Lu Yao's perspective cut into the boundary dimensional space, and saw that there was a simple dashboard shaped like a compass on the right.

In the center of the dashboard is a green dot with several names crammed together: [Fragment World Unnamed], [Cloud Temple], [Ghost World], [Bamboo Reed Country], and [Toaster's Banquet Bird].

As the axis, the green cluster is the annular group around the vortex world.

There is only one hand on the dial, pointing northeast.

That is to say, Ryujuku is on this route.

Since changing the operation of the vortex world, Lu Yao's biggest trouble is the lack of maps, and he can only wander aimlessly in the crawling area, and what he can encounter depends purely on luck.

Since hitting the road, his only gain is that he has captured two kingdoms of God and can experiment with various ideas.

Now that we know the approximate location of Longsu, we have a relatively clear set sailing coordinates. As long as you sail all the way in this direction, you will find the passage world that connects to the dragon house.

These passage worlds are either vassals of the dragons in the crawling zone, or some gods who are friendly with the dragons.

Due to the deterrent power of the dragons, the passage world is usually a relatively safe area, like a small harbor in the crawling area, maintaining a relatively stable environment.

Lu Yao made a two-handed plan.

If the passage world is intact, you can still enter the Dragon House, and it is logical to let the silkworm cong and the dragon of the dark sun under your command visit, and there is still a chance to make a deal.

If the passage world has been destroyed, the passage world itself is also a kingdom of gods - there are still three nails in the rotten ship, and there are still a lot of almighty stones in the gravel world like the banquet bird, not to mention the former kingdom of God.

Now that the development of the Banquet Bird is also coming to an end, it is time to find the next project for the Wujiwang team.

After sorting out the pros and cons, Lu Yao set sail and turned around, pointing the vortex world directly at the nearest Longsu Passage World.

In the crawling area, each world moves very slowly, and it is impossible to reach its destination for a moment.

Lu Yao didn't want to waste his faith to speed up, so he let it go first.

He switched back to the Yao world and first solved some of the troubles that had accumulated over the years in the world.

……

For quite some time, Lu Yao has paid attention to the outer circulation of civilization, which does not mean that the internal circulation is smooth. It's just that the internal foundation is relatively solid, so there is no fundamental problem.

The Yao people have a long-term hidden danger that has lasted for many years.

The new population is small.

After two epoch updates, the population of the Yao people has doubled consecutively. However, the initial population base of the Yao nationality was very small, resulting in the total number of Yao people still less than 500,000 people.

This point made Lu Yao attach great importance to it.

It stands to reason that now that the Yao population is not short of food, meat, eggs and milk are also guaranteed to a certain extent, and the urban environment in which they live is constantly improving, why can't the fertility rate be raised?

He used the [Wishing Star] to read the living conditions of the pixel villains, questioned the apostles, and looked through various data and descriptions in the background of the world...... Only then did I initially understand the reason behind it.

Two factors.

One is the environmental impact.

At present, the Yao people have only experienced the second age. The first era was relatively comfortable, the second era of poison increased, the extreme weather led to frequent natural disasters, and the continuous growth of supernatural creatures, so that the mortality rate of the Yao people increased to a certain extent.

The second is human selection.

The overall development of the Yao clan changed after the appearance of potions and ghost armor, and it was no longer a path from farming and animal husbandry to the refinement of urban handicrafts.

On the fork in the road of civilization, the Yao people entered the field of transcendent technology, which had no precedent to follow, and also brought a series of unpredictable follow-up developments.

The first is that the number of transcendent human beings of the Yao tribe has increased, resulting in more intermarriages between ordinary people and transcendentals, and it is more difficult for transcendents to reproduce than ordinary people.

In addition, the Yao people are now accustomed to using potions to cure diseases, and use potions as tools. But after all, the history of potions is too short, and the side effects are difficult to assess, and the Yao people have physiologically endured certain pressures and influences.

The fertility rate has fallen.

It can only be said that there are both objective reasons and subjective choices.

Lu Yao's method is to encourage childbearing and introduce immigrants.

Strategies to encourage childbearing have had good results in several wealthy cities. In particular, Yancheng and Wuda City, these two cities have given high incentives, but they have pulled a lot of people from other cities.

In general, there is a role.

The introduction of immigrants consists of both internal and external parts.

Internal migration mainly refers to the scattered mountain people, islanders and aborigines in the Yao world, who did not settle in the Yao cities for various reasons.

At present, the immigrants only recruit laborers from the ghost realm and the Zhulu Kingdom, and temporarily settle them in Shacheng, so that this group of people can participate in the construction of Shacheng and slowly become Yao city residents.

All of these strategies have a visible positive effect, but further population growth will take time.

In the simulator, pixel figures look like mass-produced NPCs, but underneath these pixel images are low-dimensional beings.

Life has its own choices.

What Lu Yao has to do is to give them a better environment, which is also the rule of the gods that he has always adhered to. Don't turn the pixel world into a canning factory, just pursue enough quantity and good enough data.

In addition to the demographic problem, there is another pain point.

【Brass Furnace Dragon】.

The Yao civilization is trying to promote transcendent technology, so it will definitely need more diverse and abundant high-quality materials.

Lu Yao pulled a list of materials, which contained several candidates for gifts: rubber trees, locust trees, coconut trees.

Rubber trees produce latex, which is natural rubber after drying and solidifying.

The locust tree is of excellent quality and can be used to make ships, sleepers and vehicles, and the seeds can be extracted for oil and secrete resin.

The coconut fruit of the coconut tree is a high-quality fruit, the coconut flesh is edible, and the coconut fiber can be made into durable fabrics such as brushes and carpets.

Lu Yao's heart is inclined to rubber trees.

Rubber is the basic material of industry, and brass furnace dragons can be used no matter what.

If you need this kind of thing, you still have to ask the person concerned.

"Gods, all the gifts you have given are great gifts......

The Apostle Philus was careful in his words: "The kind of material you said that is waterproof, not afraid of fire, and resilient is actually already available to the Yao people. ”

Lu Yao has a question mark, can you all make this up?

"It's [Black Black Mud]."

The Skeleton Man explains: "Black clay has excellent waterproof ability, it can be shaped and bonded with a little heat, and it will retain a certain amount of flexibility after solidification, which is reliable and durable. These are the words of the people of Uzi who have been experiencing for many years. ”

"When the White Castle first designed the [Brass Furnace Dragon], it was considered to use black black mud for partial wrapping, and even built some soft passages to allow the blood of the artificial dragon to circulate."

"But there was a problem that was not solved at that time, that is, how to make black black mud fireproof."

When it comes to professional issues, Fellers spoke in detail: "It wasn't until half a year ago that an engineer named Tieyang in Yancheng finally found a way. ”

He mixes black mud with borax to create a shiny fireproof layer that is also resistant to abrasion. This major improvement has completely turned black clay into a high-grade material that can be used in a wide range of applications, not only for brass furnaces, but also in other engineering and foundry......"

Lu Yao is a little blind.

This macho man named Tieyang, why didn't the simulator remind him at all?

“…… Tie Yang is now a tenured scholar at White Castle, where he continues his research on advanced materials. Such great scholars are still emerging, and the atmosphere of creation and invention of the Yao people has never been stronger. Philus said happily.

Lu Yao found that Tie Yang in the White Castle.

Engineer Tie Yang is 72 years old, and only the backstage can find out his detailed experience. He began as an apprentice blacksmith and became an engineer after graduating from the Faculty of Engineering at the age of 37.

His personal history is almost entirely blank, apparently considered unremarkable and unworthy of record, except for the transformation of black mud.

At the age of 72, Tieyang finally discovered the use of borax.

The borax-modified black mud has been turned into a high-level alternative to natural rubber, a renewable material that has been proven by the Uji people for many years. The White Fort is now constantly urging the Prophet Black Forge to produce a large amount of black black mud.

Lu Yao added a point to Tie Yang and asked him to upgrade to LV10, which might extend his lifespan.

"Thank you, Yaoshen...... Thank...... Thank you for your grace. The old engineer sat down on his knees in fear, and kept expressing his gratitude to the gods for their blessings.

Lu Yao sighed.

The Yao clan is now too competitive internally, and the invention of bored black black mud is not enough to surpass the same group, and it is impossible to trigger the transformation mechanism of heroes and prophets.

Apparently there are other inventors of the same level who have made similar contributions.

Lu Yao suddenly felt a burst of emptiness.

I, the god, can't find a place for a gift.

Forget it, I'm going to give you coconuts.

He grabbed a green coconut on the table.

Suddenly, Lu Yao thought that the gift was the icing on the cake for the Yao world, but the Shacheng side might be a charcoal in the snow. Yunzhong Temple needs more resources to tilt and support.

So Lu Yao put down the coconut and looked at the cactus in the potted plant on the table.

"Xiaohuo, peel a coconut for me."

"Yes, Kami-sama."

The cactus ball stood up from the potted plant and ran to the kitchen with the coconut on his shoulder.

Lu Yao found a pair of chopsticks and took out the cactus next to the potted plant - this was originally used to camouflage and cover Xiaohuo, he deliberately bought some cacti and Xiaohuo to make a bunch.

The cactus was given to the temple of Sand City.

Soon, two cacti grew outside the temple.

The gods have given the first gift to Sand City, which has excited the inhabitants of Sand City large and small.

"The Grace of the Gods!"

"The gods have blessed Sand City!"

"This is a gift and life from the god Yao, we must protect it!"

"Cactus, we're going to plant a lot of cacti."

"Everybody's in action."

Mayor Slemod's doppelganger began to lead the crowd and began planting cacti together.

Lu Yao touched his chin.

It's not enough.

In an extreme environment like Yunzhong Temple, ordinary cacti may not be able to bear it, so they have to be given a boost in strength.

Lu Yao clicked on the Golden Field and opened the [Tree of Creation].
