Mars, an underground steel city. Pen, fun, pavilion www. biquge。 info

"This underground steel city is really big enough. "Lin Feng, who was dressed in black armor, swept his spiritual power in all directions, searching this ancient underground city.

Under Lin Feng's spiritual power induction, some streets, buildings, and so on in this underground city have some words on them! Words are the 'universal language of the universe', through words, in just a moment, Lin Feng can easily find the important place of the entire steel city-the warehouse where the raw materials of the dark iron are stacked!

Lin Feng landed in front of the huge warehouse base, only to see that the warehouse base in front of him was filled with a large amount of dark iron, like a small mountain, not only the inside of the huge warehouse, but also the courtyard outside, and even piled up outside the warehouse compound.

"It seems that those miners were trapped on Mars at the beginning, and even a large amount of dark iron could not be transported away. On the contrary, the dark iron is the least valuable, and the entire steel city is built of black iron, so this warehouse is stacked casually. Lin Feng looked at the hill-like Xuantie in front of him and said with a smile.

"Although these dark irons are only A8-grade metals, they are very large! I don't have a weapon of my own, which can be used to refine weapons. Lin Feng's mind moved, and he began to collect these Xuaniron with the Space Ring. His space ring is very large, with a length, width and height of nearly a thousand meters, in terms of space, it is huge, and there is no need to worry about not being able to put it down.

"Whew, Whew——"

Disappear a whole bunch of darkiron, and then disappear a bunch of ......

Lin Feng collected it quickly. The mountain of dark iron disappeared at a clear speed with the naked eye, quickly disappeared into a pile, and disappeared again and again, and in just a moment, the entire outside of the warehouse, including the hill-like dark iron piled up in the huge compound, was all included in Lin Feng's storage space.

"Well, a total of 118 million tons. Lin Feng smiled and strode towards the warehouse in front of him.

All the black iron that obstructed the outside disappeared, revealing the appearance of a warehouse, a large rectangular building with a closed door.

"Open!"

Lin Feng looked at the huge and thick Xuantie Gate and slammed it out with a punch.

With a "boom", the Xuantie Gate was directly punched out of a huge hole, enough for one person to enter and exit.

Inside the warehouse. There was still a large amount of Xuantie stored, and Lin Feng also put all of it into the storage space.

"Well, the crimson one is the Xuantie Essence? I don't know if there is a Xuantie Mother. Lin Feng saw a small pile of crimson metal in the distance, and said with a smile on his face. The dark iron is A8 grade, then the dark iron essence is B8, and the rare dark iron mother is C8 grade! A large dark iron mine, the dark iron essence can have 1/10,000 is good. As for the mother of dark iron, it is very good to have one-ten-thousandth of the amount of dark iron. It can be seen that the proportion is exaggerated! Lin Feng also didn't have much hope for the Xuantie Mother, and it was not bad to get these Xuantie essences.

The volume is about 35 cubic meters, a total of about 1,200 tons. Lin Feng put away the pile of dark iron essence.

Soon, Lin Feng cleaned up all the dark iron in the entire warehouse.

"Keep looking, see if there are any dark iron essences in this steel city!"

Lin Feng continued to carry out a large-scale search!

The whole city is made of black iron, but many of the houses and houses are not black iron. It's just that it's been too long, and most of them have rotted.

Searching widely, Lin Feng also occasionally found some very small pieces of 'Xuantie Essence', which were obviously treasured by miners in some decaying residences. Each harvest is small, but the number of times it can't be sustained, and it adds up to thousands of tons!

Half an hour later!

"Boom!"

Lin Feng kicked on the basement door of the dirty, decaying mansion, and the dust on the door fell with a bang, revealing the color of the door itself—crimson.

"The door of the Xuantie Essence is made of Xuantie Essence, what is in this basement?" Lin Feng showed joy, "Collect!" Directly put a Xuantie Essence door weighing several tons into the space ring, and then Lin Feng stepped into this basement that no one had entered for hundreds of thousands of years.

The basement occupies a large area.

"Xuantie Mother!"

Lin Feng's face was overjoyed, a large number of decaying weapons were placed in a very orderly manner in the huge basement! The largest thing that took up the space was a large amount of crimson metal that was stacked tightly, and the volume was far greater than the one Lin Feng had collected in the warehouse! And in the center of the crimson metal, there was a piece of blood-red metal!

There are about 12,300 tons of dark iron essence, and about 360 kilograms of C8 grade dark iron mother. Compared with the last time, the dark iron essence collected in the warehouse is only a little more than 1,000 tons, and the dark iron mother is not at all. This harvest was obviously very satisfying to Lin Feng.

After searching again, Lin Feng soon found four other places where a large amount of dark iron was hidden, and the harvest was much larger than that of the warehouse.

Since then!

In the entire underground steel city, Lin Feng scavenged almost all the Xuantie Essence and Xuantie Mother.

Among them, the dark iron essence reached about 33,600 tons, and the dark iron mother was about 2.34 tons.

"So much Dark Iron, Dark Iron Essence and Dark Iron Mother, plus this steel city, I think it's almost enough. "Lin Feng flew and landed in the center of the steel city, which is a huge square.

"Whew!"

Lin Feng sat in the center of the square, his body was shrouded in a layer of silver light, the nine stars in the dantian shook together, and a brilliant silver flame flew out, only the size of a fist, it looked very inconspicuous, but it was nothing that was not burned, domineering and unparalleled, this flame was just suspended in front of him, and it made the surrounding void continue to melt.

As soon as Lin Feng's mind moved, this flame rose against the wind, turning into a sea of fire, and the ground of this city made of dark iron began to melt, turning into dark iron juice flowing.

The sea of fire continued to spread until the entire subterranean city was enveloped and burned, and even the earth above the city was burned into nothingness in the flames, and the subterranean city had been exposed to the Martian ground.

"Snort!"

Time passed, and it didn't take long for the entire underground city to be burned red, and with a bang, the whole city was completely melted. The flames were even more violent, burning, gradually quenching and extracting the impurities mixed in the dark iron, burning over and over again, and finally there was only a large mass of black black molten iron in front of Lin Feng, suspended in mid-air, in this molten iron, there were wisps of silver light flickering, magnificent, like a starry sky, very gorgeous and beautiful.

After refining this steel city, Lin Feng did not stop, took out the massive amount of dark iron, dark iron essence and dark iron mother that had been put away from the space ring, and continued to refine it, and it didn't take long for it to become three separate juices, a mass of ink, mixed with the previous mass of dark iron water, a mass of crimson, a mass of blood red, all suspended in front of Lin Feng.

After the material refining was completed, Lin Feng was finally about to start refining weapons, this step was very important, and there was no room for negligence, otherwise these materials would be refined. Lin Feng took a deep breath and completely concentrated his powerful spiritual power, at this moment, any slight change could not escape his control.

With a light drink, Lin Feng's hands instantly made a dazzling seal, flying out silver runes one after another, and then merged into the three balls of liquid juice, gradually exuding a mysterious aura.

As soon as his mind moved, the inky black iron juice was the first to change, and soon, it formed a peculiar weapon embryo body, prismatic shape, and the shape of a three-sided bar, which was a three-sided military thorn, but this three-sided military thorn was very large, suspended in the air, and the length was almost more than thirty kilometers long.

"Whoa!

The crimson Darkiron Essence Juice and the blood-red Darkiron Mother Juice also flew over one after another, the Darkiron Essence Juice covered the surface of the Triangular Army Thorn, and the inky Triangular Army Thorn immediately turned crimson, and the smallest amount of Darkiron Mother Juice dyed the blade blood-red.

"Boom!"

The huge triangular army was pierced with a flash of red light, and a terrifying sharp edge qi rose directly into the sky, Lin Feng controlled it in his mind, and slashed it out with a knife, and immediately split a huge crack on the Martian ground that spread for an unknown number of kilometers.

Lin Feng's hand pinched the magic trick, and the huge three-edged military thorn immediately became smaller in size, flying back in front of Lin Feng, the silver light on it was circulating, and it was extremely mysterious, especially on the blood-red blade, flashing with Dao Dao Sen cold brilliance, the sharp sword was uncertain, and it was terrifying.

"Well, it's not bad, with the addition of Xuantie Essence and Xuantie Mother, the power of this three-edged military thorn has really increased greatly, especially the blade tempered by Xuantie Mother, which is extremely sharp, enough to cut gold and broken stones, and is indestructible. Lin Feng took the Triangular Army Thorn into his dantian and fell into the star in the center, warming it with the stellar fire.
