"In principle, so?" Zhang Tie knew that if Heller said this, then the specific operation might not be as optimistic and simple as he thought.

"That's right, there are a few questions that the castle lord needs to be clear!" Heller said calmly, "The daily output of the aura value of the Black Iron Castle cannot match the basic energy obtained by the elemental abyss, if you don't take into account the aura value accumulated in the Black Iron Castle in the past few years, the daily new aura value of all the plants in the Black Iron Castle is probably only enough to generate 1 square kilometer of land that can be derived from mineral deposits, unless the existing land area of the Black Iron Castle is expanded by more than thirty times, that is, at least 120,000 square kilometers, There must be a forest on top of this 120,000 square kilometers of land, so that the daily increase in the aura value of the Black Iron Castle can match the current daily increase in the basic energy reserves, and it can support the continuous growth of the Black Iron Castle. ”

"The castle lord also needs to know a few points, first, the mineral deposits provided by the black iron castle are randomly generated in the surface generation process, and 1000 square kilometers of land is only the minimum area requirement for the black iron castle to generate mineral deposits, and the scale of the mineral reserves generated by it is only the lowest level, and it may not even be generated at some time, the mineral deposits generated at this land level, even if it is a gold mine, the castle lord should not expect that gold mine to produce hundreds of tons of gold, this is simply impossible, even if gold is really generatedThe gold reserves in a gold mine of this scale are estimated to be only a few tons. Only the larger the area of land generated at one time, the greater the type and size of mineral deposits and veins contained in the land. ”

"Second, there are currently less than ten templates for the types of minerals that can be generated in the Black Iron Fortress. The quantity is relatively small, and the first two are from some low-grade iron ore and crystal ore obtained by the castle lord during the trial in the Wild Wolf Valley. Some of the latter mineral deposits are derived from several crystal ores and ordinary minerals that the castle lord obtained casually in the Earth Metaverse, and he wants the Black Iron Castle to generate more kinds of mineral deposits. The lord of the castle must provide the corresponding mineral template for the castle of black iron, the higher the level of minerals, the more aura value and merit value are required when generating, and because of the randomness of the veins generated by the castle of black iron, sometimes even if the lord of the castle invests a large amount of aura and merit value into it, the level of the newly generated vein deposits is difficult to guarantee that it must be high, and more aura and merit value are put into it, but it will correspondingly increase the probability of the castle lord getting high-quality mineral deposits and veins in the new land, And there's an upper limit to that odds......"

Every time it comes. Heller will become meticulous, like an accurate differential machine, making Zhang Tie "sober and sober".

When Heller said this, Zhang Tie was indeed much sober, but he did not completely give up his thoughts.

"I have already ordered the seeds of the plant, but I didn't expect to harvest a God Star this time, and solve the bottleneck of the basic energy of the Black Iron Castle at once, the problem of insufficient aura value you just mentioned is indeed a problem. But it's not unsolvable! Zhang Tie said as he spoke, the ability of the bead in his mind moved, and he suddenly got a number, "The basic energy reserves that the Black Iron Fort now absorbs every month can expand the Black Iron Fort by 900 square kilometers to reach the thickness of the earth's crust. If I only need the newly generated land to maintain its current thickness, which is 200 meters, then it will only take a month. That is, in thirty days, the basic energy reserve of the Black Iron Fortress can allow me to generate 225,000 square kilometers of land. Is that so? ”

"That's right!"

"Is the current aura value and merit value of the Black Iron Castle enough for the Black Iron Castle to complete such an expansion in the next month?"

"The merit of Lord Castle is enough, but even in a month. The aura value of the Black Iron Castle is only enough to complete an expansion of 150,000 square kilometers! ”

"150,000 square kilometers is 150,000 square kilometers!" Zhang Tie waved his hand vigorously, and instantly made up his mind, "Anyway, there are not many people in the Black Iron Castle now, and there is not much demand for mineral deposits, let's spread out a large cake first, and then sprinkle the seeds of plants and trees, as long as we can make the daily aura value generated by the Black Iron Castle in the shortest possible time match the basic energy reserves that the Black Iron Castle increases every day, and can continue to support the expansion of the Black Iron Castle, we have succeeded, solved this problem, and there is only one merit value left, I'll take my time and figure it out! ”

"The Castle Master plans to rapidly expand and improve the Black Iron Castle in the future?"

"With this idea, after this incident in Xuanyuan Hill, I estimate that Taixia will become more and more chaotic in the future, maybe when, I will bring my family and people who can be rescued in, now make a little more preparations, there is no bad thing!"

Now that he has said this, Zhang Tie carefully discussed some details of the expansion of the Black Iron Castle with Heller next to the Elemental Abyss a month later, and after the discussion, Zhang Tie suddenly remembered something and asked Hailer, "By the way, Han Yuanhong and Han Zhengfang should have more than this God Star, I remember that when Han Zhengfang hung up, there was also a bronze token on his body that fell off......"

"There is indeed more than one God Star on the two of them, the Castle Lord's harvest this time is very large, they have exceeded my expectations, those things are now in the treasure vault of the palace tree, the Castle Lord had better go and see for himself, maybe there will be surprises!" Heller said meaningfully.

The last time Heller said surprise, it was because of this God star, I don't know what the surprise Heller said this time was?

Zhang Tie's curiosity was immediately hooked by Heller's words, and he patted the Thunder Falcon and made the Thunder Falcon fly, "You say so, I really have to go back and count the harvest this time!" ”

"The castle lord will not be disappointed!" Heller laughed too.

Glancing at the elemental abyss in front of him again, Zhang Tie left......

……

A few minutes later, Heller and Zhang Tie returned to the hall of the palace tree again, and when they came to the hall, Zhang Tie stopped first, and did not rush to the treasure house, but first circled around the small tree and looked at the small tree carefully.

The color of the fruit of brilliance on the small tree became more deep, almost dark, as if it could suck in the surrounding light, and in that piece of darkness, it was like a starry sky, and the fruit was dotted with stars, condensing into a strange rotating spiral band of light, like a galaxy in the universe, flashing with an unpredictable luster, such a fruit of brilliance, Zhang Tie had never seen it, but Zhang Tie could feel the spiritual power contained in this fruit of brilliance, absolutely terrifying, Far more than any glorious fruit I've ever eaten before.

Next to this Fruit of Radiance, there are three Fruits of Judgment.

Now the fruit of judgment, Zhang Tie only has the last skill left - mirror doppelganger technique, as soon as he looks at these three judgment fruits, Zhang Tie knows that these three judgment fruits can definitely improve his mirror doppelganger technique from the primary level to the super realm, after these three judgment fruits, the fruit of judgment that this little tree can bear is only the last master-level mirror clone technique.

Red and black, like a strange sixteen-sided gem crystal, the bloodline fruit is hidden behind the bushes of the small tree, it is absolutely difficult to find if you don't look closely, and the color has become dark and dark like the glorious fruit, this time the bloodline fruit, also showed some special things, in addition to the size of the fruit is a whole circle larger than before, the entire bloodline fruit, there is actually a rainbow-like brilliance flashing from time to time.

The last time I killed Qi Lao Monster, I got a bloodline fruit, and that bloodline fruit brought 1784 points of bloodline energy, these bloodline energy, I used 67 points, activated a basic "gun affinity", and the others completely left 1717 points of bloodline energy did not use, the bloodline energy points brought by the bloodline fruit obtained this time will definitely be much more than the previous one, and I can have 1784 points of bloodline fruit when I kill Qi Laowei, an earth knight, this time I killed Han Zhengfang, At least more than double the last time to be reasonable.

In addition to these fruits, the little tree bears two more fruits of salvation.

Looking at those strange fruits, Zhang Tie knew that this time he would definitely make a lot of money again, and if he ate these fruits, his strength would definitely increase again, whether it was the fruit of brilliance or the fruit of bloodline, or the fruit of judgment, it was extraordinary.

In addition to these fruits, until now, the water element he absorbed from the Han family's father and son has not been completely refined and condensed into his own chakra.

A bright smile appeared on Zhang Tie's face, and he was not in a hurry to eat now, but after going around the small tree and counting the fruits on the small tree, he left the small tree and followed Heller to the treasure house happily.

Zhang Tie's treasure vault is in the lower layer of the palace tree, the entire treasure vault is almost more than 100,000 square meters in size, more than 50 meters high, the golden fluorite crystal lamp has a lamp every few meters, the entire treasure pavilion is bright, dazzling biochemical, the entire treasure pavilion is divided into four areas, each area, is full of Zhang Tie from various subcontinents and various places to harvest all kinds of precious treasures, if it is an ordinary person to Zhang Tie's treasure pavilion for the first time, I am afraid that just entered, see the things inside will be excited heart shock, I thought I had come to heaven full of legendary treasures.

Gold and silver are the most common things in the treasure pavilion, the gold in the treasure pavilion of Zhang Tie, but not in the box, but like the wheat straw piled up on the threshing floor in the countryside, piles of high piles, each pile, are piled up four or five meters high, like a golden yurt, the first thing anyone sees when entering the treasure pavilion is dozens of neat rows of yurts from the entrance to the distance......
