The God of War.

Cleansing the essence and marrow is the most painful thing. According to the requirements of the Heaven-Swallowing Divine Art, each time the realm is upgraded, the personal physical strength must be increased to the limit of the previous level. Only in this way can one enter the next level without leaving any defects in cultivation. Don't underestimate these small defects that seem to be no big problem. If accumulated over the years, they will continue to accumulate in the body and will completely erupt when a certain realm is broken through. The injured may have their muscles and fats destroyed, or they may go astray and become possessed. There is also a most dangerous possibility, that is, the body cannot support the explosive growth of spiritual energy and finally dies.

Therefore, since Lin Fei started practicing the Heaven-Swallowing Divine Cauldron, every time he reached a higher level, he had to undergo a thorough marrow cleansing and essence removal, in order to thoroughly cleanse and temper his body.

The technique that Lin Fei practices is different from that of ordinary people. The techniques that ordinary people practice are based on the limits of each realm and are adapted to that realm. Therefore, there is no mismatch between the technique and the realm, and the physical strength requirements are not too strict. Lin Fei started practicing the god-level technique, which has extremely strict requirements on the body. It requires that every step must be taken into consideration, and the physical strength of the practitioner must be many times higher than that of ordinary people.

This is also the reason why Lin Fei must be careful at every step, and the reason why his physical strength is a hundred times or even higher than others.

Killing an enemy above their level, although it is just four simple words, the hard work and difficulty involved is not something that ordinary people can understand.

The world of cultivation can be said to be full of crisis at every step, so there is no rest in this world. In this world that feels crisis and danger all the time, for any two people, perhaps, you and him are friends today, but tomorrow, you may become mortal enemies. If your cultivation is lower than his or your ability is not as good as his, then, I'm sorry, you may become his dead soul.

After entering this world, Lin Fei has always felt crisis and danger. He has never known what rest is. From that time on, cultivation and improvement became an important task for him every day.

Lin Fei took out a Yuan Ju Dan suitable for the Foundation Establishment Realm that he got from the Heavenly Palace and swallowed it. He felt a pure spiritual energy entering the Divine Cauldron, which was then refined and compressed again by the Divine Cauldron and turned into a golden multi-spiritual liquid, which was injected into Lin Fei's Dantian.

As the saying goes, one flower, one world; one leaf, one bodhi. Everything has its own orbit and method of operation. This is why the world is so complex and multifaceted, just like Lin Fei's Dantian. Every time he looks inward, Lin Fei always feels that his Dantian is undergoing a change that he cannot know.

Sometimes, Lin Fei would see a black object appear in the middle of the ocean of spiritual liquid. Especially when the spiritual liquid decreased, this object would appear particularly dazzling, like a small island in the vast ocean.

There were several times when Lin Fei wanted to extend his spiritual sense in to find out what this thing was. Unfortunately, there was nothing he could do because his own spiritual sense was blocked outside his own dantian.

He didn't know what this divine cauldron wanted to do. But there was no other way. Now that the divine cauldron occupied the entire Dantian, Lin Fei only had the power to use the spiritual liquid.

As the refining of the elixir was completed, the spiritual liquid in Lin Fei's dantian increased a lot. Now it was midnight and the surroundings had become completely quiet. Feeling that there was no danger, Lin Fei decided to start tempering his body.

"Get up!" Lin Fei shouted, and the spiritual liquid in Dantian immediately rushed into his tendons and veins, and then entered the bones, muscles and every tiny tissue of the body along the tendons and veins. The effect of spiritual liquid is much greater than that of spiritual energy, and it tempers the body more directly than spiritual energy. Therefore, the pain that Lin Fei has to endure is also more direct.

Although the tempering during the last breakthrough was thorough, it was the last time to improve the physical strength of the sixth level of foundation building. This time is the first tempering after entering the seventh level. According to the requirements of the Heaven-Swallowing Divine Art, for each level upgrade, one must temper and cleanse oneself at least three to four times, and highly maintain the highest strength and purity of one's own body to make one's body defense as strong as possible. Only in this way can one ensure that when a huge amount of spiritual energy is needed, it can reach the strongest and fastest without damaging one's tendons.

The Heaven-Swallowing Divine Art was running quickly, and Ling Fei felt that his bones were constantly being shattered and then reorganized. During the process of shattering and reorganizing, all kinds of impurities originally contained in the bones and muscles were wrapped in the spiritual fluid and sent out of the skin. At the same time, the runes flashing on Lin Fei's bones and tendons became more complex and mysterious. At the same time, Lin Fei felt that his bones and tendons were constantly strengthening.

In less than an hour, Lin Fei's originally white skin was covered with a layer of sticky oily substance. This substance smelled fishy and bad, but compared with the pain in his body, it was nothing.

Even so, Lin Fei had to endure it, because at this time, the tempering had entered a critical moment, and any carelessness could cause irreversible damage to his body and tendons or even cause him to go crazy.

This is also the important reason why all cultivators need someone to protect them when they are tempering and breaking through.

Three hours later, the sky had begun to turn white, and Lin Fei's tempering had come to an end.

After his body fully recovered, the spiritual fluid in his dantian was reduced by one tenth. After refining a Kunyuan Pill, Lin Fei felt that the consumed spiritual fluid was replenished all at once.

After that, Lin Fei absorbed another twenty pieces of low-grade spirit stones. Lin Fei felt his body was stronger than ever before. He opened his eyes and felt that the outside world was much clearer. He found that he could only see things within a hundred meters. Now, he could see at least within a hundred and fifty meters. Within a hundred meters, even a mosquito could not escape Lin Fei's eyes. This was before he practiced the skills related to spiritual consciousness. Moreover, he found that his spiritual consciousness had also been strengthened a lot. If it was at night and there was no light, he could feel things within at least ten meters.

Now, what Lin Fei wanted to know most was how powerful his strongest move could be. If combined with the golden spirit liquid, the Netherworld Sword and the Blade of Destruction, thinking of this, the corner of Lin Fei's beak tilted upwards.

However, the most important thing now is how to clean these things from his body. Looking at the black mud on his body, Lin Fei suddenly felt like vomiting.

Walking out of the cave, everything outside became particularly beautiful in Lin Fei's eyes.

Let’s go, first find a place with water and wash ourselves, then go down into the deep pit and look for herbs.

Haha, just wait, little wolf boys!

Lin Fei ran down the mountain in one leap.

Based on the experience of survival in the wild that Lin Fei learned in college, he soon found a small river. The river originated from Yingzui Mountain and rushed all the way down. It flowed to an unknown place at the foot of Yingzui Mountain.

The river water is clear and transparent, with various unknown aquatic plants and many small fish playing in the water. If Lin Fei encounters such a river in college, he will definitely not let it go. However, Lin Fei is not in the mood to appreciate these beautiful scenery now. He still has an important task to complete, and his body must become stronger in the shortest time to adapt to the laws of this world.

Lin Fei found a place with deeper water and jumped in. Now he was not afraid of the water or any monster attacking him. He washed off the dirt on his body, then took out a new set of clothes from the ring and put them on. A peerlessly handsome man appeared in the stream of Yingzui Mountain.

This young man, who is just thirteen years old, has a tall and straight figure and handsome looks. He has an elegant and graceful demeanor, with a faint smile on the corners of his lips. He looks elegant and refined in a white robe. On his handsome face with clear lines, his eyebrows slant into his temples, his eyes are bright and lively, and there is an air of bookishness between his brows that is hard to conceal. He looks elegant, gentle and suave.

Even if you are a peerless beauty with unprecedented pride and extraordinary beauty, you will fall into the arms of such a handsome man when you see him.

Leaving the stream, Lin Fei quickly appeared at the edge of the deep pit. It was morning at this time, and strong air convection brought up the cold and humid air below, forming a layer of white fog above the deep pit. Looking through the fog, looking at the darkness below where even light could not escape, and the cool wind rising from below, Lin Fei no longer felt as relaxed as before.

Without hesitation, Lin Fei began to climb into the deep pit.

Slowly walking down the rock wall, the most noticeable thing is the sudden drop in temperature. The fierce sunlight that we felt just above has become like a docile girl here. However, you can't feel the girl's kindness. There is only a frightening coldness here, as if this girl is not a lady, but a cold-faced witch.

As the depth increases, the vegetation changes in a stepped manner, and at the same time, the monsters that appear begin to become smaller.

After an hour and a half, Lin Fei slowly arrived at a place of one hundred feet. There were no tall trees here. Some low herbs and some bushes that liked shade grew here. Except for some small monsters such as red-blood ants, black spirit tree snakes and other lower-level monsters, no larger animals could be seen here. Moreover, the concentration of spiritual energy here was constantly decreasing. When it reached a depth of one hundred and twenty feet, Lin Fei could no longer feel the concentration of spiritual energy.

Lin Fei had not expected the difficulty of this task to be so great, and finally understood the important reason why no one had taken up this task for so long. As a martial artist seeking the truth, spiritual energy is as important as the air for survival.

No one would want to set foot in a place without spiritual energy.

This world is a world where spiritual energy is the fighting force. If there is no spiritual energy to supplement it, you can imagine how terrible it is. It is like a fire. Even if you have a spark to ignite it, but if there is no firewood as the root of the fire, this fire is also a fire without a source and will soon go out.

There was no way out. Having come here, Lin Fei had to continue going deeper. Lin Fei never had the habit of retreating.

Fortunately, Lin Fei's spiritual energy reserves are countless times higher than those of ordinary people. However, at this time, because climbing the rock wall also requires the use of spiritual energy, Lin Fei still feels that his spiritual energy is slowly decreasing.

The rock wall was covered with moss and was very damp, leaving no place for hands and feet to take root. Sometimes, Lin Fei had to rely on the tiny protrusions of the rock wall and then use his spiritual energy to stick to it to climb down.

Lin Fei didn't even dare to think about jumping down, because he was too unfamiliar with the environment here. Too loud a noise might alert the unknown creatures hiding here, and then there would be no way out.

Coming to a wider platform, Lin Fei estimated that the depth here was at least 170 feet. However, apart from some moss, there were no other plants living here.

Looking at the scene around him, Lin Fei now began to doubt the authenticity of this mission.

According to the description of the task, if the Iron Sword Golden Heart Grass lives two hundred feet below the pit, then there is still another thirty feet below. The temperature here is already very low. Lin Fei can feel the cold here with his body's defense strength and spiritual energy reserves. What's more, there is not a trace of spiritual energy below. As a spiritual grass, it also relies on spiritual energy to grow. Under such extreme conditions, if it continues to live there, will there be any plants that can adapt to the living conditions there?

Lin Fei almost dared not imagine it. Lin Fei wondered if this was a task that someone had deliberately set that was impossible to complete.

However, if you don't go down to that location, how can you know the authenticity of this mission? Thinking of this, Lin Fei could only smile bitterly.

"It's really a dilemma!"

After resting for a while, refining a few spirit stones, and replenishing the spiritual energy lost along the way, Lin Fei continued to go down. Although it was not long after noon, the sunlight could no longer reach here. It was also because Lin Fei's eyes were extraordinary. With the faint light, he could see things within a range of about twenty feet.

It took Lin Fei twice as long to go down twenty feet as it did to go up the top ten feet. According to the description, the last ten feet would lead him into the territory of the Blood Jade Wolf Pearl.

Standing on the edge of the rock, Lin Fei cast his gaze downwards. What met Lin Xi's eyes was full of solemnity. Although the Blood Jade Wolf Beads were small in size, they had extremely fast speed and attack power on the cliffs. In addition, their astonishing number and their bodies were full of poison. In such an environment, even if you had the most powerful cultivation, they could still slowly eat you up. Even your bones could be corroded, dissolved, and finally eaten by their poison.

Each of the following steps becomes cautious. It can be said that this is a gamble with one's own life, luck, speed, in a general sense, a gamble with one's life.

Nine zhang.

Eight feet.

……

When he reached the last three meters, Lin Fei saw a cave. This cave was a bit special in that the areas around the entrance were smoother than other places, and there was not even a trace of moss.

Lin Fei guessed that this cave should be the lair of the Blood Jade Wolf Spider. Only places where a large number of animals frequently come and go would have such smooth traces and no plants would be left behind.

And below the cave, about two meters away, there was a vermilion-gold grass growing in a crevice on the cliff, and there were no other animals or plants around the grass.

This grass is like a bead of light in the dark night, exuding a breathtaking charm.

Iron Sword Golden Heart Grass! It really grows in a place like this!

Lin Fei couldn't help but sigh at the wonders of nature. There are so many good places for it to grow, but it has to grow in a place like this without soil and spiritual energy.
