Calm down!

Liu Lang figured out the key to this, and immediately poured all his mind into the yin and yang ball.

As time passed, the yin-yang ball became smaller and smaller, and finally it seemed to condense into a walnut-sized yin-yang ball, half black and half white.

In the soul domain, Liu Lang slowly stretched out his hand and touched it lightly.

"Boom!"

There was a violent roar from the entire soul domain, and the yin and yang ball contained a majestic power comparable to that of a mountain.

Liu Lang just touched it for a moment, and suddenly felt shocked.

This kind of power is completely different from the yin and yang balls that were previously presented in a semi-void state.

I think that for the power that was only like a grain of rice contained before, this power is simply comparable to Haoyue, and it is unstoppable.

Empty Ming.

At this moment, Liu Lang was completely caught in the emptiness.

Outside, Mu Tucheng looked at Liu Lang, but when he saw Liu Lang cross-legged and closed his eyes, he didn't even feel like he was breathing.

However, as a ghost puppet, Mu Tu Cheng clearly felt that the pressure Liu Lang gave him was rushing upwards like a rocket.

It wasn't until later that Mutu City seemed to be overwhelmed by that pressure.

"Oh my God, that Yuan Dan is so fierce? And the owner didn't even react in the slightest? ”

Wood Slaughter City was shocked.

According to Mu Tu Cheng's idea, since that black thing is the legendary Yuan Dan, it will definitely have a violent reaction for a period of time if swallowed in general, and there will even be a painful feeling of accepting foreign objects.

However, for Liu Lang, it was as simple as eating a bowl of rice, and there was no discomfort at all.

Of course, Mu Tu Cheng didn't know that the two qi of yin and yang that Liu Lang had learned was the foundation of all things, the source of the world, and the higher the level of things, the stronger the absorption power that burst out.

As the saying goes, if the enemy is strong, I am stronger.

In the face of yin and yang, there is nothing that cannot be solved.

Mu Tu Cheng couldn't see any changes in Liu Lang's body, but the stupid bird seemed to be able to penetrate Liu Lang's body, constantly giggling, and a pair of eyes stared at Liu Lang's dantian without blinking.

After another two hours, Liu Lang's whole body was soaked with sweat, as if he had steamed a sauna, and even his skin had a metallic feeling.

"Hoo ......"

Liu Lang let out a long breath, slowly opened his eyes, looked at Mutu City, and then looked at the stupid bird.

Those eyes were clearer than before, but they were like a deep well that Gu Bo was not shocked, with a depth that people couldn't see through.

Seeing that Liu Lang suddenly woke up, Mutu Cheng was overjoyed and was about to speak, but Liu Lang waved his hand.

"Wood Slaughter City, from today onwards, you are no longer a dog in my eyes, but my subordinate!"

Liu Lang said as he slowly stood up, didn't even look at Mu Tucheng again, but walked up to the stupid bird, raised his hand and stroked the stupid bird's head, and said lightly: "Thank you this time." ”

"Cluck, cluck."

The stupid bird jumped and jumped excitedly, obviously happier than Liu Lang.

Although it only took half a day, Liu Lang's body had already undergone earth-shaking changes.

Chizi Xin's Yuan Dan was almost completely absorbed.

Not to mention other aspects, just this ability to absorb the power of Yuan Dan, if anyone who knows the inside story sees it, they will definitely be surprised.

Generally speaking, Yuan Dan is the essence of a person's cultivation and the source of a monk's strength.

And once Yuan Dan is taken out, most people will use it for refining.

But this refining process is very different, even if other people can obtain the Yuan Dan, the power they can refine is only one-tenth or twelve of the original Yuan Dan, and even if it is an extremely strong monk, it is already a very shocking number to be able to refine half of the power into use.

However, Liu Lang refined more than ninety percent of it without much effort.

Although Liu Lang's cultivation on the surface is not obvious now, the transformation of his body is not the same at all.

Now it is more than enough for Liu Lang to kill a ghost king-level existence with one punch.

It's just that although that Yuan Dan was refined, it would take quite a long time to truly absorb it.

What surprised Liu Lang even more was that a walnut-sized Yin Yang Yuan Dan had been formed in his dantian.

This Yuan Dan is completely different from the black of Chizi Xin.

Chizi Xin's Yuan Dan is mainly based on ghost qi, and it is also the source of ghost qi cultivation, and it is called a ghost heart by many monks in the underworld.

Once you cultivate the ghost heart, your strength will increase dramatically.

And Liu Lang's Yuan Dan not only contains the power of the ghost heart, but also has abundant yang energy.

With this power, Liu Lang absorbed the power of the sixth spirit in one fell swoop and was promoted to the level of a middle-grade ghost king.

In other words, now if Liu Lang is willing, he can accommodate six ghost puppets in his body, and the improvement of combat effectiveness is definitely not a little bit of a star.

However, Liu Lang also clearly knew that he, a middle-grade ghost king, could only be regarded as a rookie under a higher-level cultivation system.

Putting away the excitement in his heart, Liu Lang put his hand into his pocket, carefully put away the hair left by Bai Qi, and then took out the Yan Fu Dou diagram, and put together the Yan Fu Tu diagram that he got from the giant tree.

Fortunately, the material of this Yan Fudou diagram is special, and it has not been burned under such a blazing flame, and it is still intact.

Mu Tu Cheng looked at Yan Fu's Tu Tu and couldn't help but step forward curiously, "Master, this is the legendary Yan Fu Tu Tu Tu that can open the seal of the corpse clan?" ”

Liu Lang nodded, holding the still incomplete Yan Fu Tu diagram, stretched out two fingers with one hand, measured the mutilated place, and muttered: "Judging from the current map, this terrain is not the Kunlun realm at all, it seems to be a netherworld." ”

A thousand years ago, although Liu Lang was a young son of the underworld, he was an extremely gentlemanly second son, and he almost didn't care about the affairs of the underworld, so he was not very familiar with some handsome people such as leopard tail.

However, at that time, Liu Lang had almost visited the entire Netherworld, but he had a considerable understanding of the vast Netherworld.

Although it has been separated by thousands of years, there are also faint memories flashing in it, looking at Yan Futu's diagram, Liu Lang has a feeling of understanding.

Except for the fragments, this picture looks a lot like the Netherlands.

Mu Tu Cheng was puzzled: "Young master, could it be that the corpse clan is in the Netherworld?" ”

Liu Lang shook his head: "I don't know much about this, but looking at the size of the missing part, there should be two or three pieces left to make it up, and when the time comes, we will know." ”

As he spoke, he slowly folded it up, and then reached out and picked up the fire feather sword that fell to the ground next to him and slashed it with the immortal.

Liu Lang has seen the power of this fire feather sword with his own eyes.

It was precisely because of the sudden power of this fire feather sword that Liu Lang was able to take the opportunity to kill Chizi Xin with an immortal.

However, the Immortal Slash, which had been used for so long, was a little uncomfortable if he suddenly switched to a sword.

"Wood Slaughter City, tell me the meaning of those twelve words you said on the canopy of the giant tree."

Liu Lang looked at the Fire Feather Sword and said lightly.
