This made Su Ningning think of the world she lived in. Almost everyone on the street knew about something called "Watermelon Frost Throat Lozenges". Every teacher in the school prepared a box of them to carry with them. When the throat was uncomfortable, taking one lozenge was very effective!

But the origin of this watermelon frost throat lozenge is not simple. It was developed by a university professor named Zhou Jimin after spending eight years and experiencing countless failures.

Because if you prepare watermelon frost according to the ancient method, the volume will be very large, the process will be very complicated, the efficiency will not be high, and the storage time will not be long.

This requires the use of modern technology to extract watermelon frost and then make better tablets. Those seemingly inconspicuous throat lozenges that everyone can buy in later generations were made after countless failures.

Su Ningning had also heard that this professor named Zhou Jimin made great sacrifices to develop the watermelon frost throat lozenges. He was so poor that he couldn't even afford to eat because all his family property was invested in the development of medicinal materials. His wife even divorced him...

This is not the hardship that a person who concentrates on researching medicinal materials should experience. Su Ningning looked at the description of watermelon frost on the tree, her heart pounding. She thought, wasn't the reason she came to this book to change those bad things about her body?

For example, preventing He Qingshan's death, changing the tragic fate of those around her, and making everything better.

Then for a senior like Professor Zhou Jimin who is so respected and admirable, she should use her own strengths to help him!

If the Watermelon Frost Throat Lozenges could have been released earlier, Professor Zhou Jimin could have achieved his dream sooner, and could have avoided the grievances and sorrows he experienced during those eight years. So many people across the country would no longer be troubled by various oral and throat diseases.

Su Ningning sat in the library, and the more she thought about it, the more she felt that she should immediately write a letter to Professor Zhou Jimin, and tactfully help him avoid those inappropriate paths!

She was so focused that she didn't notice someone quietly passed by her and looked at the book she was reading.

After the female student saw the name of the book clearly, she quickly walked out of the door, wrote it down on her notebook, and then walked out of the school gate to the bus stop and took the bus to a place.

She found a house with familiarity and knocked on the door. Soon a woman with a scar on her face opened the door for her.

The moment she opened the door, she was startled, but thinking of what she had promised, she smiled and said, "I have been secretly asking what she is doing these days, the books she reads, the things she says to others, etc. I have recorded them all on a notebook, you can take a look."

The woman with the scar on her face chuckled, took the bowl, and said something that the female student couldn't understand.

"People who have lived two lives are different. They actually thought of watermelon frost. Haha, that's right. Watermelon frost hasn't been invented yet. If we can invent watermelon frost... wouldn't we be able to make a lot of money?"

In the past, she didn't understand why Su Ningning could win everywhere and always avoid the bad luck that was obviously destined to happen. Later, she finally figured it out. So many combinations were not real combinations. There was only one answer, which was that Su Ningning had also lived two lives!
