Li Chengqian, Crown Prince of the Zhenguan Era

The beginnings were quite interesting; the protagonist and supporting characters were both intelligent. However, as the story progressed, things went wrong. Not only did some characters' personalities become inconsistent, but even the protagonist's character development and inner thoughts disappeared. The supporting characters' inner monologues were more complex than the protagonist's.

Without a cheat code, even an active-duty soldier can't outwit the strategists of the ancients, let alone outmaneuver them—that's pure fantasy. You enlisted at eighteen, you're already a top soldier, your education level isn't high, and you didn't study history; you were just trained to serve, obey orders, and follow the Party.

Are you sure Li Shimin would release a rebel based on a few words? He could kill his own son for rebelling, let alone outsiders.

An eight-year-old prince already knows so much, are you sure?

I suggest the author divide the text into paragraphs; it's too tiring to read like this.

I haven't read the book yet. But Li Chengqian's status plus his understanding of history... That's like having two kings plus four princes! The eldest son and crown prince, his mother was the empress, his teacher was Wei Zheng, and his uncle was Changsun Wuji. Although Emperor Taizong (Li Er) doted on Li Tai and Li Ke, his affection for Li Chengqian was no less.

If you transmigrate into the body of Li Qiancheng, as long as you don't do anything reckless and outlive Li Er, you'll be the emperor!

Is the protagonist a time traveler? I'm so confused! Doesn't the protagonist have any common sense like a modern person? Changsun Yue is a cousin, right? They're within the five degrees of kinship, aren't they? Marrying like that would be incestuous, and it would pose a huge risk to their offspring! Surely the protagonist knows this?

It's so good! Although it's a bit cruel to the protagonist, who is framed and can't fight back, loses his wife, and has his mother bullied and crippled... But what else can he do without a cheat code? Is good writing enough?

Li Qiankun is the easiest to obtain the throne. His eldest son and maternal uncle, Changsun Wuji, are destined to be emperor if they don't court death. You've already transmigrated, yet you're doing worse than the original. What's the point of watching you? Are you just going to suffer?
