After one year and one month, the last punctuation point of "Sword Spy" was finally typed on the keyboard. I remember the situation when I first started writing, as vividly as if it were yesterday. I wrote "Sword Spy" neither to pursue the excitement and weirdness of the plot, nor to exaggerate the protagonist's almost tragic experience in a long and lengthy manner. I just want to describe the struggle of human nature and the fight against fate through such a story. Lin Yi finally won, not because of his strength, but because of his belief in never giving up. For Lin Yi, he had no intention of competing for supremacy, it was just destiny, and his greatest wish from beginning to end was just to stay with the person he loved, even if it only lasted a lifetime. Yan Luanshuang also loved him, but she quietly left when the final victory was about to come. If you are as careful as you are, you should be able to understand the secrets. Perhaps, she is Wu Xian, the last mysterious person in "The Classic of Mountains and Seas" whose veil has not been revealed. Because it was she who appeared at the right time to guide Lin Yi to find Gong Lanyue and seize the Sun-popping Great Light Bow and the "Youyou Blood Book"; later, it was she who stole the volume from Qionghai Palace in Yongye Hidden Waterfall Cave for many years. The tiance was handed over to Lin Yi with the help of Mrs. Tang. But in the end, feelings conquered everything. Therefore, she resolutely abandoned her cultivation and declared her independence to Longtou. Lin Yi truly accepted her at that time. Or maybe, she just doesn't want to feel the helplessness of sharing love with others, so she would rather choose to leave silently on her own, fulfilling the thousand-year love between Lin Yi and Rong Ruodi. But no matter what, her final union with Lin Yi will take time. How to continue tomorrow, keep going or change direction, everyone will have their own different choices. I would like to thank all my friends who continue to care about me and the book "Sword Spy". The end of the story does not mean our separation, on the contrary, it will be a new beginning. Of course, I am also very grateful to all colleagues at Xianxian Culture. It is your hard and responsible work that makes it possible for a stupid cow like A Niu to appear in the cowshed. In addition, please allow Aniu to take the trouble to thank another person who is very important to Aniu - Mrs. Niu. Many readers called me "Niu Da" in their comments, which really puts me to shame. And "Tai" is a little bit more than "big", which shows that Niu Tai is often "a little smarter" and "a little harder" than A Niu. Sometimes, he may even be "a little bit more awesome" than A Niu. . Finally, I would like to dedicate this book to a teacher whom I respect. Although she is far away across the ocean, she may never know that there is a student she once taught who is blessing her from a distance with the greatest gratitude and enthusiasm.
