Chapter 157: Prehistoric civilization?

Lin Wei, Zhao Guo, Wu Qi and three people surrounded the A7 area with hundreds of people. Some unidentified construction workers thought that something terrible had happened. For a while, both sides were ready. .
Soon, Wang Fugui drove Ye Fan and Ye Qingcheng to here with a big G.
Ye Fanla opened the door and stepped out of the car. The heavy person surrounded by the crowd saw Ye Fan at a glance, and shouted, "Mr. Ye! I am here!"
At this time, all the security guards saw Ye Fan and Ye Qingcheng arrived, and they also automatically stepped aside, letting them walk in.
"Digged something? Take me over and see." Ye Fan was also frowning at this time.
"One hour ago, based on the rapid extraction of samples by geologists, a small piece of material was determined according to the method of determining the relationship between mother and child of radioactive decay.
They sent the measurement report 20 minutes ago, Mr. Ye, do you know how old it was? "He said with a solemn expression.
"How many years ago? A hundred years? Thousand years?" Ye Fan estimated conservatively. If it were old-fashioned controlled items, they had been around since the Tang Dynasty.
The distance is more than a thousand years now, if this is the case, it is not surprising.
Contact the relevant department to submit it and report the situation truthfully. It is no problem to start work normally.
"Ten thousand years before history." He lowered his voice heavily and spoke to Ye Fan.
"Ten thousand years?! This is impossible. At that time, human beings were still in primitive society. No, at that time, even the three emperors and five emperors in myths and legends were never born.
How could there be controlled items? This is impossible. "Ye Fan's heart sank suddenly, and he directly denied the heavy words.
At the same time, he also realized that the matter was important. Except for Shen Zhong, Ye Qingcheng, Wang Fugui and others, other construction workers, as well as security guards, all retreated 300 meters to stand by.
Generally speaking, the error rate time of the method of determining the relationship between mother and child of radioactive decay can be basically reduced within a hundred years.
Because according to the law of decay, it can be concluded that the number of radioactive atoms in the daughter body is so as long as the ratio of the number of mother and child atoms is measured, the age of the corresponding item can be obtained.
If it is not used to determine the age of the object, but to test the age of the rock, then the age error rate is even smaller, and can basically be reduced to less than 50 years.
Because the lifespan of uranium-238 (T=4.5×10^9 years) and uranium-235 (T=7×10^8 years) is long enough, if it is used as a clock, a comparison table is broken down, the age of the rock It was exposed in an instant.
Therefore, instead of doubting the age error, it is better to doubt whether the geologists' determination has made an operating procedure error.
"At the beginning, I thought there was a problem with their measurement report. Now they have started the second round of measurement. They are all veteran geologists and have a long-term cooperation with our construction company.
It also has a good reputation in the industry. If there are errors in the first round of testing, it is understandable. If there are errors in the next five rounds of testing, then there is only one explanation. "He frowned and said.
"Prehistoric civilization?" Ye Fan thought of such a possibility.
"Well, there is only this kind of explanation." Shen nodded in focus.
"How likely is it that they will have a measurement error?" Ye Fan at this time was also a little unsure.
"Theoretically, the probability of error will not exceed 1%, because they use the method of determining the relationship between the mother and daughter of radioactive decay, two of which are measurement branches.
1. Potassium-argon method to determine the age of objects, 2. Uranium method to determine the age of surrounding rocks, each of the two measurement methods is divided into three groups, a total of six measurements,
Twenty minutes ago, the age of the corresponding object had already pointed to 10,000 years ago. Next, we will wait for the measurement report of the age of the rocks around the object. If the surrounding rocks,
It was also 10,000 years ago and was buried next to those controlled items, so I don’t need to say more about the result. "Shen Zhong still believed the expert's words very much, and then spoke to Ye Fan.
"Those controlled items are in the pit in front. Mr. Ye, since the excavator master dug out, we have not moved the site again, except for digging the pit deep.
Apart from digging a bit bigger, no changes were made to the surroundings. "He pointed to a large hole in front of him, and said.
"The pit you dug is really big enough." Ye Fan said as he looked at the big pit with a radius of almost fifty meters.
"No way, this is professional ethics, you still have to fill it in at that time." He shrugged and followed Ye Fan.
At this time, Wang Fugui, Zhao Guo, Lin Wei, and Ye Qingcheng also jumped out of the one-meter deep pit. From the conversation between Ye Fan and Shen, they already knew the seriousness of this matter.
You must know that it is a prehistoric civilization, a civilization that has been searched for by historians of the past, but can't ask for it!
If this matter is exposed today, maybe the eyes of the whole world will be focused on this place, maybe the reconstruction of Datang Technology will have to be put on hold.
Even in order to excavate the surrounding prehistoric civilization relics on a large scale, a red-head file was issued, and the entire Datang Technology had to move out of this place from then on.
The loss is not insignificant.
When Ye Fan approached the place in the center of Dakeng, his mind suddenly buzzed.
"Isn't this?...Is it impossible? Absolutely impossible?" Ye Fan suddenly took a breath when looking at the controlled items in the center of Dakeng.
No wonder Shen Zhong said that this thing is definitely not a general controlled item.
The appearance of the ordinary rifle and the white painting, although the white painting has begun to turn yellow after thousands of years, and even some parts have begun to corrode, Ye Fan can recognize what this thing is at a glance.
"Energy particle beam ray gun? Why does it appear here? No, this is not my design. This design is much behind my design." Ye Fan couldn't hide the shock in his heart, and murmured.
Because there is no consciousness transmitter, Ye Fan relied on his hand to set and draw drawings to introduce the energy particle beam ray gun into Origin, and let the artificial intelligence arrange production.
If you count it by time, he has just built the first energy particle beam ray gun, and it is absolutely impossible to appear in such a place.
And there are 18 so many in the range of 10 meters ~EbookFREE.me~.
Ye Fan looked at the energy particle beam ray gun in the big pit, and a familiar feeling emerged spontaneously.
"Why... I feel so familiar." Ye Fan gently stroked, the white paint that had been almost oxidized, frowning.
"No, this familiar feeling doesn't seem to come from the kind of familiarity from the body, but more like... from the mind?"
"How does it feel? Familiar?"
"No, it's the loneliness facing the vast sky, the vast earth, and a drop in the ocean."
"No, it's more like...resonance!"
Ye Fan's thoughts were very confused at this time, all kinds of messy information rushed into his mind, and his head was faint and up, as if he was thrown into the washing machine and stirred wildly.
A huge sleepiness hit, Ye Fan's eyes went black and he fell directly into the pit.
