.Hack Infection Money Making

An easy way to do it is to buy Amatuer Blades at the Delta server weapons shop and find Springs of Mist and change it into something better.Not only does this make you some money but it also gets you farther in your Books of Ryu.The easiest way to find them is to add anything for the fisrt two keywords and for the last one...You add Sea of Sand or Aqua Field.And also take into consideration if it's about level 15 or lower it will most likely be Monsieur.If its 20+ it's most likely a Grandpa.And Grandpa is better then Monsieur.Unless you're just beginning the game I'd reccomend using Monsieur. You use A Fairie's Orb to make sure you don't run into a Magic Portal.Use a speed Charm if you have one. Make your way to the Spring throw in the Blades and choose Neither.Almost everytime you'll get a better weapon.Rinse and repeat.

This isn't excatly the "advanced" way to get money but it takes more time but with greater reward.
The best way is to just dungeon rush.
Dungeon rushing is where you go straight to the dungeon kill all the monster and loot all the treasure chests.
You could also Data Drain monsters but it takes longer but also, better reward.
If you don't want to level up go to a place under or 10 levels lower.
The best place to go is end/post game.
Anywhere where there are Mu Guardians.
Their Data Drain item is Bom-Ba-ye.
These are the, if not closest to best Twin Blade weapon in the game.
You could also Data Drain any monster level 20+ and get decent to excellent weapons and armor to sell.

This was my guide for .Hack Infection Money Making.
Maybe wasn't the best but I did this and it got me through the game with ease.
Thanks for reading!
