Starting from the martial arts world, Gan became a true master of martial arts.

Chapter 527: Yin and Yang Alternation
The passage was very deep, and the huge mine was like a huge mouth of an abyss, swallowing up even the surrounding light.

Fang Xuan didn't know how long he had been walking down. At a glance, he still couldn't see the end of the stairs.

However, as we continued to go deeper, wind and waves gradually surged out from below, mixed with a very rich spiritual energy.

Looking at the abyss-like mine beside him, Fang Xuan couldn't help but sigh: "No wonder Xuan Crystal is so precious!"

Yuan Dan also smiled, knowing what Fang Xuan meant. "Ever since our ancestors discovered the sacred stone a thousand years ago, our clansmen have been digging for it. Unknowingly, we have dug so deep in the past thousand years."

"The difficulty of mining holy stones has increased dramatically in recent years, and the demand for black crystals within the clan has gradually fallen short of supply."

"But some places have to use the holy stone, and I don't know what to do after this mountain is hollowed out."

Seeing Yuan Dan's worried look, Fang Xuan also fell silent.

You don’t need to worry about the future of the Immortal Clan.

The two walked for a while, and Yuan Dan said, "In fact, the tribesmen have always found a way to mine the holy stone, no matter how deep they dig."

"But as we continue to dig deeper, more and more impurities are found in the holy stones. At the beginning, the ancestor could still find ways to remove the impurities, but in recent years, the impurities have become more and more difficult to remove."

Fang Xuan thought for a moment and asked doubtfully, "If that's the case, why don't you continue to seek a solution from Yu?"

Yuan Dan shook his head and sighed, "Yu's method can only maintain everyone's cultivation by sacrificing a few people. Although there are hundreds of thousands of people in my Changsheng clan, there are less than one-tenth of them on the ground."

"There are too many unstable factors. The number of demon possessed prisoners in the Holy Prison has been increasing over the years. How dare we use Yu's method?"

Apparently, the Changsheng Clan had known for a long time that Yu Clan had helped them remove impurities from the Holy Stone, but they had not taken it seriously. Coupled with the huge demand for the Holy Stone within the clan, the tragic incident of the Yu Clan's rebellion by the possessed demon finally occurred.

Hearing Yuan Dan mention the Holy Prison again, Fang Xuan asked in confusion: "From what you said, the Holy Prison has been holding the possessed for over three hundred years. Haven't you tried to solve this problem?"

Yuan Dan looked worried and shook his head heavily, "Of course there are some, but these evil spirits are extraordinary, even the ancestor can't get rid of them, and generally, possessed demons are extremely difficult to kill."

"Under desperation, the First Ancestor turned the former holy land into a holy prison to imprison those possessed by demons. That place gradually became a forbidden area for the tribe."

Fang Xuan remained silent. He did have a way to refine the demonic energy, but it would consume a lot of energy on himself. If there was no exchange of something of equal value, he would naturally not help the Immortal Clan for no reason.

clatter! clatter! clatter!
On the steps on the right bank, only the sound of two people's footsteps could be heard.

About four hours later, the two finally touched the ground.

The moment his feet touched the ground, Fang Xuan's heart sank.

The sticky spiritual energy of heaven and earth penetrated the earth-brown surface, continuously flowed along the soles of Fang Xuan's feet, and into Fang Xuan's body.

Yuan Dan did not notice anything unusual. He pointed his finger at Fang Xuan and said, "The holy stones on the east side have fewer impurities. There have been harassments from outsiders these days, and the tribesmen have not come down to mine stones. Senior Fang, please go ahead and mine them yourself!"

Fang Xuan turned around and bowed to the other party, saying with a smile: "Thank you very much!"

After saying that, Fang Xuan walked directly to the east. After walking a few hundred meters, a deep hole appeared in front of him. After walking another hundred meters, he saw the uneven surface of the black crystal that had been mined.

Fang Xuan stretched out his hand and tried to pry open a bulge, but the black crystal, which didn't look solid, didn't move at all.

After thinking for a moment, Fang Xuan directly summoned Mo Yuan.

The ink light quickly passed across the surface of the rock, and soon hundreds of knee-high rocks rolled down. Fang Xuan swung Mo Yuan again, and as the sword light continued to dance, the huge rocks were cut off layer by layer like tofu.

After a while, several fist-sized black crystals rolled to Fang Xuan's feet.

Fang Xuan finally understood why the Changsheng people were able to dig such a deep mine in just a thousand years.

There aren't many black crystals in this mine. Often, only a fist-sized piece of black crystal can be dug out from one cubic meter of rock.

He took these pieces of black crystal in his hand and activated the Samadhi Divine Fire in his body. The blue-purple flame rose rapidly, and in an instant the earth-brown skin was completely refined.

The star-like black crystal was completely exposed in front of Fang Xuan. In the nebula-like substance, there was still a mass of black mist.

hum!
The flames surged, and the black mist soon dissipated completely under the refining of the Samadhi Divine Fire. The few pieces of black crystal also turned into a few drops of sticky crystal liquid, which were crystal clear and floated in the air under the drag of a strong energy.

After doing all this, Fang Xuan sat cross-legged on the ground, and then concentrated his spiritual consciousness. The more than 200 acupoints in his body that had been opened up were like more than 200 bright stars, floating in front of Fang Xuan.

"Finally we've reached this point."

He calmed down and exhaled slowly.

Since he started practicing martial arts, he has relied on his extraordinary perseverance and ability to open the gates of heaven, temper his muscles and bones, and temper each realm to the limit, the limit as a human being. Now, he is finally about to make a breakthrough to the ninth-grade martial arts master.

This is the real threshold between Martial Master and Divine Wandering Realm!

Perhaps it was because Fang Xuan had been pursuing the limits of his body in every realm before, which allowed him to now reach the realm of Martial Honor and open up the nine divine acupoints such as Tianshu, Xuehai, Neiting, and Taixi that other warriors could not reach.

Although martial arts have been developing all the time, it is not certain that in the next thousands or even tens of thousands of years, there will be people who will be able to meet the conditions to open the nine sacred acupoints like himself, let alone complete this step.

This is too difficult!
He swallowed the few drops of crystal liquid in front of him in one gulp, and then took out the spiritual liquid from the spiritual wood from the small object, and swallowed it all down as if drinking wine.

A warm feeling instantly flows along the esophagus and gathers towards the Dantian Qi Sea, then passes through the Dantian Qi Sea, starting from Tianshu, Taiyi, Guanmen, Lingxu, and then flows through more than 200 acupoints in the body.

As a large amount of crystal liquid and wood spirit liquid entered Fang Xuan's body, Fang Xuan could feel that the muscles and bones all over his body were becoming active, exuding a strange vitality.

After a few drops of crystal liquid were quickly absorbed, Fang Xuan mined new black crystals again, and the cycle continued.
"Extreme yin becomes yang, extreme yang turns to yin, yin and yang rotate, this is the great way."

Fang Xuan felt the constant changes in the Qi sea in his Dantian. The Qi sea, which was like yin and yang, also began to spin rapidly as the majestic spiritual energy poured in. He couldn't help but murmur in his heart.
