Gazing at the Starbucks café at the airports had become a ritual for her. A desperate attempt as she hoped against hope to see him again, probably get one more chance to kiss him again. Looking at the store all lost, she walked ahead, but stumbled and bumped against someone.  The cup of coffee that he had in his hand spilled all over just like the first time when she had met him.  "Jesus Christ", he muttered.  The moment she heard the voice she looked up and saw his face. It was the same face that had promised to stay next to her, till death did them apart. Tears flooded her eyes and she could barely speak, "I knew you would come back for me Raymond". She raised herself on her toes in an attempt to kiss him, but he blocked her lips with his palm. "Whoa, whoa, Miss !!! I guess you have mistaken me for someone else." "What are you saying, Raymond? It's me, your Akira. The love of your life, your fiancée," she said and stretched her hand showing the ring on her finger. He stared at the ring for quite some time and then looked at her face apologetically and said,  "Miss please, I am already a married man." And then he silently walked away. ----- [Instagram - niharikabhol] [Join me on discord at] https://discord.gg/cPVJ69e [Warning: This novel has mature content. Reader's discretion advised]

Zhou Yun transmigrated to a fantasy world and was bound to the God Tier Epiphany System. He could enter into a state of meditation and achieve epiphanies that others desired regardless of what he did. Other cultivators immersed themselves fully in hardcore training in order to achieve some improvements in their swordsmanship. On the other hand, Zhou Yun achieved enlightenment in swordsmanship by merely picking up a sword and playing with it a little. His swordsmanship attained perfection in an instant. Other cultivators trained hard in order to break through to the next plane. Zhou Yun merely swept a glance at the fallen leaves in the courtyard. Then, he had an epiphany and broke through to the next plane on the spot. He had insights into everything in the world, and his rate of plane progression skyrocketed. When other cultivators finally became powerful existences after going through various hardships, Zhou Yun had already become the supreme existence through having countless epiphanies.
