Luo Feng was reborn back in his high school years. From the start, he acquired the Return On Investment System.

[Invest in this coffee shop and you will be able to open many branches in the future. It has an ROI of 100%.]

[Invest in Bitcoins and the price will skyrocket in the future. It has an ROI of 10,000%.]

[Invest in the cute girl who is the deskmate in class and she will become your wife in the future. It has an ROI of infinity.]

Luo Feng decisively chose to invest in his future wife.

Many years later, during a press conference, a reporter asked, “Mr. Luo, your White River Investment Company has surpassed Morgan Stanley and Goldman Sachs, becoming the most famous investment management company. In your opinion, what is the most successful investment you have made in your life?”

Luo Feng looked at his wife fondly as he replied, “Don’t ask me. I just live off my wife.”

First of all, this is not a story where the cannon fodder chambermaid counterattacks and gives the main wife a beat-down! As a lowly s*ave who had been sold a total of six times, Xiao Hua has long become apathetic to her situation. In her past life, she was a cannon fodder chambermaid who was beaten to death. In this life, she decided to turn over a new leaf and live honestly, yet in the end still ended up being sold off. This prince’s estate seems to have pretty good benefits? She could be released at twenty-five, and they’d arrange a place for her to live under their jurisdiction? They’d even get rid of her s*ave records? Great! That’s great! Xiao Hua thus decided to stay in the Jing Prince Estate and do her job properly. It’s a shame she could never overcome the whims of fate…. The master she serves is a “mute boy”, with several influences above him watching like tigers eyeing their prey. To say she doesn’t want to be pampered is definitely a lie. This is the road to survival of a “discreet girl” who clings on to her master’s leg and is solely pampered, yet feels that he never pampers her. The road from a cannon fodder chambermaid to a beloved imperial consort is a little long….
