Castle of Black Iron

Ten minutes later, after flying over 60 miles deeper, Zhang Tie suddenly felt entering a deeper basement by staircase as a bizarre underground space appeared in front of him.

This underground space was much smaller than the former one; however, it still covered about 6,000 square miles. When Zhang Tie saw this underground space, he was shocked so much that he almost cried out.

The entire underground space comprised of an integral piece of metal as same as that he saw before. Actually, Zhang Tie was more stunned by the shape of this space rather than its component.

This underground space was completely in the shape of the space inside the All-spirits Tower of Great Wilderness Sutra that he cultivated.

The entire space was composed of five facades, each of which was a metal wall as high as 30,000 m. Additionally, each wall was covered with a myriad of still vivid totems and images of animals and mutated beasts like reliefs.

Right in the middle of this underground space, there was a huge metal mountain with 8 facades like a sacrificial altar. Right on the top of this metal mountain rested still a huge colorful tower of time.

This underground space was dark. However, yellow, green, blue and purple lights were flowing like water on the surface of the tower of time. The tower as a whole was like a huge eternal fluorite lamp, which tinted the entire underground space into a magical stage.

Knights' brilliant battle qis made this place more dazzling while colorful light spots were constantly flying around the tower of time. From Zhang Tie's perspective, a horde of fireflies was flying around a huge lighting device.

This place was so magnificent that Zhang Tie could barely imagine the power that created such a colossal engineering masterpiece.

The moment Zhang Tie entered this space, the All-spirits Tower in his mind sea had started to rock as if it resonated closely to this place.

Under the leadership of Bai Yuanan, Zhang Tie and Bai Suxian flew towards that huge tower of time.

At this moment, all the knights had almost gathered around the octahedral altar.

The entrance of the tower of time was in an emergency as a lot of knights were circling around three blue-faced knights.

"Old freak Plum, it's said that you've gained a lot of element crystals before entering the tower of time. Why not present them to us? We're all curious about the measures that you've gained from Great Wilderness Sect..."

A slightly haunched knight with gloomy expression opened his mouth among the onlookers, which instantly received resonance from the others.

"Yea, as we're all here, we should share it; quick, take them out..."

"Your four sage freaks have already enjoyed too much. Don't be too gracious. With so many people at present, be careful of your lives..." someone said in a vile way.

Some knights booed and hooted at once while many eyes were searching over the three people incessantly.

At the same time, some knights were just watching it silently in the periphery of these people, some of which were from Lord Guangnan's Mansion.

Bai Suxian's third uncle Bai Runshan and some other knights were watching it quietly outside the crowd.

Seeing Zhang Tie and Bai Suxian descending from the sky, Bai Runshan revealed a smile at Zhang Tie as he tipped them a wink to let them watch the performance quietly.

When Zhang Tie and Bai Suxian arrived, some knights fixated onto Zhang Tie as if they were guessing Zhang Tie's identity.

Zhang Tie just watched it quietly. This scene was too familiar for Zhang Tie. Vile and greedy human natures were always exposed in front of rich profit.

"Hahahaha..." one of the three knights being surrounded in white robe and grey hair with some plum blossoms embroidered on his shoulder burst into laughter as he pointed at the faintly haunched knight by his flute and said, "Qi Tianhao, is that your real nature? You vile b*stard! I... I know you're such a merciless person, I should not have let you go in Thunder Valley one decade ago. After ten years, you became so audacious that you instigated the others to rob us. Go ahead! As long as you could kill us three, of course, you will have our belongings. Whereas, who among you would like to fight us to death? Even if we three die here, when my third younger brother comes out of the tower of time after promoting to an earth knight, he would avenge for us surely!"

After saying that, one knight in pale blue robe and whiskers and one bald knight in yellow robe exchanged a glance with each other. Closely after that, the three people stood close to each other with resolute looks as they held fast their weapons and released their protective battle qis. At the same time, they had connected their knights' consciousness. It appeared that they had already prepared for a duel in the form of an entity.

Watching the three knights' response, all the other knights who were urging them to hand in their achievements became hesitant for a second.

Of course, good items were pursued by everyone. However, given the three knights' response, if they really had a duel, more than three people among their opponents would die for sure. Four sage freaks were famous in South Border because they excelled at fighting together in a formation of two, three, or four people. When four of them fought their enemies together, they were said to set a complex formation of heavens, land, wind and thunder. Therefore, they were tricky guys in South Border.

In this case, nobody would like to die for nothing; instead, they preferred to pick up profits alive at the cost of others' lives. The death of Daoists invested the lives of a sagacious monk. That was how most of the people were thinking about at this moment.

As they were thinking about it, nobody dared approach the three people. Even though there were some earth knights among the crowd, when they thought about the other person in the tower of time who would probably have promoted to an earth knight when he exited it, they didn't feel like stirring up such life-or-death trouble...
