Even with the magic pickaxe, his mining speed is still very slow, almost a little more than a centimeter in an hour, so you can imagine how long it will take to open such a passage to the two worlds. While digging, he absorbed the pure demonic energy transmitted from another realm, enhancing and replenishing his own energy, which was very pure, and after entering his body, it turned into the essence of his growth.

Nalan Rongruo sighed as he dug as he found that as time went by, the sturdiness of this stone wall became stronger and stronger, and the amount of Yuan Force he consumed per pickaxe also increased.

Now he doesn't know how long this stone cave is, but he has to continue, as for the matter of the Demon Realm's invasion of the Cangtian Domain, for him, this is nothing, it is not a small matter at all, only strength is true, as long as he steps into another realm, he can have strong strength.

With strength, he can become the strongest existence in heaven and earth, and when the time comes, he will not need to hand over his fate to others, and he will not need to be subject to others everywhere.

In this damn place, he had been working hard, and he couldn't imagine how long it would take to open this passage.

After entering the Demon Cave, Yang Hong immediately felt that the pressure around his body suddenly increased, this Demon Cave was filled with a thick demonic energy, these demonic qi were somewhat mixed, some of them were Yuan Qi, and some of them were mixed together, and it was difficult for ordinary monks to absorb them, because absorbing the Demon Qi would make their Yuan Qi unstable.

[My lord, these demonic qi cannot be absorbed.] The Holy Spirit King found that Yang Hong was actually absorbing the demonic qi in the demon cave, so he shouted loudly.

[Don't worry, I'll be fine.] Of course, Yang Hong will be fine. He is a chaotic body that can fuse all kinds of qi and ten thousand laws. This demonic energy and vitality are naturally not a problem.

Yang Tienan placed a protective barrier around his body to prevent the demonic qi from getting close. However, the Holy Spirit King is not afraid of the demonic qi in this at all, no matter how he says it, he is also an ancestral god powerhouse, and the demonic qi of this sub-demon realm cannot erode him at all, but can be slowly absorbed by him.

Yang Tienan looked at Yang Hong, and also found that the latter could actually absorb the demonic qi here, and his heart was really tight, and at the same time he had a lot of curiosity.

The three of them traveled all the way, and suddenly they came to a fork in the road, which had three roads. Each road is exactly the same, and there is no difference.

[Now how do we go?] Yang Tienan asked.

[Wait a minute, I'll take a look.] Yang Hong cast the Taiyi Chaos Wheel of Life and began to search, he used demonic energy as a sensing medium and began to search.

The power of fate was pervasive, formless and insubstantial, and began to search the entire space continuously, and suddenly he found a cave. In the passage between them, the sense continued, and as he stretched for an unknown number of miles, he noticed a divine soul fluctuation. And it is also the fluctuation of the peak of the saint.

After discovering this, Yang Hong stopped and slowly withdrew his divine soul.

[Adult.] What did you find? The Holy Spirit King asked.

[There was a deserted Immortal Cave Mansion down here, and I went to explore it once.] But it's strange that with the power of my soul, I was turned away. Now there is a thick demonic aura here, and I don't know if the immortal mansion is still there. Yang Hong was a little curious when he thought of the Immortal Cave Mansion, and said in his heart how could this immortal not be destroyed in such a powerful demonic area, what was there in it.

Yang Tienan asked suspiciously: [Immortal Cave Mansion? How can there be an immortal cave here, if it is a saint cave mansion, I will still believe it, the immortal cave mansion is absolutely impossible, how can the immortal qi resist the demonic qi. ]

[yes, I think it's weird, and it's impossible.] Yang Hong said.

[My lord, I think this situation is very simple, that is, this god and demon passage has only recently begun to infiltrate the demonic qi here, so the demonic qi has not completely destroyed it. The Holy Spirit King said.

[It is possible that this is the case.] Yang Hong agrees.

[Indeed, it is possible that there is something that caused the demonic energy to leak out here, which is why this is the case.] Yang Tienan said while supporting Yuan Li and resisting the demonic qi.

[By the way, there is a place here where I found a divine soul fluctuation, and it seems that this is the reason for the leakage of demonic energy.] Yang Hong said.

[Really?] Looks like we're going to take a look. Yang Tienan said.

[Of course, let's go, I'll lead the way.] Yang Hongdao.

So he took Yang Tienan and the Holy Spirit King and flew towards the depths of the demon cave in the middle.

After flying for a while, Yang Hong and the others actually came to a vast forest, which Yang Hong had not observed before, because the demonic qi had the effect of weakening the divine soul.

[I know what this place is?] Yang Tienan said suddenly.

[Oh, where is this?] Yang Hong asked.

[This is the Subdemon Realm, I've been here before.] Yang Tienan said.

[Sub-Demon Realm?] ]

[Yes, it's the Subdemon Realm!] It's just that at that time, the path was different, and it was directly used for cross-border with spatial positioning, and now that I am walking like this, I found out that the sub-demon world is actually caused by the channel of gods and demons. Yang Tienan fell in love with Shaomeng at the beginning, and the two were together and traveled to many places.

[Ancestor, you shouldn't have the strength you have now, right?] Yang Hong released his soul and began to observe the area, and then said.

[Of course not, at that time, I was just the peak of the saint, entered the sub-demon realm, and once had a big battle with several emperors in the demon world, although this sub-demon realm is small, but because of the benefit of the demonic energy, the ordinary strength is very strong, and they all have the qualifications to achieve the strongest, if the god and demon channel is opened, their strength will increase by leaps and bounds. Yang Tienan replied.

[In this way, it is possible that this place used to be the same as other planes, but later due to the demonic energy, it became the sub-demon realm, right?] Yang Hong glanced at it and found that the area of the Sub-Demon Realm far exceeded that of the Heavenly Emperor Mountain, and his current soul power could not be fully enveloped.

[Yang Hong, this was not the case here, only the central area is demonic qi, and other places are normal, there are many powerful holy beasts, I don't know if they have become demonic beasts now. Yang Tienan said that he recalled the good times in the past and recalled his lover.

[My lord, I found a huge portal in the center, and many warriors were gathering in front of the portal, as if they were going to fight.] The Holy Spirit King's cultivation was the strongest among the three, and he could naturally sweep all the abnormalities, which was for Yang Hong, and he only needed one breath to be able to collect all of them in the sea of knowledge.

[It seems that these emperors of the sub-demon realm can't sit still, and they are also going to start a war.] Yang Hong did not hesitate, and directly thought of the crux of the problem.

[The great calamity is coming, and all living beings will be doomed, and no one can avoid it.] Yang Tienan sighed, his face full of sadness. (To be continued......)
