It seems that the science and technology of the "Pangu people" at the beginning were far more advanced than today's human society. Fu Chenxue secretly made up her mind, it was not easy to come here, and she had to get something useful to go back.

As if seeing through Fu Chenxue's thoughts, he smiled and said, "Great Elder, you'd better not bring the things here back, not to mention causing trouble when the time comes, it may also cause a war in the outside world." Because a lot of the things here are shocking to the outside world, and if they fall into the hands of careerists, it will be a great disaster. The 'Battle of the Hundred Tribes' was a living example, so after the catastrophe, the 'Pangu Clan' moved here, and the 'Senate' sealed up a lot of things, and for tens of thousands of years, the 'Pangu Clan' had wars, but it would not be destroyed, and it has continued to this day, this is the truth! ”

Fu Chenxue felt that there was some truth in Pan Huan's words, there was no weapon to destroy the mière, the civilization of the "Pangu tribe" had regressed tens of thousands of years, in the era of cold weapons, even if there was a large-scale war, how many people could die? Moreover, there is also the "Council of Elders", who have advanced weapons and civilizations, and are almost god-like beings, who can control the process of war at any time. But then again, just because you are afraid of ruining miè and stop developing, isn't it because you choke on food? The development of human society has always been forward, and who has the power to stop the progress of civilization?

Fu Chenxue said: "The development of science and technology in the outside world is advancing rapidly, as early as a few decades ago, human beings have flown into space and landed on the moon, some things are not given to them, they can also get them, I just want to advance this result." Of course, I will have a choice, I will not leak all the advanced technology, and I will not give it to all countries. As you said, some things are too far ahead of their time to cause chaos. ”

Pan Yan said: "You can decide for yourself, it's just that we don't want people outside to be in danger of coming here because they have mastered advanced technology, this is the bottom line." At this point, he looked at the other people, saw that they did not object, and then said, "Before we go, let's take you to a place!" ”

Fu Chenxue was puzzled: "What place?" ”

Pan Hu said mysteriously: "Don't worry first, you'll know when you arrive!" ”

A few people walked out of the hall and flew into the air with the "six-pointed star", Fu Chenxue only heard the sound of the wind in his ears, and the mountains and reckless forests flickered under his feet. In the past three years, he has mainly devoted his energy to cultivating "Pangu Jue", and he has never piloted this kind of high-speed aircraft, and the first time he experienced the feeling of flying at high speed, it was really enjoyable!

I don't know how long it took for them to land in a tall mountain range. Jumping off the "six-pointed star", Fu Chenxue saw that there was a square full of ancient atmosphere in front of her, and the square was so big that it seemed to be boundless. Behind the square are the rolling mountains, which disappear into the rolling sea of clouds from the mountainside, and I don't know how high they are. Pan Yi led a few people through the square, walked to a big mountain, and with a wave of his hand, a huge cave suddenly appeared on the slope of the mountain originally covered with black sandstone, from the ground to the top of the cave, at least three hundred meters, and the door of the cave was closed.

Seeing Fu Chenxue's doubts, Pan Yi explained: "In order to prevent the secret from leaking, there are special enchantments outside the cave doors, and it is impossible for people who are weaker than us to open the enchantments and discover these caves. ”

"These caves?" Fu Chenxue asked in surprise, "You mean there is more than one cave like this?" ”

Pan Yi smiled slightly: "Of course there is more than one!" There are a thousand and one caves like this, and this scale is less than one-thousandth of the time of the 'Hundred Clans War'! ”

"A thousand and one?" Fu Chenxue gasped, what kind of scale is that? Isn't it bigger than the air bases of all the countries outside combined?

Pan Yi twisted the ring, and suddenly a thing similar to a computer keyboard appeared in front of him, he used his fingers to "snap" on it for a while, probably to enter the password, the huge metal door slowly parted to both sides, this kind of door is made of metal I don't know what kind of metal, up to five meters thick, weighing about 30,000 tons. Fu Chenxue really couldn't guess what kind of machinery was needed to control this kind of door. To Fu Chenxue's surprise, there are seven doors like yours, each of which requires special instructions to be entered, and the number of fingerprints, pupils, hair, and blood can only be passed. Entering the seventh gate, a vast world appeared in front of Fu Chenxue, the lights were bright, as bright as day, the length of the cave was at least fifty kilometers, and the width was also more than ten kilometers, as for the height, almost the entire mountain was hollowed out. The light on the top of the cave is dense like the stars in the sky, not a dazzling incandescent lamp, but a "forever light lamp" that blends with the cave wall. The light is extremely soft, flowing down like water, like a dream. What's even more fantastic is that the cave is full of all kinds of flying machines, including the giant "Galaxy Battleship", as well as small and exquisite individual spaceships, saucer-shaped, round, dropdrop-shaped, streamlined, and six-pointed star-shaped ...... There are all kinds of flying machines that can't even be named. As for weapons, space "electromagnetic cannons" are the most common, and high-powered kinetic weapons, energy weapons and laser weapons can be found everywhere. There are many weapons that, at the current rate of development of human science and technology, will not appear until at least a thousand years later.

After taking the rail car to visit the cave for a week, Fu Chenxue took a long breath, a cave has such a scale, how magnificent is the sum of the things in a thousand and one caves? Fortunately, the outside environment is no longer suitable for the survival of the "Pangu clan", otherwise with these warships and weapons alone, the outside world will not know how many times it will be destroyed.

Fu Chenxue asked, "It's always been like this here?" ”

Panyi said: "Since we came here, it has always been like this!" ”

Fu Chenxue looked up at the roof of the cave and asked, "Where did the electricity come from?" ”

Pan Yi smiled: "Guess! ”

Fu Chenxue thought for a while and said: "You can't use hydropower, the underground thermal energy is abundant, but its stability is not good enough, I guess it's nuclear energy!" ”

Pan laughed: "You guessed right! Only nuclear power can provide near-eternal electricity. The nuclear power plant of the 'Pangea' does not use radioactive materials on the earth, but the 'antimatter' brought from planet R, which has no radiation and is a relatively clean energy source! ”

"Antimatter?" Fu Chenxue was shocked, it is said that the energy of this substance is terrifying, only a few tenths of a gram can create a nuclear explosion equivalent to a million-ton equivalent, and now scientists from all over the world are still arguing about its existence or not, but I did not expect that the "Pangu tribe" could use it to generate electricity tens of millions of years ago
