"Kekekekeke, I understand, I finally understand!"

"I've become a xian, I've finally become a xian!"

Meng Cheng Xian threw his head back, laughing wildly into the sky. But his face bore no signs of madness. 

Instead, he looked deeply content and at peace.

He appeared like an old man, yet he was terrifying to behold. 

Half of his body resembled that of a normal elderly man, but the other half was gray-black, with skin like that of a demon, as if it were something far from human. 

If one side of his body were hidden, he might pass as a human, but together, the halves made him look like a monster.

His body was broken and battered, clothed in nothing but a tattered pair of pants. 

His flesh was riddled with wounds, and his body had been pierced through in countless places, blood flowing everywhere. 

His life was nearing its end. Even without anyone attacking him, he wouldn't last much longer.

Looking at the millions of people encircling him, ready to kill, and then up at the sky, where nuclear bombs were raining down, he laughed aloud:

"Kekekeke, thank you, thank you all so much!"

He was genuinely grateful, for humanity had played a significant role in helping him achieve xian level. 

Throughout his life, countless people had sacrificed themselves to pave his way to this very moment.

Though his words sounded sincere, they stood in stark contrast to the chaos on the battlefield. 

Blood flowed like rivers, quite literally, staining the ground in every direction. 

One couldn't fathom how many lives had been lost to create such a scene.

The leaders at the front of the encirclement, though not faring much better than Meng Cheng Xian himself, had endured grievous injuries and were barely clinging to life. 

Behind them stood millions, all ready to lay down their lives to bring down Meng Cheng Xian.

Hearing his words of gratitude, humanity erupted in rage, shouting back at him:

"Thank you, my foot!"

"You damned demon! You've killed countless people, and as long as you live, humanity will never know peace."

"Today, we may all die here, but you will die with us!"

"Demon, you're gravely injured already. With this additional bombardment of nuclear weapons, you're as good as dead."

"Finally, humanity can know peace. At last, I can have my revenge."

.....

Millions at the scene, along with billions watching from afar, cursed him endlessly. 

They were overjoyed. At long last, this day had arrived. 

Now, they could finally live in peace, study, work, and be with their families without fear.

Meng Cheng Xian remained unbothered, smiling brightly, oblivious to their words. His mind held only one thought:

"I have become a xian!"

"I've finally become a xian!"

"After so many years, I finally did it."

"My friend, I've finally succeeded."

Facing the crowd, he laughed aloud and said:

"Kekekeke, regardless, thank you all. Today, I'm certainly going to die, but I have finally achieved xianhood."

His voice echoed for hundreds of miles, amplified by the last of his strength. 

At this moment, he wanted to make an announcement to humanity—those who in his view, had unhesitatingly sacrificed themselves to assist him. 

He wanted to declare that he had finally succeeded. He had become a xian!

Boom! Boom! Boom…

Countless nuclear bombs exploded across the sky, a blinding light engulfing a vast area. 

Meng Cheng Xian's broken body was reduced to ashes under the impact of the nuclear blasts.

The attackers surrounding him were also turned to ash, while a few who had enough strength remaining managed to survive. 

An enormous area spanning multiple nations was heavily contaminated by radiation, and human casualties numbered in the of billion. 

Humanity suffered unspeakable losses—no war or plague in history could compare to the devastation caused by Meng Cheng Xian's dream.

In the end, everyone felt joy. Meng Cheng Xian was pleased that he had fulfilled his lifelong dream, and humanity rejoiced that their future no longer lay in darkness under his looming shadow.

"Hahaha, we did it! We finally succeeded."

"The demon has been eradicated, and humanity is saved."

"Countless humans have died, but at last, justice has been served."

"We won, we won! Hahaha, the nightmare is truly over."

Humanity wept with joy everywhere. Meng Cheng Xian's departure from this world promised a brighter future for everyone.

Meng Cheng Xian, however, held a very different perspective on humanity. 

To him, humans were admirable, selflessly offering themselves to support his journey to xianhood. 

But from humanity's viewpoint, Meng Cheng Xian was nothing less than a living catastrophe. 

His life had brought devastation across the lands, resulting in an incalculable number of deaths.

To humanity, Meng Cheng Xian was the most sinister figure in history, deserving of the infamous title "Humanity's Genocidal Calamity".

 He was the one who, single-handedly, had caused the death of billion—a being they hoped to never see again.

.....

"Wait... I'm not dead?" Meng Cheng Xian thought.

Something felt off. His strength was now incredibly weak. 

Once a powerhouse able to withstand nuclear bombs and countless warriors, he now found himself unable to lift even a 10-kilogram weight.

Looking down at his tiny hands, then at his small feet, he wondered:

"Could it be that my friend has brought me back to life once more? Kekeke, my friend truly is the best."

If humanity were to hear this, they would be utterly stunned. Throughout their meticulous investigations into Meng Cheng Xian's life, they found no evidence of anyone he could call a friend. 

This "friend" existed solely in his mind, never speaking a single word to him, known only to Meng Cheng Xian himself.

"Hmm, this human body seems a bit unusual. Could this place not be Earth? Well, it doesn't really matter if it's Earth or not—I'll achieve xianhood once more."

But before he could speak of becoming a xian again, he needed to acquire some basic knowledge first. 

In his previous life, while he was hunted by humanity, he knew that humans excelled in scientific knowledge.

"Where exactly am I now? Who am I?" He paused, correcting himself.

"No matter the body, I am, and always will be, Meng Cheng Xian."
