I actually cried during the angsty part going from the end of arc 1 to the beginning of arc 2. The first (and only) danmei that ever made me bawl. But it's HE! I swear!

MC died in the 'real' world (if you know what I mean), and woke up in the ancient times.

MC sleeps (he doesn't die nor does he grows old) every time ML leaves each world (dies in other word) and wake up every 600 years to find the ML and spend another life time with him... it doesn't get old I'm telling you, for each arc is REALLY REALLY NEW AND INTERESTING.

In the last arc though, MC slept for 3000+ years and woke up in the modern era, which is one of my FAVORITE. The other one being the arc where MC got cursed and became a puppy while the ML in the same arc is a (somehow) crippled prince. I was dying of cuteness while reading it (no worries, there are also s*xy scenes in this novel~).

Lastly, MC IS OP and the innocent yet cruel type (you'll know what I mean once you start reading).

This is very different from those novels with multiple lives as it progresses in same world but after hundreds of years of time leap and MC always has his own body and ALhpufh he has a low EQ, Iwe see him grow in character. He is super powerful and opposite to other novels where MLs always help MC, he is the one who always helps ML.

Also unlike other system novels there is no destined plot of the world , not are there missions MC has to perform, so it's unknown what MC will encounter next, And I love how MC Is so straightforward and innocent but at the same time cruel and very smart.

1:
they cutest and the saddest, because MC is kinda disappearing, make ML misunderstood that he hate ml, so ML die in sadness, but not before making policy so that male can marry another male, so paving path for the second world
2:
set 600 years after 1st world, MC still retain his memory, but ML just have some good feeling toward MC and extremely insomiac (he dream every single night from 3 years old), and there a monster that swallow and wear other people skin and raising terror upon the country, but even after heart got split by MC, she still manage to live (somehow even retain her memory enough to make trap to mc). But still caught in dog form (how?? What about her IQ??)
3:
MC still himself, but somehow ML is king of hell (how could??) that manage to ovethrow the previous king (he somekind of devil) and also the 5th prince (that got to became emperor soon)
feeling lazy because the back story of how they met again and again (the transmigration) is kinda lackluster and dissapointing, even though I love each story!! MC is pure and enchanting!
the truth what make me postpone reading this is because in 3 world, mc's white lotus character is kinda wiped away. I don't really enjoy reading kind and bullied MC : ((
i prefer to read MC bullying others!
