Eight hundred miles south of Xuanming City, there is a valley.
The land in the valley is dark red, not the color of blood deposits, but the color rendered by high temperatures.
The air is filled with a pungent smell, it's the smell of sulfur, and it's also filled with fiery heat. Ordinary people can't get close to this place, and they will either die of poisoning or dehydration.
Practitioners in the Foundation Establishment realm also dare not approach it, as they will also die.
Only those who have reached the extraordinary realm in cultivation can approach this place.
This is the location of the Earth Fire Cave.
And the Earth Fire Cave happens to be controlled by the Ancient Xuanhui.
Guxuanhui's industries are spread throughout the Xuanming Realm, and there are naturally alchemists, weapon refiners, etc. inside. This Earth Fire Cave is a place where Guxuanhui refines weapons.
"Mr. Chen, there is the Earth Fire Cave ahead." A deacon from Guxuanhui led the way and pointed at a flashing red cave entrance directly in front of him. Hot and high temperatures were spreading out from the cave entrance, like an open hole.
The mouth of the fire beast is the same, as if it wants to burn everything.
The deacon of the Ancient Xuanhui didn't know why Chen Zong came here.
After all, the Earth Fire Cave is the place where the ancient Xuanhui's weapon refiners refine their weapons. The temperature is extremely hot and full of fire poison. Even those weapon refiners who have entered the holy realm are not willing to stay there for a long time.
After staying in the Earth Fire Cave for several months, you must leave and recuperate for a month or two to allow the effects of the fire poison to disappear before you can enter again.
A semi-saint can only stay there for a few days at most.
I don't understand, I don't understand what the other party is trying to do.
But Gu Xuanhui also intends to make friends with the other party. After all, he is a talented person with extremely high potential. Therefore, he must obey the order.
On the contrary, after taking the opponent into the underground fire cave, nothing will happen to him.
Chen Zong followed the deacon of the Ancient Xuanhui into the underground fire cave, and immediately felt that the temperature was rising, and the red light became more and more dazzling, as if there was a fierce flame burning in front of his eyes, as if to
Burn yourself to ashes.
However, this level of high temperature is nothing to me, because he has the purple cloud and black star flames to protect his body.
Although Ziyun Black Star Flame does not have much effect on increasing his current strength, it is still good at resisting high temperatures.
Moreover, Chen Zong could also feel that the fire poison that permeated the Earth Fire Cave entered his body and was purified by the power of the Ziyun Black Star Flame, unable to cause any damage to his body.
In other words, Chen Zong can stay here as long as he wants.
"Mr. Chen, you must be careful not to enter the deepest part of the Earth Fire Cave. The temperature in that Earth Fire Lake is very scary and very dangerous." The deacon said solemnly.
"Okay." Chen Zong nodded.
"Then I'll take my leave. I'll pick you up in a few days." After the deacon finished speaking, he turned and left. He had other things to do and couldn't stay here to accompany Chen Zong.
Chen Zong looked around. This is a natural cave, a cave where earth fire gathers. There are many cone-shaped stones inside, either protruding from the ground or hanging down from above. The red light is blazing and looks like a statue.
The inside of the mouth of the ancient fire beast is filled with intertwined canine teeth, which is extremely dense.
The weapon refiners of the Ancient Xuanhui naturally have their place, and Chen Zong will not disturb them, nor does he want to disturb them.
After looking at it, Chen Zong immediately took steps towards the deepest part of the Dihuo Cave.
The purpose of entering the Earth Fire Cave was to enter the deepest part and use the power of the Earth Fire to practice the Three Tribulations sharp edge.
Three tribulations sharpen the edge!
This secret technique was created by a powerful swordsman in the Great Sage Realm in his later stage, in order to hone his supreme sword intention.
The Three Tribulations Sharpening is divided into three tribulations, and the condition for cultivation is half-step sword intention.
If you have already mastered the Taoist intention of the sword and then practice it, it will be a bit slow. It is effective, but it cannot be used to the extreme. Moreover, the higher the level of the Taoist intention, the worse the training effect.
Basically, after the third transformation of Dao Yi, it is completely ineffective.
The half-step sword intention level is the most suitable level for practicing Three Tribulations Sharpening. At least, you have to practice it for the first tribulation. After the two tribulations, you can wait until the half-step sword intention breaks through to the real sword intention before practicing.
It is also because half-step sword intent cannot withstand the tempering of the second calamity, let alone the stronger third calamity.
Three tribulations sharpen the edge!
The three calamities of this secret method are earth fire, sky wind, and void thunder.
Earth fire is the easiest to find, followed by sky wind, and void thunder is the hardest to find.
As Chen Zong continued to go deeper, he could feel the temperature getting higher and higher. Gradually, the power of Ziyun Black Star Flame became irresistible.
However, Chen Zong himself has a strong body and a high resistance to heat and high temperatures, so he can still withstand it.
Go deeper, deeper, deeper and deeper.
The red light was extremely dazzling, shining in all directions, making it difficult for Chen Zong to look directly, as if his eyes were being burned on a fire.
Hot, hot, hot!
The heat that invades from the outside world is like the heat that burns all living things on the earth, the heat that seems to turn itself into ashes.
Carrying the high temperature, Chen Zong walked forward and saw a small lake.
The small lake was only about fifty meters in diameter. It was red and extremely dazzling, making it difficult for Chen Zong to open his eyes.
Earthfire Lake!
It was a lake that was finally formed by countless earth fires after countless years of accumulation and precipitation. The liquid that looked red and shimmering inside was actually not a real liquid, but was condensed to an extremely high form. It looked like a viscous liquid.
feeling.
Like magma.
On the surface of the Earth Fire Lake, there is still a layer of faint, almost transparent flames burning. Chen Zong can feel the terrifying power of that layer of almost void flames, which is even more terrifying than his own Purple Cloud Black Star Flame.
The Ancient Fire Refining Technique was running, and the Ziyun Black Star Flame suddenly moved every part of the body in a mysterious trajectory, which greatly resisted the terrifying high temperature caused by the burning of the Earth Fire Lake, allowing Chen Zong to stay here longer.
time.
Then, he began to practice the secret method of sharpening the edge for three tribulations.
Fortunately, Chen Zong was able to divide his mind into two tasks, otherwise only one of the Xuangu Fire Refining Technique or the Three Tribulations Sharpening Secret Technique could be used.
Half-step sword intention is a kind of void power, which is different from spiritual power and half holy power.
Chen Zong ran the first calamity of the Three Tribulations Sharpening the Front. Immediately, a trace of earth fire energy was attracted and quickly entered Chen Zong's sea of consciousness, which was where the half-step sword intention was.
At the same time, the half-step sword intention also condensed out of the sea of consciousness.
The energy of the earth fire was so pure and extremely hot that as soon as it entered the sea of consciousness, Chen Zong felt as if his sea of consciousness had been burned to ashes, and the pain was excruciating.
Chen Zong had to endure it.
The energy of earthly fire spread rapidly, wrapping the condensed half-step sword intent and burning it continuously.
The severe pain became more intense and increased several times, making Chen Zong feel like fainting, but he had to hold on and stay awake. Otherwise, not only would the tempering effect not be achieved, but half of the sword intention would be burned.
He will no longer be able to understand the meaning of the sword, and even his soul will be seriously injured.
The price is indeed astonishing, but if one can master the secret technique of sharpening the edge for three tribulations, one can create the supreme sword intent, and the rewards will be astonishing.
Chen Zong was guessing whether the so-called supreme refers to Taoism that transcends higher levels.
If so, that's really amazing.
No matter what, a secret technique created by a powerful swordsman in the Great Sage Realm at a late stage is still extraordinary.
Wisp after wisp of earthly fire energy was drawn, gradually drifting into the sea of consciousness, wrapping half a step of sword intention, and burning continuously, as if calcining the sword embryo.
The high temperature caused Chen Zong to endure great pain. The pain directly impacted his soul, and it felt like his soul was being roasted on a raging fire.
Bear it, control it, and keep tempering.
This is a fire disaster.
Disaster!
This is a catastrophe. If you survive the catastrophe, you can be reborn.
The half-step sword intention seemed to melt under the burning energy of earth fire. Chen Zong had to control it and keep gathering it. This was very difficult and very labor-intensive.
Without a strong enough mental will, there is simply no way to support it.
In other words, even if most cultivators obtain secret techniques like Sanjie Lifeng, they will not be able to practice successfully.
Gradually, Chen Zong endured it and adapted to the high temperature.
This is just the beginning, absorbing more earth fire energy into the sea of consciousness and tempering the half-step sword intent. Under this tempering, the half-step sword intent seems to become more solid.
Refining!
Refining!
Refining!
As more and more earth fire energy enters the sea of consciousness, it continues to condense, and gradually turns into a flame that burns. The flame also continues to absorb the external earth fire energy, becoming more and more powerful.
The first calamity of the three calamities sharpening the sword, the earth fire calamity, is to use earth fire to temper the half-step sword intent.
But the cultivator cannot release the half-step sword intention and put it into the earth fire for a long time, so he can only do the opposite and let the earth fire burn in his sea of consciousness.
How to set fire to the earth within the sea of consciousness?
The most powerful sword cultivator in the Great Saint Realm suddenly had a whim, so he absorbed the energy of earth fire one by one, starting from the smallest, accumulating improvement bit by bit, allowing himself to endure and adapt until the end.
, when the energy of earth fire is sufficient, it can be condensed into a ball of flame, and then continuously absorbed to become a real earth fire.
In this way, it can be regarded as truly using earth fire to temper the half-step sword intention.
It took a full half day for Chen Zongfang to absorb enough earth fire energy to form earth fire in the sea of consciousness.
As soon as the earth fire appeared, Chen Zong felt as if his consciousness was about to be burned, and even his soul was trembling under the high temperature.
It is extremely terrifying. If you are not careful, the sea of consciousness will be destroyed by this terrifying earth fire, and even your soul will be burned to ashes.
Exquisite control!
The Three Tribulation Sharpening Edge is extremely sophisticated. As long as Chen Zong keeps operating and his spirit and will can support it, it can withstand the burning of the earth fire, thus continuously tempering the half-step sword intent.
It's like the process of casting an iron block into a sword embryo.
Time passed slowly, and an earth fire kept burning in the sea of consciousness, constantly calcining the half-step sword intent. As the earth fire burned, the half-step sword intent gradually became more solid.
This is the depth of the Earth Fire Cave. In most cases, no one will come, but occasionally strong people will appear.
At this moment, an old man wearing a fiery red robe flew over. When he saw Chen Zong, he was shocked.
Because he felt Chen Zong's aura fluctuations.
High-level semi-saint level!
When did high-level semi-saints come here to practice? Aren’t they looking for death?
The old man's hair was fiery red, and under the firelight of the Earth Fire Lake, it looked like a burning flame. He stared at Chen Zong, as if he wanted to see through Chen Zong's reality.
