The room was luxury it has a touch of gold which was sparkling and it hurts my eyes like 'hell'. In the Hell it was always night and dark,it has a lot of gems which are prettier but have not seen any gold. On they other hand heaven has a lot of gold like really lot all the palace of God's are made of gold even the angels had their armor as gold it's hurt my eyes so much. The Sun God is a walking gold, his hair is gold even his blood is also gold.
Our protagonist went to sleep or forced himself to sleep in an unfamiliar surroundings but a knock woke him up from is sleep.
"Pardon me, Lord Marshall his grace have left a letter for you."
Our protagonist was thinking whether to kill this human called butler for waking
him up from his so called sleep but decided to control himself. Our protagonist open the door and got the letter and closed it tight. He opened the letter the first sentence said 'Dear Lucas' the second sentence read as 'Common sense for a Demon Lord who is visiting the human realm' the urge to kill the butler which he suppressed was now directed to his friend. Lucas throws the letter on his bed and was ready to open a portal and kill his friend but our protagonist unlike other demon lord's he doesn't have anger issues and kills someone on the spot without using his mind. He calms his mind and picked up the letter there must be a reason why his friend sent this letter, the last time he visited human realm was to clean up some 'flies' and it was about 1200 years ago... maybe he need to read the letter. Lucas finished reading the letter and he noticed there is a lot of changes in human realm since his last visit.
Like the fact the there are 4 forbidden areas namely: Nameless Castle, Ash Forest, Crow's Den and Gate to Afterlife. Lucas didn't know what these forbidden areas are in his last visit to human realm there where not present.
His friend is in position of Marques in the Empire of Cenia. There are four important landmark like: Magic Tower, Ruby Tower, Alchemy Tower and Magic Academy. The four landmark was present in his last visit so he knows them.
The currency the use are Copper Coins, Silver Coins, Gold coins and Crystal Coins. (1000 Copper coins=1 Silver coins, 1000 Silver coins = 1 Gold coins and 1000 Gold coins = 1 Crystall coins.) Having Crystal coins means you are so rich and only or mostly the royal family is in possession of it. The second paragraph of the letter spoke of the magic academy and how a teacher should behave and how a teacher should teach whatnot but the most catchy my the paragraph is this line 'The students... some are dangerous, 3 students have divine powers and I don't know which God blessed them.' For a Demon Lord divine power is their weakness our protagonist friend didn't mention the students name so Lucas is the one who need to find them. Which is annoying for him.
Though the divine powers might not work at him at all for he is friendly with few gods. Since heaven and hell are near to each other you get to talk to them about gossip or business with the gods or angles. Well Lucas will figure it out in future.
