After conducting experiments, Fulen successfully confirmed that if other items were to pass through the paper with the Door drawn on it, the spiritual energy consumed was indeed higher than that required for his body to pass through.
Moreover, after more precise experiments, Fulen confirmed that for items of the same weight, clothing required less spiritual energy to pass through than other items.
Later, Fulen tried again with items of the same volume and clothing of the same volume, and the results were the same.
Fulen confirmed that for items closer to himself, the spiritual energy consumed for passage was less than for items never touched, even inorganic ones.
As for other people's bodies, although Fulen had not confirmed it, it might consume more spiritual energy.
Based on these simple experiments, Fulen made a deduction, the Apprentice requires less spiritual energy to transport items closely related to himself than to transport items not closely related to himself.
Although "Open the Door" has no offensive power, it does not prevent Fulen from developing it into an attack method.
The most important tool required for this is the note that has been passed down in Fulen's family.
After searching his home for a while, Fulen successfully found a very sharp dagger.
The hilt of this dagger was black, and its oval shape greatly reduced the dagger's volume.
The blade, which seemed to exude a chilling aura, indicated that this dagger was not a mere plaything.
It is said that this dagger was a practice piece made by an Artisan using meteor iron and some extraordinary materials.
This dagger had no Beyonder abilities; its blade was simply very hard and extremely sharp, and it required no maintenance.
Even when Fulen found it now, it was still as sharp as new.
This dagger was the only thing in Fulen's family that could be considered an offensive extraordinary materials.
When Fulen was young, he often saw his father, Martin Freeman, constantly fiddling with it.
Of course, after Fulen grew up, the person who often fiddled with this dagger became Fulen.
Fulen placed this item, which could barely be called an extraordinary materials, into its sheath, and then, along with the entire dagger, put it into the inner layer of his close-fitting upper clothing, feeling the cold against his skin.
What made Fulen feel fortunate was that although current clothing was generally tight-fitting, making people feel light and agile, for Fulen, his favorite clothes were still looser ones.
Therefore, placing a dagger under his upper clothing did not cause the dagger to protrude at all.
After Fulen enveloped the dagger with his spiritual energy a few times, his head suddenly felt as if it was being continuously struck by a giant hammer.
Voices, he knew not from where, echoed in his ears, whether whispers or roars.
When not listening intently, they seemed like whispers, like being bothered by mosquitoes, making one Can't help it want to listen closely to where the annoying sounds came from.
If he listened carefully, he would find that those voices suddenly grew louder, as if trying to convey something that could destroy him into his mind.
It felt as if a thousand needles were pricking Fulen's head.
Fulen felt like he had stayed up for three days and three nights playing games without closing his eyes, only to realize he had to go to class, with the teacher constantly staring at him, making him dare not sleep.
That feeling of dizziness and nausea, with no outlet, drove Fulen mad.
Forcing down the urge to go crazy, Fulen staggered into the bedroom, somehow ending up on the bed.
He then assumed a meditation posture, gradually reining in his thoughts.
Finally, Fulen fell asleep without knowing anything.
The next day, Fulen woke up in a daze and saw his clothes were very messy.
Fortunately, even in his muddled state yesterday, Fulen did not forget to firmly insert the dagger into its sheath, so it did not kill Fulen while he was sleeping.
However, now this dagger was pressing against Fulen, causing him great pain.
After placing the dagger on the desk in his bedroom, Fulen painfully rubbed the red, almost bruised mark on his stomach, deeply remembering this lesson: never completely deplete your spiritual energy, especially now that Fulen's digestion of his Beyonder potion has not yet taken effect.
After quickly washing his face and brushing his teeth, Fulen sat down at the desk in his bedroom again.
On the desk was a beautiful calendar with July 6th circled.
Fulen was certain he had never circled this date, but at the moment, he didn't understand what the circle meant.
After thinking for a moment, Fulen decided to go to the secret chamber in the study to look for tomorrow's astrological signs.
If Fulen's guess was true, then it was fortunate that his crossing happened yesterday; if it were today, he might die today.
After opening the seemingly ordinary surface of the study, Fulen saw books that could fill three or four shelves neatly arranged in this mysterious bookshelf.
After thinking for a moment, Fulen took out a book from the upper left corner.
This was a black notebook, entirely handwritten, with quite elegant handwriting.
Opening the flyleaf, Fulen saw the Author of the notebook and the message left behind: Martin Abraham's Astrological Diary, a gift for my dearest son, Fulen.
Fulen suddenly recalled the father and son from his memories, a bond that always brought warmth whenever he thought of it.
His father was an amateur Author with a distinct scholarly air and a Lawyer by profession, and the child was determined to pull the Abraham Family out of the Abyss and become as powerful as his ancestor, Bethel Abraham.
In Fulen's bedtime stories, Fulen always wished Martin would tell him about the glorious history of the Abraham Family in the fourth epoch.
Although Martin was unwilling for Fulen to experience the pain of his own experiences after becoming a Beyonder, he was still willing to help his child ward off predictable dangers, the predictable full moon day each year.
For his child's naive dream, Martin, who had long only perfunctorily played the role of an "Astrologer," changed his routine.
He began to observe the celestial phenomena every night and continuously read various astrological books.
Unfortunately, great fatherly love is insignificant in the mysterious world.
Just after Martin had calculated the full moons for five or six years, Martin, who had completely digested the Astrologer potion, turned his attention to the annual Blood Moon.
After completing the deductions for the dates of the Blood Moon for these years and marking all the dates at the back of the notebook, tragedy struck.
On a silent night, Martin strangled himself to death.
It can be confirmed that this matter was definitely related to a certain Outer Deity, because the Blood Moon is caused by the Primordial Moon.
Fulen only dared to view himself from an outsider's perspective, not daring to recall any information related to this Outer Deity, because merely thinking about her would lead to infection, and hatred would only render his father's sacrifice meaningless.
Unfortunately, Fulen, the child raised solely by his father, could only gradually sink into despair, alternating between cherishing his father's kindness and hating himself, becoming the recluse he is now, isolated from the world for four or five years.
Although Fulen did not empathize, he still felt sad about the destruction of something beautiful, but he could only think of his own life and dared not complain or imagine anything.
