“The Machine Race is stronger than any other race in terms of technology.” The frog hurriedly added, “Humans can’t compare to them either. Humans can only rely on evolution to survive until now. The Machine Race is an intelligent life form. Although they don’t have a soul or human emotions, they still have invincible combat strength.”

Zhou Hao pondered carefully and seriously. “It’s just like Thousand Feather Armor. Although it has emotions similar to humans, it’s still only an intelligent life form and does not have a soul. However, despite this, the Machine Race can still create immortal experts. In terms of technology, the Machine Race is indeed very powerful.”

Hu! Hu! Hu!

A violent wind whistled past, sweeping up sand that was like sharp blades that slapped fiercely onto Zhou Hao’s body. “Frog, do you know? Although the Machine Race is very powerful, we humans also have very powerful strength. We have ’emotions’, something that the Machine Race can’t understand no matter how hard they try.”

From Zhou Hao’s firm gaze, it could be seen that he loved his mother planet, Earth. Suddenly, there was a light not far away.

“Activate the detection system. Probe about 100 to 400 meters ahead and see what that is,” Zhou Hao said cautiously as he looked over.

After the sizzling sound, the frog said in surprise, “Meteorite discovered! That’s what you humans call iron essence!”

Zhou Hao immediately had mixed feelings. Now that he was also considered a planet-devouring entity, it should be easy for him to devour B-level essence iron. However, there was a lot of essence iron in this essence iron mine.

It was already considered lucky for such a large essence iron mine to have even one ten-thousandth of an iron crystal.

From this, it could be seen how precious this essence iron was. The price could be imagined! Just a small piece of essence iron fragment could already make countless overlords fight like crazy.

The frog added, “The buildings in these huge pits had a certain isolation detection effect. The area they enveloped could not be detected or known. However, below their intersection, I was able to detect faint traces of a city.”

“What the hell? An underground city? An underground city built inside the moon?” Zhou Hao did not dare to believe it.

Zhou Hao looked around as he walked. He estimated that there were no living beings within a hundred meters. He entered the cave under the ground and found the Underground City. This place seemed to have suffered an attack.

In a dark corner of the underground alley, a pair of red mechanical eyes stared deeply at Zhou Hao.

With a cracking sound as if something had been activated, Zhou Hao noticed that someone was in the dark. He immediately soared into the sky and erupted with the bloodline of the Ancestral Physique. Just as Zhou Hao landed, two black robots appeared out of thin air in front of him and punched him heavily!

Zhou Hao hurriedly blocked and was almost unable to withstand the force. “This strength… cough! cough! cough! I definitely can’t beat either of them. In the current situation, I can only retreat first!” As he escaped, he discovered a tunnel that led him deeper into the depths of the moon. Zhou Hao directly jumped up and adjusted his posture in the air. He then slid down into the entrance of the tunnel.

“Zhou Hao! Are you alright?! Hold on first! I’ve already sent the flying device out! It’s heading towards you!” the frog said worriedly.

“Hu! Hu! Hu! Ahem! Ahem! I’m fine. Fortunately, they’re too big and can’t enter for the time being. Otherwise, I would be done for.” After Zhou Hao rested for a moment, he was shocked to discover his current location.

There were mechanical factories everywhere here. On careful look, these factories were assembling the very same robots that had just attacked him! “Damn! What’s going on?! Isn’t the outside in ruins?! Why is this Underground City still operating?”

Zhou Hao hurriedly used his “mental detection” to see if someone was doing this on purpose, but there was no one here at all.

Zhou Hao calmly analyzed and guessed that since there was no one here, it meant that the factory here had been automated. Looking at the surrounding environment of the factory carefully, it indeed seemed like the defense here had been ruined because no one had repaired it for years. However, at the very least, it could defend against a planetary attack.

“Phew… Fortunately, these robots aren’t like the guys outside just now. They weren’t injected with chips. Otherwise, I would really be sending myself to the wolves.”

With a bang, the two black robots rushed over one after another. Because Zhou Hao was wearing the Thousand Feather Armor, he forcefully resisted this sudden collision!

“You’re… pretty ruthless!” Zhou Hao cursed.

“Zhou Hao, run! Listen to me! There’s an endless supply of robots in this underground city. But you probably already saw them, right?” the frog said anxiously.

“Nonsense! Do I need you to tell me this?! Let me ask you, what should I do to get rid of this robot?!”

“Follow the route I sent you and go to the energy point to destroy the energy supply there!” the frog said.

Zhou Hao ran back and forth along the route map in the Underground City and quickly discovered some places with thick metal pipes.

“I’ve already found their energy supply. Tell me quickly, what should I do?” Zhou Hao asked anxiously.

“Calm down. First, wave your right hand and take out the laser saber. Then, gather the power of your Ancestral Physique in your right hand. You know what to do next!” the frog said.

Just as the two mechas were about to smash Zhou Hao into meat paste, there was a whoosh! Clang! The incomparably ferocious mechas just now were instantly cut off by Zhou Hao’s right hand.

The two mechas instantly exploded in the air. Zhou Hao jumped up angrily and wielded the laser saber as he slashed fiercely at the energy supply! With a loud bang, the energy supply was completely destroyed! In just a few minutes, the energy supply of the entire Underground Base fell short.

The moment the energy exploded, Zhou Hao stepped on the flying device and flew out of the range of the explosion.

“There must be something important left behind by the miners here to allow the energy supply here to operate normally. Not to mention, these robots must have done this to prevent others from discovering the treasures here.”

Zhou Hao stepped on the flying device and kept flying around. “If I’m not wrong, with the conditions of the collection equipment around here, those miners should have dug up the ‘essence iron’ and stored it carefully. Coincidentally, these robots had forced me to come here. If I don’t compensate myself, I would have been beaten for nothing!”

Then, Zhou Hao increased his search. He immediately began to search the sky above the Underground Base!
