The underground factory of the smelting yard is far from being as wide as it is on the ground, after all, it is excavated underground, not only a lot more rugged, but also much narrower, perhaps because there is no vent in the depths and the lack of oxygen is insufficient, everyone has attached another state.

Mild hypoxia!

Mild hypoxia will lose two points of health per second, which would kill a person in almost two or three minutes when a person only had nearly 200 health points before the horizon, and now although it still makes people bleed, it will undoubtedly last a lot.

But the strange thing is that the lighting of the candles around them does not seem to have anything to do with oxygen, and they are still jumping and flickering, and the flickering is obviously not caused by the wind and the air currents generated by the actions of the people, but more like they were jumping like this.

"There's no oxygen, how did this lamp burn?"

Someone who knows basic common sense when even asking.

"You should wonder how you can burn for a month without any loss without anyone changing the candle!"

It's full of things that go against common sense, and there are a lot of doubts.

"You two stupid, what's impossible now?"

Someone sneered, what has become of the day now, still talking about the so-called science in the past, it is ridiculous, science can explain all this now? If you can, call the scientist out.

"Be careful, everyone."

Xu Fei carefully ended the noise, at this time it has been a long time since he encountered a boss, and ten captain-level bosses of the same level appeared in a row, making Xu Fei more sure that there is a bigger boss here.

At the very least, there must be the highest level of lord that he knows so far. Xu Fei thought of the fall of the queen ant, and his eyes were extremely excited, the military has greatly increased in this line, and he no longer regards Ji Chen as an opponent at all, after all, even Cao Tian and Jin Feng, whose combat power has faintly surpassed Ji Chen, are not his opponents at all under his full combat power, and when he converts the gains of this line into combat power, not to mention the first-level battlefield, it is estimated that even if he reaches the second-level battlefield, he can dominate one side, although it is a bit blind to say this when he doesn't know the situation of the second-level battlefield, But strong enough to make you fully qualified blind!

"Why is there no underground factory except for nothing?"

Someone couldn't help but finally asked the question that had plagued them for a long time, although the factory on the ground was in disarray, but at least some metallurgical equipment and metallurgical production materials could be seen, and at the moment this underground factory had no hair at all, and there was no manufacturing and smelting equipment. And there is no mine underground, which also excludes the possibility of mining.

"I guess it hasn't been built yet..."

Some people who pay attention to Xicheng know that although the industrial park has been put into use, it has only recently begun, and many projects have not yet been fully completed. The underground factory is an example of this, but the sometimes wide and sometimes narrow roads, as well as the uneven walls, are all manifestations of the unfinished work.

"Look, there's a gate!"

In this originally not very open underground factory, a slightly magnificent gate appeared in front of everyone's eyes, the workmanship of the gate and modern products have a completely significant surprise, the uneven door pattern, and the look gives people an indestructible metal material, immediately make people conclude that this door is not ordinary!

"Hey, anyone? Open the door! ”

The one who moved fast actually stepped forward and began to call the door, but even Xu Fei didn't stop him.

"Idiot..."

Many people looked at this scattered person who went to knock on the door and call for it with idiotic eyes.

Ji Chen also had a posture of watching the show, but he didn't look at this move much, after all, it was not a matter of staring at this door like this, and it was also a good thing to have a "hero" take the lead.

Something unexpected happened, the scattered man who originally thought that rash action would end badly, actually called open the door, only to see that the door made of special materials with special patterns slowly sank into the ground, revealing the three giant beasts hidden inside!

Three Lord-level Mechanical Alien Beasts!

Sculpture, serpentine, ape!

Investigation!

Mechanical Alien (Lord Boss)

Grade: 10

Health: 100,000

Attack:???

Defense: ???

Skill: None!

Description: The highest level bosses on the first-level battlefield, don't think that you don't have skills to underestimate them, they will use terrifying strength to let you know how powerful they are!

At the moment when the door slowly opened, in the last door at the end of the hall, the white bones with glowing green eyes were a little frightened! I thought that this door would be able to deter the offending people a little, but I didn't expect that someone would directly say the correct password, and I came in without any strength?

"Damn it, give me back when you're dead!"

Inexplicably thought of the memories he had gained by devouring the earthlings, and the mysterious being cursed secretly.

"A bunch of little bugs, killing themselves..."

The dark green eyes seemed to see everything outside, and they immediately felt relieved and began to carry out their final transformation, and at the same time, the chain that locked the three lord-level mechanical alien beasts also quietly disappeared!

"Haha, I'm really obedient, let him open the door..."

The scattered man who opened the door, after opening the door, saw three motionless lord-level mechanical alien beasts, and thought that there was no danger, even if he was embarrassed to touch his head. With his attention, it was naturally impossible to detect the movements of the lord-level mechanical alien beast.

"Be careful!"

He didn't notice that naturally someone noticed it, Ji Chen always opened his spiritual eye in this underground factory, and he caught it the moment the carved mechanical alien beast got up, and saw that the "lucky general" was still there and was stunned, when he even reminded him.

"Huh?"

The "lucky general" heard a voice behind him, subconsciously turned around, only to feel a cool breeze behind him, and the whole person flew out upside down and pounced on the crowd!

-1300！

"Alert, alert!"

Xu Fei hurriedly ordered loudly, the movements of the carved mechanical alien beast were only fleeting in his eyes, and he couldn't see the trajectory of his movements at all.

The scattered man flew directly towards the back where Ji Chen was, and a huge hole had appeared on the back behind him, the wound was the size of two fists, and the black iron armor he was wearing couldn't stop the sharp beak of the carved mechanical alien beast at all, and it was directly penetrated, and the whole person directly lost half a life.

"Drunk"

Ji Chen directly poured a bottle of instantaneous life elixir (small) into this "lucky general" and hung his life. The instantaneous elixir of 800 points of blood was really magical, and the lungs that had been penetrated began to recover at an extremely fast speed, followed by cartilage, and then the layers of structure on the back.

"Thank you!"

"Fu Jiang" had a complicated complexion, and when he fell into the crowd, no one caught him, which made him feel cold for a while, and he was obviously worried that he would not be able to catch it, after all, the speed at which he "flew" was too fast.

"I want to pay it back..."

Ji Chen said lightly, such a bottle of instantaneous life elixir was obviously a loss for this buddy directly.

"Definitely!"

"Fu General" nodded heavily, although he is a scattered person, but the strength to be able to participate in this action that can only be participated in by a master is obviously not a mediocre hand, and it is more than enough for military merit to exchange for some instantaneous medicines, what he really thanked was Ji Chen's reminder that made him turn around, otherwise he would be broken now by heart. At that time, it is difficult to say whether he could recover a life.

"Cultivate well, brother!"

Cao Tian also slapped the "lucky general" who was even slightly older than him in the same age, and now that the main lord is coming, they naturally can't stay out of it.

"Hurry up and hold this eagle!"

"Able to control this snake with control!"

"Everyone else, besiege the ape first!"

The carved lord-level boss did not stop after killing and injuring the "lucky general", and directly rushed to the vanguard of fifty people to start the slaughter mode, the terrifying power, and the unparalleled speed were not at all comparable to the captain-level boss before.

Xu Fei immediately made a decision, and a few orders were issued immediately, although the people here were injured a lot for a while, but there were no cases of death, after all, they are not mediocre hands, the average health value is about 2500 points, as long as the head is slightly helped, it should not be killed under one blow.

And after the eagle-shaped mechanical alienation beast moved, the other two lord-level bosses were not slow at all, and the snake-shaped mechanical alienant beast directly dragged its long body and flew up from the ground, and the speed was not only much faster than the black mamba snake in the desert.

"Paralyzing Arrow!"

"Ice Rain!"

Li Kui and Wei Tianya took action one after another, using all the means they could to limit the snake's movements, but as for the eagle, it was not within their consideration.

"Winding!"

"Earth Clay!"

Following Li Kui and Wei Tianya, the rest of the people with a little bit of control also reacted, and with the addition of several controls, the movements of the snake-like mechanical alien beast also slowed down, although the speed was still not satisfied, but it was only between the captain-level boss.

"Thunderstorm!"

Xu Fei immediately gave an order to Lei Feng and signaled Lei Feng to turn on his talent.

Although Lei Feng was very dissatisfied with Xu Fei, he did not hesitate at all, now was not the time to discuss personal grievances, and he immediately turned on his talent.

"Brothers, come on!"

Righteous Breath: Actions and words will infect others, causing them to have a fearless heart and enter a fearless state, in which everyone's attack damage is increased by 10%!

Cao Tian and even Jin Feng joined the siege of the ape boss one after another, and with the blessing of Lei Feng's talent, his combat power was directly close to 5000! With a 10% increase in the group's combat power, it is very useful to deal with this stronger but slightly less fast ape boss, after all, at least the attack hit chance will be high!

"Could it be that I carry this eagle alone?"

Ji Chen's movements are not slow, even a little faster, although he is extremely fast, but in front of this eagle is really not enough, even if he turns on the force speed conversion and the wind of flowing clouds plus ghost steps, it is in vain, only under the additional state of the spiritual eye can he dodge or take a block, but even if he blocks, the terrifying force will also make him suffer some damage. As for asking him to kill the mechanical alien beast alone, he hadn't thought about it at all.

"I'll do it too!"

Just when Ji Chen was alone in the process of fighting with the carved mechanical alienated beast, Tong Tianya also gave up the snake and came directly to help, his talent can help him hit the target accurately, plus the hit rate bonus of the elf bloodline, even the extremely fast carved mechanical alienated beast has to eat his attack steadily, plus fifty armor-piercing arrows, he will be the main output!

"I'll do it too!"

Another voice also sounded suddenly, accompanied by a figure appearing on the body of the carved mechanical alienated beast, and then disappeared and appeared behind Ji Chen, and an explosion exploded on the carved mechanical alienated beast.

It was a thunderbolt made by Fan Yi's subordinates who had used it! After Fan Yi's death, his subordinates fell apart, and the people who made thunderbolts also became free men, and Ghost Li bought several by chance, which can be regarded as not small, after all, he doesn't need to hurt at all, he only needs to be responsible for occasionally diverting hatred. And with his teleportation skills, even the extremely fast carved mechanical alien beast is difficult to match.

Since then, the three lord-level mechanical alien beasts have each faced opponents, and the scene seems to be very favorable to everyone!
