The name of "Qi Refiner" was pondered by Gu Yi himself, and Fei Yi (Ben Yi) originally planned to directly call them "Cultivators", but they were despised by Shuguang, and mockingly told Ben Yi to look at the memories in his head when he had time.

Obviously, everyone shares the same brain, but they never look at the various materials he sorted out, just waiting for him to sort it out, the forging body directly uses bioelectric cells to manipulate the program, control the automatic operation of the body, and he has to practice it first and then directly reproduce the memory into their consciousness.

Gu Yi and Fu Yi didn't dare to say anything about Shuguang's words, and secretly muttered to themselves, isn't this a capable person who works hard?

It's right for everyone to "share" a brain, but the problem is that the madman Shuguang didn't know how much information he stuffed into his brain, and he didn't install a search engine.

Besides, someone does it for you, can you be lazy for Mao or not? What else do their brothers and sisters have to divide between you, me and him.

According to Shuguang's statement, although the cultivators in the Xianxia novels they had read before felt very similar, if they studied it carefully, they actually belonged to a different system at all, and if they had to say it, the title of "Qi Refiner" could barely match it.

After all, no matter what they understood as "Qi Refiners", the martial cultivators of the Great Desolate World Realm were indeed based on cultivating Yuan Qi and Yuan Power.

Different from the level of strength of cultivators such as foundation building and golden pills, the division of strength of "qi refiners" such as sorcerer cultivators is actually based on the number of simple cycles of running qi refining techniques.

Those who can carry out a cycle of vitality in the body are "L-ring Qi Refiners", and those who can run two cycles are "Ring Qi Refiners", and when they reach the 3 rings, it is a small level, and after crossing over, the amount of Yuan Qi will get a small step-like jump, and the U ring and 9 rings are a small level...... Every multiple of 39, you will get a step-by-step boost.

The "Anonymous" who just hung up, even if he improves one ring in three years, it is estimated that he is a little master of qi refining in recent years, and he has not had time to apply what he has learned, so he was so tragically stoned to death by Fei Yi.

Gu Yi rubbed his chin and said thoughtfully, "The Six-Ring Qi Refiner is so crispy?

Fu Yi was stunned for a moment, blinked and said: "I am now the strength of the ontology, I remember that the ontology has already cultivated the guidance and refining qi technique in the first three volumes of the "True Heaven Ginseng Body Spiritual Cultivation Deed" to the thirty-six rings, right? 36 divided by 10 equals. U multiplied by 3 equals 10. 8 ̈ barely counts the eleventh ring, right?"

"That's not how you count, right? We mainly take the refining route, you only count the vitality content, right?"

Gu Yi felt as if something was wrong, and frowned: "Eh, it's not right, our vitality content can be compared to ordinary qi refiners, how much vitality can we absorb in one cycle, and how long is our cycle?"

The two pondered for a long time, but they didn't understand it, so they simply didn't think about this headache, and when the time came, they would find someone to single-handedly pick it up, and they would probably know how many rings of Qi Refiner their strength was equivalent to.

"They've been in for a long time, haven't they?"

Fei Yi shouted loudly, and took the lead in a flash into the huge cave, Gu Yi also followed in, but as soon as they entered, the two of them were dumbfounded, in this cave, there are more than a dozen branch caves at the entrance alone, and the other party has entered the cave so long before them, so tell them to go there to find someone?

If they were the traditional qi refiners of the Great Wilderness World, they might be able to master some techniques, such as tracking the traces of vitality left by each other, but although the two of them had also cultivated the qi refining technique, they couldn't use a single technique.

Fortunately, they also have other ways to track without magic, Gu Yi waved his hand and took out a silver metal box about one meter high, octagonal cylindrical, and after pressing the open button above, he heard an exhaust sound of "snort", dozens of small windows were opened on the octagonal cylindrical metal box, and a subtle and dense buzzing sound was heard, and a miniature flying device with the length and thickness of a thumb flew out of it.

These micro-flying machines, which look like bullets with dragonfly wings, are named "Hummingbird Detectors" by Dawn and were originally used for resource exploration, but a temporary cameo appearance as an environmental detector should not be a big problem.

In an octagonal cylindrical metal box, there were thousands of hummingbird detectors like this, and after being activated, they buzzed and vibrated their wings like a swarm of bees, hovering above them, and then under Gu Yi's order, they divided into more than a dozen "bee swarms" and poured into the cave branches, and then began to continuously release ultrasound waves, scanning the terrain and environment.

The vision of the two people who stopped at the entrance of the cave flashed, and a map of the underground cave began to spread in their eyes at a rapid speed, and then a virtual topographic map was drawn.

Soon, a large flock of hummingbird detectors began to divert and divert in front of the cave branches, and if they hit a dead end or a cave that the human body could not pass, they immediately turned back to find a new path.

It didn't take much effort for the hummingbird detector to find the traces of those who had entered the Zuli Cave first, and the two nodded, activated the bionic mimic flight mode, and scurried out.

The terrain of Zuli Cave is a typical karst cave terrain, although it is covered with a large number of stalactites and stalagmites, but because the space is quite huge, there is no need to worry about flying too fast and hitting it headlong.

In addition, the hummingbird detector has clearly detected the route conditions along the way, and the built-in core of the 丨Huang-丨 type will not only carry out automatic navigation, obstacle warning, and even correct the flight attitude and speed of the two.

Don't say that the two of them can see clearly in this dark environment, even if they close their eyes and fly at full speed, they probably won't hit the stone, the feather blade behind them either vibrates, or slaps, and sprays from time to time, the two are flexible like fleas, jumping through the cave quickly, and soon caught up with the target, falling far behind each other.

Behind the Li team, there were more than a dozen waves of people, each looking like they were ghosts, but they seemed to have reached a tacit understanding and did not attack each other, even if they met together, they were just vigilant against each other, hanging far behind the Li team and moving forward silently.

The Li team had apparently noticed that someone was following them, but strangely, they didn't pay attention to those people, they just buried their heads in the road, and the group kept going deeper into the ground.

The first box of hummingbird detectors released by Gu Yi had already flown away, and there were no two together, so he had to take out a "beehive" and release it every time he advanced a certain distance to replenish the diluted hummingbird colony.

After releasing more than 20 boxes of hummingbirds, the Li team in front finally slowed down, and it seemed that they were about to arrive at the location, and at this time, the group of hummingbirds released by Gu Yi still did not detect all the cave maps, which shows how complicated the terrain of this Zuli cave is.

It's thanks to them coming in and replacing them with ordinary people, even if you give him a map, it is estimated that he will be starved to death because he gets lost in this dark underground world.

Gu Yi and Fei Yi flew in all the way behind the family, and were shocked by this huge and complex underground world, the underground cave is not unusual, what is strange is that this karst cave is huge.

According to the data shown by 丨Huang-丨Type丨, they have gone seven or eight kilometers deep vertically underground, and the length of the journey is hundreds of kilometers long, although many places will pass through quite narrow caves, but in general, each cave is very wide.

The most amazing thing is that these underground caves are very solid, and no collapse has been found, whether it is the stalactites hanging from above or the stalagmites emerging from the ground, they are all very intact and have no signs of crumbling.

In particular, some of the super-large underground caves passed by on the road are large enough to accommodate the next small and medium-sized city, and if this place can be developed, it can be directly used as an underground city.

Thinking of the "underground city" under the mountain range that is also being developed in Yanhuang China, Gu Yi wonders if the underground of this great wilderness is completely empty, and there are so many underground cavities there.

With the continuous release of information from hummingbirds, a large number of underground plants and biological groups have been found in this Zuli cave, and even wide underground rivers and underground lakes have been discovered, and all kinds of strange creatures live in this dark world.

Many underground creatures are extremely aggressive, and many of the hummingbirds he released were damaged by the attacks of the underground creatures.

The Nari team barely stopped along the way, and there didn't seem to be any underground creatures on their route.

According to the intelligence, these Li people should have never entered here, and like them, they only recently discovered the Zuli Cave and organized personnel to enter it for the first time.

However, they seem to be very familiar with this underground world, if it is not to say, the Li people really have any inheritance, then it means that they should have something to guide the way in their hands

Just when Gu Yi guessed that he was about to reach the place, the dozens of Li people in front of him suddenly stopped in front of a huge hole, but the people who followed them began to speed up.

Gu Yi and Fu Yi glanced at each other, and were about to speed up to follow, when they suddenly heard a deafening strange roar, coming from the depths of the earth, a huge sound wave, and even produced a terrible sound roar in the cave, forming a violent wind, whistling and sweeping over
