Not long after returning to the yurt, the old patriarch came and so did Humir.

Humir wiped away his tears and applied medicinal wine to Lin Shuhang, but before leaving, he burst into tears and smiled. He suddenly hugged Lin Shuhang's naked upper body and said shyly: "Don't fight so hard in the future... you are my man."

, you don’t have to prove anything to anyone! No one can take me away from you!"

this……

Although Humir's freckles are not his type, the gentle whispers in the dim tent and the girl's breath in his ears are really a bit...

But at the same time, Lin Shuhang suddenly thought of a very serious question.

The day after tomorrow is his wedding to Humir. The old patriarch had already mentioned this when he came to see him, saying that the tribe had already begun to organize.

And if the expected danger has not arrived by then, then there will be two things that will make Lin Shuhang very embarrassed.

First, don’t you need a bridal chamber to get married? Then do you have a bridal chamber or not?

Secondly, although after the simulator was upgraded to version 1.0, there was a discrepancy between the real time and the time in the cause and effect scenario, but it was only 10 times the time difference. Staying here for three days is equivalent to spending time in reality.

More than six hours, so it should be two o'clock in the morning.

Tomorrow I have to go to the school to sign a contract and make a formal report. Before I find a way to use the simulator to make money, I must not lose my job. Otherwise, wouldn't I have changed from a small student to a big worm?

That would go against his original intention.

He will definitely go to the school report tomorrow morning. He can't really get married and have children slowly in this simulator. If he registers at school at 10 a.m., he can only stay here for six or seven days at most.

Will he commit suicide then?

...it's nerve-wracking, no matter what the crisis is that is still brewing, I hope it comes soon.

After the old and the young left, Lin Shuhang endured the soreness that felt like his whole body was falling apart, walked on the Mizong Steps a few more times, and practiced Fuxi's Little Zhou Tianxin Technique several times.

I'm not a masochist, the main reason is that this can quickly restore spiritual energy, thereby accelerating the recovery of the physical body.

Recovery is always much faster than development. After several trips, Lingyuan has reached full capacity again.

It can be clearly felt that the restored spirit essence is much thicker than before. If the spirit essence before was as thin as a fishing line, now it is a bit like wool.

Well, I have worked hard to practice knitting...

I lay down exhausted, and when I got up the next day, my body had completely recovered from the fatigue. In addition, Humir's medicinal wine had been so powerful last night that no bruises were left, but my eyes were still slightly swollen.

, but you have to look closely to notice it.

It’s another day full of energy!

Due to his injury yesterday, Humi Langtai thought it would take several days for him to recover, so he canceled today's morning class early.

If you don’t have to go to the school to teach the children, what are you doing? Of course, go to the grassland to find the lovely Kuotaizhe Farewell.

Unfortunately, he didn't see him after walking around for a while. Finally, he finally heard someone say that he was drinking in Uncle Getai's tavern, and Lin Shuhang went directly to find him.

As a result, the most powerful warrior of the Tufang tribe did not get drunk after drinking three cans of wine. However, when he saw Lin Shuhang, he was stunned and passed out on the table without saying a word. He could not wake up even if he shouted.

I'm really drunk and pretending to be drunk... I feel like I'm not willing to teach myself anymore.

Lin Shuhang felt very sorry for this. Kuotai was actually quite a nice person, straightforward and honest.

Forget it, just practice it yourself.

He went to the grassland to practice wrestling for a while, and also found some students who had attended class yesterday to practice sparring, but these students were completely unable to compare with Kuotai in terms of strength and skills.

In addition, I witnessed Lin Muyuan's desperate attempt yesterday, so I was scared when I was sparring with him. In this narrow encounter, the brave will win. How can a wrestler still fall if he is scared?

After practicing for a while, the simulator showed no reaction at all. It was obvious that he had not improved himself, and Lin Shuhang suddenly lost interest.

It seems that it needs a broad platform... To practice martial arts, you have to find masters to torture yourself, so that you can improve quickly.

After instructing the children to practice on their own, Lin Shuhang returned to the yurt.

Kuotai will definitely ignore him today. Although he can't practice martial arts, it doesn't mean that he has nothing to do.

He has to calculate the latitude and longitude of this place!

If you want to bring the two parchment scrolls as family heirlooms to yourself two thousand years later, you can only bury them in a secret place. If you want to find the buried things two thousand years later, at the very least, you must know your accurate longitude and latitude coordinates.

.

As early as when he had just made this plan, that is, when he returned to the airport in City C, Lin Shuhang had already checked the information on the Internet and learned how to calculate the longitude and latitude using the most limited conditions.

Frankly speaking, if you don’t check, you won’t know. If you check, you will be shocked. It is really difficult and difficult...

Latitude is relatively easy to measure. It mainly relies on observing the altitude and moving direction of Polaris. This method is very easy to use in the northern hemisphere, and the Mobei he is currently in happens to be in the northern hemisphere.

However, you have to wait until night to see the stars. It is broad daylight now, which is the time to calculate the longitude, and this is really the most difficult part.

In the absence of mobile phones or satellite positioning, there are generally two methods to measure the longitude of the earth.

One is the moon phase method, which is calculated by observing the shadow changes on the surface of the moon. However, let alone the complexity and difficulty of the calculation, the key point is that it is useless without an astronomical telescope. You can see it with the naked eye.

Craters on the moon? Not to mention precise shadow areas.

The second one is slightly more reliable. It is measured by time. It mainly relies on measuring the height of the sun in a day and comparing it with the time difference on the clock to determine the difference in longitude. The earth is divided into 360 degrees and there are 24 hours in a day, so one degree is 15 minutes.

, so as long as the time is accurate enough, down to milliseconds, the accurate longitude can be calculated.

But this is the same as the moon phase method that requires a telescope. If this method was really left in ancient times, there would be no way to solve it.

After all, the first accurate clock invented by humans on earth was already in the 17th century. But Lin Shuhang is different. There is a system mall. Although only the primary area is open, ordinary supplies such as astronomical telescopes and clocks are actually available.

, and quite high-end.

The clock is much cheaper, only 10 Karma Coins, and the algorithm is relatively simple compared to the moon phase method, so I naturally chose this one.

Of course, the so-called "relatively simple", whether it is using time to measure longitude or using Polaris to locate dimensions, is only for professionals.

But for people like Lin Shuhang who are now learning and selling their knowledge, and even need to look up the North Star on the Internet, it is really difficult to reach the sky.

Fortunately, after passing the prologue, the growth of mental power has also improved the intelligence to a certain extent. Things that seemed very complicated in the past can now be understood after studying online.

No matter how difficult it is, as long as there is a method, it will eventually be solved. The rest is just continuous experimentation and accumulation of experience through practical operations.

Lin Shuhang is really serious about this. After all, if he can really give something to himself after 2000, then this skill will be something he will need to use frequently in the future. No matter how difficult it is, he must thoroughly study it.

But this time he didn't buy a clock. After all, when he first entered the scene in this chapter, he didn't know what he would encounter. If he died after entering, it would be a waste of Karma coins.

But this does not prevent Lin Shuhang from taking the lead in learning and practicing. Of course, it is impossible to observe the height of the sun directly with the eyes, which is both dazzling and completely inaccurate.

He asked Humir for a long bare pole, and Lin Shuhang inserted it in the open space in front of his house. Humir thought he wanted to set up a flag. After all, he was about to get married, and having a family represented independence.

According to tribal rules, flags can be erected.

So he was quite enthusiastic and active in making suggestions. He was wondering whether to draw the clan logo or a totem such as a wolf on the flag, but he heard Lin Shuhang say: "No flag, this is a scientific observation. When the sun shines on the bamboo pole, it leaves

shadow to calculate the exact time of day and the height of the sun from us..."

Lin Shuhang talked a lot. In fact, it was not for Humir to listen, but a process of continuous thinking and self-enlightenment while concentrating. Some of the words even had no preface and follow-up, and the wording was inaccurate.

, after all, he is just a beginner.

But Humir was stunned for a moment.

Sun? Height? Scientific observation?

Isn't this... the sun transformed into a big bird? This can also be observed? What is the purpose of observation?

As she thought about it, the little girl's face turned red again. The few freckles became clear under the sunlight, and her eyes looking at Lin Muyuan were even more radiant.
