Rankings in the Trilogy
I was a bit confused when reading many of your comments, so I'll explain it all here.
The trilogy has different level divisions at the Titled Douluo stage, and the same realm is expressed differently in the three eras. This book tries to match each era with the corresponding original work, and at the same time explains the reasons for the changes in the performance in different eras.
In Dou Yi, level 95 and above are considered Peak Douluo, including Level 99. Level 99 is also known as Peerless Douluo. There are no terms like Super Douluo or Limit Douluo.
Starting with Dou Er, there is a distinction between Super Douluo and Limit Douluo. Super Douluo are level 95-98, and Limit Douluo are Level 99.
The divisions in Dou San Dou Er are the same, but in Limit Douluo, there are further subdivisions, dividing them into Quasi-Demigod (Pseudo-Demigod), Demigod, and Quasi-God (Pseudo-God).
