Castle of Black Iron

There were many kinds of marine organisms in Yaohai Ocean. The two immortal generals of Emperor NvWa City and Versatile Demon Emperor who came here with a time span of more than 10 minutes didn’t notice or didn’t care that a mutated big octopus who disguised itself as a reef was staring at this place from 1,000 m away.

After the two immortals of Emperor NvWa City left here for half an hour, the big octopus started to move rapidly at the bottom of the sea.

Cuttlefish could reach over 100 miles per hour in the water, not to mention a mutated big cuttlefish which could move over 150 miles per hour in water just like a torpedo. Therefore, after swimming for more than 2 hours, the mutated big cuttlefish came to a block of wood with dense tall corals. After traveling across the wood leisurely for a short while, the cuttlefish entered a coral cave.

At first glance, there were only colorful, beautiful fish swimming leisurely in the cave. Only the mutated big cuttlefish knew that one person was in this coral cave.

Of course, that person was Zhang Tie.

After sensing the coming cuttlefish, Zhang Tie opened his eyes as he reached out one hand and touched the big cuttlefish’s head. Closely after that, what the big cuttlefish saw just now appeared in Zhang Tie’s mind sea.

Besides high speed and being able to change its color to adapt to the surroundings, few people knew that big cuttlefish’s sight also ranked first in the ocean. Its sight was terrifyingly great. It could even change its pupils’ shape in order to observe the surroundings like a telescope in water. If a marine organism was selected to be scout or agent in ocean, mutated big cuttlefish was definitely the best one.

Boldness of execution stems from superb skill. After leaving that waters, he didn’t enter Castle of Black Iron immediately; instead, he hid his qi and stayed in this coral cave. In order to not arouse the attention of his enemy, he didn’t even activate his lotus-flower eyes to observe the waters; instead, he delivered the mission to this mutated big cuttlefish near this waters.

‘F*ck!’

When he saw Versatile Demon Emperor again in the memory of the cuttlefish, Zhang Tie’s heart trembled once.

Although Zhang Tie had guessed that Versatile Demon Emperor was waiting somewhere outside Emperor NvWa City for him, he was still startled by the reappearance of Versatile Demon Emperor. Meanwhile, he confirmed that he was ranked first in the blacklist of Versatile Demon Emperor. Otherwise, Versatile Demon Emperor would never wait for him patiently outside Emperor NvWa City.

Zhang Tie felt lucky about his fast prompt decision of leaving that waters immediately. If Zhang Tie wasted time to save the beauties out of righteousness, he must have been in the same poor situation like last time. If Versatile Demon Emperor launched a strike towards him again, Zhang Tie knew that he could definitely not survive Versatile Demon Emperor’s strike anymore.

‘The five immortal generals were not demons; nor were they affected by Golden-Soul Runed Virus. Their task was not to kill me; but to postpone my time leaving there. Meanwhile, they could confirm my direction. They probably not even know that it was Versatile Demon Emperor who was following them…’

‘If I really saved the two beauties, I might have already been dead.’

The mutated big cuttlefish couldn’t hear the words of Versatile Demon Emperor and the two immortal generals of Emperor NvWa City. However, as it could see them clearly, Zhang Tie could easily figure out what they were talking about through the images in its memory.

After reading these images from the memory of the mutated big cuttlefish, Zhang Tie input some reinforcing energy into the body of the mutated big cuttlefish as a reward.

Closely after that, a whim occurred to Zhang Tie, causing him to frown, ‘when I left Emperor NvWa City, I’ve already changed my look; additionally, I’ve made a trick to bamboozle them. How did they discover me? How could those people position my whereabouts?’

With this question, Zhang Tie returned to Castle of Black Iron.

…

“Welcome back, Castle Lord…” Heller’s voice sounded. Zhang Tie felt dizzy as he had already been in the lobby of the palace tree.

“Finally back…” Zhang Tie heaved a deep sigh. Although it was risky today, it was almost equal to taking a circle around the gate of the netherworld. If he made one mistake, he would have been killed.

“Castle Lord, you showed up…”

“Ah, well, I almost forgot about it…” After being warned by Heller, Zhang Tie discovered that he was still invisible. Therefore, he ran his spiritual energy and exited that state at once.

“Castle Lord, please take a look at this…” Heller said as he gave an item to Zhang Tie.

It was a smooth metal shell without even grains on its surface as large as a pocket watch.

After taking it, Zhang Tie asked, “What’s this?”

“I got it from each of the space-teleportation equipments of the five immortal generals that you teleported into Castle of Black Iron. It might help you solve your puzzle!”

“Oh!” Zhang Tie took a look at it as he found it could be opened. Therefore, he opened it.

At the sight of its internal structure, Zhang Tie almost mistook it as a compass.

There was a piece of crystal stone inside the metal shell. Zhang Tie saw a blood drop flowing in the center of the crystal stone; besides, dense runes were flowing in the small piece of crystal stone. Additionally, a tiny red needle was floating above the crystal stone.

The feature of the piece of crystal stone reminded Zhang Tie of Golden-Soul Rune Virus. When Zhang Tie opened the metal shell, he found that the tiny red neelde was pointing at him…
