The system is the proficiency panel

Feng Tian walked through the Shadow Valley, the flames burning around him illuminating the surroundings. He frowned and looked around, all he saw were simple stone houses and dilapidated living facilities, and the air was filled with a smell of decay.

"This damn place is full of traps!"

Feng Tian kicked away the rubble that blocked his way, his golden eyes full of impatience. He had already triggered three traps, and although his immortal body allowed him to revive and recover easily, every injury made him more irritable.

He stopped and closed his eyes, his consciousness spreading out like a tide. Suddenly, he opened his eyes sharply and looked deep into the valley - there was an area there that resisted his exploration.

"interesting."

Feng Tian curled up the corner of his mouth into a sneer, and flames suddenly rose around him, turning into a line of fire that rushed in that direction.

As he went deeper, the temperature around him gradually dropped, and the air was filled with the pungent smell of medicine and rot. Feng Tian stepped into a deep cave, and the flames illuminated the horrific scene around him - countless experimental subjects were placed on the stone platform, some were disemboweled, some had twisted limbs, and all had the painful expressions of death.

"These beasts..."

Feng Tian's fists clenched and crackled, and flames burst out of his body uncontrollably. He raised his hand and waved it, and a blazing wave of fire swept through, turning those miserable corpses into ashes.

"rest in peace."

As he continued to move forward, a slight noise caught his attention. Feng Tian instantly restrained his breath and quietly approached the source of the sound. Turning a corner, he saw a thin figure trying desperately to get into a small hole.

"stop!"

Feng Tian took a quick step forward and easily pulled the thin figure out. When he saw that it was a ten-year-old elf boy, he was stunned for a moment.

The little boy's face was filled with fear, and he suddenly banged his head against the rock wall like crazy. Feng Tian was quick to hold him down.

"Are you looking for death? I'm here to save you!"

The little boy stopped struggling and raised his head tremblingly. With the help of the firelight, he could see Feng Tian's appearance clearly - his short red hair was like a burning flame, his golden eyes were dancing with a fiery light, and his body exuded a warm and powerful aura, which was completely different from those black-robed believers.

"You...you really are not one of them?"

The little boy's voice was hoarse and dry, but there was a glimmer of hope in his eyes.

"nonsense!"

Feng Tian snorted impatiently.

"Where are the cultists?"

"please!"

The little boy suddenly grabbed Feng Tian's collar, his thin fingers turning white from the force.

"Save Liris! She is my sister. They took her away to be sacrificed! I only heard them say they were going to the east..."

Feng Tian frowned even more. Although he was impatient, he hated this kind of scene. And he knew that if the sacrifice was successful, it would definitely not be a good thing for them.

"East? Where exactly?"

"I-I don't know..."

The little boy burst into tears.

"But I know the ceremony is tonight! Please, save her!"

"Okay, hold on tight!"

The flames suddenly rose, and Feng Tian turned into a beam of fire and rushed out of the cave. The boy hugged his neck tightly, feeling the unprecedented speed and warmth.

"What's your name? Why weren't you taken away by those cultists?"

Feng Tian asked while galloping.

"Valeno Windwhisper, my sister's name is Liris Moonshadow. My sister and I are elves from a nearby village. We were captured and have been imprisoned here. My sister secretly dug a small hole in the cave where we could hide. Those cultists came to arrest people today, and my sister hid me in it. Those cultists seemed to be in a hurry and didn't pay attention to me or check me carefully. They quickly took my sister away first."

The boy answered timidly with tears in his eyes.

After understanding the reason, Feng Tian sped up and flew towards Lin Ji and others, with flames leaving a brilliant trail behind him.

……

Feng Tian turned into a beam of fire and fell from the sky. When the flames dissipated, he was holding a thin elf boy in his arms. The boy tightly grasped Feng Tian's clothes, with tears on his face, but the fire of hope was burning in his eyes.

"Lin Ji!"

Feng Tian shouted immediately after landing.

"I found this child deep in Shadow Valley. His sister was captured and sacrificed by the cultists!"

Lin Ji frowned, and his consciousness spread like water waves, instantly covering a radius of ten thousand miles. In his perception, the battle between Pu Jianxing and the priestess was still going on, and the energy fluctuations were like thunder in a storm, fierce and dangerous. He retracted his consciousness and looked at everyone calmly.

"We can't wait any longer."

Lin Ji's voice was calm and firm.

"Once the cultists complete their sacrifice ritual, the consequences will be disastrous. Master Pu is very powerful, so there is no need to worry. Let's go and stop the sacrifice first."

Xiao Ningxue stood beside him, her white hair fluttering slightly in the night wind, and her fingertips had quietly condensed into a water ripple formation.

"My husband is right. I have read some books from Elvis. Sacrificial rituals often involve gods. We must stop it as soon as possible."

Yun Shitian moved his shoulders, his golden armor glowing coldly in the night, and he grinned.

"It's a good time to stretch your muscles!"

Feng Tian snorted coldly, and flames danced at the ends of his hair.

"None of those cultists will be able to escape!"

The seven people took the little boy into the air, turned into streams of light and rushed eastward. Along the way, their spiritual senses swept across every inch of land below like a net, leaving no suspicious traces.

……

The night was dark, and the light of the light core gradually dimmed, accumulating energy for the light of the next day. In the valley below, there were many ghosts. The cultists who fled from the Shadow Valley circled around and gathered again in a remote village in the east.

In the square in the center of the village, a huge magic circle drawn with blood was emitting a strange red light. A dozen black-robed believers stood around the magic circle, their faces full of fanaticism and piety. Hundreds of pure soul light balls were suspended above the magic circle. They were as weak as fireflies, but contained powerful energy.

In the center of the magic circle, a teenage elf girl was pierced through the limbs by four black iron nails and fixed at the center of the circle. Her blood slowly flowed out of the wounds and merged into the lines of the magic circle. The girl's face was as pale as paper, and her lips trembled slightly due to the pain, but she clenched her teeth and said nothing. There was no despair in her eyes, only firm belief.

"Valeno, may Lady Silver Moon bless you..."

In front of the magic circle, a man in a scarlet robe held up a magic book made of human skin and recited the sacrificial spell passionately. His voice was hoarse and crazy, as if he was talking to some indescribable existence. As the spell was recited, the soul light balls on the magic circle began to disappear one by one, as if they were swallowed by an invisible giant mouth.

The being seemed very satisfied with these pure souls, and only devoured half of them before bestowing blessings. Several blood-red rays of light descended from the sky, covering several believers. They felt the surging power in their bodies, and their faces became even more fanatical. They looked greedily at the elf girl in the center of the magic circle, hoping to receive greater blessings after sacrificing her.

The soul balls were being devoured until the last few, and it was the elf girl's turn. Her life was like a candle in the wind, which could be extinguished at any time, but her eyes were still clear, full of hope, without a trace of negative emotion. It was this purity and tenacity that made her the carefully selected sacrifice by the cultists.
