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

Suddenly, there was a loud "boom" and huge magic barriers came towards them.

"Defend!" Hu Huan shouted, and the mecha's mechanical arms swung rapidly, making a "click" sound of metal friction, and started a fierce fight with the magic barrier.

Caesar gripped the joystick tightly, and the mecha's energy shield unfolded again, making a "buzzing" sound, resisting the attack of the magic barrier. Axe controlled the mecha's energy cannon, aimed at the weak point of the magic barrier, and made a "bang bang" bombardment sound, trying to weaken the power of the magic barrier.

After a fierce battle, they successfully resisted the attack of the magic barrier and continued to go deeper into the temple.

In the dim basement, Caesar, Hu Huan and Axe groped their way forward. The beams of their flashlights danced on the walls, and suddenly, a strange light caught their attention. The walls were inlaid with glowing gems, which emitted a faint blue glow, like the brightest stars in the night sky.

"These gems..." Hu Huan's voice echoed in the empty space, sounding particularly clear.

Caesar moved closer to the wall and gently touched the gems with his hands. "They feel warm, not like ordinary stones."

Axe frowned, "What's the connection between these gems and Phoenix Feathers?"

They continued to go deeper, and with every step they took, the gems on the wall became denser and the light became stronger. Suddenly, a low roar came from deep underground, as if something huge was moving.

"Did you hear that?" Hu Huan asked nervously.

"Yes, the sound comes from down there." Caesar pointed deeper into the basement.

They quickened their pace. As they went deeper, the gemstones on the wall began to change color, from dark blue to deep red, like burning flames. The atmosphere became tense, and an indescribable sense of oppression filled the air.

“This color change, could it be…” Before Axe could finish his words, a blinding red light shot out from the front and they were forced to stop.

"Look there!" Hu Huan pointed forward. A huge stone door blocked the way. On the door was carved a phoenix with its wings spread out, ready to fly. Its feathers were lifelike, as if it would fly away at any time.

Caesar walked forward and carefully observed the stone door. "The color changes of this phoenix's feathers are consistent with those of the gems."

Ax nodded. "It seems that these gems are some kind of mechanism used to activate this door."

They began to try to touch different gems, and each time they touched one, the phoenix feathers would flicker. Finally, when they touched the gem in the center, the stone door slowly opened with a heavy friction sound.

Behind the door was a huge cave with an altar in the center. On the altar was a shining feather - the feather of a phoenix.

"We found it!" Hu Huan said excitedly.

But Caesar seemed more cautious, "Be careful, everything here is going too smoothly."

They walked towards the altar, and suddenly, the ground began to shake, and the light of the gems on the surrounding walls became brighter, as if warning them.

"Look, the gems are moving!" exclaimed Axe.

The gems on the wall began to rearrange, forming a complex pattern. Caesar immediately realized, "This is an ancient code, we must solve it."

The three began to study the pattern, trying to find the rules. As time passed, the tense atmosphere was almost suffocating.

"Here, this order!" Hu Huan suddenly pointed to a corner of the pattern.

Caesar and Axe immediately followed Hu Huan's instructions and touched the gems one by one. When the last gem was touched, the altar suddenly rose up, and the Phoenix Feathers were suspended in the air, emitting a dazzling light.

"Success!" Hu Huan cheered.

But at this moment, the entrance to the cave suddenly closed, and the surrounding walls began to squeeze inward, as if to trap them to death.

"We have to get out of here!" Caesar yelled.

They rushed to the entrance, but the door was completely closed and could not be opened. Caesar looked back at the floating Phoenix feather, "Perhaps, this feather is the only way out."

He reached out to grab the feather, and the moment he touched the feather, a light surrounded them. The three of them felt dizzy and then lost consciousness.

When they woke up again, they found themselves back on the ground, the sun was shining, and they were surrounded by familiar scenery. The Phoenix Feather lay quietly in Caesar's hand, emitting a warm glow.

"We... escaped?" Hu Huan looked around in disbelief.

Caesar nodded, "Yes, but we must be careful, the power of this feather is far beyond our imagination."

Axe looked at the feather and said, "This is just the beginning."

They know that this Phoenix Feather will lead them to deeper mysteries, and they must be prepared to face unknown challenges.

Deep inside the temple, light shone through the ancient stone windows onto the ground, creating a mysterious and solemn atmosphere. Caesar, Hu Huan, and Axe clenched their weapons tightly, facing the guardian who suddenly appeared, and the atmosphere was extremely tense.

The guardian was wearing ancient armor, with a cold light flashing in his eyes. In his hand, he held a sword emitting a cold light, with the tip of the sword pointing at the three people, and made a low threatening sound.

“Hand over the Phoenix Feather, or you won’t be able to leave here.” The guardian’s voice was like an icy blade, piercing into the ears of the three.

Caesar tightly grasped the talisman given by the old wizard and silently recited the spell in his heart. The runes on the talisman began to glow, forming a light curtain that protected them.

"We won't give up easily," Caesar said firmly.

The guardian sneered and swung his sword towards the light curtain. The sword collided with the light curtain, making a harsh metal friction sound. The light curtain trembled, but did not break.

Hu Huan and Axe took the opportunity to launch an attack. Hu Huan swung his long sword, the sword flashed like lightning, and pierced the guardian's chest. Axe attacked from the side, the short knife in his hand flashed a cold light, trying to cut off the guardian's retreat.

The guardian dodged Hu Huan's attack and swung his sword back, knocking Axe's dagger away. The guardian's movements were as fast as lightning, and every swing of the sword carried a deadly threat.

"Be careful!" Caesar shouted, and the talisman in his hand glowed again, and an arrow of light shot towards the guardian.

The guardian dodged to the side, and the arrow of light passed by his shoulder and hit the stone pillar beside him. The stone pillar collapsed with a loud bang, and dust flew everywhere.

Hu Huan and Axe teamed up again. Hu Huan's swordsmanship was sharp, and each sword was aimed directly at the Guardian's vital points. Axe used his flexible body movements to constantly move around the Guardian, looking for flaws.

Although the guardian's swordsmanship was superb, he gradually showed signs of fatigue under the joint attack of the three. Caesar saw the right opportunity and activated the spell in his hand again, trapping the guardian with a halo.

"Now!" Caesar shouted.

Hu Huan and Axe launched the final attack at the same time. Hu Huan's long sword pierced the guardian's chest, and Axe's short knife slashed the guardian's throat. The guardian let out a shrill scream and fell to the ground.

The battle was over. The three of them gasped and looked at the guardian lying on the ground, their hearts filled with joy of victory.

"We succeeded." Hu Huan said, wiping the sweat from his forehead.
