Six months later, Cheng Fei finally advanced to the fourth level of qi refining.

This promotion, I feel that it is much more difficult than advancing to the third level of qi refining. Cheng Fei knew that the fourth and seventh levels of qi refining were two important hurdles, and they were the existence of the small pass. Therefore, it took half a year of cultivation before I advanced to the fourth level.

After stabilizing his state, when he came to the location of the secret realm with Qing Feng, Cheng Fei found that there was actually the entrance to a cave in front of him.

Cheng Fei asked, "Inside?"

Qingfeng replied, "Well, inside, come with me." ”

Before entering the cave, Cheng Fei observed his surroundings.

The entrance of the cave faces east, and behind it is a small stone mountain, and the entrance of the cave is located at the bottom of a cliff several feet high. The surrounding vegetation is flourishing, and there is no trace of people. If you don't come here, it's hard to find out where the entrance is.

Entering the cave less than a few feet deep, the surroundings were already completely dark, and they could only rely on their divine sense to find their way.

Cheng Fei also found that this should be a natural cave, and the road under his feet is bumpy. Fortunately, the cave is high enough not to hit your head.

Cheng Fei trotted all the way behind Qing Feng, passing several forks in the road on the way. If it weren't for the fact that there was a legacy in front of him, and there was Qingfeng leading the way, normal people would not have gone so deep. No wonder this secret place has not been discovered.

After a few more forks in the road, it is estimated that after running into the cave for a few miles, Cheng Fei felt a faint strange feeling coming from front of him.

Cheng Fei's divine sense extended over, and he found that dozens of feet away, there was an existence similar to a portal. This should be the entrance to the real secret realm.

Standing in front of this portal-like existence, Cheng Fei observed carefully, and at the same time sighed in his heart: I didn't expect this kind of thing to exist in this world.

Gray, glowing with a faint light, it was obviously not a physical wall, but it was isolated from Cheng Fei's divine sense, and he couldn't see the situation behind the door.

At this time, Cheng Fei was a little nervous, after all, it was the first time to explore, and he had heard of it, but he had never seen it. But there was no time to hesitate, Qingfeng had already passed through the door, and Cheng Fei followed quickly.

After entering the secret realm, Cheng Fei's first reaction was dazzling!

It was like daytime, and Blue Feng was confronting the puppet at this time.

It may be that the previous entry of Qingfeng stimulated the mechanism of the secret realm, and at this time, the puppet was putting on a posture and preparing to attack Qingfeng.

Cheng Fei carefully observed the puppet, which was no different from life-size, and the production was slightly rough, without the slightest breath of life. Not only does it not have the breath of life, but even if it has the strength of the sixth layer of qi refining, it can't feel it at all, and it is obviously a model that can move.

Cheng Fei could clearly feel that with his entry, this puppet had shifted his attention from Qingfeng to himself. However, he gave up the intention of taking the initiative to attack and switched to defense.

Cheng Fei glanced at Qing Feng, who was also looking at him with curious eyes.

Cheng Fei asked, "The last time you came, was it also this defensive posture?"

Blue Feng replied, "No! The last time I came in, it rushed over. ”

"Hmm!"

Cheng Fei responded and began to take the opportunity to observe the surrounding environment.

I saw that there was an area of more than 100 zhang square, with obvious traces of artificial excavation. Obviously, this is no longer a natural extension of the cave outside, but more like a small courtyard.

Around this small courtyard, there is a circle of gardens that are about a foot wide against the four walls, and various spiritual materials grow in it. Cheng Fei took a cursory look, and few of the plants he knew should be spiritual materials above the third grade, which made Cheng Fei secretly happy.

But just the few spiritual materials he knew, but Cheng Fei's eyes were shining, and they were spiritual materials that were more than a few hundred years old. In this way, in this room, in the small garden surrounded by the surrounding walls, aren't all those spiritual materials hundreds of years old?

Sent !!

On the left side of the opposite wall, there is a passage that leads to nowhere.

At the entrance to the passage, there stood an armory rack on which were placed two swords and a sword. Cheng Fei knew at a glance that it was not ordinary. I saw that the three weapons were finely made, simple in style, and dull in luster, and at a glance I knew that they were by no means mundane things.

After looking at it, Cheng Fei said, "Don't do it first, I'll meet him." ”

After speaking, Cheng Fei took a few steps forward, then hugged his fist at the puppet opposite, and then bullied forward.

This time, Cheng Fei did not use weapons and fought against the puppets empty-handed. First, the puppet did not hold a weapon in his hand, and second, Cheng Fei did not want to cut the puppet.

In this fight, Cheng Fei found that the puppet in front of him had the strength and speed of the sixth layer of qi refining, but his moves were rigid and he didn't know how to be flexible. The human at the peak of the sixth layer of qi refining was enough to defeat him.

After fighting for a while, Cheng Fei found that there was really nothing new, so he threw off the puppet and went straight to the stone platform, holding the booklet placed on it in his hand.

It's strange to say that as Cheng Fei picked up the booklet, the puppet actually stopped attacking, as if Cheng Fei had passed the test.

Cheng Fei cautiously returned to Qingfeng's side and read the booklet.

I saw that it read: "If you can get this booklet, you have passed the test." There are no heavy weapons here, just some gadgets left with destined people. Here are a few small spells that are better than nothing!"

Cheng Fei looked carefully and found that there were several small spells recorded at the back of the booklet, namely: Addiction Qi Technique and Five Elements Spiritual Technique!

Addiction Formula: You can hide your own breath, so that the other party can't see your true strength. But the pamphlet also mentions that it's just a gadget. If you encounter a strong person who crosses a large level, this technique is useless.

For example, if you are still in the Qi refining period, no matter how addicted you are, your true strength will not escape the eyes of the foundation building powerhouse.

Five Elements Spiritual Arts: Teaches how to use one's spiritual power to control the five elements of metal, wood, water, fire, and earth around the body. Cast small spells such as the Five Elements Escape Technique, the Rain, the Dam of Soil, and the Flowering of Dead Trees.

These little spells are all gadgets that are not worth mentioning in the Immortal Gate. But in the mortal world, it is the embodiment of the difference between humans and immortals. And what Cheng Fei lacks most now is these small spells.

Cheng Fei is also looking forward to it sometimes: when he finishes the seventh layer of qi refining, will he have the strength of others in the foundation building period?

After explaining the record of this booklet to Qing Feng, Cheng Fei first collected the spiritual materials around him. Put away the three artifacts again. Especially the spirit knife, Cheng Fei couldn't put it down.

The difference between a spiritual weapon and a mortal weapon is its tenacity and its ability to transmit spiritual power as an extension of the arm. An ordinary weapon in the mortal world, Cheng Fei can easily break it, but these three spiritual weapons, Cheng Fei keeps breaking no matter what.

Next, Cheng Fei did not continue to explore along the passage, but began to practice several small spells recorded in the booklet.

Patience is a virtue!

Who knows what will happen when you enter the next room along that passage? Although these small spells have no actual combat effect, "Addiction Qi Recipe" is a sharp weapon for Cheng Fei to play a pig and eat a tiger in the future, and Cheng Fei simply loves this little spell to death.

These little spells were very simple, Cheng Fei didn't take an hour to master them, and then it took another two or three hours to become proficient, until he mastered them, and then walked towards the passage.

Qing Feng pouted behind Cheng Fei, his contempt was extremely strong!

In Qingfeng's view, only strong strength scares off opponents, why hide their own strength?
