Returning to the Mysterious Era-Chapter 331 - Double Agent Demon!

After some deliberation, Cassius's thoughts gradually became clear. Perhaps, that possibility existed. Dark creatures such as the Shadow Demon and Dead Blood had various methods to parasitize humans. During his time-travel, Cassius had slaughtered and absorbed a large number of Dead Blood and gained a deep understanding of its unique life characteristics.

Lower-level members of the Blood Spirit Society generally existed as a symbiotic relationship between humans and Dead Blood. By the middle level, Dead Blood had completely taken over the body's control. At higher levels, the original human would simply be a vessel.

When Cassius absorbed life vibration energy, he discovered a common phenomenon among them. He could assimilate life magnetic fields!

The life magnetic field in the human body would gradually be influenced by the life magnetic field of Dead Blood until their frequencies aligned. The higher the level of the Blood Spirit Society members, the more obvious the phenomenon became.

Cassius speculated that the control and assimilation of the Dead Blood's life magnetic field was closely related to its stage of parasitism. It presented a step-by-step, hierarchical change from the one leeching to the one in control.

Then there was how the Shadow Demon replaced its host. Every so often, it replicated a body identical in power and skills to the original, and the two engaged in a fight to the death. Wouldn't this identical body's life magnetic field be the same as the host's? That was the only way the replacement could be accomplished.

Cassius felt that the likelihood of his speculation being correct was quite high. In short, the life magnetic field must be greatly related to parasitism. The act of dark creatures parasitizing human bodies was mostly a process of life magnetic field assimilation.

Cassius was familiar with life magnetic fields; one could even say he was an expert at manipulating them.

One of the most important abilities of the Golem Covert Martial Arts was to acquire life vibration energy through the Golem life magnetic field. It was known that the Golem life magnetic field was extremely advanced and inherently powerful. So far, no species had been able to resist the process of having their life vibration energy siphoned. The Book of the Devil indicated that the Golem was one of the ultimate dark creatures among the endless calamities and was ranked fifth.

Theoretically, only four other types of species could resist the Golem life magnetic field. The Shadow Demon was obviously not among them. Therefore, if Cassius used Golem Covert Martial Arts and activated the Golem life magnetic field around his body, there was a good chance that it would affect the Shadow Demon parasitizing his shadow, causing an assimilation phenomenon.

This explained why his own shadow appeared as if it wanted to escape when he was practicing and checking his Golem Qi earlier!

Cassius immediately took decisive action. He sat cross-legged, used the Golem Breathing Technique, and began cultivating Golem Covert Martial Arts.

Strands of black mist slowly started to swirl around him. They looked like winding, densely packed little snakes in the pale moonlight, exuding an eerie and sinister aura. The three core principles merged, and the life magnetic field automatically expanded across the room.

A formidable and majestic Qi instantly spread out. It was as if a predator at the top of the food chain was surveying its territory, bringing a strong sense of oppression. The air in the room seemed to have solidified.

Only a pounding heartbeat could be heard. The Qi intensified with each beat, and the air grew ever more solid. After dozens of seconds, the air was as viscous as glue and was mixed with an extremely dangerous aura. Cassius slightly lowered his head, looking at his own shadow, and the corners of his mouth slowly curled up.

The black shadow was elongated by the moonlight, and now resembled a twisted-limbed demon overlapping on the ground. Something even darker than liquid was slowly wriggling within it like it wanted to slip into the darkness on the left side of the room. It showed aversion, fear, and dread toward Cassius's Golem life magnetic field, just like last time.

"You came to me yourself. You wanted to merge with me. Now you're regretting and trying to escape?" Cassius muttered to himself like a madman. His eyes were unfocused as he gently reached out, his fingertips brushing through the air as he slowly reached for the shadow.

"How can there be such a good deal? It's because you've been subtly influencing me all along, gradually mixing my kind and lawful persona with your filthy dark creature essence... That's why my hands had to be stained with blood and others looked at me as if I'm a monster. It's all because of you! It has nothing to do with me at all..." Cassius's eyes gradually lit up, as if he had figured out something that had been bothering him.

Indeed, he had been a good kid in the world for over twenty years. He had been an innocent college student before awakening his time-travel ability. How could his personality suddenly become so violent? Wasn't it all because he was parasitized by this disgusting and filthy Shadow Demon at the same time as he awakened his time-travel ability!

Otherwise, he wouldn't have performed such bloody and violent acts in battle, like hammering someone's head into their chest, slicing a person in half with a hand blade, pulling out a person's head along with their spine, or twisting someone into a pretzel. His mood instantly brightened at the thought.

A second later, Cassius let his hand fall. He closed his eyes, sensing the Shadow Demon's life magnetic field. His vision was pitch black, and in his mind, there were only images of two magnetic fields, one large and one small. The large one was like layers and layers of black waves, surging forward, spreading in a circle throughout the entire room.

The small one was like a sandcastle built on the beach, being battered by water, with sand grains constantly falling off. It seemed to shrink into a small ball, looking inexplicably pitiful. It was as if it were the weak and innocent party.

Each time the waves crashed, water would seep into the gaps of the sandcastle, taking away some sand while leaving behind some seawater. If this continued day after day, eventually, the castle would be completely soaked by the seawater and become like Cassius.

"My guess is correct. There is indeed an assimilation..." Cassius lightly rubbed his chin, continuing to ponder.

This confirmation proved that the host could indeed influence the Shadow Demon in reverse. The next question was whether Cassius could inject his own persona and will into the body of the Shadow Demon, a dark creature, to act as a second body.

First of all, this would involve the three core principles of Golem Covert Martial Arts. After all, extracting and transferring one's persona was too abstract. It involved the spirit, which couldn't be directly manifested.

However, there was something that could represent persona and will. Qi!

Qi was the manifestation of the unity of essence, energy, and spirit when a Covert Martial Arts Practitioner reached the level of a combat artist. Qi determined the identity of a combat artist. It was an extension of the combat artist's limbs and was greatly related to the mind. For example, it was very clear that Cassius's three Personas could produce different types of Covert Martial Arts Qi!

The Main Persona produced Golem Qi from a pure training method. The Killer Persona produced Southern Dipper Red Falcon Fist Qi from a pure fist technique. Lastly, the Cold Persona produced Southern Dipper Sonic Snake Fist Qi from a pure fist technique.

Just like blood was the currency of the soul, Qi was the bargaining chip of one's persona. Could he inject his own combat artist-level Qi into the Shadow Demon's body to control its actions?

However, there was a major roadblock to deal with. The combat artist's Qi must not harm the Shadow Demon. However, Cassius had fought with Lotus, the president of the Blood Spirit Society. Qi was highly lethal to dark creatures. Although it was not quite their nemesis, the two were definitely antagonistic.

If Cassius injected his own Qi into the Shadow Demon's body, it might instantly cause it to explode and die, ruining everything. Therefore, there needed to be a kind of energy to cover and wrap the Qi, isolating it.

This energy needed to have good conductivity and be harmless even within dark creatures. Things like "essence of calamity" and "Blood of the Spirit" flashed through Cassius's mind, but he finally settled on life vibration energy.

This energy was mainly obtained from dark creatures and could be simply understood as energy converted by absorbing the life magnetic field of dark creatures. Therefore, it could certainly be re-injected into dark creatures without harm.

Since it was originally something refined at the cost of their own lives, there would naturally be no problem with returning it. Perhaps dark creatures could even absorb life vibration energy to become stronger...

Wool that came from the sheep was ultimately being used on the sheep.

Cassius's logic gradually became clearer.

To summarize, first, he had to use Golem Covert Martial Arts to gradually influence the Shadow Demon's life magnetic field through the Golem life magnetic field until it reached assimilation.

After assimilation, Cassius could then proceed with the subsequent steps without rejection or resistance, effectively refining the Shadow Demon into a factory-standardized robot. The first step was the foundation of everything; only with a solid foundation could there be a building.

Second, Cassius would inject his combat artist's Qi; using the Qi that unified essence, energy, and spirit to represent Cassius's persona and will to control the Shadow Demon's actions.

Considering the situation, the Southern Dipper Red Falcon Fist Qi represented by the Killer Persona should be the best option because the Killer Persona itself was a residual product of the dark creature. It carried the same brutal and savage characteristics as dark creatures, so it should have a higher degree of compatibility with the Shadow Demon.

Of course, it was not necessary to inject all of the Southern Dipper Red Falcon Fist Qi. Just a portion was sufficient. If Cassius's main body lost all the support of the Southern Dipper Red Falcon Fist, it might lead to an imbalance in the three core principles, causing the reappearance of recently resolved hidden threats.

That would not be worth the loss.

Third, using life vibration energy as a lubricant, Cassius would fill up the remaining space between the Southern Dipper Red Falcon Fist Qi and the Shadow Demon's physical shell.

This was both to protect and isolate the two energies, while also serving as the energy source for the Shadow Demon's actions. He couldn't have his second body learn from dark creatures to prey on humans to sustain itself, could he? That was something Cassius despised. What good was it to hunt weak humans? A real man should hunt the brutal alien species!

In conclusion, the initial idea was already feasible. Cassius just needed to completely assimilate the Shadow Demon's life magnetic field, kill some dark creatures to absorb life vibration energy, and he could start trying to control the Shadow Demon.

The reason he was so determined to do so was mainly because he wanted to extend his reach and gaze toward the dark creatures' side. Dark creatures had been hiding in the shadows of human society all along, and there were only a few channels to obtain information about them. They were a closed inner tribe that hunted humans for food. They naturally only communicated among their own kind.

It was impossible to send human spies or bribe them to obtain intelligence. They could only observe indirectly. However, dark creatures moved covertly. Some could even become invisible or intangible, parasitizing quietly, which made indirect observation extremely difficult.

Only large forces like the Black Ops Agency, supported by the federation, could obtain some useful intelligence through the accumulation of sheer manpower, resources, and time to conduct research.

Other forces, especially underground black forces like the Ace of Spades that lacked insight, even directly regarded the immortal and powerful Dead Blood behind the Duststorm organization as bio-humans. They considered them to be equivalent to the bizarre elements in the recently popular superhero comics across the federation and thought that the Duststorm organization had mastered some kind of black technology.

Cassius personally felt that he couldn't remain in a passive position. Moreover, the characteristics of Golem Covert Martial Arts made it difficult for Cassius to ignore these dark creatures hidden in human society.

Life vibration energy, whether it was used to enhance his own strength or for the expansion and establishment of his forces, was important to him. If he could truly make the Shadow Demon his second body, he could infiltrate the dark creatures' tribes as a double agent demon! It could play a great role.

He could also potentially use the Shadowless Clan. It would be best to use the Golem Seed to completely subdue them. That way, Cassius's Shadow Demon could perform some sleight-of-hand operations.

He could navigate between the Shadowless Clan that his main body was gradually supporting and strengthening, and the Shadow Demon tribe, gaining benefits from both sides and ascending step by step.

The plan was perfect. He had already scripted the scenario in his mind. All that was left was for the actors to take their places.

"It seems that as long as one is strong enough, some previously almost unsolvable deadly threats can instead become one's ally..." Cassius withdrew his palm, his face full of smiles. His gaze toward the once-despised Shadow Demon even carried a rare hint of kindness.

After that, he spent the entire night using Golem Covert Martial Arts, accelerating the assimilation of the Shadow Demon's life magnetic field by the Golem life magnetic field.

The next day, Cassius finished his cultivation at seven in the morning, quickly washed up and walked downstairs. He soon arrived at the dining area where the waiting servants immediately went to the kitchen and brought out steaming hot milk and a plate of food. The pristine white plate contained simple and delicious foods like garlic bread, Kremlin sausage, and peppered fried eggs. He sat in his seat and quietly enjoyed the meal for a while.

A middle-aged man wearing white gloves approached him. White Bird looked at Cassius with a somewhat complicated expression, almost as if he were looking at a stranger. Although Cassius had indirectly taken control of them, White Bird couldn't forget the feeling of cultivating the Golem Seed. The clear sensation of the body gradually becoming stronger bit by bit was enough to make one obsessed to the point of madness.

So at the moment, his eyes were confused, not knowing whether he had strayed onto the wrong path or had stepped onto the right one...

"White Bird, you're here? Sit down. Today's breakfast is quite good..." Cassius looked up and pointed to the plate opposite him.

White Bird nodded and quickly sat down. However, he didn't touch the knife and fork. Instead, after pondering for a moment, he said to Cassius, "We received news from headquarters this morning. A team of bio-humans from Duststorm appeared in Fengnan City and clashed with our forces. The transportation department suffered heavy losses, and many brothers died.

"It seems to be an act of revenge. Black Joker has ordered our assassination and antique departments to depart for Fengnan City today to rendezvous with experts from the other two departments. We are tasked with guarding against Duststorm's next move and launching a counterattack. Moreover, the Jack and Queen of Spades are also on their way; we might meet up in Rain Hill City and then proceed together to Fengnan City." His voice petered out.

Cassius raised an eyebrow and took a sip of hot milk. "What a coincidence. Perfect timing to do two things at once..."
