Later, He Became A Royal Healer - Chapter 59 - Gazing at a beauty.

Thousands of years ago, a small planet collided with Earth and destroyed the world. In five days, ninety percent of humans had been wiped out, leaving behind the last ten percent to earnestly struggle on death’s door.

Jinyu was one of those people who survived. Due to a special heredity trait, he could understand beast language. After the apocalyptic disasters, Jinyu had been living for a month with the few small beast brothers that he’d subdued. Previously, Jinyu had thought that he would live like that until he died. Yet, inexplicably, one day he opened his eyes to find that he was in a monstrous, lawless world that was full of vitality and life.

Jinyu’s transmigration into the future let him skip over almost one hundred thousand years. In the year 106825, beasts rule the galaxies and ‘pure’ humans are extinct. As the one and only ‘pure’ human left in the entire universe, Jinyu braves this new chaotic world to find a place for himself and thus begins to work at Beast Store number 138.

By the year 3029 CE, Earth’s technology has developed rapidly, borders no longer exist, and Earth has been unified, marking the beginning of the era of the Federation.

At that time, a huge sword flew from the heavens, piercing the sun and causing a huge sensation on Earth.

Perhaps because the scabbard of the sword was already in tatters, countless shards have broken off from it following the collision with the sun and spread across the universe. Many of these shards have landed on various places across Earth.

With the arrival of the bronze sword and its shards, a new unlimited energy source has suddenly appeared on Earth. This energy source has since been named Spirit Qi.

Spirit Qi is like air, thick in some places and thin in others. As the Federation and other factions gather more shards, they discover more information on cultivation, pill refinement, Spirit Stone refinement, and other techniques. The words on the shards have an ancient feel to them, making it a trend for people to use ancient language.

The appearance of Spirit Qi rapidly makes the original energy sources obsolete and has completely changed people’s lives. Not only has the Spirit Internet been formed, Spirit Qi has also changed the course of Human Civilization, causing the world to enter a civilization of cultivation. This would later come to be known as the Spirit Inception Era.

During her cultivation practice, Nie Yinzhi encountered a mishap and nearly fell into qi deviation. After emerging from seclusion, she discovered she could see floating subtitles above her head.From these danmu (bullet screen comments), she learned that she was merely a substitute supporting character in a novel.Everyone in her sect doted on and loved her only because her eyes resembled those of the beloved senior sister who had perished ten years ago.And in three days, that blind senior sister would return to the sect—Nie Yinzhi would have her core forcibly removed by her master, her eyes gouged out by her senior brother, and ultimately die alone.Armed with spoilers from the danmu, Nie Yinzhi set up a forbidden array, sacrificing her soul to summon the novel’s antagonist – the great Demon Lord.Covered in blood, amid everyone’s terrified gazes, she coldly smiled and said, “If that’s how it is, then none of you shall live!”The Demon Lord appeared slowly in his dark robes, reaching out to wipe blood from the corner of her mouth: “You’re so young, why harbor such deep resentment? If there are any misunderstandings, we can sit down for tea and talk things through. Why resort to violence?”Nie Yinzhi: “???”Is this the ruthless, evil Demon Lord everyone spoke of?![The Demon Lord says no with his mouth but his actions prove otherwise. Don’t worry, it’s not frustrating, feel free to dive in.]Gu Jiang: Today my wife is asking me to kill againNie Yinzhi: Today the Demon Lord is preaching virtue to me againCultivation World: Being persecuted again todayLaid-back retired veteran couch potato Demon Lord male lead VS grudge-holding can’t-take-any-grievance female lead[[Warning: As you can tell from the synopsis, the female lead isn’t designed to be morally good!
