This evil cave is really a good place for Wang Chen. It is the most suitable place to hone himself.

The deeper he went, Wang Chen could feel the strength of the strange bird here. Although his body had changed from one foot long to a little more than two meters now, the Yin attribute smell of the strange bird was stronger and stronger.

Hiss!

The five elements magnetic divine light hit the strange bird. The strange bird was not crushed under the divine light as before. The luster of Yin attribute flashed on the broken body. Originally, some broken bodies soon recovered their original appearance, and the immortal spirit of Yin attribute around them also gathered on the strange bird.

"Interestingly, this strange bird has a magical power similar to Yin attribute. Although it is not complete, it looks a little like it. I just don't know whether there is mystery of Yin attribute in Yin crystal."

Wang Chen thought in his heart and killed him.

The Yin attribute is mysterious and difficult, which doesn't mean that it is the most powerful. It's like this strange bird. He doesn't understand how much yin attribute is mysterious at all, so his strength is not strong. Wang Chen has the power of refining his body and devours it. After welcoming him, he fought hard.

Especially the light black luster around Wang Chen's body, no matter what enters the range of light black luster, it begins to be suppressed and gradually swallowed up.

Although the strange bird has good strength, it is only an immortal realm after all. It is beaten by Wang Chen and has no power to fight back.

For a long time, the body of the strange bird beside Wang Chen stayed there motionless.

Reach out and knock out the Yin crystal in the strange bird's head, but Wang Chen is stunned, because this thing in front of him should no longer be called Yin crystal.

The light black round ball is also uneven, but it is obviously not a Yin crystal together, but like a round ball.

"Demon Dan?"

Wang Chen shook his head and said, "it's impossible. The demon pill won't be like this. It seems that the strange bird is also constantly cultivating and making progress. It seems that it has developed towards the trend of demon pill, but I don't know whether the strange bird in the realm of real fairy has a demon pill."

"If there is a demon pill, there is a divine mind. The strange bird can understand the mystery and refine the divine powers. Even if it is the lowest true immortal with no teaching and no communication by virtue of instinct, it is difficult to resist."

The strange bird has not yet formed a demon pill. It has the ability similar to a supernatural power. It is already the peak of heaven. If you go further, the demon pill must be the real fairyland.

True immortals, as the name suggests, are real immortals.

The immortal realm can also fly, but there are too many shackles in the fairy world, and they can't fly too high or for too long. For Wang Chen, it's very uncomfortable. Only when you get to the real fairy, can you fly freely in the high altitude of the fairy world.

More importantly, in the realm of true immortality, you will understand the fairy world, have the direction of future cultivation, and completely break away from the previous cultivation level.

Therefore, Wang Chen hesitated to go into the depths to have a look at the really immortal level strange bird.

"Forget it. First refine the demon pill of this semi-finished product."

Wang Chen put away the demon pill. At the next moment, the demon pill entered the world bead and began to refine slowly. The refining of this semi-finished demon pill was much slower than other Yin crystals, and the speed was only one tenth of that in ordinary times.

Therefore, it was not until an hour later that the semi-finished demon pill was refined.

At this time, the Yin attribute Rune of a semi-finished product in the boundary bead appeared, shining with a mysterious luster, slowly entered the depth of the boundary bead and disappeared.

Wang Chen also opened her eyes and showed a thoughtful look:

"The way of all things is really magical. Although this monster is not powerful, it can naturally understand the mystery of Yin attribute. Moreover, if it goes further, it can really produce wisdom. If there is an opportunity and continuous cultivation at that time, it will go further."

"It's just that the mystery of Yin attribute is rare. Ordinary friars can't understand it at all. If they kill more strange birds, they can understand the mystery of Yin attribute."

The yin-yang mystery, which is the avenue of yin-yang, is one of the most difficult mysteries to understand. Wang Chen has been practicing for so long, the yin-yang mystery is just an introduction, and there is no progress at all. Compared with other mysteries, it is like he has just understood one or two kinds of mysteries.

"Continue to hunt and kill this strange bird with Yin attribute. If you miss such an opportunity, you will regret later."

Wang Chen is also a decisive person. Even if there is danger, he doesn't hesitate to kill them, even if these strange birds have extraordinary strength.

However, even with Wang Chen's powerful body refining magic, these strange birds are not easy to deal with. Wang Chen also spent a lot of effort to solve one.

A month later, Wang Chen hunted and killed five strange birds at the peak level of immortals

One of the five strange birds was more powerful than the other. The last one had a faint tendency of metamorphosis. The pressure made Wang Chen a little stunned.

Only after refining five semi-finished demon pills, Wang Chen still felt a little dissatisfied, because there were not many Yin attribute runes among the five demon pills, or these Yin attribute runes were incomplete, and the number was still small, which was basically useless to Wang Chen.

"Do you really want to fight for a strange bird at the level of real fairy?"

Wang Chen thought in the bottom of his heart. Now there are two choices. If he doesn't leave quickly, there are many other demon pills outside. He's not afraid of not getting the mystery of the attributes of five elements and wind, thunder and ice, or he'll go deep. There are no demon pills for the strange birds outside, and there must be some strange birds inside.

A moment later, Wang Chen's look calmed down and decided to go inside and stop circling around outside.

The evil cave is actually a large underground cave leading to the underground. Wang Chen doesn't know whether it was formed by the fall of Xianjun, but according to the trend of the terrain, he can probably judge the trend near here and gradually enter the depths of the cave.

The immortal weapons with extremely cold Yin around are also more obvious. If you don't worry about the danger here, the friars who practice Yin attribute skill would be better to practice again.

Wang Chen went down step by step and looked around for the track of the real immortal monster.

"The strength of the monsters here is not high. It's a little difficult because of the mysterious Yin attribute, but it's much worse than the real experts. It can be inferred that the strange birds at the level of real immortals will not be too powerful, at least in real immortals."

Wang Chen was not unsure, so he went straight to find a strange bird at the level of Zhenxian.

At the beginning, which one of Gao Wudi and WAN beast Zun did not understand the immortal base, but also regarded as a strong person at the level of half a real immortal. Although his strength was strong, Wang Chen could not say that he had no power to fight back. After all, where was the mystery that Wang Chen understood.

Although he didn't know how the fairy base was formed, Wang Chen also knew that the fairy base must be high and low. The high invincible and the beast venerable must be relatively advanced, but other strange birds in the fairy world are not sure. They are probably not so powerful.

If this really immortal level strange bird is really as powerful as Qing'er's grandfather, Wang Chen doesn't dare to go deep into the cave.

However, Wang Chen underestimated the power of this really immortal level strange bird.

After walking for a long time, Wang Chen finally noticed the different Yin attributes and immortal Qi fluctuations in the distance, but a strange bird flew out.

The strange bird is only one meter long, but it looks very different from the previous strange bird.

This strange bird, with its feathers mixed up and down, has an air of yin and cold. It is very precise, like a black iron stone covering its body. It steals the essence in its eyes. It is obvious that it has even opened, which is no different from ordinary people's mind.

What's more terrible is the vision formed by the black fairy behind the strange bird. The vision is black and messy. It doesn't look very powerful. At least it's not a star and a half compared with the vision Wang Chen has seen before, but even so, the power on the vision is still very amazing.

"Fairy base vision..."

Wang Chen was shocked instantly, and his heart was relieved. This vision looked different from the magic vision, but the power was not even comparable to the medium magic power.

In the world of mortals, there will be visions when the lower magical powers are cast, but in the fairy world, visions will appear only when the perfect medium magical powers are cast, and they are not physical, but Xianji is no longer listed. No matter what kind of friars, as long as they cast their magical powers, there will always be Xianji visions.

"Well, after entering the fairyland, I didn't fight well. I just used this weakened version of the real immortal to test how much my strength has improved."
