I Alone Level-Up - Chapter 5

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

Bei Ran lay on the operating table, Gu Qingchen was her surgeon. His eyes, deep as the Aegean Sea, gazed at her: “Honey, it's been four years since we got married, and you're still afraid of me?”Honey? Last night he already threw a divorce agreement at her, what right does he have to call her that?In City A, Gu Qingchen is a long-lasting legend. He is a leading figure in the medical field and a major shareholder in a Fortune 500 company, capable of great influence in the business world.He only needed an obedient wife. Bei Ran was so 'obedient' that he never had to worry. The four-year marriage was just a matter of agreement, but who is the one lingering endlessly after the divorce?She accidentally fell into water at a wedding she was hosting, he said: “Beg me, you know I'm always responsive to your demands!”“Gu Qingchen, we're divorced!” Bei Ran couldn't stand it anymore!He laughed coldly: “Bei Ran, we've been married for four years, you have a five-year-old daughter, do you really want to die here?”Bei Ran was shocked, he knew? Would he fight her for her daughter?Gu Qingchen could never have imagined that the chubby little bun in front of him was actually his biological daughter!“Bei Ran, you hid it from me for five years, always flawlessly obedient before me, tell me, how should I punish you?” Gu Qingchen raised a bloodthirsty smile.Could she possibly not tell him there is also a son who looks just like him!Theater Version:The teacher informed Bei Ran that her son had used a scalpel in school to investigate the cause of death of poisoned small animals. Her daughter was causing a stir in school with her stock trading. In her anger, she said, “No one to take you to school today, take the bus yourselves.”The daughter sought help from Gu Qingchen but got no response, so she said: “Yesterday, a pretty aunt stayed in Dad's office for an hour, and her skirt was super short.”The twins truly had a shared understanding; the son said: “The station manager hugged Mom yesterday, even kissed her cheek, and said he would never let go!”Bei Ran and Gu Qingchen spoke in unison: “Trying to sow discord, you're still too naive, go to school yourselves!”The siblings shouldered their backpacks and went to take the bus, while the couple returned to the bedroom, closing the door behind them.She leapt onto him, her fiery temper on full display: “You actually stayed with that woman for an entire hour?”He was overbearingly domineering: “Damn it, which part of you did he kiss, I will seal his mouth with a scalpel!”

In the late years of the Daqian era, tyrants roamed freely, war erupted endlessly, and the people could not sustain their lives.After transmigration, Chen Jie finds himself as a drunken gambler with a pair of unfortunate sisters at home.The elder one, Su Yunjin, is his wife, and he also has a five-year-old sister-in-law, Su Yunrui.Their family is so poor they can barely make ends meet.Then suddenly, his beautiful wife comes smiling, bringing him a bowl of hot porridge.“Husband, I was wrong yesterday. Please have some porridge while it's hot.”Seeing the bruises on his wife's face, Chen Jie feels something is amiss.Ding~[Daily Information has been updated][1. Yesterday, you gambled away the last three acres of good land, beat Su Yunjin while drunk, and planned to sell the five-year-old Su Yunrui, to recover your losses.][2. The Su sisters rely on each other. Su Yunrui is Su Yunjin's only hope.][3. Su Yunjin, having lost hope, traded her mother's hairpin three days ago for a pack of arsenic.]...Arsenic!Staring at the hot porridge brought to his lips, Chen Jie looks up at his wife, seeing the faint bruise on her face and her eyes shifting away, avoiding his gaze.“Honey!”“Yes?”“You're not going to kill me, are you?!”
