After chatting for a while and having something to eat, Han Li and Dugu Bo each left and headed to the adjacent rooms.
The nights in the City of Slaughter are not safe. To put it bluntly, they are even more dangerous than the days.
In just one night, Han Li and Dugu Bo killed no fewer than ten people, even though Han Li had already displayed his strength during the day.
Poisoning and sneak attacks are just basic methods.
Yes, in the tunnel under the courtyard that Han Li had previously noticed, he encountered the previous owner of the house.
This time, he showed no mercy and decisively sent him to meet Asura.
By the time the sky over the City of Slaughter turned gray again, signaling daytime, there were already fourteen corpses hanging outside the courtyard walls.
At around what would be equivalent to nine o'clock outside, a team of black-armored guards came over, skillfully took away the corpses, and cleaned the courtyard walls.
This made Han Li marvel at their professionalism, reminiscent of scenes from Hong Kong movies he had seen before.
In these few days, he sent off quite a few people. Once or twice might not matter.
In a week, they were attacked an average of twice a day. Of course, in the last two days, no one dared to attack them casually anymore; most of the attacks were concentrated in the first three days.
Later on, upon discovering enemies, the three women even actively applied to fight, with others supporting them, integrating into the City of Slaughter.
Han Li remained steadfast, participating in the Hell Slaughter Arena's competition once a day, experiencing that peculiar energy most directly.
To say it was peaceful would be inaccurate. Compared to the constant slaughter visible throughout the city, their lives were relatively decent.
The remaining time was spent cooperating with the plane consciousness, making various attempts.
After half a month, Han Li finally obtained what he wanted and excitedly gathered everyone together.
"The feedback energy obtained after killing here?"
Dugu Bo looked down for a while, then raised his head to look at Han Li, somewhat surprised: "Is this a new soul power circulation route?"
"No, it's not a soul power circulation route. To be precise, it's a method for mobilizing killing intent."
"For the time being, try to suppress the purification energy. After you get the hang of the cultivation, try to release it."
But because Han Li had modified the rule proportions on them, he still vaguely sensed a bit of it. However, that energy is still a bit weak for him now and can be ignored.
Dugu Bo nodded thoughtfully.
Han Li divided the paper in his hand into several parts and handed them to everyone.
"At other times, you can also actively initiate cultivation, but do not exceed one hour a day."
Dugu Bo nodded in agreement.
Han Li thought of the purification power of Dugu Bo and reminded him.
"When you feel the energy, run this technique, prioritizing its guidance into the external soul bone, ensuring the purity of your soul power. After it passes through the soul bone, use it to enhance yourself."
"In the coming time, we will appropriately speed up the pace of combat. You can take this opportunity to familiarize yourselves with this technique."
Han Li's expression became serious.
Han Li looked at the three women and solemnly reminded them that this was the best temporary solution he could think of.
Everyone nodded and seriously memorized the energy circulation route on the blueprint.
Indeed, the current four-member team all possess their external soul bones.
Shui Bing'er obtained her external soul bone when she acquired her third soul ring. It was a pair of wings, similar in effect to Han Li's first soul ring, enhancing her affinity and perception of ice elements.
As for Xiu'er, when she went to obtain her fourth soul ring, she found a pair of soul bones in the lair of the soul beast. They were highly incomplete but were the claw bones of a Dark Gold Terror Claw Bear.
Under Han Li's decision, she directly absorbed them, relying on her martial soul and foundation to forcefully evolve the incomplete soul bones into palm bones. However, the age was relatively low and needed slow growth.
But considering the characteristics of soul beasts, age wasn't that important at this point.
Seeing everyone start to memorize, Han Li stepped aside and sat down, lost in thought.
He named this method the Blood Fiend Art.
To be precise, this technique is not for cultivating soul power; rather, it is more inclined towards a spiritual power cultivation method. Of course, it is a limited version, exclusive to the City of Slaughter.
As Tang San said, the City of Slaughter is poisonous, but this poison does not target the body. It is more like a mental toxin.
The main reason for the formation of the toxin is the remnants left by the Asura God and Rakshasa God. Even though the divine power has been diluted countless times, it still actively disperses.
This is their rule power, inherently inclined towards negativity.
As for why Bloody Mary can detoxify, aside from its special composition, it is also influenced by rules.
The energy feedback formed after killing in the City of Slaughter, or rather the energy collected by the City of Slaughter itself, is essentially a collection of life and soul energy, which is beneficial to humans.
But the killing intent and weak divine power mixed in are another matter. However, considering this is part of the assessment itself, it can be understood.
After all, the energy source is the people here, and even though the City of Slaughter undergoes some conversion, it does not intercept the energy within.
Which antivirus software would automatically block its own company's ads? It's almost the same concept.
The Blood Fiend Art is essentially a patch created by Han Li and the plane consciousness.
After the initial screening, the Blood Fiend Art is used for secondary decomposition, redistributing the energy: life energy to the body, and soul power to spiritual power.
Then, it is channeled into the external soul bone, forming a fixed brand. After intercepting the killing intent and weak divine power, the killing intent is used to stimulate spiritual power growth inversely.
However, the issue is that the energy is still partially retained by the external soul bone for its enhancement, with a bias towards life energy. Hence, Han Li's positioning of it is more inclined towards a spiritual power cultivation method.
It can also be used for daily cultivation but mainly absorbs some scattered killing intent. In the City of Slaughter, the effect is still quite obvious, but outside, without the continuous support of killing intent, the effect will naturally weaken.
This is also the current limit of what Han Li and the plane consciousness can achieve. Compared to the most obvious and exposed killing intent, the power of other emotions is still beyond Han Li's current capabilities to utilize.
At this moment, Han Li was contemplating an issue. The success of the Blood Fiend Art made him see another possibility.
That is, whether he could use the special nature of this place to mass-produce soul masters.
In the past few days, he has also figured out the situation here, and it is somewhat different from what was recorded by the Spirit Hall.
Not only soul masters come here; of course, those who actively come in are naturally not good people.
He learned that some people were just ordinary individuals before entering, but they became soul masters thanks to the special nature of this place. There is even a leader of a small group who started from scratch and rose to the top.
The City of Slaughter is indeed a treasure trove. The energy feedback after killing, although mostly absorbed by the city, or rather this place of inheritance, also truly feeds the remaining energy back to the killer.
If the rules within can be understood and utilized, although it is a very evil method, it is indeed effective.
The mixture of life energy and spiritual energy replenishes one's essence and feeds back into the spirit, which is essentially what a soul master is.
Moreover, due to the influence of gods, this place is considered their domain, breaking the limitation of soul rings. The increase in soul power does not require hunting soul rings, which might be the true cultivation system of the Douluo Continent.
Han Li took a deep breath. Coming here, he indeed gained more than just superficial things.
And these things will be his next goal. He doesn't need to understand the reasons immediately, but it will be his future direction and the problem he needs to solve.
For now, the mass production of soul masters can be put on hold. According to the rules here, it is a bit too bloody. Understanding the principles and then improving them might be the best approach.
Yes, Bloody Mary cannot be overlooked. Although they don't need to drink this stuff, for Han Li and his group, it is equivalent to cultivation resources.
Spiritual energy can be actively cultivated and supplemented by the killing intent in the city, but the life energy intercepted by the spirit bone can only be compensated by these people. The cultivation of soul power must not be neglected; otherwise, it would be putting the cart before the horse.
After leaving, it would also be time to meet Tang San.
Han Li silently decided in his heart. In the City of Slaughter, just asking for Bloody Mary without directly killing you is already very merciful.
Indeed, the God of Asura is also ruthless, understanding the principles of sustainable development. I'm just doing what the God of Asura would do.
In the next three months, Han Li and his group maintained the same lifestyle as they did in the Spirit Hall.
The difference is, in the Spirit Hall, they were cultivating, practicing actual combat, and resting. Here, they are cultivating, killing, collecting protection fees (Bloody Mary), and resting.
Under the influence of the Blood Fiend Art, everyone could feel their progress, and the killing intent was still controllable.
Of course, when facing others, they would actively stimulate the killing intent, appearing more frenzied, and even the atmosphere in the City of Slaughter began to change, with much less mutual killing.
A storm is brewing; this is the current state of the City of Slaughter.
In the Divine Realm, the few gods of the Divine Realm Committee were observing Han Li and his group's actions.
Asura went from initial surprise to gradually becoming calm, with a thoughtful look in his eyes.
This situation made Destruction feel uncomfortable. Although he had no opinion on Han Li and his group, Asura's reaction made his intentional observation to catch faults seem somewhat ridiculous.
