Help me check the names of these two novels.

There are 2 books Fantasy: The protagonist seems to have blue hair and eyes, and the characteristic is that there is a faint scar in the eye. At the beginning, he was alone in the forest killing a magical beast like a lion. It seems that there is a demon cave with several levels. Later, he went to the Mercenary Union to establish a mercenary group. For some reason, he fought with a dragon knight of a country. As a result, he lost. That person's subordinate ran to the magical beast forest to hide. He also lost his memory and stayed in a small village. Then, he taught a few children in the village kung fu and later joined the army... I don't know about the rest, but it's very good. Now I want to find it but I can't find it. Can someone help me find it?(This book is a bit similar to the Heavenly Demon God, but it's more exciting than that book. The main character is not that kind of pervert.) There was also This Is Wuxia: It was about a person who practiced demonic arts. At the beginning, it was an introduction to martial arts. It seemed that the first and second of the ten great divine arts were both demonic arts. However, those two books were lost. For some reason, when the protagonist was very young, he came to a place outside and became a teacher for a young lady. Later on, he found a book about the secret level of the Ice Secret Art or something else. Later on, he was not really separated. In the middle of the process, he fell off the cliff and saw the two mo skills on the cliff. Moreover, they were combined into one. He divided the kung fu into many levels and came out when he reached the third level... I didn't read the rest. If there's anyone who has read these two books and still remembers their names, tell me, I'll be eternally grateful…I haven't read for a long time. I remember that these are the only interesting ones. The ones that are out now are all edited from the past, and they don't look very good... I hope everyone can help me…
