INTO ANOTHER WORLD AS DEMON GOD

Alex-" Okay I will but you have to help me if I ever need help."

Lishia agreed and made a student-teacher contract. After signing this contract the students have to obey their teacher and follow some rules. Then Alex taught them few things and then gave each of them a skill book. They were astonished to see the two skill books because even the worst and cheapest skill books at least costs 1 gold coin. So someone giving skill books worth 2 gold coin for free is not someone can easily can do and the skill book Alex gave was a rare skill book costing 4 to 5 gold coin. After giving them the skill book he told them how to use it as the skill books from Alex's world were learned differently which was very easy. The user have to chant a line and the skill book will vanish and become a light and enter the body and information about the skill gets into the user. By using the skills more one can increase its strength. The skill books he gave were-"Wind Slash" and "Poison bind". The skill books in this world had to be learned by practicing. Then he returned to his room and then contacted Rylis through mind communication and asked him if there was any problem and then called Serena and talked with her for a long time. Serena was managing both the guild and his world. Then after talking with her, he practiced his skills little bit and slept. Next day he took the class as usual and went to the library to read more books. While reading he heard students and even the teachers talking about his guild BLACK DRAGON. His guild became the strongest guild in the world with most A-ranked and B-ranked adventurers.
