This Series gets better in the later seasons. The protagonist shows a lot of character growth.
So, this series is based on the common Reincarnation/Isekai/Cultivation tropes.
The story has a lot of depth. Diverse characters. The wars have a lot of strategy behind them. There is an element of romance which is quite well executed (he finds a wife in the first episode itself, but the road to love is not easy).
The MC (Main Character) is very powerful at the beginning due to past life experience. However, he is also quite arrogant, due to which he makes mistakes, knowingly walks into obvious traps, ending up defeated. In ... the later seasons however, the MC almost loses his life in a near fatal encounter, due to his own negligence.
After this incident, we see a lot of character growth in him. He becomes very wise, has various strategies, takes down enemies with a lot of precautions.
Overall, it's worth a watch. The animation quality is okayish. Available sub translations are good, but could've been better(which remains an issue for most chinese anime).
What I find missing is the element of comedy. There are not many characters who bring a comic relief, and the MC himself is of a serious nature.
P.S.: Don't stop watching it if you find the MC annoying in the beginning. He will grow a lot later on.

I've been watching a lot of cultivation donghua similar to this but this one hardly lures me in like other ones. For this type, I would recommend Martial Master aka 武神主宰 way more. That one lured me in from the beginning. The beginning story is already pretty similar to other similar donghua but sadly nothing interesting imo.

MC is naturally OP and has some kind of past life, as well, and his substantial knowledge helps him deal with his enemies.

I only pushed myself through this season because there are 4 seasons so it's been going on for so long I thought it would be really good.

Calling it bad would be an understatement.

The story is all bs.
The animation is a disaster.
The main character is incompetent, even with a second chance at life. As per the convenience of the author, the MC shows unparalleled skills thanks to his reincarnation, whereas most of the times he acts as a buffoon where even an idiot could handle the situation better.
Most of the plot seems 'borrowed' from other sources, and without their context, they make no sense.
The voice acting is uneven. At times the MC's voice gets self-loathing while his actions say otherwise, which gets irritating at times.

My biggest regret is not heeding @Anzoner's ... review.
It doesn't deserve my time and effort to write a detailed review.

P.S. I generally hold the source material in higher regard than its adaptations, but no matter how I view it, the author seems to lack the skill to create anything original. Additionally, to extend the storyline, they rely on whatever random ideas come to mind.
