"It seems I need to have Miko and Mai go to these places during the upcoming period."
Rosen said, stroking his chin.
The Malevolent Spirits inside the Shadowlands are clearly stronger than those wandering the streets. If he sends them there, they can eliminate hidden dangers while also improving themselves.
As for Rosen himself, there was only one thing he needed to do.
That was to quickly establish a place that could automatically absorb the Souls of the deceased, preventing people from becoming spirits that wander the earth after death, either vanishing over time or becoming Malevolent Spirits.
However, since Yotsuya Miko and the others were currently dealing with the Malevolent Spirits in the amusement park, he only needed to tell them afterward.
As for how to establish it.
After pondering deeply for a while, Rosen realized that he could modify his own Divine Kingdom.
After all, his Divine Kingdom could inherently absorb Souls; however, it couldn't contain them autonomously, and currently, he had to control it manually.
If modified, he could contain all the Undead in Tokyo, or even the entire Island Nation, in a short time. But then there would be no Malevolent Spirits left for the girls to practice on and level up.
Although it would be a permanent solution, Rosen's main goal was still to allow the girls to grow individually.
As for the spread of the Shadowlands, Rosen can solve it by himself.
Therefore, his idea is that as long as he can establish a Divine Kingdom that can absorb the Souls of the deceased, it will be fine.
As for the evil spirits that already exist in the world, Rosen does not intend to manage them.
As for whether the remaining number of evil spirits is enough for the girls to upgrade, Rosen doesn't think it needs to be worried about.
After all, living beings die every moment in this world. Not to mention thousands of years from ancient times to the present, because Rosen could tell from the scattered words of Taisui Xingjun and the Soul-Snatchers before their deaths that gods existed in this world a long time ago.
But for some unknown reason, the gods suddenly disappeared, and even the road to the land of the dead was completely sealed off.
This led to the dead having nowhere to go after death.
They either disappear or forget their past lives and become evil spirits.
Rosen has no clue for now, so investigating the truth can be postponed.
Establishing a self-sustaining Divine Kingdom is the top priority.
Thinking of this, Rosen suddenly felt that he had entered a misunderstanding.
Why should he think from scratch?
Doesn't he have ready-made experts?
The so-called expert is the God of the Bible.
Last time, Rosen obtained the God-Slaying Artifacts, Twilight Healing, through the chat group lottery.
Now, that Holy Spear is hanging in his house as an ornament, and the will of the God of the Bible within it is being nourished by the Divine Power of the tree of life to restore consciousness.
Although her power cannot temporarily recover to its Peak, she at least knows how to establish Heaven and Hell.
Rosen quickly took out the 'Victory' quanta.
Like a crystal ball, golden light enveloped it, and a delicate girl like a doll was curled up inside, sleeping.
Seemingly sensing Rosen's aura, the sleeping girl slowly opened her eyes and woke up.
Opening her hazy sleepy eyes, the Bible Loligoddess confirmed it was Rosen, then flew out of this quanta and simultaneously returned to her normal size.
"Master, are you looking for me?"
"Yes, I want to ask you how you built Heaven and Hell in the DXD World, and how the Souls of the dead went to those two places by themselves."
"Master, do you want to establish your own Heaven and Hell?"
Rosen did not deny it.
"The construction of Heaven and Hell is not difficult. You just need to choose an alternate dimension attached to reality and then use divine arts to build the corresponding realms. However, the most important thing is their functions. Since it is a place to receive the dead, corresponding rules need to be established."
"Master, you should know the principle that one plus one equals two, right?"
Hearing this, Rosen looked at her expressionlessly.
One plus one equals two, even kindergarteners know this.
"I'm just giving an example. One plus one equals two is a rule that will never change. After realizing this, I used the tree of life as the cornerstone to create an existence called the System. It can access the essence of the world and create corresponding rules."
The Bible Loligoddess said word by word.
"Create?"
Rosen raised an eyebrow.
Yin Lingni Ba Si Qi Si Wu Lu ". So it cannot be changed?"
"Yes, although I successfully created the System, I can only add my own rules, and the added rules cannot conflict with the existing world rules. Otherwise, they will either be impossible to implement or will lead to the disorder, or even collapse, of the world's rules."
The Bible Loligoddess nodded.
"So, under this premise, I can only add some rules that do not affect the original world, such as what you said about receiving the dead, or the prayers of earthly believers, Divine Artifacts, and so on."
Rosen roughly understood the operating method of the System.
The "System" created by the God of the Bible is like a new function.
And the entire world is another large System. The God of the Bible created a small System that connects to the large System. Its various functions are realized by different codes. Once a conflict occurs, it will lead to errors or even crashes.
Regarding this, Rosen knew that after the death of the God of the Bible, the first problem to arise was the Divine Artifact System.
Originally, Divine Artifacts could only be Awakened in pure human Bloodline.
But after her death, due to lack of maintenance, the System malfunctioned, allowing other races that were not human to also Awaken Divine Artifacts and even God-Slaying Artifactss.
Furthermore, originally, Holy Power could only be used to heal humans, gods, or angels.
However, Aisia, the Saintess of the Church in the original work, could use the Divine Artifact "Mothers Smile" to heal demons.
Michael discovered this error. In order not to let the System crash, he could only use the plot where Aisia was framed to expel her from the Church.
"In that case, I want to create a System that can be inserted into this world. You help me."
Rosen said.
