In the sky above the Underground City, Zhou Hao, who was wearing silver armor, flew for about half an hour before discovering a strong reaction from the “essence iron mine”! Zhou Hao followed the detector and arrived in a dilapidated house.

As the detector extended to a range of 9,000 meters, Zhou Hao discovered a lot of text and some armor made of “essence iron”. In just ten minutes, Zhou Hao had stored all the precious materials and the ancient text in a special backpack. He also recorded all the ancient texts. He had also sent them to the frog.

Suddenly, the detector emitted an ear-piercing alarm! It trembled. “From the reaction of the detector, there must be something valuable in this room,” Zhou Hao said in surprise.

Zhou Hao gently pushed open the door and entered the room to look around. Finally, the detector pointed at the floor under his feet. “Hai!” With a loud bang, a bottomless hole was suddenly torn in the floor. Zhou Hao’s helmet automatically opened for him to check. “My goodness, this… this… this is actually… Heavens, I’m going to be rich!” Mountains of ‘super essence iron’ appeared in front of Zhou Hao.

“With those miners, it seems that even if they have a large number of ‘super essence iron’, they still won’t be able to transport it away. Hehe, it just so happens that I got a huge bargain,” Zhou Hao said with a smile.

“Zhou Hao, I know you’re very happy, but calm down first. Look carefully and see if you can find ‘essence iron crystals’ here. Compared to ‘essence iron crystals’, ‘essence iron’ and ‘super essence iron’ are basically mud!” the frog reminded.

After Zhou Hao heard this, he calmed down a lot. What the frog said was indeed very reasonable. If he could find “essence iron crystals”, it would be best. After all, even a third-stage Saint Realm martial artist would find it very difficult to damage essence iron crystal. It was very easy for Zhou Hao to drill into the soil, but it was still more or less a little difficult for him to drill into this small mountain of essence iron. It was just like how ordinary people would have a hard time trying to build walls with their bare hands. Sigh… it was as difficult as ascending to the heavens!!

On second thought, why not shrink this small mountain and put it in his backpack? If so, it would be his to do as he pleased! Zhou Hao turned around and took out a small gun from his backpack and fired at the small mountain. With two gunshots, the countless iron mountains were instantly put into Zhou Hao’s backpack.

As the “iron” mountains in front of him disappeared, Zhou Hao discovered that there was actually an extremely huge and firm iron gate built with iron behind the “iron” mountain. Looking at the thick iron gate, Zhou Hao waved his laser saber and slashed at the iron gate. The iron gate was actually slashed apart like tofu and a hot saber mark was left on it. Then, the iron gate beside him fell to the ground.

Under the light, a pile of metal in the distance revealed a silver-blue light, making it appear incompatible with the surrounding environment. This piqued Zhou Hao’s interest. Zhou Hao quickly went forward to check. After scanning with the device, he found that this was an “iron crystal”. In the instant that Zhou Hao entered the slumbering memories of the Ancestral Physique, he quickly found all the information regarding iron essence.

He said with certainty, “Iron crystal! Heavens! I finally found it!” Zhou Hao shouted excitedly.

The frog controlled the flying device under Zhou Hao’s feet to go forward and check. “These ‘essence iron crystals’ are about 50 cubic meters and weigh a total of about 14,000 tons.” The frog added, “If you subtract the more than 12,000 tons that the void beast needs to devour, you will only be able to keep about 2,000 tons.”

“The peak bloodlines of the giant beasts in this universe are really too freaking abnormal! I’m really impressed by the Void Beasts’ appetite! Isn’t 1,200 tons a day too much?” Zhou Hao said with a bitter smile.

“Although this void beast doesn’t devour stars, it is still very demanding. It devours a lot every day… To put it bluntly, even your superior, Ji Yaoyue, is not enough for it to eat its fill!” the frog said with a smile.

Zhou Hao blushed in embarrassment.

If Zhou Hao was willing to grow at the slowest speed, it would help him reduce a lot of expenses. However, if he wanted to grow quickly, just buying those pure metals, ores, and crystals was a huge sum.

Zhou Hao felt a headache when he thought of the problem of money. Although he also had a small sum, it was still not enough compared to the price of the crystals. Helpless, he could only continue to search and see if he could get the heavens to take care of him.

He also discovered some “metallic iron crystals” of different sizes in some decaying houses. Clearly, these had been deliberately kept at home by the miners. Although the gains were very small every time, he still accumulated a lot. In total, there were at least 20 million tons!

There was actually a basement in one of the decaying houses. When Zhou Hao went to the basement, his eyes widened. A huge door that was made of “essence iron crystals” and weighed several tons appeared in front of him! Zhou Hao immediately pounced over like a wolf or a tiger.

“A door made of ‘essence iron crystals’? Does this family have no place to spend their money? It’s fine, baby! Come to my backpack and let me unleash your greatest value!” Zhou Hao directly put the several tons of ‘essence iron crystals’ into his backpack and said with a guilty conscience.

Then, Zhou Hao quickly stepped forward and said loudly, “Wahahaha!!! This family is so rich!!! They must have a lot of treasures!!! I feel that I have an obligation to not let them waste their treasures!!!”

“You… why do I feel like you’re planning to rob their ancestral grave…” the green frog complained.

“Not true! I’m clearly cherishing their resources! This is proof of my high EQ! Tch! What do you know? Forget it, I’m going to continue exploring!” After Zhou Hao finished speaking, a burst of laughter gradually disappeared into the basement.

“Wow!”

Ten minutes later, Zhou Hao discovered a large number of weapons that had gradually decayed as time passed! The number of weapons he found here had already far surpassed the number of weapons Luo Feng found that time in the warehouse! Moreover, in the center of the dark blue metal, there was a pure blue metal ore! Around it was a large amount of dark blue metal that occupied the largest space.

The frog immediately became restless when it saw the pure blue metal ore. Because of the magnetic field of the huge pit and the fact that the ground was not suitable for the frog to control the Luo God Warship, the frog could only control Zhou Hao’s flying device to make judgments through the mechanical eyes of the flying device and collect a large amount of information.

“This is actually! It’s ‘essence iron mother’! It’s an existence that’s even higher than ‘essence iron crystal’! ‘essence iron mother’!!!” the frog said in surprise.
