Just when Lin Ye made his decision, the Bird Civilization had already sent ten elders, and they brought a total of a thousand birds with them, and they were heading towards the Blood Moon Lake.

The large army of ostenths is slow, and it is estimated that it will take seven days to reach the dense forest area of Bloodmoon Lake.

On Lin Ye's side, the forging of high-grade alloys has already begun to be in full swing.

The previously discovered coal was quickly mined, and without it, the flame was not hot enough, and even steel was difficult to smelt.

The alloy bullets produced can easily cope with the birds, but the minerals needed are quickly found.

In addition to coal, the raw materials of alloys are extremely rare. And one of the raw materials of alloy bullets, chromium, is only a few pieces of ore scattered on the ground, without chrome ore, the musket has no bullets.

In addition to chrome ore, there are many more rare metal elements that need to be used.

Upon White Fur's search, it found that there were no rare veins around the Stone Tower. Lin Ye searched everywhere, but he didn't even find a shallow vein, only some scattered hematite. These iron ores are not of high purity, and when they are all refined, they can only make ten muskets.

Even if she has mastered the refining technology of high-grade alloys, she does not even have the fuel to make a fire, and she cannot refine alloys by relying only on the flames spewing from the ground.

The task of finding the veins fell on the heads of dozens of newborn flowers and birds. If you look down from the sky, you will see that in the top view of 360 degrees, each flower and bird is offset by nine degrees when it starts, as if a straight line is shot out from the center of the circle, and each straight line is nine degrees away from the other straight line, a total of 39 flowers and birds set off.

However, the birds and flowers did not find the veins at all, and they flew straight forward for ten kilometers, but they found nothing, except for grass under their feet.

When the birds and flowers finally got together to exchange their discoveries, they only found a small and pitiful copper vein in the northwest of the Shita District. However, the advanced alloy technology they have mastered hardly uses soft copper, and most of them use copper as a catalyst and play a role in the blending of alloys, and the amount used is not very large.

However, they found a lot of coal in the vicinity, and fifty troglodytes set out at once, carrying claws made of steel and baskets of yellow grass on their backs, which they used to hold coal.

If there are no resources, then everything is in vain. Of course, this is not to say that there is really nothing left in the Stone Tower District. It's just that the Stone Pagoda District doesn't have the resources they need, but there are still many resources buried that can't be used. For example, most of the plants in this meadow can be used to make medicinal herbs, and there are many gems and more minerals buried in the ground.

For example, Lin Ye had seen a black thing like soft mud on the ground before, which smelled fishy, and only then did he know that this was a very rare black mercury under the identification of the system, and he didn't know if it was mixed with something and became like this. This mercury can be used to create artificial rainfall, but unfortunately the Phoenix Civilization has not been recognized by the world, so it cannot obtain the permission to experiment with black mercury.

Without raw materials, weapons cannot be produced. Just when Lin Ye was at a loss, he suddenly remembered the Void Portal, there were no metal veins near the Stone Tower District, but there were not necessarily none near Sun City.

In front of the Dragon Tower, two dragon-blooded warriors guarded the Void Portal, which was the only fast passage between the Phoenix Civilization and Sun City, and the High Priest Kakat naturally sent troops to protect it.

Lin Ye walked out of the portal, and after saying hello to the Dragonblood Warrior, he found Gakat and asked if there were any ore veins nearby. And Kakat took Lin Ye to the sacrificial place of the South Temple. After talking to him, Lin Ye also learned that there was a metal vein wasteland in the south of Sun City.

Lin Ye soon flew out of the south gate, and the moment he saw the metal wasteland, Lin Ye's eyes widened excitedly. This area is a kilometer in circumference, and the ground is littered with ores of different shapes, which are of different colors, and although they are mixed together, they are still clearly recognizable. In addition to the ore on the ground, there is also a large area of metal ore exposed on the surface, and these veins are metallic and appear unusually thick in the sun. They occupied one-third of the entire ground, and the ore that Lin Ye could see with his naked eyes alone was enough for 80 troglodyte dragons to use weapons and ammunition. You can even craft more gear.

Lin Ye immediately told Bai Mao about it. White Fur quickly summoned nearly a hundred troglodyte dragons and got ready to go, and burrowed into the portal.

It would take a day to carry iron ore and other alloy ores from such a distance, and each troglodyte dragon could only carry a weight of about the same weight as it would at most, and it would take five days to come and go, and even through the Void Portal, a whole day would be spent on the way to the mine.

Of course, it is not possible to lay double rails with the steel mastered at the moment, but it is possible to start with single rails. With a stroke of inspiration, they forged arm-thick single rails, erected them to the ground, and made simple and durable minecarts out of steel and precision-cast gears. Minecarts can hold ten times the weight of a caveman at a time.

On the first day, the troglodytes didn't dig any ore, and they focused on setting up rails.

The next day, the caveman was still laying the rails. With the recruitment of gems, the half-dragons also joined the erection of the rails. The money-hungry half-dragon man immediately understood the intentions of the cave dragons, and began to lay the railroad tracks outside the city from the exit of the portal.

On the third day, the troglodyte dragon lays the rails into the passage inside the portal.

Laying rails in portals is a dangerous task, as in the void various Euglena insects pass by, and although they cannot pass through the fog that makes up the passage, they can laser at the creatures inside the portal. In order to prevent this, Lin Ye summoned the rock spirits to build a wall of earth along the mist in the passage, tightly isolating the passage from the void. Even if there were third-level euglenoids emitting destructive rays, the earthen wall would be able to hold out for a while, giving the caveworm and the rest of the group time to escape.

A mining truck carrying a cavedragon departed from the Stone Tower area, made its way on the relatively smooth subway tracks, and burrowed into the Void Portal.

On the fourth day, the caveman brought back all the ore and began smelting the ore in full swing.

At the same time, Lin Ye was standing on the edge of the Blood Moon Lake at the moment, and there was a cave on the shore of the lake that he had just dug out, and there were five first-level euglena clustered in it. Around the cave are the ashes of the birds. The remnants of the spirit attached to the ashes are absorbed by the euglena. The morphology of these first-order euglena began to change. Their bodies swelled, and the tentacles clinging to the sand re-lifted.

They quickly moved to Level 2, and three minutes later, Level 3. At this moment, Lin Ye stretched out his claws and grabbed them and threw them into the shelter area of the Phoenix Civilization.

Smoke emitted from the bodies of the five third-level euglena as soon as they came into contact with the shelter area, and they squeaked in horror while immediately forming a thin film on the surface, isolating their bodies from the outside world and briefly falling into a dormant state.

This is the ideal hometown ability of the Phoenix civilization, which can kill second-level and below euglena, and has a suppressive effect on high-level euglena. Although the third-level euglena can avoid death, it is also unable to move at all under the suppression of the shelter area.

The Phoenix civilization's sanctuary area is just right to restrain the euglena, and if other civilizations encounter these euglenae, they will inevitably face a disaster. And they will become Lin Ye's help, and they will officially enter the battle.

In these seven days of peace, the speed of development of the Phoenix civilization can be called a miracle.

Although the ore veins that can be mined are far away from the stone tower area, this cannot stop the determination of the flowers and birds. Based on the blueprint of the steam power technology they had obtained, they began to study how to put it into practice. Lin Ye's experience has helped them immensely.

"First of all, we have to make the corresponding parts, vices, screws, and wrenches. Lin Ye carefully taught his subordinates and took the lead in demonstrating how to refine tools with flames. These tools are all strange in front of the flowers and birds, but they are extremely familiar to Lin Ye, and even make Lin Ye nostalgic for being a human.

I didn't expect that one day, I would be able to reproduce the industrial civilization of mankind step by step...... Lin Ye sighed in his heart. This is only a small step to open up industrial civilization, but it is indeed a big step for the Phoenix civilization. Driven by Lin Ye, the steam engine can be made quickly, although the power of the steam engine may not be as strong as the power of the Allosaurus, and it cannot be put into practical use on a large scale for the time being, but it can already be used on a small scale, such as the minecart on the railroad track can soon be powered by steam, using coal as fuel.

Every time he thought of this, Lin Ye couldn't help but sigh again. The Phoenix Civilization has been established for a period of time, why can't it develop technology? Lin Ye's heart was a little unconvinced, the path of human industrial civilization had been nakedly placed in front of Lin Ye, but as long as the world did not give the Phoenix Civilization recognition, then this road would be sealed in front of Lin Ye, out of reach.

This industrial road was nakedly tempting Lin Ye, scratching his head towards Lin Ye, but Lin Ye could only stare at a pair of eyes dryly, and he couldn't do anything.

"Why does it have to be recognized by the world, which unit stipulates this rule!?" Lin Ye suddenly felt resentful in his heart, and muttered to himself indignantly.

The system unexpectedly did not answer Lin Ye's question, and it remained silent and did not say anything.

Grumbling certainly won't solve the problem. Since there was such a restriction, he had to grow within the limit before Lin Ye didn't have enough strength to develop enough to break this restriction.

Lin Ye began to think: "How can I gain the recognition of the world?"

He paced from side to side, scratching his head.

The system says that in order to be recognized by the world, the entire civilization must master the knowledge of technology, and at the same time use the power of faith to extract this knowledge from the minds of all members to form a physical blueprint of technology.

As long as there is this technical blueprint, it can be recognized by the world.

This is not something that can be achieved overnight, and it requires the joint efforts of civilized members. It is necessary to emerge talented members such as scholars, scientists, architects, artists, etc., and of course, these members can also be spurred out by the power of faith.

This is the original function of the power of faith, and the totemic spirits can use the power of faith to modify the bloodline of members, making them more adaptable.

Lin Ye came to a cave dragon's dinosaur egg, this dinosaur egg was as thick as Lin Ye's calf, just conceived from the body of the cave dragon, croaking to the ground for less than an hour, and soon it could break out of the shell.

The skyrocketing number of civilization members has led to the rapid growth of the power of faith, and in just five days, Lin Ye already has more than twenty faith rings, which is equivalent to the savings of an ordinary Phoenix civilization for twenty days. Lin Ye injected the Ring of Faith into the eggshell. The soft ring of faith was silent, and the dinosaur egg shook quietly. Then the eggshell cracked, and a young caveman poked out of the eggshell.

The cave dragon cub's eyes were full of curiosity, and its body was covered with a yellow shimmer, as if to show its noble status.

On its forehead was a mark that had not yet been formed, and milky white marks were intertwined, as if waiting for Lin Ye to shape it.

"The cave dragon cub has the status of royalty, and his intelligence has been greatly improved again, and he has extremely strong learning ability and innovation ability. After determining the symbol on the forehead, it is possible to become a particular leader. ”

"There are currently three types of leaders to choose from: Elders, Scientists, and Military Strategists. Level 2 civilizations can only accommodate a maximum of twenty leaders. The more elders there are, the more stable the civilization will be, and it will not be easy to split from within, the more scientists there will be, the more opportunities the civilization will have to innovate and create new technologies, and the more military strategists there will be, the stronger the horizontal combat power of the civilization will be, and it will not be easy to be destroyed by external aggression. ”

Lin Ye calmed down, pointed his paw at the cub's forehead, and after hearing the choice of the three leaders, thinking of the flock of birds that was about to be overwhelmed by the army, Lin Ye quickly determined the cub's military strategist's identity.

The vague mark immediately changed to the pattern of a musket, and the cub's claws began to grow sharp claws rapidly, and the smooth skin began to grow a thick dragon's blood armor.

"Your name is Fire Claw!" Lin Ye said.

After hearing Lin Ye's name for it, Fireclaw immediately happily spun around in place a few times and screamed happily at the same time.
