In order to upgrade the cost, the start announced the controllable nuclear fusion

Obviously, Ji Chengtian knew what was reported in the document without looking at it.

One week after the capture of the first "Kunpeng" air-space unmanned aircraft on the "Phoenix", news of the capture of the "Kunpeng" air-space unmanned aircraft continued to spread in the following time...

Prior to this, eight 'Kunpeng' fighter planes originally belonging to 'Phoenix' had been captured.

Here, Li Wei who heard the words shook his head, a wry smile appeared on his face, and then said calmly.

"It's not... In the twelve hours between yesterday and today, three more were captured..."

After hearing Li Wei's words, Ji Chengtian's eyes showed a bit of thought, as if he had found some pattern from it.

..... 0

"In this way, there are already thirteen planes...As expected, there should be a large number of 'Kunpeng' fighters lost in space without being captured...I guess, the 'Kunpeng' fighter planes of the 'Phoenix' are now 'There shouldn't be too many fighters, and there may even be none..."

Hearing this, Li Wei's eyes flickered slightly, and he nodded after a while, and finally said.

"Fortunately, with the trajectory information obtained from the capture of the 'Kunpeng' aerial drone, we have clarified the direction of the 'Phoenix'..."

Hearing Li Wei's words, Ji Chengtian turned around and walked towards the window, looking up at the darkening sky.

If he remembered correctly, the current 'Phoenix' has been out of contact for more than half a month.

After a short while, Ji Chengtian took two quick steps, as if he was making a decision, and then he seemed to have lost his mind, turned his eyes, and said directly to Li Wei.

"Old Li, order to continue. All the spacecraft will go straight to the track of the 'Phoenix' sailing at full speed regardless of consumption. I don't believe it. Where can this 'Phoenix' go!"

At the end, Ji Chengtian frowned.

"Understood! I'll go now..."

After speaking, Li Wei walked out of the office and gave orders.

So far, only Ji Chengtian is left in the office.

At this time, Ji Chengtian also understood,

This may be the last chance for rescue!

Chapter 406 UFOs in Low Earth Orbit

Here, Tang Zhenli, who had returned to the infirmary, was planning his return route on the desk beside the hospital bed under the reminder of Chu Wenqian.

One after another densely packed formulas and equations are all over the original white paper.

From time to time, Chu Wenqian, who was curious and came over to look at it, frowned.

The impression of Tang Zhenli in my heart is a little deeper...

Although she can't understand most of them, she can also guess that this is the formula for calculating orbits...

The question is, when did Tang Gong know so much about the field of astronomical orbits?

For a moment, Chu Wenqian looked at Tang Zhenli slightly with complicated eyes. This man...the more you get along with him, the more you can feel all kinds of horrors in him...charm, temperament, knowledge. .

"One Four Zero" and these traits are not static, every time, she can see new things in Tang Zhenli...

This feeling is like, this person is always improving, the most terrifying thing is that Chu Wenqian can't see the end of this kind of progress...

More importantly, this is just what she saw when she and Tang Zhenli spent a short time together...

If Tang Gong has been like this since he was a child, it is hard to imagine how much Tang Gong's brain and brain circuits are better than ordinary people...

No wonder sister Tianxian fell in love with Tang Gong at first sight since she was a child...

If that's the case, it's not hard to explain...

Who can't stand it?

No one can resist a man who exudes such charming temperament all the time...

For a while, Chu Wenqian's eyes on Tang Zhenli gradually lost her focus...

On the other side, Tang Zhenli didn't know that Chu Wenqian was talking about him inwardly.

At this moment, he is concentrating on planning the fastest route for the 'Phoenix' to go back.

That's right, plan the best route in space where there is no up, down, left, or right!

It sounds unbelievable, but Tang Zhenli knows that it can be done in theory!

And all of these are Tang Heguang's enlightenment to him when he was young.

As an expert in astronomical orbits, Tang Heguang is only in low-Earth orbit, but a sentence Tang Heguang said to Tang Zhenli when he was a child left a deep impression on him...

Seemingly boundless and boundless, there is also a direction in the vast and boundless space!

And the basis of this sentence comes from the cognition of human beings themselves!

This cognition is the cognition of the coordinate system!

On the surface of the earth, we usually mean up to refer to the opposite direction of gravitational acceleration, while left and right are defined according to the direction of self and rotation.

To put it simply, the approximate inertial reference system on the earth's surface is determined, and combined with its own attitude, it can define up, down, left, and right.

In space, there is a similar coordinate system.

For example, the most commonly used coordinate system in astronomy is the solar ecliptic coordinate system. The origin of this coordinate system is at the center of the earth, the x-axis is the straight line from the earth to the sun, the z-axis is vertical to the north of the x-axis, and the y-axis is the sum of the x-axis and The z-axis forms a right-handed Cartesian coordinate system.

Simply put, this coordinate system is to use the earth and the sun as reference objects to determine the specific position of an object in the solar system.

But what Tang Zhenli is doing at this moment is not using the solar ecliptic coordinate system. Now he is using his own estimation of the direction and speed of the 'Phoenix' deviating from the earth to determine a new coordinate system.

The reference objects of this coordinate system come from the earth and the moon. Although the reference range of this coordinate system is not as wide as the solar ecliptic coordinate system, it is more accurate.

In other words, Tang Zhenli is using this coordinate system to determine the specific position of the 'Phoenix' in the coordinate system he created at this time.

It might sound magical, but it's really doable!

And it takes a whole day to do this job. If Chu Wenqian hadn't persuaded him to sleep at the end, Tang Zhenli probably would have skipped this sleep cycle..

After going through this sleep cycle, Tang Zhenli woke up and started to calculate again from the blank paper.

Although Tang Zhenli's understanding of astronomical orbits is not very deep, with the help of the system, he can handle it with ease at this moment......

Finally, under the calculation of the half-day cycle, Tang Zhenli finally came up with a return route that only he could see!

If you want to say why only Tang Zhenli can understand it, then you have to talk about the coordinate system newly established by Tang Zhenli.

If ordinary people want to agree with this coordinate system, they have to go through a series of cognitive transformations, otherwise it is easy to substitute their own cognitive coordinate system into it.

In other words, Tang Zhenli will act as a human navigator during the next return journey, guiding the 'Phoenix' on its difficult return journey.

In the afternoon of the same day, the maintenance team of the power system also sent good news.

All three Qinglong power modules have been successfully activated and are turning successfully.

As soon as he heard the news, Tang Zhenli came to a cabin in the bow of the current 'Phoenix'.

In the case of damage to the main control room, the staff of the 'Phoenix' used the only cabin at the bow as a temporary command room.

And outside this cabin is the space-based laser cannon known as the "Sword of Slaying God" by the crew of the "Phoenix"!

In the past half a month, all the crew members of the "Phoenix" basically knew that the hero of Tang Gong's successful killing of the gods was the strange machine that was not paid attention to by everyone when the "Phoenix" took off. equipment!

That is the space-based 4.2 laser cannon!

Under this premise, the awe of the crew of the 'Phoenix' for this space-based laser gun has also accumulated over time.

After all.. it is such a small and unremarkable instrument that successfully saved all mankind at a time when all mankind was in crisis!

Fortunately, the position of this space-based laser turret is quite ingenious, and its size is small, so it did not receive much damage from the previous shock wave.

However, even so, some sailors still come here from time to time, just to admire the sharp weapon of 'Slaying God'!

But now that the cabin at the bow of the ship is used as a temporary command room, naturally fewer people come.

.................

Chapter 407 Discussing Civilization Invasion

In space about [-] kilometers away from the earth, in the cabin of the bow of the 'Phoenix'.

At this time, only Tang Zhenli and Chu Wenqian were in the cabin.

Prior to this, Tang Zhenli had ordered that he would stay permanently in this cabin during the return journey.

Sitting in a wheelchair, Tang Zhenli looked at the running status of the Qinglong power module displayed on the electronic screen with a calm expression, and was planning carefully in his mind.

In the coordinate system set by myself, the 'Phoenix' should be in that position now....

After a while, Tang Zhenli looked at the previously planned route and compared it with the newly calculated route in his mind.

After finding that the difference was less than 5.00%, Tang Zhenli's expression moved, and he twisted the control panel that controls the steering of Qinglong's power module.

At the same time, the bottom and rear of the 'Phoenix' emit a blazing flame, which is so eye-catching and remarkable in the cold and dark universe.

So far, after being lost for more than 17 and a half months, the long-suffering 'Phoenix' has officially embarked on the return route!

Afterwards, every two hours, Tang Zhenli had to re-determine the route to make sure that the 'Phoenix' was not off course.

According to Tang Zhenli's estimate, under the full operation of the three Qinglong power modules, the 'Phoenix' will return to low-earth orbit in no more than ten days.

............

Another ten days have passed, and the fishing boats on the Internet are still fermenting step by step, so that the official scene cannot be suppressed.

Although the enthusiasm about Wu Shaoying's fishing boat at this moment has not dissipated,

But netizens are now discussing more about the trace of the 'Phoenix'.

After all, it has been nearly a month since the 'Phoenix' lost contact, and the official search and rescue team has not received any good news.

For a time, not only the people of Dragon Kingdom, but even the international community, there were many voices criticizing the search and rescue team.

Some say that the search and rescue team is incompetent, some say that the search and rescue team is a vegetarian, in short, every good word..

To put it simply, during this period of time, netizens in Longguo and even the world have spent their time in abuse..

Either scold Wu Shaoying, or scold the search and rescue team...

Of course, it is not known whether there are people with ulterior motives behind this.

Longguo Science and Technology Department, Office of the Person in Charge,

During this period of time, Ji Chengtian had quite a headache.
