The foremost problematic requirement was REALLY COMPLEX TRACKING MAGIC, which is still a hassle even with MC's Eye of Gluttony; While the latter is an issue if its a really valuable or VERY NEEDED ITEM at the later floors.

Yi Zaha is the MC of The Return of the Crazy Demon. Master Gu was born a villain after all, being strong is a naturally gifted necessity to become the stepping stone or counterpart of heroes. The regression or reincarnated part is still debatable, but the transmigration is guaranteed at least.

If he empathize others, he wouldn't be baiting and challenging the constellations of their authority, much more using people and characters alike to his whims since the beginning. Just because he knows the story and spoilers, doesn't mean he can toy with it. He repeated Kang Jinhyuk's (Solo Max Level Newbie's MC) mistake more often than you knew. Kim Dokja changed the course of events, yes, but his thinking of having things are still in control is one of his greatest mistakes, much less not thinking things from his mom's POV.

Nope, you remembered the wrong manhwa. Yi Zaha was no cultivator, but a martial artist, and he was never imprisoned.

Yes, Master Gu was the fated villain, but originally as a stepping stone for the first emcee. Just reread Chapter 1 and you'll see the plot armor so clearly and the logical ways Master Gu used to defeat him right off the start. And Master Gu's status as a reincarnator, regressor or transmigrator is a tad hard to explain... but to put it overall, Master Gu is both a regressor (having a future foreseeable event) and a transmigrator (system guidance, plus his knowledge and wariness of plot armor). Regardless of his status, yes, Master Gu is without a doubt, an UNDENIABLY TERRIBLE EVIL who wears justice and righteousess as a mask for appearances and deception.

I didn't say natural good don't use manipulation. That's one of their differences, natural good people can and will resort to manipulation if it means for the good of many, while natural justice people are pretty much moral strict people to not accept inhumane, much less immoral acts as it'll mean that their justice is one-sided - which completely defeats the purpose of justice itself.

While most evil people are separated between those who are either means-oriented or result-oriented. Take Yi Zaha's philosophy (The Return of the Crazy Demon's MC) for example, he knows he's a crazy demon himself for killing people (a villain for conducting immoral actions), but he's also aware that he's slightly better than most if not some others for not killing innocents (fighting fire with fire, being evil to kill evil). This makes Yi Zaha either a technically natural good hero, or a literal means-oriented villain.

And Master Gu is obviously a result-oriented villain, as we have already witnessed up to now.

And that's my point, these emcees have the power, but spineless to fight for it or making it being worthy of themselves - unlike Master Gu with the ultimate GAME (Goals, Agenda, Morals and Ethics) to shape and shift things to his bidding and will.

Then your perspective for natural justice was different from mine. From what I see, Master Gu is a true villain that manipulates people by thoughts, backed with sufficient power to back his own words (remember that Master Gu was supposed to be a cannon fodder villain at the very beginning, but won over his predestined demise due to the consequential logic in play).

Natural justice to me, is someone who is like Master Gu but without manipulation. Someone who naturally wins over hearts and reputation via their own actions and deeds (sort of like Master Gu still), except that Master Gu did so just to become to ideal of people's eyes for his own use, while a true person of justice should expect nothing in return, only did so out of the goodwill of their own.

There was natural justice that met Master Gu - his regressed fiancee and cousin, both resolved by logic. We're yet to see a true hero out of those emcees so far, only rotten, spoiled brats who abuses plot armor. Although that Qin Wu Ya is quite the exception, just failed in the essence of timing.

Yes, there's balance in this world, but read my words - these emcees have DONE NOTHING deserving that fortune. They had the backings, resources and talent, but did nothing to improve themselves and just spamming treasures at Master Gu - IS THAT REALLY ALL THERE IS OF FORTUNE'S CHOSEN?

Welp, there goes the ignorant, spoiled king. No RIPs for you.

Heaven's punishment? Oh please, you emcees didn't even do a single thing deserving of heaven's favor (all the plot armor given to them). The heavens should be ASHAMED of you loser emcees instead of punishing Master Gu.

At least the three eyed dude finally grew some brain cells, buying time allowing the smarter one to flee. But not in the right dirrection (thinking process)... they'll die like rats for real.

I only finished watching Season 1 of its anime, and yes, the regression did broke the MC's mind several times, at least 5 times.

Don't spoil. XD

Wait, what? But hold it right there, don't spoil me. Let me enjoy this manhua over time.

Re:Zero also has emphasis on the curse of regression part. Mushoku Tensei itself has no time shenanigans either, just reincarnated life with past mentality, and the story develops both the MC's character and mentality.

Yup, like I said in the previous chapter, these ignorant emcees are too f*cking prideful to do that, and that will only result in deeper graves for them to bury in.

Indeed. Its fair to assume that the Empire was once indirectly under Alice's command via the first Reinhardt, since Alice was a resident of a way higher floor than the Empire.

Master Gu's memory recovery and true identity ain't much of a spoiler by now, but the timing is. XD

Because who cares about the future when you can shape it in the present? This is where the emcees are ignorant of.

Hah, I sort of expected this. Master Gu will let his allies or enemies knew his identity under two circumstances:
1. Guaranteed loyalty (happened to his fiancee).
2. Absolutely dying soon (happened to most brainless, brainrot and ignorant emcees).
