21st Century Necromancer

If it had been before he transformed into an Underworld Feather Angel and attained a Divine Body to ascend to demigod status, healing Keiko's father's spiritual damage would indeed have been a very troublesome matter for Chen Yu. It would have not only required a specially arranged ritual space but also a complex and tedious ceremony to repair the soul.

However, once Chen Yu became an Underworld Feather Angel with the might of a demigod, repairing a damaged soul became a simple matter.

As a demigod, Chen Yu might not have Divine Rank yet, and even acquiring Divine Power required the collection of faith through the Cat-People created by Xiao Lan and Audis for the conversion, but this still did not negate the fact that he was now a demigod with power that rivaled the deities, capable of using Divine Arts.

The so-called Divine Arts are the spells used by deities. Although, in essence, they are not fundamentally different from the spells used by ordinary mages and are just as susceptible to theoretical research and analysis to construct spell models, Divine Arts differ because they require Divine Power to cast, making the principles behind them completely different.

Even if a mage were to fully analyze a Divine Art and then cast it using Magic Power, the resulting effect would be starkly different because Divine Power contains faith. Its principle is to leverage reality through the spirit and will, whereas magic extracts energy, transforming its form to achieve different effects.

Thus, even the most powerful mage can only mimic Divine Arts with magic but cannot release Divine Arts with Magic Power.

Similarly, due to the unique nature of Divine Arts, they can achieve things that even from the perspective of magic could be considered miracles, such as the Resurrection Technique.

Necromancers also employ the Resurrection Technique, but necromancy can be explained in principle. After human death, cells do not die instantly; for a short period, cells and body parts maintain their physiological activity. With the right intervention, it is possible to bring a deceased person back to life.

This is also the principle behind modern medicine's efforts to resuscitate individuals with stopped hearts and lungs, reviving their heartbeat.

This method ultimately has its limits, though. Although modern medicine can make a stopped heart beat again, if the heart has stopped for too long and the organs have suffered irreversible necrosis due to prolonged lack of blood supply, it is impossible to bring the deceased back to life.

In contrast, a Necromancer's Resurrection Technique is relatively more potent as they can forcibly stuff the deceased's soul back and use magic to drive the body's organs, enabling them to function normally and bring back physiological activities, achieving the effect of rising from the dead.

But Divine Arts are different; they defy logic.

The resurrection of Divine Arts means twisting reality directly under the influence of Divine Power, converting death into life for the deceased, restoring them from a state of death to one of living.

For mages, they can analyze the spell model of the Divine Art of resurrection and understand the entire process of Divine Power release, but if you ask them to describe the process of transition from death to life for the deceased, that's impossible because there are no principles to explain it; Divine Arts directly distort and change reality.

Even if mages could observe the entire process, down to the changes in every organ and cell, they still could not do the same.

Because magic, after all, is the mages' understanding of the world and the entire Multiverse. Although different from science in foundation and principle, it also needs to follow the universe's basic laws and various rules. Just as magic can use Magic Power to keep an apple from falling to the ground and science can use air to do the same, both are within the rule of the universe and pose no problem.

But Divine Arts are different; they directly modify the rules concerning the apple itself to prevent it from falling, without needing anything else to hold it up.

Therefore, for Chen Yu now, all that he needs to heal Keiko's father's soul injury is a Divine Art for repairing the soul.

However, releasing a Divine Art might cause quite a commotion, and Chen Yu didn't want to cast spells directly in front of Keiko's mother lest he would have to clear her memory afterward, which would only add to his troubles.

Luckily, Keiko's father's condition had stabilized and he was in Chen Yu's own laboratory, so all he needed was an appropriate moment to resolve his issues and heal him.

Returning home from the Regenerative Medicine Research Laboratory and feeling content with its status, Chen Yu was also contemplating which topics should be researched in this laboratory.

After all, having such a large facility, although he had enough money to support its operation, leaving it idle would be a significant waste and not in line with his initial concept of setting up the research laboratory.

But there were so many things he could research, what would be the most appropriate?

Healing Potions? Although already considered a relatively successful product, these potions are, after all, no more than the low-effect Healing Potions from the Multiverse Universal Necromancy Spell Compendium. If he were to research deeply, he believed that there could be significant improvements and modifications to this potion.

And if Healing Potions could be included in the research scope, then his broad-spectrum anti-cancer agents could also be brought into this research laboratory.

Although the broad-spectrum anti-cancer agents are already very successful as cancer suppressants, they have not yet achieved Chen Yu's initial goal of becoming targeted drugs that cure all cancers. Therefore, Chen Yu still wanted to delve deeper into their research.

Beyond that, research on plant-based treatments and neural regeneration could also continue, as these both fell within the scope of Regenerative Medicine.

Even Jounouchi Hiromi's research on artificial wombs and blood, as well as his previous considerations on human enhancement studies, could all be conducted within this laboratory.

However, it was clearly not yet the time to bring out human enhancement research, and although the laboratory had started operating, many aspects were just beginning, and it had yet to become fully integrated and well-coordinated. Launching too many research topics at once would only dissipate their efforts.

So, after some consideration, Chen Yu decided to start with research on Healing Potions and plant-based treatments initially. As for the other topics, they would be expanded upon once the entire laboratory was well-coordinated and all research personnel could operate collaboratively.
