At one point early on the protag is trying to recover his core (dantian?) which was stolen by the antagonist. He's managed to cripple the antagonist, but when he is about to complete the job, two women that tried to kill him interpose themselves to protect the antagonist. Well shucks thems r girls can't hurt them.

This is a recurring theme of the protagonist hurting himself for people that would kill him as soon as look him

In the beginning, he is just a quiet 'bodyguard' and teacher for the MC, enduring humiliation from the so-called family; a reserved person. MC is also young and weak then, but she's trying hard to get ML to open his shell. As stated by the author, at this stage, the mood of the story is relaxed and happy.

In the middle part, when they went back in time to the Middle Ages, that's where the emotional development part is being displayed. I can read the despair and tiredness of the ML between the words, the 500 years of losing MC. In the same way, MC's emotional changes in the void space really touches me as well. Both of them really suffered. But it was also due to this suffering that both of them obtained the power needed to protect themselves. That's also when they realized their attraction towards each other.

In the final part, as the author put it, it's all about their inner struggle. ML with his inner demon and MC with choosing between her responsibility for the world or ML. Coming this far, you will see how ML's character has changed; from quiet to being able to flirt with the MC. It's a joy to see the emotional and character developments of them all.

I also like the concept of cause-effect and time travel and time merge in this story. In the 1st timeline, the ML really suffered 6000 years before meeting MC. While in the 2nd timeline/the current one, the ML waited a total of 900 years. It's a miracle the ML hasn't gone completely crazy. He's really a hardworking and responsible Emperor who shoulders way too much, especially when it comes to slanders from the demon world (that gang of brain-dead creatures).

• Ye Zhongyu - delusional, unrepentant, a freaking joke, 'everybody is wrong only I am right', 'heaven is unfair to me alone', 'I deserve all the good things in the world', 'everything should revolve around me'. OMG, I hate him so much!!! Non-recyclable tr*sh!!
• Su Yinyue - a dragon who abandoned everything for someone who doesn't love her and she knows it but she still does it. Like gurl, why?
• Yun Menghan - delusional, love-brain, brain-dead, another joke. She's a real cao/grass masochist. Even after all the humiliation by Ye Zhongyu, as long as he says he loves her, she's happy and willing. Can't take people's opinion that what she thinks is love is not really love. An expert in finding excuses for the scum, all because of love. Wishes all guys to love her and think it's an honor to have all girls jealous of her. Seeing that the book MC initially read is from her perspective, truly, it's because she's the dumbest character in the world, thus the memory can be safely extracted without alerting the owner of the memory. Truly a joke. (But honestly, this type of person really exists in reality, I know one, just not as chronic as this one.) The only shuang/cool part is when she finally stabs the scum. Like hallelujah! Finally! But seriously though, it takes her 2 lives to be awake. Sigh...

My only grievance is that the novel does not give more detail on what the final condition of ML parents. The novel only mentioned that they are in house arrest somewhat. But I want to read their regret.

There were many scenarios where I was like WTF. These two below take the top.

She is shown to have a playful character where she likes to read some dirty novels and such. This was fine, it added a comedy aspect. But her actions are too weird where she acts as though she is so uncomfortable holding his hand and hugging is also a BIG thing for her.

At this point, the ML and FL will both realize that they like each other although they dont confess. The ML will fight his father to get the patriarch position and before that he is also said many hurtful words by his parents. He falls down after the fight and the FL goes to pick him up. She gives her hand and pulls him up, he will be bleeding all over and wont even be able to stand up. Then she asks him how he is and keeps thinking about why he is still holding her hand and thinks if he says he is fine then she can take her hand back? WTF. The ML whom she loves is hurt physically and mentally and is not even able to stand and all she was thinking was why isnt he letting her hand go? Do normal people behave that way?

The second scenario was in the extras where they are already married and she wakes up after 6000 year long deep slumber. The ML takes her back and takes care of her. She will be awake after 6000 years and her body wont be good so he wont do anything physical to her. But she starts thinking that he might have been with other girls and might not be interested in her body. I was like WTF? The ML always keep searching for whenever she goes missing, which is a LOT. The ML also learns time and space for 100s of thousands of years just to come back to meet the FL. He has done so much for her and she is worried about him having affairs? There was no trust at all.

The ML and FL would have already started dating at this point. The FL is taken to the original timeline by mistake where the ML is already an emperor of heaven and she is taken hostage. She had no plans to stay in this timeline, she will always want to go to her original timeline and she keeps telling the ML this all the time that her lover is waiting and she has to go. Then she totally forgets about him and starts behaving as if he is her boyfriend in this lifetime too.

Initially it was ok. But later the ML in this lifetime too starts liking her and SHE UNDERSTANDS THIS. But she still doesn't fix her behavior and keeps hugging him and touching him and even tries to undress him once. He doesnt have anyone with him and she knows this, and starts behaving like his girlfriend behaving like she cares about him and makes herself a priority in his life. Why the hell was she going and disturbing his life to leave him alone in the end and go back ? I was beyond speechless, she was super selfish is her behavior. Always thinking about herself. Never once did she think about him.

In the end he locks her up and then lets her go after she starts fasting which was s*upid because they dont have to eat food to survive. She keeps telling him she will come back to find him. If she comes back to find him then what about her real boyfriend in the other world? Although it was tied up in the end. The whole concept dint make any sense when she says this.

The plot is also boring after the first time she travels away from the ML. I wasn’t expecting a heavily romantic story, but I absolutely hate that the best way the author thought of to expand on the ML’s abandonment issues is for her to literally abandon him for hundreds of years. And the MC is so s*upid, that when she travels into the future and meets a different version of the ML, she treats him with kindness she knows he’s never encountered and is so surprised when he doesn’t want her to leave.

Like how do I know her man better than she does? Because I knew he would behave that way, as its quite obvious based on his character.

there is no omniscient narrator. In fact, 'future history' is just from the perspective of one, very biased character

Keep reading with an east heart! He gets his happy ending!
