(PS: Woke up late...... I didn't wake up until about 4:50, sorry, sorry, the first shift, and the second shift in a while. ）

The two explored in different directions, with the valley as the center, and the two explored in the direction of its left and right, each agreeing to return here after twelve hours of exploration.

Hao Qi chose a direction, and then began to explore over there, since he fell into this underground world, he has been in this underground world for almost a month and a half...... The delay here is not counted, because there is no memory, so the actual time is about a month and a half, nearly two months or so.

During this period, Hao Qi also gradually began to familiarize himself with everything in the underground three-layer world, as well as learn all the experience, information, etc. about the underground three-layer world from Yun Qingqing, after all, this is an attempt, an attempt to travel in the underground three-layer world, although the purpose is only to escape back to the surface world, but with this experience, he will lead the entire team into the underground three-layer world to explore in the future, so he can't help but be careless.

Now, more than a month later, Hao Qi knows some general information about the underground world, for example, the mad-level creatures here don't need to eat food, but most of their food is each other's level creatures, either the fierce creature race, or other mad-level creatures as food, and the surface world is basically impossible to have such a situation, even if two mad-level creatures meet, they generally retreat to avoid fighting with each other, but this is equivalent to the norm in the underground world.

According to Yun Qingqing, there is a very special environment or rules in the three layers of the underground, here, it is very easy for non-human creatures to improve their level, basically it is difficult to find ordinary creatures, basically the worst are fierce creatures, and then mad creatures, in this case, it has become the norm for level creatures to hunt each other, and once a large number of non-level creatures appear, a bloody feast will be formed, similar to what they have experienced before, a large number of mad creatures gather and begin to devour a large amount of food from the hard, and at the same time, the gathering of a large number of mad creatures will lead to the emergence of violent creatures, which will lead to the mass extinction of an area。

and as a non-rank creature...... For example, Hao Qi belongs to a non-level creature, even if he is in the internal force realm, but before the real fight, he is food for the vast majority of creatures in the underground world, so once he is discovered, it is likely to cause a commotion, which is also one of the lessons he has learned in the past month or so, hide himself as much as possible, in the shadows, hold his breath, and act softly, once discovered, either escape away immediately, or kill the enemy as quickly as possible, this is one of the ways for human beings to survive in the three layers of the underground world。

According to Yun Qingqing, in the era of the ancient internal force civilization, human beings once established large-scale fortress stations in the underground three-layer world, and for a long time, the inner qi realm led the team to clean up the hierarchical creatures of the three-layer underground world, and an industrial chain had been formed at that time, similar to the current human fishing for the ocean, perhaps for the human beings at that time, the underground three-layer world was a land of wealth, but for the humans of this era, the underground three-layer world was similar to hell.

Hao Qi explored very carefully, but his strength was already very strong, so although he was exploring very carefully, the twelve hours of exploration and return also allowed him to explore a huge area around him, in this area, he found several places where he could climb over the mountain canyon in front of him, but most of the canyons are extremely dangerous, because this kind of only has one entrance and exit, and the interior is a semi-closed environment, which is very suitable for level creatures to use it as a nest, especially tyrannical creatures, even in this underground three-layer world, tyranny-level creatures are also sleeping most of the time, and places like this kind of canyon are simply natural beds when they sleepIn these canyons that Hao Qi explored, he confirmed that there were at least two tyrannical creatures, or three ...... Who knows, anyway, he didn't enter it, but he already felt extremely dangerous outside the canyon, and then immediately retreated, even if it was not a tyrannical creature, it must be as dangerous as the existence of a tyrannical creature, he really couldn't take the risk.

And in this canyon, there are two canyons that he does not dare to enter, there is no threat in these two canyons, as if there is nothing in them, this is too abnormal, it is simply impossible, such an extreme abnormality makes him dare not enter this canyon at all, it is likely to be a trap.

When he returned to the camp and met with Yun Qingqing, the two of them exchanged their itineraries with each other, and then the two of them were speechless and found that there was basically no safe area in this canyon and the underground mountain range, compared to the plain, this kind of isolated area of one canyon and one canyon was like a well-built apartment building, with mountains isolated from each other, and dangers lurked in each other, either violent creatures, or rare mad-level creatures, or unknown dangers, all in all, there was no safe area in this area。

"So...... Are we going to turn back now, or turn back, or turn back......" Hao Qi was speechless and looked at the animal skin that Yun Qingqing recorded in the nearby terrain, and almost all of it was painted with skulls.

Yun Qingqing hesitated for a moment, shook his head and said: "We have been walking downstream for almost two months, and the previous drifting distance is even longer, if we go back upstream, we estimate that it will take more than two months or even three months, you must know that this is the third layer of the underground world, every day we stay, our danger will rise, this danger...... In short, we'd better get out of the three layers of the underground world within a year, or we'll probably never be able to get out. ”

Hao Qi didn't understand a little, but it was indeed a very important thing to get out of the underground world, he thought for a while and said: "But it's not a way for us to be trapped here all the time, either we can get out of this underground river, find a direction and go there, or go back upstream, even if it takes more than two months, it's better than being trapped here all the time." ”

Yun Qingqing also hesitated, and she said after a long time: "It's not impossible to break away from the underground river and head around, but without the reference, we are likely to get lost in this endless underground three-layer world and return to the upper reaches...... I don't need to mention this again, do you remember that violent flame lizard? You knocked one of its eyes out and blinded it, even if it was a tyrannical creature, it is estimated that it is difficult for this high-precision organ to heal completely, and even after healing, its eyesight will be extremely reduced, so it hates us, the intelligence of the tyrannical creature is almost not lost to humans, if it is a super grudgeful tyrant-level creature, it is even possible to track us and swear to kill us, as long as we return to that semi-lava area, then it will be desperate to hunt us down, so do you still want to go back?"

Hao Qi only had a wry smile left, and the two of them couldn't do it at the moment, so they could only choose to continue to explore, explore as much of the area on both sides of the underground river as possible, and then decide whether to leave or stay when the time came.

Far up the river unbeknownst to the two men, a huge salamander was confronting another tyrannical creature as it was coming down the river and invading the tyrannical creature's territory...... (To be continued.) )
