In fact, at this time, let Han. Just as they leave Mars and return to Earth, it's not a good time. Because Mars, which is running around the sun in orbit at a speed of 24 kilometers per second, has run more than 100 million kilometers in the past 50 days, although the direction of Mars's revolution is the same as that of the Earth, but don't forget that the speed of the Earth's revolution is more than that of Mars, so in the past 50 days, the distance between the two has widened to more than 80 million kilometers.

If you add in the time it takes to return to Earth from Mars, by the time Prince Barnett arrived on Earth, it had already covered a distance of well over 100 million kilometers.

But even so, Han. Just as they must return to Earth.

Because Tang Feng didn't want to have others watching when he was transforming Mars. Even for the few unmanned probes floating in Mars orbit, Tang Feng will shield their observations with the help of the equipment of the Hope Base when necessary.

At the same time, with the power of the three main ion thrusters of the "Prince Barnett", if it continues to accelerate, the journey of more than 100 million kilometers will not take long, and if the acceleration rocket on the "Prince Barnett" is continuously used, the time taken to complete the journey of more than 100 million kilometers will be shortened.

All in all, Tang Feng didn't want to be watched by others when he was transforming Mars.

Now Tang Feng's prestige is extremely high, and what he says, as long as there is no fatal mistake, then basically no one refutes it.

And with the help of this return trip, the performance of the "Prince Barnett" can be further tested, and more data will be provided for the larger manned spacecraft to be built by the upcoming "Tinder Project".

Just go.

Two days later, the Nautilus took off again at Base Hope and returned with eleven other astronauts to the location of the Kunpeng and Eagle landing spacecraft. They were piloting the two landing ships back to the "Prince Barnett".

This process of taking off from the surface of Mars and returning to the mother ship is also a kind of detection, a big test of the entire landing operation on Mars. Without this process, the entire process of landing on Mars would not be considered complete.

After seeing the successful docking of the two landing spacecraft with the "Prince Barnett", and then the three main thrusters of the "Prince Barnett" began to operate at full capacity, pushing the huge "Prince Barnett" to leave Mars and head for the distant Earth, Tang Feng returned to the Hope Base again with confidence.

Now on the entire Mars, it is worth leaving Tang Feng alone.

But at this time, the star core body, which had been silent for about three days, finally came with a fluctuation again.

In fact, as early as after the star core body fell silent, Tang Feng had a very wonderful premonition in his heart, that is, his star core would not be silent for a long time.

Tang Feng didn't know where this premonition came from, but he just believed in it.

You must know that according to the information left by Old Man Andro, the process of promoting the planetary star core to the stellar star core is a long process. The higher the growth of the star core, the shorter the promotion process will be, but even the star core with high growth will have to be silent for at least fifteen days when it is promoted from planetary level to stellar level.

However, Tang Feng thought that his star core would recover in a short time. And this star core did not let Tang Feng's premonition fail, and after only three days of silence, it regained a stronger life fluctuation.

Standing in a certain hall of the empty Hope Base, Tang Feng couldn't hold back the ecstasy in his heart and laughed.

The Star Core was promoted in just three days, and the time it took was far shorter than the shortest promotion time that Old Man Andro had ever encountered. If Old Man Andro were still alive, he would be extremely shocked and ecstatic when he saw this situation!

Speaking of this star core, it is really amazing, the old man Andro condensed this star core back then, and its purpose was to save his life as a last resort. But it is estimated that even the old man Andro did not expect that the star core condensed at the last moment of his life turned out to be an amazing star core with high growth.

Not to mention anything else, in such a "remote" star field where the earth is located, a successor who has never even walked out of his home star, with the resources of his home star, in less than seven years, has forcibly raised this star core, which was not yet a complete body, to the threshold edge of the stellar star core, and now, this process of kicking the door has taken only three days!

Not to mention that Old Man Andro has never heard of such a thing, even if you look at the entire Star Alliance, such a thing is almost non-existent!

It's a pity that Tang Feng didn't know about these situations, and he was now completely immersed in the exploration of the upgraded star core.

At this time, Tang Feng had completely determined that the star core had successfully advanced to become a real stellar star core, because the star core space at this time had completely changed.

Some time ago, after the star core was promoted to level five and completely controlled the earth, the star core space completely changed into the appearance of space, but in the vast space, only the earth exists.

But now, it is no longer just one Earth that appears in space, and the current star core space has completely become the solar system.

That's right, the entire star core space is now a miniature solar system. From the red-glowing sun in the distance, to the eight planets, asteroid belts, dwarf planets, comets, and all sorts of small celestial bodies orbiting the sun

All the celestial bodies are centered on the sun, forming an extremely subtle but extremely balanced celestial system, just like the real solar system, and Tang Feng can even faintly see the stars in the Kuiper belt and the heliosphere in the distance

It's just that this solar system doesn't seem to be very clear now, and Tang Feng is not able to control this star system as freely as before. And in addition to the Earth, the Moon and Mars, the other astral Tang Feng can only be in a state of "can only be seen from a distance and cannot be blasphemed".

Obviously, this is directly related to the planet that the star core split completely controls. Any planet that is completely controlled by the split of the star core, Tang Feng can control it freely, and even on the earth, Tang Feng can control the transformation of Mars. But those planets that have not yet been controlled by the star core split, Tang Feng can't control them at all.

Perhaps, the sixth-level star core, that is, the first level of the stellar level, is like this! Only when all the important celestial bodies in the entire solar system are completely controlled, can this solar system be completely controlled by oneself! (To be continued.) )
