I really don't get why he's not sharing the irregular spawn condition info with the general public. If people knew what caused the spawns, then there would be far fewer deaths and the prices of the ores and low level equipment would drop. Which would make it much cheaper for him to make higher tier equipment, which would make it easier for him to get rich faster. I also don't understand why he's not sharing any info about the item book with his party. Does he just not trust them to keep it a secret? If he does trust them, then knowing about it will improve team motivation and make it easier to horde ores and items rather than selling them to the government. He should also consider teaming up with that merc group to make and sell items. If he did, he could make a vast fortune far more quickly and cheaply. Assuming that he could trust them of course, but that's what contracts are for and allying with them would give him quick access to gear of all levels. Heck, even if he doesn't trust them enough to ally with them, he could still probably rent equipment with them based on their current relationship (if he hadn't just cut ties with them). Alternatively, he could just work up a bit of money and start buying cheap weapons and ores. None of the things he actually knows how to make reliably sell at a loss, so he should be able to snowball it quite easily and quickly increase the number of extremely expensive items that he knows how to make. He could even create exclusivity deals with hunter parties to get them to sell their drops to him instead of auctioning them off or selling them to the government. It would be cheaper for him and more rewarding/stable for them. I'm sure people would catch on eventually, but by then he should be one of the richest people in Korea. So even if the government forced him to turn over the recipes, he should still be in a very good position to continue making money in some other way.
