An adopted child, Heidi was a smart and obedient girl because she had to be. Used as a scapegoat by her family, she was sent to become the political bridge between two empires. Taken in by the House of the infamous White King, Lord Nicholas Rune, she would be cared for and supervised until her wedding with his cousin, Warren Lawson. A man whose gentle appearance and benevolent manner earned him the title White King of the Empire, Lord Nicholas was a man kindest to the souls around him. Very few knew about the truth that lay beneath his beautiful visage. Who could predict a little human girl would bring out the best and the worst of a noble pureblood? ----- “Now, tell me, Heidi, why do I have a bad taste in women?” As Lord Nicholas took a step forward, she took a step back. Heidi had said too much, and she regretted it. Would he let her go free? Gulping, she warned him, "What you're doing could be considered harassment, milord." "I wouldn’t. I’d call it persuasion.” He took another step towards her, his frame towering over her. "I believe the dictionary in your library would disagree with you, milord." She retreated another step back, shrinking away, hoping he would give up. “I keep the good one in my room. You can come to see for yourself if you don’t believe me.” Her back struck the wall behind her. "You haven’t answered my question, Heidi." The Lord was too persistent, Heidi cursed to herself. He was unwilling to let her go.

Billions of people around the world were transmigrated to the game world of “Shining Era.” Everyone became lords and possessed their own land. They recruited troops, gathered resources, occupied mines, attacked cities and built up their empires. In this world of lords, the most important resource was the troop lairs where they could recruit troops. However, the potential of these lairs was fixed. If anyone wanted to obtain a top-level troop, they could only do so by defeating powerful wild troops and occupying their lairs. However, Richard discovered that he could actually improve the level of troop lairs directly. From then on, various powerful troops were groomed by him. When the other players were still leaping with joy from obtaining a high-level troop, behind Richard were a Desert Pharoah, a Demonic Scorpion King, a Mechanical Giant, a Demon Baron, a Blood Archduke, a Five-colored Evil Dragon, and a Fallen Angel. From that day on, a prosperous and dazzling oasis city was established in the desert. As for Richard, he became the ruler of the desert.
