Chapter 7: Exorcism by Science and Technology

"Arrogant mortal!"

The blue data stream in front of him was angry, its code was jumping, and then it turned into the image of a traditional Tzeentch demon composed of binary code - a humanoid monster with a lizard head and bird wings.

He flapped his wings and circled in front of Leon. "Even that techmarine didn't dare to communicate with me like this. How dare you, a mere mortal, be so presumptuous?"

"He's so polite to you because he doesn't know who you are."

Leon pointed out the blunt truth: "Why, you are trapped here and don't want to go out, pretending to be a machine spirit and playing with the technmarine who doesn't know demons, can this level of conspiracy satisfy your evil taste? That's too much of a shame for the bird-headed man above you, isn't it?"

Unlike the Indomitus era when demons were rampant, in the period of the Great Crusade before the heresy, not to mention the Space Marines, even the Primarchs had little specific knowledge of the Warp and demons, and the Empire, which was still promoting the Imperial Truth, did not recognize the existence of demons. 

Although demons occasionally invade the real universe, they are just classified as xenos

Leon was not surprised that Sergeant Hank would regard this demon as a machine soul, but he was very interested in why this demon was here.

Leon's words angered the demon. He flapped his wings and shouted at Leon angrily: "Mortal! What do you know about my Lord? My Lord's plan is linked together and seamless. I am also a part of my Lord's plan here! How dare you, a mortal, speculate on the deep meaning of it?" 

He surrounded Leon, his eyes revealing undisguised greed: "It just so happens that I have been here for a thousand years. During these thousand years, I can only survive on the cold energy input from the outside world, which can't satisfy me at all! Today I will use you as a diversion, let me devour the soul of a daring mortal like you!"

As he spoke, the Tzeentch Demon could not wait to manipulate his data stream and wrap around Leon. He intended to follow Leon's code and try to enter Leon's body along the data line in the opposite direction. Leon was too lazy to resist at all. He let the Tzeentch Demon perform and even took the initiative to open it. 

The Tzeentch couldn't wait to get in, but he got in fast and came out even faster. In just the next second, he ran out of Leon's body screaming.

The Tzeentch demon was smoking all over, and his eyes were full of anger and fear when he looked at Leon.

"You are a blank?!" Tzeentch shouted angrily, "Why didn't you say so earlier?!"

"I thought you were asking?"

This time, it was Leon who pressed forward step by step. The Great Demon Tzeentch withdrew nervously: "Why, where is your arrogance now? Aren't you the Great Demon Tzeentch who knows fate? Don't you still have no idea about your future fate?"

The great demon Tzeentch made up his mind, closed his eyes, stretched out his neck, and posed a posture of waiting for his death: "Kill me, we demons are immortal! Remember me, mortals, I will come back to find you one day!

Leon raised his eyebrows in surprise. He didn't expect that a Tzeentch demon could have such integrity.

However, considering that this Tzeentch demon was probably killed by the veteran and forced to play the role of an electronic demon in the real world, this dreadnought is more like a cage for him.

If the demon couldn't possess another body, then Leon, as a blank, sure can't. Leon thinks he probably wanted to go back to the warp to be resurrected a long time ago. 

If it were any other situation, Leon would not let the demon go so easily.

Unfortunately, Leon had neither the Mechanicus's exorcist incense nor a special robot servant that played the Omnissiah prayer repeatedly with a loudspeaker.

Since he couldn't use the ritual of technological exorcism to torture this demon, Leon simply wrote an antivirus program and planned to hurry up and send this demon to its death.

But the moment the antivirus program written by Leon encountered the Great Demon of Tzeentch, it jumped up like a frightened cat.

"No, no!" He screamed and moved away from Leon. He looked at him strangely, not understanding what he was doing.

"Didn't you ask for death? Why are you running away?" Leon asked.

"Yes, right?" The Great Demon Tzeentch was still a little hesitant. He carefully approached and touched the antivirus program, then screamed and ran away: "No, no!

Leon looked at the strange behavior of the Great Demon Tzeentch, and after thinking for a while, he replaced the antivirus program he had with the universal version widely circulated in the forge world.

The Tzeentch demon suddenly became excited again: "Right, right!" The excited demon rushed towards the universal version of the antivirus program with the momentum of a rainbow piercing the sun, as if he wanted to ram himself into it and die.

Seeing him like this, Leon, who had a rough idea in his mind, immediately replaced the general version with the program he wrote.

Such a sudden change made Tzeentch scream. He struggled desperately, trying his best to stop his previous momentum of crashing into the antivirus program and stop suddenly in front of the modified antivirus program.

He looked at Leon in doubt and wonder: "Are you a believer of the corpse emperor or a lackey of the C'tan? What sin have I committed to run into someone like you!"

Leon keenly grasped the key words and looked at the great demon with interest: "Why? The cost of returning to the warp is too much for you to bear?"

"It's worse than that!" The Great Demon Tzeentch screamed, but he immediately lowered his voice and put on a negotiating attitude: "How about this, you let me go, before I leave, I can answer nine questions for you, as long as I know, I will tell you everything!"

"Why Nine questions?"

"This is the rule of the Lord of Change." The Great Demon Tzeentch said bitterly, "If I violate this rule, unless the Lord of Change himself shows extra mercy, even if I return to the warp, I will not be resurrected by the Lord of Change."

"Okay, then tell me why you don't want to be killed by me."

"This is the only thing that won't work!" The Tzeentchian Daemon screamed again.

"Then tell me the real name of the Lord of Change?"

"You..." The demon began to get angry and said, "You don't even think about letting me go!"

"Didn't I raise a question?" Leon spread his hands: "You can't do this or that, which makes it difficult for me."

"Conspiracy! I can tell you what kind of conspiracy my superior has against their primarch! I can also tell you my real name, so that I will never betray you! Or you can make me into a weapon, and I can serve you in the weapon!"

The Tzeentch demon confessed: "As long as you let me go, I will...ah, ah - I curse you, disgusting one, I will curse you forever with my life!"

"Don't worry, it only hurts for a moment. Count the stains on the ceiling, and it will pass soon."

Leon, who had activated his antivirus program, consoled him: "Look at it in a positive light. Your death might also be part of the plan."
