The harsh environment of this trial world today is mainly due to the heat.

This kind of heat increased Chu Nan's aura loss, but fortunately, after he successfully modified the method of the Spirit Sea, he didn't have to worry too much about this aspect.

As we move forward, the world gradually opens up, but the land is still barren and there is nothing.

Although this kind of movement will increase the loss of aura in Chu Nan's body, with his current absorption rate of aura, there is no need to worry about the lack of aura.

In the blink of an eye.

He's already gone a long way.

As he went, he was constantly thinking about how to break through this stage.

Just thinking about it, he didn't think of a good way.

Looking at the red sun in the sky, Chu Nan wondered if it had something to do with the blazing heat emanating from this red sun?

Thinking of this, he tried to sense the red sun in the sky, and immediately felt the amazing heat energy emitted from this red sun.

This heat energy seems to be absorbable.

It's just that when he tried to absorb the heat energy emitted by this wisp of red sun, his entire body seemed to be ignited by fire, the trunk of the tree turned red in an instant, and the branches of the tree were even more ablaze!

This immediately startled Chu Nan.

He didn't expect that just absorbing a wisp of heat energy would bring such serious consequences!

A strong crisis instantly filled his entire mind.

Let him realize that if he fails to deal with this wisp of heat, then he is likely to be directly incinerated by this wisp of heat.

Immediately, he did not dare to have any hesitation or hesitation.

Immediately control the aura and tree power in your body, wanting to extinguish the scorching heat caused by this wisp of thermal energy.

It's just that when his aura touched this wisp of heat, instead of extinguishing it, it caused the aura itself to become extremely hot.

Tree forces are also ineffective.

Snort!

Time.

Not only did the flames burn on his branches, but even on the trunks of the trees, flames rose up, turning him into a fire tree completely!

And the burning of these flames brought him great pain, making him extremely painful all over his body, inside and out.

But for now, he didn't care about the pain of these flames, he just wanted to put them out as soon as possible.

After all, these flames not only caused him pain, but also caused him a crisis, if he was allowed to burn like this, it would not be long before his entire body would be burned, and then his trial would end early.

"Damn it!"

In an emergency, he tried many things.

However, the effect was not too good, and the flame on his body was still not extinguished.

In this crisis, he didn't have time to think slowly, almost using whatever method he thought of.

Gradually, he used the method recorded in the Demon Emperor Inheritance, and regardless of whether it was effective or not, he used it first.

Call!

The method he used was a kind of magical compression.

Now he's trying to compress the heat in his body.

Airplanes!

With the compression, he was pleasantly surprised to find that it worked!

After the heat energy in his body was compressed, it quickly contracted into a piece, so that the flames burning on his trunk and branches quickly merged into his body and was somewhat relieved.

However, when these heat energy shrinks into a piece, the power it emits is even more terrifying and amazing.

Although it was in Chu Nan's body and was not exposed, the pain it brought to Chu Nan had increased dozens of times in an instant.

The crisis is even stronger!

It's as if there's a bomb in the body that is about to explode at any moment.

Chu Nan had no other way now, but around this bomb, with tree power and aura, he forged a huge ball and wrapped it.

This also minimizes the damage caused by heat.

For his rash absorption of Chiyang thermal energy this time, Chu Nan also realized that it was too hasty.

almost ended the trial early because of this red yang thermal energy.

Of course, the current crisis has not been resolved.

There is still a great deal of danger.

Fortunately, the heat energy after compression, although the power is stronger, under Chu Nan's wrapping, it has not caused any more damage to his body.

Chu Nan tried to expel the heat energy from his body.

It turned out to be a failure.

He tried many ways, but he couldn't get the heat out of his body.

That's it.

Days passed.

This heat energy gradually stabilized.

There was no longer a threat to Chu Nan's body.

At the same time, his body, which had been damaged by the heat earlier, was also restored in the repair of the tree power.

Tree power not only has a strong vitality, but also has a certain healing effect.

Although the body recovers, the heat energy in the body is always a hidden danger.

It seems to be stable at the moment, but Chu Nan knows that once he is stimulated, the heat energy in his body is likely to explode!

And as he went, the temperature of this world seemed to increase as he went, so that he had to stop, not daring to continue walking, for fear that the increase in temperature would stimulate the heat energy in his body, so that the heat energy would explode.

Fortunately, the heat energy in his body, wrapped in the ball formed by the tree power and aura, became more and more stable, and in the end, the entire ball actually changed to Chu Nan's surprise.

The entire sphere, under the influence of heat energy, gradually turned red, and it was as if it had become a heart, in Chu Nan's body...... Beating!

There are also silk threads formed by a lot of heat energy, like blood vessels, diffusing from the sphere and gradually connecting with Chu Nan's body.

This scene greatly surprised Chu Nan, he didn't expect such a change.

Under the connection of these silk threads, there is a continuous flow of heat, which is transmitted to his body along the silk threads, so that his trunk and branches, under the flow of these heat streams, become dark red!

Even on one of his branches, a dark red leaf grew!

This leaf is dark red all over, with clear lines, and it contains a terrifying fiery power.

And at the moment when this leaf took shape.

Here in Chu Nan, he directly broke through the first stage and entered the ...... Phase 2!

This made Chu Nan completely stunned.

He didn't expect that the absorption of this red yang heat energy would make him a blessing in disguise, thus breaking through the first stage!

In fact, there are many ways for dryads to break through the first stage.

Because the key to breaking through the first stage of the dryad is to have the power to attack.

Prior to this, although a lot of tree power and aura were born in Chu Nan's body, these could not be used as his offensive power.

Now, after absorbing the Chiyang Thermal Energy, by mistake, this wisp of Chiyang Thermal Energy absorbed by him has become his offensive power, thus breaking through the first stage.

Chu Nan was very glad about this......

He knew that this method of absorbing the heat energy of the red sun would inevitably be a dead end for others.

If he hadn't used the compression method in the Demon Emperor Inheritance to compress these heat energies together, his body would have been incinerated directly under this powerful heat energy.

Fortunately, the heat energy he absorbed now became a kind of power in his body, allowing him to successfully break through the first stage.

This made him happy, but also saw hope, feeling that his growth rate should be relatively fast among these people.

He felt that if he continued to grow at this rate, he might be able to catch up with some people and get more blessings from the Divine Tree.

With the breakthrough of the first stage.

He can absorb aura again to grow.

However, the amount of spiritual energy required in this second stage is far more than in the first stage......

Even with his current aura absorption speed, it seemed a little slow.

If Chu Nan was starting the trial at the same time as those others, then at his current speed, it would be difficult for others to be faster than him.

However, he started much later than others, and if he wanted to catch up with more people, he also needed to use faster methods to absorb the aura.

This is the end of my mind.

Chu Nan decided to move on!

Now, as he moves forward, he also finds that the temperature is growing.

As the temperature rises, the aura is also a little different.

These auras are blazing, and after being absorbed, they tend to grow better than the original aura.

When Chu Nan traveled a long way in a company.

The temperature of the surrounding aura has reached an extremely terrifying level, but fortunately, Chu Nan has already stepped into the second stage.

If it was still the first stage, with his body, he would not be able to withstand such high temperatures at all.

Meanwhile.

Chu Nan was still here, and saw an incomparably huge ancient castle, standing on this barren land.

The entire castle is extremely huge, with a magnificent and majestic atmosphere, and the whole body is red, and it seems that it has also been affected by the high temperature in this area, making this ancient castle also exude a terrible high temperature, which seems to distort the air.

Because this ancient castle was so big, Chu Nan looked extremely small in front of it.

At the same time, this is also the first building that Chu Nan has seen in this trial world!

From a certain distance, Chu Nan observed the ancient castle and did not dare to approach.

It was really that the temperature emitted by this ancient castle was too high, and if he approached it rashly, Chu Nan was worried that his body would not be able to bear it.

And the appearance of this ancient castle also made Chu Nan realize that there must be differences in this area.

After thinking about it for a moment, he decided to put down roots here and make observations.

As he moved, the roots of the tree under his feet shrank to just over a meter long, but when he decided to take root, the entire root immediately grew and plunged deep into the ground.

"Huh?"

When the roots of the tree under his feet spread deep into the ground, he suddenly felt a hot breath from underground.

After this hot breath melted into his body along the roots of the tree, his body suddenly grew significantly.

This immediately made his eyes light up.

He found that the growth brought to him by this hot aura under the ground was far beyond the growth after he absorbed the spiritual energy.

He immediately began to attract the heat beneath him.

It's just that this kind of hot air is relatively rare.

After some research, he found that the heat was actually coming from the ancient castle in front of him.

This immediately made him feel excited.

Try to move forward.

However, the temperature here is too high!

Every time he moved one meter forward, the temperature would increase exponentially, and Chu Nan could no longer move forward after barely moving forward two steps.

Over here......

It was already the limit of what his body could bear.

If he went any further, his body would not be able to bear it, and he would be in danger of death.

This made Chu Nan's heart feel as if he was scratched by a cat, as if he was looking at a bunch of delicacies in front of him, but he could only smell the taste and couldn't get close to taste it.

In desperation, Chu Nan could only think of ways from other aspects.

He found ......

These hot breaths did not come from the castle itself, but from the underground of the castle!

It seems that there is something under this ancient castle that makes it so hot here.

This gradually made a bold conjecture gradually emerge in his mind.

"If you think of this castle as a dryad like me...... Then the location where he is rooted now is the most conducive to growth in this area!"

"When he takes root there, he absorbs all the heat in this area, and I can only absorb some remnants of the heat here......"

"If I can take its place and take root in it, then in the heat of this area, I may be able to ...... Break through the second stage as fast as you can!"

Chu Nan's heart was pounding.

Although he didn't know how much heat he could absorb in the castle at one time, from what he felt, ninety-nine percent of the heat in this area was concentrated under the castle.

This couldn't help but give him hope for a quick breakthrough in the second stage.

It's exciting.

It's just that the temperature emanating from the castle itself is too high for him to get close to, and it is completely impossible to replace it.

For a moment, Chu Nan's mind was spinning rapidly.

It's rare to have such an opportunity in front of him, and there is no reason for him to miss it.

"If it doesn't work on the ground, then find a way underground!"

Chu Nan tried to increase the length of the tree roots with the power of the tree, trying to make the roots extend all the way from under the ground.

Phew!

As the tree's strength increases, the roots grow rapidly, but they are also extremely strong and sharp, easily penetrating the rocky soil beneath the ground, all the way to the bottom of the castle.

At the same time, the temperature under the ground is not as high as on the ground, so that Chu Nan's tree roots can move forward smoothly.

However, after traveling a certain distance, Chu Nan's roots reached their limit.

It can't go any further.

This couldn't help but make Chu Nan frown.

As the roots of the tree extended, the hot air in front of him also appeared a terrifying surge, which made him feel it extremely clearly.

He knew he was right.

As long as the roots of the tree can be extended, it can absorb more of the hot air.

on this.

Chu Nan was ruthless in his heart.

He did not hesitate to overdraw the strength of the tree, increase the extension of the tree roots, and even let his body directly shrink from more than three meters to more than one meter long, so as to extend the roots of the tree.

In this way, under his maximum extension of the roots, the roots quickly spread forward.

As it continues to extend, more and more hot qi is absorbed by the roots of the tree, prompting the rapid growth of Chunan.

When the roots of the tree spread some distance forward again, suddenly ......

Rumble!

One hand......

Suddenly grabbed the root of the tree that Chu Nan extended forward!!
