Because multiple worlds (regions) existed separately or in the status quo for a long time before they were discovered and understood by each other, they have different rules of time operation. Here, in order to make it easier for readers to master and understand the story and plot of the poem “Sea Wall”, it is specially pointed out: their differences in time.

The World, Kingdom; the Outsider, HellCity

In the twenty years after they met each other in a rotation cycle, their time progressed uniformly and they were bound by each other. As the cycle began to move away, until the next cycle, the time of the Outsider developed backwards, that is, twenty years later it returned to the beginning of the forty years of HellCity. The World, Kingdom continued to develop in a continuous present tense. It implies the tenacity of life in the Outsider, and the need for enough ability in the World to avoid or completely change or kill them.

Here, taking the main characters’ forms of existence in each 20-year cycle (end) as a starting point, a simple table is listed below:

序号（相遇周期） 现世（王国） 异界（冥城） 冥界时间表（40年）
之前 0年 （天空之子等）已经存在20年 之后
①第20年 ……被异界发现之前 海神：死（薨，出手），马修、希雅：生 40年
②第40年 国王：死，马修：假死（薨王，出手） 怛：生  
③第60年 王子：20岁 怛：假死（王子，出手） 第2个40年
④第80年 马修、希雅：再生 怛：死（希雅，出手），薨王：假死（马修，出手）  
⑤第100年 国王（王子）、王后（希雅）：死，新的王子：生 薨王：死，马修：“活”（宿命循环） 第3个40年
  • The 5 serial numbers represent five different cycles. Calculated by the World’s timetable, they are: the 20th year… and the 100th year.
  • The people of the Outsider have a resurrection cycle every 40 years. Note: In the second cycle, Matthew faked his death once.
  • Only people from the Outsider can be reborn; people from the same “world”, if killed by their own kind, will not be resurrected. Matthew is an exception.
  • The king (prince), following Matthew’s order – “kill” Matthew, to kill King Hong – was killed by King Hong.

Cloud City

The time of Kingdom and HellCity is in an early stage of development relative to Cloud City; Cloud City’s time is always at some point in the future relative to the World and the Outsider. See the novel “Cloud Country” for details.

Here just briefly mention: The people on Cloud City do not die because they have no bodies, only souls (mostly people from Kingdom who were killed by “the Outsider”). Of course there are exceptions, that is: The original people of the Outsider, if they die and go to Cloud City, may die again, experience reincarnation, and return to HellCity. (The mystery of Matthew’s origin)

The cycle of fate is only exclusive to the original people of the Outsider.
