Castle of Black Iron
chapter-1461

In many cases, when one reached a certain stage, he would have a greater insight and ability and could treat many things calmly.

When in Blackhot City, one of Zhang Tie's dream was to buy a big house for his family members. Zhang Tie pursued this target at his full efforts and had dreamed about it for many times, including the location of the house in the downtown, the layout of the rooms, the furniture, curtains, lawn and trees in the courtyard, Zhang Tie had considered about these details carefully. No matter what, it was a "major event" of hundreds even thousands of gold coins, but now, even though it was a class A city after Zhang Tie made a decision and communicated with the other elders of Iron-Dragon Sect, he would not care about its construction anymore.

Even though this new city was a big program of tens of millions even hundreds of millions of gold coins and would become the "trade center of sacrifices for bloody sacrifice" of Taixia Country and humans as a whole in the future, Zhang Tie would not care about it anymore. He didn't even care about its location.

Zhang Tie had already lost his interest in money.

Zhang Tie cared most about that small tree in Castle of Black Iron after knowing that bloody sacrifice furnace couldn't do any more help to him for the time being.

The small tree had displayed many miracles and brought him many surprises. This time, Zhang Tie expected that the small tree could bring him another miracle and surprise.

After leaving the lobby where the bloody sacrifice furnace was placed, Zhang Tie came to the outside of the backroom where he used to enter close cultivation on the top of Xuantian Peak. After leaving some words to those disciples of Iron-Dragon Sect outside there, he entered the tunnel leading to the backroom.

Not until the 0.5 m thick alloy composite gate was slowly closed by disciples from outside by rotating the capstan did Zhang Tie lock the capstan from inside as he let out a deep sigh and walked towards inside, relieving his calmness.

The tunnel led downwards all the way to the hinterland of Xuantian Peak. On both sides of the tunnel were inlaid with eternal fluorites, which brightly lit the entire tunnel. It was tranquil in the tunnel except for the fine footsteps when he stepped on the steel steps. Walking inside it, Zhang Tie felt entering the ghostdom.

When a knight was officially in close cultivation, he was fragile and very dangerous. When a knight was in close cultivation, he couldn't prevent threats from outside. Actually, when a knight was in a realm of the secret method, he was actually as weak as a sleeping commoner and could be easily killed. Additionally, when a knight was possessed by the devil when in close cultivation, he could easily do great damages to commoners.

Previously, due to poor safety precautions, some knights in close cultivation were assassinated by commoners or enemies.

A knight was possessed by the devil when in close cultivation. As a result, he was in hallucination and broke out of the backroom easily. He then killed all of his family members and disciples. When his consciousness recovered, he couldn't accept the fact that all of his family members and disciples had been killed by him; therefore, he chose to commit suicide.

To prevent these emergencies from happening again, the backrooms of knights today had to meet very strict requirements.

The first requirement was that outsiders even high-level knights couldn't easily break, enter or sense the backroom of knights; the second was that only sober-minded knights could exit it.

To meet such strict requirements, the backroom for close cultivation could even match the underground havens which were built to prevent nuclear weapon attacks before the Castastrophe.

There were many alloy gates in the tunnel. Like doors of safes, those alloy gates were all locked by Zhang Tie after he passed through them. They could only be opened from inside using a code when he was sober-minded.

Many places on the walls and the ground were supported by hard metal frameworks. The tortuous structure lasting 1,000 m inside the tunnel determined that this tunnel couldn't even be destroyed by a sage-level knight by one strike.

There were 3 heavy lead isolating layers outside the backroom at the end of the tunnel, each layer was 0.5 m in thickness. These heavy lead isolating layers could isolate the consciousness and spiritual energy of all knights.

After entering the backroom and closing the last protective gate, Zhang Tie finally let out a sigh of relief.

The fact that his wife was too powerful was also an obsession for Zhang Tie. As long as Yan Feiqing was on his side, she would discover it right away the moment he entered Castle of Black Iron. This was why Zhang Tie couldn't find a chance to enter Castle of Black Iron in Xuanyuan Hill.

Certainly, Zhang Tie trusted Yan Feiqing; however, he felt that he should have a bit of individual space and secrets. It was like why his dad liked to have some case-dough at home. Was it that his dad didn't trust his mom? Of course not.

The backroom was less than 1,000 square meters in size. The entire room was divided into two regions, one bright, the other dark. In the dark, there were some plants which usually grew in the underground world. These plants could constantly synthesize oxygen; therefore, the air in the backroom was always fresh.

Besides, there was a hidden escape passage leading to the outside.

'Small tree, I'm here!'

Zhang Tie had not entered this backroom for a long time. After looking around, he didn't find any problem. Therefore, Zhang Tie ran a bit of spiritual wave in his mind sea as he entered Castle of Black Iron in a split second and appeared in the lobby of the Palace Tree.

"Welcome back, castle lord!"

Handsome Heller had long been waiting for him along with the three slave servants.

Eyes closed, Zhang Tie breathed the fresh air which carried reiki deeply before opening his eyes.

"It's so nice to see you again. I almost thought that I couldn't come back this time!" Zhang Tie said as he tightly put his arms around Heller and forcefully patted Heller's back.

When he was hugged by Zhang Tie, Heller became stiff for a second as his eyesight changed. Closely after that, he recovered his composure.

After that, Zhang Tie gave a hug to his three slave servants respectively, causing them flurried.

Although Heller, Agan, Aziz and Edward always regarded themselves as Zhang Tie's slave servants, Zhang Tie felt they were more like his reliable friends as they were helping him sincerely.

"Easy, it's just a hug! It's my fortune to survive myself this time. Do you know what I was thinking about when I woke up in Xuanyuan Hill?" Zhang Tie had uttered before the other 4 answered, "I was thinking that you would be too poor if I died this time. I should find wives for you at least!"

Watching the dumbfounded looks of them, Zhang Tie finally burst into laughter. Closely after that, he turned around and walked towards the small tree. He was then attracted by the change of the small tree instantly...

A bizarre fruit was hanging over the small tree while its brilliant and tender golden light was covering the entire tree. The small tree as a whole was like a golden torch, which gave out strange waves from time to time...

Zhang Tie was shocked by such a scene very much as he stopped his feet at once.

"That's the fruit of redemption from the gratitude of humans..." Heller's voice sounded behind Zhang Tie.
