Chu Mo, carrying a portal through time, travels to an era of mythological revival and the descent of ancient heroes. Here, the top experts can traverse the universe, pluck stars from the sky, and shatter starfields with a mere thought.

Chu Mo, who is at the bottom of society, can only travel through the river of history by using the Time Gate, creating one mythical version of himself after another in the past, and condensing them into heroic spirits.

[Human Saint Emperor] [Confucian Master] [Godslayer Celestial Venerable] [Lord of the Investiture of Gods] [Ancient Ancestor of All Paths]...

While others are lamenting how to obtain their first Heroic Spirit...

Looking at the numerous mythological versions of himself, Chu Mo fell into deep thought.

...

Meanwhile, as time passed, the powerful figures who had inherited the legacy of many ancient heroes also sensed that something was amiss.

"Wait a minute, the memories of the heroic spirit I obtained before showed that the one I inherited actually spent his whole life hunting down a man? Holy crap, the Qing Dynasty's dragon vein was severed by that person? Is this the reason for the Qing Dynasty's downfall?" — An anonymous successor of the Qianlong heroic spirit.

"Is this what the real history is like...? That man, single-handedly, slaughtered his way across the heavens and the earth, fighting for the lives of humankind, which is why I inherited his legacy and brought peace and prosperity to the world." — Successor of Zhu Yuanzhang's spirit.

"He alone has dominated for all eternity!" — Successor of the Holy Spirit of the Moral Celestial Venerable.

Maybe a Tomcat? What? Besides weapons graveyards, there's also machine tool graveyards and gold graveyards? Are these all exchangeable? Great, exchange whatever you want!

Pre-collection: "Dragon Girl's Interstellar Substitute Bride"—The Albino Koi Dragon Leaping Through the Dragon Gate vs. the Western Tyrant Dragon, Ruler of a Nation. Announcement: This article will be V-ed starting June 28, 2023, and will be updated regularly every day at 9:00 AM on Saturday after V. Recommending my completed novels of the same genre: "The Lord's Wife from the East" and "The Pharaoh's Fairytale Princess." In this article: In her previous life, Aresia was a thug who wantonly bullied her commoner rivals, but her efforts were always unsuccessful, ultimately ending in disastrous defeat. After reincarnating, Aresia, who rose from a commoner to a great mage, has been eager to beat her former self to wake her up. What's so good about men? Magic is her lifelong love! Later, a magical accident brought her back to her previous life. At this time, she was still a beloved duchess, about to enter the Royal Academy's magic department, and she hadn't even started those mindless tasks. It might seem tempting to rejuvenate and start over again, but after two hundred years of hard work in a world of high magic, where magic is ubiquitous, she finally achieved the status of Holy Mage. To suddenly be thrown back to the pre-liberation era is as unacceptable as a wealthy man suddenly becoming a pauper. Furthermore, Aresia has long been accustomed to the conveniences of magic. In her world, magical technology has transcended planetary boundaries and reached the cosmos, but this world's magical research is far behind. Magic is a special power accessible only to a select few, feared and revered, with no one considering using it to improve their lives. There aren't even the most basic magical streetlights, let alone basic infrastructure like magical furniture, magic networks, teleportation arrays, airships, and magical mounts. Most importantly, return the magic tower she painstakingly built to her! In the end, she realizes it's just a fresh start; she'll build it all sooner or later! Pairing: A research-loving magic lady versus a young knight with immense potential. (Title and copy are tentative and subject to revision, but the main theme remains unchanged.) Theme: To benefit the public.
