[Adorable child + parallel timeline + not entirely historically accurate + not a pure power fantasy]
He Jin, a wage slave in the 21st century, has an odd conversation with his mother over the phone after staying up all night to finish work.
He Jin's mom: "When are you going to start dating?"
He Jin: "I'll... let you know..."
He Jin's mom: "At your age, if you don't have a kid soon, it'll be too late!"
He Jin: "By... next Wednesday at the latest."
He Jin's mom: "You @#¥!%..."
Before he can process what happened, one cup of coffee shatters his wage-slave dream on the spot. He has no choice but to head home, only to get sent off by a "non-smiling dump truck" on the way.
When he opens his eyes again, he's an all-powerful immortal in another world.
He wants to lie flat and be a lazy fish, but then he meets an adorable two-year-old.
Little Sizhi: "Immortal, can you get my kite down for me?"
He Jin: "Call me big brother. Also, this kite can fly on its own. Don't tell anyone. This is a secret between you and me, Sizhi."
From that day on, He Jin becomes the personal deity of the little Princess Jinyang, Li Mingda.
She wants to eat the clouds in the sky, so he makes her cotton candy. She wants to see snow, so snow falls in the imperial garden in June. She misses her father, who's away on an expedition, so he uses a water mirror spell to livestream him.
Until one day, Li Shimin and Empress Zhangsun witness He Jin manifesting his divine power with their own eyes.
Little Sizhi hugs him around the neck and introduces him proudly:
"Father, Mother, this is my immortal big brother!"
From then on, He Jin's immortal life includes one more activity.
He stares expressionlessly at the emperor, who has come by "for a visit" with his little sister in his arms.
"Just tell me what you want."
I'll give you three stars. Let's not talk about history. The protagonist's time-travel mentality is not in line with the values of the current society. I didn't react at first, so I just felt very uncomfortable watching it. I have read so many time-travel novels. You are the first one to tell the protagonist that he had contacted his family before time-travel. But after time-travel, he only had the feeling of indifference you wrote, and the dump truck that hit him still had filial piety, which was very disconnected. And how could Xiao Sizi call himself Xiao Douzi? What's the difference between this and sensationalism? I haven't watched it since, I really can't watch it anymore.
