At the beginning of the lanterns, the traffic and pedestrians on the street are bustling, but none of this has anything to do with the State Key Laboratory of Biopharmaceuticals of Jinling Pharmaceutical University.

In the laboratory, the researchers bowed their heads and were silent.

On each computer screen, the automatically fitted curves flicker, showing an almost completely parallel trend to the preset curves.

The female researcher at the very door of the research station opened her mouth and swallowed back the yawn that had reached her mouth, and she stayed up for three days and two nights, her eyes bloodshot and scarlet.

The automatically derived curve successfully fell on the preset point, rows of data were automatically generated, and the female researcher reached out to hold the thermos cup containing wolfberry chrysanthemum tea, squeezed it with both hands, and her shoulders trembled uncontrollably.

After staring at the bottom row of 'Ends' at the bottom of the data for three minutes, the female researcher suddenly turned her head, covered her face and cried loudly, shouting: "The medicinal properties test passed!"

The lab became more and more silent, and the researchers who were waiting for the results in front of their computers held their breath for fear of breaking this dream that was so beautiful that it was not real.

Needle drop can be heard in the laboratory.

A male researcher who had to put on a hat because he didn't have time to wash his hair trembled and took out a quick-acting heart-saving pill from his pocket, didn't even drink water, swallowed it directly, rubbed the sticky sweat in his palm on his trouser leg, and trembled uncontrollably when he spoke, "Acting ...... Pass!"

"It's over!" the female researcher who had just joined the laboratory slapped her legs and roared, jumping and jumping with joy, accidentally kicking over the trash can, and a basket full of takeaway wrappers fell out.

But no one will talk about her at this time, seeing that the cold bench that has been sitting for ten years is about to be removed, no one will ever mention their research group with cold eyes and ridicule, and what awaits them is a blockbuster and a supreme glory...... Mo said that the female researcher only kicked over a trash can, and no one would accuse her of being crazy even if she buttoned the trash can.

Some people roared, some screamed, some pounded the table and cried, and some sobbed with their faces.

After a brief period of commotion, the lab fell silent, and all the researchers looked at the booth in the far corner of the lab, where thick books were stacked on either end of the computer screen, and beyond the display screen, all they could see was a head with black and white hair.

At that workstation, sitting is the soul of the entire laboratory - Professor Li Shengnan of the School of Pharmacy of Jinling Pharmaceutical University, the leader of major national science and technology projects, a woman who has been divorced for nearly 40 years and has contributed three-quarters of her life to biopharmaceuticals.

"Professor Li, I'...... We succeeded!"

The male researcher with a hat on his head had a happy look on his face, and he reported to Li Shengnan with his eyebrows fluttering, and at the same time, he quickly tapped his fingers on the keyboard, and the experimental results slipped out of the printer one by one, with the warm scent of ink.

The top of the black and white hair moved, and his voice was as calm as ever, "Well, okay." ”

"Professor Li, we have succeeded! We have really succeeded! The medicinal properties test has passed, our medicine can save people! It can save many, many people!" The female researcher who kicked over the trash can turned red, as if she had opened the tear gate, and her tears could not stop falling. She bit her hooked index finger and told herself with heart-wrenching pain that it wasn't a dream.

Li Shengnan finally raised her head, she brushed back her black and white hair, and finally stood up, with a smile on her face that has hardly appeared in the past ten years, and her demeanor was dignified, "The success of the experiment is inseparable from everyone's help and support, and the production of this clinical drug is my greatest wish and my heart knot." ”

Speaking of the word 'heart knot', Li Shengnan's eyes gradually had tears, her voice was slightly choked, but the smile on her face was as warm as a spring breeze.

"Thank you for giving up your youth and energy to accompany me to create dreams, help me untie the knot, and help all the injured patients who need this medicine to heal realize their health dreams, I thank you. ”

Li Shengnan bowed to everyone.

"Professor Li, you can't help it!"

"Professor Li, we can't afford it! You helped us and taught us a lot. ”

Li Shengnan stopped those who helped her with a smile, and straightened her waist little by little, "I don't have to ask you to stay up late and work overtime with me today, I will give you a holiday until next Monday." Everyone put down all the projects in the lab and took a vacation with ease. Xiao Liu, the final declaration of the experimental project still needs to trouble you to continue to follow up, the most difficult part of the project has been overcome, and the rest are some fragmentary work, everyone must remember to start and finish. ”

"Start and finish!"

The laboratory was full of chanting, and no one could hear that something was wrong with Li Shengnan's words.

The young man who sent away the laboratory, Li Shengnan, who had passed the age of sixtieth year, took out a wallet from his pocket, which contained two ID cards, one was taken by her only a few years ago, showing her decadence and old age, and the other ID card looked a few years old, and the photo was a young man.

The young man on the ID card is her ex-husband, He Chaosheng.

"Chaosheng, did you see it? I finally made a medicine that can save your life, can you see it?"

"Chaosheng, I did everything I promised you, but what did you promise me?"

"He Chaosheng, you answer me!"

"I beg you to answer me!"

In the eyes of outsiders, the 'exterminator Tai', who was as strong as a pine and cypress, was full of tears, staring at the face on the ID card over and over again, asking questions in his heart, but he never waited for an answer.

Everyone who knows Li Shengnan knows about her divorce, but no one knows the reason for her divorce.

Because the family wanted to marry a daughter-in-law for her younger brother Li Guangzong, Li Shengnan had to drop out of school and marry the countryman in her eyes, He Chaosheng. Although He Chaosheng's appearance is upright and handsome, his appearance does not change the fact that he is a mud leg, and Li Shengnan looks down on this man, even if He Chaosheng is a soldier.

In Li Shengnan's opinion at that time, He Chaosheng's military status not only had no value, but also became a shackle that dragged her down. Her military marriage to He Chaosheng bound her for six years, and also made her a widow for six years.

She once resigned herself to thinking that as long as she did well enough, she would be able to keep the clouds open and the moon bright, but she didn't expect that what she was waiting for was a divorce agreement.

Later, she waited for He Chaosheng's martyr's certificate, sacrificed her life for the country, died of serious injuries, and died heroically.

Li Shengnan hated in her heart, she hated that the level of medicine in China was too backward, she hated He Chaosheng's self-righteous machismo, because she said that she couldn't look down on him, He Chaosheng didn't touch her, because she said that let He Chaosheng live and die in front of her eyes, so He Chaosheng really didn't let her see the last side, even if it was a corpse.

How can this man's heart be so ruthless? How can he be so cold and hard?

But she is such a ruthless and hard-hearted person, and all the allowances issued by the army are sent to her without leaving a dime.

The military ID card was snatched away by He Chaosheng's parents, and she rummaged through the bottom of the box to find an expired ID card, and then was kicked out of the house by the He family.

With a sigh of relief in her heart, she took the adult college entrance examination, and after reading it all the way, she was already old in a blink of an eye, and the yin and yang were separated by decades.

"Asahi ......"

Tears fell on the table, overflowed all around, and fell on the old wiring joints.

The sound of sizzling sounded in the laboratory, the electric light flashed twice, and the laboratory was plunged into darkness.
