Elemental Dissonance.

Reading the whole letter, he was thoroughly convinced he hadn't gone mad after the truck crash and all this was happening in real life and wasn't a hallucination. He then closed the 'For survivors' letter and opened up the 'System Tutorial' letter using the same trick in a backward fashion. 

Although he wanted to check out all the tabs by himself, he refrained himself doing that because 'Haste makes waste'. And the huge amount of emphasis the previous letter had shown clearly this thing is important, so he just opened the tab and then a similar screen opened up before him. 

[Welcome survivors, this would be the very first message you would most likely read, but believe us it won't be the last. You arrived in this inbox section either by the guidance of System or by yourself if you're a fan of Cybernetic implantations or Scientific novels. 

No matter how you arrived, this tutorial is the same for everyone just like the System is, this message is meant for the Survivors to be masterful and be smart with the System. 

First and foremost thing is properly communicating with the System. The system is a self-developing AI and it has a name 'System', please refrain from calling it Tool, voice, Demon, Demonic Tool voice, etc. 

As for how to reach it, just think about what you want it to do System can read thoughts and memories of its Host, so don't start murmuring in public as not many people in this world currently have a System and would mistake you for a psycho.

Yes, you read correctly although the System's claim of everyone having system is wrong, it isn't false either our original goal was to propagate the System to everyone but due to some unfortunate event we couldn't do that and ended up with only 5 million users. And the probability of you spotting another system user is less than 1%.

Now let's move on to some main functions, as you have probably encountered this message before (Research /Records /Modules /Mission /Shop /Status /Network tabs added.)] 

Although confused he still got what they wanted to say and so he read further. 

[What does it really mean? Most of the system functions are meant to be based on this R2M2S2N model as we like to call it. These are the Main tabs which you can use in Tabs mode, the default mode you're using currently is Survival log mode which records, analyse and present data to you in layman terms, you just have to think of changing the modes.

Research= It is the section which mainly deals with analysis, calculations, design making and 3D simulation it runs by a  powerful Virtual Reality engine and is very efficient in making 3D models. 

Records= It is the section where Survivors can record useful information and can share to another survivor, purchasing and selling of information is also done here, it acts as a forum for Survivors. 

Modules= It is the section where Survivors can see their own modules, as for what modules are? Modules means your lifetime skills rated by our module department, there are 4 levels of each modules Beginner, Intermediate, Advanced and Expert. 

Mission= It is the section where System administrators directly handout special tasks and by completing those you'll get a currency called Mission stars which in turn would be used in the purchase of Modules and useful information. 

Shop= It is the section from where Survivors can buy and sell various modules, and yes you can share and purchase the experience of a particular skill with the help of the System. It is further divided into two sections they are System shop and Global shop, System shop is where the survivor can buy Modules directly from the System and Global shop is where the survivor can buy Modules from other survivors. 

Status= It is the section where Survivors can view their health and fitness conditions with the help of a simple system body scan. 

Network= This is the section where you're currently reading this letter, this section is divided into 3 minor sections they are Inbox, Outbox and Updates we are assuming everyone would know their purpose so let's skip it. 

The last section of this System Tutorial is the Special provisions mode, it is the Third system mode alongside the System log mode and Main tabs mode. The special provisions mode is the mode which would activate automatically when the Survivor is stuck in a life-threatening situation and there's no other way. It would activate and search the module database for Modules useful in that particular situation, you can also activate it manually but beware you only have 3 chances for it. The modules unlocked during the special provisions would be retained. 

Don't put all the hopes on System as it is made by Humans, not by Deities. After reading this, read 'For survivors' letter and get ready for preparation.] 

Reading this whole article he truly came to know how much preparation these people had done in creating the system and how much capabilities this thing have. 

'System close the network tab and enter Missions tab' 

He tried commanding the System with the method described in the tutorial. Not much to his surprise it worked, the Network tab closed and a new tab opened. 

[Network available, downloading details 1%...20%...Complete.] 

[Missions available: 1]

[Preparation for survival: For survival, you need proper preparation, you have been given the chance, don't waste time.]

[Time limit: 4 hours 38 minutes/ 2 days.]

[Remark: You're late for preparation, but not for survival. Fool, Steal, Rob or even kill, do anything to get the preparatory materials and survive.]
