He had just married a policewoman when he was diagnosed with criminal genius.

Several people gathered around.

"Film green and Meniere white?"

Tang Sancheng spoke first, his tone full of suspicion, "Director Ding, where did this thing come from?"

"Never mind where it came from, let's give it a try first," Ding Jianguo said calmly.

Old Chen took the note and read it several times. His expression gradually changed from doubt to contemplation: "Film green ink... Meniere white... I feel like I've seen this ratio somewhere before..."

"You've seen it?" the skinny man beside him urged. "Think quickly!"

Old Chen scratched his sparse hair and suddenly slapped his thigh: "I remember now. More than ten years ago, I worked with a retired master craftsman from a mint in the south. He had a few drinks and mentioned that the key to the real color-changing ink lies in the ratio of these two pigments."

Old Chen paused for a moment, then continued, "But he said it's top secret, and no one can get the exact proportions."

Tang Sancheng, standing to the side, looked at Old Chen strangely: "So you didn't do any more research after that?"

Old Chen chuckled awkwardly, "Of course I've researched it, but I've found that if the proportions aren't right, the color is too different from real color-changing ink, making it unusable, or even close to it. Only by knowing the precise proportions can you make real color-changing ink."

"So I later chose other pigments to mix and gradually forgot about it."

"What's the proportion on this piece of paper?" The kind-looking middle-aged man leaned even closer.

Ding Jianguo slammed the note on the table and pointed to the last line of small print: "Mix film green ink and Meniere white ink in a ratio of 3.7:1.2 per 100 grams, with the addition of trace amounts of stabilizer."

The four of them remained silent for a few seconds.

"How so?"

"Give it a try."

"What if!"

"Okay, let's give it a try."

After a quick discussion, the group decided to get started immediately.

"Then go ahead and try. Remember, you're here to earn a reduced sentence through meritorious service, so don't waste the opportunity." Ding Jianguo stepped back to a place where he wouldn't get in the way and personally watched them mix the ingredients.

Once the work officially started, the factory immediately fell silent.

Soon, the prepared ink samples were placed on the table.

The light green liquid, gleaming with a faint metallic sheen under the light, lay quietly in the experimental beaker.

"This color..." Tang Sancheng was the first to break the silence, his voice tinged with disbelief, "It seems rather interesting."

Old Chen was an impatient man: "Whether it is or not, we'll know once we try."

He then carefully picked up a glass rod, gently stirred the ink, and then lifted the tip of the rod.

The ink dripped slowly onto the prepared acid-free paper.

Under the light, the drop of ink shimmered with a pale purple halo, which then subtly turned back to green as the angle changed.

"A light-changing reaction!" the skinny man exclaimed, his voice rising an octave. "There really is a light-changing reaction."

Then everyone gathered around and compared the color of the drop of ink with the color of real ink.

"Wow... such an amazing similarity, at least 95% similarity."

Hearing the exclamations of the others, Ding Jianguo, who was watching from the side, was filled with shock.

I never expected it to actually work.

The formula Lu Chen provided actually worked.

These are the color-changing inks formulated by people who have spent half their lives, or even a lifetime, researching counterfeit money.

Lu Chen glanced at it and casually gave a formula, and he produced a color-changing ink with such a high degree of similarity.

Lu Chen said he had studied how to make banknotes during his university years.

Just how far has his research gone?

This is too incredible.

Could it be that Lu Chen is a genius at making counterfeit money?

Ding Jianguo was completely baffled.

"Director Ding, this ink is far superior to the new counterfeit banknote ink that has just appeared."

Ding Jianguo nodded, his gaze returning to the cup of gleaming ink.

"With this ink, how long will it take you to produce banknotes that are better than the new counterfeit banknotes?" Ding Jianguo asked again.

After pondering for a moment, Tang Sancheng slowly said, "The problem of the color-changing ink has been solved, saving us a lot of time."

Tang Sancheng then held up one finger and said, "I estimate we can complete the mission in a month."

Ding Jianguo's newly ignited hope was extinguished once again.

A month is too long. Even if they manage to catch this criminal gang in the end, Jiangbei City will suffer enormous economic losses.

At this moment, Ding Jianguo felt that these people were not as useful as Lu Chen.

After all, Lu Chen solved the problems they couldn't solve with just a few words.

Ding Jianguo felt that instead of waiting for these people, it would be better to let Lu Chen take a look, which might speed up the production of counterfeit money.

"One month won't do!" Ding Jianguo refused decisively.

"But we really can't finish this in a week!" Tang Sancheng said with a bitter face.

The other three echoed this sentiment, stating that the mission was impossible to complete.

"Let me think of something!"

Ding Jianguo turned and walked towards the door. Soon after, he heard the crisp sound of experimental equipment colliding behind him, as well as the excited discussions of several people in hushed tones.

……

That evening, Sun Dazhi booked a private room at the best restaurant in Jiangbei.

Upon meeting, Sun Dazhi's first words were: "Brother Lu, I absolutely love this script."

Sun Dazhi excitedly flipped through the newly printed script, saying with great delight, "You absolutely have to make this script into a film. The price is negotiable; I promise you won't lose out."

Lu Chen picked up his teacup, took a sip, and said, "I'll hand over the script to you. As for how much money you'll pay, you can decide."

Sun Dazhi was overjoyed when he heard that Lu Chen had given him the script.

Although Lu Chen said that he could decide how much to pay for the script, Sun Dazhi didn't dare to give it away casually.

Putting aside how excellent Lu Chen's script was, the fact that Lu Chen's script solved his immediate problem and helped him raise support from the Xia Kingdom Film and Television Bureau made Sun Dazhi extremely grateful to Lu Chen.

"As for the price of the script," Sun Dazhi paused and said, "I discussed it with the producer, who is also our investor, the Xia Guo Film Bureau, and they are willing to pay three million for your script."

Three million?

Lu Chen was stunned; he hadn't expected a script to sell for three million!

What else is there to say? I agree!

Just as Lu Chen was about to agree, Sun Dazhi spoke again.

"They're lowering the price because they think you're not qualified. If you were a well-known screenwriter, your script would cost at least five million." Sun Dazhi said helplessly.

"However, I was not satisfied with the price they offered, and in the end they agreed to include one percent of the box office revenue in the script purchase contract."

"One percent of the box office?"

Lu Chen was already quite satisfied with the three million yuan script fee, but he didn't expect that Sun Dazhi was dissatisfied instead.

"Yes, one percent of the box office. Brother Lu, don't underestimate this one percent," Sun Dazhi's eyes gleamed. "One percent of the box office means that if our movie grosses one hundred million, you can get another one million in royalties."

"I have a lot of confidence in our script. It should be able to help you earn at least a few million more," Sun Dazhi assured, patting his chest.

"Okay, we'll do it your way." Lu Chen put down his teacup.

"By the way, Brother Lu," Sun Dazhi suddenly leaned closer and lowered his voice, "there's something I'd like to discuss with you beforehand."

"you say."

"I want you to play the villain 'Manager Lu' in this film." Sun Dazhi looked at him seriously: "I know you have no acting experience, but I have seen your talent with my own eyes, especially the commanding presence you exuded in the promotional video, which is a perfect fit for Manager Lu."

"Besides, you wrote this script, and no one understands the character better than you."

Lu Chen was silent for a few seconds, then slowly nodded: "We can give it a try."

"Great!" Sun Dazhi slapped his thigh, his face beaming with joy.

"Then let's start preparing tomorrow. I'll contact a few reliable photographers and lighting technicians first, and then see if there's a suitable venue."

Lu Chen nodded: "The filming location must be authentic." Lu Chen's eyes became serious. "The accuracy of the recreation of the fraud factory will determine the impact of this film. If possible, try to find an abandoned factory and set it up like a real fraud park."

Sun Dazhi nodded repeatedly, "I've got it. This will be my directorial debut. If I'm going to do something, I'll do something big."

"I'll contact you again when I'm ready to start filming."

Although Sun Dazhi was anxious, he also understood that the pre-production preparations for filming a movie could not be taken lightly.

Besides finding and confirming filming locations, the director also needs to oversee the casting.

Lu Chen raised his glass: "Then let's wish each other a pleasant collaboration."

"It's a pleasure working with you."

The two cups collided in mid-air, making a crisp sound.
