However, Shen Qiqi did not rush to use these substitutes, but improved them.

She ground, screened, and mixed the materials, and the series of operations were so smooth that Lu Qing was dazzled.

"Qiqi, what are you doing..." Lu Qing couldn't help but ask.

"Improve it!" Shen Qiqi answered without even looking up, "It definitely won't be that effective if used directly. We need to optimize it to maximize its potential!"

When people around knew that Shen Qiqi was going to use substitutes for production, they expressed their doubts and felt that Shen Qiqi was having wild ideas and was simply dreaming.

Second Sister-in-law Lu even sneered, "Hey, Third Sister-in-law, don't lose all your family fortune! Don't cry when the time comes!"

Shen Qiqi turned a deaf ear and concentrated on conducting her experiment.

Time passed by minute by minute, and the air was filled with tension.

Lu Qing held Shen Qiqi's hand tightly, giving her silent support.

Finally, after some hard work, the improved material was born!

Shen Qiqi looked at the finished product in her hand with a confident smile on her face.

She tested the improved material and the results were surprisingly good, with all indicators exceeding expectations.

"It worked!" Shen Qiqi jumped up excitedly and hugged Lu Qing, "We succeeded!"

Lu Qing hugged Shen Qiqi tightly back, his embrace was hot, and an ambiguous atmosphere filled the air between the two.

Shen Qiqi leaned in his arms, sweet emotions overflowing in her heart.

In the study, the dim light shone on the two people, stretching their shadows out.

Lu Qing looked at Shen Qiqi. He gently held Shen Qiqi's face and kissed her affectionately.

After a long time, their lips parted.

"Qiqi," Lu Qing's voice was low and hoarse, "You are awesome."

Shen Qiqi winked playfully, "Of course, don't you see who I am!"

The news of the successful improvement quickly spread throughout the Lu family, and those who had laughed at Shen Qiqi were now speechless.

Shen Qiqi's heart was filled with pride. She knew that this was just the beginning...

"Next..." Shen Qiqi looked at the materials in her hand meaningfully, with a mysterious smile on her lips, "This is the real show!"

Shen Qiqi worked tirelessly to put the improved materials into technology research and development.

She was like a tireless little motor, busy in and out of the laboratory. Various experimental equipment seemed to come alive in her hands, making a pleasant "ding-dong" concerto.

A few days later, good news came!

The improved materials have perfectly solved the technical problems, and all indicators have far exceeded expectations!

"It's done! It's done! I'm the best in the world!" Shen Qiqi jumped up excitedly and hugged Lu Qing beside her, her excitement beyond words.

Lu Qing staggered when he was suddenly hugged by Shen Qiqi, but seeing her smiling face, he was also very happy.

He rubbed Shen Qiqi's hair lovingly, "I know that my Qiqi is the best!"

The news of the successful research and development spread quickly throughout the Lu family like wings.

When Mrs. Lu heard the news, her face turned uglier than if she had eaten a fly. She said sourly, "Humph, a blind cat catching a dead mouse, what's there to be proud of?"

Shen Qiqi didn't bother to pay attention to her sarcasm. She just wanted to quickly launch the product to the market and let those who once looked down on her see her strength!

However, at the critical moment when technological research and development achieved a breakthrough, a huge problem was placed in front of Shen Qiqi - the capital chain was broken!

In order to develop new technologies, Shen Qiqi and Lu Qing spent almost all their money, and now there is not enough money on the books to carry out the next step of production and promotion.

"What should I do? Is it going to fail at the last moment?" Shen Qiqi bit her fingers anxiously, her brows furrowed, like an ant on a hot pan.

Lu Qing comforted her, "Don't worry, Qiqi, we'll think of a solution."

"What else can we do?" Shen Qiqi sighed, "The only way now is to take out a loan, but..."

Lu Qing also understood that getting a loan was not an easy thing in the 1970s.

With a try-it attitude, the two went to the bank in town and submitted a loan application.

However, as expected, the bank rejected their application on the grounds that the risk was "too high".

The bank staff impatiently threw the loan rejection notice in front of them and said, "Alright, alright, stop wasting time here and leave!"

Shen Qiqi and Lu Qing stood at the bank door holding the bank's loan rejection notice. The cold wind made them shiver...

"Now...what should I do?" Shen Qiqi muttered to herself.

Lu Qing took a deep breath, his eyes determined, "There will always be a way..."
