The accumulation at the first level partially determines the accumulation at subsequent levels.
Originally, in order to continue improving the Spiral Tower after it has been completed, a great cost and countless effort had to be made.
But now Ivita's Spiral Tower changes automatically, with iron chains appearing one after another. These chains stretched swiftly, producing violent noises similar to moving iron locks.
These chains are Ivita's previous accumulation, parts hidden within the Spiral Tower that hadn't been developed, but now under 'Ivita's' guidance, they had been fully brought into play.
These chains are scattered all over the maze. Some chains are covered with rust, looking like ancient artifacts; some chains are flawless, as if they were just forge-made.
After the placement of these massive chains throughout the maze, the dungeon seemed even more intimidating.
