But it also instantly aroused Lin Feng's indomitable will, and he shouted violently:

"What's the big deal, isn't there just no tools and no energy?"

"Don't I still have hands and feet? I don't believe in this evil, and I can't even move my hands!"

Seeing that the flames were a little closer, and the scorching sensation was more obvious, Lin Feng gritted his teeth, squatted down and pulled up the sand violently.

"Huh?"

As soon as his palm touched the sand, Lin Feng frowned slightly, staring at the golden granular thing on the ground in surprise.

Although these particles look like sand, after actual contact, it is clear that this is not sand at all, but an unknown high-density metal particle.

This kind of metal particle is at least ten or more times heavier than iron sand, and Lin Feng exhausted his strength to dig out a big hole in the bowl, and his fingers were broken.

But he has no other way now, only this road to go dark, although it is a road with no hope, but it is much better than sitting still.

Even if you can't change the final outcome, you will at least do your best, and you won't regret it.

Fight!

At this moment, Lin Feng didn't have any other superfluous thoughts, and directly let go of his hands and feet and began to pull the sand with all his heart.

But even so, he still had the urge to explode into foul language.

He didn't know what the hell the golden sand was made of, not only was it ridiculously dense, but it was also very sharp.

Although he can't call himself any copper skin and iron bones, he has also been tempered by Qiankun True Qi, and has been transformed by the sharp energy in the Burial Sword Tomb, at least he is much stronger than ordinary people.

But after facing this sand, there was no difference from ordinary people, and in just a moment, Lin Feng's hands became scarred, and even Sensen's white bones were exposed.

The most terrifying thing is that the golden sand also contains a trace of sharp energy, just like the sharp energy of the Xuanyuan Divine Sword, but it is not so powerful.

But if the sharp energy contained in all this golden sand converged, Lin Feng believed that it would definitely not be weaker than the sharp energy of the Xuanyuan Divine Sword.

This sharp energy is very strange, unpredictable and like a maggot attached to the bone, destroying the palm of the hand all the time.

He even recklessly burrowed into the meridian qi sea of his body, and Lin Feng felt as if thousands of invisible swords were raging in his body.

The severe pain made Lin Feng's eyes tremble, beads of sweat the size of beans kept falling, and his lips were like cracks of dried dead wood.

But Lin Feng's extremely painful face had a firm expression, as if he had blocked his pain nerve reflex arc, and he only remembered one thing, and that was to dig up these golden sand in front of him.

He's going to fight this golden sand to the end!

The hands waved mechanically, as if they were tireless.

......

An hour later, something unexpected happened to Lin Feng.

The golden flame actually stopped moving forward, stopped in a special position and stopped moving a single inch.

This distance is exactly the limit that Lin Feng can withstand the high temperature.

After that, whenever Lin Feng's endurance increased, the flames would move forward with him, and he would not stop until he reached his limit again.

Two hours passed, a day passed......

Lin Feng, who had been pulling sand, stopped his movements.

Although he looked particularly haggard at the moment, his eyes became three points brighter than before.

After a long time of pulling golden sand, Lin Feng has mastered a lot of basic information.

First of all, as expected, the purpose of this world's imprisoning of his energy is to stimulate his physical potential without relying on any external forces.

The effect was obvious, and he could clearly feel that his physical strength had improved a lot.

Second, the golden flames didn't engulf him instantly, it moved forward to force him to pull the sand.

And the so-called sand is only a façade, but in fact it is infinitely useful.

Being able to temper his body well is only part of the story.

And the sharp energy contained in the sand is the most important thing.

Because when he pulls sand, this sharp energy penetrates through moisturizing things silently, and finally transforms into his own energy.

On this day, he could clearly feel its existence, stored in the sea of qi.

This kind of energy is different from the previous Qiankun True Qi, not only is it more condensed than it, but it is also extremely sharp, and it is estimated that it can be invincible and indestructible to a certain extent.

With this kind of energy in the sea of qi, it is equivalent to being a peerless divine weapon in itself, if others know the mystery of this, even if they pay a big price, they will come here to cultivate.

Another advantage is that when he was digging the sand with all his heart, the feeling that his body was about to be burned by the high temperature actually weakened, and it was faintly within the range of his bearing.

Maybe it's because it's getting stronger, or maybe it's because everything of this kind seems to be arranged in the dark, and it's a ridiculous coincidence.

Although he had only dug a small pit with a diameter of about one meter for a whole day, he seemed very happy, at this moment he was no longer trying to save his life, but also to improve his strength, his mentality naturally changed.

Looking at the golden sand on the ground, Lin Feng started again, trying his best to pull the sand.

In the blink of an eye, another day passed, and Lin Feng did not stop pulling sand at all, all kinds of signs showed that this was an excellent place to cultivate, and it was exactly what he had expected.

But there is also something different, that is, Lin Feng underestimated the sharp energy contained in the golden sand, with the improvement of his physical body and the increase in the energy in his transformed body, the sharp energy contained in the sand is also increasing, and he has been maintaining a balance at the limit of his own bearing.

In this regard, Lin Feng not only did not panic, but became more and more motivated.

Because he could feel that any punch he made at the moment had no less power than the previous use of Qiankun True Qi, which was just the ability of the physical body.

If this kind of transformed energy is added, it will definitely be impressive, and if this energy is integrated into the Xuanyuan Divine Sword, it will definitely be twice as powerful.

Lin Feng was going to be so happy that he couldn't keep his mouth shut.

Although he doesn't know when this test will end, as long as it is not over, he will do his best, and he will definitely not let go of this opportunity to improve his strength.

There is no night here, it is always a scorching day, just like the tireless Lin Feng.

One day, two days, three days, four days......

One month, two months, three months......

......

Lin Feng had already ignored the passage of time, he only knew that the energy in the sea of qi was rising and was full.

Under the influence of the sharp and domineering energy, the sea of qi became extremely powerful and vast, which was more incomparable than before......
