The formation trapped in this star system and unable to leave is rushing in the direction of the wormhole, and the other members of Formation 51 have been evacuated.

Obviously, there are almost no worries on the side of the comrades, and now there are only three people involved in the danger.

But!

The biggest problem is that no one knows when the enemy will come, when they will encounter, and how many masters the other side will have.

To some extent, the mission of their trip has been completed, and the trapped formation has been rescued, but can Qin Yan give up the big piece of fat in front of him for safety reasons?

Just now, the information detected by the probe instrument revealed that there is a surprising amount of treasure inside this star.

Gray crystal.

Above Mingjing, Caijing, and Black Crystal, it is the only main gun that can drive a four-star warship or more, and can exert the full power of the giant planet-level railgun, and can send out an attack at the level of time power, which is an energy crystal as the most important strategic resource.

It can be said that for any empire, Gray Crystal is a treasure-level existence.

Take the Lyra Empire as an example, don't look at the Lyra Empire has many five-star warships, but in fact, these five-star warships are only much stronger in firepower than four-star warships, but they are only improved in 'quantity' but not in 'quality' - is it because of lack of technology?

Of course not!

Once the main cannon of the five-star battleship is activated at full strength, it is enough to burst out with combat power comparable to that of the Heavenly Martial Seven Heavenly Martial Artists, and it can unleash an attack similar to the law.

But the fact is that all the five-star warships of the Lyra Empire are not equipped with Gray Crystal.

To put it bluntly, unless faced with the invasion of the Empire, Gray Crystal will never be used, and will always be stored in the treasury as the ultimate strategic resource. There is only one reason for this, and that is that the number of gray crystals is too small, even though there are not many energy crystals.

The expeditionary force has a large number of formations every day, searching for resources in the unexplored universe, a large number of energy crystals are discovered every day, and a large number of energy crystals are transported to the country from the five major bases every day, becoming the power of various military and civilian equipment throughout the empire, this number is very amazing.

However, the vast majority of energy crystals have only the lowest layer of crystals, and the number of deposits with color crystals has decreased significantly, and even fewer have black crystals.

As for Grey Crystal......

There may not be one in 10,000 energy crystal mines, and the most important thing is that even if there is a chance of less than 1 in 10,000, the number of gray crystals, which is the core of the deposit, will be pitiful.

In the last mission, Qin Yan's luck was not bad, he actually came across a deposit containing gray crystals, but how many gray crystals were in that deposit?

He mined only a few hundred kilograms, and the rest that was not mined was at most more than 1,000 kilograms.

Take a five-star battleship as an example, once its main gun fires at full strength, the energy consumed is extremely amazing, and almost a hundred grams of gray crystal are required for an attack. A few hundred kilograms of gray crystals sounds like a lot, but once equipped in a large number of fleets, hundreds of five-star warships are launched at the same time, and they are used up in a few moments.

Compared with a large-scale war, where tens or even hundreds of millions of warships are often involved, the amount of gray crystals consumed will be astronomical.

This is also the reason why all countries use gray crystal as a strategic resource, and they will never use it unless it is invaded.

Because once the real war starts, the number of gray crystals will never be enough.

Right now!

Inside this star, I don't know why, there is an astonishing number of gray crystals: the instrument can detect the emission of gray crystals just outside the star!

It is important to know that only the inner part of the star will be solid under tremendous pressure, so it is certain that the gray crystal exists in the inner core region of the perseverance. With the diameter of this star of more than 1.4 million kilometers, the gray crystals in the inner core region can be detected outside the star, and you can imagine how amazing the number is.

100 tons?

Kiloton?

10,000 tons

Definitely more than that!

If Qin Yan was asked to give up so many precious strategic resources, it would be absolutely impossible - it would be more painful than cutting a piece of his flesh.

More than an hour later, the three people who had recovered their spiritual power after attracting the power of the stars and being able to nourish the Yuan Shen were already radiant.

"Senior, how many elixirs do you have on you to restore the true yuan?" Qin Yan asked.

"Less than fifty Lingyuan Pills."

These pills were all brought from the earth, and Hou Qing thought about it and said, "In addition, there are 20 spiritual liquids allocated by the base. ”

Since the energy required by a martial artist comes from the aura of heaven and earth, in the battle of the universe and space, there is no aura of heaven and earth to absorb. Therefore, the military will distribute a certain amount of spiritual liquid every time the team goes out on a mission, and the so-called spiritual liquid is actually purified and condensed by the spiritual energy of heaven and earth, which is very pure and almost does not need to be purified, and has an effect similar to the elixir that replenishes the true element.

According to different cultivations, the amount of spiritual fluid distributed by each person before performing the task is also different, such as Hou Qing distributes ten copies each time.

It's just that he didn't use the spiritual liquid distributed by these two missions, and he kept all of them.

"Nina, how many do you have?" Qin Yan asked.

"More than a hundred portions of spiritual fluid."

"Almost."

Qin Yan's face was rarely solemn, and he said, "Whether it is entering the interior of the star next, or if you are unlucky enough to encounter a battle, use the True Yuan as little as possible." Now, give me the elixir and the elixir, and you each keep a little of it...... Anyway, you have to fight - go! ”

As soon as he finished speaking, Nina immediately released a law that enveloped the area where the three of them were.

In order to save the power of time and space as much as possible, the three of them stood together, and the area shrouded by the law was very small: the time flow rate in this area was reduced by as much as twenty times, but Qin Yan was not affected, which was equivalent to disguise, and the stellar space power in this area had reduced their erosion rate a lot.

At the same time, Qin Yan's dimensional space was activated, and in a smaller area, the three of them were enveloped in a twisted sphere space.

In order to keep the speed of the three of them at the same pace, in order to save energy as much as possible, and to make the speed reach the fastest level of passage for the three people, Nina, who was the strongest in cultivation, flew with Qin Yan, while Hou Qing flew by himself, and the figures of the three quickly disappeared into the burning flames outside the star.

Until you actually enter the interior of the star, you will never know what is really going on inside.

High temperature?

There is a dimensional space of its own, and the high temperature has no effect on the three of them, and what is really terrifying is the massive space power that fills the inside of the star.

The dimensional space is not truly indestructible, the so-called absolute defense is still relatively speaking, when eroded by the endless power of space, the dimensional space will be broken almost every few seconds as time passes, and then Qin Yan will release it a second time.

Does the gravitational pull of a star's inner core make them fly faster?

The answer is yes.

But!

The current situation of the three of them is that they want to use their own space rules to form a defense, and move forward against the massive and tyrannical space power inside the star. It's like moving forward in mud or paste, causing the gravitational pull of the star to be far less than the drag caused by the force of space, so that the speed of flight is many, many times slower than in space, or even on a planet where there is air resistance.

For example, Hou Qing, with his current strength in space, can fly at a speed of more than a hundred times the speed of sound, and under the influence of gravity and air resistance on the surface of the planet, the speed will drop to seventy or eighty times the speed of sound, but here his speed is only a pitiful five times the speed of sound.

The flight range of five times the speed of sound in a day is less than 150,000 kilometers.

In other words, with the diameter of this star of 1.5 million kilometers, it takes at least five days to get out of the very small stellar nucleus.

Nina, who flew with Qin Yan, was about the same speed as him, and the flight consumed true yuan, so they were bound to consume a lot of energy during this time, and in the absence of heaven and earth aura inside the star, they could only rely on pills or spiritual liquid to replenish it.

In fact, Hou Qing and Nina did not consume much elixir and spiritual liquid, and Qin Yan was the real big consumer.

Resist the erosion of the power of space in the outside world with the rules of space, and the release of the rules requires spiritual power, Qin Yan can't be busy at all, because the speed of consumption is faster than the speed of recovery, so the matter of resisting the invasion of the power of space is done by him and Hou Qing in turn.

Why not include Nina?

Because Nina has another job, which is to use the law to reduce the power of the outside space and release the erosion speed of the rule to them.

Fortunately, the power of the law is even more powerful, and each release lasts for a long time, otherwise Nina alone would not be able to bear it.

After consumption, it must be replenished, how to replenish here?

There is only one way, that is, Qin Yan uses the power of the stars to help himself, Hou Qing, and Nina nourish their divine thoughts: in this way, Nina is responsible for using the law to weaken the erosion of the outside world, Qin Yan and Hou Qing are responsible for resisting the erosion, and Qin Yan has to help the three of them recover their mental power.

Although being taken by Nina to fly does not need to consume the power of the stars, it helps the three of them recover their mental power, and the energy consumed far exceeds that of flying.

So every time the power of the stars dropped to about seventy percent, he had to take an elixir or spiritual liquid.

But!

His energy comes from Zhou Tian's star power, and the quality of the power of the stars is far above the true element, although it is said that the energy of heaven and earth aura can also be transformed into the power of the stars, but due to the different levels of quality, the pill that could originally be transformed into ten true yuan is only one of the power of the stars, so you can imagine how fast he consumes the pill.

They are inside the stars, so why not absorb the power of the stars?

That's right, this is the interior of the star, and there is only the star power of the star here, and the other kind of star power that is used for balance, and the star power of the cold attribute cannot enter the star at all. If he just absorbs the power of the stars, there is only one result, and that is that he will be burned alive!

Every moment is torment, not because of the consumption of elixir and spiritual fluid, according to the amount of elixir and spiritual fluid they have, this task can be completely completed.

The question is, what happens if the enemy arrives early and encounters inside the star?

Fortunately, there were no accidents during the flight, and the trio finally reached the inner core of the star on the sixth day......
