Since Chen Feng's sword forging technique entered the fourth level, he could directly ignore the attacks at the level of the Yunling Realm, so Chen Feng had the confidence to resist Yang Fengxiao's sneak attack by Zhou Wolong.

Of course, the reason why he wanted to do this was not just to pretend to be forced, but more importantly, to better deter Xuan Qingzi and the others of the Qingcheng faction.

He knew from Yang Fengxiao, Zhou Wolong, and the Purple Eagle King that the Qingcheng faction had an Ancient Immortal Cave Mansion, so he naturally hit the idea on the Immortal Cave Mansion.

By showing your strong strength through the station, then you can better achieve your own goals.

Chen Feng has traveled most of the world and traveled to many places, but it is the first time he has heard of the Immortal Cave Mansion, and it is false to say that he is not impressed.

But the more important reason why he did this is not just because of himself:

Ever since he knew that the old demon of Black Mountain was cooperating with the sect master of the Corpse Refining Sect, he had already guessed that now that the start time of the plot was approaching, even if he had already made many changes in Ning Caichen, but the latter was his only friend, Chen Feng could not be completely at ease, and he was ready to experience that with Ning Caichen.

However, before that, Chen Feng must first improve his strength.

Although the tree demon grandma is nothing, the old demon of Montenegro behind it is definitely a ruthless external strengthener, after all, this is an existence that can be called king in the underworld.

Not to mention that there is a centipede spirit that dares to bewitch the king, disturb the court, change as it comes, and blaspheme the gods, and its cultivation is definitely not lower than the old demon of Montenegro, or even stronger.

The king of the world has his own Ziwei Emperor Star guard, with his own imperial aura, not to mention the general monster, even if he is close, he will be injured, and the centipede essence can do this, and its cultivation, in Chen Feng's opinion, may even be in the realm of Hedao, close to the immortals.

In the past, Chen Feng's cultivation was insufficient, so he allowed these monsters to make trouble, and at most he could only kill and destroy the monsters he saw, but now that his cultivation has been raised, if he signs in the Ancient Immortal Cave Mansion and finds anything good, he believes that he will definitely have the ability to deal with these monsters at that time.

After seeing the strong strength that Mr. Chen deliberately displayed, Qing Xuanzi was very obedient and agreed to Chen Feng's request, and immediately took Chen Feng to the Ancient Immortal Cave Mansion inherited from the Qingcheng faction.

This cave mansion is very hidden, and it is also strictly guarded by the Qingcheng faction, except for the head and a few elders, basically, few people come here.

However, because of Chen Feng's actions to protect the Qingcheng faction and his strong strength, Qing Xuanzi had to bring Chen Feng here even if he didn't want to, for the sake of his own life.

Walking into the Immortal Cave Mansion, sure enough, I felt that it was immediately different from the outside, not only was the aura more intense, but Chen Feng also felt that his various states had also improved slightly, his spirit was also more invigorated, and his understanding of the exercises was more thorough.

I have to say that it is worthy of the cave of the ancient immortals, and it is really very strange.

After carefully feeling the changes brought to him by the Cave Mansion, Chen Feng also began to look at the internal structure of the Immortal Cave Mansion.

This is a cave house supported by 4 stone pillars, its area is about 200 square meters, the ground is a large flat stone, the stone is hard, but there are some words and formation inscriptions that Chen Feng can't understand.

Not only on the ground, but even the stones on the top of the head are also carved in this way, corroborating each other with the ground, faintly, connecting the entire cave as a whole.

And in the middle of it, there is a futon, which has long been dilapidated.

Just from the appearance, it can be seen that this thing has been inherited for a long time, and it has long been unknown that there are too many teenagers.

I think that it can be passed down to this day, and it is also because of the remnants of the breath of the ancient immortals, so that the futon has some special characteristics.

Other than that, there was nothing else in the entire cave.

"This Ancient Immortal Cave Mansion is powerful to say, but in fact, it is just an empty shell, otherwise, my Qingcheng Sect would not be until now, and it is only a first-class sect in the cultivation world, and it has not yet achieved the status of leading the group."

Qing Xuanzi followed behind Chen Feng and explained the same to him from time to time, but in his heart, he didn't want Chen Feng to have too much contact with the Ancient Immortal Cave Mansion, so he also deliberately said some mediocre things about the Cave Mansion.

However, Chen Feng didn't care what he said, he had already made up his mind to stay in this Ancient Immortal Cave Mansion for a few days, waved his hand, let Qing Xuanzi go out first, and began to sit in the cave mansion, closing his eyes and meditating.

Seeing this, Qing Xuanzi could only retreat helplessly, he couldn't destroy the Ancient Immortal Cave Mansion because of Chen Feng, not to mention, after seeing Chen Feng's strong strength, he couldn't afford to have such a thought in his heart.

Moreover, Chen Feng had already stated that he would only stay in the cave for 5 days, and after 5 days, he would have nothing to do with the Qingcheng faction.

After Qing Xuanzi and the others withdrew, Chen Feng said to the system in his heart: "I want to sign in to the system." ”

An electronic voice sounded in Chen Feng's mind: [The host has successfully signed in, congratulations to the host, and he has obtained the Immortal Ascension Diagram. 】

"Ascension Immortal Diagram? Interesting, I want to see, what is this immortal ascension diagram? ”

Chen Feng had already heard the prompt of the system, and he had already guessed that this immortal ascension diagram was really related to the ancient immortals, so he couldn't wait to open the immortal ascension diagram obtained by signing in the system immediately, and looked at it with fine eyes.

There is true meaning in the volume, but there is no dust at a glance.

Half a day later, Chen Feng withdrew his experience from the Immortal Ascension Diagram, his face full of admiration:

"So this is the Immortal Ascension Diagram? Sure enough, the exercises left by the ancient immortals are endlessly mysterious, even if it is a great water song cultivated by a super power like the Xuanshui Sword Immortal, who is already in the realm of the Dao and is extremely close to the realm of immortals, it is far from being able to compare with the Ascending Immortal Diagram, and it is even heaven and earth at all. ”

It turns out that this immortal ascension diagram is the practice practiced by the ancient immortals, and it is a practice that can really be cultivated to the realm of immortals, and when the cultivation reaches the extreme, it can even achieve immortality and immortality.

Even among the immortals, it can be regarded as a powerful one.

On the other hand, Da Shui Ge, whose master, Xuanshui Sword Immortal, has the ultimate talent, but after cultivating all his life, he is still stuck at the peak of the Hedao realm.

Originally, in the latter's last words, Chen Feng thought that it was because of the Xuanshui Sword Immortal, because he had fought too many times with people in his early years, causing too many injuries in his body, that he had broken the immortal path, but now it seems that it is probably not only because of these reasons, but also because the exercises he practiced are not advanced.

But come to think of it, the exercises that can be cultivated to the realm of immortals, I'm afraid that the entire cultivation world will not have it, otherwise, so long has passed since the ancient era, but there is still not a single immortal, and even the spiritual void and the realm of harmony above the realm of refining gods are very rare, and I am afraid that it is also broken off from the inheritance, which has a great relationship.
