There is a distance of about one zhang between the two openings, which should be enough.

The bones between them were removed, not to mention Fengyun, and even King Kong could easily enter the inside of the skeleton head.

As his physical fitness became stronger and stronger, Fengyun no longer had to worry about his physical fitness being difficult to meet the requirements for the use of knife intent, and urged the knife intent more fully every time, so that its destructive power was guaranteed.

Therefore, the work place where Fengyun split the head of the skeleton progressed relatively quickly, and basically met his expectations.

According to his calculations, if nothing happens, at most, he could carve out a passage into the skeleton's head in an hour.

In other words, in an hour, the secret hidden inside the skeletal head will be revealed to him.

Thinking of this, Fengyun felt a little excited in his heart, but he quickly suppressed this excitement.

Although he had long been curious about the situation inside the skeleton head and wanted to explore it, he knew that the enemy was unlikely to sit idly by.

In other words, in the process of opening the passage into the inside of the skeleton head, there is a good chance that he will encounter a counterattack from the enemy, and the counterattack will most likely be very violent, after all, what he is doing now has created a real threat to the enemy.

Fengyun guessed right.

Just as he kept splitting the head of the skeleton, something suddenly appeared, it was a stone monster, not only on both sides of the skeleton, but also on top of it, forming a posture similar to outflanking him.

When these stone monsters appeared, it was obvious that they were not just trying to scare Fengyun, they attacked him shortly after they appeared.

At this time, these monsters showed great strength and bouncing power, one by one, like cannonballs out of the chamber, blasted towards the wind and clouds, tearing through the air and emitting a piercing scream.

Before they could really get close to Fengyun, Fengyun felt a strong wind rushing towards him.

If it were an ordinary person, he wouldn't have to wait for them to attack him, and that kind of wind pressure would be enough to kill him, and it would crush its body to pieces.

However, Fengyun didn't even frown.

These stone monsters might have been able to pose some threat to him before his physical fitness was greatly improved this time, but now that they were close to him, it was no different from sending him to death.

Suddenly, a dragon knife appeared above Feng Fengyun's head, but it was much smaller than the dragon knife he was using to slash the head of the skeleton, only about two zhang long.

However, it is also different from the first dragon knife, it has just appeared and turned into the appearance of a real dragon, and it is still constantly swimming around the wind and clouds.

In the process of swimming, it will also open its mouth from time to time, making a spitting shape, and every time it opens its mouth, it will spit out a cloud of mist-like things, and then the mist-like things will spread, enveloping the whole wind and clouds in it.

The scattered mist became thinner, like a thin veil of light, and every move of the wind and clouds could be clearly seen from the outside world.

It is this layer of light yarn that seems to be able to blow it away without a trace by a breeze, but it has extremely terrifying destructive power.

As soon as they came into contact with it, the stone monsters that rushed towards him quickly decreased in size, and in the blink of an eye, they disappeared without a trace, leaving only some fine grains of sand to fall to the ground.

However, it would also be incorrect, at least inaccurate, to say that they had disappeared completely, except that some sand was left behind, and that was red stone.

The red liquid contained in the red stone left a very deep impression on Fengyun, and after taking it, his physical fitness was greatly improved.

Although he already had a hunch that after he absorbed the fluctuations, their effect on their physical fitness would be greatly reduced, or even become dispensable, he decided to keep them.

Even if it turned out to be as he had a hunch, they had little effect on his physical fitness, but it didn't mean that they didn't have any value, and he could give them to other people, such as the people of the Huojiao tribe.

With their physical fitness, even if he diluted them many times, after taking them, their physical fitness would be greatly improved.

It may be more difficult to improve the strength of the Huojiao tribe in other aspects, but it is also possible to improve their strength by improving their physical fitness.

Therefore, from a certain point of view, he obtained the red stones in the bodies of these stone monsters, which was equivalent to mastering a shortcut to quickly improve the strength of the Fire Jiao tribesmen.

That's exactly what he wants to see.

The low strength of the people of the Huojiao tribe has always been a problem for Fengyun, because he doesn't know what kind of impact they will have if they are killed.

Of course, they got along well with him, and they couldn't bear to see them suffer casualties.

The red stones left behind by the dead stone monsters also fell along with the sand, but none of them actually touched the ground.

They will all be ingested in the air and put in the bag.

The stone monsters were killed a lot by Fengyun, but their numbers continued unabated, and it seemed that they could not see the fate of the forerunners before them.

In this regard, Fengyun did not feel any pressure.

If it was before he absorbed a large number of fluctuations and made his physical fitness greatly improved, he would have had some difficulties with them, after all, their strength was still relatively strong, but now he only had to accidentally put the knife away, and he didn't even want him to waste time focusing on them.

As soon as they got close to the sword intent he unleashed, they would be shattered in an instant.

As for the problem of the attrition of the sword intent caused by this, the problem does exist, but the impact on Fengyun is not great, and the consumption of the sword intent of those monsters killed by him is very small, and it will not be a burden on him at all.

In addition, in this way, his sword intent will also be sharpened to a certain extent, and he will become sharper and sharper. Overall, he had gained far more than he had lost, not to mention the large number of red stones he had obtained.

The number of stone monsters that pounced on Fengyun still declined, becoming fewer and fewer, which was completely expected by Fengyun, their number was large, but they couldn't resist him killing quickly.
