Earth's catastrophe, crazy black crystals begin to wreak havoc

The shadows were getting closer and closer, and the four people finally saw their true faces - it was a group of mechanical crows, their eyes flashing red, like living demons.

"These crows are mechanical!" Caesar said in surprise, with a hint of curiosity in his eyes.

"They don't look friendly, we have to be careful." Hu Huan warned, his body involuntarily moving closer to Lun Lisa.

The mechanical crows quickly surrounded the four people. Their wings made a harsh metallic friction sound, as if they were mocking these tiny humans.

"We have to find a way to break through their encirclement!" Lun Lisa said calmly, her eyes looking for flaws among the mechanical crows.

"Let me try!" Xing Tianba shouted, and his sword drew an arc and hit the nearest mechanical crow.

The sword collided with the mechanical crow, making a harsh metallic collision sound, but the mechanical crow was not repelled. Instead, it attacked even more fiercely.

"These crows are too tough!" Xing Tianba said with a frown, his arms trembling slightly due to the reaction force.

"We must find their weakness!" Caesar analyzed, his eyes fixed on the movements of the mechanical crow.

The four of them stood back to back, forming a defensive circle. They had to deal with attacks from all directions at the same time. The mechanical crows' attacks were like a storm, making it difficult for people to cope with them.

"Look, their eyes!" Hu Huan suddenly shouted, his finger pointing at the eyes of the mechanical crow.

"The eyes may be their control center!" Lun Lisa reacted immediately, and the tip of her sword pointed at the eyes of the nearest mechanical crow.

The four immediately adjusted their tactics, and their attack targets turned to the mechanical crow's eyes. Each attack was extremely accurate, and the mechanical crow's offensive began to weaken.

"We're almost there!" Xing Tianba said excitedly, his sword hitting the eye of a mechanical crow again.

As the last mechanical crow's eye was hit, they fell to the ground one by one with heavy crashes, like machines that had lost power.

"We did it!" said Lunisa excitedly, her eyes filled with the joy of victory.

"Yes, we have overcome the difficulties again." Xing Tianba responded, his voice full of pride.

In the afterglow of the setting sun, the four people stood in the middle of the defeated mechanical crow, thinking that victory was in sight, but they did not expect that the mechanical crow would begin to ooze out brown liquid. This liquid was like a living thing, wriggling on the ground, and quickly gathered to form a larger mechanical crow. What was even more shocking was that this huge mechanical crow actually had three heads, each of which flashed a cunning red light.

"What the hell is this thing?" Hu Huan's voice was obviously trembling, and his body involuntarily took a step back.

"It seems we are not finished yet." Lunisa gripped the hilt of the sword tightly, her eyes revealing firmness and determination.

"A three-headed monster. This is not easy to deal with." Xing Tianba frowned, and the tip of his sword pointed at the head in the middle.

Caesar calmly analyzed: "These mechanical crows seem to be able to repair and combine themselves. We must find their control core."

The three-headed mechanical crow let out a harsh metallic roar, and its three heads opened at the same time, as if mocking these tiny humans. It flapped its wings violently, stirring up a gust of wind, and attacked the four people.

"Be careful!" Rensa shouted, and her sword danced into a curtain of light, trying to block the attack of the mechanical crow.

Xing Tianba and Hu Huan also reacted quickly, their swords collided with the mechanical crow's metal wings, making a harsh collision sound. Caesar was looking for an opportunity to find the mechanical crow's weakness.

"Their attack is too fierce!" Hu Huan shouted, his arms aching from the continuous attacks.

"We have to distract them!" Renissa suggested, her eyes moving between the three heads of the mechanical crow.

The four of them quickly dispersed and tried to attack the mechanical crow from different directions. Xing Tianba and Hu Huan were responsible for attracting the attention of the two heads, while Lun Lisa and Caesar tried to attack the head in the middle.

"Watch me!" Xing Tianba shouted, and his sword fiercely stabbed at one of the mechanical crow's heads.

The tip of the sword collided with the metal skin of the mechanical crow, making a harsh metallic sound, but it did not cause any substantial damage. The mechanical crow reacted very quickly, and one of its heads quickly counterattacked, almost knocking Xing Tianba down.

"These guys are too hard!" Xing Tianba gasped, with a painful expression on his face.

"We must find their weakness!" Caesar said loudly, his eyes fixed on the movements of the mechanical crow.

The four adjusted their tactics again, and began to try to attack the joints and connections of the mechanical crows, hoping to find their weaknesses. The mechanical crows' offensive was like a storm, making it difficult for people to cope with it.

"Look, their necks!" Hu Huan suddenly shouted, his finger pointing at the necks of the mechanical crows.

"The neck may be their connection point!" Lun Lisa reacted immediately, and the tip of her sword pointed at the neck of the nearest mechanical crow.

The four immediately adjusted their tactics, and their attack target turned to the mechanical crow's neck. Each attack was extremely accurate, and the mechanical crow's offensive began to weaken.

"We're almost there!" Xing Tianba said excitedly, his sword striking the neck of a mechanical crow again.

When the last mechanical crow was hit on the neck, it did not fall to the ground like the others, but let out a sharp metallic hiss, flapped its wings and flew high into a huge cenote. The cenote was bottomless, and the surrounding rocks looked particularly eerie under the setting sun.

"It ran away!" Hu Huan exclaimed, his eyes following the figure of the mechanical crow.

"We can't let it escape!" Lunisa gripped the hilt of the sword tightly, a hint of determination flashed in her eyes.

"That tiankeng looks complicated. We have to be careful." Xing Tianba reminded, his sword ready for battle at any time.

Caesar calmly observed the surroundings of the cenote: "There may be more secrets hidden here. We must proceed with caution."

The four of them quickly chased after the tiankeng, their footsteps echoing on the rocks. At the edge of the tiankeng, the wind whistled, like a whisper from the abyss.

"Look, the mechanical crow has stopped in the center of the tiankeng!" Hu Huan pointed to the depths of the tiankeng, his voice carrying a hint of nervousness.

"It seems to be waiting for something." Lunisa frowned, her eyes fixed on the movements of the mechanical crow.

"We have to go down and take a look." Xing Tianba suggested, with determination in his eyes.

"Wait, we have to prepare first." Caesar stopped him, his eyes searching around the sinkhole for available resources.

The four of them acted quickly, finding some ropes and tools and preparing to descend into the tiankeng. Lun Lisa and Xing Tianba were responsible for fixing the ropes, while Hu Huan and Caesar were responsible for checking the equipment.

"Are you ready?" asked Renissa, with a hint of nervousness in her voice.

"We can set off at any time." Xing Tianba responded, his eyes full of determination.

The four of them slowly descended along the rope, and the wall of the cenote gradually became blurred under their feet. The sound of the wind whistled in their ears, making people feel an inexplicable sense of oppression.

"It's too deep here, we have to be careful." Hu Huan warned, his voice sounding a little weak in the wind.

"Look, the mechanical crow is still there!" Lunlisa pointed down, with a hint of surprise in her voice.

"It seems to be guarding something." Caesar analyzed, his eyes fixed on the movements of the mechanical crow.
