Compared with others, Li Li was a little more careful after seeing this optimus iron pillar, this large iron pillar with a length of about 8,500 meters and a diameter of about 3 meters was obviously planted after the disaster. ⊙ top novel,

If you want to plant this Optimus Iron Pillar, even before the disaster, it is very difficult to rely on all kinds of heavy equipment, let alone after the disaster, and it is in a remote place like the northwest where there is no industrial base, so this Optimus Pillar is not planted by large machinery and equipment, but artificial.

Through Zhang Yao's news, Li Li knew that the city lord of the Steel City was a ninth-order peak ability, and his ability was to control metal, so this Optimus Iron Pillar was planted by this person with his strong ability, which shows that this person's strength is so strong that it surpasses ordinary ninth-order ability.

"Damn, is there too much steel in this steel city, it's okay to eat enough, plant such a huge pillar." Tang Long looked at the Optimus Iron Pillar in the distance, his expression was unhappy, this giant pillar didn't seem to have any effect, not even a lookout defense function, because this Optimus Giant Pillar didn't have a ladder to go up, in other words, it was an ornament.

"It's a show of strength!" Li Li looked at the Optimus Giant Pillar that was reaching into the sky, his eyes narrowed slightly, thoughtfully.

"Show off?" Tang Long also fell into thought, he was originally a smart person, and after Li Li's reminder, he reacted immediately.

Indeed, this is a show of strength, being able to stand up such a huge Optimus Giant Pillar is very revealing in itself, ordinary ninth-order supernatural abilities can't do it at all, even ninth-order peak power-type superpowers can't do it, if this Optimus Iron Pillar falls, even a small mountain will be smashed flat.

Hearing the conversation between the two, everyone gasped, and a trace of shock appeared on their faces, indeed, what kind of terrifying existence the person who can stand up this Optimus Iron Pillar is, I dare not imagine.

"You don't have to worry, the City of Steel has strict rules, as long as we don't commit crimes, there will be no danger." Zhang Yao was not as surprised as everyone else, he had been to the City of Steel many times, and he was immune to the Optimus Pillar, and in addition, for him as a fourth-order ability, there was not much difference between the seventh-order ability and the ninth-order peak ability, because they could easily kill him in seconds, so he could only experience the strength of the city lord when he saw the Optimus Pillar, but he didn't know how strong it was.

"Alright, let's go!" After a while, Li Li withdrew his eyes from afar and said lightly.

Everyone glanced at each other, stopped talking, and followed Li Li towards the steel city slowly, an invisible depression spread, in addition to Li Yunpan in Li Li's party, the lowest Mina also became a fifth-order ability under Li Li's forcible training, so he had a deep feeling for the strength of the maker of the Optimus Giant Pillar, especially Tang Long, who had reached the peak of the seventh order, and the feeling was particularly obvious.

Ten minutes later, the group came to the gate of the steel city, and looked at the steel dragon-like city wall, the first feeling of the steel city wall is majestic, solid and unbreakable.

The steel city wall is about 20 meters high, it looks pitch black, all of it is made of molten iron, not made of countless steel welds, this steel city wall that stretches for more than ten kilometers is almost a whole, it is difficult to break, which is also one of the reasons why the steel city has been attacked by countless monsters but is unharmed.

"It's ,,, too, so much steel from there!" Even a high-level powerhouse like Tang Long, who had seen the world, was shocked by the majesty of the steel city in front of him, and he looked at it to see that steel was still steel.

"Brother Tang Long, the Iron City has collected almost all the iron products in a radius of thousands of miles here, and there is also a large iron ore smelter nearby." Zhang Yao looked at the familiar city wall in front of him, and he was also full of emotion, he was one of the witnesses to the establishment and rise of the steel city.

"Let's go inside!" Li Li looked at the steel city gate not far away, his face was flat, and people didn't know what he was thinking.

The gates of the Iron City are very wide and majestic, and the buildings are somewhat modeled after the gates of ancient imperial palaces, which are made of two giant iron plates that are palm-wide, and these two swarthy iron plates give people a sense of thickness and solidity.

Passing through the gate of the antique building, a prosperous town appeared in front of everyone, the steel city was formerly a county-level city, and what is even more difficult is that this county-level city has not been affected by the war, and it is still exactly the same as before the disaster.

Although this county town is a small economically backward county town in the west, it is also quite prosperous in the wilderness, after all, it is a small city in good condition, and the facilities before the disaster are completely preserved.

The population in the town is quite large, about 100,000 people, in this small county is relatively crowded, the main buildings in the town are almost all government office land, among which the luxurious county government building, as well as the fire brigade, various public institution buildings have been occupied by the rulers of the steel city, re-set up various functional departments, play a management role.

In addition to the government office building, the whole town can be regarded as a luxury building is a three-star hotel before the disaster, of course, this three-star hotel actually does not meet the three-star requirements, and can not be compared with the three-star hotel in the coastal area, but there are also eight floors, which is a relatively luxurious building, and the rest of the buildings are only six floors at the highest.

The City of Steel is open to survivors without any restrictions on their access, which attracts a lot of survivors to this place, and it becomes a market for the exchange and distribution of goods.

Fighting is strictly forbidden in the Steel City, and the city is relatively safe, which is one of the reasons why most people are willing to trade here, but the biggest trade in the Steel City is the slave trade.

The whole town overlooks like an irregular baked cake, the town has only two main streets, showing a cross-shaped cross, north-south, east-west through the whole town, the center is the intersection of the two main streets, countless small streets and alleys are all over it.

After Li Li and his party entered the city, they walked on a main road, the main road is very wide compared to other small alleys, it should be a standard six-lane before the disaster, but there are no cars on the street, but unexpectedly there are some locomotives similar to locomotives, these locomotives are relatively large, and the size of the five-bridge car, but these locomotives are not carrying pedestrians, but transportation.

"What kind of car is this? Why is it still smoking? Han Luojia looked at a whizzing locomotive with a stunned expression, looking inexplicable, because this locomotive not only made a clattering sound like a train when it was running, but also had a chimney on the roof of the car, and white gas was constantly rising from it, a bit like a coal-burning train locomotive before.

"This is a locomotive that specializes in transporting molten iron, and it burns coal, which is equivalent to a steam locomotive." Zhang Yao looked at the locomotives that disappeared at the end of the street and explained that there was a huge iron ore factory near the Iron City, and the molten iron burned from the iron ore was transported by these locomotives.

"Transporting molten iron?" Mina's face changed slightly when she heard the molten iron, she is a fifth-order fire attribute ability, with her current strength, she can release a flame of 600 degrees Celsius at most, and the melting point of iron is more than 1500 degrees Celsius, what kind of concept is that, if you throw a person into the molten iron, at most five seconds, it will turn into ashes, for a fire attribute ability, she understands the temperature more than others.

"Just kidding! How is it possible to transport molten iron in a locomotive, so that the locomotive will all melt, and I don't feel the temperature of the molten iron? Zhu Hu sneered, obviously not believing Zhang Yao's words, and felt that Zhang Yao's exaggeration.

"This is indeed a locomotive for transporting molten iron!" Li Li glanced at everyone, he was a top powerhouse at the peak of the ninth order, his perception ability was far beyond that of others, when the locomotive roared past just now, he could feel that the locomotive had an extremely high temperature inside.

"What?" Mina looked at Li Li with a look of disbelief, it was too unbelievable to transport the molten iron by car, even if a piece of steel was thrown into the molten iron, the steel would melt at a speed visible to the naked eye.

"This is the most primitive iron-making method, in a large iron pot, use fire bricks and cement to build a layer of protective insulation film, and then pour the molten iron into it, with this layer of insulation film, the molten iron can be safely installed in the large iron pot." Zhuhu looked at the people with a confused face, took a step forward, and explained freely, it has always been others who have solved his doubts, and this time it was finally his turn to popularize science for these people, and there was a feeling of raising his eyebrows in his heart, especially when he looked at Han Luojia, his eyes became natural.

"What fire bricks? What cement? What is a heat insulation film? Han Luojia raised her eyebrows, and looked at Zhuhu very unhappily, as if she didn't know what Zhuhu knew, and she was very depressed.

For this most primitive iron smelting method, Han Luojia naturally does not know that this iron smelting method has long been eliminated, and only in some remote places in the west can this high energy consumption and high pollution iron smelting method be seen.

After graduating from the third grade of Zhuhu Primary School, they worked everywhere, including an iron worker in an iron factory in their hometown, so they know more about these.

"Alright, let's go!" Li Li interrupted the argument between the two with a slight wave of his hand, now the top priority was to find a place to settle in the town, he didn't want to waste time on meaningless arguments.

For the information of the steel fortress, Li Li did not ask Zhang Yao a little, there is not only an iron ore factory near the steel fortress, but also a coal mine, so that the huge city wall can be poured by burning coal and smelting iron, otherwise it is impossible to build such a magnificent steel city just by melting those iron products, you must know that this optimus iron pillar alone will probably require tens of thousands of tons of steel.
