They won the Holy Grail War, but this turned out to be the Virtual Tree Universe.

Preliminary Report on the Combat Strength of the Pillars and Demons (Chapter 12)
The sunrise viewing experience for Danlei, Tanjiro, and Tomioka Giyu went smoothly.

Tanjiro and Giyu Tomioka listened to Danlei's account of the outside world the whole time, while Danlei simply repackaged the magic world of Type-Moon and told it to the two of them as a story.

Since almost all of these stories are true, Tanjiro couldn't detect that Danlei was lying. Tomioka Giyu even said that if he ever had the chance to retire in the future, he would definitely want to travel abroad.

Finally, the deer that Dan Lei had captured to draw blood for the Heroic Spirit Summoning Circle was not wasted. Dan Lei had Sasaki Kojiro take it to the mountaintop, where it became the three's breakfast.

Bathed in the glow of the rising sun, Giyu Tomioka completely lowered his guard against Tanjiro, who was basking in the sunlight. Before leaving, he pulled out a piece of bamboo from somewhere, made it into a gag, and gave it to Tanjiro, telling him to use it to gag Nezuko so that she wouldn't suddenly bite someone.

Of course, given the strength of bamboo, if Nezuko really wanted to bite someone, she could crush it in one bite. To be honest, this thing is more for show than for real.

After giving the gift, Giyu Tomioka took his leave. As a Pillar, he was quite busy, and he needed to write a report about his experience with Danri to tell his teacher and the Demon Slayer Corps' leader.

After parting ways with Giyu Tomioka, Danri and Kojiro Sasaki followed Tanjiro to Mount Sagiri.

Because it was the Taisho era, Danlei only had a slight understanding of the land beneath his feet, and knew a little about the place names.

As for how to get from the mountain where Tanjiro's family lives to Mount Sagiri, Dan Lei said that he really couldn't understand the maps of that period, which looked like scribbles, and that Sasaki Kojiro was better at finding his way than him.

Therefore, Tanjiro led the way the whole way.

Just as Dan Lei had predicted, there were very few things in this land that could be used for cultivation through the earth's veins, but ghosts were born with the ability to absorb the magic power of the earth's veins.

After several days of observation, Dan Lei confirmed that even when Nezuko was not asleep, she could slowly absorb magical energy from the ley lines to replenish herself simply by standing there.

Sleeping can accelerate the absorption of ley line magic.

Therefore, by hardly exercising, she was able to balance the energy deficit in her body and suppress her urge to eat during the early stages of becoming a demon.

After all, the reason why ghosts love to eat people is because the magic contained in human flesh and blood is abundant in rare creatures such as mythical beasts and magical beasts.

Human blood is the easiest and best magical medium to find, which is basic common sense. Many cult magical rituals explicitly state that human blood is the best material for drawing the ritual site.

Humans' instinct to eat is ingrained in their DNA, so when a demon's body lacks energy, it will naturally want to eat, and human flesh and blood containing magical power are the best food.

As for feeling disgusted by ordinary food after becoming a ghost, it's probably the same reason why people who are used to eating strong-flavored food find bland food extremely tasteless and unpalatable.

Normally, food processing will destroy even ingredients that originally contained magic power due to high temperatures. Without the magic power of seasoning, it would taste like chewing wax to ghosts.

Those ghosts who rely on food to replenish their magic power will naturally lose their ability to absorb the magic power of the earth veins to maintain their vitality due to lack of exercise, which is why Dan Lei felt that the earth vein energy in this place was unusually rich.

However, the above conclusions were drawn by Dan Lei based on the demon Nezuko, and lacked a control experiment, so their correctness is still debatable.

Of course, in his spare time, Dan Lei also used telepathy to align the granularity with Sasaki Kojiro, estimating what level a Pillar like Tomioka Giyu would be among the Heroic Spirits.

Okay, it's probably better not to put Giyu Tomioka's combat power into the Heroic Spirit category. According to Koji Sasaki, if his attributes were placed in the Heroic Spirit category, his Luck would be unclear, Strength and Speed ​​might be D, and the rest would most likely be E.

This combat power isn't weak among magicians, but among Heroic Spirits, it's probably only enough to fight one of the Hundred Faces' largest clones.

Of course, this refers to the Hundred-Faced Clone not using poison and engaging in direct combat. From this perspective, the Lower Moon demons, whose fighting power is roughly equal to, or even slightly inferior to, ordinary Pillars, should also be at this level.

You asked what level Danlei is at among the Heroic Spirits right now?
Danlei will tell you that your strength and agility are around E+ (using enhancement magic can greatly increase these two attributes); your endurance will most likely reach C with the blessing of Abundant Fate; your magic power in the Demon Slayer environment should be at least B; and if you're lucky, you'll be able to travel through time, so it must be A.

However, despite Dan Lei's high stats, he might not be able to beat Tomioka Giyuu in close combat. This is due to the difference in skill. After all, Dan Lei has a lot of magical power, but he doesn't know many magic tricks specifically for combat, and his martial arts level is very average. In a fight, he can only beat up weak opponents.

But as a support and healer, Danlei is absolutely professional. She hasn't forgotten the medical knowledge Danzhu taught her, and her ability to heal people in the Abundant Destiny is also unparalleled. Moreover, Danlei can also make dolls to provide assistance.

Ultimately, the strength of demons lies in their Blood Demon Art, which is often unreasonable. Even if a Pillar encounters a particularly nasty Blood Demon Art, there's still a chance of them being defeated.

This ghost is stronger than the Dead Apostle. When the Dead Apostle is low level, you have to analyze the specific situation to compare its combat strength with that of a zombie. If you want to have talent spells, you can only get them by becoming a high-level Dead Apostle.

But it seems that the demon's demonic powers will naturally awaken if it consumes a few more human blood.

Considering that Nezuko can awaken Blood Demon Art even without eating people, Dan Lei analyzed this thing and felt that it might be a kind of ley line blessing.

The idea that evil spirits are actually a species blessed by the earth's veins is too hellish, so Dan Lei just silently noted it down, preparing to find a way to verify it later.

After several days of traveling day and night, Dan Lei and his group finally arrived at the foot of Xiaowu Mountain, and Dan Lei's first control subject was found.

It was the same temple from the anime, but this time, before Tanjiro even got close, Danlei used magic to hear disgusting chewing sounds inside.

Since there were no living people inside, in order to let Tanjiro see with his own eyes that demons eat people and realize how terrifying these monsters are, Danri did not stop Tanjiro from approaching and opening the temple door.

Upon witnessing the hellish scene once again, Tanjiro was indeed stunned.

However, Dan Lei intervened when the ghost lunged at him.

We'll still use magic threads. These are the foundation of puppetry, and Danlei is most skilled at using them. Moreover, ordinary ghosts who don't even know blood demon magic are too weak to break free from the magic threads' restraints.

So, the ghost was frozen in time, suspended in mid-air by the magic threads in a pouncing pose.

Then, Danlei pushed aside Tanjiro, who was blocking the doorway, and looked at the demons inside, laughing.

"Alright, the damned experimental tool has been captured. Now it's time for some fun experiments."

Tanjiro, go dig a few holes behind the temple and bury these corpses. My experiments here are going to be quite gory, so it's best if you don't watch.

　All I can say is that the original concept of Fate's Servants being able to completely crush Mages is now completely irrelevant.

　　Leaving aside beings like the True Ancestor, there are already several magicians whose combat power rivals that of Heroic Spirits.

　　Furthermore, Medea was completely crushed by Rin in the UBW route using close combat.
