Because he was preparing to participate in the military expedition, Zhou Changfeng did not stay in Jiujiang for long, and he set off for Beijing on 24 February.

Before leaving, Zhu Lingjing sent him a very delicate letter, thinking that there were still some secret things to be told in writing, but the result was ......

"Mysterious," Zhou Changfeng muttered as he opened the envelope in a cubicle in the toilet of the train station, "Didn't you say that there was nothing about me recently?" It's ......."

The muttering came to an abrupt end, because there wasn't any letter at all, but two checks.

One is 90,000 yen, and the other is 9,000 yuan.

Grass!

If it were Arabic numerals, Zhou Changfeng would probably feel that he was dazzled, but the Chinese characters on this check were capitalized, "Jiu Wan Yuan" and "Jiu Qian Yuan", which were clear.

He immediately recalled what Zhu Lingjing said on the phone some time ago, "I prepared a gift money for you".

It's true that it does what it says, but this huge amount of money is really terrifying, roughly converted according to purchasing power, it is equivalent to 9 million yuan.

In contrast, he made such a feat on the front line, and the reward he received in exchange was only 10,000 yuan.

No wonder some people are willing to go to the rich woman, just this treatment, I'm afraid that they are not willing to get rich.

Sighing at Zhu Lingjing's generosity, Zhou Changfeng carefully put away the two checks, and then left the toilet casually, went to the platform and boarded the train to the capital.

He was still a little entangled when he passed through Wuhan, because his sister invited him to go back to his hometown several times in the letter, but he kept shirking it, and now he can't stop through Wuhan, and he should be able to pass through the door without entering.

Because he was traveling on business, Zhou Changfeng took a first-class car, which was divided into multiple compartments and spacious bunk beds, so the fourteen-hour trip was not sad.

When the train stopped at the Hanyang train station, a raunchy young man with a handbag came to his cubicle—his hair was messy, just tied casually, and the whole person was in a trance, as if he was thinking about something.

The tickets for the first-class train are relatively expensive, they are not full, and there are only two of them in the four-person compartment.

It wasn't until the evening that the two finally got into a conversation.

Zhou Changfeng learned that his name was Zhang Shilin, and that he was a bachelor's (doctorate) student in the Department of Chemistry of Imperial Gezhi University, and because the research he was engaged in was more troublesome, he had to travel back and forth between Beijing and Wuhan frequently.

“…… So, what do you do? ”

"Nuclear transmutation is the transformation of one substance into another."

Hearing this, Zhou Changfeng, who was eating dinner, almost choked on a mouthful of rice, and hurriedly took a sip of soup.

Although transmutation is not as well-known as fission and fusion, he has heard of it a little—it refers to the transformation of one element into another, or the transformation between isotopes; Transmutation can occur naturally or artificially.

Just a few years ago, the Hungarian physicist Szilard proposed the conjecture about the chain reaction; Marie Curie's daughter, Irena and her husband, Jori, also publicly announced that radioactivity could be artificially induced, causing a great stir, as it had previously been widely believed in the scientific community to be naturally occurring.

As a result, this aroused the interest of many scientists around the world and began to devote themselves to this research.

"The road to the origin of things is full of unknowns and surprises," Zhang Shilin raised his fist and longed: "One day we will be able to turn lead into gold!" ”

In the eyes of the circumference, his image is somewhat of Frankenstein, with the only inconsistency being that his spectacle lenses are thinner than the bottom of the bottle.

After thinking for a few seconds, Zhou Changfeng asked, "What are you bombarding the nucleus with now?" A rays? ”

Aha? There are still officers who understand this?

Zhang Shilin, who was amazed, was stunned for a moment, and then replied: "The efficiency of the reaction caused by the bombardment of nitrogen, boron, and aluminum by the A ray is not high, and we have now switched to neutrons, and the results are remarkable. ”

The so-called A rays are α rays, and the three types of rays A, B and C represent α, β, and γ rays respectively.

α rays are essentially high-velocity helium nuclei, made of two neutrons and two protons, which carry two units of positive charge and have a large mass.

Because it is charged, it will be repelled by static electricity when it hits the target nucleus, so it is not easy to hit and is not efficient.

The discovery of the neutron, an uncharged neutral particle, that was discovered only a few years ago, seems to have opened a wider door?

Charged particles consume energy as they penetrate matter, however, electrically neutral neutrons are very different – they are only affected by strong interaction forces when in close contact with the nucleus.

Zhou Changfeng pretended to be casual and said, "In this way, have you tried to bombard some special heavy elements?" Like what... Uranium? ”

"No," Zhang Shilin shook his head, feeling a little inexplicable, "What are you using it for?" What is it to turn it in? ”

By bombarding the nucleus to change the number of protons, as long as element 79 can be obtained in the end, then artificial gold is truly realized, and that is the technology that changes the world!

However, it is reasonable to assume that it is best to use elements with atomic numbers similar to those of element 79, such as element platinum 78, mercury 80, and lead 82.

Zhou Changfeng couldn't help but regret this, he couldn't control the research topics of the Imperial Gezhi University now, and it was impossible for the ongoing scientific research projects to stop.

But the good news is that, according to Zhang Shilin, there is similar research at Suncheon University of Technology, but it is not going well.

In the early morning of the next day, before dawn, the moon was dark and the stars were shining, and the last quarter moon in the sky had come to the west and was about to set.

Just after the hour, Zhou Changfeng took a ferry to Jiangnan, and found that it was still early, so he took a ride to the vicinity of Dingjia Lane on Chaotiangong West Street.

He raised his hand and looked at his watch, it was more than six o'clock, and there was a ninety percent chance that Xia Xiaoshi hadn't gone out yet.

As it turned out, only half an hour later, Zhou Changfeng, who was pacing in place, caught a glimpse of a figure pushing the door open.

"Huh?" After a brief moment of surprise, she stepped forward and said happily, "You're back so soon?" I thought I would have to wait for half a month. ”

"Because everything went well."

"Oh, I see... Run, the car is coming! ”

The two of them ran briskly for a while, and as soon as they reached the station, they saw the tram slowly approaching.

Fares are divided into three classes, starting at two cents and increasing up to four cents depending on the distance.

I haven't seen him for many days, Xia Xiaoshi has more words than Zhou Changfeng, and it doesn't matter if she asks this and that.

Seeing that she was so happy, the latter was a little embarrassed to tell her the "bad news", and after a few seconds of entanglement, he said: "I have something to tell you, well... I may have to go to Spain with a military expedition in a few days. ”
