In that rotating three-dimensional image, the entire Black Iron Fort has changed its appearance. The land is ten times larger than it is now, and there is an ocean that has never been seen before. Just looking at it casually will make people Feeling blood boiling.

This is my space. This is the land that I have accumulated bit by bit. Zhang Tie said to himself, an indescribable sense of pride surged in his heart. Apart from the appearance of land and sea, black The sacred mountain in the Iron Fort, where Zhang Tie is now, suddenly rose to tens of thousands of meters, even more majestic and majestic, with some mysterious and ethereal atmosphere.

Zhang Tie saw that there were a few more white clouds in the sky in the three-dimensional map.

"Ah, there is a cloud, what is going on?" Zhang Tie asked Heller.

"With the expansion of the space of the Black Iron Fort, the natural circulation system of this space will gradually emerge. This cloud is only the beginning. If this space can continue to expand in the future, there will be more complex and three-dimensional climate types. Appeared to adapt to the survival of various creatures."

"Will it rain on this cloud?"

"May or not!" Heller replied vaguely.

"Huh? What does that mean?"

"I mean in this space, if you want it to rain, it will rain, and if you don't want it, it won't. All of this is controlled by Lord Fortress!"

Zhang Tie nodded, expressing that he understood that it is indeed magical to control the weather, but if it is placed in the Black Iron Fort, it would be commonplace, and Zhang Tie was not surprised.

"How many people can this newly expanded land support?"

"The newly formed land is very fertile. The main food crops can grow three seasons a year. If this land is fully utilized, it can feed more than 3 million people!"

"A population of more than 3 million?" Zhang Tie frowned slightly and thought about it, then stretched out his hand to operate in the three-dimensional map, "The area of ​​the ocean is too large, cancel it first, all become land, let the land area as much as possible At the same time, in this land, there will be several inland freshwater lakes, as well as as many natural river systems as possible, which can irrigate the land on both sides of the land, so as to maximize human settlements and accommodate more people. Survival here is a prerequisite!"

Under Zhang Tie's manipulation, the ocean disappeared, the land area expanded by a quarter, and several lakes and rivers appeared in the land.

Heller saw Zhang Tie's changes and instantly understood what Zhang Tie meant. "Fort Lord, is this preparing for more people to enter the Black Iron Fort in the future?"

Zhang Tie nodded. This jihad has only just begun a few years ago, and it has already displaced countless people. In the future, this jihad will be even more cruel. Zhang Tie doesn’t know what the final outcome of this jihad will be. Under the circumstances, he wanted to make more preparations for the future as much as possible. Here, it can become a sacred refuge, so that more people have the opportunity to survive. Let’s talk about the ice and snow wasteland, as a lonely overseas enclave in the Blackson Human Race Corridor. If the entire Blackson Human Race Corridor falls, Zhang Tie doesn’t know how long the ice and snow wasteland can last. If one day the Ice Wasteland If you are forced into a desperate situation, then, as long as you are there, as long as you have this Black Iron Fortress, you can move all those who follow you in the Ice and Snow Wasteland to the Black Iron Fortress and run away. This method seems a bit irresponsible and lazy, but Zhang Tie knows that in jihad, letting people live is the most important thing.

After understanding Zhang Tie’s thoughts, Heller thought for a while, and then started to move his hands. After a while, the entire three-dimensional map was adjusted to the same level, and then Heller pulled his hand, and the ground area of ​​the entire land suddenly resembled Like spreading the pie, it has once again expanded to more than 4000 square kilometers.

"Since the Lord of the Castle wants to accommodate as many people as possible, the newly generated land in the Black Iron Fort does not need to be so heavy. According to the previous plan, the thickness of the land and the rock layer of the Black Iron Fort is 800 meters, after the adjustment, the thickness of the land and rock layer of the Black Iron Fort will become 200 meters, the land area can be increased a lot, and the entire Black Iron Fort can accommodate and feed a population of more than 10 million."

Zhang Tie patted his forehead vigorously, how could he have forgotten this.

"Is there no effect?"

"There is no effect. These people basically live on the surface. If you only consider survival, the surface depth of 200 meters is enough. If the lord of the castle is still not satisfied, the thickness of 20 meters is fine. Anyway, everything here. They are all carried in this space. As long as there is such a layer of soil on the ground, plants and food can grow!"

20 meters thick? Zhang Tie rubbed his face, and it really became rolling on the panel. Although the thickness would not have any effect on the Black Iron Fort, it always felt weird-a guy holding a hoe. Can the sky dig the earth to cross it? This is also a little thinner. It’s better to stay a little more practical where people live. Forget it, the new land area is only 200 meters thick, so that people can survive, but also thick and solid. If you need it in the future, you will be yourself. Just think of a way to thicken it. Anyway, there is no such urgent need here.

By the way, there is one more question.

"Can the Dark Iron Castle give birth to veins this time?" Zhang Tie asked Heller hopefully.

"Black Iron Fort has the ability to generate mineral veins. It is a high-level ability. At this stage, the price it needs to pay is too great. Generating a small low-level mineral vein at will requires a massive amount of merit and aura. Value, there are some other prerequisites, so I don’t recommend Lord Castle to use this ability now."

Zhang Tie thought for a while, and asked Heller a question, "Then with the current merit value, aura value and basic energy reserve level of the Black Iron Fortress, if you want to invest all of them to generate a vein, what will that vein be? What kind of level?"

"If all the current resources of the Black Iron Fort are invested at once, due to the influence of the barrel effect, after all the merits are exhausted, the Lord Lord can obtain a pocket-sized one in the Black Iron Fort. Low-grade ordinary iron ore with a total ore reserve of less than 80,000 tons. The mineral template of this iron ore comes from the fortress master who added the basic energy reserve to the fortress of the black iron during the trial in the wild wolf valley. Those low-grade discarded iron ore in the fort! At the same time, after the completion of the iron ore generation, because the merit value is exhausted, most of the spiritual energy is consumed. Although there is a large amount of basic energy reserves remaining, the Dark Iron Fortress will not be able to Complete this space and terrain transformation again."

Heller's words suddenly made Zhang Tie sober, and Zhang Tie took a breath of air. He didn't expect that it would be so difficult for the Black Iron Fortress to naturally generate veins, and the cost would be so high, but think about it carefully, Zhang Iron understands it. If it is so easy to make the Dark Iron Fortress generate veins, then let the Dark Iron Fortress generate some high-grade gold mines, gemstone mines or crystal mines at will, then you can not easily make it rich. Enemy country?

"In that case, I want to generate some mineral veins in the Black Iron Fort. It is impossible? Besides this method, is there any other method?"

"There are two ways to source the veins of the Dark Iron Fort. The first method just mentioned is that the Lord of the Fort provides the corresponding resources. After the conditions are met, the Dark Iron Fortress is designated to generate a certain kind of vein. The second method is The veins generated randomly after the expansion of the space and terrain of the Black Iron Fort, if the ocean or land area generated by the Black Iron Fort at one time exceeds 1,000 square kilometers, and the thickness of the surface exceeds 50 kilometers, that is, 50,000 meters, it forms a primary Crust, then, in this kind of space and topographical transformation, Lord Fortress will likely obtain one or more mineral veins or mineral deposits naturally generated in this space. The location, variety, and reserves of that vein are all random... "

"That is to say, if I have the ability to complete such an expansion, it is possible to obtain one or more random mineral resources by luck. Everything depends on luck?" Zhang Tie's eyes widened, and he did not expect the Black Iron Fortress. There is such an ability.

"That is both luck and chance. Generally speaking, the greater the one-time expansion and the deeper the surface and crust, the more types and reserves of minerals randomly generated in the Dark Iron Fort. This process, and The mineral generation process in the outside world is similar. If the fortress master can complete an expansion of the size of the Blackson Human Corridor at one time, then I can guarantee that the mineral deposits and mines in the newly expanded land of the Black Iron Fort The mineral veins will not be less than those in the Blackson Human Race Corridor."

Zhang Tie rolled his eyes helplessly. To make the Black Iron Fort complete that kind of expansion, with his current small body and small energy, even if he had been in the ocean for a hundred years, he would not have enough basic energy reserves. , Let alone have the corresponding merit value and spiritual energy value. Forget it, now it's too extravagant to play mineral veins in the Black Iron Fort. I really need to have that time. I might as well buy directly smelted metal outside.

After revealing this, Zhang Tie and Heller continued to adjust the three-dimensional map.

But thinking of his own practice during this period, Zhang Tie suddenly came up with an idea. He pointed to a place on the sacred mountain, "I need to build a training ground here, and the ground should be firmer?"

"Cultivation field?" Heller looked at Zhang Tie with some doubts.

"Just like the place where I practiced a few days ago, when I was cultivating, I could bring in the sea water from outside and wash it down at high speed. I think the effect of cultivating in that state is particularly good, and I can kill two birds with one stone while practicing. There are iron fetuses to eat!"

"No problem, Lord Castle plans to retreat in the sea in the future?"

"I have this plan!"

"In this way, it is better to create a waterfall on this side of the sacred mountain. The impact of the 10,000-meter-high waterfall is also very impressive. This allows the Lord Lord to have a better practice environment when he usually does not have the opportunity to retreat in the sea... "Heller said, swiping his hand on the three-dimensional map, a waterfall flew down from the side of the sacred mountain, and then splashed on the ground, and a river appeared...
