There is no harem in this
There is nationality in this
At chapter 1400, the main female leads "awakes" and leaves MC for over a thousand chapters.
The MC hasn't found her yet, nor has he become an immortal, so we have the MC chasing the female lead for over a thousand chapters.
The MC personality is annoying. He doesn't kill and this always results in his enemies coming back to hurt his loved ones. Sometimes, some of them nearly dies and the MC never learns.
The MC is also weak and somehow on this earth, where nobody is supposed to cultivate, there are powerful and rich families who are cultivators.
they going around throwing billions of dollars and using their cultivation powers to brainwash people. Not to mention that there is also a huge island with people who are half-step immortals.
chapter 150 is when he sleeps with a woman for the first time in the novel, but it's just a fling. later on however, he manages to brainwash the girl into being okay with being his concubine (not mistress) and marries another girl. he also hooks up with another girl...
he has..6 children I think, at chapter 300.
ironically and very realistic, all of his women + children leaves him once the war starts except for one, but he quickly picks one more up from his planet's universe.
so much for being loyal to a man who cant be loyal
however around chapter 150 the cause of destruction in the planet is slowly unravels and at 250, he finds proof of the aliens.
when the aliens finally attacked, the humans decided to start a "tournament" style "war" every few years instead of just kicking out the invaders.
also the aliens turned out to be humans who moved to a planet where they can cultivate, so it became a xianxia novel and earth is slowly creating it's own "qi". science is also slowly changing and all modern weapons slowly become worthless while cultivators become more and more powerful over time.
the author writes that since the "qi" is weak, it is the best time to kill them all and we already have robot soldiers on earth but nope. earthlings will be joining this tournament every few years while the alien cultivators slowly wait and will enslaves us all once the "qi" has recovered.
everything was part of a plan to create a proper world government so that space exploration and that the defense of the earth is possible since again, he is preparing for aliens to attack earth due to the parallel universe (but in the end it is cultivators who attacked earth....)
so continuing from where I left off.
humans basically lost for several decades and "surrendered" all of their planets and space ports except mars.
BUT although humanity lost everything, the aliens lost more. because the cultivators fought with their bodies while humanity used mechs and the cultivators decides to just end it all and started to attack humans again. but humanity used their newly upgraded nukes to nuke all the cultivators.
then the cultivators who were at a loss, called one of their saints to help. this saint used this two hands and squeezed several planets into dust (but not earth).
MC answer was to send a black hole bomb + 10, 000, 000, 000 nukes and bomb this saint to death. peace occurred.
fast forward a few years, the MC decided to "integrate cultivators into humanity" (yay!)
but remember that the cultivators has a few more saints? well the answer of how to make sure that the saints do not do disagree is to bury 100, 000, 000, 000, 000 nukes on all of the planets that people are living on and say "i'll detonate if you disagree"
so MC goes to this xianxia world, he randomly walks into a cave and finds a cultivation technique (i sh*t you not).
he then goes to a village and it so happens that there is a sect reciting. he joins the test and he passes it... and joins it... (remember at this point the MC is probably a few hundred years old but whatever, he passes the test)
apparently clone/avatar techniques are trash in this world and he gets one the second he joins the sect. he makes a clone and sends to his world and teaches some members of his family the techniques he learnt.
back to the xianxia world world, he then goes to gamble and win tons of money. he buys more cultivation techniques and uses ai to make his own cultivation technique.
he later finds that this guy was captures and tortured for billions of years because of power struggles in the clan. No shit. You left all your weapons and stuff in the cave so durh
For example, he threatened to wipe out the demon race in front of the demon king who he can only run away. He is clear that he cannot win but still he does it anyway. He also raped one girl and immediately said he didn't want to take any responsibility. Funny because it was the same thing that happened with Su Yan but he wants Su Yan so badly vs this girl who has done nothing but help him. Later one he also tries to rape another girl and only stopped after she threatened to break his dantian.
This MC isn't the same guy you read in the first 700 chapters anymore. He becomes utter trash for no reason. High realms also keep on popping out for no reason and the novel drags on to 4000+ chapters when it should have ended around 1800
