A bright sky is cloudless, and occasionally a flower or bird flies through the sky. Each bird carries a basket of delicate gemstones, beautifully carved from a gem mine found nearby.

After finding that it could not defeat the Phoenix civilization, the Bird Civilization chose to retreat. The other four alien civilizations did not run into the realm of the Blood Moon Lake again.

Although the dozens of third-level euglena bred by Lin Ye did not come in handy in the Bird Civilization, they could be used as counterattacks.

The flower and bird Xiaoliu volunteered to fly north with a basket of third-level eye worms. It was given the ability to strengthen its muscles by Lin Ye, and it was able to lift ten third-level euglena in one go, and it could fly thousands of miles in a row before the euglena regained its mobility.

Bai Mao had already learned the specific location of the main city of the bird from the mouth of the captured bird, and these eyeworms would be released into the main city of the bird by Xiao Liu. They will destroy the Bird Civilization from within.

After Xiao Liu left, the flowers and birds carrying the gems on their backs chirped and lined up into the void portal. The vortex of the portal is constantly shining, and the entry and exit of flowers and birds will consume the energy of the Void Iron embedded in the portal. In the course of a month, the energy of the Void Iron had been consumed to less than a third of what was left. Once the energy is depleted, the Void Portal is deactivated.

Cave dragons and birds had to make the long journey to Cité Soleil.

A large number of gems were put into Sun City in exchange for a large reserve of food. These foods were used to satisfy the rapidly expanding dragon and bird mouths of the Phoenix Civilization. Some of the half-dragons even passed through the portal and decided to settle in the Stone Tower area. They soon became a part of the Phoenix civilization.

The Blue Spirits near the shallow waters have built a small viscose city, and their numbers have rapidly increased to more than 140 individuals.

More than a hundred Blue Water Spirit warriors have already appeared in larger Blue Water Spirit warriors, and after they became warriors, they immediately joined the army of the Phoenix Civilization excitedly.

These Blue Water Spirit Warriors have a soft gummy layer that can withstand attacks that many troglodytes can't stop. They were hired by Whitefur as storehouse keepers. These blue water spirits happily jumped on the ground several times.

The three Tyrannosaurus rexes of Guishun were being transformed by Lin Ye, and their bodies were soon covered with a heavy layer of dragon blood armor, and two of them had already gained muscle strengthening abilities with Lin Ye's help. Once these huge tyrannosaurs have the ability to treat the caveworm warriors, the combat power they exert is far beyond the ability of the caveman warriors.

The intelligence level of these tyrannosaurus rexes has also begun to improve significantly, and they can already begin to speak, and even express their joys, sorrows, and sorrows in words. Although there is still a long way to go before they become proficient in the use of Chinese characters, these tyrannosaurs have undoubtedly become the most elite warriors of the Phoenix civilization, under the direct command of Fire Claw.

However, the shackles around the neck of the Tyrannosaurus rex could never be unraveled, and this shackle made of high-grade alloys used the same technology as the remains of the Blood Moon Lake, which enclosed the neck of the Tyrannosaurus rex so tightly that even Lin Ye's power could not tear the shackles apart.

——————————

The gems brought by the Phoenix civilization began to affect the economy of the Sun Dragon civilization. In the past month, the total weight of gems obtained from the Phoenix Civilization has exceeded the total number of gems mined by itself. The gem mines of Cité Soleil are mined by priestly overseers, and the amount of gems mined has been very stable. The gems of the Phoenix civilization began to pour in, disrupting the plans for the sacrifice.

If the food and materials produced are not available, it will definitely lead to the depreciation of the gem.

Although the speed of development of the Phoenix civilization is obvious to all, the economy of the Sun Dragon civilization has begun to reach the brink of collapse. If a little bit of force is not taken, the solar dragon civilization will collapse due to the influx of gems.

The easiest way to change this is to switch to a new type of currency that no longer treats gemstones as currency.

However, the half-dragon people did not know what kind of currency should be used to circulate in the solar dragon civilization without hindrance.

Lin Ye had long had the idea of switching to a new type of currency, and Lin Ye knew in his heart that only real money was the best hard currency in this world.

After the Phoenix Civilization entered the second level, the Sun Dragon Civilization, which was still at the first level, had become a vassal of the Phoenix Civilization and was a part of it. No matter which one collapses, it will be bad for Lin Ye.

"Do you want to turn on the function of detecting silver?" the system prompts: "It costs 2,000 points of natural breath to activate this function." At that point, the host's forensic eye will have the ability to detect silver veins. ”

"Yes!" Lin Ye immediately nodded and said.

As soon as the words fell, Lin Ye's eyes immediately poured into a new light, slightly shining with a silver-white light.

"After receiving the host's answer, the host's identification eye level is being increased to C+. ”

Lin Ye opened his eyes, and his eyes looked unusually bright in the night. In Lin Ye's field of vision, crystal points of light appeared on the ground, these white points of light were all silver elements scattered in the soil, their number was very small, even if all the land within a radius of kilometers was filtered and the silver in it was precipitated, it would only be about a kilogram in weight.

Lin Ye's right wing had regained some consciousness in a month's time, and he was able to lift some heavy objects, and after switching to the Honghu form, the power exerted by his right wing was no different from usual.

He was hovering in the air, and there were no silver mines nearby.

An image suddenly appeared in Lin Ye's mind, he remembered the cave under the shallow water, he remembered that there was an abandoned gem mine in the complicated passage of the cave, and the valuable gems of that gem mine had basically been taken away by Lin Ye, but Lin Ye also found a piece of silver ore in the abandoned mine. Maybe it's a silver mine.

Lin Ye excitedly moved away from the stone slab on the edge of the clear spring, and immediately jumped down from the cave. After an hour, Lin Ye returned to the gate of the abandoned mine.

The radial black liquid lay at Lin Ye's feet, and the black liquid had dried up to the point that only a layer of gum remained. Lin Ye's brisk running disturbed the air in the cave and alarmed the mysterious creatures in the cave.

A rough gasp came from behind Lin Ye, and a mutated caveman dragon with a strange nose was running towards Lin Ye quickly, stretching out its corroded claws and muttering at the same time.

The mutated troglosaurus in the cave was not swept away, but has survived until now, its lower body has turned into a black pulp, and only the outline of a pair of thighs is faintly discernible under the black mud. The speed of the mutant cave dragon was extremely slow in Lin Ye's eyes,

"It's too slow!" Lin Ye turned to the side slightly, and the mutant troglodyte dragon pounced, its lower body unsteady on its feet, and fell into the mine in front of it.

Lin Ye sighed and said to himself, "In just a few months, my strength has become so much stronger than before. If it had been months ago, I would have even dodged its attacks, carefully slipping out from under its nose. ”

The mutant cave dragon, whose body was close to collapse, was almost smashed directly into meat sauce, and it stretched its neck and roared loudly at Lin Ye. Lin Ye immediately switched to the form of a bird, spread his right wings, and danced a strong wind below. This strong wind, which did not rely on any spiritual power, surpassed the storm created by Lin Ye as a Qingluan form in a short period of time.

The strong wind swept through the entire underground mine, and the mutant troglodyte dragon that bore the brunt of it was like a jelly stuck to the ground, quickly blown away by the strong wind, and the black body fluids on its body were separated from the skeleton of the troglodyte dragon because of the lack of adhesion to the body, and were sprinkled everywhere.

Lin Ye switched into the form of the red wind, and at the same time unleashed a fire, burning all the black bodily fluids around the mine.

The mutant cave dragon that could once force Lin Ye into the path to escape, but now he can't even touch a single feather of Lin Ye, and has become the nourishment for the flames to burn.

The strong wind blew all the floating soil on the mine clean, and a silver-white vein appeared in front of Lin Ye's eyes.

A suspicious black shadow was also accidentally exposed in front of Lin Ye.

"Found a warm-blooded creature!" the system suddenly prompted.

A shrill cry came out of the dark shadow's mouth, and it immediately burrowed deeper into the hole. Although the time he was exposed to Lin Ye's eyes was only a short five seconds, Lin Ye began to see the front of the black shadow clearly.

The latter has six palms and dark eyes, as if it can absorb all the darkness, it is like a large spider made of muscles, with six palms touching the ground. On the skin there are dense brown bristles. These bristles are able to clearly detect the movement of the surrounding air.

"In the identification of species, black-faced fierce spiders, mammals. The specific information is unknown, and more clues are needed to be able to determine. Warning, the black-faced ferocious spider harbors great malice towards its host. ”

I didn't expect to find a mammal in the dark underground cave. Lin Ye's heart was vigilant, and his feathers exploded slightly. This black-faced fierce spider had been hiding in the mine from the beginning, but Lin Ye hadn't noticed it at all. Thinking of this, Lin Ye couldn't help but feel a little jealous.

There are many secrets in this world that have not yet been discovered. Especially in this mysterious forbidden land of the Blood Moon Lake realm, it is not surprising that anything can happen. Lin Ye took a deep breath and jumped in front of the silver mine. This piece of silver ore stretched for hundreds of meters in Lin Ye's opinion, and stretched to a depth of hundreds of meters. The silver ore buried in the ground also glows white, the bright white light is very dazzling, and the purity of the silver ore is very high, even so pure that it does not look like a naturally formed silver mine from the outside world.

"Host, this silver mine is expected to be able to mine thirty tons of silver, which can already be used to recover the gems circulating in the Sun Dragon Civilization and Phoenix Civilization and circulate in the market as an alternative currency. ”

Lin Ye nodded.

A black dot suddenly appeared at the end of the white light, Lin Ye's eyebrows furrowed, and he saw the black dot flash in the white light, and at the same time, there was a dull rumbling sound from the ground.

The rumbling sound never stopped, as if something was digging through the earth, constantly carving out new passages deeper into the earth.

"But I advise the host to abandon this silver mine. The black-faced ferocious spider had been hovering around, and if the host's people encountered it, there was a chance that their lives would be in danger on the ninth floor. ”

"You're right, but I have a better way. ”

Lin Ye's eyes were calm, staring at the rumbling ground and said, "As long as we kill that black-faced fierce spider, this silver mine will belong to us." ”

The gems circulating between the two civilizations are not a good currency after all, after all, the number of gems is very large, and the elements that make up gems can be seen everywhere, and as long as the technology develops in the future, even artificial gems can be made. However, gold and silver are quite rare, and the total mass of gold and silver has hardly changed since the time when the universe was formed, and they are also very rare elements in the universe.

In order to carry out the currency reform, Lin Ye is determined to get the silver vein in front of him.

Lin Ye burrowed into the cave dug by the black-faced fierce spider, and he carefully inspected the inner walls of the cave, and found that it was full of marks left by scratching with human hands.

"Human hands?" Lin Ye muttered to himself, his mind flashing the vague appearance of a black-faced fierce spider, its six arms indeed looked like human hands.

The black-faced fierce spider dug very quickly, and in just ten minutes, it dug a passage of nearly six hundred meters. Lin Ye walked along the passage, in the dark environment, Lin Ye's eyes were as bright as day, and the picture in front of him seemed like daytime to him. He jumped out of the finish line and landed underneath a very wet underground.

The soil under his feet was very soft, the cold groundwater was up to Lin Ye's knees, and the exit above his head looked very old. The white silver veins stopped extending above Lin Ye's head. The water vapor here is so heavy that every big breath is like breathing in water.

The cavity is surrounded by excavated passages, some of which are very old and even half collapsed, while others have not been dug out for a long time, and the soil is very fresh.

At the very front of the narrow hollow, there is something resembling a metal can. The metal canister was the size of Lin Ye's two heads, just enough to hold an adult. The hatch of the metal canister was twisted open and torn in half. A large amount of groundwater has accumulated inside the tank, and it has been half buried by mud. The top of the metal can pressed against the heavy layer of soil overhead, and it was it that created a natural cavity that allowed Lin Ye to stand.

There are still some strange red substances left in the metal cans, and a large number of unknown mysterious instruments are placed in the hatches, all of which have been rendered dead and in tatters. It looks like it's been around for at least thousands of years, if not longer. Its outer shell is made of high-grade alloys, which are even more mysterious than high-grade alloys.

Lin Ye stretched out his wings and touched the twisted hatch, and a wound was immediately cut. A drop of blood fell on the cold hatch, staining the groundwater inside the tank red.

"Host, it's a Jurassic creation!" the system shouted.
