After finishing the conversation with the Chaos Bead, Ye Feng opened his eyes and looked at the dragon vein in his hand, strictly speaking, this dragon vein is not prohibited, it is not a magic weapon or a spiritual treasure, at most because of its particularity, it can be regarded as a thing that suppresses the luck of the Central Plains.

Originally, even if there was the backbone of the Pangu Great God in it, it would be extremely easy to use the Hair of the Refining Magic Weapon to refine it in this environment.

It's just that the place where the mausoleum of the Yellow Emperor in Lingyun Cave is located is extremely special, it is the place where the luck of the Central Plains gathers, and it is also the place where all kinds of killing, blood, resentment and other demonic qi converge, and the dragon vein has been in it for thousands of years, absorbing the demonic energy, righteousness, and spiritual energy, and forming a delicate balance in it.

And because the dragon vein is not a magic weapon and a spiritual treasure, there is no prohibition, which makes this balance extremely fragile, and if you don't pay attention to it, it will break this balance, causing the internal energy of the dragon vein to be disordered, and even if it is the spine of the Pangu God, it will be damaged.

This made it extremely difficult for Ye Feng to refine the dragon vein.

Now that Ye Feng wants not to damage the dragon vein, and wants to refine the dragon vein, there are only two ways to go.

The first is to depict the prohibition for the dragon vein, and with the help of the backbone of the Pangu god, the dragon vein will be refined into an acquired spirit treasure, but not to mention that Ye Feng can't refine weapons, even if Ye Feng is proficient in refining weapons, with Ye Feng's current cultivation, except for ruining such a good embryo as the dragon vein, he can't refine anything at all.

The second is to completely absorb the demonic energy, righteous qi, and spiritual energy in the dragon vein, and there is no need to worry about energy disorder if there is no energy inside the dragon vein. It's just that in this way, the dragon vein will lose the effect of suppressing the Central Plains' Qi Luck, which is equivalent to the Central Plains losing a thing that suppresses the Qi Luck.

Although it is said that the Heavenly Dao of the Wind and Cloud World is incomplete and almost non-existent, the impact of the power of luck on the country and forces is minimal, even if there is no suppression by the dragon vein, it is not a big deal. But the Fengyun World also has the will of heaven and earth condensed by the will of all beings in the Central Plains, once someone damages the things of luck, they will definitely be disliked by the will of all beings, abandoned by heaven and earth, and it will be difficult to do things in the future.

In addition, without the dragon vein to absorb the demonic qi of the Central Plains gathered here, this will inevitably leave a huge hidden danger and leave the Central Plains behind. Ye Feng is not a ruthless and hard-hearted person, so he naturally does not want to do such a thing for his own selfishness.

For a while, Ye Feng couldn't help but fall into silence, thinking about whether there was any way to get the best of both worlds.

Hey, that's right.

Suddenly, a flash of inspiration flashed in Ye Feng's mind, and he remembered the He's Bi and the Evil Emperor Relic that he had obtained in the Double Dragon World. Since the energy in the Heshi Bi and the Evil Emperor Relic was absorbed by him, Ye Feng made it into ornaments with the Heshi Bi and the Evil Emperor Relic and kept it on his body.

Isn't it just the right time to come in handy now? As the jade seal of a country, Shuanglong Zhonghe Bi is somewhat known as "the treasure house of Heshi Bi and Yang Gong, and if you get one of them, you can win the world", which is not exactly a thing that suppresses luck. The Evil Emperor Relic can store the True Qi Essence and Demon Qi, which is not just absorbing the Demon Qi gathered from the Yellow Emperor's Mausoleum.

Ye Feng's heart was excited, he took out the He's Bi and the Evil Emperor Relic that were made into ornaments, ran **, carefully sucked out the same amount of righteous qi aura and demonic qi from the dragon vein, and then used himself as a transit station to refine the remaining righteous qi and demonic qi of the aura, and then injected the righteous qi and demonic qi into the He's Bi and the Evil Emperor Relic respectively, stimulating the abilities of the He's Bi and the Evil Emperor Relic.

In order to verify whether it was effective, Ye Feng used his mana to drag the Heshi Bi and the Evil Emperor Relic up, and operated according to the arrangement of the green vitality ball and the gray death qi ball in the dantian.

Suddenly, He's Bi and the Evil Emperor's relics emitted dazzling brilliance, and they directly broke free from the shackles of Ye Feng's mana, rose to the sky above the Yellow Emperor's mausoleum, and spun rapidly, and the aura, righteousness, and demonic qi in the mausoleum were immediately pulled and gathered around He's Bi and the Evil Emperor's relics, and were absorbed by them.

After a long time, the rotation speed of He's Bi and the Evil Emperor's relics gradually slowed down, and finally maintained a stable rotation speed and stopped above the Yellow Emperor's mausoleum, absorbing aura, righteousness and demonic qi at a uniform speed.

Phew! Ye Feng's heart was relaxed when he saw this, so that the dragon vein really belonged to him, and even if the dragon vein was damaged, it would not have the slightest impact.

Next, Ye Feng should do his own thing, Ye Feng picked up the dragon vein and thought about it, this Yellow Emperor Mausoleum is rich in spiritual energy, the place is secret, anyway, after his Five Elements Refining Body Technique is promoted to the fifth layer, he can almost no longer need food, so it seems that the Yellow Emperor's Mausoleum is just the best place to refine the dragon vein and cultivate.

If you want to do it, you can do it, immediately Ye Feng sat down, spread the dragon vein with both hands and placed it in the dantian, and then ran ** to absorb the spiritual energy and demonic energy in the dragon vein.

For the aura, Ye Feng used the Five Elements Body Refining Technique to refine the body, while the Demon Qi and Righteous Qi, Ye Feng tried to introduce it into the Dantian Vitality Ball and the Death Qi Ball first, to see if the two balls were absorbed, if not, Ye Feng would expel them and let the Heshi Bi and the Evil Emperor Relic absorb them.

To Ye Feng's surprise, this time when he channeled the righteous qi and demonic qi into the vitality ball and the death qi ball, the vitality ball and the death qi ball spun rapidly, but the vitality ball and the death qi ball did not absorb the imported righteous qi and demonic qi, but the death qi ball quickly split into two small balls as it rotated, one ball contained pure dead qi, and the other ball contained all the demonic qi that Ye Feng had absorbed before.

As soon as the three small balls were formed, they quickly rotated according to the three-talent formation, the demonic qi was absorbed by the demonic qi balls, and the righteous qi was surrounded in the center by the three-talent formation formed by the three small balls of vitality, death qi and demonic qi, and they were constantly compressed as the three small balls continued to rotate.

I don't know how long it took, but as the righteous qi was continuously absorbed and compressed, the righteous qi also formed a small ball of righteous qi. After the righteous qi formed a small ball, the three-talent formation composed of the three small balls of vitality, death qi, and demonic qi also changed rapidly, and became a four-elephant formation composed of vitality, death, and righteous demonic qi.

After the formation of the Four Elephants Formation, Ye Feng's dantian also underwent great changes. The yin and yang mana was quickly compressed into the four-elephant formation formed by the four small balls, forming two yin and yang mana balls respectively.

Ye Feng was startled when he saw this, he was deeply afraid that after the mana formed a yin and yang ball, it would be out of his control like a vitality and death qi tactic, so he hurriedly tried to mobilize it.

Fortunately, what made Ye Feng happy was that the Yin Yang Mana Ball did not appear in the same situation as the Vitality Ball.

Ye Feng 'watched' the more and more magical changes in his dantian, and couldn't help but think of such a sentence in his mind - Wuji gave birth to Taiji, Taiji gave birth to two yi, two yi gave birth to four elephants, four elephants gave birth to gossip, and gossip gave birth to Qiankun.

Thinking back to the discovery process in his dantian, after entering the Tao, he created martial arts, cultivated yin and yang, and the yin and yang of the dantian converged and compatible, and later comprehended and comprehended the law of yin and yang.

Thinking like this, Ye Feng couldn't help but feel excited.

It's just that when Ye Feng looked at the ball of unicorn essence blood next to the demonic qi ball, Ye Feng became entangled again, what is the matter with this unicorn essence blood? The four elephants are Qinglong, White Tiger, Vermilion Bird, and Xuanwu, but I haven't heard of a unicorn?

Am I delusional?

Forget it, don't think about it, let's go with the flow and see what changes in the future.

Ye Feng shook his head, calmed down his ups and downs, and continued to devote himself to refining the dragon vein.
