All before him suddenly vanished, Lin Xian’s perspective was completely withdrawn, as if his soul was forcibly stuffed into Chu Yan’s vision. Then, endless fragments of light and shadow exploded and rearranged before his "eyes" like the birth of the universe, the torrent of time sweeping him back through countless eras at an astounding speed.

He saw the surface of a scorching, desolate primordial planet, where the simplest organic matter in the boiling ocean collided and aggregated under the catalyst of lightning and geothermal heat... The spark of life quietly ignited within the chaos.

Billions of years compressed into an instant, single-celled organisms floating and dividing in ancient seas, peculiar cephalopods and arthropods emerging in the warm shallow waters, crawling onto muddy shores, awkwardly pioneering the land, vertebrates solidifying their forms through long evolution, fish covered in scales leaping out of the water, growing four limbs, crawling under the shadows of fern forests.

Light and shadow quickly swirled, furry mammals rising amidst the dust of dinosaur extinction, nimble claws beginning to grasp tools, naive eyes reflecting the flames of trees split by lightning.

The focus sharpened: a group of thick-haired primitives hunting huge beasts with crude stone spears and bone tools, around the bonfire, emitting indistinct guttural sounds, rough wall paintings leaving the earliest marks of civilization on rock walls.

Time continued to fly by, settlements expanding into villages, from matriarchal clans’ pottery and worship to patriarchal tribes’ bronze and warfare, farmlands crisscrossing, feudal kingdom cities towering majestically, iron cavalry trampling past the smoke, ancient epics sung by bards.

The beast of steam roared in mines and factories, gears engaged, thick smoke veiled the sky, steel tracks extended into the distance.

The flood of light from the information age instantly engulfed everything, data torrents surged within intangible networks, huge Starships broke planetary gravity, sailing into the boundless deep space, towering geometric structures of perfect form and no metal or stone material sprung up on unfamiliar planets, piercing the cosmic vacuum, receiving energy converted from Constant Stars by the Heavenly Veil and transmitted via microwaves to the ground—this marks the beginning of the High Tower Civilization.

The scene froze within the magnificent interior of a high tower, precise synthetic factories operated silently, viscous nutrient liquid rich in all essential substances gushing from pipelines. As Lin Xian saw this, Chu Yan’s cold voice sounded beside him.

"What you see are simulations based on human perspective, not the true form of the Tower People, including our civilization’s evolution, but the conveyed meaning is the same."

"The Tower People succeeded in synthesizing all nutritional substances through inexpensive technology, eradicating hunger and extending lifespan through new techniques and population control, thus achieving efficient communication, promoting societal stability."

The scene before Lin Xian shifted, revealing an immensely grand and vibrant civilization city, teeming with life and order. It was a city cluster far more advanced and splendid than the previous Wisdom civilization No. 807, where hundreds of billions of humans were freed from hunger, possessing nearly infinite energy and productivity, welcoming an era of unparalleled happiness.

Chu Yan’s voice continued: "Subsequently, the Tower People began exploring the path to eternal happiness, wondering how to usher the world into everlasting peace alongside renewable or discoverable resources, while self-evolving wisdom and technology propel civilization. However... they realized to achieve this prerequisite means eliminating communication barriers, including individual differences and desires, which equates to eradicating evil thoughts and selfishness."

Lin Xian asked curiously: "Can this really be eliminated?"

"They found a way."

The scene shifted again, Lin Xian found himself in a massive precision laboratory, crowded with nutrients pods filled with countless live humans, half men and half women, assorted ages, races, and nationalities. Witnessing this, Lin Xian frowned.

"Why resort to biochemical experiments to eliminate human evil thoughts?"

"Because the Tower People discovered it requires eliminating individual differences and desires, removing evil thoughts and selfishness. The main aspects being gender, desire, pain, and death; once removed on a biological level, it establishes the foundation for eternal civilization, naming it life homogenization body, with another term..."

"Angel."

"Angel??" Lin Xian was quite shocked. "Wouldn’t they be the strange biological forms I just saw?"

"Indeed," Chu Yan replied.

Then, the scene continued changing, a countless years into the future, the technology of "life homogenization body" leapt forward rapidly. On the gene editing surgical table, gender traits were completely erased, nerve blocking techniques severed the neural pathways to perceive pain and death. Human gender began disappearing, bodies started merging, and the day arrived when life no longer needed to reproduce, those surviving became ’final life’, beginning continual fusion, due to relinquishing [social needs][reproductive needs], Angels lost aesthetics and form, morphing chaotically.

"Angels carefree, devoid of need, communicating through mutual consumption and fusion, such Devourment and merging allows knowledge, pleasure, and happiness to blend without pain or sorrow, while Angels possess nearly boundless lifespan..."
