Qin Di walked in and looked and found that the furnishings in the house were very simple. There was a woman lying on the bed and she had no breath.

He walked up, covered the woman's head with a quilt, and said, "Yan Xue, you are waiting here, I'll go find a coffin."

Then, he walked out and left Yan Xue standing beside the bed in a daze.

In less than half an hour, Qin Di took advantage of the night and walked back alone with a coffin.

He put the woman in the coffin, then held the coffin with one hand and a shovel in the other hand, and walked to the deserted slope of the mountain.

That night, the moon was like a disk, and the moonlight sprinkled on the ground like water.

Qin Di looked up at the distant mountains and walked two or three miles along the base of the mountain before finding a place with good feng shui.

Yan Xue held up the torch, watched Qin Di dig a big hole, put the coffin in, then piled up the grave with soil and stones, and erected a stone tablet in front of the grave.

There was not a single person around. The autumn wind blew, blowing on Yan Xue's body with a cool feeling. Looking at the grave, she felt very sad. Seeing Qin Di, she felt a little peace again.

Qin Di's fingers stroked across the stone tablet, making a "chi chi" sound.

Soon, the words on the stone tablet were engraved.

Yan Xue was shocked and knew in her heart that this "brother" was not an ordinary person.

Then, Qin Di took her all the way east and returned to the Demon City.

Zhu Wan was surprised to see her son bringing the little girl into the house: "A Di, where did this girl come from?"

"I picked it up from the road!"

"You kid! You just talk nonsense! Can you pick it up at will? Could it be that you were kidnapped by you? The parents are not in a hurry?"

"This girl's name is Yan Xue. Her parents are gone, she is just an orphan."

"Really? She has no other relatives? She has no uncle, aunt, aunt, grandfather, or grandmother?"

"Mom, don't ask! Wouldn't it be nice to keep her and treat her as multiple daughters?"

Zhu Wan was amused and crying: "If I want my daughter, I won't choose it myself? I still want you to help?"

She is a professional woman, not a woman who never leaves the door. She walks on the street every day and is used to the tragic phenomenon of selling her children and daughters. She doesn't know why her son is very kind and brings the little girl home.

She called Qin Di aside and asked in a low voice: "A Di, tell me honestly, what do you think? Should I keep it as a child bride? Is it too young?"

Qin Di said: "Mom, you're thinking wrong! This girl is very unusual, she is the apprentice I found."

Zhu Wan snorted: "You are so young, what apprentices can you accept? What can you teach them?"

"Mom, why are you nagging so much? The Qin family is not without money. Can't you afford to support a little girl? If you object, I will move out!"

"Okay, okay, I recognize this daughter, can't it be okay? This child is not ugly."

Since then, Yan Xue has lived in the Qin family.

Qin Di told her a mantra of breathing and breathing, and then sent her to elementary school.

Qin Ling and Qin Yue were both curious, but they were kind-hearted and did not reject Yan Xue.

Qin Hancheng turned a blind eye and didn't care about the extra mouth at home.

After all, it is a wealthy family. The donations given out every year are tens of thousands of oceans. Raising an extra girl is considered to be a charity.

However, Yan Xue knew very well that she was bought by Qin Di and was not the young lady of the Qin family.

In 1918, Qin Di was 18 years old and officially became an adult.

Up to this time, as the exclusive magic medicine, sulfonamide medicine quietly made money for five or six years, but gradually could not hide it.

Some spies went to Chongming Island and kept scouting outside the pharmaceutical factory, wanting to sneak in and find the secret.

Although Qin Di hired a lot of guards, patrolling three shifts, and defending them very tightly. But gradually, even the guards were bribed.

So, he had to prepare for the future and consider applying for a patent.

He first consulted his grandfather Zhu Mingcheng, and then on January 1, he met Wallace, the dean of the School of Law of St. John's University, an American lawyer.

After some conversation, the two parties signed a letter of attorney.

Qin Di paid 18,000 US dollars and hired Wallace as his attorney, and applied for patents in the United States and the United Kingdom in the name of his mother Zhu Wan.

He then waited patiently for more than half a year until September when Wallace told him that the patent application was accepted, and he sent a series of papers to the British Medical Journal, the Lancet, Nature, and the American Siene and the New England Journal of Medicine.

From November 1918 to May 1919, in just half a year, twenty-two papers signed by "Zhu Wan" were released at once!

"The Synthesis of Oriental Magic Susadiazine", "Preparation of the External Drug Susalate", "Study on Pharmacokinetics of Susadiazine", "Clinical Experimental Effects of Susadiazine", "Silver Susadiazine Inhibits Staphylococcus aureus"... "Catalotypic Synthesis Method for Aspirin Citric Acid", "Aspirin Carbonate Synthesis Method"... "Aspirin Potassium Hydroxide Synthesis Method", "Aspirin Sodium Acetate Synthesis Method"... "Aspirin Pyridine Synthesis Method", "Aspirin Sodium Benzoate Synthesis Method"...

So many papers were released suddenly, and the whole world was shocked!

"Oh my God, the 'Oriental Magic Medicine' that has always been mysterious has finally been unveiled!"

"I didn't expect that this pearl in the history of medicine would fall on the heads of the Chinese!"

"How can a poor and backward China give birth to a brilliant civilization? This is simply a miracle!"

"It's incredible! This is an epoch-making contribution to mankind..."

It was not until this time that people suddenly learned that a shocking scientist was produced in the Magic City, and a female doctor who was engaged in clinical work!

When the news reached the Demon City, Zhu Wan was shocked first, caught her son and asked, "A Di, why did you push me out? These things are all your achievements! They have nothing to do with me."

Qin Di smiled and said, "Mom, you have worked hard for half your life and should enjoy the days of being respected."

Zhu Wan said: "What do I want this false name to do if I have half of the people who have been buried in the soil?"

Qin Di laughed and said, "Mom, you are still young! Why are you half-drunk? You still have a degree from St. John's University! And what about me? I haven't attended school for a day. If I sign my name, it will make people expose my old story and make a big fuss!"

Zhu Wan had a bitter face: "A Di, you put too much pressure on me! I'm afraid I'll be kidnapped when I walk on the road!"

Qin Di comforted her and said, "As the saying goes, there is a saying. Those kidnappers like to kidnap corrupt officials. You are a famous medical scientist and will only make countless Chinese people admire you! Don't worry, no one will kidnap you."

"That's not necessarily! If I had known this, I would rather you not publish a paper."

"Mom, how can this supreme reputation be given to others? This is our contribution, the achievements of the Zhu family, and the pride of the Chinese people!"
