In addition to these few features, there is also an ultimate feature: Soul Crucible.

When it comes to this feature, the system has a mysterious tone, and it can even be experienced by the cold front for free.

Leng Feng didn't want to experience it.

However, the system strongly recommended that Leng Feng was also idle, and it was free, so it opened this and made Leng Feng love and hate the terrifying space in the future.

The Soul Furnace is an alchemy furnace-style Dan furnace, just like the kind of Dan furnace of Lao Jun on the stage, with a big belly underneath and a small belly above, and there is a round door on both the big belly and the small belly.

This soul furnace is in the soul space of Leng Feng, and Xiao Hei's body is nearby, and at this time, Xiao Hei is looking at this big guy with burning flames suspiciously, his face full of curiosity.

Leng Feng followed the system's instructions and slowly walked towards the opening under the soul furnace.

I don't know why, looking at the wide open door, Leng Feng always has a bad feeling, and he walks cautiously.

But in the end, I couldn't resist the temptation of free and stepped in.

......

......

The inner space of the Soul Forge is a small world, very large.

When the cold front enters, it randomly teleports to the interior of a volcano in the small world.

A terrifying heat permeated the entire space.

At this time, Leng Feng was standing on a crimson disk, looking around, the crimson rock was in the center of the lava pool, surrounded by a boiling magma, and there seemed to be countless fiery red fish in the magma constantly gritting their teeth.

Leng Feng only stayed for a while, and many small beads of sweat appeared on his forehead, which kept dripping downward, but before they could fall to the ground, they evaporated into water vapor and floated upward.

However, the tiny beads of sweat did not wait for them to drip down, and they evaporated directly into water vapor on the face.

The temperature is getting higher and higher, if it weren't for Leng Feng always paying attention to the surrounding environment, he really wouldn't have noticed it, and the temperature rise would be like boiling a frog in warm water, little by little, slowly increasing.

"Is this the Soul Crucible? Leng Feng smiled faintly, this rising high temperature was indeed beneficial to the soul, but it was not so violent, Leng Feng could still withstand it, and even had some spare strength.

Then Leng Feng stood quietly, enjoying the heat.

However, just as steel needs to be roasted at high temperatures and forged by a thousand hammers, the Soul Forge is not only a terrifying environment, but also a powerful forger.

Knock knock!

Just when Leng Feng was concentrating on refining his soul power,

A sound of footsteps comes to mind.

Voices came from all directions, and Leng Feng curiously looked around for the source of the sound.

If you guessed correctly, this is the next opponent.

It just so happened that Leng Feng was also a little bored, and he felt the power of his soul, which was the soul power of the high-level guard, which was not bad, presumably the opponent arranged for him in this space was also of equal strength, so he could hone it well.

With this in mind, a three-meter-tall nine-armed Yama jumped directly from the crater above.

Originally, only Leng Feng was a slightly narrow red disc, but after adding a three-meter-tall nine-armed Yama, there was no gap, and Leng Feng retreated to the edge of the crimson disc.

When Leng Feng stabilized his body and looked at the nine-armed Yama in front of him, he was desperate in his heart.

The soul strength of the nine-armed Yama with red fangs in front of him far exceeded that of the guard level, and it should be the soul strength of the general level.

It stands to reason that tempering shouldn't be the same strength, right?

Generals fight guards, isn't this torture?

This thing looks a little scary...

......

Leng Feng muttered in a low voice, and stood in place in despair waiting for the nine-armed Yama to be killed.

The nine-armed Yama lived up to Leng Feng's expectations, each of the nine arms held a weapon, and took turns to give Leng Feng a blow.

Leng Feng was knocked to the ground, feeling a burst of pain.

After waiting for a long time, the pain was still increasing, but the death that Leng Feng was expecting still did not come.

Leng Feng's eyes widened, and he looked desperately at the hideous nine-armed Yama in front of him, and let out a final roar,

"What the hell。。。 ”

The nine-armed Yama's attack was extremely rhythmic, and the nine arms swayed back and forth, like chopping meat filling, giving Leng Feng a huge pain every time, this was not the kind of physical pain, but the kind of damage to the soul, the kind of pain that pierced the heart, and it couldn't recover for a long time.

Even though it was so painful, Leng Feng gritted his teeth and persevered, because gradually, Leng Feng found that every time he was attacked, he could feel that his soul was torn apart, and after healing, his soul strength would be a little stronger.

I don't know how long it took, Leng Feng's body has been blurred by the flesh and blood of the hammer, but Leng Feng has not lost consciousness yet, in fact, Leng Feng has experienced this tragic situation several times, and now he is even used to this pain.

After getting used to this pain, the increase in soul strength slowed down a lot.

Although he was a little ashamed, Leng Feng actually felt that the strength of this attack was too weak, and even looked forward to a more violent attack.

The Soul Forge did not disappoint Leng Feng, and the heat that had stopped rising was terrifying

The amplitude has risen sharply.

The cold front instantly felt the elevated temperature.

The sharp rise in high temperature not only brought a burning sensation, but also the pain of being burned by the high temperature, Leng Feng's body was scorched black in an instant, and after being scorched, he was smashed by the nine-armed Yama, revealing his delicate skin, and he was scorched again...

And so on and so forth.

That painful feeling came again, and the strength of the soul increased rapidly again.

Leng Feng not only groaned,

"Ah, cool。。。 ”

The interior of the huge volcano is filled with the cry of a cold front ecstasy.

However, it didn't take long for the cold front to adjust to the intensity of the pain again.

A hint of surprise flashed in the nine-armed Yama's eyes, and then he struck hard against a depression in the center of the red disc.

With the sound of the disc collapsing, Cold Front fell into the pool of lava.

The temperature of the blazing magma was several times the ambient temperature, and the terrifying high temperature scorched Leng Feng's delicate skin, and Leng Feng couldn't help but howl again,

"Ah, your uncle. ”

"Oh! I'll go. ”

"Huh... ”

There seemed to be something below the magma pool that attracted the cold front, and the cold front howled as it fell.

After falling for a long time, the cold front can already see the bottom of the magma pool.

Thump!

Suddenly, the cold front fell from the bottom of the magma pool and landed on a red disk again.

The red disc was the same as the upper layer, but it was twice as large, and above it was the bottom of the magma pool, as if sealed by a strange force, and not a single magma fell.

After looking around, another terrifying figure lay in front of Leng Feng.

Red Flame Shura.

Six meters tall, his huge body occupied the entire disc, and a terrifying aura permeated.

Leng Feng understood his fate, closed his eyes, and lay quietly in place.

......

......。

Although in the soul furnace, the soul is immortal and immortal, but the soul has a range of endurance.

I don't know how long it took, Leng Feng's soul finally reached the limit of bearing, and was spit out by the soul furnace.

There is no mistake
