The bad emperor of Tang Dynasty

As soon as I saw Guo Nuan, I felt his murderous aura. As soon as I smoked, these sand monks dived into the sand to escape, as if they had practiced the earth escape technique. After the lizard dived into the sand, it was like swimming in water. Quick and agile.

However, Guo Nuan, who is good at observation, learned a little trick to prevent cold and cool down from the lizards. These lizards always like to drill into the sand when they have nothing to do. Guo Nuan was curious and tried to dig a sandpit. He asked Doma to bury his whole body Not to mention that this method is really effective, Guo Nuan felt the coolness of the sandy soil at the foot of the shady dunes, so Guo Nuan and Doma dug two sand pits, buried themselves and poked out their two heads, It was very hot at noon during the day, but Guo Nuan and Doma, who buried their husbands and wives graves in the shade of the sand dunes, were very comfortable.

Of course, besides the fact that the sand can insulate Guo Nuan and Doma from heat during the day, they also bury themselves in the sand at night, which undoubtedly covered themselves with a thick insulating quilt, but the sand on their chests was slightly out of the way. They were a little sulky, and compared to the severe cold of several degrees below zero, sulking didn't matter at all.

"Pfft," Guo Nuan shamelessly smashed a basketball-sized prickly prickly pear at a sand duck in the bushes, only to see the "hammer ball" that passed through the center of the prickly pear with a cloth strip hit the prickly prickly pear. A poor sand duck, covered with fairy thorns all over, ended the duck's life very sadly.

"Oh, it's great," Doma said after being with Guo Nuan for more than a month, under the influence of Guo Nuan, an unscrupulous guy, she has become a lot more active now, cheering from time to time like a child, at this moment Guo Nuan hit the prey with a hammer and made her very excited. She didn't expect that the prickly pear could be used in such a way.

"Quack, brother's latest invention, the invincible fairy hammer ball," Guo Nuan picked up the dying sand duck that had been acupunctured all over and plucked its feathers on the spot, and soon the bare duck was put on the wooden frame of the campfire. Hastily smeared salt on the skin of the roasted duck.

The salt was collected on the shore of the Gobi Salt Lake before entering the desert. There is a lot of evaporated and dried salt. At least in the environment where sweat evaporates a lot in the desert. necessary electrolyte components.

Stopping and stopping along the way, relying on their rich knowledge of wild survival, Guo Nuan and Doma finally survived the hottest and most desolate desert area.

Relying on the navigation of the stars at night and the geographical position indicated by the wind direction of the sand dunes, Guo Nuan and Doma finished climbing the sand dunes and mountains on No. 11 days after entering the desert.

Standing on a sand dune more than 100 meters away, looking around, the front is a semi-desert area, and some places still contain slightly organic soil.

Pieces of dead trees in the Populus euphratica forest, the dry and huge stumps stand intertwined like living fossils for thousands of years without falling down, and the crooked branches support each other, one plant next to the other.

On the farther side, Guo Nuan and Doma saw a surprisingly small stream, but seeing that the water stream shines brightly under the sun, it is estimated that the water flow is not very large. Of course, even if it is a trickle, as long as there is With running water, Guo Nuan and Doma don't have to worry about the safety of their lives, they can live with water.

There are fluttering reeds, and a few red willows are scattered during the period.

"Look, there seems to be a house over there," Doma excitedly pointed to the hidden land behind a row of reeds.

"Quack, it really is," Guo Nuan smacked his mouth, and he also found a wall on a low hill over there, but it was lonely and dilapidated.

"But it looks desolate, is there anyone living there?" Doma asked doubtfully.

"Let's see first," Guo Nuan took Doma's hand and ran down the sand dune, and the two ran towards the stream over there excitedly.

"This..." After a while, Guo Nuan and Doma arrived in the ruins of a desolate and dilapidated city. He and Toma looked at each other. Undoubtedly, there is still no popularity here, and they have not had much contact with human society for more than a month. Guo Nuan and Doma now find that Kong is extremely happy, pouring a pot of cold water on their hearts.

The beacon towers and watchtowers of the Qin and Han Dynasties, these rammed earth buildings can still be distinguished under the erosion of the years. This is a city with a radius of several miles. Guo Nuan guessed that this is an ancient military stronghold, standing on the mound On the road, he counted, there are no less than 200 houses in this square.

The site where the city can be built in the depths of the desert, the ruins in front of it seem to be a very prosperous commercial transfer station at that time.

On the west side of the city, Guo Nuan and Doma found a few pieces of broken porcelain in a soil room with collapsed walls, and the rest were broken bricks and decayed iron metal.

Guo Nuan pulled out a collapsed earth wall, revealing a few pieces of shells inside the wall. He was also surprised to find that there were fossils of prehistoric marine molluscs among the rammed earth stones.

"Well, why are there shells in this wall? Isn't this area a desert?" Doma was very surprised. She thought it was incredible. In the mountains of the plateau in Tubo, her subjects once picked up shells on the high mountains and donated them to others. She, let alone the plateau with a slightly better climate, now has shells that should appear in the ocean, but now there are shells in the desert, which makes her puzzled.

Doma expressed her feelings. Along the way, Guo Nuan told her a lot of inscrutable knowledge of geography and astronomy. Now she subconsciously raised this question. Maybe Guo Nuan, who knows everything, can explain it. So Doma think.

"A long, long time ago, that was the barbaric era of the world, an era so ancient that even we humans did not appear. The plateau where you live was once an ocean like the desert here, so there are traces of shells."

Guo Nuan laughed and said, for this open-minded and studious Doma primary school student, he patiently explained and answered the modern knowledge he knew along the way.

"But here is a hundred and eight thousand miles away from the sea. Could it be that the desert where we were standing was submerged by the sea at that time?" Doma tilted her head in amazement.

"Oh, maybe at that time the whole world was almost full of water, so it would be easy to explain, but why there were shells on the high snow-capped mountains? Could it be that the ocean at that time submerged the towering holy mountains?" Duo Ma immediately had a question.

"Well, this scientific knowledge related to the movement of the earth's crust may not be explained for a while," Guo Nuan sweated on her forehead, saying why Dorma, a hundred thousand people, always likes to break the casserole and ask the bottom line, and she is extremely clever and meticulous. She is very capable, and sometimes Guo Nuan's vague scientific explanations will be found loopholes by her, and a series of in-depth questions often cause him to be unable to justify himself.

Who said that Guo Nuan was a liberal arts student in his previous life. He generally knew some natural science knowledge, but if it involves the explanation of profound scientific principles, then there is nothing wrong with him.
