- Description from novelbuddy

[space + ancient times kingdom building + escaping from famine]

The big shot from the future, Bai Wutong, transmigrated to ancient times with her space pocket! Before she could feel happy, she found herself in a chaotic world! There was murder, robbery, schemes, sky-high prices, and many other things happening all around! The moment she arrived, she had killed two people. Then, she also kindly saved someone, but was deceived and stalked as the person insisted on following her. If that’s the case, then don’t blame her for using aggression in return!

After she finally managed to settle down, she was assigned to the frontier to develop the lands. The remote lands were out of anybody’s control, and there was nothing more that Bai Wutong could ask for. After a few years, Bai Wutong accidentally led the richest man of the previous dynasty, the prime minister, the commander of the secret guards, a great scholar of the dynasty, the holy maiden, as well as the divine doctor… and turned the barren land into a rich, noble town that everyone desired. When the emperor and his ministers came to admire the place, they were dumbfounded. That man who was pouring tea beside Bai Wutong… Wasn’t that the eldest son of the previous emperor, who had been dead for many years?!

The Red Dragon came from the vast wild wastes, coveting all the strength in the world. It once had countless titles: Mountain's Wrathful Flame, Infernal Calamity, Crimson Emperor, Ashen Dragon......The world trembled under the shadow of the giant dragons. He stirred up the craze of the magic industrial revolution; in the empire he established, Wyverns roared, artillery fired in unison, and steel beasts appeared in the sky and on the land, while disasters from another world rampaged everywhere.“Submit, or die.”Cassius spread his wings, blotting out the sun, and gazed down at the trembling humans, elves, and dwarves below, saying thus.......It is a story about a Red Dragon with a player template conquering, ruling, and transforming an alternate world.(Pseudo of DnD, The Fourth Calamity, Red Dragon)
