A few days passed in the blink of an eye.
Lin Chen and his wife's honeymoon was coming to an end.
"Host, your stealth unmanned mini-attack submarine technology has reached the Grandmaster level."
The system's voice sounded in Lin Chen's mind.
This Grandmaster level required thirty hours. If he hadn't come to the seaside for vacation and conveniently played with this, it might have taken him half a year to reach the Grandmaster level.
Massive amounts of information quickly flooded into Lin Chen's mind.
Before long, a look of pleasant surprise appeared in Lin Chen's eyes.
This technology included missile technology, but it was only at the Grandmaster level. Missile technology was not very useful to Lin Chen, as China's missile technology was already very strong.
The Grandmaster-level stealth technology was also just average.
Lin Chen believed that China's current technology in this area would not be much worse.
But the skill he obtained was comprehensive.
There were two aspects that were likely to be more advanced than China's current technology.
One of them was solid-state battery technology.
According to the information he obtained, the solid-state batteries used in small stealth unmanned attack submarines, knowing the raw materials and principles, manufacturing them was not too difficult.
However, possibly because it was only Grandmaster-level technology, the solid-state batteries he knew about required the use of special materials, making them very expensive to manufacture.
It was not suitable for use in ordinary products.
But this was not a problem for submarines. Submarines did not need to be built in large numbers; performance and reliability were more important.
Another potentially leading technology was deep-sea power generation technology. According to the information he obtained, the special material used for the submarine's outer shell could generate a special force field to drive a force field generator under strong water pressure.
The electricity generated could be stored in solid-state batteries.
However, the Grandmaster-level was a bit low, and there were some minor problems with manufacturing this type of small conventional unmanned submarine.
That was the cost.
In a word, expensive.
If it were manufactured, the range would be excellent. As long as it was not driven intensely, it would have almost unlimited range, but its manufacturing price could be as high as hundreds of millions of US dollars.
This price was more expensive than manufacturing a conventional attack submarine.
Of course, this type of submarine was not without its advantages. The biggest advantage was that there were no people on board. If it was sunk, there would be no casualties, allowing it to carry out dangerous missions.
Without people, there was no need for living space inside. Although this submarine was much smaller, it would not lack missiles, torpedoes, or anything else.
Its combat power was still formidable.
"Daddy, what are you thinking about?"
Lin Xiaoxi asked in a childish voice.
Lin Chen came back to his senses and said, "Daddy is thinking, we'll be going back in a few days. If we want to play with this model again, where should we go to play?"
Lin Xiaoxi: "Daddy, we can play something else."
The environment has a significant impact on people.
At the beach, Lin Xiaoxi was interested in playing with models, but when she went back, Lin Xiaoxi's interest in this would definitely decrease.
"Daddy, let's go play something else."
"Let's go catch fish."
Lin Xiaoxi giggled.
"Okay."
Lin Chen smiled slightly.
Catching fish was also a type of hunting, which could improve tracking skills. His tracking skill was currently at the Grandmaster level, but it was not far from the Great Grandmaster level.
Lin Chen estimated that he could break through before going back.
...
"President Xu."
Liu Feng approached Xu Mengyao on the beach.
Lin Chen and Lin Xiaoxi were diving and catching fish.
Lin Chen did not use diving equipment, which could improve both his Turtle Breathing Technique and his Tracking skill.
"What's the matter?"
Xu Mengyao asked.
Although Liu Feng and the others were protecting them on the island, Liu Feng and the others had not approached to disturb Lin Chen and his family for so long.
Liu Feng hesitated a bit.
Xu Mengyao had a bad feeling in her heart. She asked, "Liu Feng, if there's anything, please tell me."
Liu Feng: "Ms. Xu, let's talk about it together later."
"Call Mr. Lin and the others up first."
Xu Mengyao picked up a remote control. She pressed the remote control, and something on Lin Chen's body vibrated.
Soon Lin Chen surfaced with Lin Xiaoxi.
"Liu Feng, what's wrong?"
Lin Chen asked after going ashore.
Liu Feng looked at Lin Xiaoxi.
Lin Chen squatted down and said to Lin Xiaoxi, "Xiaoxi, go play in the sand for a while. Uncle has something to say to Daddy and Mommy."
"Okay."
Lin Xiaoxi ran to the nearby shade of a tree.
Liu Feng said with a solemn expression, "Mr. Lin, Mr. Xu Guofeng has encountered a little situation. He went to Africa on a business trip, and that country has broken out in civil war."
"Mr. Xu Guofeng's area has been occupied by rebels."
Xu Mengyao's face changed drastically.
Lin Chen held Xu Mengyao's hand. He said in a deep voice, "Why didn't my dad call us?"
Liu Feng: "The communication there is cut off. We also learned about this news through special channels."
Xu Mengyao said in a trembling voice, "Husband, what should we do?"
"Don't panic... Liu Feng, has my dad been captured yet?"
Liu Feng: "We used satellites, and from the pictures taken by the satellites, he should be safe for the time being, but they may be found by nearby rebels at any time."
"I'm not very clear about more details."
Lin Chen nodded slightly: "Okay, I got it."
Liu Feng saluted and walked away.
Xu Mengyao said bitterly, "Husband, I should have persuaded Dad more. It would have been better if he hadn't gone abroad."
Lin Chen also knew about Xu Guofeng going abroad.
The Xu family had a lot of business abroad, and some things couldn't be handled by sending other people from the company.
"Wife, I'm afraid there's something strange behind this."
Lin Chen said.
Xu Mengyao asked in confusion, "Husband, what do you mean—"
Lin Chen: "When Dad went abroad this time, the National Security Agency must have assessed it. The political situation in the target country should be stable, at least there definitely wouldn't be any problems in the short term."
"But it just so happened that a civil war broke out."
Xu Mengyao's face changed slightly: "Husband, do you mean, this might be aimed at my dad?"
Lin Chen frowned.
"No, this might be aimed at me."
"Even without this 'accident', there would be other accidents. I feel like someone is forcing me to go abroad."
Xu Mengyao was uneasy.
"It would have been better if Dad hadn't gone abroad this time."
"I should have persuaded Dad more."
Xu Mengyao blamed herself.
Lin Chen reached out and wiped away Xu Mengyao's tears: "This is not your fault. I also knew that Dad was going abroad. We can't always be cowards just because there is danger."
"Besides, even if we have always been in China, as long as some people want to, there are still other ways to force me to go abroad."
"Don't worry, Dad will be fine."
Xu Mengyao hugged Lin Chen.
"Husband, I'm worried about you."
"If they are coming for you, Dad will definitely be fine now; if they are not coming for you, the rebels should not mess around after the country's negotiations."
"But if you go over—"
Xu Mengyao said worriedly.
A sharp glint flashed in Lin Chen's eyes: "If I go over, they will be miserable."
"It's best if this matter is just a coincidence."
"If not, many people will be out of luck."
Lin Chen exuded a powerful aura.
He was a Martial Arts Grandmaster.
Moreover, the system space now has three thousand cubic meters.
"Wife, let's go pack our things, our vacation is ending early."
Lin Chen kissed Xu Mengyao's forehead.
