Yi Xinji looked at the orange flame outside his body and showed a satisfied smile on his face.

He could feel that his Force temperature had more than doubled than half a year ago, but the exact degree was not certain. So he spoke out: "Augus, help me detect the temperature of the flame."

Augustus' figure emerged from the watch. A ray of light shot out from its eyes, searching on the flame, instantly calculated the result through the wavelength and blackbody radiation formula, and replied: "Average 1447 degrees Celsius."

"So high!"

Xin Ji was stunned. This was much higher than he expected. Before entering the fire pool to practice, his flame temperature was only five hundred degrees. After advancing from orange, he actually tripled in one breath. This cultivation effect is so good!

Augustus glanced at him and said, "This is just a start. You still have a lot of room for improvement in the orange flame stage. The next time the color temperature changes are three thousand degrees Celsius."

"Three thousand degrees, how long will it take?" Xin Ji exclaimed. He had searched the information in the federal government before, and the temperature of those powerful men with orange flames was only over a thousand degrees.

This is the horror of the nine-star martial arts. It is also an orange flame, but the temperature difference is like a natural barrier.

Augustus said: "The energy reserves of this high-energy fire pool are extremely high, and at least it can allow you to cultivate to yellow flames. Even the fourth stage of green flame is not impossible. Three thousand degrees are just a matter of time and can be reached in no time."

Xin Ji nodded to show that he understood.

His eyes swept through the cave. He practiced here for half a year, but the energy around him only slightly weakened a small part, perhaps less than half the total amount. Moreover, the fire pool radiated more energy day and night to replenish it. It would take many years to absorb all the energy.

"What a treasure land for cultivation!"

Xin Ji sighed in his heart that the cultivation conditions here are simply tailor-made for the thermal warriors. Even if he returns to the Federation himself in the future, he will not give up this high-energy fire pool.

Of course, the fact that I can strengthen the Force to orange so quickly is not entirely the function of the fire pool. The fire source crystals consumed alone are more than 400 yuan, and two yuan are used per day on average!

You should know that the energy of these fire source crystals can be as high as ordinary three or four yuan. In total, it is to invest about 5 billion federal coins every day for cultivation, which is astonishingly expensive.

It can also be said that your cultivation is all made up with money.

Xin Ji sank his mind into his body, and 108 Force meridians were listed, guiding them out of the nine star spirals, connecting all 1021 nodes together, forming a meridian network spread throughout the body. Each meridian is a complete circulation route, and the Force flows through one node after another, and finally returns to the star spiral to start a new cycle.

During the cycle, wherever the force passes, physical fitness will be slightly enhanced, and at the same time, vacuum energy is absorbed and converted into new force, which is integrated into gradually grow.

After the meridian network was completed, Xin Ji's cultivation speed increased again, and any part of his body was constantly absorbing vacuum energy and converting it into the force.

"This feeling..."

Xin Ji was extremely happy all over his body, his eyes condensed, and he punched him from the air.

While waving the arm, the four star spins involved in the right arm suddenly rotated, releasing a stream of force, which was transmitted into the arm along 17 meridians, just like a magnetic levitation train sprinting at a high speed on the track. Each node passing by is a booster. When it finally reaches the front end of the fist, the power of the force is magnified by more than ten times and instantly penetrates the body.

An orange light burst out from Xin Ji's fist and flashed away. Then the energy smoke in front of him appeared in a terrifying depression of a hundred meters, shaped like a fist mark, and finally hit the stone wall opposite the fire pool.

Boom...

The violent noise was deafening, and the cave was completely enclosed. The sound waves were shaking back and forth, and even Xin Ji could not stand it. He covered his ears and looked horrified.

It was not until more than ten seconds later that the sound gradually subsided.

Xin Ji put his hand down and saw a large pit with a diameter of about five meters appeared on the stone wall opposite. He was shocked. The stone wall of the cave had been roasted for tens of millions of years and turned into a hard and smooth glass-like shape, with a hardness of steel, and was more than 20 meters away from him, and he was punched such a big pit with one punch!

"I just punched casually, without using any punching skills, but the power is so terrible!"

Xin Ji felt incredible. Looking at his fist, he thought that even high-level generals and martial artists might not be able to handle this punch, let alone hitting ordinary people. If he had fist strength, such as the spiral force he used most now, and hitting it with one punch, he would probably not be able to bear it even the primary martial saint!

Only then did he realize that the difference between the Force and the Margin is so big!

"After the force was boosted by the meridians, its power increased by at least three times. In addition, my Force flame was advanced, and its power increased by more than ten times!"

After the shock, there was more excitement.

Xin Ji did not forget that the most important function of the meridian thread is to use the secret technique of the Force. He has learned only two secret techniques of the Force, namely the Void Blast Step and the Immortal Bright Flame. However, it is just a superficial use. It can only be said that it can be used, and it is far from being mastered.

The techniques of using the two secret techniques have long been remembered in the mind. The Void Blasting Step is the Body Technique, and the Immortal Bright Flame is used to protect the body.

Xin Ji looked at the cave. The space here was too small and it was occupied by the fire pool. The void explosion step could not be used, so he decided to try the Immortal Bright Flame first.

As soon as the mind moves, orange flames emerge from all over the body, forming a layer of flame protection.

"wrong."

Xin Ji frowned. This layer of protective flame was not much different from before. He simply covered a layer of the body surface. There was no skill, and his defense was far from reaching the maximum.

He recalled the scenes he had seen in the Singularity Star Core. The early and middle stages of Lord Yanhuang's life had relied on the powerful defense of the Immortal Blade to survive many times.

Lord Yanhuang's immortal bright flame is completely different from his own. It is in a very stable state and does not have the thundering feeling of flames at all. It is like a crystal-like armor. Without special excitation, the surface is only at room temperature and never leaves the body. Outsiders do not know the inside story and it is easy to mistakenly think that this is a close-fitting armor made of solid materials with extremely high hardness.

"This is the true form of the Immortal Blade!"

Xin Ji realized in his heart that the immortal flame is not actually a large piece, but is assembled from hundreds of small parts, and the material that makes up the parts is the force of the highly compressed force.

Of course, I am only at the moment in the cultivation of a military general. The force is gaseous, and it is too difficult to compress it into a solid state and it cannot be maintained.

However, it is still possible to compress the Force and increase the density by increasing the density.

Xin Ji did not rush to start, and moved two steps forward to the center of the fire pool. The temperature he felt around him soared, but it was still tolerated. In the past six months, he moved a little to the center of the fire pool every once in a while, and now he is less than five meters away from the center.

There are still many fire source crystals and plenty of time. Xin Ji decided to use the fire pool to gather the latitude of the power and wisp of the power and rush to the realm of a high-level general!

After all the Jingwei Network is formed, and then transform the Force to fill them, you will be the peak general.

The meridians connect the star spines and nodes, while the latitude lines are different, and have no direct relationship with the star spines. They only exist between nodes. If the entire meridian network is a big tree, then the meridian is the trunk and the latiligo is the branches and leaves, which are used to fill in details. The circulation directions of the two intersect, or even completely opposite, eventually forming a network similar to the meridian coordinate system.

The number of latitude lines is much larger than the meridian, and the overall length is more than several times the meridian. The number of latitude lines in "Nine Yang Nine Dimension Fusion Magical Art" is even more outrageous, with a total of 521 pieces, divided into 10,099 sections!

When Xin Ji saw so many latitudes, he was frightened and his scalp was numb. He hadn't come back to his senses for a long time.

You should know that the four-star "Seven Colored Star Flame" has only seventy-two latitudes, which is a terrible number that has deterred countless people in the Federation, and the 521 latitudes are completely unsuccessful in less than a few hundred years.

Now that I have really reached this point of cultivation, Xin Ji didn't think too much. He took a deep breath, took out a new fire source crystal and held it in his hand, and fifteen thoughts appeared in his mind, and began to condense the latitude step by step.

With the complete meridians and the advancement of the Force's orange flame, the cultivation speed has been increased. Now, fifteen thoughts can be used to cultivate the Force at the same time. Even if there are many latitudes, you will not be afraid.

While practicing, the Force's mind and power advance together, while pondering the techniques of using the Immortal Blade.

"The immortal flames should be used in combination with meridians and nodes, make full use of their condensation effect on the Force, and output the Force from various parts of the body. Each star spin and node covers some areas, just like playing puzzles, connecting with each other, and supporting each other, and finally forming defensive armor."

Xin Ji started with his forearm and tried it repeatedly for more than an hour before he mastered the technique of compressing the force. He released a compressed force and turned it into a small piece of armor and stuck it on the skin.

"Done."

This piece of armor does not look like a flame at all, the temperature is not high, and it does not emit light outward, like a dim jade sheet, with a thickness of only five millimeters!

Xin Ji pressed it with his finger. When he was under pressure, the armor plate suddenly became hot and lit up, and the body continued to provide force to resist the pressure. As long as the force is inexhaustible or the pressure does not exceed the tolerance limit, it will not collapse.

“What a strong toughness and hardness!”

Xin Ji knew that his direction of exploration was right, so he continued to work hard to cover the Immortal Blade. A day later, when half of his arm covered a layer of armor, he suddenly felt shocked and the first latitude was completed!

"So quickly condensed one..." Even Xin Ji was a little surprised. He did not expect that after the Force advanced to the orange flame, it would be so easy to condense the latitude line. As long as it condensed, it would not collapse and be very stable.

At this speed, he can complete all the latitude lines in just one and a half years and be promoted to the level of a high-level general!

Just two years ago, Xin Ji went through a practice process of ordinary generals for a hundred years or even longer, and he practiced the "Nine Yang Nine Dimensional Fusion Magical Art", which was many times more difficult than ordinary skills. Such a terrible cultivation speed is invincible in the entire Milky Way, and even this super galaxy cluster is unrivaled!

Xin Ji smiled faintly. No one would think that he would practice too quickly. Not to mention two years, he would remain calm even for two days.

In this completely closed cave, Xin Ji was isolated from the world, ignored the direction of the fighting pressure of the mineral veins outside, and even telepathy contracted, covering only the fire pool. Occasionally, a few vibrations came from outside the volcanic stone wall, and he ignored them.

Time passes by quickly in practice.

Every day, Xin Ji could clearly feel that he was getting stronger. Yesterday was stronger than the day before yesterday, and today was stronger than yesterday. One latitude after another condensed, the temperature of the force flame steadily increased, the color became darker and darker, and the radiated light waves gradually moved backwards in the spectrum.

The growing pleasure of cultivation is incompetent, and Xin Ji is immersed in it, and it is not enough to be understood by outsiders.

Eight months later, Xin Ji had condensed a small half of the latitude line, and the immortal bright flame was finally completed, covering the whole body, like a piece of armor made of crystals, pressing against the skin a thin layer, with smooth lines, and the heat power flowing under the armor, which was extremely tough and did not affect his own movements at all.

"I finally stopped running naked."

Xin Ji smiled bitterly. Since he entered the Fire Pool to practice, because the clothes in the sub-space are not heat-resistant enough, they are burned to ashes as soon as they are taken out, so he has been running naked for more than a year.

He was about to test the defense of the Immortal Blade when suddenly, telepathically sensed a trace of abnormality.

The surface of the high-energy fire pool is calm like a mirror, unchanging forever, but at this moment, there are several waves, spreading out quickly. After a few rounds of rippling, the center position rises upward, as if something is about to come out from below.

This change was extraordinary and immediately scared Xin Ji.

You should know that the bottom of the fire pool is unfathomable and the temperature is even more terrible. He had telepathically explored it when he first came in, but he couldn't find it at all and didn't know where it leads.

"What?"

Xin Ji was quite caught off guard. As soon as his telepathy entered, a huge head floated out of the fire pool.

"Fire Crystal Dragon! No..."

This is Xin Ji's first impression when he saw the other person. It is seventy-seventh-point similar to the Fire Crystal Dragon outside, but it is much smaller in size and less than half a meter in diameter. There is a long beard under the jaw of the dragon head, which is a bit elegant in its hideousness. The scales are light blue and have silver-gray pupils. At this moment, he is also staring at Xin Ji, his eyes full of surprise, and obviously has extremely high wisdom.

"What kind of creature is this? Four-legged snake?" At this time, Xin Ji had detected the part of the creature hiding in the fire pool.

Its body is much smaller than the Fire Crystal Dragon, less than ten meters long, and its body is slender like a python, but it has dorsal fins on its back and four sharp claws under its abdomen, two in front and two in the back. The scales and body are translucent, as if they are composed of light blue diamonds. You can directly see the spine in its body, making it look fierce and beautiful.

Xin Ji was alert in his heart that this creature was not afraid of the high temperature of the fire pool and could swim in the potential magma. Moreover, extremely huge energy fluctuations came from its body, equivalent to a level seven to eight flame beast!

He quickly retreated, and at the same time, the electromagnetic force entangled the flame beast he had never seen before. He was about to punch out, but his eyes suddenly disappeared and it disappeared!

"Uh...where have you gone?" Xin Ji was really scared. A living fire beast disappeared out of thin air, and even telepathy could not find its location.
Chapter completed!
