Resurrection of Spiritual Energy? I've Already Reached the Level

After living for 3,700 years, I have no interest in spiritual energy recovery. The S-class secret realm that the world's strongest men fought desperately to attack was the cellar where I used to pile up debris. The ancient skills that are being snatched up by all countries are my diary notes. Until that day, I saw a person in the night market - three thousand years ago, I personally buried him in the deepest part of Kunlun Mountain.
