As soon as the underground water channel was excavated and the seawater separation and purification plant was built, these things were already familiar, and Lin Feng asked Han Minghao to send someone over at will.

Lin Feng is twenty days in South Africa in the blink of an eye, and it is about to enter the middle of March, and things here are almost on the right track, as long as the first batch of oilseed and wheat rape is ripe, and then the distribution of starry sky silkworms will be completed, presumably by then the underground waterways and canals have all been completed.

Back in Linjia Village, he couldn't wait to come to the laboratory and check on Sima Lili's work first. It's not that she has achieved anything, but that she doesn't overwork.

"You're coming back pretty quickly," Sima Lili's figure was a little fatter, and she looked more charming, the most important thing was that her mother raised an old hen every day, "but it just so happens that our car is being assembled and tested, and you can be a tester." ”

The two went to the laboratory where the car was assembled, only to see an avant-garde car, waiting to install windows and glass, and some young geniuses in the laboratory were testing its intelligent system.

"Is there any problem?" Lin Feng asked.

"The biggest problem is the positioning system," said Sima Lili, "You know that GPS has now limited some of our functions, and the Beidou system is not yet perfect for civilian use, so it is difficult to achieve very accurate positioning control." ”

Lin Feng said half-jokingly: "Do we still have to launch a few satellites by ourselves?"

"If you can, that's for the best. ”

"You're serious, I'm just kidding. ”

Although he can buy ready-made satellites, just like the Heavenly Punishment System, which can be monitored from any corner of the world without dead ends, but now that they have their own research and development capabilities, he doesn't want to rely too much on extraterrestrial technology.

Just developing a global positioning system is not an overnight thing, and he doesn't want to wait another year and a half.

"Lin Feng, you know that when I do one thing, I must do my best whenever possible. Sima Lili pulled him to the empty laboratory next door and said affectionately, "So if we can really launch satellites ourselves and build a more advanced positioning system, even if we launch a new car a year and a half later, what does it matter?"

Lin Feng knew that she was serious, this girl was good at everything, but she always tried to be perfect in this part of technology. If the new car is equipped with a GPS system, many functions cannot be played at all, which is something she resolutely cannot bear.

"But my dear, we don't have a lot of time," Lin Feng said, hugging her waist, "We're not young anymore. ”

If you want to go to the vast universe, you need to do it as soon as possible.

Of course, this sentence can't be said, if Sima Lili knew that one day they could go to the universe to wander, it is estimated that she would be eager to leave immediately.

"You've got to help me figure it out. Sima Lili pressed him tightly against the wall, refusing to let go, "If you don't think about it, I will be anxious, anxious, and unable to eat, and your son will be stunted......"

"Stop, I'm scared of you, can't I surrender?"

Lin Feng felt that there was no one left, this girl had learned to coerce the Son of Heaven to order the princes!

"Just know you have a way. ”

Sima Lili happily got into his arms, and a tempting fragrance wafted from his body, and after more than 20 days of not seeing him, the two of them were like dried vegetables on fire, and they ignited with a snort.

"Lin Feng, you light, the doctor said it is best to control ......"

"I will start controlling it tomorrow, and I can't control it today......"

After more than half an hour of "discussion", Lin Feng decided to rent a positioning system.

Now he uses the multi-functional bracelet, the automatic driving system on the car, the heavenly punishment system, the Shenxiang, etc., are connected to an unknown set of global positioning, real-time monitoring system, this system is really powerful, as long as it is on the surface, or dozens of meters underwater, it can be monitored clearly.

So he can be sure that there must be such a system working around the earth right now.

If they can connect their cars to this system, then the new cars will be able to do all the functions. In Sima Lili's words, it is not a few generations beyond the current car, but directly beyond the 30 generations, and even more advanced and excellent than the one Lin Feng bought from the Universe Mall in some aspects.

He went to the mall to post the task, and sure enough, someone picked it up quickly, and there was a reply within a few minutes. If you want to access this planetary surface positioning system by yourself, you need to pay 2 billion RMB a year, and the access limit is 2 billion terminals.

This system is called "Tianji", and it is rented mainly for the service of new cars, so this cost should be calculated on the head of the car company in the future. But Lin Feng felt that of course this money could not be paid by him alone, and the country would definitely be able to use this system, right, so he was ready to find a time to talk to Political Commissar Li about the advantages of this system.

After paying the service fee for 10 years in one go, Lin Feng received a management terminal, which was actually a metal ball that could unfold a light curtain. Through this light curtain, you can see the number of real-time access to the Tianji system, users, and you can also set permissions through the terminal, such as restricting the use of regions, limiting access types or access numbers.

In fact, this terminal is dispensable for Lin Feng, but it is more important for the country, and if it is accessed by foreign forces, it will cause immeasurable losses.

Therefore, Lin Feng and Sima Lili studied for a whole day, and finally divided the access user authority into ABC3 levels.

Class C only has the ordinary precise positioning function, Level B adds real-time monitoring function on the basis of Level A, and Level A is like a natural punishment system, which not only has no restrictions, but also has the highest priority.

At present, only Lin Feng has A-level permissions, and it is only temporarily open to the state to B-level, and only to the general public to C-level, and it must be limited to use in Huaxia.

As a result, the intelligent system of the new car will have to be reprogrammed, and Lin Feng feels that it is a kind of ordeal to let these guys who study physics write the program.

Although everyone has rigorous thinking and an attitude of striving for perfection, sometimes ten people have ten different opinions for a line of code, and finally have to make trouble with Sima Lili to arbitrate, which really makes him a little unbearable.

So he told them to go back to studying molecules, and he went to the Universe Mall to find professionals to do this kind of thing.

Less than three hours after the mission was released, a set of system programs for autopilot, safety protection and intelligent chat was sent to his mobile phone.
