Castle of Black Iron

The old monster cleaned up the surrounding clouds in vain. After that, he flew around here for a few minutes before leaving. Hiding still behind a pine needle, Zhang Tie watched it silently. 1 hour later, the old monster reappeared in the sky. After confirming that nothing was here, he let out a long sigh before flying backward.

At this moment, a colorful poisonous snake climbed towards him from the trunk of the pine. The moment it widely opened its mouth and intended to eat the little beetle, the little beetle casually jumped up and turned around in the air before falling onto the head of the poisonous snake. At the same time, it released a bit qi. This little beetle was definitely a ferocious living being. Soon after it released its qi, the poisonous snake had become stiff all over like a lamb whose neck was bitten by a lion.

Zhang Tie flew away, leaving the poisonous snake alone. As a result, the stiff poisonous snake didn't coil around the twig any more; instead, it directly fell off the pine tree. After falling onto the ground, it woke up immediately and escaped into the weeds in an embarrassed way.

After flying away from the pine tree, Zhang Tie identified the direction before flying towards Pingsha Valley in the incarnation of a little beetle.

After flying over 70 miles away, Zhang Tie came to a hidden place in the wild. After confirming that nobody was following him up, Zhang Tie's original body exited Castle of Black Iron. After activating a hiding effect, Zhang Tie entered the stratosphere once again. Closely after that, he flew towards Pingsha Valley silently and swiftly.

The power of heavenly knight was pretty awe-inspiring. Zhang Tie didn't know whether the old guy had seen clearly his look. In case of trouble, Zhang Tie changed his look and figure once again.

The thunder hawk was still resting in Castle of Black Iron. As Zhang Tie was concerned about the 4 double-headed parent puppet worm, he didn't communicate with the thunder hawk too much for the time being before leaving Castle of Black Iron.

Now that the thunder hawk had come back, after relieving the crisis in Pingsha Valley, Zhang Tie had enough time to figure out what happened to the thunder hawk.

On the way, Zhang Tie met another team of knights flying towards the same direction. In the evening, after releasing their gleaming battle qis, they looked like meteors. By contrast, with the effect of a master-level hiding rune, Zhang Tie hid his qi completely and integrated himself with the dark background in the evening. Even if someone flew towards him face-to-face, they could not discover Zhang Tie.

...

After flying a few hours, Zhang Tie approached Pingsha Valley, Longxi Prefecture once again at about 3 am after leaving Pingsha Valley for less than 1 day.

The tracing runes were still on the dome of the underground space, which indicated that nobody had moved those items in the secret space on the top of the underground space. Therefore, Zhang Tie became reassured.

When he was dozens of miles away from Pingsha Valley, Zhang Tie landed in dense woods. Closely after that, he called that little beetle out of Castle of Black Iron and flew towards Pingsha Valley.

When he arrived there, he saw two light flying out of the entrance of the underground cave towards afar.

The two knights might have no discovery in the underground space. Therefore, they left.

Zhang Tie slowed down once again and flew into the underground cave at the speed of common beetles.

The underground space was as pitch-dark as it was tomorrow. Everything remained unchanged. Nobody else was inside. After flying around the underground space for a short while, Zhang Tie approached the dome and drilled into it from a crack. After entering it for a few meters, he saw limestone in the surroundings. The little beetle instantly drilled into the limestone.

The hard limestone was as soft as a piece of bean curd for the little beetle. It might be very difficult for other living beings to drill a hole on it; however, it was pretty easy for such a little beetle to make it.

In less than 10 minutes, a small piece of limestone at an inconspicuous corner of the secret karst cave suddenly moved while the little black beetle revealed its head out of there. With a humming sound, he shook off the dust while lying on the ground.

There was a green fluorite in one corner of the secret space. As a result, this little secret space being renovated by a natural karst cave turned green. The 4 black square metal containers were placed in the middle of the secret space tidily.

Zhang Tie reappeared in the secret space.

In case of leaving any trace, Zhang Tie floated 10 cm above the ground in the secret space.

Zhang Tie watched the 4 square containers with gleaming eyes. The moment he ran his spiritual energy, the 4 containers had floated in the air. The containers were matched with ventilated covers and advanced locks. If they did not have keys, commoners could only break the locks by force.

However, it was very easy for Zhang Tie to unlock them. In lotus-flower eyes, the internal mechanical structure of the lock became completely transparent. As a great master artisan, Zhang Tie had figured out the principle of the unlocking actuator only after throwing a glance at it. Closely after that, he activated his ability as a divine dominator, causing the unlocking actuators in the locks to move automatically. With a click, the 4 locks were unlocked at the same time before floating in the air.

No matter how advanced the locks were, as long as he threw a glance at them, they would unlock automatically like how pets greeted their master. What a marvelous ability! It might be unique among human beings. Any chief thief might be dwarfed by this ability.

There were many great master artisans and more than one divine dominator. Someone might also grasp the ability of lotus-flower eyes. However, Zhang Tie might be the only one among human beings who could combine the two professions and the one ability. As a result, he could create a marvel by unlocking an advanced lock only by throwing a glance at it.

After unlocking those advanced locks unconsciously, Zhang Tie stroked his chin as he realized that his ability was really something. In some special occasions, this ability might be shocking.

'From then on, there's no lock in the world. What a realm!'

After sighing with emotions for a few seconds inside, Zhang Tie started to move.

After the containers were unlocked, their lids were opened, revealing the 4 double-headed parent puppet worms.

Given their look, the double-headed parent puppet worms indeed looked as disgusting as rotten flesh in the tins of pickled vegetables. However, given their effect, the 4 double-headed parent puppet worms could really destroy cities and countries. Anyone of them might cause an irreparable catastrophe as long as they were taken out.

As Zhang Tie had sensed the destructive power of double-headed parent puppet worm, he dared not be careless. After a consideration, he determined to make the 4 double-headed parent puppet worms safer.

'What if a powerful shadow knight or a heavenly knight came back for the double-headed parent puppet worms? Would I just watch him take them away and create more troubles? Although it might not happen, it's possible.' Because Zhang Tie didn't know how many trump cards did demons and Heavens Reaching Church have, he had to consider this possibility.

Zhang Tie injected a "driving-section" great wildness seal that he had formed in the All Spirits Pagoda into each double-headed parent puppet worm from his mind sea so as to control them like controlling pets.

As Zhang Tie had just reached the 15th floor of All Spirits Pagoda, he could control all the living beings below LV 15. Double-headed parent puppet worms were LV 14 living beings; therefore, it could be controlled by Zhang Tie.

After reaching the 15th floor of All Spirits Tower, he met a bottleneck. Each step forward would be more difficult. If Zhang Tie wanted to reach a higher floor and control all the living beings below knight level, he had to recite great wildness sutra for 418,100,000 times. Without 20 years' penance, he could barely make it. Even though Zhang Tie always cultivated Great Wilderness Sutra whenever he was free, he was not sure that he could make it within 30 years...

After being affected by the great wilderness seals, the 4 double-headed parent puppet worms only slightly moved in the liquid of the containers before becoming still.

When the great wilderness seals were injected into the bodies of the 4 double-headed parent puppet worms, a statue of double-headed parent puppet worm appeared on the wall of the 15th floor of All Spirits Pagoda. At the same time, Zhang Tie established a mysterious link with the 4 double-headed parent puppet worms and sensed the reliance from the 4 double-headed parent puppet worms...

After doing this, Zhang Tie recovered everything in the secret space to their original looks before starting a cultivation by sitting in the air with crossed legs and waiting for someone to come here for the double-headed parent puppet worms...
