Dan can't keep calm anymore due to new world experience and also for upcoming talent appraisal examination. He searched his house for books but found a single book which was kept inside a locker very carefully ... Dan asked his mom's permission to lend the book but Lana hesitated for a moment because books are very expensive in this world ... If you are not a noble, you can't keep a book in your possession . There is no chance for peasants to buy books . To buy a book in this world a noble need to use family emblem at town council store and pay a lot gold ... Dan told his mom that he needs that for his upcoming examination. His mom agreed to lend the precious book with golden cover ' book of basic knowledge ' with a simple condition ... Dan already learnt alphabets and basic words from his dad , so it wasn't a big problem to read the book . Dan shut the door and opened the golden coverd book .. A lite lamb skeen smell lingered in air and those black letters surfaced on the page automatically. Dan decided to read it with exceptional care and store all data in his memory chip . This book contains basic geography of this planet , basic history , basic science , basic knowledge of courtesy etc ..
