"I actually forgot there!" Han Fei was also annoyed, he didn't even expect this, that corridor was not short, the overall area was much larger than that in this cave mansion, if it was damaged, the possibility there was much greater.

"Take a break, it's tiring enough to check like this, if only you had divine sense" Han Fei then said, although he was also thinking about finding out that place as soon as possible at the moment, and then seeing the true secrets of this cave, but more than a day has passed since they entered the cave, and it is time to take a rest, who knows what will happen later, and it is easier to deal with it if he is in good condition.

"Well, it's okay" Su Mengli didn't care, cultivators would be able to stay without eating or sleeping for a long time after reaching the heartbeat period, but Han Fei proposed to rest and rest.

About a day has passed, and the sun and moon changes outside cannot be seen in the cave, and it has been illuminated by lighting strange objects, so I can't feel the specific time. Both of them have woken up from their breaks, their eyes full of energy and eagerness, it's time to discover the true secrets of this cave!

"Let's follow the previous method, although this corridor is long, it is very empty, and it should be checked quickly," Han Fei said.

"Well, I hope it won't disappoint us," Su Mengli also smiled back.

Then the two of them began to perceive carefully, although the perception is not as sensitive as the divine sense, but the effect is still good at close range, and they can basically detect the changes in the aura.

Originally, the aura in the cave was to flow outward all the time, but if there was a gap, the speed of the flow there would definitely be a little faster, because the aura inside was only driven by the flow outside, and the speed was of course much slower, and even some of it flowed back, which was lost in the replenishment cave, but the reflux was not very regular.

This time, Han Fei and the two of them were lucky, they only checked a small part of the corridor, and found the gap in a corner, when they came before, they both rushed inside, and they didn't notice that this place had been broken into a large piece, and even the crack still revealed a trace of formation light, and the aura slowly overflowed from that burst of light.

"This formation is really not simple, it is hidden in the rock wall, the person who arranged this formation is definitely a formation master, fortunately this is only a protective formation, there is no offense, otherwise it will be really difficult for us to enter here" Su Mengli sighed for a while, of course she came from the gate sect and had seen many formations, but there were very few who could arrange the formation like this.

"I don't know much about the formation, but since this formation is so powerful, and it's broken, it's estimated that the year is really a long time ago, I don't know what is hidden, don't be a treasure originally, but it can't withstand the passage of time, it's already corrupted, that's a pity"

Han Fei was still thinking about what he could meet here and get some good things, the Green Ox Sect was too poor in resources now, and it couldn't provide him with much at all, and in the future, if he wanted to save time and grow rapidly, the more resources the better.

"If there is really another cave hidden, what is worth hiding there must be very precious, and it will not be corrupted by time. "Su Mengli is actually still worried, it would be bad if there was something ominous hidden inside, they are actually very reckless now, she was born in the Eight Desolations, and some demon cultivators in the Eight Desolations know to kill after they are lost, such people are strong and difficult to kill, and they will generally be sealed.

"Let's see what the gap has become, if the damage is not serious, we probably won't be able to get in. ”

After saying that, Han Fei first cut the cracked layer of rock on the surface with a wind blade, but to Han Fei's surprise, the two long wind and waves with fifty percent power actually only cut a few traces, and this rock was not an ordinary rock!

"Han Fei, let me come, your realm is still low after all" Su Mengli saw that this rock wall was actually so hard, so she stopped Han Fei from continuing, it was better for her to come.

Su Mengli first wrapped the cracked rock wall with a layer of poisonous clouds, and used the true intention of poison corrosion to corrode the texture of the rock softly, and then used the explosion of poison to burst from the inside from small pieces, the way of poison is worthy of a special way, not only can poison creatures, but also has a miraculous effect on these dead things, the rock was slowly corroded into some small holes as soon as it came into contact with the poison, and then there was a subtle cracking sound inside, and the cuttings fell down.

Han Fei was very envious, his poisonous path had just started, if he wanted to reach Su Mengli's realm, if he didn't have an adventure, it was estimated that he would have more than ten years of talent, and this was still in view of Han Fei's special qualifications for Dao comprehension.

Half an hour later, all the cracked rocks were finally dropped by Su Mengli, and what they saw at this moment was a net-like formation traces, and the slightest array of light flowed, and they knew at a glance that it was very extraordinary, only in the middle was that a flag was broken into two, and it was there that the formation did not run smoothly and was relatively dim.

"It seems that it is this formation flag that is broken, this formation has a hole, as long as we take this flag away, this small piece of formation here should be invalid, and we will have a chance to enter"

Su Mengli said that she still knew more about the formation than Han Fei, she knew that generally powerful formations were composed of countless formation bases, and some great powers would refine a certain set of formation flags in advance to use as the formation base in order to make it easier and faster to arrange the formation.

"Is this the array flag, it's really amazing, a flag can make us helpless, if it weren't for its own breakage, it's really hard to say whether we can get in. ”

Han Fei looked at the formation flag with a curious expression, he didn't even know a lot about the formation method. Even if it was the array flag, it had only been mentioned in the mouths of Wang Xin and others before.

"A flag is not very effective, the array flags are all sets, each is connected to many other sides, plus one or more formations to preside, the whole formation seems so perfect and reliable, these I have only seen in the books in the sect, and I don't know much about the real composition of the formation" Su Mengli explained slightly, the formation is broad and profound, and those who are not with great perseverance and great talent dare not involve it.

"In the future, I will also go to the Zongmen Gongfa Pavilion to find books about the formation, the role of the formation is really not small, and it should be of great benefit to the future. Han Fei felt that the formation of this world was really a magical thing, and even those technological things on the earth could be derived with the formation, such as the transmission note, which had a similar function to a mobile phone.
