"Synchronous geostationary orbit?" Ye Fei heard a familiar term and couldn't help laughing, "No wonder, it seems that there are still some systems in the wreckage of the spaceship in the sky four hundred years ago that can be used normally...... Damn, why do I think this place is getting more and more mysterious? ”

The so-called synchronous geostationary orbit refers to a circular orbit located at a certain height above the equatorial plane of the planet, where the rotation time of the artificial celestial body coincides with the rotation period of the planet.

From the ground, satellites or other aircraft at this position are always stationary, and satellites located in this position are also synchronous satellites in the general sense.

In reality, however, geosynchronous orbit and geostationary orbit are two different concepts.

The similarity is that the satellites orbit the planet in the same amount of time as the planet rotates.

The difference is that the stationary orbit is located directly above the equator, embedded in the plane of the equator, and its relative position remains the same, and it is always there whenever it looks up.

The position of the geostationary orbit satellite is not within the equatorial plane, and its orbital plane has a certain angle with the equatorial plane, so it is not fixed at a certain point from the ground, but above the same point at the same time every day.

To paraphrase the vernacular, the satellites on the equator are geostationary orbits, and those that are not over the equator are called geostationary orbit satellites, although the latter orbits the planet for a day, but because it orbits the planet, the position has been constantly changing up and down in the air, or every day between the northern and southern hemispheres.

Launching satellites is quite a professional job, even if the procedure of using a warship to launch satellites is countless times simpler than the traditional way. However, the most basic calculation of the operating orbit is inevitable, and Ye Fei has also received special training to know the difference between the two concepts.

"Chief, you mean that this broken ship has been protecting humans on the planet?" Hong Liang's pupils constricted, "Impossible, right?" ”

I don't know how many thousands of years this broken spaceship has been hanging here, and how good quality can it work until now?

"Just ask." Ye Fei didn't want to say it.

"Boss, you can't ask!" Yi Qi hurriedly stopped

"What?" Ye Fei couldn't help but be stunned, "Why?" ”

"If you ask now, it is tantamount to suing him that you two are not oracles!" Yi Qi explained.

Ye Fei was stunned for a moment before reacting: "Yes." That's right. Can't ask. "How could you not know how the City of God protects the natives?

Normally, he would not make such a low-level mistake, but in the face of these weak natives, although he did not have the slightest contempt in his mouth, he naturally gave birth to a high-minded mentality in his heart.

Ye Fei thought for a while and said, "It's still not right." Can ask. But there must be skill. ”

"What are you going to do?" Hong Liang asked curiously.

Ye Fei smiled slightly and did not answer. Instead, he lifted his visor and turned on the speaker: "King of the Treetops, let's get straight to the point, I'm from another god city." One of the purposes I'm here is to investigate what's going on in your Divine City. ”

"Another Divine City?" The treetops were stunned by this unexpected answer, but the feudal king, who had reigned for many years, was not bad, and quickly came back to his senses, "You are from another divine city, where is the ancestral divine city?" What is your relationship with your ancestors? ”

"I'll tell you all of this, but I have to figure out the affairs of the Divine City before I can sort out the ins and outs." Ye Fei said in a demonic seductive tone.

The King of the Treetops still hesitated to turn over his hole cards, and the wooden wheel shouted in dissatisfaction, "What are you still hesitating about? My dear brother, it only took the two envoys the fifth order to kill five thousand gray-skinned mongrels, which is five thousand! Mu Lun excitedly stretched out a hand with a wide spread of fingers, "Are you more difficult to deal with than five thousand gray-skinned mongrels?" The gods can destroy you with the touch of a finger! Think about it, my dear king, we have lost the Divine City for four hundred years, and now that the Divine Envoy has finally arrived, what are you waiting for? Wise, wise and decisive, do you want us to wait another 400 years? ”

The irony in Mulun's words was so heavy that he could hear it even if he didn't have a brainwave detector in his head.

The words of the wooden wheel pierced into the heart of the treetops like a soldering iron, and immediately angered the king: "Presumptuous, I am the king, I am the one in charge of the secrets of the royal family, and you don't need to teach me what to do!" His eyes were as wide as cowbells, and his chest was heaving like a nest of rabbits.

Echoes overlapped in the hall, the door slammed open, and a group of heavily armed guards rushed in with a dense pace.

"!" Ye Fei scolded hatefully.

These guys must have been lying in ambush outside the door for a long time, waiting for the king's orders.

Ji Xiaotong manipulated Gatling in a fit of rage, and the six barrels of the gun spun up quickly, aiming at the stone pillar above the guard.

The dull sound of gunfire echoed in the hall, the firelight flickered in the dark hall, the bullets made one nest hole after another in the stone pillars, peeled off large swaths of stone skin, and the broken gravel rained down on the heads of the guards, the flying stone dust sprinkled like mist, the whistling ricocheting bullets crisscrossed the hall, and several hapless guards were pierced through their armor by ricochets and fell to the ground in pain.

The King of the Treetops, with his eyes straight, kept yelling and gesturing back at the guards, but in the frenzied gunfire, his voice was no louder than a hum.

It wasn't until all the guards stopped in a daze that Ji Xiaotong stopped shooting. The frantically whirling Gatling ceased with the dull sound of the wind, and the last few bullets of chiseled gravel fell to the ground and the guards, smashing out a symphony of muffled and crunchy sounds.

There was a suffocating silence in the hall, and all the guards stood like marble sculptures, not daring to move.

None of them were fools, though they were ignorant, and they knew very well what would have happened if it had not been for the stone pillars that God had aimed the artifact in their hands.

The treetops breathed in the foul air full of gunsmoke, swallowed a mouthful of saliva with difficulty, and shouted in a trembling voice: "Whoever let you in, get out of here!" Although he knew that the guards were doing this for his own safety, he could not forgive them for acting without permission, and he had to calm the emissary's anger with anger.

Ye Fei and Ji Xiaotong looked irrelevant, as if what had just happened had nothing to do with the two of them.

The treetop couldn't help but breathe a sigh of relief, he was now afraid that the two messengers would make a non-dividing request. (To be continued......)
