When Yan Yun was tired to the point that his eyes were straight, his mouth was dry and his entire body was itchy … Oh! It should be because he was exhausted, that he finally explained it to Lu Zhengwen so that he wouldn't have to use the title of "Model Change Hero" or something like that.

However, Yan Yun realized that he had underestimated Lu Zhengwen. When he left the police station, Lin Xiao walked out with a face full of schadenfreude, and handed him a red book.

"Yes!" "Our good citizens, your gift earlier was not bad. Thank you very much, sir."

Yan Yun held onto the "Five Great Citizens" red book, and looked at Lin Xiao's swaying back as he walked into the police station. In that instant, he almost wanted to cry. If Mo Le and the others saw this, they would definitely use this matter to tease him!

He fiercely stabbed his middle finger at Lin Xiao's back, causing Yan Yun to leave in a depressed mood.

Sitting in the taxi, Yan Yun was deep in thought. Lu Zhengwen and the others only thought that it was an ordinary bandit case, but they did not know that there was an earth-shattering secret hidden inside. Maybe they would have some suspicions during the investigation, but Yan Yun was sure that they would not find out about it.

Level 10 secret! This was a very heavy word, so heavy that even Yan Yun couldn't help but ponder over it. He looked through the document and knew the contents.

Although this was just a piece of paper, it was related to the future development of the countries on Earth. Who could become the overlord, who was about to be eliminated, everything was in this paper.

HST! A new type of alloy, "Black Emperor".

Yan Yun was also somewhat knowledgeable about science, but the three characteristics of the "Black Emperor" alloy were clearly described in the document: Hard, Light, and Filtered Sonar.

It was because of these three special characteristics that made Yan Yun quiver all over. The "Black Emperor" alloy was a hundred times tougher than diamond and it could be mass-produced.

For example, if the "Black Emperor" alloy was used to make an airplane, its toughness would be enough to withstand the normal missile attacks. Other than nuclear missiles, there were almost no heavy weapons that could destroy the plane in one hit.

Furthermore, because the "Black Emperor" was extremely light, the plane's body was extremely flexible, and had the super characteristic of being able to defend against sound waves. This aircraft was basically invisible.

Such a killing machine, not only was it incomparably flexible, but it also came and went like a shadow. If it were to join in the war … Yan Yun sucked in a cold breath of air.

Moreover, these three characteristics were only discovered so far. Other than that, he did not know if there were any other attributes, but the paper also mentioned a prediction, that the 'Black Emperor' alloy had a huge relationship with the magnetic field. If he could develop it further, perhaps he could use the magnetic levitation technique to its limits.

Imagine, if everyone could have a car made of "Black Emperor" alloy and fly in the air with its maximum magnetic levitation power, wouldn't humanity have entered a new era?

Humans had experienced three technological revolutions, and the feudal era in China had left them far behind other countries. Even though the country had been developing with all its might for decades, catching up to the third technological revolution was only catching up to the later stages, and the results were not too remarkable.

Was Yan Yun patriotic? The answer was yes, Yan Yun was very patriotic, there was no doubt about that. People like him lived in foreign lands all year round, so his attachment and attachment to his homeland was greater than anyone else's.

Therefore, the "Black Emperor" alloy Yan Yun would hand him over to the nation. With his eyesight, he had long judged that the fourth scientific revolution was about to begin, and the "Black Emperor" alloy was the most important link.

What is the most important thing for a developing country?

He took the initiative!

Nothing was more important than taking the initiative first. Wasn't it because the powerful countries of A took the initiative to develop and become stronger that they took the initiative? If Huaxia had the upper hand in the fourth revolution, the world would have changed dramatically.

This was a nightmare for Country A, but for the Chinese citizens, this was undoubtedly a heavenly blessing. Who wouldn't want to take revenge for those eight years? Who doesn't want to be envied in a foreign land?

Look, are those Chinese? Wow, the world's top power.

I must find a Chinese husband in the future. This is my lifelong dream.

Just what kind of honor was this, for the Chinese to become expert's symbol, a person as strong as the A-Nation's blonde beauty, to dream of marrying a Chinese.

While he was deep in thought, Yan Yun's mobile phone rang.

Looking at the phone number and pressing the answer button, Yan Yun went straight to the point: "Did you manage to find anything?"

"Boss, I found it. The address of the research institute for chemical biology is..." Zhang Faner's voice sounded.

"If you go with Mei Ying, you must control the situation. I want all the information there." Yan Yun's cautious and serious voice sounded.

"Alright!" Zhang Faner hung up the phone very quickly. Since the boss wanted him to go with Mei Ying, the importance of the matter was self-evident. He had to make full use of this chance.

The moment Yan Yun saw the "Level 10 Secret", he had immediately followed the clues written on it and notified Zhang Faner, telling him to investigate the research facility that had come up with the "Black Emperor" alloy.

The reason why the poisonous python obtained such an important secret was because it originated from Jinghai. The meaning behind this was obvious.

Who leaked the secret? Sold to the Poison Python without permission?

Without a doubt, Du Mang would definitely not give the "Black Emperor" alloy to Hua Xia. Otherwise, after the accident, he would not immediately order his men to leave.

Such an important secret about him being ill had obviously made Du Mang uneasy. He only wanted to get to his base as soon as possible and take care of everything in peace.

It was such a coincidence that Yan Yun actually encountered it. He smiled happily, could it be that this was heaven's will?

Tianxing Huaxia!

"Master, let's not go to the Peking University, let's go to the North Star Region!" Yan Yun said a few words to the taxi driver, then he closed his door and meditated, his mind was thinking about the crux of the matter, trying his best to not leave anything out.

How many people know about the "Black Emperor" alloy? The reason for the research was that the director of the research institute might know about him, as well as the group of Poison Mang.

These people were all killed by Yan Yun, but was there anyone behind Du Mang? Did they know? This is worth considering.

Also, what form would Yan Yun use to hand over this honor to a country? Giving such an important item to an average person was not safe at all.

For a country, this was an opportunity to rise up. However, for an individual, this was an enormous temptation. The person who sold the 'Black Emperor' without permission would not be able to endure this temptation. Perplexed, he wanted to trade the "Black Emperor" for the wealth of his lower body.

There were a total of fifteen floors in the Flying Cloud Mansion, so it wasn't particularly outstanding when mixed with the surrounding buildings. It wasn't as famous as the Bright Moon Mansion, but was actually the location of the "Research Institute for Metamorphosis".

The seventh, eighth and ninth floors of the building were all rented out by the "Research Institute for Metamorphosis".

When Yan Yun arrived at this place, he discovered a layer of charred traces on the exterior of the building's 789th floor. This made him slightly astonished.

Chu Yunxi, why is she here? Did she know about this as well?

Yan Yun was startled, then he walked towards Chu Yunxi.
