Castle of Black Iron

"Principally yes?" Zhang Tie knew that it was not that easy given the tone of Heller.

"Yes. Castle Lord, you have to know some points!" Heller said calmly, "The daily output of the aura value couldn't match the basic energy that could be gained by the Abyss of Elements each day. If not include the aura value points that you have accumulated over the past years, the daily aura value increase that could be produced by plants in Castle of Black Iron could only form 0.16 square mile's land which could contain ores. Unless you expand the current land area of Castle of Black Iron by over 30 times, namely having it reach at least 7,000 square miles while being covered with a wood on its surface could the daily aura value increase match the daily basic energy increase and meet the constantly expansion of the space of Castle of Black Iron. The premise is that Castle Lord has to provide enough merit value points!"

"Besides, Castle Lord needs to know some more tips. First, the ores are produced optionally in the process of the formation of the earth's surface; 160 square miles' land is just the minimal requirement for the formation of ores, which are of the lowest qualities. They might even not be formed sometimes. Even though it is a gold ore, don't expect that you could gain hundreds of tons of gold from it. You could gain at most a few tons of gold from it in the earth on such a scale. The greater land area you could form for a time, the more varieties and amount of ores could you gain."

"Second, there are merely less than 10 templates about the varieties of ores that could be formed in Castle of Black Iron. The former two kinds are the low-quality iron ores and crystal ores that you gained in Wild Wolf Valley. The other ores originate from those crystal ores and ordinary ores that Castle Lord gained from the Earth-elements Realm casually. If Castle Lord wants more varieties of ores in Castle of Black Iron, you have to provide the corresponding templates. The higher level the ore is, the more aura value and merit value would it require. Additionally, as Castle of Black Iron form ores randomly, even if Castle Lord inputs a great amount of aura value and merit value in forming it, you could not gain high-level ores for sure. The more aura value and merit value you input in, the more possible it will be for you to gain high-quality ores. Additionally, the possibility has an upper limit..."

Whenever Heller "woke up" Zhang Tie, he would become very serious like a set of precise difference engine.

After hearing Heller's words, Zhang Tie indeed knew it much better. However, he didn't give up his thought completely.

"I've purchased plant seeds. But I've not imagined that I could gain a piece of God's Star this time. Therefore, the bottleneck of basic energy storage is solved at once. The insufficiency of aura value that you mentioned just now is indeed a problem; however, it doesn't mean that I couldn't solve it!" Zhang Tie said as he started his multi-tasking ability and gained a figure at once, "The basic energy storage that Castle of Black Iron absorb per month could be used to expand 160 square miles' land in the thickness of 50,000 m. As long as I maintain the current earth thickness of 200 m, I could expand 160,000 square miles' land per month. Is that right?"

"Yes!"

"Can't the current aura value and merit value in Castle of Black Iron meet such an expansion one month later?"

"Castle Lord, your merit value is enough for it; however, even one month later, the aura value in Castle of Black Iron could only meet the expansion of about 9,000 square miles' land!"

"Well, just 9,000 square miles' land!" Zhang Tie forcefully waved his hand as he determined his mind in a split second. He added, "Whatever, there're only a few people in Castle of Black Iron. They don't pose a great demand for ores. Let's make a thin pie first. After that, we will spread plant seeds over it. We only need to make the increase in daily aura value match the increase in daily basic energy as fast as possible and constantly meet the expansion of Castle of Black Iron. After solving this problem, I will further solve the provision of merit value!"

"Castle Lord, do you plan to expand and improve Castle of Black Iron as fast as possible in the future?"

"Yup. After this event in Xuanyuan Hill, I'm afraid that Taixia Country would be increasingly chaotic. I might have to live in here with my family members and those people that I could save. Therefore, I should make some preparation now!"

Zhang Tie then negotiated with Heller about the details of the expansion of Castle of Black Iron 1 month later beside the Abyss of Elements. After the negotiation, Zhang Tie suddenly thought about something as he asked Heller, "Oh, Han Yuanhong and Han Zhengfang should not only carry one piece of God's Star. I saw a tan token when Han Zhengfang died..."

"They indeed carried many more items. Castle Lord makes unimaginable achievement this time. Those items are in the treasure bank of the palace tree. Castle Lord, you should review them by yourself. You might have a surprise!" Heller said with a meaningful look.

'The last surprise that Heller mentioned referred to the piece of God's Star, what about this one?'

Zhang Tie's curiosity was aroused by Heller at once. He patted the thunder hawk to have it fly off before saying, "If you say so, I have to count my booties!"

"I think Castle Lord will not be disappointed!" Heller replied with a smile.

After throwing another glance at the Abyss of Elements in front of him, Zhang Tie left...

...

A few minutes later, Heller and Zhang Tie returned to the lobby of the palace tree. Zhang Tie looked around the small tree before entering it.

This fruit of brilliance almost became dark as if it could absorb the surrounding light. In the dark, the fruit contained a bizarre spiral light band which looked like a galaxy in the universe. Zhang Tie had not seen such a fruit of brilliance; however, he could sense the terrifying spiritual energy in this fruit of brilliance, which was far greater than that of any fruit of brilliance that he had ever taken.

There were 3 fruits of judgment on the side of this fruit of brilliance.

Zhang Tie knew that these fruits of judgment were of the same skill——body-separation skill. At the sight of the three fruits of judgment, Zhang Tie had known that his body-separation skill would advance to a super level from preliminary level. After taking the 3 fruits, the final fruit of judgment would advance his body-separation skill to master-level.

A red and black fruit of bloodline was hiding in the dense leaves of the small tree in the shape of a bizarre 16-side crystal gem. He could almost not discover it if he didn't look at it carefully. Like that pitch-dark fruit of brilliance, this fruit of bloodline also manifested something special. This one was larger than the former ones; colorful lights were flashing by inside the fruit of bloodline now and then.

'When I killed Old Monster Qi, I've already gained a fruit of bloodline, which contained 1784 points of bloodline energy. I spent 67 points in activating a fundamental "spear affinity". There are still 1717 points of bloodline energy left. This fruit of bloodline definitely carries much more bloodline energy points than the former one. I could gain 1784 points of bloodline energy by killing an earth knight when I was a black iron knight. This time, after killing a shadow knight as an earth knight, I should at least gain two more times bloodline energy than the last time.

Besides these fruits, there were two more fruits of redemption on the small tree.

Watching those bizarre fruits, Zhang Tie knew that he had made a fortune. After taking these fruits, his overall strength would definitely rise greatly once again, as the fruit of brilliance, the fruit of bloodline and the 3 fruits of judgment were all of the unusual effects.

'Besides these fruits, I've not fully converted the water elements that I gained from Han Zhengfang and Han Yuanhong into my own chakra.'

Zhang Tie revealed a brilliant smile. He was not anxious about taking them right now; instead, after circling around the small tree and counting those fruits, he left the small tree and followed Heller into the treasure bank of the palace tree.

Zhang Tie's treasure bank was at the bottom of the palace tree. The entire treasure bank covered about 60,000 square meters and was higher than 50 m. There was a golden fluorite crystal lamp in each a few meters, which illuminated the entire treasure bank. The entire treasure bank was divided into 4 regions. Each region was filled with various rarities that Zhang Tie plundered from subcontinents and continents. If a commoner entered the treasure bank for the first time, he might be thrilled too much and have a heart attack at the sight of so many treasures. It was like the legendary paradise where was covered with treasures.

Precious metals such as gold and silver were the most ordinary items in the treasure bank. Zhang Tie didn't pack gold in crates, but in piles like the piles of wheat straws on the threshing grounds in rural areas. Each pile of gold was about 4-5 m high like a golden Mongolian yurt. The moment one entered the treasure bank, he would see dozens of rows of tidy golden Mongolian yurts extending all the way towards far...
