Time travel + system + invincible flow + harem ambiguity + slapping Tang San in the face + magic modification of the original plot + original divine boundary line.
Invincible at the start, golden fingers in the system, crushing the original protagonist (Tang San), leapfrogging monsters, ambiguity in the harem, slapping the villain in the face, a combination of magic modification of the original plot + original plot.
Lin Chen, a modern time traveler, lives in the Holy Soul Village of Douluo Continent and is the same age as Tang San
Martial Spirit: Chaos Devouring Martial Spirit awakens at the beginning (God-level Martial Spirit, can swallow all martial spirits, soul rings, soul bones, soul power, energy, no side effects, the more it is swallowed, the stronger it becomes)...
That's right.
