Castle of Black Iron

It had been one month since Zhang Tie entered Castle of Black Iron on July 15.

During the past one month, too many things had happened. Through observing shrimps, Zhang Tie got the essence of Immortal Fist Skill. As a result, his battle strength recovered.

During those days when he comprehended Immortal Fist Skill, Zhang Tie didn't continue to quench his body. Therefore, it had been only 9 King Kong Fruits on the small tree since August 6.

Besides King Kong Fruits, there were also a lot of fruits of redemption from the gratitude of gulf shrimps, hairy shells and earthworms.

However, among those fruits, the most eye-catching one was the new one——the fruit of redemption from the gratitude of spike shrimps.

When he imagined about the terrifying explosive force of spike shrimps, Zhang Tie came to the small tree with excitement as he touched the new fruit.

——Fruit of redemption——the explosive force of spike shrimps; not ripe yet.

——After this fruit became ripe, if Castle Lord takes it, the explosive force of the 700-odd pieces of muscles and over 300 million muscle fibers of your body would increase by two times.

——The explosive force of mutated spike shrimps could reach 240 times that of the total physical strength of their bodies. Therefore, the maximal number of the fruit of redemption from the gratitude of spike shrimps was 240. Each fruit will activate 1/240 of the gene segment of your body which was as same as the gene segment of golden uangs which represented strength.

——The current number of this fruit——0/240.

——The current total explosive force of Castle Lord is 6 times that of your total explosive force. After taking 240 fruits of redemption from the gratitude of spike shrimps, Castle Lord's total explosive force will reach 246 times that of your physical strength. Castle Lord will promote to a body with complete immortal strength.

Watching this raw fruit, Zhang Tie finally burst into laughter. As a result, the entire lobby of the palace tree was filled with Zhang Tie's laughter.

The fruit of redemption from the gratitude of spike shrimps could increase Zhang Tie's explosive force by 240 times. Zhang Tie's current explosive force was 6 times that of his physical strength. That was to say, when Zhang Tie took 6 fruits of redemption from the gratitude of spike shrimps, his explosive force would increase by two times on the basis of the current data. As long as he took 240 fruits of redemption from the gratitude of spike shrimps, his explosive force would increase by 40 times on the basis of the current data.

What did that mean?

Even spike shrimps could scramble for brilliance with the sun by punching out in the ocean. As long as Zhang Tie's explosive force broke through 240 times that of his physical strength, he would be able to output 40 times that of the current physical strength, which meant a new height.

If a person's physical strength was too small, even if he had hundreds of times greater explosive force, his battle strength would also be limited. Take spike shrimps as an instance, even though they had the most terrifying explosive force in the world, because of the small cardinal number of their physical strength, they didn't pose threat to most of living beings in the ocean; instead, they were usually caught and became people's food.

However, Zhang Tie was different than spike shrimps. At this moment, Zhang Tie's physical strength was already terrifying. Actually, none of the human and demon powers that Zhang Tie recognized could match Zhang Tie in physical strength.

Besides the great power granted by Infinite King Roc Sutra in the level of heavenly knight, he also had the strength of 1,800 golden uangs and the fruit of source. With these strengths, Zhang Tie was already unrivaled; however, due to his body with 1/2 immortal strength, his physical strength had increased by 2 more times. Besides, after activating his Kua'e Bloodline when fighting Versatile Demon Emperor, Zhang Tie's physical strength increased by 120% again...

All the above data were just the most conservative estimates. Because the body with 1/2 immortal strength could also enable Zhang Tie's physical strength to increase without limit. Additionally, Zhang Tie's basic strength would increase with his growth and exercise, not to mention that when he acquired the body with complete immortal strength.

Zhang Tie dared not imagine about the situation when his explosive force reached 240 times that of his physical strength...

Zhang Tie suddenly realized that he had already started the road where the greatest strength was proved to be the truth. Spear strikes, kinetic strikes and Immortal Fist Skill were all the extension and usage of the most basic and purest strength...

When Zhang Tie recalled it, he found that this road of cultivation had been fixed since he opened the book Iron Blood Immortal Fist as if everything was predestined...

As for how to reach further on this road in the future, Zhang Tie had to consider and plan it seriously now.

Raising his head, Zhang Tie watched the raw fruit of redemption from the gratitude of spike shrimps as his mind had long flown far away...

After quite a while, Zhang Tie became composed as he revealed a smile and picked a fruit of redemption from the gratitude of earthworms. Then, he sat under the small tree with crossed legs and started to take the fruit...

...

The vial of soul-washing pills that Bian Heng gave Zhang Tie contained 35 pills in total. According to Bian Heng, Zhang Tie could eat one soul-washing pill per day based on his great physique. 35 days later, even immortal emperors could barely notice that there was any problem with Zhang Tie's surging points.

Many people might still be wandering with that "compass" near Emperor NvWa City. Versatile Demon Emperor should be near there too. Therefore, Zhang Tie determined to eat all the soul-washing pills so that Versatile Demon Emperor could never discover his whereabouts anymore. Then, he would leave Castle of Black Iron for Mountain Ruins.

That was to say, Zhang Tie had to stay in Castle of Black Iron for over 1 month.

...

As he had enough time to eat fruits, Zhang Tie was a bit relaxed.

After taking one soul-washing pill and covering one surging point, Zhang Tie would take one or two fruits leisurely; then, he would quench his body for a few hours.

Despite being relaxed, Zhang Tie's overall strength was surging; especially whenever he took a King Kong Fruit, he would feel gaining greater defensive strength. Previously, his defensive strength was already amazing. But now, his defensive strength had been developing towards a terrifying level.

Previously, Zhang Tie was worried about becoming an intimidating monster if he took too many such fruits. Therefore, he always cared about any change in his body whenever he took a King Kong Fruit.

Someone might not care so much in order to be more powerful; however, if the price of being powerful was to be a monster in the eyes of his family members, Zhang Tie preferred to not be powerful. Zhang Tie once gave up the powerful demon body for recovering his human body; but now, if King Kong Fruit brought him any bad side effects, Zhang Tie would also abandon it decisively.

However, the fact proved that King Kong Fruits didn't bring Zhang Tie any bad side effects at all; unimaginably, after taking those King Kong Fruits, Zhang Tie found that his skin became whiter and shinier; his eyes became brighter; his bones became more agile and firm; his muscles and blood vessels became more flexible. King Kong Fruits' side effect was that it could make him more handsome. Therefore, Zhang Tie became completely reassured.

...

After staying in Castle of Black Iron for 8 days, Zhang Tie fetched Edward and gave a draft that he drew these days to Edward.

"Castle Lord, this is..." Edward asked Zhang Tie with amazement after taking a look at the draft.

"They are used for exercise. Just make it and apply some consolidating runes to it. No need for decorations. We've got enough golds in Castle of Black Iron. As gold's density is large, it's suitable to be bodyfitting tools..."

"Are you going to use it?"

"Yes!" Zhang Tie nodded.

Edward took a look at Zhang Tie with great admiration as if he had understood a bit why Zhang Tie would ask for this odd thing. "Okay, Castle Lord, when do you need it?"

"The faster the better..."

"Castle Lord, give me 3 days. I promise to make it in 3 days..." Edward nodded forcefully with excitement. He almost made a military pledge.

"Hmm, thank you..."

"It's my great honor to serve you, Castle Lord!" Edward bent over his body. Closely after that, he took Zhang Tie's draft and left.

...

3 days later, after taking a King Kong Fruit and digesting it, Zhang Tie opened his eyes when he saw Edward standing in front of him.

"Castle Lord, I've made it!"

"Hmm, show me!" Zhang Tie picked himself up and went off the sacrificial altar.

"Please come with me, Castle Lord!"

Edward led Zhang Tie to his workshop under the palace tree.

With high-temperature underground fires, Edward's workshop was giving out golden light as two huge things attracted Zhang Tie's attention...
