Currently, Ling Yi possesses over ten thousand demonic Demon Spirit.
Tens of thousands of demon Demon Spirit from the Demonic Void Realm are enough to Guard the border, after all, the Demon Person have not yet evolved into the Devil Clan.
Every day, 60 Demon Spirit return to Dafeng City, where Ling Yi devours 80% of their Demonic Yuan before returning to the border.
The reason why the number of Demon Spirit increased so much in a short period of time is that Ling Yi taught Demon Spirit Art to some of Demon Spirit.
Now that the Demon Spirit has learned Demon Spirit Art, will it break free from Ling Yi's control and betray him because of this Demon Spirit Art?
Of course not.
Ling Yi's Demon Spirit Art is a skill, and as a systematic skill, it naturally has the imprint of the system.
The Demon Spirit Art learned by the Demon Spirit Academy are truly just Demonic Yuan spells based on demonic energy.
Therefore, betrayal is impossible.
Ling Yi checked his data interface; his Energy Points had now accumulated to 13 million.
Ling Yi decided to go all in on all his Energy Points and upgrade the system again.
[Ding! 80,000 Energy Points consumed. Congratulations, host! The Infinite Passive Charging System has been upgraded to version 5.0!]
[Ding, remote charging mode activated.]
[Ding! Lottery Function for specific categories has been added. The Energy Points consumption for Lottery in specific categories will increase tenfold.]
The new features are not displayed on the data panel.
But Ling Yi's mind was filled with instructions about remote charging and specific categories of Lottery draws.
Remote charging: All the creatures under Ling Yi's control can consume their own energy to remotely charge Ling Yi.
This feature caught Ling Yi's eye.
In that case, Ling Yi wouldn't need the Demon Spirit to run back and forth every night.
Charging efficiency will be greatly improved.
The idea of categorizing Lottery is easy to understand. For example, a regular Lottery requires 100 Energy Points, but if you specify Lottery type, such as weapons and equipment, in the regular Lottery mode, it would require 1000 Energy Points.
The same principle applies to Lottery, Lottery, and premium Lottery.
"Continue upgrading!"
[Ding! 160,000 Energy Points consumed. Congratulations, host! The Infinite Passive Charging System has been upgraded to version 6.0!]
Hmm, that's it?
No new features to add? Then let's continue!
Since we're going all in on all Energy Points to upgrade the system, we can't stop now.
[Ding! 320,000 Energy Points consumed. Congratulations, host! The Infinite Passive Charging System has been upgraded to version 7.0!]
[Ding! 2.56 million Energy Points consumed. Congratulations, host! The Infinite Passive Charging System has been upgraded to version 10.0!]
[Ding! New feature added: Clan Collar!]
[Ding! 5.12 million Energy Points consumed. Congratulations, host! The Infinite Passive Charging System has been upgraded to version 11.0!]
With the final "ding," the system was upgraded to version 11.0.
However, only version 10.0 added a Clan Collar feature.
This feature still hasn't appeared on the data panel.
However, this does not diminish the power of this feature.
Clan Collar, available for purchase with Energy Points.
Once a group of beings is given Clan Collar, any other member of the same group that has come into contact with that being will be controlled by the Clan Collar.
This is an incredibly powerful, yet equally evil, feature.
For example, if Ling Yi puts Clan Collar on a certain Demon Person, then any other Demon Person who has come into contact with that Demon Person will be controlled by the Clan Collar.
It's important to note here that she was controlled by Demon Person wearing Clan Collar, not directly by Ling Yi.
Ling Yi can only control the Demon Person wearing the Clan Collar, and then that Demon Person can control the other Demon Person.
The final results may seem similar, but there are actually quite a few differences.
Because Ling Yi cannot directly give orders to other Demon Person, all orders must be relayed by Human Reincarnation wearing collars.
Another point is that once the Demon Person wearing the Clan Collar is killed, the Clan Collar will disappear, and the other Demon Person will naturally lose control again.
Even with its flaws, the Clan Collar are powerful enough.
With its powerful functions, it naturally consumes a significant amount of Energy Points.
The more powerful a creature is, the more Energy Points its Clan Collar consumes.
The exact consumption will only be known after testing.
I checked my Energy Points; I still have over seven million.
Ling Yi's Ying Yi and appeared in an alley behind the Ruyi Residential Complex.
There was a minivan in the alley, and there were three people inside.
To be precise, they were three powerful Magic Cultivation.
They were all at the Demonic Yuan Realm.
The van looked ordinary, but it was filled with all sorts of high-tech listening equipment.
The surveillance footage showed the front door and windows of my second uncle's house in Ruyi Residential Complex.
There was no footage of the room itself; perhaps these people were worried that Ling Yi would discover the surveillance equipment, so they didn't dare install it inside the room!
As for the origins of these people, Ling Yi was too lazy to ask, nor did he care to know.
Ling Yi hovered on the roof of the van and began communicating with the system to purchase the Clan Collar.
[Ding, consume 10 billion Energy Points to use the Clan Collar on the "human" creature?]
Ling Yi frowned. Did putting Clan Collar on a human really require so many Energy Points?
But thinking about it, it's not surprising. After all, humans are highly Wisdom beings with unlimited potential, and 10 billion units of energy is indeed very expensive.
However, if just one Clan Collar could potentially control the entire human race, then the price is acceptable.
I can accept it, but I can't afford it.
Afterwards, Ling Yi went to a laboratory at the Dafeng City Bureau 503 Security Bureau.
This place holds many Demon Person who have been captured and used for experiments.
The Demon Person Clan Collar costs 1 billion, which is ten times cheaper than the human Clan Collar, but Ling Yi still can't afford it.
After thinking for a moment, Ling Yi left Dafeng City and went straight to Red Maple Mountain.
Red Maple Mountain is still shrouded in extremely dense Demonic Qi, but there are no longer Demon Person inside.
The Demon Person will either be captured by Bureau 503 for experiments, or he will be killed!
Nowadays, finding a Demon Person in the wild within the Ancient Country has become quite difficult.
Of course, Ling Yi didn't come to Red Maple Mountain to find the Demon Person, but rather to find the Beast within Red Maple Mountain.
Ling Yi used his Divine Sense to quickly locate several wild boars.
[Ding, consume 1 million Energy Points to apply the Clan Collar to the "Half-Demonized Wild Boar" creature?]
Ling Yi directly chose "no".
Red Maple Mountain isn't very big, and there aren't many Beast. Finding even a few wild boars is already quite a feat.
Even if we did use the Clan Collar on them, they would most likely be wasted.
After all, the most effective use of Clan Collar Clan Collar for a wild boar wearing one to come into contact with its own kind.
But these wild boars will most likely be unable to leave Red Maple Mountain.
Even if it becomes demonic in the future, it will be quickly killed by Bureau 503.
"Has he become half-demon?" Ling Yi murmured.
It probably won't be long before these wild boars are completely transformed into Magical Beast, right?
Ling Yi then tested the other creatures on Red Maple Mountain.
Half-demonized rats require 3 million Energy Points for their Clan Collar; half-demonized Rabbit require 1.5 million; half-demonized snakes require 2 million; and half-demonized sparrows require 1 million.
Ling Yi roughly understood that the amount of energy consumed by the Clan Collar was determined by the race's potential.
Take, for example, the half-demonized rat.
Mice may seem small and weak, but they have the advantage of numbers and a high rate of reproduction.
If a rat is corrupted by demonic energy, it will directly transform into a demonic Magical Beast at the Demonic Core Realm.
Imagine the devastation caused by millions upon millions of the Demonic Core Realm rats in the Lin Zhong – what a terrifying amount of destruction that would ensue!
Therefore, after finding the semi-demonized rat, Ling Yi directly selected the largest adult rat, consumed 3 million Energy Points, and used the Clan Collar.
Then, Ling Yi gave the rat an order: once it had completed its demonic transformation, it should lead its clan to wipe out all Magical Beast it encountered, but it was forbidden to harm humans.
Perhaps, this mouse will bring Ling Yi a pleasant surprise.
"What if all Beast and creatures were corrupted by demons..."
Even Ling Yi felt a chill run down his spine at the thought of the overwhelming number of Magical Beast.
Especially those creatures known for their sheer numbers.
For example, cockroaches, mosquitoes, flies, locusts, etc.
Ling Yi couldn't help but think of the Lin Clan again, his killing intent boiling. Humanity is now surrounded by dangers, yet these trash are still only thinking about internal strife.
The Lin Clan is doomed to be destroyed by Ling Yi!
"System, grant a special Lottery of a specified category!"
[Ding! Please specify the Lottery category!]
"Message transmission tools, cultivation techniques, or magical artifacts are all acceptable!"
[Ding! Do you wish to spend 1 million Energy Points for a special Lottery for a "communication-type cultivation technique or magic item"?]
"Consumable!"
[Ding! Congratulations, host, you have obtained 100 Message Transmission Jade Plaque!]
The Message Transmission Jade Plaque tablet can be activated by consuming energy such as Demonic Yuan or True Yuan to send messages.
Each Message Transmission Jade Plaque has a unique identifier, somewhat similar to a mobile phone number. Once the identifiers are entered, messages can be exchanged between the pendants.
There are no restrictions on the scope of the communication.
As long as there is enough energy, communication can be transmitted even at the ends of the universe.
The Message Transmission Jade Plaque tablet was powerful, but it wasn't what Ling Yi wanted.
"One more time, this time specify a cultivation technique!"
[Ding! Consume 1 million Energy Points for a special Lottery for a "communication-type skill"?]
"Yes!"
[Ding! Congratulations, host, you have obtained the cultivation technique: Sound Transmission Technique!]
Ling Yi's mind immediately filled with techniques for using Sound Transmission Technique.
This thing is quite complicated; it doesn't seem easy to learn.
The Sound Transmission Technique sounds simple, but in reality, it is a very advanced technique.
Moreover, this Sound Transmission Technique has different levels. The beginner level can only Voice Transmission for ten miles, the intermediate level for a hundred miles, the advanced level for a thousand miles, and the Perfection Voice Transmission for ten thousand miles.
Of course, Ling Yi doesn't have these troubles.
The Sound Transmission Technique has been directly listed as a skill in the data panel.
As long as Energy Points are consumed, you can Voice Transmission to a designated target.
The distance and quantity of Voice Transmission determine the amount of energy consumed.
Ling Yi immediately conducted a test, sending a telepathic Voice Transmission to Demon Spirit No. 72, instructing it to bring the demonized Houzi from Kunshan to Dafeng City.
The No. 72 Demon Spirit is located on the border, more than 10,000 kilometers away from Dafeng City.
Voice Transmission over 10,000 kilometers consumes 1,000 energy points, equivalent to winning a mid-level Lottery.
However, Ling Yi doesn't lack that little bit of energy right now.
With a thought, Ling Yi used the remote charging function.
[Ding! Energy Points +25 million!]
