Chapter 81

The walls of the lower level of the Sky City were tightly joined, with no visible signs of adhesion or assembly from the outside, but another force seemed to hold them together.

"Who are you!?"

A highly cautious and alert voice echoed from all around. Zheng Chen looked around, but the source of the voice was unclear!

"This voice?" Sheeta was puzzled. "This voice sounds like the person who captured me..."

"Do you have the Flight Stone?" Zheng Chen withdrew his Green Wind Sword from the wall seam and asked calmly.

"Answer my question quickly!" The voice sounded agitated. After taking control of the Sky City, he thought he was the supreme ruler, but the monster that appeared on the upper level of the Sky City made him feel threatened.

Could the Sky City's robot soldiers really deal with the opponent?

The ultimate weapon on the lower level was powerful, but it was only effective on the ground and could not attack the upper levels of the Sky City.

Zheng Chen was the young man beside the rampaging monster girl. The other girl could transform into a weapon, which surprised and intrigued him. This was not a product of Laputa, as there were no records of it. A girl who could transform into a weapon...

He was not as ignorant as Pazu and knew that this was likely a characteristic of a race from another continent.

The hands of the outer domain had reached here too!?

No matter what, the person controlling the Sky City did not want outsiders to get involved in the affairs here.

Without speaking, Zheng Chen began to murmur. Sheeta, who was beside him, heard it clearly. The murmur was a melodious chant. As the chant ended, a solid wind emerged from the Green Wind Sword.

"South Wind String!!"

The wind swirled around the Green Wind Sword, and the wind ring surrounding it suddenly contracted. At that moment, Zheng Chen thrust the sword into the seam of the wall in front of him. The tip of the sword penetrated less than half an inch before stopping. The wall in front of him did not seem to be made of metal but rather a special stone.

Its hardness was superior to steel. Even the sharpness of the Green Wind Sword could only leave a shallow mark when it struck.

The condensed wind roared out from the tip of the sword, and the walls around them shook violently as the wind pressure surged into the seam. They did not shatter but dispersed on their own, confirming that the walls were indeed assembled like building blocks!

The internal structure was composed of numerous blocks with intricate patterns.

The tight connection was definitely related to some technology of the Sky City. Even after a strong impact, they did not shatter but dispersed to distribute the impact. After the impact ended, they would reassemble. The same applied to the internal structure!

"Go!!" After completely opening the wall, Zheng Chen swung the Green Wind Sword, and the spiral wind remained, forming a wind tunnel. The surrounding blocks continuously compressed the wind ring. Without hesitation, Zheng Chen picked up Sheeta and stepped into the wind ring, rushing in quickly!

The unstable wind ring was completely crushed, and Zheng Chen and Sheeta broke through. However, they found themselves in a passage filled with roots. Due to the long-term growth of these roots, many of the blocks had been pushed apart.

Finding a larger opening, Zheng Chen cut through the roots and squeezed in. He paused for a moment, looked at his left hand, and asked Sheeta, "Do you know where that person is?"

"..." Sheeta shook her head in confusion. She knew the incantation for the Flight Stone but was not familiar with the structure here. "He should be in the center, right?"

"Let's go and see." After some thought, Zheng Chen temporarily dissolved the contract. They had already penetrated the lower level of the Sky City, so there was no need to continue consuming power.

He quickly wrapped the Sealing Symbol back around his arm, frowning slightly. Without finding a way to eliminate the influence of the black particles, the duration of the contract would only get shorter.

"You despicable intruders, get out of here now!!" The man's voice continued to echo around, but he could not be located. He must have some monitoring system.

Zheng Chen ignored the man's words and adjusted his direction based on the changes in his tone.

The man's tone became increasingly urgent, "Damn it, this is your fault!"

The lower level was not very large, probably due to the many technologies it contained. The structure was not as complicated as a maze. After some exploration, Zheng Chen had a good understanding of the layout.

Suddenly, Zheng Chen stopped, picked up Rea with his left hand and Sheeta with his right, and ran backward without looking back. A dark golden lightning bolt shot out from one side. Though only as thick as a finger, its destructive power was immense, and the intense explosion covered the nearby passage.

All the roots in the passage were burned away.

After the explosion's light faded, the temperature around them had risen significantly, and the blocks with patterns in the lower level were damaged.

"Damn it!" The man's angry voice echoed from the passage.

This attack could be used continuously here, but he had many concerns and did not dare to use it recklessly. If it hit, it was fine, but if it missed, the dark golden lightning would damage the foundation of the Sky City. During its peak, there might have been guards here.

Now, he was the only one controlling the place. If he attacked without restraint, he might destroy the foundation before dealing with Zheng Chen.

Is this guy some kind of monster? He could sense the danger in advance and react immediately, which was a huge blow to his confidence.

Moreover, Zheng Chen was getting closer to him... The man's combat strength was clearly not a match for Zheng Chen.

Even without the girl who could transform into a weapon, Zheng Chen's reaction speed and agility alone could finish him off. Romuska, who was watching the projection in front of him, was sweating profusely, his voice becoming more panicked.

Along the way, the small attack pillars that popped out were all anticipated by Zheng Chen. Not only did they fail to produce any good effects, but they also caused considerable damage to the area.

Zheng Chen looked down at a block with a severely cracked shell, revealing a faint green light and some other parts inside. "These are Flight Stones?"

Sheeta looked at the faint green light inside the block with surprise. She was very familiar with this light.

"..." Zheng Chen reached out calmly, and the patterns on his body spread out, touching the faint green light. As expected, the Flight Stones could be extracted!

Although the amount was small, it allowed him to make some guesses.

The tight assembly of these blocks was largely due to the Flight Stones!

After extracting the Flight Stones, whether the effect of the patterned blocks was lost needed further testing. Zheng Chen stepped on one, and even with the cracked shell, the block remained very hard. When he stepped on it, the block sank slightly.

Indeed! Without the Flight Stones, these patterned blocks had lost their original function. The machinery inside could influence or control the power of the Flight Stones.

Narrowing his eyes, Zheng Chen reached out again, this time not in a dark mine. Sheeta clearly saw the gray patterns spreading from Zheng Chen's hand into the cracks of the patterned blocks. The faint green light in the cracks disappeared completely.

All the damaged patterned blocks nearby became ineffective. After securing Rea, Zheng Chen stepped on the ground again. This time, the patterned block he stepped on did not sink slightly but collapsed in a chain reaction. The surrounding patterned blocks, which had lost their effect, all fell downward, bringing Zheng Chen and the others to the next level of the passage.

Not only was Sheeta speechless, but Romuska, who had been observing Zheng Chen's actions, was also stunned. His attack had revealed a weakness, and Zheng Chen had destroyed the patterned blocks!

He had to admit that many of the patterned blocks had been damaged by his attack.

There was no time to be stunned. When he saw Zheng Chen leading Rea and Sheeta to a stone door, he quickly picked up his gun, staring cautiously at the entrance to the control room. This was the core of the lower level, as he had learned from the Laputa-related documents and translation book he had.

The protection of the control area should be very strong, right?

Just as this thought crossed his mind, a strong wind rushed in, chilling him to the bone!

"Rest well." Zheng Chen caught Rea, who had become weak after the contract was dissolved and was about to fall to the ground. The entrance was very sturdy, and breaking through it had exhausted Rea's already limited strength. After gently placing her on the ground, he quickly rushed to Romuska, who had raised his gun.

As he approached, he turned his face slightly, and a bullet grazed his cheek. Before he could fire a second shot, Zheng Chen grabbed him by the neck and pinned him to the ground. After subduing him, Zheng Chen had a chance to look around.

No wonder the giant tree could grow to such an extent in the Sky City; it was absorbing the energy emitted by the Flight Stones. A super-large Flight Stone...
