For the remaining three days, the wandering Black-Ringed Worms came close to possessing the shallow waters and stone towers of the buildings on several occasions. Once discovered by them, then Lin Ye's Phoenix Civilization will be completely exposed in front of their eyes.

However, any black-ringed worms that are close to this area are closely monitored. As long as he found a lone black-ringed worm, Lin Ye would not hesitate to attack it.

Lin Ye had never shown mercy to his subordinates, and every time he attacked, he used a powerful Red Spirit Fire, and he would never give the Black Ring Worm any chance to escape and beg for mercy. The spirit base that can be used once a day is beneficial at this time, plus Lin Ye's two feathers that can turn into red spirit fire at any time, in three days, there are already five black-ringed worms buried under Lin Ye's hands.

Among them, there was a worm with four rings on its body that was very powerful, and after it was hit by Lin Ye's red spirit fire, it still had a breath, and even wanted to launch a counterattack against Lin Ye. However, it was already seriously injured by the red spirit fire in its body. Its body sometimes becomes transparent, sometimes it becomes a physical entity, and it seems to have the same ability to travel through the void as an eyeworm. However, these were not difficult for Lin Ye, Lin Ye used the flame claw to cut its belly, and a large number of gems poured down from its stomach with a crisp ding sound. And the worm finally died on the spot.

After killing the black-ringed worm, Lin Ye found some gems in the worm's body that were more precious than those carried by other worms. The hairy rats transferred all the gems inside the worm's body to the storehouse, and the five black-ringed worms provided the gems in good color, each of which was the size of the hairy rat's body.

So that's it...... Lin Ye muttered to himself, and he immediately figured out the purpose of the Black Ring Worm's exploration in the Blood Moon Lake, which was precisely to collect the gems underground.

Among the five alien civilizations, the Black-Ringed Worm is much richer than the others, and although they are the weakest of the alien races, they are also the most daring, using their spirit of exploration to find the gems underground, and then trade these gems with other aliens in exchange for food, housing, and other benefits.

They may not have as many as Lin Ye thought, and all their actions are to get more gems. But we have to admit that this kind of individual greed comes together and becomes the driving force for the whole civilization to move forward.

"My lord, we found a piece of black iron in the worm's belly. The white hair flew over and said to Lin Ye.

It was originally a meteorite that fell from space, but was swallowed by the Black-Ringed Worm after falling to the ground. The meteorite copper was pitch black, and although it was unknown how many years it had been swallowed into the worm's stomach, it still revealed an eerie aura. A few curious hairy rats were surrounding the meteorite, as if they were looking for something, and when they saw Lin Ye flying over, they immediately moved out of the way.

Lin Ye stretched out his paws and touched the meteoric iron, and the place where he touched it suddenly felt cold. There seemed to be a mysterious lifeform hidden inside the meteorite, and Lin Ye used his forensic eye to see a well-defined yellow light and shadow in the very center of the meteorite. It was wrapped in meteorite and motionless, as if it had fallen into a deep slumber.

The system that had been concentrating on the study of the Void Core suddenly appeared in Lin Ye's mind and said:

"It's a void creation!"

The system seemed to be very concerned about the meteorite iron obtained by Lin Ye, and even no longer seized the time to study the Void Core, but began to analyze the meteoric iron: "Void Iron, brought by eyeworms above level four, can replace the Void Core, so that the eyeworms can maintain contact with the Void at any time, generally speaking, the Void Iron will disappear after the death of the Void Worm, but this Void Iron has not disappeared." ”

At the core of the Void Iron is the natural breath that has not been transformed into an entity, as long as Lin Ye breaks the shell of the Void Iron, he can obtain a large amount of natural breath. However, Lin Ye didn't know what his next advance condition was, he had already absorbed a large amount of natural aura, but his body hadn't changed at all. It seemed that the breath of nature was no longer one of the only conditions for him to advance.

"Void Iron can be used to craft Void Buildings. It is not dangerous. There is currently no use for the host and the Phoenix civilization. The system said, then disappeared from Lin Ye's mind and continued to study the Void Core.

Lin Ye ordered Bai Mao to put the Void Iron in the repository along with the gems.

Two more days passed, and Lin Ye replenished the resurrection feathers on his body to keep himself in the strongest state. In the early hours of that morning, before dawn, an earthquake came from the side of the Blood Moon Lake. The surface of the ground beneath Lin Ye's feet began to shake violently, and the ground cracked, revealing an unfathomable crack that seemed to fall into the abyss along the crack.

With a long roar, the relics of the high-level civilization at the bottom of the sleeping Blood Moon Lake finally opened.

The earthquake lasted for half an hour, and the alien team at the northern end of the Bloodmoon Lake had already begun to act. Led by giant bats, they formed a team of two hundred people and marched mightily towards the Blood Moon Lake to the south.

The Black-Ringed Worms who had left the team also gathered, and the Worm Leader counted the number of worms that had gathered, only to find that they were six fewer than when they had just arrived. That's a tenth of the total number of the entire team.

The living black-ringed worm spat out the gems it had collected to the ground, piling them up into a small mountain. They dug a deep hole and buried the gem mountain in it.

The worm leader was surprised and asked, "How can there be so much less?"

The worms all shook their heads, saying that they didn't know why this happened, they all acted alone, and after setting off alone, they never saw their dead companions again, and naturally they didn't know what the cause of their death was.

"Forget it!

The worm leader didn't think much of it, and immediately led the team to follow the alien team far behind.

Previously, more than half of the water in the Blood Moon Lake seemed to have evaporated overnight. In its four directions, there are still four small lakes in its southeast, north, and west, and the ruins in the center are standing on high hills, all of which are exposed to the water. A large number of aquatic plants lay on the ground weakly because they had lost their water, sinking into the muddy bottom of the lake.

The kilometer-long complex of ancient buildings reveals a metallic color. In the crevices of the building, a large number of aquatic plants have taken root here, and they slump on the walls of the building, covering the metallic color of the building.

After the lake receded, the complex finally showed its original form. Together, they form a magnificent city, with different buildings in each area.

In the very center of the city was a towering bell tower, which Lin Ye had seen before. The door of the bell tower was slightly open, revealing a deep darkness through the crack, making it almost impossible to see what was hidden inside.

Four wide straight paths radiate from the foot of the bell tower, each large enough to accommodate hundreds of people walking side by side at the same time. On both sides of the road stand low construction areas, most of which are closed gates, and all kinds of aquatic plants are seamlessly drilled, and even grow in the cracks of the road floor.

The city looks much smaller than the City of the Sun and the Soft Rubber City, but it has an eerie atmosphere, as if the city is just the tip of the iceberg of ruins in the outside world.

Outside the city, in four directions, a thick metal wall encloses the city, leaving only a closed gate to the north. Hundreds of circuits spread out from the center of the gate, flashing with a purple-blue light, and seemed to have considerable vitality.

The entire city stands in the very center of the Bloodmoon Lake, on top of a hill rising from the bottom of the lake. Outside the city walls, the lake was covered with soft mud, and there was hardly any place to walk.

Although the lake has completely receded, the no-fly zone is still there, as long as it is in the no-fly zone, all flying creatures must be unable to fly, and even the jumps of some animals will be pulled down by a force of gravity. A carnivorous pterosaur was flying over the ruins, and unaware of the danger of the ruins, flew into the no-fly zone of the ruins. As soon as its head touched the edge of the no-fly zone, it was grabbed by a mysterious force and dragged its claws towards the ground.

The pterosaur screamed, and in an instant, it fell down from a height of thousands of meters. The soft mud of the lake is like a hard concrete floor in front of high-speed moving objects. The pterosaur couldn't even flap its wings, and was directly smashed into a piece of meat sauce. The aquatic plants that had been weak before immediately changed their appearance, and the aquatic plants that were close to the meat sauce suddenly raised their heads and frantically rushed to the meat sauce.

The tips of the aquatic plants are like stinging mouthparts, as sharp as steel needles. They sucked frantically as they stabbed at the bolognese, and their bodies grew brighter, leaving an eerie blood-red color on the leaves.

Around the perimeter of the magnificent complex, aquatic plants in this camouflage are everywhere. And the no-fly zone of the ruins also shrouded hundreds of meters outside the ruins city.

Half an hour after the earthquake, Lin Ye had already come to the top of the Blood Moon Lake, and he stood quietly on a stone at the bottom of the lake, keeping a certain distance from the surrounding aquatic plants. These aquatic weeds seem to have undergone a high-intensity mutation, they usually camouflage, and when a prey passes by, they will immediately attack them in groups.

Lin Ye once found a tough yellow aquatic plant by the lake that could be used to weave into a rope, which was a degraded version of these blood-colored aquatic plants. They are tough and sharp, and even now, cavemen occasionally use these aquatic plants to weave baskets and ropes.

Lin Ye witnessed the whole process of the death of the pterosaur. He swallowed a mouthful of saliva and couldn't help but shrink his neck.
