Evening.

Xu Ran sat quietly in the artificial intelligence control center in the basement.

There was a large screen in front of him, and some video content was playing on it, and it felt like he was watching a documentary.

This documentary looks a little boring, but Xu Ran is very patient.

Because there are details that are impossible for the parties to discover, it is possible to hide them from these unnoticed perspectives.

……

The vast desert, the ripples of the sand.

For thousands of years, it has been a place of desperation, with no grass growing except for the eternal sand dunes and the misty yellow sand.

It is also impossible for the robot's surveillance records to always capture these scenes that are not helpful.

This was the eighteenth day since Ye Wudao's team entered the desert.

Of course, they couldn't stay in the desert for the past eighteen days, and the problem of supplies alone would have made them fully prepared.

They are exploring treasure hunting, not going to travel and play, and it is even less likely that human life is not taken seriously.

In fact, every seven days of exploration, they would mark up there, and then they would resupply and rest at the supply points that had already been prepared.

Rest for a day or two and get ready before you continue your journey.

The first two times these people circled the desert, but they found nothing, and the search for the remains of the Shigan River did not make any progress.

It is said that the information that Ye Wudao has mastered is relatively comprehensive, and he has also done many certifications with the professors of Chengde for the general location of the Shigan River ruins, and it is still possible to point to an area that can still be done.

However, in the vast desert, there are still no valuable clues to find.

In this situation, the mercenaries who accompanied them were a little unhappy, and they felt that they were running out of patience for the job by going around the desert like this all the time.

And these mercenaries have another intention, that is, they want to add money, the last time they encountered a sandstorm, they lost some of their equipment, and even one person went missing.

The most troublesome thing is that they already know that there are some unknown forces hanging near their team, as if they could attack them at any moment.

This is only a record of a mercenary captain's negotiation with Ye Wudao and the professor before the camp was ready to leave.

Ye Wudao didn't quarrel with the mercenary captain, after he understood the other party's intentions, he happily added money to them, and those mercenaries were motivated.

So, Ye Wudao and the others set off again, this was their third exploration process.

And this time, they no longer didn't use the route of the previous two trips, Ye Wudao decided to go the opposite.

It's not the opposite direction.

Instead, their way of exploration is no longer the carpet-like meticulous exploration of the previous two times, but they reverse the calculated regional coordinates for investigation and exploration.

Xu Ran watched the approximate coordinates calculated by Ye Wudao and the professor using the robot during the monitoring.

When they reversed this coordinate, Xu Ran was surprised to find that they had finally inadvertently made a major clue this time, that is, the reversed coordinate was very close to the one-way coordinate value that Xu Ran had mastered.

Maybe even Ye Wudao and Professor Chen themselves didn't know, they had roughly calculated the coordinates of the Shigan River ruins by mistake.

Although there is a little error, for the entire ruin, if you can find a part, it is considered a success.

It can be seen from the surveillance.

This time, Ye Wudao's luck in their exploration team seemed to be good, and they did not encounter sandstorm weather.

They searched in the opposite direction, and soon found a small oasis hidden deep in the desert.

Although the oasis was only two hundred square meters in size, in the oasis they found a strange plant.

The plant grows under a shady sand vine with only two leaves, and the leaves change color and shape over time.

When Professor Chen saw the plant, he was overjoyed.

He flipped through his research notes and compared them, and decided that the plant should not grow in the small oasis, but should be attached to a kind of human-faced lizard creature that lives near an underground river, because it is a companion plant of a special kind of human-faced lizard creature.

Professor Chen believes that as long as the human-faced lizard can be found, it will not be difficult to find the ruins of the Shiganhe wall.

Because according to many archaeological experts and professors, after research, they agree that Shiganhe is not only an ancient relic of Zhending culture, but also a city, although he does not have a moat, but there is an underground water system as a defense system, and in the vicinity, there are traces of human face lizard life have appeared many times.

However, the experts also concluded a definite clue, that is, the Shigan River was buried under the desert, but it can still flow, the specific law is relatively vague, but there is still a time interval.

This is also the main reason why the remains of Shiganhe have never really found his clues for thousands of years.

The discovery of that small oasis made the exploration team very excited.

They didn't stop there, but after replenishing some water, they set off on their way again.

The rest of the way was desert, and there was nothing particularly noteworthy, and the robot stopped recording and went to sleep.

After skipping here, it was already evening again.

The night view was a little blurry and not as clear as I could have been, it was in a camp in the middle of the desert.

The people in the camp were all outside with fires and eating, and some were resting, and they didn't seem to have anything special.

However, there was no trace of Ye Wudao, Professor Chen, or the Xingjia Exploration Team in the camp.

Xu Ran felt strange, how could the robot record such a boring scene, could it be that he didn't find any clues because of the perspective problem?

So, Xu Ran switched the perspective of monitoring and quickly discovered the problem.

This was recorded by another robot in a different location, near the back row of the tent, where two sneaky figures walked outside for a while, then buried a wine bottle on top of a sand dune, and then quietly returned to the camp.

Seeing this scene, Xu Ran frowned, he had the impression that these two members of the expedition team were two of them sent out by the Xing family, what did they want to do here?

The two went out for a short time and were not discovered, but they didn't know that the robot had recorded them, and now they were seen by Xu Ran again.

Then, after a flash of the screen, it seemed that the time had entered the camp around one o'clock in the morning.

I saw that Ye Wudao, Professor Chen, and the expedition members of the Xing family had just returned, and after they handed over to the people on duty in the camp, they began to rest.

But Xu Ran found from the monitoring that there was a very bulging place in Professor Chen's backpack, bulging like a head, but he didn't know what it was.

It was clear that the thing was holding up his backpack, and it was even a little too much to fit, and Professor Chen had forcibly stuffed it into his bag, and they should have brought it back when they went out at night.

This time, Professor Chen and the others went out, and they did not follow with the robot, and they didn't know where they had explored, and they would come back with something, they should have found something, but these were not photographed by the robot.

Xu Ran couldn't help but wonder if someone had discovered that the robot was secretly monitoring their whereabouts and records, so that they could take precautions?

But it doesn't matter.

For Xu Ran, what he cares about is not whether they suspect robot monitoring, but as long as they still take the robot to explore, then Xu Ran will definitely get new clues, they don't know that there is a satellite in the earth's space facing their direction and locking the robots with terminals in real time, there is no signal connection between the robot and the satellite will be completely interrupted, unless they go to some places where the magnetic field is extremely strong and can isolate any signal.

However, since it has reached that point, it means that the ruins of Shiganhe may have been found.

The rest of the time was basically garbage time, Professor Chen entered his tent and never came out, and the others began to rest, and then there was no further record.

The time on the monitor flashed again, and the picture shook slightly, and it was already morning, and the team set off again.

This is a fast-forward monitoring record of the robot, and the speed of the screen is very fast, but the coordinates of the team's exploration are always clearly recorded.

This time the team advanced at a distance of seven kilometers.

When the fast-forward surveillance footage returned to normal when it reached the seven-kilometer position, the team was lucky enough to find a small oasis.

In fact, it was the eye of the desert, and to put it bluntly, the groundwater seeped out, causing some green vegetation to grow in that place, forming a small pool of water.

The discovery of another small oasis has brought the vitality of the team to a new level.

However, during the surveillance, it could be seen that Professor Chen and Ye Wudao's faces flashed with joy in an instant, even if they were very careful not to be discovered, but the robot recorded these very faithfully.

This also shows that they are one step closer to the target clue.

That's all for this record, followed by a hurry, a very boring part until the evening.

However, the team's good fortune ran out in the evening.

When they were about to find a place with sand dunes to block the wind and sand to camp and rest, a group of people unexpectedly encountered desert black scorpions, which were very numerous.

The black scorpion was still a mercenary, and he accidentally stepped on something and got out of the sand.

When the scorpion was about to attack, the mercenary took out his dagger and killed the scorpion.

It doesn't matter if this killing, it's like stabbing a hornet's nest, but after scorpions come out from under the sand one after another and scatter around, it's like a black curtain slowly opening, and the scene is still quite infiltrating.

When the people in the team saw this, it was obvious that this place was no longer suitable for camping.

The group immediately evacuated, and even when they left, a soldier was drilled into the body by a black scorpion, and then bitten, but in less than a few minutes, the mercenary died of poison, indicating that the scorpion was very poisonous.

As the mercenaries retreated, they would shoot the black scorpions that were chasing them.

However, the appearance of highly poisonous black scorpions indicates that there must be relics left by the ancient kingdom of the Western Regions in ancient times.

Sure enough, after walking about three kilometers, they came across a ruined wall, apparently the ruins of a remote town in the middle of the desert.

The team stopped to explore the ruins of the town, and through some fragments, Professor Chen concluded that the ruins were a remote town in the ancient Western Regions and the end of the country, which was abandoned and buried in the desert, but also knew how long it took for the sandstorm and the movement of the sand sea to be reappeared.

After arriving here, Professor Chen asked to camp outside the ruins of the ancient town to rest, but Ye Wudao felt that he could go inside and camp in the middle of the ruins of the ancient town.

In the end, Ye Wudao succumbed to Professor Chen's suggestion and camped on the periphery to rest.

It wasn't until around four o'clock in the morning that the robot once again photographed Professor Chen, Ye Wudao and others quietly leaving the camp without taking the robot with them, and went to explore alone.

This time it wasn't long, and it only took them an hour and a half to get back.

However, when I came back this time, there was obviously one less person in the team, and two people were injured in the legs and were carried back, so the situation was obviously wrong.

The people in the camp asked them about the situation, and they only said that when they were exploring the ruins, they accidentally ran into those decaying buildings and fell after stepping on the air, and one of the team members fell and was buried in quicksand, and they could not rescue them.

Time passed quickly again until the sun had just come out, and the team had finished their camp and set off again, this time in a northeasterly direction.

Walking in the northeast direction, they passed through the general area of the Ancient Western Regions Essence Kingdom and paused for half an hour to rest, and then they had no intention of exploring the Ancient Essence Kingdom, and walked in the northeast direction again, looking as if they were going to the northwest direction of the Ancient Late Regions and the Kingdom, which was the desert death area.

This time, there were no more anomalies in the team, it was still a boring desert journey, and the day passed like this, and the robot did not have much valuable monitoring records to send.

However, after the third day, when the robot was turned on again, it encountered signal interference.

Not only the robots were disturbed, but even some electronic instruments and tools such as compasses used in the team were also affected, which was obviously not normal.

The intermittent footage sent back by the robot was completely cut off until they reached the vicinity of a mountain that was not very high.

And after Xu Ran watched and monitored this position, it was completely interrupted.

Judging from the time when the robot sent back the last monitoring content, it was 10:57 a.m. yesterday, and a day and a half have passed now, but the satellite has never been able to search for the robot's terminal tracker signal, which means that the magnetic field in that place is very strong and is completely isolated from the outside world.

I don't know if this situation is good or bad.

But Xu Ran guessed that the expedition cluster might have already made some discoveries.
