At this time, it was about two o'clock in the afternoon, the sky was clear, although it was very hot, but the desert was lonely, and the beautiful scenery of the nine days of solitary sun was still beautiful.

No one noticed that after the caravan left, a sand pattern suddenly appeared on the sand behind them, writhing to reveal a pair of horns, and the cold triangular eyes stared ahead for a few seconds, and then sank into the sea of sand.

"It's rare to have a local basin in the desert."

Under the leadership of Han Dong and Zhao Aiguo, everyone successfully reached the land of grimaces. Professor Wang first rode a camel around the periphery of the place, nodding his head in amazement.

"Professor, the skull I cut off is over there." Han Dong seemed to be meritorious, and took the lead of his boss and walked to the shadow before, completely forgetting who found the skull first.

As Professor Wang walked, he observed that the temperature here seemed to be two worlds compared to the outside. Even if the sand dunes block some of the sun's rays, it shouldn't have such a refrigerator effect, right?

The point is that this shade makes Professor Wang, who has a lot of experience, feel a little cold to his bones. What the hell is going on?

"No, that's it."

Han Dong pointed to the skull embedded in the hill and looked at Professor Wang. In fact, this was purely superfluous, and the professor had already crouched down to observe.

I don't know how many years have passed, but this skull has become a fossilized skull. It should have been a person with a national character face before it was born, with empty eyes filled with yellow sand grains, as if it was a pair of yellow eyes, staring indifferently at strangers who had come across thousands of years.

Professor Wang used a small sapper shovel to gently dig sand around the skull, and he ordered the students to come around, but they were not allowed to do it. This time, Professor Wang decided to clean up the precious skull fossil himself.

Perhaps, like the skull of the Peking Man Cave Man, it has become an archaeological discovery that shocked the whole country.

Pang Weimin and Zhao Aiguo observed from all around. This hilly land is so weird, especially the one that Zhao Aiguo said about the black shadow's "Go!" The word made him very interested.

First of all, Pang Weimin deduced that there was really someone here, and since it was a person, he would definitely have an exit to escape from this place after being discovered by Han Dong and Zhao Aiguo.

Pang Weimin repeatedly confirmed with Zhao Aiguo several times, and the latter did hear the word "go" clearly, and it was definitely not a rumor or echo, which he was very sure of.

Based on the trust they have been with for more than ten years, Pang Weimin and they began to look for these clues, but after carefully searching twice, they still did not find the slightest clue.

Secondly, if it is not a human, then it may be a sound made by some kind of desert creature at what time period, very similar to the human pronunciation of the word, but no trace of animal infestation was found no matter how you searched for it.

Is it really a ghost scream? If so, why does it just say "go"? Instead of what is commonly referred to as "go die", "look for death"?

Pang Weimin didn't understand, so he took out the yin and yang fish pendant to see. He flipped through it and found no record of the ghost's scream. This yin and yang fish pendant records a place, compared with this place, but it does not fit.

"Professor, why doesn't this skull have a skeleton on the lower half of its body?" After Professor Wang took out the entire skull, Xiao Li wondered.

"Maybe the wind blew it away, or maybe it was drifting away with the sand dunes somewhere else." Professor Wang carefully put away the fossilized skull.

"Professor, I don't think this skull fossil looks like an ancient Loulan person, but it looks a little like our Central Plains people." At this time, a student spoke again, and his words surprised Pang Weimin, who came over. How could the people of the distant Central Plains die here alone?

"You see that, too? That's right, judging by the appearance and characteristics, this skull is very similar to our Han people, not the Guloulan people of the ethnic minority. So, there must be some story hidden in this skull. Professor Wang said with a smile.

"Could this be the legacy of the merchants or border people who traded between the Han and the Guloulan people at that time?" Xiao Li asked.

"It's very likely, but the question is, how did he die? Why are there no other bones around? ”

Professor Wang's words made everyone fall into deep thought, and for a while the whole venue was quiet, and even the sound of the wind could not be heard. Zhao Aiguo's heart was furious, and the feeling of chilling down his spine came out again.

"Alright, don't be stunned, let's try to dig and see if there are any other discoveries. This basin is about the size of ten football fields, and we should not bloom all over the place, so I suggest starting to dig in the sand near this skull. ”

Professor Wang cleared his throat and began the arrangement, and his students immediately took out the sapper shovel from the package. Everyone gathered the packages and supplies into one corner, and Han Dong was in charge of taking care of them. Xu Shan followed Professor Wang's side as always, never leaving an inch.

Bahar, on the other hand, was responsible for preparing the torches after dark after the camels had been placed. Excavating the sand is not a one-and-a-half thing, it is estimated that it will not be until night.

Pang Weimin and Zhao Aiguo also participated in the excavation, this place is strange, if you just stand and don't work, the feeling that makes people's spines hairy is too bad. It will be more comfortable to work and sweat a little.

The sandy basin has been transformed into an excavation site, clanging. Professor Wang was old, and accompanied by Xu Shan, he went around to check the excavations.

"Everyone, pay attention, don't go near these dune walls when digging, if we dig down the dune walls, we will be buried alive, or we will become skull fossils found by future generations." Professor Wang was half joking, half reminding.

The sand dunes are originally mobile, but they have not moved for countless years, perhaps because they have been tamped by the materials added by the Guloulan people, and these dune walls can stand for thousands of years without falling, which can be called a desert miracle. Therefore, they naturally avoided digging the roots of the wall.

Night soon fell, and Bahar and Han Dong lit eight large torches and inserted them in eight directions, illuminating the entire excavation site. The flames of orange torches danced, driving away the desert chill at night.

Places with fire are always warmer, and in this desert basin it is a little cooler during the day, and it is even more shady at this time, and it is a completely different world from the hot desert outside.

Farther out, some sand lines gradually appear on the sand. One, two, more, the direction of the flow of the sand is impressively the glittering sand basin.
