This is the story of a crazy lich who possesses an internal game system and brings catastrophe to the entire world. “Let’s look at the daily quests today… it’s the damned choose one-of-two-options-type again. Destroy a town with a population of 30,000 people or above; reward: 10,000 evil points. Steal lollipops from 3 children; reward: 1 evil point. If neither of the quests is completed, then 2 points will be deducted.” “Tsk! You think I’m stupid? If I really destroyed a town, a crusade of Myth-ranked Holy Knights would definitely come hunting me down. Even if I earned the points, there wouldn’t be any life left in me to spend them. I better just go be a kindly lollipop bandit.” I’ve already had enough of being a notorious lich. Who says a lich can’t be a good person? I’m definitely going to beat this damned system and be an upright and dignified good man.
There were various types of mage towers. An example was the fortress-type, constructed especially for the battlefield. These fortress-type mage towers were rather simple in design and were typically designed to be shared by many mages. There were also research laboratory-type mage towers. These would belong to an individual mage and usually contained all of the mage's accumulated treasures. But any type of mage tower would always be a super dangerous area.
Having a personal mage tower meant having one's own world. Not only would the mage tower massively increase the mage's combat power, all sorts of esoteric and high-level magic spells would become much easier to cast due to the support of all the expensive magical ingredients, dimensional portals, batteries, and so on that a mage stored in their mage tower.
