Chapter Nineteen: Tremble, Durex and Okamoto!

Page (1/3)
Huo Qitai strained to recall. Since his rebirth, his memory and brain capacity had dramatically improved, almost like he had hyperthymesia. Everything he had experienced or seen in his previous life was now vividly clear.
“Although I held grudges against my eldest aunt in my past life and barely interacted with their family before graduating college, my mother once called me and mentioned something.
There was trouble in my eldest aunt’s family—Hui was deceived, and all their money was swindled away. Mom even urged me to find her at the Foreign Languages University, fearing something bad might happen to her...”
The memory surfaced, and Huo Qitai glanced again at the parents of the groom-to-be, Xie Hangyu.
Now he was even more certain: they were not a family at all, but a group of con artists working together.
“However, without solid evidence, if I rashly accuse my eldest aunt and Hui’s family of being fraudsters, they wouldn’t believe me for a second.”
The banquet began. One delicious Jian’an specialty after another was served, but Huo Qitai’s mind was preoccupied with how to help Hui.
After all, the eldest aunt’s family had always supported the entire Huo family, and Hui had helped him several times by leveraging her connections to introduce professionals during his entrepreneurial ventures.
Huo Qitai could never stand by and watch Hui fall into the fire again.
“Fortunately, Hui is quite traditional. In my past life, she said she was glad she insisted on chastity until her wedding day, or else it wouldn’t have been just financial fraud.”
Watching the family of fraudsters toast and speak with fake sincerity, Huo Qitai recalled some key memories and quickly formulated a plan.
At the same time, he remembered some other details related to Hui.
“Hui has a close friend in the capital named Chen Jingyi, a law student whose family has connections in the Trademark and Patent Office. She specializes in intellectual property and patent applications.
In my previous life, several of my company’s patents and trademarks were handled by her—fast and effective.
Perfect, I’ll have her handle the patent application for the color-changing condom and global patent protection. Reliable!”
Huo Qitai recalled a “brilliant” invention stored in his memory.
A color-changing condom designed to detect various sexually transmitted diseases—a British invention by high school students from the future.
This condom changes color upon encountering viruses, using antibody technology. When antibodies meet pathogens, the condom quickly changes color, with different hues indicating different STDs.
For example, green signifies chlamydia, yellow herpes, purple human papillomavirus, and blue syphilis.
This technology had received recognition from top international medical experts and institutions.

The three teenagers who invented this technology were awarded the Teen Tech Award for healthcare in the UK, and they were invited to Buckingham Palace to receive royal commendations.
In his previous life, the reckless Huo Qitai, who frequented many romantic entanglements, was most worried about safety.
So when he saw news about the color-changing condom, he became very interested and researched it seriously.
He even tried to contact the three British inventors to obtain patent authorization for mass production in China.
Unfortunately, it seemed they had disputes over profit shares. Not only was Huo Qitai unable to secure the license, even major international companies like Durex and Okamoto, despite paying high prices, failed to acquire the patent rights.
Therefore, this invention—capable of benefiting countless people—had not been practically applied before Huo Qitai’s rebirth in 2024.
This was another great regret in his past life.
He was nearly certain that if he could get the patent rights for the “color-changing condom” and leverage China’s affordable manufacturing, it would be like printing money.
And now...
He was back in 2010, with all the key technology and patent documents for the color-changing condom in his mind. He would no longer let this gem remain unnoticed; it must benefit humanity.
“Dear in-laws, our little Hui is truly fortunate to marry into such a kind family.”
“I heard you even prepared a wedding house for the young couple! Housing in the capital is expensive, you really care about them.”
…
The Lin family members were all eloquent, surrounding the groom’s family, toasting and chatting amiably.
Meanwhile, the Huo family sat quietly, eating their dishes. Only Huo Qitai’s father and aunt were pulled over by the eldest uncle for a brief toast and introduction.
“All right! All right! Uncle and Second Uncle, Hangyu and his parents aren’t good drinkers; I’ll drink this toast for them. No more after this.”
Lin Sihui inherited her mother’s bright and assertive personality; even before marriage, she was already shielding her husband from too much drinking.
Behind her, Xie Hangyu wore a smug smile, feeling he had completely won over Lin Sihui.
The banquet ended swiftly amid rounds of toasts.
As Lin Sihui was about to escort Xie’s family back to the hotel, Huo Qitai quietly approached and stopped her.
“What’s up, A-Tai? I heard you’ve been quite the playboy lately! Kissed two girls already, huh?”
Looking at his troublesome younger brother, Lin Sihui smirked.
Earlier at the table, Lin Yan from the Lin family had exaggeratedly tattled on Huo Qitai to Lin Sihui.
Huo Qitai didn’t deny it but smiled and said, “Hui, you’ve graduated college and gotten into grad school, why still so old-fashioned? Plenty of high schoolers are dating nowadays. Besides, I’m about to start university soon.”
“Yeah, yeah! Our A-Tai is handsome and charming; it’s no wonder girls are chasing you.
So, what’s up? You didn’t say a word during the toast; if you’re coming to me privately, it can’t be anything good.”
Lin Sihui knew Huo Qitai well. Having grown up with him as the eldest sister, she had often cleaned up his messes.
“Hehe! Hui, you understand me. I don’t come without a reason. I want to ask if you know any classmates studying law.
I’m in science! When I have free time, I’ve been working on some results in the school chemistry lab and want to apply for a national patent, but I don’t know how.”
Huo Qitai put on a shy high school boy act, speaking seriously.
“Huh? What could you possibly invent in the chemistry lab at our school?”
Though skeptical, Lin Sihui thought carefully and said, “I do have a close friend, Chen Jingyi. She didn’t continue to graduate school but works at a relative’s law firm specializing in patents and trademarks.”
“That’s perfect! Hui, can you give me her QQ? Maybe someday I can help you out big time too!”
After some coaxing, Lin Sihui gave Huo Qitai Chen Jingyi’s QQ and messaged her, explaining that this was her cousin.
“Mom, Dad! You guys go ahead. I have some important business at the internet cafe, so I won’t be joining you.”
Having obtained the QQ number, Huo Qitai wasted no time and headed straight for the nearest internet cafe.
“Hehe! It’s settled. The patent for the color-changing condom is mine. Tremble, Durex and Okamoto...”
Huo Qitai felt delighted inside.
