Ask for the names of the two novels

They only remembered the main points:
The first book: The protagonist's family was a small declining family. There were two sons in the family (the protagonist was the eldest son). In the basement of the family (I seem to remember), he found the ring that sealed the ancestor of his family's Earth Element Archmage. From then on, the protagonist embarked on the path of a genius mage. In the academy, he found that he not only had the talent of the Earth Element but also the talent of the Wind Element. His ancestor also told him a method to practice his spiritual power by carving. Her younger brother inherited the family's special blood that had disappeared for many years and could practice martial arts. I can't remember what happened after that…
[The second book: The protagonist had high hopes of becoming a mage due to his powerful mental strength when he was young, but his perception of magical elements was surprisingly low.] Later, he discovered that he could see the elemental combination array of each spell, and he could draw this array and seal it in the blank magic nucleus to use the spell. In his memory, he seemed to have met the King of Shreme and learned an Absolute Defense spell from him. He didn't look at it again, and he forgot what it was called...
The main thing is the name of the second book. Well, let me remind you again. The way to deal with the Slime King is: The protagonist hides in a small cave. The Slime King can't enter because of its huge body. When the protagonist hacked at it, the Slime King would use the spell "Absolute Defense." The protagonist would watch it cast the spell to learn the magic circle. When the time limit passed, the protagonist would hack again…until the Slime King had no strength, or when the protagonist had learned it, it seemed to have subdued the Slime King.
Thank you everyone for your help ~ This seems to be quite old ~
