I want to rate this 3.5 stars but can't so I'll round up to 4.

The good thing about this novel is the imaginative setting and the expansiveness of the world, as well as the OP as f*ck bullsh*t abilities that come out of the cultivators' ass every so often. This is both a blessing and a curse because these OP as f*ck bullsh*t abilities would come back to bite the story in the ass later on when they'd be very helpful and the author conveniently forgets about them.

One time the MC spared some cultivator's son and was granted the ability to read people's memories provided that they cooperated with him. HE NEVER USED IT. NOT EVEN ONCE. IT WAS NEVER MENTIONED IN THE STORY AGAIN. I want to ask the author WHY WOULD YOU INTRODUCE AN ABILITY IN A STORY, AND THEN NEVER MENTION IT EVER AGAIN. Here's a tip: If it's not essential, don't include it in the story. Including such an OP as f*ck bullsh*t ability in the story is basically saying "use me! use me!" and then to never ever mention it again, well that's just f*cking lazy writing. Especially since later (like hundreds of chapters later) on the MC gets an even more OP memory reading ability that doesn't even require the target to cooperate at all (and in fact low-level targets won't even know that they had their memories read) and can be done remotely instead of having to touch the person's head.

Another time (chapter 769) the MC acquired a mirror (回天镜) that can literally RESURRECT THE DEAD. By that I mean it can bring back those who had their souls destroyed (in the story, if your soul is intact you can just prepare another body. but if your soul is destroyed then you're really dead). There were no limitations described whatsoever, the ONLY problem mentioned in the story was that he had to acquire it from the Single Greatest Sect (太一门). NO COSTS OR LIMITATIONS WERE MENTIONED WHATSOEVER. He literally just had to use it and it would bring back the dead. No costs or limitations. HE ONLY EVER USED IT ONCE AND IT WAS NEVER EVER MENTIONED EVER AGAIN, EVEN WHEN IMPORTANT CHARACTERS DIED. Just what the f*ck is the author smoking. If it's single-use item at least say that. But the author never said that. He just said that the MC used it and then never mentions it ever again. For all we know the MC still has the mirror and just forgets to use it like a ret*rd. Also, the author never said that only one resurrection item exists, so even if the mirror can only be used once the MC should still look for other similar items. But nope. When the demon elder died (one of the most important characters who helped out the MC on numerous occasions and cared deeply for him and is like a parent to the MC) the MC grieves for a bit and then that's it. No mention of any attempt to resurrect him or anything even though the MC has previously resurrected people who had their soul destroyed before (Huai Rou Mu Yu). Is this cheap drama or what? Once you bring the power of resurrection into a story, you can't just take it away. With a ridiculously OP item like the resurrection mirror the MC should not be afraid of anyone dying on him as he could just resurrect them whenever he wanted without any cost or limitations.

Another item mentioned is a token that allows INSTANT COMMUNICATION ACROSS MULTIPLE REALMS. He used it multiple times in the story early on to communicate with his sect in the demon realms and later on (past like chapter 1000 or so) it was NEVER MENTIONED EVER AGAIN. Even when his sect in the celestial realm was under attack and they really needed his help they just shrugged and was like "oh sh*t we're under attack guess we're f*cked now". They didn't even send a messenger to the MC or anything. It's like. Oh the MC isn't here? guess we're f*cked. yeah he's away and it would be really nice to have his help but... what? notifying him? that's crazy. what's a communication token? never heard of it. Even though the MC used it multiple times in the past WITH THE EXACT SAME SECT (the true demon sect). It's really f*cking s*upid how the author creates pointless drama by having all the characters suddenly forget about the existence of items that had been repeatedly used previously. Just really dumb.

There's another item that can INSTANTLY TELEPORT EVERYONE IN THE ENTIRE REALM TO THE ITEM'S CURRENT LOCATION. The MC only used it once and it was never mentioned ever again.

I could go on, but I think you get the point. There are so many different bullsh*t hax powers in the story that common sense logic no longer applies to it. In the story magic to instantly find a person's location NO MATTER WHERE HE IS is commonplace, with the result that hiding is no longer possible. There is magic that can read people's minds. There is magic that can tell you exactly what happened at a place, just like replaying a video. You can trace the residual magical energy left by a person to know exactly which sect he came from. With this kind of magic being abundant, common sense in our world no longer applies. Sneak attacks should not even be possible anymore and yet the MC somehow carries out multiple sneak attacks without using any special magic whatsoever and still manages to not get caught. It's just ridiculous.

This is not even the biggest problem.

The biggest problem is that the MC is rash and hot-headed. On multiple occasions he kills people even while knowing that it wasn't the best choice. For example in competitions, killing was forbidden but he kills people during competitions anyway and gets disqualified. Why didn't he just wait until the competition was over and then kill them? Because "hurr they want to kill me so I have to kill them no matter what I'm a moron and can't wait 2 minutes to kill them when it's safe have to kill them now no matter what". What a dumbass.

After his teacher got killed while protecting him, he immediately activates his treasure's power to go back to kill the person who caused his teacher's death even though it would place him in great danger. This is especially dumb because it had absolutely no benefit for him (nor his teacher) and it was purely to vent his rage, and it almost jeopardized his long term objectives. When you consider that the reason the MC died in his previous life was because he went to avenge Qing Er before fully scouting out the enemy's abilities then the actions he takes in this life are especially ridiculous. A lot of battles he fights later on, especially against Xian Ting (Celestial Court?), are like this:

1. New enemy appears before MC. MC has no idea what the enemy is capable of.

2. MC rushes at enemy blindly.

3. Enemy uses some bullsh*t power like reverse time and f*cks up the MC.

4. Suddenly some deus ex machina appears and saves MC's ass

5. MC gets into even more trouble because of this later on

This kind of thing happens repeatedly. It's like the MC just doesn't learn. How hard is it to first find out the enemy's abilities before attacking? Especially since later on MC has the OP-as-f*ck mind-reading ability which literally allows him to read anyone's memories he wants, remotely. He never ever uses this ability to find out about someone's abilities before fighting them. He only used it on people he captured, even though there's literally nothing preventing him from just using it offensively since it was used against him offensively to great effect.

I'm giving this a 4 because the world is imaginative and expansive and the harem was pretty cute. I think he tried to make it believable even though it isn't really. I mean he r*ped the fox girl and then she fell in love with him even though she swore to kill him at the time. That's just unbelievable to me. And the merchant girl who fell in love with him, that felt a bit forced as well, not to mention the sect elder. It was also never explained why Qing Er went through so much for him even 1191 chapters into the story. Maybe it would be explained later on but I just can't be bothered to read it at this point I'm falling asleep while reading.

I have to say that I was expecting a good moment when Su Yun make his enemies And fiance regret, but only to find a better flow of story and harem relations. Forget about his fiance, the way this Su Yun become like superhero who remain lowkey and consider weak actually using mask to become batman is really interesting. Not all his enemies has to die, especially when they know how to back out.

I also want to point out that the summary should tell reader that MC actually not wasting 15 years being useless drunkard. He is actually become a spirit doctor and demon array master. So after rebirth, he can now build strength. Guys this novel is not worse than TDG and any other rebirth novel.
