(PS: I just got up, I wrote more than one chapter before going to bed yesterday, I try to write two chapters before going to bed today, and strive to update two chapters tomorrow, rest assured, I will do my best to keep changing, starting with this book, keep changing, I will do my best to do it.) ）

When the two of them searched for various clues about this ruin, Yun Qingqing deliberately put on a proud and disgusted expression, but she took the trouble to tell Hao Qi in detail what she knew in her current memory.

Knowledge is priceless, especially the knowledge that involves the truth of history is even more priceless, because compared with most other knowledge, the knowledge of the truth of history can be transformed into great wealth or huge power, at this point, it is incomparable to the vast majority of other knowledge, the only thing that can be compared with it is the knowledge that involves martial arts and the progress of strength, in other words, if someone tells you the knowledge of the truth of history in detail, this is almost comparable to the great virtue of your master。

Hao Qi knew it and was grateful to Yun Qingqing, but he sighed again in his heart...... It's really not good to help her out.

"The primeval miracle era, the ancient internal force civilization era, many people who study the history of these two eras may take it for granted that the characteristics of these two eras are that the primeval miracle era is only specialized in science and technology, specializing in large-scale creations, miracle creations, involving the study of space and time, while the ancient internal force civilization era is focused on the body, focusing on internal force and internal qi, focusing on martial arts and self-evolution, in fact, this is not the case. Yun Qingqing said to Hao Qi while rummaging through some rocks and traces on the ground.

"In the primeval miracle era, from many existing records and proofs, it can be shown that although they could not absorb the free energy of heaven and earth, so as to build an energy circulation system in the body and have internal force, but they relied on the developed technology as if a miracle, almost all the people generally strengthened their bodies and life span, there is evidence that the ordinary people in the primeval era had a lifespan of almost three hundred to five hundred years old, and almost everyone in the primeval era, especially the military personnel, was a quasi-internal force realm of the body. ”

"And the era of the primeval internal force civilization, inherited from the ruins of the primeval miracle era, they have a large number of primeval creations, as well as the remnants of the primeval era, although the level of civilization has dropped greatly because of the great collapse, especially the most high-end technology involving space and time is almost completely lost, but the scientific and technological civilization of the ancient internal force civilization era is simply more than ten streets away from us, and the ancient internal force civilization era is also a complete human country, the political structure is tens of thousands of times better than the current seven seas, the welfare of the whole people, the whole people practice martial arts, and has developed a completely different scientific and technological progress route from the primeval miracle era, that is, the internal force civilization technology, the creation of ancient times, most of which have a relationship with the internal force and internal qi in the human body. ”

Speaking of this, Yun Qingqing showed the giant spear in her hand to Hao Qi, and said at the same time: "Although this weapon of mine is forged with the military internal force alloy of the primeval era, its forging technology actually comes from the ancient era of internal force civilization, and it uses a system called 'Dream', and my elders ...... It is also a fusion of his heart in this weapon, this is a super internal force weapon that exceeds the conventional weapons of the ancient internal force civilization era, but the general principle is the same, the ancient internal force civilization era, at that time human beings for internal force, internal qi, god coverage, true appearance, heart phase, god phase have a very detailed study, and the science and technology at that time also moved towards the road of the combination of internal force and machinery, in which weapons, armor, and related combat creations are the pinnacle of this combination, of course, such creations, whether it is weapons, armor, or robot-like defensive puppets and the like, are all graded。 ”

"My weapon is called 'Sweet Dream', and my brother's steel needle weapon is called ' Nightmare', this is a weapon that can touch the heart as long as it completely erupts, and is fully controlled, according to the information in my memory, this kind of super internal force weapon is divided into four grades, the weakest grade is to allow the user to exert the strength of the internal force realm, even ordinary people can do this, it can be called an internal force product, and the upper level of the super internal force weapon, can allow the user to exert the strength of the internal qi realm, and still ordinary people can do this, but they need to pay some price, such as lifespan, vitality or something, but compared to the huge strength it can play, this cost can be said to be minimal, this is the second product, that is, the internal gas product. ”

"And then up, it's the dream I have, the nightmare that my brother has, this level of super internal force weapons, when the full force bursts, can exert the strength of the heart phase, this level of super internal force weapons can be called the heart phase product, and the legend, in order to correspond to the creation of the seven final battle weapons at the end of the primeval era, blue, red, pitch black, pure white, gold clear, ancestral green, and empty green, the ancient internal force civilization era spent a huge price, and a total of seven strongest super internal force weapons were forged, these seven super internal force weapons are once completely broken out and used, which can make people exert the strength of the god phase, this is the final grade, which can be called the god phase product。 ”

When he said this, Yun Qingqing said to Hao Qi seriously: " That's why I said, if we really find this ancient internal force civilization ruins, if we are lucky, we can leave this underground three-layer world immediately, or safely and quickly, according to the display in my memory, in the ancient internal force civilization era, a large number of supply stations, transfer stations, fortresses and the like were built in the underground three-layer world, among which the supply station generally has a battle puppet of the inner qi realm, and the transfer station has ten battle puppets, but once it reaches the fortress, then it has at least more than two hundred internal qi realm strength battle puppets, which is the reason and confidence that the ancient times can use the underground three-layer world as a harvesting ground, as a fishing ground, and as a pastureJudging from the signs here, this layer of resistance is likely to be a fortress-level relic, we don't need so much, only one or two internal qi realm battle puppets can still operate, then our safety factor will be greatly improved, if there are more than three, or even more than five battle puppets, then we can basically walk sideways, even tyrannical creatures are not afraid, do you think that if we can investigate wantonly, go anywhere at will to find an upward passage, as long as we are careful not to touch those weird space areas, we are still far from returning to the surface world？”

Hao Qi nodded stunned, to be honest, he was a little frightened, although he had been mentally prepared for the ancient internal force civilization era, but when he heard the strength of this era, he was still a little frightened, so he immediately asked: "By the way, according to the legends circulating outside now, in the ancient internal force civilization era, there was a so-called internal force walking all over the ground, and the internal qi was not as good as a dog, and only the true qi could shake it, that era...... Is there really so many internal qi and true qi realm powerhouses?"

Yun Qingqing laughed crisply, she looked at Hao Qi and said, "You are so stupid, is it so easy to believe those rumors?" These are just rumors, if you really have to say it, the first two sentences are also correct, because of the super internal force weapons, as well as the development of internal force machinery combined with science and technology, the internal force realm and the internal qi realm are indeed exaggerated in that era, and there is even a legend that there was an army of more than 3,000 people in that era, which is an army composed of soldiers with a god coverage rate of 30 percent, but the god coverage rate of 50 percent is a hurdle, and then, the god coverage rate should reach 90 percent, and the comprehension of the god is a huge gap between heaven and earth, even in the ancient era of internal force civilization, the god phase strong people who exist at the same time are no more than ten people, as for the True Qi Realm above this......"

Yun Qingqing shook her head, although she didn't continue, but the meaning was already very clear, and when Hao Qi was about to continue to ask something, Yun Qingqing suddenly squatted down and began to dig underground with her hands, and in a moment she dug a deep pit about three or four meters deep, and the outline of a thing was revealed from below, it was a huge robot arm, the arm alone was the size of an adult man, but there was only an arm, and the other bodies of the robot had disappeared.

Yun Qingqing looked at this arm for a long time, and dug many places around this arm, Hao Qi didn't know what she was judging it on, but most of the places she excavated had various relics fragments, or various traces of battle, and after a long time, before Du Block was about to go back to the temporary camp, Yun Qingqing finally had a new judgment, and this judgment was......

"The ruins are most likely underground...... Beneath the valley!" (To be continued.) )
