It is the same as the Tiangong mechanism that I encountered in the Tomb of Shaman Soul.

Although some professions are not as famous as formation masters, the things they create are no weaker than formation masters.

Otherwise, it would be impossible to establish one's own business and continue the inheritance for who knows how long without exhaustion.

"There must be something that affects the mind and maintains the alternation of cold and heat in this room, giving people such a real illusion!"

It's not a formation, but it can produce such a real illusion that one can't even tell the difference between the soul and the body. It should be maintained by some treasure or special power, just like the formation needs spiritual energy to drive it.

"defect!"

After understanding what was going on, he returned to his physical body mentally and carefully touched the walls and floor of the Ice and Fire House with his fingers.

Not long after, a book appeared in my mind.

"I see……"

After reading the contents, Zhang Xuan smiled slightly and understood.

"Origin Fire Ice Field, first there must be Source Fire, and then there must be ice field. Only when the two merge together can such a strange phenomenon occur...According to the direction, it should be here!"

After measuring around the room for a while, I came to a corner, made a fake, and clicked several times in succession according to several directions.

Click!

As the sound of the mechanism opening sounded, a hole appeared in front of me.

It's a dark bottomless pit, I don't know how deep it is.

"Go down and have a look!"

When others face this kind of pit that they don't know the depth of, they can't do it even if they think about it, but he can fly without any fear.

The body jumped straight down. After falling for a while, it flew once to slow down the speed. It didn't consume much, and it landed for several thousand meters. Only then did it land on the ground.

It is an underground cave, extremely spacious, with no end in sight. Directly in front of it is a small pool, only about two meters in diameter, but like the yin and yang fish of Tai Chi, half of it is flowing with hot magma and the other half is floating with ice.

The surrounding spiritual energy was very active under its influence. It was very good in the palace before, but compared with here, it was several times worse.

"Could this be Yin Yang Lake?"

Something moved in my heart.

Could this be Yin Yang Lake?

If not, how could there be such a weird thing, where yin and yang complement each other, and fire and cold alternate?

But... if so, how could it be so small?

With a diameter of two meters, it is estimated that only one person can enter, and it will be a bit crowded for two.

After all, cultivation is not about taking a bath. If you can’t believe it absolutely, you can’t practice peacefully and peacefully at such a close distance.

If Yin Yang Pond was only this big, Icefield Palace wouldn't be so famous.

He has cultivated countless disciples who practice yin and yang and are not weak in strength.

"Let's see what's going on..."

When he came to the front, his palm touched the water pool lightly.

call!

Books come to mind.

"The mother water of the source fire ice field, the people of the Ice Field Palace, use a special method to seal the earth veins to generate the source fire, and then fuse the special substance [ice field] to form it. It is very rare. Disadvantages: 1. Special personnel are needed to maintain it, otherwise, it will be easily destroyed..."

It is densely filled with content.

Read through what is recorded in the book.

"Sure enough, it's not Yin Yang Lake... I thought I found it!"

Shaked his head.

He thought he had found the Yin-Yang Pond directly, but now it seems that it is not that simple. The Yin-Yang Pond is the most important thing in the Icefield Palace. How could he find it so easily and enter it without anyone guarding it?

According to the description of the Library of Eradication of Tiandao, this thing called [Original Fire Icefield Mother Water] was created by people from the Icefield Palace who sealed the earth vein lava to generate source fire and cooperated with [Icefield].

As for what the ice field is, I originally thought it was a wilderness containing only ice and snow, but now it seems that it should be a special thing like the source of fire.

The name of a special ice attribute item.

"Previously, Hall Master Kang said that this place was originally the Flame Mountain, but later it became a land covered with ice and snow... The root cause should be here."

On the way here, Hall Master Kang introduced it in detail.

This place is a sea of ​​fire, unbearably hot and not even a blade of grass can grow.

The people of the Icefield Palace transformed it into a land covered with heavy snow.

If you guessed it correctly, it was caused by this small pool.

The water pool will be able to cover the earth veins that release heat and suppress it with ice sheets. The heat cannot be dissipated. According to the laws of nature, it is only a matter of time before such a high mountain is covered with cold snow.

This is just like a volcano that is so hot that no one can get close to it. The spewing magma is sealed by large means. As time goes by, the temperature will naturally drop.

"This thing can create illusions, which means it has an impact on the soul. What will happen if... my Shaman Soul enters it?"

An idea popped up.

Although this thing is not Yin Yang Pond, it is certain that it has an impact on the souls of cultivators. In this case... If you try it with Shaman Soul, will the effect be better?

"Try it!"

You can do whatever you want, there's nothing to hesitate about. It's all assessment anyway, and it doesn't count as being good at making opinions.

Sitting cross-legged on the spot, with a sudden movement of spirit, the Shaman Soul left the body and flew straight towards the pool in front of him.

Sizzle!

As soon as he entered it, cold air and hot air immediately poured into it, making his soul feel like it had fallen into a frying pan, suffering great torture.

However, while suffering, the soul also becomes clearer and stronger.

"good!"

Zhang Xuan nodded with satisfaction.

The Heavenly Soul Leading Technique he used has a strong soul that is not afraid of yin and yang and can freely swallow such powerful power. If it were other soul shaman masters, they would have been refined by the scorching heat of the water before they even came near.

Even... not only other soul shaman masters are like this, but even those who are strong in the spirit realm who practice true energy will easily be defeated and unable to bear the physical body when faced with such an exchange of cold and heat.

However, the invisible material of the soul is not like porcelain or steel, which naturally shrinks and expands when exposed to cold and heat, eventually causing it to break.

It can be said that this source of fire and ice is just right for him to cultivate the Shaman Soul, and no one else can do it.

"Absorb energy..."

Understanding this, he laughed, and the Shaman Soul suspended above the pool opened its mouth wide, and the alternating hot and cold energy below immediately poured into it like a hurricane.

The Heavenly Shaman Soul Skill was working hard, causing his cultivation level to constantly change.

Click!

The sound of breaking the wall sounded, and with a few breaths, the power of the soul reached the early stage of the third level from the previous peak of the second level of mortal transformation.

Moreover, with the operation of the technique, the yin and yang power below was still being drawn out frantically, causing his Shaman Soul to surge at a faster rate.

The early stage of the third level of mortal transformation!

The third mid-term stage!

The third late stage!

…

After absorbing the yin and yang power in the pond, his cultivation level increased rapidly, even twice as fast as absorbing spiritual energy.

"In this pool, yin and yang intersect, cold and heat conflict, and the Heavenly Dao Kung Fu complements each other, so progress is rapid..."

The speed of cultivation is fast, and Zhang Xuan also knows the reason.

The great road is one, which gives rise to two, two gives rise to three, and three gives rise to all things.

The Heavenly Dao Cultivation Technique is condensed from countless techniques and contains the principles of heaven and earth. The pool in front of you is like the change of yin and yang in the world, the fusion of yin and yang...

The combination of two doubled his cultivation speed.

However, this kind of doubling is not very effective for him.

After all, even if he absorbs spirit stones, he can easily break through a major level in an hour. Doubling it will only increase his cultivation level by a major level in half an hour.

It's not as exaggerated as imagined.

Of course, this is also related to his abnormal cultivation. If other people could improve their cultivation twice as fast, they would definitely wake up from their dreams laughing.

Boom!

After an unknown amount of time, the soul power shook violently and Zhang Xuan stopped.

The peak of the fourth level of mortal transformation... has arrived!

In less than an hour, his Shaman Soul strength suddenly increased from the second level of mortal transformation to the peak of the fourth level by two major levels!

Transformed into the fourth level of turbid and pure realm, the power increased from 800,000 cauldrons in the Yin and Yang realm to 1 million cauldrons.

At this small level, each time the cultivation level is advanced, the power of 200,000 cauldrons will be increased, which means that when reaching the fourth level peak, the power of the light shaman soul will be as much as 1.6 million! (1 million in the early stage of Zhuoqing realm, 1.2 million in the middle stage)

, 1.4 million in the later stage and 1.6 million in the peak.)
