"So how do I use the Secret Stone of Time for time travelling?" Shaun couldn't take his eyes off the secret stone hovering above his palm.
"It begins and ends in the Spirit Realm. You have to first open a portal into the Spirit Realm, after closing the portal then open the secret stone of time with your spiritual power, you will enter a cylinder time tunnel, which is a concrete representation of time as a new dimension that you can reach. I believe you have already experienced that tunnel before you woke up and the main timeline of this civilisation is imprinted in your consciousness. That is the effect of being correlated by the Secret Stone of Time." The Spirit Realm Guardian replied to Shaun.
"You can choose to slow down the passage of time after you enter the time tunnel to help you enter the point in time you want to enter. After entering you are still in the Spirit Realm space at that point in time and need to open a portal into the real world."
"Using the Secret Stone of Time to open a time tunnel in the real world is prone to causing overlap between different time zones, causing the tunnel to collapse triggering a temporal collapse."
Saying this the Spirit Realm Guardian looked at Shaun and said stiffly: "In short don't use the Secret Stone of Time in the real world."
Shaun activated his spiritual power to put away the Secret Stone of Time and then asked, "What if I die in that time and space?"
The Spirit Realm Guardian and the Demon King looked at each other and this time it was the Demon King who spoke up and replied, "Don't die. Otherwise you can only wait until the next agent who finds the Secret Stone of Time returns to the past to change history to save you."
Shaun couldn't help but cover his face with his hands. "Then I'll call my parents okay, maybe I'll never see them again." Shaun wanted to cry a little.
"As long as you don't die, no matter how long you stay in that time and space, we're only here for a minute. So either you can't come back or you'll be back in a minute. When you come back I'll help you get your body back if you've aged from living over there too long. There's nothing you can do if you die over there." The Spirit Realm Guardian said coldly.
"I'd better go and come back quickly." Shaun muttered inwardly.
"Given that you have descended into the world as the son of a demon, you will be well protected by the servants and have a lot of resources at your disposal. That organisation has just been set up, and you can even join them as a high-ranking member. So when you get there, your real enemy is not that organisation, but the church and some folk demon hunters with supernatural abilities." The Demon King said.
"You passed through the time tunnel before you woke up, the important timeline is already imprinted in your mind, it's up to you how to make use of those important historical events. We'll alter your appearance a bit, it's not common to see Cologne Asians in those times, it won't help you act." By the time the Spirit Guardian had finished speaking, Shaun had felt something change in his face.
Shaun hurriedly took out his mobile phone and set the camera to a selfie angle to look at himself, only to see that he had completely changed into a blonde white man in the camera.
"That's too much of an alteration!" Shaun exclaimed miserably.
"If you know anything about that time period, you should know that having a purebred Germanic appearance will facilitate your actions." The Spirit Realm Guardian said.
Shaun knew in his heart that the Spirit Realm Guardian was right and could only accept the face.
"In Cologne in 1900, I remember a group of servants who had secretly performed a rather large summoning in April, when I responded to them. A few of that group of servants were quite powerful nobles, so you descended during that ceremony and asked them to assign you an identity." When the Demon King finished, he saw Shaun's puzzled look and smiled a little before adding, "Don't be puzzled, in that watershed era, the number of people who believed in demons wasn't too small, at least not less than those who believed in the Scientologists."
"Remember who you are, to those servants you are a god, maintain that persona, show power when appropriate, but not too much."
"... How far does one go to complete the task?" Shaun asked.
"Pull some of them together, crush some of them, as long as you don't let them form an alliance, one or two clans alone can't do something like create Chaos." The Demon King's smile brought out another wry note, "The easiest thing is that you can get some of them to be intimidated by you and to ascribe their faith to you. Those that don't listen will be uprooted."
"Act fast, the world is waiting for you to save it. Chaos has used the Mob Alliance's arms dealing network to place over five antimatter bombs around the world, and it is the nine families that have the ability to access antimatter in the particle collision labs that have been secretly set up by those nine families. And The One, the monster that set off the antimatter, and there's no telling how many genetically modified monsters like that they've created."
Shaun exhaled and said, "This time and space minute, it's possible I'm over there for life right? Can you make a phone call?"
The Spirit Realm Guardian threw him an orb with energy fluctuations, "Use this to make a call."
The orb changed into the shape of a phone and Shaun dialled his home number, the call came through and it was Shaun's mum: "Hello?"
"Mum, it's me, what are you doing?"
"Shaun, why are you calling at this hour, thanks to your dad and I sleeping late today watching TV shows, or else you would have woken me up just as I fell asleep. Are you okay?"
"I'm fine, Mum, I just missed you guys and forgot about the time difference."
"Have you finished your tour? How many days until you're back?"
"I'm almost done, I'll be back in a week. Mum, you and my dad ..."
"What's wrong, son?"
"Nothing, don't go out much these days, it's not safe out there."
"Okay, we will take care of ourselves, you pay attention to your own safety outside. Take the initiative when you meet a girl you like ..."
Shaun listened to his mum's nagging on the phone and smiled, but the tears couldn't help but flow down ...
Back in time, after Shaun was transported to the Spirit Realm by the "Coffin of Stasis",Chaos on the spire of the cathedral sat cross-legged on the spire, his chin propped up in his lap with one hand, looking into the distance.
"Back in the Spirit Realm? There are some very interesting things in the Spirit Realm! Ahhhhh! Find a way to check it out la la la! La-la-la-la!"
