Check-In before Birth, Born to be the Dark Antagonist

"Where... where am I?"Ji Xiu woke up from a daze.Opening his eyes, he looked around at the extremely unfamiliar surroundings.It was as if everything here was in chaos, with no visibility.But he could feel that he seemed to be immersed in a warm ocean.Warm seawater soaked his body, and he felt an extreme soft and warm sensation all over."Wait!""Why are my hands so small?""Oh my god!""Why is there a cord on my belly?!""????"Ji Xiu's mind raced.Finally, he came to a conclusion.He had traveled through time.And, he had even traveled to a world where he was still an unborn baby in his mother's womb.Phew!Ji Xiu took a deep breath and calmed himself down.He began to review what had happened.In his memory, he was reading a fantasy novel called "Immortal Emperor: Unparalleled".Suddenly, a white light appeared before his eyes.And then he arrived here.As his thoughts reached this point,A character interface suddenly appeared before Ji Xiu's eyes.[Name: Ji Xiu][Age: 0 years old][Identity: Heir of the first military family of the Northern Xia Dynasty][Life status: Unborn][Cultivation: None][Techniques: None][Essence of Destiny: 0 points][Fate level: Black - Soul destroyed and fallen!]Ji Xiu carefully examined his character interface.He immediately understood what was going on.It turned out that he had traveled to the world of the fantasy novel "Immortal Emperor: Unparalleled".And, his identity was actually the future biggest villain of this fantasy world...The same-named and same-surnamed Demon God Ji Xiu!Of course, that wasn't the point.If Ji Xiu remembered correctly... the point was that the fate of this big villain was extremely tragic!He was even considered the representative of the "BE aesthetic" in the online literature world!And one of the most tragic villains in the online literature world!"The setting of the villainous big boss in the novel is...""A crazy, critical, lovesick character!""A substitute who jumps off a building and is a masochist!""Before becoming the villainous big boss, Ji Xiu was a young master of a military mansion, unknown and carefree, with fine clothes and a spirited horse!""But... later, his family was destroyed, his parents died tragically, his cultivation was abolished, and he was finally thrown into the most terrifying ancient abyss on the continent.""He suffered the excruciating pain of ten thousand demons devouring his bones for a whole thousand years before returning from the abyss and growing step by step into the most terrifying villainous big boss!""Sitting in the middle of the Demon King, with the gods standing on both sides!""Ruling the nine heavens for countless ages, worshipped by all races, and all the Celestial Immortal Emperors bowing down as his subjects!""And the novel tells the story of...""The awakening of a powerful Goldfinger as the illegitimate son of a sect's male protagonist...""And the female protagonist, who reincarnated from a world ten thousand years in the future, back to the world a thousand years ago when Demon King Ji Xiu was at his peak...""The two of them join forces to kill the still immature Demon King Ji Xiu in his cradle and save the future world!""On their wedding night, a divine nail is driven in!""Hearts are dug out, bones are picked clean, and the sky is stained with blood!""Separated by yin and yang, the Demon God returns to ashes!""The light of righteousness shines upon all living beings!".........Ji Xiu recalled the plot of the novel.He couldn't help but think that if all these events were to happen to him, it would be truly miserable!You talk about time travel...Why did he have to travel to become such a pitiful and crazy villainous big boss?After he was born,Although he would be the most powerful and influential young heir of the entire Northern Xia Dynasty,The problem was that not long after, not only would his cultivation be abolished, but his family would also be destroyed?And even worse, he would be thrown into the abyss and suffer the pain of ten thousand demons devouring his bones for a whole thousand years?!Not only that...There was actually a chosen male protagonist who awakened his Goldfinger...And a female protagonist who came back from a world ten thousand years in the future, whose goal was to kill him!"The future...""Family destruction?""Hearts dug out?""Blood staining the sky?!""This is too tragic!"Thinking of this, Ji Xiu suddenly felt very bad.An ominous star!The future was destined to be dark!There was no hope at all!Perhaps that was why his fate level was pure black - Soul destroyed and fallen!This was truly the ultimate disastrous start!Just when he was feeling extremely helpless, a clear voice suddenly sounded in his mind."Ding! Congratulations, host, on awakening the Check-in System!""Would you like to check-in here?".....Upon hearing this,Ji Xiu trembled all over.System!!Check-in system!!He had read hundreds, if not thousands, of novels before he traveled.Naturally, he knew what the appearance of a system meant.Goldfinger!This was something that could change his destiny!Phew!Ji Xiu took a deep breath and without hesitation, he spoke up."System!""Check-in!"
