The situation on the 17th floor of the underground city is similar to that on the 16th floor.

Although the cultivation of the new killer is stronger and stronger, it is still far from Cheng Feng's opponent.

It didn't take a minute, and the seventeenth floor was cleaned up.

Then Cheng Feng stared at the last floor of the underground city.

"Block it, everyone block it!"

"Some people dare to step back and die!"

The 18th floor of the dungeon is full of loyal newcomer killers.

At the same time, there are about 20 killer mentors.

These more than twenty killer tutors, with high accomplishments, hid in the crowd and roared.

Order all the new killers to block the entrance and intend to block Cheng Feng's steps with a human wall!

However, the iron wall can't stop Cheng Feng's pace.

How can a mere newcomer killer be stopped?

"Those who don't want to die, get out of the way!"

Just listen to Cheng Feng's burst and drink, Deng Deng

Like a human Tyrannosaurus Rex, the whole man rushed straight to the 18th floor of the underground city.

Keng Keng!

Seeing Cheng fengchong coming, countless killers attacked.

Sword light, sword strength, gun awn... All of a sudden, he greeted Cheng Feng.

But he didn't hurt Cheng Feng's hair.

When Cheng Feng rushes near, Bang

Directly hit the group of people standing in front of the entrance and flew away in an instant.

Then Cheng Feng's castration did not decrease, bang bang!

I only heard a burst of broken bones and flesh with sour teeth. I don't know how many killers were hit by Cheng Feng, collapsed their chest and broken their bones. The whole person was killed alive!

"Damn it, damn it!"

"Cheng Feng is so strong that these wastes can't be stopped!"

"What should I do? What should I do now?"

Seeing Cheng Feng's outrageous rush into the 18th floor of the underground city, the remaining killer tutor was cold.

A sense of death rushed forward, as if it would die the next moment.

"Everybody, use the serrated eye!"

"For today's plan, only by using the serrated eyes can we have a glimmer of vitality."

"Otherwise, the whole new base will be destroyed by Cheng Feng!"

"Well, I agree."

"I agree!"

At a critical juncture, a white faced killer tutor made suggestions.

All of a sudden, all the killer instructors agreed.

Because at present, the only thing that can save their lives is the serrated eye.

"Now that you have made a decision, let's do it!"

The white faced killer glanced at the middle-aged man, left a word and immediately flew to a cabin located in the corner of the 18th floor of the underground city.

The others saw it, without any hesitation, and flew to the cabin.

When more than twenty killer mentors all entered the cabin.

Kaka, Kaka

A burst of mechanical friction sound of dental acid suddenly rang through.

Then, such a big underground city began to shake violently.

Like a magnitude 10 earthquake, the whole underground city has an illusion of disintegration.

"What happened?"

Seeing this, Cheng Feng, who is chasing the killer mentor, couldn't help frowning.

"Cheng Feng, it's those remaining killer tutors who are playing tricks."

Long Aotian's voice sounded: "I saw those guys drill into a wooden house, and then the underground city shook."

"Nine times out of ten, it has opened some kind of life-saving card!"

Hearing the speech, Cheng Feng blew more than a dozen new killers in front of him.

When I looked up, I immediately saw the earth flying all over the underground city.

Large bricks and tiles of the city wall fell to the outside of the city, revealing the dark and shiny metal luster inside.

At the same time, the harsh sound of mechanical friction became louder, like thousands of broken iron pieces rubbing against each other, which made people feel very uncomfortable.

"Long Aotian, those killer tutors, may have opened a mechanical device."

Seeing this scene, Cheng Feng guessed, "this mechanical device is very large. It is estimated that the whole underground city is built on that mechanical device."

"So when the mechanical device is turned on, the whole underground city will shake and even collapse directly!"

Cheng Feng's analysis is very accurate.

His voice just fell, Hua la

Such a big underground city split from the middle in the midst of shaking mountains and earth.

Large walls collapsed and houses collapsed.

Many unsuspecting killers were buried under the collapsed city walls.

"Holding grass is really a mechanical device."

Long Aotian and Xiao Jin flew away when the dungeon collapsed.

Under the crumbling dungeon, a powerful mechanical arm suddenly stretched out.

The reason why the underground city collapsed just now was caused by the impact of mechanical arms.

I couldn't help but wonder, "when did the mechanism technology on the earth dome become so powerful?"

"Can you make such a powerful mechanical puppet? The combat power is almost comparable to the strong man who ascended to heaven!"

Obviously, the mechanical puppet hidden at the bottom of the dungeon is a creation of mechanism art.

Only mechanism can make steel, wood and other objects into dynamic mechanical puppets.

However, in the earth dome, even the Gongshu family and the Julu family, who are most proficient in mechanism skills, can not produce mechanical puppets with combat power comparable to the four or five times of going to heaven.

"This may be the ultimate mechanical puppet."

Cheng Feng was also surprised. He had a flash of light in his mind and thought of a possibility: "it is said that Gongshu family and Julu family are secretly studying a kind of mechanical puppet whose combat power can catch up with and surpass the experts in heaven."

"They call this mechanical puppet the ultimate mechanical puppet."

"It is said that it is very difficult to study the ultimate mechanical puppet. 99% of them are defective products and have never really succeeded in making one."

"Now it seems that these two organs families not only succeeded, but also sold them to hell gate!"

Cheng Feng had contact with the ultimate mechanical puppet more than half a year ago.

At that time, he also obtained the ultimate mechanical puppet of a defective product, and his combat power reached the peak of the broken environment.

No process peak put it in the Cheng family and didn't take it with him.

"The ultimate mechanical puppet?"

Hearing Cheng Feng's words, long Aotian couldn't help but burst out: "nest rely, the two abnormal families of public defeat and Julu are really powerful enough."

"Even such superb mechanical puppets can be made!"

"It seems that the Tiangong company of the eclosic dynasty may really hope to succeed by inviting the elites of these two families to join and study the super killing weapon."

"At that time, it will change the whole war situation!"

The reason why Yuhua shenchao ordered Tiangong to set up a team to study super killing tools must also be inspired by the ultimate mechanical puppet.

Otherwise, we will never dare to put the chips that determine the outcome completely on the super killing weapon.

"Long Aotian, don't say this first, save people first!"

At this moment, the whole underground city has completely collapsed.

Those new killers were killed and injured in the sudden disaster.

In particular, the killers on the first few floors of the underground city are only children, weak cultivation and human nature.

Save it, there is great hope to recover.
