and thinking;

Zhu Yan's eyes crossed the high-rise buildings and looked at a classical-style temple in the deepest part of the Machine City, which was the only building with a unique architectural style, Zhu Yan knew that there was a god created by the ancient goblins themselves, and it was also the biggest boss in the copy of the Machine City, as long as you killed it, you could clear the level;

But now Zhu Yan doesn't even have a way to get close to the temple, as long as he goes deep into the Machine City, he will encounter the resistance of elite-level monsters, making Zhu Yan tired of fleeing for his life;

Wandering aimlessly, Zhu Yan wanted to quit the dungeon directly several times, anyway, he had already obtained a drawing of the frost trebuchet, and it was not a trip in vain, as for the task of the mayor, he could only give up;

However, if he gives up the exploration task issued by the mayor, the cute mechanical ball on his shoulder will also be returned to the mayor, which makes Zhu Yan a little reluctant;

"No, no, there is a problem with your equation, the result of the calculation has a fatal flaw, you can't continue, you have to overturn the calculation and start over!"

"Hahaha, haha, you blasphemers, you will all die, you have harmed everyone!"

……

A voice came from the room ahead, low and full of madness;

This room, a low bungalow, was somewhat out of place with the nearby buildings, the gate was broken, scattered on the ground, an ancient goblin ghost, lying on the ground, constantly scribbling on white paper, the ground beside him, covered with white paper, depicting a mess of symbols that made people dizzy;

Zhu Yan's eyes lit up, and those symbols looked somewhat familiar, similar to the ones that had appeared on the drawings of the Frost Trebuchet;

Zhu Yan looked at the ancient goblin ghost, and the other party's name, on his head, was friendly green letters;

NPC: Thor

Zhu Yan hesitated for a moment and walked towards the goblin ghost;

The goblin ghost raised his head and glanced at Zhu Yan, his eyes were indifferent, as if he was a stagnant water, he didn't show any surprised expression at Zhu Yan's arrival, and he didn't like other goblin ghosts, as soon as he saw Zhu Yan, he wanted to rush towards him, wanting to kill him;

This goblin ghost looks very old, with gray hair and beard, looks like it hasn't been cleaned in a long time, all the hair is tangled, and the beard is even more sloppy, looking like a wanderer;

"Hello!" Zhu Yan greeted him, stood three or four meters away from him and stopped, although the other party's name was green,

"That scout ball, I made it when I was thirteen!" The ancient goblin ghost looked indifferently at the mechanical ball on Zhu Yan's shoulder and said;

Zhu Yan was a little embarrassed, this mechanical ball was obtained by the mayor from the City of Machinery, but he didn't expect it to be the other party's item; Perhaps this ancient goblin ghost will think of himself as a thief;

As a result, the ancient goblin ghost, after saying this, turned his head again, continued to spit on the paper, and the expression on his face gradually changed;

"That's it, it should be like this, my calculations are correct, you are all wrong, wrong!" The expression of the ancient goblin suddenly became hideous, and he suddenly grabbed the white paper on the ground and began to tear it desperately;

"It's useless, it's useless, everything is already doomed and irretrievable, the fate of the goblin clan is irretrievable, woo~" The goblin ghost fell on the ground and cried loudly;

The goblin ghost cried very sadly, and Zhu Yan stood next to him, not knowing what to do for a while;

"Maybe it's a side quest!" Zhu Yan thought in his heart;

It took a long time for the goblin ghost to stop crying, and the look on his face became indifferent again;

"What's your name, Outsider!" The goblin ghost suddenly asked;

"Dark Flame, you can call me Dark Flame!" Zhu Yan hurriedly said;

"Darkfire, very well, my name is Afaris, Kulisos, Tuva,......, you can call me Thor;" The goblin ghost uttered a long name, and there were at least dozens of syllables;

The longer the name of the ancient goblin, the more noble his status among the goblins, and the ancient goblin on the other side who called himself Thor was obviously the nobility of the goblin clan;

I just don't know why Thor, who is an ancient goblin nobleman, would appear in such a humble room;

"Young man, why are you in this great city of machines!" Thor the Goblin Ghost asked in a low voice;

"I'm here to explore this city of machines;" Zhu Yan said;

"Hehe, exploration, outsider, I can feel that there is great power in you, but with this power, it is obviously not enough to explore in the city of machines;" Thor chuckled under his breath;

"So, can you help me?" Zhu Yan opened his mouth and asked, obviously, this NPC will not appear here for no reason, there must be a reason for his appearance, and Zhu Yan faintly feels that this NPC may be the reason why it is so difficult to solve this level forty copy;

"In this world, there is no free lunch, if you want to gain something, you will definitely lose something, young man, if you can do me a small favor, then you can also get some help from me!" Saul smiled slightly, looking at Zhu Yan with flickering eyes;

"Can you tell me what I need to do and what kind of help you can give me!" Zhu Yan asked;

"My request is simple, all you need to do is enter the largest building in the city and kill one of the guardians inside;" Thor the Goblin Ghost said;

The largest building, that's only the temple, the guardian of the temple, this goblin ghost, is it the final boss of the dungeon, the god created by the goblin clan themselves?

It's just, why would he make this request, how could the goblin clan want to kill the gods they created!

"Are you talking about the god in the temple?" Zhu Yan asked tentatively;

"Gods? God, haha, what a god, it's a demon, it's a demon out of hell, it has destroyed the entire goblin race, making the goblin clan a slave of other races, how can it be a god of the goblin clan! Thor's expression became hideous, and he yelled frantically;

"So, if I accept your assignment, what help will you offer me?" Zhu Yan was unmoved by Thor's crazy expression and continued to ask;

Hearing Zhu Yan's question, Thor suddenly became calm;

"Young man, do you think that the mechanical beasts in this mechanical city are a little outrageously strong?" Thor asked suddenly;

Zhu Yan's heart moved, and he hurriedly said: "Yes, I once met the mechanical beasts you said, they are indeed powerful, can you tell me, what is the reason for this?" ”

Thor looked at Zhu Yan with a smile and didn't say a word;

After a while, Zhu Yan finally understood, and said helplessly: "Okay, I accept your task, now you can tell me the reason; ”

Zhu Yan's purpose for coming here is naturally to clear the customs, and now he has one more task to kill the final boss, which is equivalent to doing a task and getting two rewards, and he is naturally very willing in his heart, but of course, he can't show it on his face;

"Little guy, the reason why these mechanical beasts are so powerful is because there are three strengthening towers in the entire mechanical city, and it is precisely because of these three strengthening towers that envelop the entire mechanical city that the mechanical beasts in the entire city will be so powerful!" Thor said slowly;

"Fortify the Tower!" Zhu Yan was overjoyed in his heart, he finally saw the hope of completing the task; (To be continued......)
