The mysterious black and red metacarpal bone on Yin Yuanzhen's hand was the metacarpal bone of an ancient demon god, which was the same as Chen Shaofan expected.

The demon god is an existence equivalent to the level of a true god, and its metacarpal bones are naturally amazing.

If the demon clan can refine this metacarpal bone, it can greatly improve the strength and cultivation of the physical body, which is enough to dominate the Heavenly Saint Realm and the Saint King Realm.

Completely refining this bone, the probability of impacting the Demon God Realm will increase by at least fifty percent, and after reaching the Demon God Realm, it will be far stronger than ordinary Demon Gods.

The method of refining the metacarpal bone of the ancient demon god is to first punch this bone into the heart, and use the blood of the heart to conceive for three hundred and sixty-six days, that is, one year, so that the bone and the heart are completely integrated.

And the blood veins grow from the heart, connect to the demon bones, and begin to slowly absorb the power of the ancient demon gods in the refining bones according to the special law.

Of course, when refining this demon bone, there will be a certain risk, and the more you refine, the greater the risk.

The biggest test of refining demon bones is the power of the refiner's primordial spirit, willpower, etc., this process is very painful, and there will be extraterrestrial monsters to interfere with the mind, if you can't resist, it is very likely to go mad, cultivate to waste, and even die and die.

After Yin Yuan Zhenshen learned of these circumstances, his face did not show the slightest fear, but his face was full of excitement, and he said to himself: "Haha, I can finally refine this bone!"

"Once I succeed in refining, my strength will skyrocket, and I will be able to impact the realm of true gods, which is really great!"

Yang Yuan True Body looked at the excitement of Yin Yuan True Body, and couldn't help but remind: "Then you have to be careful, this bone, after all, is an ancient demon god's bone, and it is dangerous to refine." ”

"Don't worry, I have my own measure!" Yin Yuan said confidently.

The Yang Yuan True Body no longer had much to do, so he handed over the mysterious ancient animal skin that recorded the special refining method to the Yin Yuan True Body.

After doing all this, Yang Yuan's true body also came to the other side of the thirty-three times the Time Flowing Year Stone, and he looked up at the Qiankun Divine Sword Giant Tree that was finely carved from the Jade Giant Mountain, its branches and leaves swaying gently in the wind.

The jade leaves on the Qiankun Divine Sword Giant Tree were also shaking slightly, and so were the mysterious sword blades.

The most mysterious light cluster on the Qiankun Divine Sword Giant Tree, exuding a brilliant jade light, still appeared as a hazy state, and it exuded a terrifying and powerful coercion, which was very terrifying, if there was a god of destruction hidden in it.

This most powerful sword gourd, once it is successfully conceived and a new Qiankun Divine Sword is generated, Chen Shaofan estimates that even the Immortal King Ninefold Existence can kill the other party with a single sword.

However, it is not easy to breed this sword to success.

He devoured the headless corpses of eight Demon Saint Kings for the Qiankun Divine Sword Giant Tree, as well as a large number of corpses of demons such as the Demon Heaven Saint Realm and the Demon Earth Saint Realm, before forming a hazy light cluster.

It was completely conceived, and I don't know how many Demon Saint King-level corpses are needed.

Although, the Qiankun Divine Sword Giant Tree needed a huge amount of Heavenly Saint-level alien corpses to give birth to this sword gourd, but Chen Shaofan was confident that he could get it.

He thought that as long as he reached the realm of the immortal king, in his eyes, the ordinary saint king was a local chicken and a dog, and if he wanted to kill it, it was not a matter of being able to catch it.

After Chen Shaofan Yang Yuan's true body was true for a long time, he calmed down, sat down cross-legged, took out the huge amount of cultivation resources purchased from the Chaos Immortal Clan Commercial House, and began to refine and improve his cultivation.

On the body of Yang Yuan's true body, a dazzling red brilliance suddenly flashed, which was caused by the continuous operation of the Immortal Yuan Force, and the red brilliance was like a heartbeat, constantly contracting.

The aura it exudes, little by little, slowly intensifies.

And on the other side of the thirty-three times the Flowing Year Stone, Yin Yuan Zhenren held the black-red metacarpal bone of the ancient demon god in his hand, and looked at it with a serious look in his eyes.

After a few breaths, he pursed his lips and put the bone down for the time being.

Immediately afterwards, the hands of the Yin Yuan True Body danced according to a trajectory full of endless mysteries, and its body emitted a dazzling black and red light, and the Yin Immortal Yuan Force continued to circulate in the body, and countless black and red inscriptions flew and circled around the body, like black and red elves.

Yin Yuan's true body exuded a cold and evil aura.

As his hands continued to dance, black and red palm prints condensed out, floating in front of his body, and black and red inscriptions flying and hovering on top of the palm prints.

In the blink of an eye, there were nine hundred and eighty-one black and red palm prints, which were successfully condensed.

These black and red anthurium prints all stayed in front of you.

"Palm print aggregation!" Yin Yuanzhen's face was full of seriousness, and he snorted coldly.

As he spoke, all the palm prints suddenly gathered together like devout believers, turning into a brilliant black and red light cluster, and the cold and evil aura continued to diffuse, making people tremble, and countless black and red magic patterns were flying.

"Turn ——!" Chen Shaofan's Yin Yuan True Body snorted coldly again.

As his words fell, a cluster of black and red light erupted into a fiery light, distorting for a while.

Zilala!

Dense cracks appeared on the surface of the light cluster, and in the blink of an eye, the entire black and red light cluster was covered.

Bang——!

The light exploded, and a one-foot-long black and red dagger appeared in front of Yin Yuan's true body, and around this knife, there were terrifying creatures surrounded by phantoms: there were trolls with one-horned heads, demons with three heads and six arms, monsters with a lot of eyes, and ......

These demon creatures are phantoms, fangs and claws, constantly flying around the black and red daggers, and emitting a deafening roar.

Roar~~~

Roar~~~

This roar is hair-provoking.

Yin Yuanzhen looked at the strange black and red dagger in front of him, and without the slightest hesitation, his hands danced again, towards the part where his heart was.

Whoosh——!

The black and red dagger galloped towards the heart, and in the blink of an eye, the black and red dagger pierced into the skin, and the red blood gurgled out.

The black and red dagger continued to pierce inward, and more and more blood flowed out.

Yin Yuan's true body's brows furrowed slightly, obviously, this process was extremely painful.

However, Yin Yuan's true body will still be able to endure it, he continues to control the black and red dagger to cut the heart, which is a pain that pierces the heart - the real heart is like a knife!

Time flashed back a quarter of an hour, and finally, a hole had formed on the surface of his heart that was large enough for the bones of the black-red ancient demon god to fuse.

Scarlet blood seeped out, staining his robes red.

Yin Yuan's true body endured incomparable pain, reached out his big hand, grabbed the black and red demon bone, and pressed it hard towards the heart hole.

Ah——!h

The black and red devil bones were stuffed into the heart little by little, and the blood flowing out of the heart soaked into the black and red bones, and it burst out with blazing black and red magic light, and the grooves on it continued to wander away, as if they were alive.
