Once, I wanted to be a good person

The first surprise Fang Ze discovered was actually the main purpose of his experiment this time:

He could transform into a Divine Fiend! And after transforming into a Divine Fiend, he wouldn't lose his sanity and had almost no debuffs.

To be honest, this was actually different from Fang Ze's previous suspicions: he always suspected that the reason Divine Fiends didn't resign was due to soul damage, and the transformation in Demigd Prison also started from the soul level simulation, so once he transformed into a Divine Fiend, he was likely in a state of soul damage.

If that's the case, his mind might be affected too!

Therefore, before conducting the experiment, he hesitated for a long time and made many safety measures: like having the Flower God guard by his side and placing most of his thoughts in his body in the Real World.

This way, even if something unexpected happens, he would have the chance to remedy it.

As a result, when he transformed, he found that nothing happened. The entire transformation was as smooth as transforming into a Demigod.

This not only allowed Fang Ze to finally reassure himself to squeeze Dahei Jialuo dry into a Divine Fiend, but also made Fang Ze discover a major secret of the Divine Fiend: that is, the soul of a Divine Fiend is likely complete.

And based on this discovery, Fang Ze continued his research and experimentation, and soon discovered a second surprise:

Since the soul of the Divine Fiend is complete, they actually possess Spiritual Wisdom and can understand language.

This also explains why, in the initial experiments, Divine Fiends could execute some simple commands and could use body language to answer Fang Ze's questions.

However, in specific research, Fang Ze also found that although Divine Fiends have spiritual wisdom, it is intermittent.

Possibly because they've exhausted their lifespan, they are continually eroded by time. So, they cannot maintain this "lucid state" for long.

To put it plainly, Divine Fiends are like goldfish: they have a few seconds of sanity, quickly forget everything, and revert to a beast-like state. Afterward, they gain a few more seconds of sanity, then revert to a beast again.

However, this simple spiritual wisdom is already sufficient for Fang Ze. Because he can use this wisdom to arrange for Divine Fiends to do many things.

For instance, Fang Ze can have them use the method of Demigods to actively absorb the Power of Laws, recover their wounds and Divine Power, and completely overcome the biggest drawback of Divine Fiends.

For example... Fang Ze can break down the method of connecting to the Demigod secret realm into several simple steps, allowing the Divine Fiends to perform the operations step by step, completing this complex task successfully!

These will greatly improve the usability of Divine Fiends.

Continuing research in this direction, Fang Ze also discovered a third surprise, which was a bold conjecture of his.

That is... since the soul of Divine Fiends is complete and they possess the most elementary spiritual wisdom, then essentially, they truly have no difference from Demigods.

And the reason why they became beasts that can only act by instinct is completely because they no longer have lifespan protection and are constantly disturbed by time. Moreover, because they lack sanity, they can't voluntarily enter a dormant state to supplement their lifespan.

So, if Fang Ze uses the life threat from the Holy Reformation Room to guide Divine Fiends into a dormant state, will their lifespan be replenished? Thus, resisting the erosion of time and "returning to being Demigods"?

Furthermore, Fang Ze thought even more: a person is "this person" because of multiple factors comprising memory and personality.

And for such reborn Demigods, their memories and personalities have long been erased by time; they are like newborn children, ignorant of everything, requiring re-learning.

Then... is this new life still the original Demigod?

And if Fang Ze instilled thoughts of loyalty to him and fighting for him "from childhood," would they become the most loyal Demigod warriors for Fang Ze!?

Though 12 Divine Fiend Death Warriors are indeed decent, if some of them are spiritually wise Demigod confidants, Fang Ze believes they would be more effective for him and capable of executing more complex tasks.

Thinking this way, Fang Ze secretly decided that once the current crisis was over, he would definitely select a Divine Fiend to cultivate and see how it goes.

Standing silently in the Late-Night Investigation Room, after mentally sorting all his research on Divine Fiends, Fang Ze came back to his senses.

He put away his notebook and temporarily set aside the Fiend Codex, allowing this Divine Fiend to recover its Divine Power. Meanwhile, he planned to check tonight's findings.

Today was Fang Ze's first investigation of this creature Divine Fiend. According to the normal "pattern" of the Late-Night Investigation Room's yields, Fang Ze deemed that something good should come of it.

Two minutes later...

"Bad luck!" He muttered a complaint as he casually put the acquired item into his Space Folding Bag.

Possibly because Divine Fiends practically had no intelligence or thoughts, all Fang Ze's experimental and investigative gains were summarized and deduced by himself, rather than informed by the Divine Fiend. Therefore, this investigation's yield was quite mediocre, just an ordinary Extraordinary Artifact.
