After most of the day's journey, when everyone was tired, the muddy ground under their feet completely disappeared, the swamp forest behind them gradually blurred, and the adventure of several days of hot and humid swamp land came to an end. The afterglow of the sunset is sparkling and reflected on the side of the mountain road, everyone's mood is also relaxed and happy, the dark clouds of death that have shrouded everyone's hearts in recent times have also dissipated with the faint sunshine, the bluestone road paved with moss under the feet, the traces of artificial casting and the witness of the existence of civilization are becoming more and more obvious, and the ancient city sealed in the sea of history seems to be quietly opening the gate to them, waving their hands. The open area on both sides is a mountain peak with towering clouds at the forefront, and it is refreshing to look at.

They quietly watched this beautiful scene, immersed in the natural scene that was like a fairyland on earth.

Wu Min has a strong sense of purpose, and the scenery is not eye-catching, and he began to prepare for surveying, mapping and analysis in the combination of instruments and equipment, and analyze the structure of this mountain in combination with the topographic map stored in the computer. The mountain peak in front of you is about 3,000 miles above sea level, and there are faint clouds and mist in the middle, and you can even see small dots in and out of the clouds.

Only Wu Min can manipulate the precise instrument control, and the computer display screen is connected to the surveying and mapping equipment, and the radar and sonar mapping information is transmitted back in a short time and is phased on the screen. The topography of the mountains in front of you is presented at a glance in front of a small screen, and the three-dimensional graphics are flipped with the rotation of Wu Min's mouse, the mountains and rivers are far more magnificent than the visual one, and the endless mountains are constructed into a crater, which resembles a volcanic crater, and the area surrounded by the middle is the ultimate goal of the trip.

Wu Min pointed to the mountain peaks in the distance, which were steep and upright at an angle of about 70 degrees, which were part of the ring mountain range. She told everyone that the next task was to climb over the mountain, and then go straight down from the other side of the mountain, and the results of the measurements were consistent with the map structure they had before, and some of the mountain's geography had changed due to age, but it was generally the same.

"You're saying the ancient city is right behind this mountain?" Han Qingxin frowned and said, it is not easy to climb over this mountain.

"Look." Wu Min pulled the results of the screen mapping closer to the analysis, the three-dimensional map crossed the mountain range after a square city line in front of the eyes, according to the proportion of the mountain, the city is built in the mountains and rivers, the radius is dozens of miles, the three-dimensional line shows the skeleton of a city, the harmony of the angle of the building water chestnut all convey the amazing craftsmanship of this ancient city.

Jiang Erye was so excited that he almost didn't know how to express his mood at this time, his cloudy eyes bloomed with the brilliance of life in an instant, and he repeated countless times in his mouth: "The yellow sand is thousand, the sky is full of soil, the frost is like dust, the clouds and mist are ethereal, and the sky is peerless." It is rumored that the craftsmen who built this ancient city took 800 years to complete, and even the bricks and stones used to build the city wall weighed more than 100 tons, and the error of the north-south and east-west lines was not more than 1 centimeter. ”

Zhu Beichen couldn't hide his joy, the ancient books that he had been looking for for more than half a year might be hidden in the ancient city behind the mountain peak, and with the hope of life, he couldn't wait to grow a bunch of wings to cross the sky and reach the other end of the mountain.

The most exciting thing is the fat man, the ancient city is of great significance to him, of course, there is no lack of mountains of rare treasures in such magnificent ancient buildings, and even more powerful visual effects than the golden and silver piles seen in the tomb of the sun, but everything is like dust and dung compared to that ancient book.

The information of the ancient city is more detailed than the Jiang family, an ancient family, and only he knows what clues led Jiang Er Ye to find here. The emotions of the seven rooms did not fluctuate at all, but the worries in the eyes of the mountains and rivers and the sea of clouds became more solemn: "The yellow sand is a thousand jun, the sky is full of soil, and the ancient city buried in the sand literally means the ancient city in the yellow sand, isn't it?" "Don't say yellow sand, the climate and environment here are good, the vision is wide and clear, and there is no smell of dust in the air, what does Jiang Erye's words mean?

"It's ridiculous, the ancients played with words the most, does this kind of word play still need to be explained? When you arrive in the ancient city and see the extraordinary architecture of this building, you will understand what is the amazing skill of raising sand and dust, and the ingenuity of the craftsman. Second Master Jiang didn't even bother to explain, his eyes seemed to be able to penetrate the mountain peaks that were barrierd, and peek into the world-famous city thousands of years ago.

Seven stared at the computer in Wu Min's hand, the map stored in the computer was hand-drawn through memory, and as for other information, it is believed that it is also stored in the computer, and the straight lines mark the bluestone ancient road under the foot now, leading to the foot of the mountain.

Wu Min has been repeatedly calculating the geographical information such as the inclination angle of the mountain, and his brows are indeed wrinkled more and more, so that he twists into a Sichuan character: "Radioactive materials, the mountain peaks in front of them have extremely strong radioactive materials." ”

Radiation is an invisible substance, and without high-end electronic devices waiting to be discovered, the consequences can be irreparable. The momentary joy was all replaced by astonishment, and everyone stared at Wu Min with questioning eyes, waiting for her explanation.

The same astonishment appeared on her face, and Wu Min repeated: "The instrument shows that the entire mountain peak is constantly emitting penetrating particle beams, the rock structure of the mountain contains radioactive elements, and the metal detector also shows a strong metal reaction. My guess is that the mountain in front of me is probably a metal mountain, at least in addition to the outer layer of rock, there should be a radioactive metal core inside. With such radiation intensity, the volume of the metal core inside is absolutely amazing. ”

If this is the case, the problem is big, the human body is exposed to high-intensity radiation, and with the increase of the dose, some harmful effects will randomly appear, such as inducing leukemia, thyroid cancer, etc., and may also cause symptoms such as genetic mutations in the body's genetic material. Of course, this takes a certain amount of time, and the intensity of radiation described by Wu Min is that it will immediately cause cell damage and death throughout the body, and it will kill people in just a few hours.

The discovery of radiation is undoubtedly a huge barrier that stands in front of the sand-buried ancient city, a barrier that living matter can never pass. The enthusiasm of the people has been discouraged, and the results of many days of hard work have been lost, and the fact that no one can accept is in front of them.

Jiang Erye didn't care much, it seemed that the hardships and difficulties that this trip was about to face were ten percent prepared, he smiled: "Two years ago, we created an artificial metal coating in the European research center, using a precious metal as a coating additive, the most significant effect of the finished product is to absorb harmful substances such as radiation in nature, and even block and absorb nuclear radiation at close range, the cost is very expensive. ”

Anti-radiation coatings! Second Master Jiang's words were like a thunderbolt from the sky, and everyone's extremely disappointed mood turned around, Han Qingxin thought to himself: "You have even researched this kind of thing, there is nothing else that the Jiang family can't do, it is simply above the country, and the scientific research ability of this family coupled with the huge economic strength is simply terrifying." ”

"Economy, scientific research, and militarized equipment construction, you have done so much beyond the scope of the family or an organization, I am curious about what your Jiang family is planning?" Han Qingxin didn't care whether the paint that Jiang Er Ye said really had such a miraculous effect, on the contrary, what they did made him frightened.

"Tell me, what do we want to do? Ha ha. Second Master Jiang burst into a burst of wild laughter and did not answer Han Qingxin's question from the front.

"I know you're from the military, and a small person shouldn't be in charge of too many things. You should be honored to see the ruins of an ancient civilization, so don't think too much about it, right? ”

Night is approaching, the charm of the ancient city attracts tireless explorers, they can't wait for a moment, Jiang Er Ye decided to set off overnight, and ordered everyone to follow the bluestone ancient road all the way, the end of the ancient road is the foot of the mountains.

After walking for about three hours along the bluestone road built in an unknown year, the towering mountain stood in front of them as the last rays of afterglow under the clouds shattered like a little phosphorescence, and the moon and stars were sparsely raised in the sky.

The majestic and steep are not enough to describe this mountain, like a huge shadow lying on the plain in the dark night, everyone is frowning and worried, not to mention the high dose of radiation, but such a slope of the mountain to climb with bare hands is a great test of physical strength and endurance, and they do not have professional climbing equipment, in case of falling down, there is no possibility of survival.

Zhu Beichen stopped and watched, and sneered at Jiang Erye: "Second master, climb half with your bare hands and lose a layer of skin, I am afraid that I will fall into a pulp before I reach the top of the mountain." ”

The mountain and dangerous peaks are climbing, Jiang Erye smiled slightly: "Your IQ is very high, can your EQ be lower?" Haven't you ever wondered why the ancients chose to build a city in such a dangerous place? ”

Whether it is a dynasty or a dynasty, the location of a city is cautious and cautious. The modern urban layout has fully considered the convenience of transportation, and the construction of the transportation line railway is reflected in this, how could the ancients with superb architectural skills not consider the traffic problem, and build a city in a dangerous place surrounded by mountains is undoubtedly self-isolated?

"The location of the city is close to the water source, and the second is to consider the transportation problem, which are the two major considerations for the location of the ancient city. Of course, there is a third point, that is, because of the needs of war city defense, the dangerous terrain is theoretically more conducive to defense. "If I want to take the school into my ancient history and culture, don't I know the influencing factors of site selection?
