After eliminating a few foreign mercenaries and saving Long Linfei and the three of them, Ma Fan rushed to the southwest without stopping.

Ma Fan's divine sense can currently clearly perceive a radius of 100 meters, but his body has an innate perception of spiritual veins, spars, etc. At this time, he sensed that there was a faint spar aura in the southwest, and according to his experience, perhaps there was a crystal ore in the southwest. The spar contains a large amount of aura, which is a very common cultivation aid in the Haotian Continent, and can also be used as a circulating currency.

Soon, Marfan passed through the dense forest and came to a valley. There are some ruins left in the valley, which are already dilapidated. Apparently, it was once inhabited or inhabited by humans, but it has since been abandoned.

Ma Fan's divine sense sensed and found that there was a hidden hole under the cliff wall on the side of the valley. He went to the entrance of the cave and found a branch to pick up the weeds outside, and a brick wall was exposed.

Pushing open the brick wall, a swarthy hole was revealed.

Apparently, this is an abandoned mine.

Putting on his searchlight, Ma Fan entered the entrance of the cave. Stepping on the decaying track sleepers on the ground, Ma Fan sensed the aura in the mine as he walked.

The further you go in, the more abundant the aura.

Gradually, Ma Fan found that black lazuli appeared in the mountain next to the cave. I knew that about two kilometers further inward, the content of black lazuli increased.

This is what the middle-aged man called the Black Lazuli Mine. Finding the black gold mine, Ma Fan couldn't help but breathe a sigh of relief.

However, Ma Fan sensed that the further he went, the stronger the aura became. "Could it be that there is a crystal mine here?" Thinking of this, Ma Fan couldn't help but be overjoyed.

Although the spar was an extremely ordinary thing in the Haotian Continent, Ma Fan had never seen a spar on the earth. There is a lack of spiritual energy on the earth, and if the spar can be transported out, then the cultivation speed will be greatly increased in the future.

Thinking of this, Ma Fan couldn't help but speed up his pace and walked towards the depths of the mine.

After about 1000 meters, there is no road ahead. It seems that this is the deepest part of the previous mining.

However, Marfan did not stop. He sensed it slightly, walked over to the east wall, picked up a stone, and with a sharp force in his hand, the stone quickly smashed towards the wall.

"Wow... With a sound of dirt falling, a dark hole appeared in front of Ma Fan's eyes. A cold breath poured out along the mouth of the cave.

Ma Fan drilled into the hole. In the cave, the aura was several times more intense than in the pit just now.

The inside of the cave is uneven, but fortunately you can still pass through the lowest place. Ma Fan walked a few hundred meters along the winding hole before suddenly stopping.

In the darkness ahead, two faint green lights flickered.

"It turned out to be a low-level seven-star python, and it seems that this guy also knows how to use hedrons. Ma Fan's divine sense opened and found that there was a seven-star python in front of him, about ten meters long, and those two green lights were the eyes of this guy.

Ordinary seven-star pythons are just the most ordinary and low-level animals in the Haotian Continent, they don't have spiritual intelligence, and they can't even be counted as demon beasts. Only a very small number of seven-star pythons can evolve into demon beasts after absorbing spiritual energy for a long time.

Ma Fan walked towards the Seven Star Python.

Sensing the threat, the seven-star python raised its head and kept swallowing the letter in its mouth, its whole body curled up into an attack.

"Seeing that you have grown so big and know how to live in this pit, it is estimated that you have begun to have wisdom. Seeing that your cultivation is not easy, I will spare you today, you can go!" Ma Fan said to the Seven Star Python, and at the same time, a palpitating cold aura emanated from his body.

The seven-star python seemed to be unwilling in its eyes, but after feeling the cold air emitted by Ma Fan, the seven-star python let out a strange scream, and quickly twisted its body and retreated.

It is the nature of animals to seek advantages and avoid harms, and it seems that this seven-star python is not too stupid.

Ma Fan frightened off the seven-star python and continued to move inside.

Ahead, an empty space appeared. Everywhere the searchlight on Ma Fan's head went, many sparkling white crystals were embedded in the mountain.

"That's right, these are hedrons. Ma Fan couldn't help but get excited in his heart.

He hurried forward, pulling out a large hedron from the mountain in front of him. "Yes, it's still a medium-grade spar!" Ma Fan exclaimed excitedly. Rao is that he has lived in the Haotian Continent for eight thousand years, and he has countless high-grade spars and spirit crystals, but he actually found a spar mine in this barren place on the earth, which is enough to move Ma Fan. With these spars, Ma Fan would greatly speed up his cultivation and could even provide sufficient cultivation resources for his own forces in the future.

Ma Fan continued to advance inward until he could no longer go deeper. The Divine Sense carefully perceived it, and found that this hedron mine stretched for three kilometers, and it was impossible to perceive the depth of 100 meters downward, and it could no longer be perceived inward.

In addition to a large number of low-grade and medium-grade spars, Ma Fan also found some high-grade spars.

"It's here!" Ma Fan was inexplicably excited. Judging from the current distribution trend of the spar, the spar mine he perceived may be just the tip of the iceberg. "If it is a medium-sized or large-scale spar mine, it will be able to provide a hundred years of cultivation resources for an ordinary disciple of an intermediate sect in the Haotian Continent. Of course, if it was a medium-sized or large-scale spirit crystal mine, it would be able to provide a hundred years of cultivation resources for an intermediate sect disciple in the Haotian Continent.

At present, there is no instrument on the Haotian Continent that specializes in detecting spar mines and spirit crystal mines, and Ma Fan can only perceive the scale of the spar mine through his divine sense.

"According to my cultivation speed, the amount of spar I perceive at the moment can at least allow me to break through to the Jindan stage, what an unexpected gain! ”

Ma Fan took some high-grade spars and medium-grade spars and put them in his backpack. Then he took two more medium-grade spars, held one in each hand, and sat down cross-legged.

Each piece of medium-grade spar is equivalent to 1 card of medium-grade spar in Haotian Continent.

If it comes, it will be safe, Ma Fan is not willing to give up such a good opportunity to cultivate.

As Ma Fan ran the "First True Technique", a large amount of spiritual energy in the spar entered the body from both hands, constantly expanding Ma Fan's meridians and dantian, and then stored in various acupuncture points and dantian.

With a soft sound of "wave", Ma Fan felt that a layer of shackles on his body had been broken, his limbs and bones were refreshed, and his dantian suddenly doubled, and his meridians doubled accordingly.

"Breakthrough!" Ma Fan immediately threw away the spar in his hand that had already turned into powder, took out two more medium-grade spars, and began to absorb the aura in them. Ma Fan was surprised to find that after breaking through the quenching period in Haotian Continent last time, he had only absorbed the aura of 4 calories of medium-grade spars to stabilize the state of the early stage of the qi refining period, and this time he actually absorbed 16 medium-grade spars, which was equivalent to 16 cards!

The sensing range of the Divine Sense has also been expanded to 200 meters. He sensed his body, and saw that the aura in the dantian was like a liquid, and the meridians were getting wider and wider, and the aura that used to be gaseous was like a silver-white liquid at this time, roaring and surging in the meridians.

Ma Fan couldn't help but be surprised. This phenomenon will only appear when entering the foundation building period.

Could it be because he had entered the Qi refining method of quenching the body at the same time? Ma Fan didn't understand it at this time. However, he did not feel anything else unusual in his body.

Entering the Qi refining period, the speed at which the body absorbs the aura will be greatly accelerated, and the cultivators of the ordinary Qi refining period can release the aura and gather at one point to attack the other party, that is, the "gathering qi into a blade" that Ma Fan has reached before, but Ma Fan has reached this level before, and the power of the aura release will definitely increase exponentially at this time. After reaching the Qi Refining Period, the toughness of the physical body will be greatly improved, because at this time, all aspects of the cultivator's physical body have basically been finalized, and the level of cultivation in the future is closely related to the physical condition after the Quenching Period breaks through to the Qi Refining Period.

Sensing the surrounding ore again, although this time the range of divine consciousness was doubled compared to before, Ma Fan found that he still did not find the edge of the hedron mine within his sensing range.

Ma Fan packed up his things and quickly exited the cave, and it was already dawn outside. He carefully covered up the entrance to the cave and looked at it, still a little uneasy.

"It seems that we have to set up a formation to protect this place first. Ma Fan set his mind.

The arrangement of the formation requires jade as a guide, and Ma Fan came out this time without preparation.

"Caiyun Province has always produced jade, so why don't I go buy some to set up the array. After Ma Fan made up his mind, he immediately left here quickly.
