In the early morning of the next day, Lam was pulled up by the excited Sun who broke into the door early in the morning. After a hurried breakfast, he went straight to Forest Park.

However, Sun insisted on wandering around on the street for a while, then stopped in a neighborhood, and after asking, she found out that she also called Muzi. "Muzi is too housebound, so I have to call her out to meet the sun and take pictures together." Sun explained to Lam.

After Muzi came down, Sun set off directly to Forest Park this time. Along the way, Sun was chattering non-stop, while Muzi had been listening quietly.Lam couldn't help but lament how strange girl's friendship is.

During the period, Muzi looked at Lam and wanted to say a few words, but she hesitated for a while and still didn't speak.

When the three of them arrived, Professor Zhou had already been waiting at the door for a while, and it was not surprising that the elderly got up early. The three of them said to Professor Zhou and entered the park together.

As soon as they entered the gate of the park, Sun excitedly pulled Muzi and went straight to the scenery in front, leaving Lam and Professor Zhou behind.

"Let them play. Lam, walk with me and chat!" Realizing that Professor Zhou must have something to say to himself, Lam slowed down and followed closely beside Professor Zhou.

After walking all the way like this, Professor Zhou kept walking silently without speaking. Lam couldn't help wondering what kind of medicine this old Zhou was selling in his gourd.

At the bottom of the long steps in the middle of the mountain, Professor Zhou motioned Lam to climb up together, and then went to the pavilion above to rest for a while.

In the Hu city, which had just entered summer, although it was morning, the weather had already started to heat up, especially after the sun come out. Fortunately, the bamboos on both sides of the long steps had deep roots and lush leaves, and the green leaves blocked the gentle sunlight in the morning.

If so, Lam was sweating profusely and out of breath when he accompanied Professor Zhou up the long steps to the pavilion on the mountain. On the other hand, Professor Zhou, although he was sweating profusely, was a little more calm.

"Young man, you should exercise more!" Seeing Lam like this, Professor Zhou couldn't help persuading him with a smile, then closed his eyes and took a deep breath, admiring: "The air on the mountain is good, and it's not in vain for us to climb this mountain although it's a long trip."

Lam rested for a while, and finally calmed down. He knew that Professor Zhou must have something to say to him, and asking him to climb the mountain with him should have a deep meaning, but he didn't say anything along the way, just laughed so Lam was a little confused.

Seeing that Professor Zhou was just standing in the pavilion looking at the scenery down the mountain, after all he was young and impatient, Lam finally asking: "Professor Zhou, do you have anything to say to me?"

Professor Zhou looked at Lam. Lam was smart, serious and hardworking. There were not many young people like him. But he also had the problems that young people should have, such as eager for quick success, but these were small problems, because everyone had the young age.

As someone who had experienced this, he hoped that he could give this young man a few words as an elder, as his teacher treated him in the same way back then.

So Professor Zhou nodded, motioned Lam to look at the scenery at the bottom of the mountain, and then slowly said to him: "Lam, in fact, doing scientific research is a very difficult thing, and many times you have to face the future alone. But doing scientific research is like climbing the long steps. If you want to get to the top of the mountain and see the scenery below, you have to climb the long steps."Lam listened quietly, while thinking about the truth in Professor Zhou's words.

Seeing that Lam was silent, Professor Zhou continued: " Do you know what the responsibility of a scientist is and the spirit of a scientist?"

Upon hearing this, Lam's mind suddenly flashed various stories about scientists he read as a child, but he couldn't answer after recalling it for a long time.

Professor Zhou walked slowly to the bench in the pavilion and sat down, then beckoned Lam to come over. He knew that Lam would definitely answer words such as patriotism and hard work, but it was difficult for young people nowadays to feel it personally, so he told Lam a story about an elder.

The names of the elders were not listed for the time being. The elders was born in a scholarly family, and his parents were well-known local intellectuals. It stood to reason that with the family background of the elders, there was no need to work so hard. However, when the elders was young, he realized that there was a huge gap between the physics level of Hua country and Western countries.

So he deliberately found the original English textbook, but he had never learned English since he was a child. In order to understand the content of the textbook, he had to learn from scratch, checking the English dictionary every day, and the progress was very slow. He did not give up and devoted himself to his studies.

Later, the elders received an invitation from a certain engineering university in the United States, and decided to study abroad. Before studying abroad, he promised his teachers in college that he would return after studying and serve the motherland.

While studying in the United States, he was immersed in the laboratory all day long, studying his subject without sleep. Finally, he discovered that the high-energy photon beam of gamma rays was abnormally absorbed when passing through the heavy metal lead.

Unauthorized tale usage: if you spot this story on Amazon, report the violation.

This discovery overturned the consensus of the physics community at that time, and also opened up a new field for nuclear physics research, the elders becoming famous because of it. But the elders didn't take these honors to heart.

At that time, there were constant wars in Hua country, and he just wanted to return to the country as soon as possible, hoping to help his country end all this as soon as possible.

At this time, a scholar in the United States donated 50 grams of radium to him for research, and the elders secretly brought it back to his country for research. In order to prevent the radium from being captured by the enemy , he brought out all the radium.

It was a troubled time, homeless everywhere, and the world was in trouble. The elders insisted on walking.

Later, in order to obtain further information on the production of the atomic bomb, the elders went to the United States to conduct reference research, but the United States placed "espionage" on his head, put him in prison, and tortured him for two months.

In the end, under the pressure of many parties, the US government finally failed to withstand it and could only allow him to return to the country. After returning to his country, the elders immediately devoted himself to research without stopping. In the research and development of the atomic bomb, the elders gave a lot of constructive suggestions to promote the research and development process of his country's atomic bomb.

After Professor Zhou finished speaking, he smiled lightly at Lam: "Lam, you may think that such an old-fashioned story is still being told, but this is the responsibility of scientists. Although each generation has its own mission, as a scientist, the core of which will never change, is to use technology to make the country more prosperous and make everyone's life better. So don't look at the boring and hard work of doing experiments, but the meaning behind it is self-evident. "

Seeing Lam bowing his head in deep thought, Professor Zhou struck while the iron was hot, and told another story, I have a friend... As soon as he said this sentence, Lam looked at him strangely.

Professor Zhou understood for a while, and explained to Lam that he was really a friend, not a friend born out of nothing. Lam was a little embarrassed, and motioned Professor Zhou to continue telling "his" story.

Professor Zhou recalled the past story. When that friend was born, there were many natural disasters in the country. Although he survived by luck, his life was quite miserable. As he grew up, somehow, he fell in love with reading, and every time he went to herd cattle, he would definitely bring a book borrowed from an old teacher in the village.

He read all kinds of books, as long as it was a book, and as long as it was the knowledge in the book, he found it interesting. His family saw that he did not delay the cattle herding, so luckily they let him go.

Only later did he realize how lucky he was to learn so much during those years of mental confusion! Later, the years of ideological confusion ended and the country resumed the college entrance examination. He didn't expect that he could take the exam, so he rushed to take the exam.

How could a person who had not experienced systematic study did well in the exam for the first time, so he failed the exam as expected. He refused to admit defeat, took the exam three times in a row, and failed the exam three times in a row. Fortunately, he was lucky. On the fourth time, he was finally admitted to the university, and entered the school of the elders he just mentioned.

When he first entered university, he didn't understand anything. He didn't understand the profound knowledge of mathematics, physics and chemistry, the responsibility of a scientist, and the spirit of a scientist. They were all taught by the elders.

After graduation, he didn't know what to do. At that time, the work package was assigned, so after saying goodbye to the teachers and classmates, he was taken into the desert and took over a project that he didn't know if he could do it.

When he first took over the subject, he was ambitious, thinking that he must make achievements and leave his name in history, but gradually he found that it was like a bottomless pit. With a full ten years passing, he knew no matter how much time was spent on it, it was nothing with progress. He couldn't help becoming anxious, frowning all day long. He also wrote a letter to ask the teacher for advice, but the teacher's reply was only two words: "Go slowly!"

In this way, he calmed down and slowly advanced the entire research direction, and began to repeat the research day after day.

Later, people began to discuss things like money, and began to say that making missiles was not as good as selling tea eggs.

Later, when his parents were seriously ill, he couldn't afford much money.

Later, relatives and friends laughed at him as a scholar who was useless.

Later, no one knew about the bench for ten years, and once it became famous all over the world.

During this period, he also thought about giving up researching to do business, but the teacher's ardent hope and the charm of scientific laws made him reluctant to part with all these, and he was still selfish after all.

Professor Zhou was relatively relaxed when he first spoke. Later, when he said that his parents were seriously ill, his face was full of tears, and when he talked about others' ridicule, his face was full of sarcasm.

Later, Young Zhou became old Zhou! After Professor Zhou finished speaking, Lam took out a tissue and handed it over.

"Sorry, I lost my temper." Professor Zhou took the tissue and wiped the corners of his eyes, a little embarrassed.

"Professor Zhou, is this friend really your friend?Maybe he is yourself?" Lam asked jokingly.

"How could it not be!" Professor Zhou emphasized quickly, and then took out a book from his bag and gave it to Lam. It was "Showing Sword". The page was deliberately folded by Professor Zhou.

Lam turned to the page folded by Professor Zhou. On it was a passage written by Professor Zhou with a red ballpoint pen, "When ancient swordsmen met their opponents, no matter how powerful the opponent was, even if the opponent was the best swordsman in the world, you have to show your own sword. Even if you fall under the opponent's sword, it is still glorious to lose. This is the spirit of showing sword."

On the side there was a passage of small characters written by Professor Zhou. The handwriting was strong and powerful, "Scientific research also needs the spirit of showing sword".

Lam lowered his head to savor this passage carefully, and changed his previous view of Professor Zhou. He thought he was a shrewd and tactful old man who kept his mouth open and shut all day long in the laboratory, but he did not expect that he was a man with such a story.

Professor Zhou, there was only one character in the single name, Ge, which meant hundreds of boats compete for the flow, and all kinds of frosts compete for freedom.

At this moment, Professor Zhou began to walk down the mountain with hands behind his back, humming a ditty. Seeing Lam's thoughtful and moved expression, he couldn't help feeling proud. Heh, this trick was really tried and tested. The young people were still tender, so they were easy to deal with.

When he thought that his teacher used this trick to deal with him before, he couldn't help but secretly spit out, bad old man, bad guy! But he really miss him, as well as that campus, those classmates who often play together.

Lam watched Professor Zhou humming a ditty as he walked down the mountain, and hurriedly followed, for fear that Professor Zhou might make a mistake going down the mountain.

In the following years, the old people passed away one after another, and their voices gradually blurred. At that time, the human world fell into endless struggle and despair of facing unknown forces. Lam would still think of Professor Zhou's words today. These words rekindled Lam's confidence and courage in despair, and tried his best to leave a glimmer of future for mankind.
