Gao Yuan's words went far beyond a hint. He was practically telling Han Chang outright that Kunlun Company's X3 type fiber likely possessed properties similar to Kevlar!

"Kevlar? How is that possible?!"

"Aren't you researching elastic fibers? How did you take a turn and end up making bulletproof materials?"

Gao Yuan smiled. "Why wouldn't it be possible?"

"X1 Fiber has one model, X2 Fiber has two models. Why can't X3 type fiber have three models, or even more?"

"And do you know what is most interesting about fibers?"

"Fibers with different properties can be combined with one another."

"For example, when X1 type fiber and X3 type fiber are combined, they become highly elastic, quick-drying fabric. With a few adjustments, pushing the moisture-wicking properties to the limit, it becomes swimsuit fabric superior to sharkskin."

"So you see, fibers aren't fixed and unchanging. The more varieties of fibers we master, the more products with different properties we can produce according to demand."

"Recently, I've been considering injecting X3 type fiber into rubber to create highly elastic shoe soles, improving an ordinary person's jumping ability, or taking lightweighting to the extreme and making marathon running shoes..."

Han Chang was stunned. Gao Yuan had shown him the tremendous potential of X Fiber. Jumping shoes? Could ordinary people wear them and dunk?

It sounded incredibly powerful. Once you had black technology, could you really do whatever you wanted?

"I can't guarantee you can do whatever you want, but it should be close enough." Gao Yuan thought for a moment. "From a scientific perspective, love comes from a hormone called phenethylamine. Phenethylamine remains effective toward the same source of stimulation for only eighteen to thirty-six months, which is why people grow tired of the old and seek the new."

"In ancient times, when our ancestors fell for a woman, they would knock her out with a club and drag her back to a cave. That was far too barbaric. As civilized modern people, we could simply inject the woman we liked with phenethylamine, then drag her back to a cave."

"Of course, if you think women are too troublesome, that's fine too. Robotics can fulfill humanity's need for companionship. Pleasure comes from a hormone called dopamine. As long as you get regular dopamine injections, I guarantee you'll feel amazing every day..."

Uh...

Although Han Chang handled logistics, he was still a soldier. Gao Yuan's utterly nonsensical fantasies immediately left him dizzy.

Han Chang pondered it. Tech nerds really were the most terrifying creatures in the world. If Gao Yuan ever became Earth's ruler, the world we lived in would probably feel amazing every day...

"Let's get serious." Han Chang hurriedly stopped Gao Yuan and asked in a low voice, "When will the samples arrive?"

"Tomorrow at noon," Gao Yuan said.

"Excellent!" Han Chang said excitedly. "I'll arrange the testing team right away. The moment the samples arrive tomorrow, we'll put them straight onto the test line."

Suddenly—

Han Chang frowned and said to Gao Yuan, "However, once this thing passes testing, you won't be able to sell it publicly anymore. It will cause you financial losses. You understand that, right?"

Gao Yuan said indifferently, "I know, I know. Military supplies can't just be sold among civilians. Every country places great importance on protective materials. DuPont's Kevlar is embargoed against our country, and its technology is completely blocked off."

"When you think about it, it's pretty frustrating. Materials science is the foundation of all industry. If you can't master materials science, you can't even make a small bulletproof vest, let alone anything else."

"To be honest, since I sent this to you, I was already prepared to lose it. If you think it's good, then keep it."

Gao Yuan spoke casually, but Han Chang, on the other end of the phone, felt something stir in his heart.

Gao Yuan was so young, cheerful by nature, and willing to devote himself to foundational materials research. That was truly rare.

After a brief silence, Han Chang's voice grew much warmer. "You... something this important, and you didn't tell me in advance? How could you send it by courier? You should have informed me so I could send someone to collect it."

Gao Yuan frowned. "There's no need to make such a big fuss, is there? It's not that big a deal, just a dozen or so boxes of bulletproof fiber. I wanted to give you a surprise. Besides, I specifically sent it through SF Express. Their shipping fee is way more expensive than the others."

Han Chang was speechless. It was understandable that Gao Yuan, an ordinary civilian, did not grasp the importance of bulletproof fiber. The fact that he had used SF Express at least showed some awareness of confidentiality.

"Forget it. Give me the tracking number. I'll handle everything from here," Han Chang said gravely.

Gao Yuan truly did not know the tracking number. He usually did not handle such trivial matters and left them all to the chief steward, Cao Feiyu.

So Gao Yuan told Han Chang to wait, then jogged into Cao Feiyu's office. After finding the number, he sent it to Han Chang. Han Chang then reminded Gao Yuan that the remaining materials in the laboratory, along with the chemical formulation, had to be properly safeguarded. Everything would wait until the test results came out.

Gao Yuan agreed readily. When he hung up, he happened to see Cao Feiyu squinting at him.

"Animal, what are you looking at me for?"

"You didn't shave."

"Uh..." Gao Yuan froze and reached up to touch his chin. Sure enough, he felt the short stubble.

"You seem to be in a good mood. What, did you get everything taken care of?" Cao Feiyu asked again.

Gao Yuan nodded, a relieved expression appearing on his face. "It's all done. From X1 to X3, the three major fiber series are our foundation. By combining them, we can create hundreds of varieties. There won't be any problem meeting the needs of the clothing fabric market."

"If we want further development, we'll need to expand in depth and enter specialized fields like bulletproof vests."

"In short, our company's basic framework has already been established. Things should get easier from here on out. We can take a vacation or something. I promised my parents that once I made money, I'd take them to Sanya."

Cao Feiyu nodded slightly and remarked as if casually, "Whatever. Half a year ago, you also promised to treat Jiang Yuanyuan to hotpot."

Pfft—

Gao Yuan's face immediately turned red.

Cao Feiyu shrugged unconcernedly. "Don't look at me. A while ago, I went to the mall to investigate X Fiber's market share and ran into Fan Xiaoyun. Fan Xiaoyun and Jiang Yuanyuan are best friends."

Gao Yuan grumbled unhappily, "It's just one hotpot meal. Jiang Yuanyuan is really petty. Did she have to tell other people about it?"

Cao Feiyu shook his head lightly. "Petty? She was clearly showing off. If you treat someone to hotpot, naturally no one cares. But if the richest man in Shaoxing treats someone, that means something entirely different. Jiang Yuanyuan would feel extremely proud telling her best friend about it."

"After all, you're an important figure now. Whenever your classmates gather, the girls talk about you. Some reporters have even gone looking for our classmates to investigate gossip from your school days."

Gao Yuan was stunned, finding it difficult to accept this change for a moment.

Then he came back to his senses and quietly asked, "By the way, who did you just say was the richest man in Shaoxing?"

"You," Cao Feiyu said, lifting his chin slightly.

Imperial Capital.

Han Chang stood outside the door, straightened his appearance, and took a deep breath before knocking on Ding Songlin's office door.

"Come in!"

"Little Han." Ding Songlin looked up at him, then lowered his head again toward the nautical chart on the coffee table. "Sigh, if only we could reclaim a few more islands in the South China Sea. Those things are like gigantic aircraft carriers that never sink."

"What did you come to see me about?"

Han Chang had long grown accustomed to his superior's obsession with tactics. He said gravely, "Gao Yuan from Kunlun Company just called. He said he has sent us a batch of bulletproof fiber through SF Express and hopes we can test it."

"Bulletproof fiber?" Ding Songlin paused slightly and immediately asked, "What percentage of Kevlar's performance can it reach?"

The moment the words left his mouth, Ding Songlin realized something was wrong. What did he mean, what percentage of Kevlar could it reach? That phrasing was obviously flawed and sounded like he was looking down on them.

But there was no helping it. For all these years, Kevlar had remained under strict technological blockade against China. They could not buy it, nor could they reverse-engineer it. The matter had practically become a heartache for the Equipment Department.

Other than a small number of military enthusiasts, most people did not know this fact: although China exported seventy percent of the world's bulletproof vests, none of those vests used Kevlar material.

Even the bulletproof vests currently used by the PLA were not made from Kevlar.

To put it plainly, the entire Huaxia military did not possess Kevlar bulletproof vests, and Kevlar was the world's most powerful bulletproof material.

The Equipment Department had once obtained a batch of Kevlar from the international market. They could determine that it was an aramid synthetic fiber, and then... there was no then.

They did not know Kevlar's spinning speed during production, its cross-sectional structure, or its pre- and post-treatment methods. They knew even less about the fiber's chemical composition, the blending agents used, or the neutralizers.

People on forums often bragged about how China exported seventy percent of the world's bulletproof vests and could make bulletproof vests as cheap as cabbage.

To be honest, if people from the Equipment Department saw posts like that, they would feel terrible.

Exporting vast quantities of cheap bulletproof vests and capturing the global market was, of course, a good thing. It demonstrated formidable industrial capability.

But the key was that they did not want their own soldiers wearing the same cheap bulletproof vests. They wanted something expensive but powerful as well, yet they had never had it.

Faced with Ding Songlin's question, Han Chang thought for a moment, then frowned and said, "Based on my understanding of Gao Yuan and his dedication to technology, since he dared send it directly to us for testing, its performance is probably no lower than Kevlar's. It may even surpass Kevlar."

"What?! Better than Kevlar?!"

With a swish, Ding Songlin sprang to his feet and slammed the table, his eyes turning red.

Starting today, Huawei had officially been cut off from supplies. It seemed that the story I wrote in my previous book was gradually becoming reality.
