After the passenger ship left the port, Lu Tianyu quietly jumped off the passenger ship and returned to the seaside, found a seaside cliff and cut the wall until the evening, and then put on the flying wing and flew to the east.

This time, Lu Tianyu's target is the Sahara Desert, and the earthlings only know that this is a place of death, but hundreds of millions of years ago, it was a lush and vast forest like the Amazon, but with the change of the earth's climate and the transformation of the sun and the moon, the sea has become a mulberry field, the forest has degraded into a desert, and the cities established by the Martian civilization on the earth have been buried in the years by thick sand.

According to the information stored in the auxiliary brain, the gene therapy warehouse he is looking for is under this desert, but hundreds of millions of years have passed, and no one dares to guarantee whether he can find a gene therapy warehouse that can still be used here, unless the gene therapy warehouse is stored in a certain space, as long as the space energy is not lost, it will not be damaged even if it is stored for a long time.

The time flow rate in the storage space is almost zero, and even the most perishable food is not damaged if it is present in it, which is the other biggest use of the storage space in addition to being easy to carry.

The Sahara Desert was formed about two to three million years ago, covering an area of more than 9 million square kilometers, almost the same as the land area of China, and is the second largest desert after Antarctica.

Although Lu Tianyu has the detailed information of the city of ruins in his hand, the area of the ruins is too large, if it is still intact, this buried city should have nearly one million square kilometers, and the main city will not be less than 200,000 square kilometers, what kind of concept is this, think about the largest city in the federation now, it only covers an area of twenty or thirty thousand square kilometers, and if you want to find an instrument only the size of a bathtub from this city, it should be almost the same as finding a needle in the sea.

Area is not the main problem, such a relic is lying quietly underground, will the federal government not know?

The answer is obviously impossible!

But fortunately, this city of relics is too large and is located about a thousand meters underground in the Sahara Desert, and it is undoubtedly a fool's dream to fully develop it with the current technology of the earth.

Lu Tianyu had just gone deep into the Sahara Desert and found a military base, who would build a military base in a desert where birds don't, ordinary people may still think that it was out of secrecy, but he knew that this military base was built on top of an exit from the City of Ruins, which was very obvious.

Of course, Lu Tianyu would not break in, this would attract the attention of the army, and he had the detailed information of the Ruins City in his hands, so he didn't need to clash with the army at all.

Soon Lu Tianyu found an entrance that had not yet been discovered by humans, saying that it was an entrance, but it was actually the underground facilities of the Ruins City, the ground buildings of the Ruins City were buried by the yellow sand, and he had no ability to carry hundreds of millions of yellow sand, so he could only enter the Ruins City through underground facilities.

As the underground facilities advanced in the direction of the main city, about an hour later, Lu Tianyu approached the main city area.

Soon Lu Tianyu discovered a not-so-good phenomenon, the underground facilities here obviously have traces left by human beings, power lines and signal lines lead to the deeper part of the main city, and human lighting equipment is still hanging on the walls.

The only good news is that the underground facilities of the Ruins City are just as huge, and the scope of human exploration is limited to a very small area.

"I wonder if the humans are now controlling the main city of the Ruins City?"

Lu Tianyu's worries are not superfluous, no matter how much use value is still left in the city of relics, as far as the current technology of human beings is concerned, it is still possible to control some important buildings in the main city.

As Lu Tianyu went deeper, the traces of humans in the underground facilities became more and more obvious, and he even found a human laboratory inside a buried building, where there were hundreds of researchers in white coats, who were nervously busy.

Lu Tianyu observed outside the human underground laboratory for a while, and even quietly sneaked into the warehouse where the instruments were stacked, and found that there were not many creations left over from the Martian civilization inside, and most of them were very mutilated, and they had no value in Lu Tianyu's eyes.

The potentially valuable relic creation has been shipped out, Lu Tianyu thought so, and quickly denied this unrealistic idea.

This city of ruins has been abandoned for hundreds of millions of years, it has been attacked by alien creatures at the beginning, and it has experienced countless wind and rain erosion, even if this city is the creation of a fourth-level civilization, after hundreds of millions of years, there are really not many things that can be preserved.

When Lu Tianyu entered the City of Ruins, he found that those Martian creations that looked as good as new, when they were in their hands, were like a piece of rotten tofu that turned into sand between his fingers.

The only good thing is that after the city of relics was buried by the wind and sand, it was isolated from the erosion of wind and rain, and the dry climate in the desert slowed down the rate of weathering, and the city of relics seemed to be well preserved, at least on the surface.

"The target should be to the north and west!"

Lu Tianyu compared the drawings of the Ruins City with the global geographic information, and found that with the changes in the earth's crust, some directions have also changed, but he has taken some detours.

Passing through a long pipe, he lifted the cover plate on the top of his head, and the cover plate weighing more than 100 catties "clicked" and broke into two sections, and a burst of dust rose, choking Lu Tianyu had to hold up a shield to block it.

This should be a medical center in the city of relics, and the auxiliary brain does not know where the gene therapy warehouse will be placed, and the energy inside the city of relics has long been cut off, and the central brain of the city cannot be contacted for the time being, so it can only be found by medical institutions one by one.

Although the medical center is buried under the sand, the interior is quite well preserved, and the good in this case refers to the architectural structure, not the equipment inside the medical center.

This medical center has obviously not been visited by humans, and the furnishings inside are still in their original state, but because of irresistible forces, many of the equipment is in a semi-weathered state, and if you don't touch it, you can still see the original appearance, once you want to do hands-on research, you can only get scattered fragments.

Lu Tianyu suddenly remembered the human laboratory he had seen before, and sighed lightly: "So that's the case!" ”

I found that many human beings have set foot in the building, and the facilities inside have no traces of moving, but now that I think about it, it is not that human beings have a good habit of protecting cultural relics, but they really dare not touch the equipment inside, once it turns into a handful of dust because of touch, even the last bit of research value is lost.

Lu Tianyu didn't have these scruples, he walked through the rooms, picked up the things he was interested in when he saw them, and most of them turned into fly ash in his hands, only a very small part, because of the use of extremely special material technology, it was barely retained to this day.

Lu Tianyu carefully picked up a small knife with a cold light from a pile of dust and fragments, and saw that the appearance was somewhat similar to a human scalpel, and gently scratched the ground, and the blade actually cut the ground neatly.

"This stuff is good! Collect a little more, and you can build a good cold weapon in the future. ”

Lu Tianyu walked around this medical center for half an hour, and there were no more than six things that could be seen and in his hands, including four pieces of equipment made of special materials, and Lu Tianyu was going to take them back to make a dagger to play with. The remaining two pieces are two special containers, one of which is placed in a limb of an alien creature, and the last container is an embryo, as for the origin of the things in these two containers, the auxiliary brain does not know, and the structure of it cannot be analyzed.

Lu Tianyu didn't care, and threw it into the storage space, moving towards the next goal.

As it approached the center of the main city, the destruction of the underground passage of the Ruins City became more and more serious, Lu Tianyu compared his own location, combined with the topographic map of the earth on the Internet, and found that the central area of the Ruins City actually overlapped with the Eye of the Sahara.

This discovery surprised Lu Tianyu a little, if you look down at the Eye of the Sahara from the air, you will find that this is a huge concentric circle landform, and it is also one of the top ten geological wonders of the earth. It reaches a diameter of 48 kilometers and an altitude of about 400 meters above sea level, making it fairly flat overall; It looks like an ammonite. As for the cause of the formation of the Eye of the Sahara, scientists on Earth speculate that it is the product of an extraterrestrial meteorite impact, and from the analysis of the geological structure, the formation time is exactly 90 million years ago.

This history is missing in the auxiliary brain, but Lu Tianyu guesses that it is very likely that this is left behind after the alien creatures attacked the earth.

The only good thing is that there is a 100-kilometer deviation between the Eye of the Sahara and the center of the Ruins City, but this is not a small deviation for the 200,000-square-kilometer main city of the Ruins City.

Lu Tianyu walked towards the center of the Ruins City, some of the underground passages were buried by quicksand, and he had to change directions, sometimes he couldn't see the next exit after walking for more than ten minutes, which showed how big the underground world of the Ruins City was.

After looking for the fourth medical center, Lu Tianyu was only a dozen kilometers away from the main city Zhinao Building in the data, and at this moment, there was a dense gunfire at the end of the passage in front of him?

"How can there be gunshots here?"

Lu Tianyu stopped, hid his figure, and walked in the direction where the gunshots came.

"The Taka people have been found here, and the first search team has requested reinforcements!"

This sudden encounter made Wang Qiang's nerves all excited, and as the human beings explored the interior of the Ruins City more and more, a group of creatures that had been hiding underground for an unknown number of thousands of years emerged and robbed the humans of the precious resources in the Ruins City.

It's not the first time that Wang Qiang has encountered a sneak attack by these Taka people in the Ruins City, these Taka people are extremely fierce, and a Taka can easily kill three specially trained warriors, but fortunately, the number of these Taka people is extremely rare, and at most there are only ten people at a time.

This time there were five Taka people, although the number was not many, but it was not something that Wang Qiang's ten-person team could kill.

In particular, the Taka people are good at hand-to-hand combat, and they rush into the crowd one by one without fear of death, and they can harvest a fresh life with a flash of the sword, which makes the human beings who are accustomed to medium and long-range combat suffer.

"Dense battle formation, don't let the Taka people get close!"

Wang Qiang roared loudly at the soldiers around him, and the six soldiers around him hid behind an object that looked like a carriage, blocking the crazy attack of the Taka people with crossfire.

The three pathfinder warriors were killed by the sudden appearance of the Taka people, which made Wang Qiang's search team completely fall into a passive beating situation, which is not the most terrible, the current situation is very unfavorable to Wang Qiang's search team, and he began to regret his carelessness at the beginning.

If anyone who discovered the city of ruins is the owner of this place, the people of Taka obviously discovered this place early and know more about the city of ruins.

But unfortunately, the Taka people are not a technological race, most of the Taka people have muscles in their heads, and it is not of much use to them to get the Ruined City, plus most of the creations in it have been damaged and cannot be used, and the Taka people are not very interested in the Ruined City.

However, the arrival of humans made the Taka people very unhappy, even if the city of ruins was a tattered, it would not be given to humans, and the conflict between the two sides inevitably broke out.

The bullet hit the armored Taka, and it didn't seem to have much effect other than stirring up a string of sparks that made the Taka hesitate a little.

"Change the armor-piercing bullets, aim at the eyes and mouth of the Takars......."

"Captain, we can't contact the headquarters, the current situation is extremely unfavorable for us, let's retreat first!"

In the underground passage of the Ruins City, this is the case, and the communication information will be inexplicably disturbed, and at this time, the headquarters cannot be contacted, and if you don't run, it will be a dead end.

But the problem is that Wang Qiang's team can't run if they want to, and the search team is now in a tall dome building, and the retreat when they come is blocked by two taka people, and if they want to rush over, they will inevitably suffer heavy casualties. And the passages in other directions are places that have never been set foot in before, and no one knows where they lead.

Seeing that the three Taka people were about to surround him from three sides, Wang Qiang gritted his teeth and said, "Come with me, even if we die in battle, we will be together!" ”

The four warriors began to retreat in batches towards the nearest passage entrance, while Wang Qiang led two warriors behind the palace.

The two taka men in charge of interception noticed that the search team had retreated to another passage, and also joined up with the other three takas, and gradually approached in the face of bullets fired by the search team.

"Captain! The taka people are catching up, you guys go quickly, I'll hold them back!" "A warrior gave up hope of retreat and volunteered to stay and hold back the Taka.

"No! Let's get out together, we can't leave you alone! ”

"Captain! Help me tell my parents that their son is not a bad breed, and if there is an afterlife, I want to continue to fight side by side with you! With that, the warrior took down the grenades from the other fighters, and prepared to blow up the entrance to the passage after the search team had withdrawn, preventing the Taka from continuing the pursuit.
