After a period of fighting. No, a one-sided slaughter, Zhou Ming's team finally cleaned up all the robots.

In this battle, Zhou Ming was promoted to level 6, Galen was promoted to level 6, and Rexai naturally became level 6 with Zhou Ming.

Zhou Ming and the others were standing at the underground exit of the robot at this time, observing below.

"Let's recover from here, and then let's go in from here to find out, I always feel that this is like a shortcut to the inside of the ruins!" Zhou Ming and a group of healing techniques recovered the state of everyone.

"Okay, then let's go quickly! You have to enter the ruins faster than others to explore, so you can gain more!" Ma Jianjian said refreshedly.

"Hmm!" the Celestial Fat Star agreed.

Everyone jumped down the huge opening in the ground and walked down the rocky slope, since the robot came out of here, then follow the entrance to find it, maybe it can really go to the inside of the ruins.

After about 100 meters of downhill, everyone came to a deep underground passage, and the passage was pitch black.

Tiansha Fat Star controlled his golden sword to levitate above everyone's heads, emitting a faint golden light that illuminated the surrounding space.

The sword light gradually brightened, and the appearance of the passage was gradually revealed in front of everyone's eyes.

The passage is made of golden rock, which is supposed to be artificial, and the walls around it are very smooth and polished.

The passage is spacious enough to accommodate more than 10 people walking side by side, and is also about 2 people tall, and from the direction, the passage stretches towards the mountains.

Unfortunately, with the light of the flying sword, the distance as far as the eye could see was only ten meters away, and it was impossible to see how deep and far this passage was.

"Do you need me to adjust the highlights?" said to the crowd.

"No need! more than ten meters is enough, besides, you must be constantly consuming, and you can't increase your continuous consumption, after all, the energy you consume, my healing technique can't recover." Zhou Ming refused.

"Well, I don't know what unknown dangers will be next, but I need to retain more strength in order to deal with it in time!" Tiansha Fat Star also agreed with Zhou Ming's opinion.

Everyone walked vigilantly for about ten minutes, and suddenly their eyes suddenly opened up, as if they had come to a slightly larger hall.

More than a dozen doors were opened around the hall. For a while, everyone was stumped.

"Why don't we split up?" Ma Jianjian proposed.

"It's really time-consuming for us to go one by one, so let's do it! Galen follows Ma Jianjian! Rexai follows Daxing! If there is any situation, I can communicate with them telepathically at any time!" Zhou Ming took the words and thought about it, and decided.

Seeing that there were no objections, everyone split up and walked in.

Without the sword light lighting of the Tiansha Fat Star, Zhou Ming was quite uncomfortable.

I saw that he took out Li Qing's soul and spent 10 points of energy to crush it. Now it's much more convenient to distinguish the position by listening to the voice!

After walking for about half an hour, Zhou Ming was finally blocked by a metal door.

Well, this turned out to be an electronically unlocked metal door!

Looking at the slightly dusty display screen next to the door, Zhou Ming was a little speechless.

Zhou Ming walked to the display screen, he knew that if he had to enter the password, the correct door would open. This looks like it's going to end!

The display screen seems to feel the creature approaching, and gradually lights up, showing a 9*9 square nine-square grid.

There are some numbers scattered in the nine-square grid~ Is his sister Arabic numerals?

This!This!Nima is a Sudoku disk?

"Players need to deduce the numbers of all the remaining spaces according to the known numbers on the 9×9 board, and satisfy that each row, each column, and each thick line contains 1-9 numbers, and does not repeat. Zhou Ming's ears seemed to sound the voice of the computer narrator who used to be bored and do Sudoku games.

"Damn, this kind of thing that any normal person can solve with a little time, right?" Zhou Ming complained secretly. It's really cheap for yourself.

Then it took him more than two hours to fill in all the numbers, and he bragged about this IQ......

"Click~!" the metal door slowly parted left and right.

"Yay" Zhou Ming jumped up and quickly ran in. The metal door at the back closed slowly! But Zhou Ming's focus was not here at this time.

"Did I run the wrong channel and come to the sci-fi area?" Looking at the huge steel city in front of him, Zhou Ming was stunned!

Zhou Ming was in a huge underground metal cave with a radius of more than tens of thousands of meters.

From the moment you enter the door, everything around you is made of metal paving, the floor, the rock wall, and the roof of the cave. All of them are metals covered with various furrow-like patterns.

Directly ahead, a city of countless metal buildings spliced together into a giant fortress, the city is extremely dead and silent, without any light. The only source of light is the gemstones set in the surrounding metal walls.

The metal walls are inlaid with a glowing gemstone every few meters, and from a distance, it is densely packed!

The gems were not added by the builders, but were later embedded by external forces!

Each gemstone has some cobweb-like cracks around the perimeter of the metal!

If all the gems were dug up and sold, it would be worth a lot of money, right? Zhou Ming began to happily fantasize about the life of spending money......

No, how can you think of such a vulgar thing now!

There must be something better in such a big city......!

Zhou Ming was very disappointed, took out a roast chicken from the token and walked while gnawing on it.

It has been more than 2 hours since I entered the city, and I have been walking around the city for half a day, except for broken copper and iron, I have not found anything valuable!

It's not a city at all, it's a robot factory! It's a robot factory full of holes!

The smashed robot warehouses, the broken assembly lines, and the scattered parts all show that it is a factory or a broken factory that has stopped production! The robots that deal with them should all be made from here!

Look at these dilapidated buildings, forget it, go straight to the center of the factory and look for it!

After walking for twenty minutes, Zhou Ming came to the center of this huge factory, and a large mechanical control room appeared in front of him, the size of a football field. The walls of the control room were damaged in several places, and the 50-centimeter-thick metal section was exposed, revealing some broken metal wiring.

Zhou Ming knocked on these metals, they were very hard, many times harder than those robots before anyway, I don't know what kind of attack they encountered to be punched out of so many large and small holes.

Zhou Ming found a big hole and drilled in, and saw a row of consoles about ten meters long and countless buttons at the top on the left.

So, he ran over and pressed it all from left to right!

"Woo~~Boom!" The sudden sound broke the dead space. also scared Zhou Ming, who was working hard!

Turn your head to find the source of the sound. I saw a transparent cylindrical space in the middle of the control center light up!

A space the size of two people, a circular glowing ground below, a small space that is completely transparent, and a sliding transparent door.

This is obviously an elevator!
