At this time, the hand shovel that Dongfang Chen said in his mouth was referring to an intelligent aid he had selected from the assistance he had received from Proxis. After the upgrade of Akama, it was born into a powerful intelligent assistant specially designed to detect scientific expeditions, code: UA02.

Dongfang Chen thought that this name was troublesome to shout, so he gave it a pleasant name: hand shovel.

Hearing the master's question, Dongfang Chen's black robe swayed, and a black metal ball the size of a ping-pong ball flew out of the cuff, and an intelligent voice came out: "Master, the probe is reasonably distributed, and the downward probe progress is normal, and it is about an average speed of 0.7 meters per minute." ”

Dongfang Chen didn't say anything more after listening, and waited patiently for the results.

Ten minutes later, the hand shovel suddenly issued an alarm, and a fast and urgent voice came out: "Report to the owner, there are two groups of probes at 147 degrees southwest to detect geological stratification at the same time, the depth of stratification is 8.3 meters, and the analysis data is being uploaded......

A set of probes at 231 degrees are in contact with artificial materials, the contact point is 10.7 meters deep, and the analysis data is being uploaded......

Four groups of probes at 13 degrees are in contact with the artificially modified granite level at the same time, with a depth of 14.5 meters, which is preliminarily speculated to be the top or bottom layer of a large stone building, and the analysis data is being uploaded......"

In this way, as the alarm sound became more and more frequent, Dongfang Chen commissioned the RC engineering research and development department to manufacture and process 1,000 multi-functional miniature detection robots codenamed "probes" according to the design drawings and assembly instructions provided by Akama, and discovered one after another.

With the integration of all the uploaded data, a large remnant of an ancient urban community was outlined. It is also known that the average depth of the remains ranges from 8.5 to 23.2 meters.

Dongfang Chen didn't have time to wait for the excavation of thousands of square meters of underground ruins, even with the current technical means, to completely excavate and clean up such a large area of ancient city ruins, it would take at least ten years to start.

That kind of rough work is not something that needs to be considered now, now he just needs to accurately probe to see if he can find important cultural relics such as the gold plate of the ancient city of Biro, in order to directly determine the true information of the ruins here.

If what is found can directly prove that the ruins are the ruins of the ancient Babylonian kingdom, then Dongfang Chen will go all out to find all the cultural relics with words, graphics, and sculptures. From the graphic records, see if the legendary Tower of Babel of Babylon is true.

This is Dongfang Chen's entire plan. Since there are surviving ancient documents that prove that the kingdom of Babylon once mentioned the word "lighthouse," I will dig this kingdom out of the earth and bring the name of Babylon back to life!

In fact, he was not interested in what the so-called probe robot had detected, mainly because he wanted to get the average depth of the remains underground: 8.5 to 23.2 meters.

With this data, Dongfang Chen can appear in person.

He first used the communicator to order Hamed: "Your work is over, all board, retreat to a safe distance."

Then wait for me to tell you to do the next step. ”

After the sound of the four transport planes disappeared into the night, Dongfang Chen spoke again: "Hand shovel, let your little brother recover all the drilling status, close the shell, and turn on the amplitude reflection mode." ”

The surface of the metal ball lit up with a few green light streaks, flashed a few times, and had already given orders to a thousand probes.

Dongfang Chen lifted off the black robe on his body, revealing his combat uniform, and then clicked on his wrist a few times, dozens of thin blue lights shot out from the left chest and abdomen of the combat uniform, which swept across in the blink of an eye. Then, next to his left shoulder, a complex blue pattern nearly a meter square appeared, constantly changing, beyond visual comprehension, supergeometric objects that were constantly superimposed and rotated infinitely, as if interpreting the endless mysteries of time and space.

As for the storage system attached to the high-level combat suit: the super-space-time grid, Dongfang Chen was already surprised, and opened the boxy "blue door" without a sound, and took out a black rectangular thing nearly three meters long, which looked like a coffin.

This thing is the battle of the Mariana Trench more than ten years ago, which slaughtered hundreds of thousands of innocent human beings and completely wiped out an integrated aircraft carrier battle group of the US Navy.

Earlier, through the information provided by Elusphinser, it was learned that there were two executioners, one had been self-destructed in the Battle of the Mariana Trench, and the other was in the hands of Amani.

At the beginning, the God Butcher fought with the Broken Squad in the nameless mountains and forests of Eastern Europe, and finally Amani surrendered, not only handed over all the treasures, but also handed over all the technology and equipment, including the only single tactical weapon executioner on the earth.

According to Dongfang Chen's original idea, he planned to package this thing and some other alien technology weapons to the United States, so that they would pay the price that they would not be able to turn over for a long time.

But Prosius immediately made Dongfang Chen change his mind with a few words: "Stinky boy, executioner, and some other weapons and equipment, at present, they can't reflect their value on the earth at all, can't we use them to go to the universe galaxy in the future?"

Why should an enemy who can be killed with one shot do it?

Besides, even if you are worried about the source of this batch of arms, you dare not use them yourself, and you will not sell them on the black market? Do you think that the God Butcher Group is very rich now? Although the net worth of assets is quite solid, but just like the situation I was in the beginning, the things at hand are either contraband or black goods that cannot be seen, do you dare to take them out?

Although you have abundant materials, if you go to a place where the universe can trade, there is zero cash deposit. Wake up, Captain!"

So, Dongfang Chen dispelled that ridiculous idea, and sorted a large number of weapons and equipment that had been collected from the guards over the years and carefully preserved them.

Who is the leader of the God Slaughter Regiment? He is a great god who doesn't even need spiritual weapons, let alone technological weapons, and he doesn't even look at them directly. But he he's heeded Akama's advice, and there's one thing that can help him a lot in this kind of extremely difficult operation that requires him to run around the globe and quickly probe and collect information hidden deep underground or in the waters, and that's the executioner!

Although this thing is a terrifying mass killing weapon, it integrates many high-tech technologies of the Empire. If it is science and technology, it will have universality, and the military can often be used for civilian use. The executioner's other methods are not mentioned, but its map attack mode: ultra-high frequency repeated multi-source pulse cannon can solve Dongfang Chen's most difficult problem at present.

Although it is known as the map attack mode, despite its complex operation and bluffing formation, the most basic core principle could not be simpler: energy pulses.

When the Warden Shokmang used the executioner, the memory energy had been depleted, so he hastily used up the remaining energy and then self-destructed because he did not have the nine types of energy crystals necessary for the executioner. It's the same with Amani, without energy crystals, no matter how awesome the weapon is, it has to be turned into scrap metal.

But Dongfang Chen has it, so the executioner uses it as much as he wants. As for why the executioner's other functions can't help Dongfang Chen, the map attack mode can, because the power of the energy pulse, pulse frequency, and pulse type in this mode can be adjusted freely.

By adjusting the power of the ultra-high frequency repetitive multi-source pulse cannon with an appropriate amount of adjustment, reducing the pulse frequency, and selecting a soft long-wave pulse, this killer will immediately undergo earth-shaking changes and become a super detection device.

But there is a problem here: how much is the right amount of power to adjust? What is the value of the pulse frequency? How long is the wavelength of the pulse needed to choose a long-wave pulse? These all need accurate values. Otherwise, if the parameter is too small, the desired effect will not be achieved, and the parameter input will be too large, then it will not be detection but destruction.

Because of this, Dongfang Chen, inspired by Akama's education, selected and transformed an intelligent UA02 for professional archaeological exploration, and did not hesitate to spend a lot of money to build a complete set of execution system for UA02: probes.

Only by allowing UA02 to accurately locate the target, analyze the distribution of geological water quality composition in the target area, and most importantly, it is necessary to detect the depth value of the target area. Because these are all related to how much "force" the executioner needs to use in order to achieve the optimal effect of not only meeting the detection requirements, but also not destroying the target.

At the same time, thousands of probes distributed at specific locations in the target area are closed to amplitude reflection mode before the executioner initiates the detection. Under the interference of thousands of amplitude reflection sources, the energy pulse waves emitted by the executioner will be scattered and overlapped continuously, almost filling the target area space infinitely, and the clearer the detection results will be, and it is not an exaggeration to say that the slightest detail is present, just like shooting with a camera panorama.

After explaining all this working principle to Dongfang Chen, Akama once said something like this: Commander, your hand shovel and the executioner work together tacitly, not to mention the depth of hundreds of meters in the groundwater, even if they are allowed to probe the center of the mantle, it is only a matter of time.

In the future, when you come to the universe, as long as you want to know about the secret realm of ruins and the history of civilization, our method is also universal.

This is the holographic archaeology that is currently more popular in the universe, it's very powerful!
