Exorcist's Self-Cultivation

[Master, please don't do this...] [You want to know about the past, and there's no issue with lifting the Envelope's restriction, but even then, the Envelope couldn't possibly know what all has happened in the past...] [The Envelope once wandered, having lost its purpose of existence, but ever since meeting you, the Envelope has discovered that you are its guiding light, your every word sets the Envelope's blood ablaze.] [The Envelope is willing to die for you, but as for your girlfriend's matter, the Envelope really doesn't know, and can't do anything about it...] At this moment, the Envelope trembled violently, almost on the verge of collapsing. Yet Du Wei remained indifferent, still looking coldly at it. The temperature around them was plummeting wildly. Waves of cold seemed as if they could freeze everything. What kind of person was Du Wei? This, the shadow should understand very well, having followed Du Wei for the longest time, with the cleanest slate, and also being the most "loyal and devoted." If it could speak, and its relationship with the Envelope was not bad, it should have reminded the Envelope. Even if it was impossible, it must be done. Otherwise, refer to those special objects used up by Du Wei and some evil spirits. Their endings were all witnessed by the shadow. Du Wei looked at the Envelope and said in an icy tone, "An Evil Spirit Envelope actually possesses independent will, and has demonstrated intelligence, knowing to hide its own secrets." "And it's even willing to acknowledge me as its master, playing the part of a lapdog, do you think I'm easily fooled?" [The Envelope doesn't understand what you mean...] [The Envelope's loyalty to you can be attested by heaven and earth...] Du Wei coldly said, "Since you put it that way, then I will take everything you've said as truth." "But if you are indeed loyal to me, then you must firmly carry out my orders, meet my demands." "And you're now telling me it's impossible?" [But... but the Envelope really can't do it, because that time was simply too long ago, the Envelope can only materialize events that happened in the past, and there are even many things the Envelope can't find out about] Du Wei took a deep breath and snapped his fingers. The lighters surrounding the Envelope burst into a raging inferno. With a bang. The entire Envelope was reduced to ashes. Then, the Envelope that had been burned to ash was resurrected once again. [Master... The Envelope really can't do it...] Yet Du Wei would not pay it any more attention. The flame from the lighter burned wildly, again turning the Envelope to ash. It was quickly resurrected, only to be quickly burned again. In a cycle of repetition, after dozens of cycles, the Envelope's aura became weaker and weaker, and the time needed for resurrection grew longer and longer. At the same time, an evil aura slowly emanated from the Envelope. This was an Evil Spirit Envelope. The Envelope was its vessel, and when it could no longer maintain its facade, that was when it was at its strongest yet also at its weakest. Because it knew its great "master" could, like snapping the life out of a chick, pinch it to death. For the first time, the Envelope felt an impulse to flee from Du Wei. But it knew it couldn't escape. Not to mention the devil-like Du Wei standing nearby, even the demons beared their teeth fiercely at it. The mindless shadow, as well, had its twin blades locked onto it. Already aboard a thief's ship, escape was not so easy. Indeed... The Envelope had its own will, all of its previous justifications to Du Wei were deceitful. And its creator wasn't the Dusk Bell Church. It was just because the Dusk Bell Church had discovered it. Of course, the Envelope indeed couldn't manifest events from dozens of years past. That had surpassed its capabilities. In the end... When the Envelope was almost unable to hold on any longer, it finally compromised. "Master, the Envelope has found a way, the Envelope has found a way!" A burnt piece of paper desperately flew out from the flames; just as it was about to be consumed entirely, it finally presented these words before Du Wei. Only then did Du Wei snap his fingers, causing the lighter's wind guard to automatically close. All of the flames disappeared without a trace. Then, he looked down at the Envelope that was slowly resurrecting from the ashes, all the Evil Spirits behind him mimicking his actions. "Ten minutes ago, Master, there were signs of emotional overdrive because you discovered that something was wrong with your girlfriend; you suspected she wasn't human. But you know, the woman you first encountered was this Alex who has been by your side day and night." "Now you've calmed down, and you want to know what really happened in the past, to solve this issue," "This may relate to the man who made the prophecy, or maybe it has something to do with a demon curse." "The Envelope cannot tell you everything that happened in the past, but if you lift the restrictions, the Envelope can find the being that can fulfill your purpose." Looking at the words on the Envelope, Du Wei's dark eyes were filled with an ineffable indifference. He just wanted to know why his girlfriend could be Marked by him, whether something bizarre might happen, and if it was possible to nip the problem in the bud. Put simply, Du Wei didn't trust this Evil Spirit Envelope. Because he never forgot, this thing had its own agenda. The last thing to give him such a strong sense was the Antique Clock. All of it—the curse, the visions of death—started with it. Deep in thought, Du Wei mused, "Power can corrupt, it can immerse people so deeply that they overlook the details." "When I entered this world and personally witnessed those bizarre entities, I became unable to extricate myself." "That's why I despise this world." "One day, I'll bury them all with my own hands." Nonchalantly holding the Envelope in his hand, Du Wei crumpled it and his aura softened as all the Evil Spirits returned to their original objects. Only the shadow quietly stood behind him. Suddenly. Du Wei showed a smile to the Envelope, "You really didn't have to fear me that much, after all, you are my most loyal subordinate, how could I possibly kill you?" "The things you can't do, I won't compel you to do." The Envelope was baffled... "Master, don't you need to lift the Envelope's restrictions anymore? Don't you want to solve the issue with your girlfriend?" Du Wei said with a smile, "Of course I do, but before that, as my most loyal subordinate, I want to help you fulfill a small wish of yours." With a gesture, two Joker Cards floated before him. "Master, the Envelope is so touched, your kindness has moved the Envelope to tears, you are truly a blessing to the Envelope from heaven." Du Wei said with a smile, "It's all in my duty. Now, I say one line, and you write one line." "First, the Envelope will never be able to betray Du Wei." "Second, the Envelope will never be able to leave Du Wei." "Third, everything about the Envelope must prioritize Du Wei and harbor no malice; otherwise, it will self-destruct." "Fourth, this is an Indenture Contract, once the text on the Envelope is fully apparent, the Joker Card will fulfill the Envelope's wish, and in the case of any false text or ambiguous text, the meaning as spoken by Du Wei will prevail."
