From the breakthrough of qi refining to the foundation building, it is the process of the cultivator to wash the marrow and cut the veins to reshape the physical body, because Xuan Fei's body has experienced a breakthrough, so it needs the assistance of external forces. This is fundamentally different from those cultivators who have poor spiritual roots and are unable to break through the realm when they encounter bottlenecks.

It's like two same containers, a small bowl and a large vat, the small bowl is filled with water and then added a little more will overflow and can no longer rise the water level, the same amount of water in the large tank may not be as high as the water level of the small bowl, but through a more efficient way or tools to continue to fill the large tank with a large amount of water, the water level can rise to another height that the small bowl can never reach.

Tsukidan is similar to this efficient tool, of course, it doesn't mean that without Tsukidan, Xuanfei can't break through, it's just that the breakthrough time will be longer, and the accumulation required will be more. Although the water level of the large tank does not rise significantly, as long as water is added to it, the water level will still rise a little bit, unless the tank is leaking.

Xuan Fei's strong body, which has experienced a marrow washing and vein, is much stronger than an ordinary tank, so how could it be leaking?

After leaving the Hundred Treasure Pavilion, he gave the box to Sun Zhutou as promised, and then embarked on the road back to the Sword Pavilion alone. Because the delay in Yining Town exceeded the budget, the official road was abandoned and a closer road was chosen, which had to pass through a branch of the Xishan Spiritual Vein.

The Xishan spiritual vein is located in the middle of the Dongzhou Continent and the Vientiane Domain Continent, belonging to the Dongzhou Continent, rich in spirit stones, for many years, whether it is the Dongzhou Continent or the Vientiane Domain, many countries have been eyeing here, fighting for the right to mine the spiritual vein, and then was turned the tide by the Dragon Dynasty and controlled in the hands.

There are a total of seventy sub-veins in the spirit veins of the West Mountain, and each of them is surrounded by the strongest troops in the Dongzhou Continent, the seventy-two battalions of the West Mountain. Although it is a border defense army, it is full of strong people, comparable to a super sect in the cultivation world, and is as famous as Xuanxu Cave and Yanxia Pavilion, and is one of the three major super forces recognized by the Dongzhou Continent.

In Xuan Fei's memory, he had an impression of the forces of the 72nd Battalion of Xishan, so the path he chose was naturally far away from the patrol range of the defenders of the 72nd Battalion of Xishan. He didn't want to be arrested as a mine thief or a military spy for no reason. The route he had chosen was just a small branch of the most remote part of the Spirit Vein in the West Mountain. Usually, there are many strong cultivators who pass through this road, but there is not a single mortal.

It's not that mortals don't know that there are no people from the seventy-two camps of Xishan patrolling here, but because of the gathering of spiritual veins and spirit stones in Xishan, the spiritual energy is full, and many powerful beasts have been bred.

On the way to Xuanfei, he accidentally found a hidden cave, went into the cave to explore, and found no traces of other people and strange beasts, which was very suitable for meditation and cultivation, so he planned to take Zhuji Dan in the cave and start to break through.

He sat down cross-legged, took out the Tsukidan wrapped in brocade, and put it in his mouth, only to feel a bitter meaning, and he entered his mouth and went straight to his internal organs through the delay.

The pill is in the mouth, slowly melting and shrinking, until it disappears completely, the bitterness is more intense, the blood in the body begins to boil, the body gradually grows warmth, and then slowly becomes scorching, and the skin continues to ooze beads of sweat the size of beans, and then turned into steam by the burning body.

The vitality in the sea of dantian qi was boiling, like boiling hot water, frantically pouring into the eight veins of the Qi Jing, constantly washing and cleaning, and the skeletal muscles were also continuously broken and reborn in the blazing heat, and so on.

Xuan Fei endured the heart-rending pain and resolutely maintained a clear consciousness, he knew very well that once his consciousness collapsed, not only would everything be wasted, but he was also very willing to be able to break through the realm again for the rest of his life. This is like the last crisis before the company goes public, no matter how hard and difficult it is, it must survive, otherwise not only all the previous efforts will be in vain, but also may be bankrupt and burdened, and there will never be a day to turn over.

I don't know how long it took, the bitterness of the pill gradually faded, the faint sweetness swirled in the mouth, the temperature of the body slowly decreased, the dantian qi returned to peace, and the meridians of the whole body were smooth and refreshing, which reminded Xuan Fei of the feeling after steaming in the sauna in his previous life, and this feeling was a hundred times more refreshing than that after steaming in the sauna.

"Did I make a breakthrough?"

After this torment of wanting to die, he couldn't believe it, he had really succeeded in breaking through, he didn't have 100% hope for this expired pill, "I really didn't expect that the pill that has been stored for nearly a hundred years can still have such a strong medicinal effect!"

What he didn't know was that this Tsukidan was a top-grade Tsukidan that was unique in a thousand miles, although it was true that it had lost most of its medicinal effects in a long hundred years, it was more than enough to help a cultivator with extraordinary talent like him break through, but after the breakthrough, there was not much left of the dantian qi, and it would take time to recover.

That is, when he was the weakest, a crisis appeared, the world is always full of coincidences, if this crisis came one step earlier, Xuan Fei would definitely die, and he would meet Xuan Fei a moment later, but the pieces were met when Xuan Fei had just broken through the weakest and did not have time to leave in a hurry.

The entrance to the cave was blocked by dense weeds and shrubs, and Xuan Fei couldn't see the situation outside, but only heard the sound of rustling, if it was limited to that, it might be the sound of ordinary beasts and birds shuttling between the grass and trees. However, even clearer than this voice was a strong fluctuation of vitality.

This vitality fluctuation has no introverted meaning, turbulent and crazy, full of beastliness, Xuan Fei immediately searched out two words from the memory of the body that made him have to panic two words "alien beast", he knew that there were often strange beasts near the spiritual veins of this West Mountain, but he didn't expect that this strange beast happened to appear when he had just broken through the emptiness of the qi sea.

After breaking through the foundation, he not only made a qualitative leap in his body, but also initially groped for the door of his divine sense.

The so-called divine consciousness is a kind of perception ability that is detached from the unconscious, he can capture all kinds of information about the target more accurately and intuitively, such as the appearance of the target, the appearance of the target, the appearance of the expression, the strength and weakness of the cultivation, the emotional thinking, and the extreme can also control others to occupy the body.

Of course, this is all a later story, with Xuan Fei's current divine consciousness strength, at most, he can observe the appearance and appearance, facial expression, movement, and cultivation strength of cultivators within two realms of himself within 100 meters, if the other party deliberately conceals his cultivation, it will be difficult for him to detect.

The strange beast that was currently rapidly approaching him didn't mean to hide his cultivation, after all, it was not at the level of a spirit beast, and although it was a little cultivated, it was far from that wisdom.

The earth dragon python, the high-grade reckless beast, the degree of evolution is at the peak of the fierce beast and the real beast is only a line away, if you only talk about the cultivation of combat power, the lower grade can fight to refine the qi, and the middle grade can fight to build the foundation, and now this top grade is naturally warlike.

Xuan Fei secretly sighed unlucky, he knew that he would encounter this situation, so he would not be in a hurry, if he had broken through in the town and recovered his vitality before hitting the road, even if he encountered a beast of this level again at this moment, he would not even have a chance to escape. At this point, I have no choice but to fight hard.

With a whew, a huge head poured into the entrance of the cave, and a pair of blue-green eyes shone like emeralds, and at the same time, they opened their bloody mouths, wanting to swallow Xuan Fei alive.

It seems that this guy is extremely hungry, and he has already locked on Xuan Fei, just waiting to swallow it in one bite and fill his stomach. Xuan Fei is not the game in the forest, how can it be swallowed so easily. Although it is impossible to use the Yuan Qi actual combat spell, this reborn strong body is not to be seen.

Although the space in the cave is small, there are still many places that can accommodate Xuan Fei to dodge, Xuan Fei suddenly jumped up, jumped towards the top of the giant python's head, and his body tilted downward at sixteen degrees, just avoiding the stalagmites hanging down from the top of the cave, and then fell on the back of the python.

This series of actions were all planned by him before, and the initial appearance of his divine consciousness made his fighting consciousness much clearer, as the saying goes, hitting a snake and hitting seven inches, thinking about the weakness of this mutant earth dragon python will not make much difference.

When he flew and leaped, he had already tested the hardness of the python's head with the silver sparrow, and even a heaven-level mid-grade sword like the silver sparrow could not break through the heavy scale armor of the python's head, if he couldn't attack its weakness, I am afraid that he would definitely die. The Earth Dragon Python is worthy of being one of the most defensive beasts in the level of fierce beasts.

The earth dragon python missed, his temper became more and more violent, and he frantically shook his thick body and began to coil in a ring, this beast said that he was not enlightened, but he was not stupid, this action was obviously intended to entangle Xuan Fei, who had a slight advantage on his back, and catch the turtle in the urn, if Xuan Fei was really entangled in his back, it would be ······

Xuan Fei naturally won't let it succeed, if he can't even fight the instinctive thinking of an animal, and talk about the reincarnation of an executive, fighting with people, since it is a close control skill, as long as he is far away, he will not be hit, so he jumped again, ready to rush out of the hole, there is a lot of space outside, as long as he flexibly grasps the opportunity, maybe not only is it not easy to be hit by the winding skill, but he can also find a chance to escape.

However, what he didn't expect was that when his feet landed on the python's back, he had already been hit, this was a high-level fierce beast after all, how could it only use a physical attack stupidly, its armor had already been covered with earth-based spells, as long as it was touched, it would invade Xuan Fei's body.

Although the strength of the beast-level spell is not large, it cannot be eroded into Xuan Fei's body through a heaven-level sword like the silver sparrow, but Xuan Fei's shoes are ordinary cloth shoes, although the texture is exquisite, but there is no effect of magic resistance at all, this earth spell has a coagulation effect, Xuan Fei was just about to jump his body was frozen, and his feet slipped and fell into the coiled body of the earth dragon python.

The earth dragon python did not immediately open its mouth to swallow, but quickly tightened its body inward, which is exactly its usual style, first entanglement the prey and suffocating, and then slowly feasting.

However, Xuanfei Dantian Qi was empty, and he couldn't use the wood spell to relieve the stalemate of his body at the first time, until he was entangled by the huge body of the Earth Dragon Python and couldn't breathe, he had a little bit of consciousness in his hand, but at this time, he was already powerless to return to the sky, what was the use of regaining consciousness?

But he didn't want to give up, maybe there would be a miracle if he persisted, if he gave up, he would die, he used his strong body, and tried hard to resist the deadly entanglement of the dragon python, and he was stalemate for a long time, and the body's endurance finally reached the limit. This is also his body, if it were another foundation building cultivator, I am afraid that the bones of his body would have been crushed and shattered long ago.

With a poof, he threw his head up and spurted out a mouthful of blood, apparently his viscera had been damaged. Blood splattered down, partially scattered on the remnant dragon sword on his back.

The remnant dragon began to throb, making a dull buzzing sound, and then the sword body broke free from the entanglement and flew in the air, and the engraved dragon on the broken sword seemed to come back to life, twisting its body and breaking the sword.

The earth dragon python seemed to feel a great crisis, and its panic was no less than that of a mouse encountering a wild cat, and he actually ignored the food in front of him, hurriedly loosened the entanglement, and turned his head to think that there were signs of escape at the entrance of the cave.

The dragon could not allow it to escape, let out a dragon groan, and pounced on its body. However, the dragon was not an entity, and it penetrated after making contact with the Earth Dragon Python. I don't know what happened, but in a moment, the earth dragon python lost its vitality, and before it could even let out a wail, its huge snake head fell to the ground. The dragon's illusory form seemed to have become a little more real, and he returned to the remnant sword quite contentedly.

At this moment, Xuan Fei had already fainted, and when he woke up, he only saw a huge corpse and a beast core on the ground.

"Is this the so-called great calamity that will not die and there will be a blessing in the future?"

He was a little weak, but he was still very excited, no matter what happened just now, after all, his little life was saved, seriously recalling that it seemed that the remnant dragon suddenly flew up, as for how the remnant dragon killed the earth dragon python, he had already fainted at that time, and he didn't know at all.

Speaking of which, this unsightly remnant sword had already saved his life twice, and he remembered it deeply, he decided to find a suitable time to improve the quality of the remnant dragon with the current beast exterminating core after returning to the mountain, which should be regarded as a reward for his loyal protection.

As for the corpse of the earth dragon python, Xuan Fei planned to stew it little by little on the way and eat it, in his previous life, he had eaten a lot of snake meat, the meat was delicious, and he still remembered it and had an endless aftertaste, but I don't know what will happen to this mutated earth dragon python when it eats?

To his surprise, the flesh of this dragon python is not only delicious but also very beneficial to the recovery of vitality, no wonder the Pavilion Master of the Hundred Treasures Pavilion said that the flesh and blood of the alien beast can assist in refining the Zhuji Dan, and now the flesh and blood of this fierce beast level have been effective to this point without refining, not to mention the flesh and blood of the alien beast level, which shows the sincerity of the words of the Pavilion Master of the Hundred Treasures Pavilion.

Walking to the mountain gate, the meat of the dragon python has not eaten more than half, the sea of Xuanfei dantian qi has been filled, and he wants to have the potential to break the ranks.
