Sure enough, they didn't pay much attention to the previous reminder, and most of them were still tirelessly trying to cultivate immortals.

Those learning giants are slightly better, after all, those knowledge is also very attractive to them. But those aristocrats really barely read any mundane knowledge, and have been indulging in cultivation.

They have rich and powerful people in their families, and hundreds or thousands of slaves are waiting for them, so why bother to learn those mathematical materializations. Of course, it is still to cultivate immortals, make your body better, and you can also pamper more servants, let yourself live longer, and enjoy yourself for a few more years, this is the most important thing.

When Li Nan saw such a scene, it was inevitable that he would regret it, he just chose the group with stronger luck at the beginning, but now it seems that those nobles are really unbearable.

Even the prince of Zhao State, who is known as the country of tigers and wolves, is also practicing hard at this time, and the only difference from other nobles is nothing more than remembering the appearance of some ordinary knowledgeable people.

It is estimated that it is the idea of cultivating by himself after turning back and going back, and then collecting these learned knowledge to his own country and letting them work for him, in this way, it is not the idea of cultivating immortals and strengthening the country at the same time.

However, their idea was doomed to fail, that is, because they were now on this Tongtian Tree, the aura in the sky was already slightly richer than below, and Li Nan's cultivation had overflowed a lot of aura some time ago, so they were able to practice to get started.

When they return to their homes, it will be very difficult to go further, and it is estimated that they can only absorb a trace of spiritual energy if they are tired and tired.

As for other cultivation methods other than absorbing the aura of heaven and earth.

Among the basic cultivation methods, there is indeed a way to absorb the essence of the sun and the moon.

But one thing to know is that not all planets have moons, and not all stars have sunshines.

Stars are divided into many levels, either by color or by size, but neither of them is particularly accurate.

For example, in terms of color, in theory, red stars should be smaller than red-yellow stars, yellow stars should be smaller than white stars, white stars should be smaller than blue stars, and blue stars should be smaller than purple-black stars.

However, there are some exceptions, such as a star that may be many times larger than a blue star, but its color is likely to be red.

However, there are not many such exceptions, and if these few exceptions are removed, the above color division can barely be considered correct.

The same is true for by size.

However, the existence of the sun and the moon is not distinguished by the size and color of the stars.

Ever since Li Nan knew that the goblins on the cultivation planet could absorb the Sun Essence and Moon Hua for cultivation, he was very curious about what the sun and moon on the cultivation planet looked like, so he secretly purchased a lot of small satellites from the Tunguska Empire.

About ten days ago, the light watch received the surrounding situation of the cultivation planet transmitted by a small satellite.

This cultivation planet is very special, and it is completely different from the planet where the spirit crystal was found on the side of the Tunguska Empire.

How to put it, he is a bit against the normal theory of galaxies, which is generally the planets revolving around the stars, which has almost become the norm of the universe.

But it's not, he's the sun and the moon revolving around the planet of practice.

That's right, this is a very standard planetary center galaxy, this is also the first time Li Nan has seen a galaxy like this, and in the history of the Tunguska Empire, this kind of galaxy has never been discovered.

The difference between the size of the Sun and the Moon is not too big, and the Sun and Moon here are completely different from normal stars, they are more like a half-energy body.

Normally, the vast majority of stars are nuclear fusion, and they all belong to nuclear fusion radiant energy, but the sun and the moon that orbit the edge of the cultivation planet are not nuclear fusion.

Just looking at the photo, it looks very similar to a semi-energy body, that is, half of it belongs to matter, half belongs to energy, similar to something in the form of spirit crystals.

A galaxy in this form is obviously out of place in this universe.

Abrupt like an outsider.

Li Nan didn't expect so much for a while, but through these space pictures taken from him, he understood that in any other planet, any normal galaxy, even if he could cultivate, there was no way to absorb the Sun Essence and Moon Blossom.

Therefore, at present, it is completely useless for these nobles to practice on the Tongtian Tree, because Li Nan will not let them stay here for long at all, and at most they will have to send them down for a few months, and a few months is enough for them to learn some knowledge, if everyone learns a little.

In a month's time, with their qualifications and such a thin level of aura, they have basically entered the door, and they are extremely talented in the early stage of qi refining.

But is it possible?

It's impossible, judging from their basic twenty or thirty years old, the meridians have already been blocked, and it would be good to be able to draw qi into the body in a few months.

Introducing qi into the body, in fact, in essence, the gap with ordinary mortals is not too big, at most, it can only be said that the body is a little healthier, prolonging life or something, it is simply impossible.

However, Li Nan didn't remind them that they had already said it before, what could they do if they didn't listen? He just ordered the puppets placed in the Langya Pavilion and told them that after staying here for a limited time, they would go to the Tunguska Empire.

Li Nan was so happy that he was singing today, and happily went to the scheduled aviation ship.

Along the way, most people were silent, almost silent, one by one, without any conflict.

"Please consciously lie down in the nutrition cabin, the speed of light flight is more bumpy, so please lie down in the nutrition cabin to avoid bumps, automatically enter the sleep state, and when you reach the destination, we will wake you up!"

Because this has always been done, no one raised any doubts, and each of them lay down safely in their respective nutrition cabins.

Of course, the real reason can't be just to prevent bumps, but there is no doubt that it is much safer to enter the nutrition cabin than to wear a seat belt.

Li Nan also went in in a proper manner, anyway, it was less than two hours, and it was considered to be a sleep, speaking of which, Li Nan had not slept for a week, and since the last retreat, he had not slept once.

Although I am not sleepy, it is quite comfortable to lie down, close my eyes, and seal my divine sense.
