The sky was filled with smoke and dust, and the rich rock energy flowed above the mountain.

Boom boom boom~

Although the strength of each rock spirit is different, the power of the moves cast is also different, which also leads to some inconsistency in the specifications of the stone walls generated.

Some are thick, some are thinner, some are dark, and some are light, but it does not hinder the high efficiency of building stone walls, which is faster than the work efficiency of tens of thousands of excavators.

After all, the excavator still has to dig, move the rocks, and then pile them up, while the rock elves only need to pile up the stones according to the area demarcated by humans.

The specifications of the stone wall are not up to standard, and a few more stones are piled up.

Soon, a two-meter-high stone wall was formed on all sides of the first hill, firmly enclosing the mountain in the center.

Below, in mid-air, including Yu Yang's tropical dragon, there were human helicopters, and many trainers were riding large flying elves, observing the progress of the project.

This process does not take more than an hour.

"Zheng Gong, take a look, is the stone wall of this specification below enough to prevent the flames from spreading out?"

Professional matters have to be handled by professionals, and Yu Yang doesn't know if the stone wall built by the rock elves can prevent the spread of mountain fires.

"You can't see it, practice makes you know, just send a few fire-based elves to simulate it."

Zheng Gong, who was sitting on the helicopter and holding a telescope to observe the situation below, smiled, pointed to a stone wall in the north area, and said,

"After my visual inspection, the stone wall in that area is the thinnest, let's go there and test it first."

"Okay." Yu Yang nodded, took out the liaison, contacted people from all sides, and prepared for the test.

…

In front of the stone wall on the north side of the hill, two cutty dogs, along with a dozen humans, stood aside.

Yu Yang touched the heads of the two Kati dogs, stuffed them with two tree fruits, and said with a smile:

"Two little ones, you go to the left and the right respectively, and release the flame vortex"

Originally, he wanted Cutty Dog to release the jet flame, but considering that the power of the jet flame move was too great, the momentum of the mountain fire would not have the strength of the jet flame at all, but the flame vortex was more like it.

The range of the flame tumble is large, but the power is limited.

"Wow!"

The two catty dogs responded obediently, and immediately separated a few steps, and between the fiery red hairs, a trace of heat escaped, and soon formed a tumbling vortex of flames, which quickly swept towards the stone walls in the left and right directions.

The height of these two flame vortex is about three meters high, and there are no trees more than 5 meters high in the hill behind them.

Both Android and Apple are available. 】

Huhuhu~huhuhu~

The blazing flames scorched the stone walls, baking the sturdy-looking rock walls like softened candy, and little by little they flowed like chocolate.

It looked delicious, but the hot mud that flowed from the surface of the stone wall fell onto the floor, making a stabbing sound, and it was getting smaller and smaller.

Until the effect of the flame vortex disappeared, the stone wall, which was originally 2 meters high, shrank to about 1.5 meters.

"In fact, the effect of the stone wall is not bad, the rock has a restraining effect on the flames, the strength of these two catty dogs is much higher than the strength of the elves who built the stone wall, and the power of the mountain fire is definitely not up to this kind of destructive power."

Yu Yang explained to others who didn't understand the elf moves.

Zheng Gong thought for a while and said, "Just in case, build the stone wall up 0.5 meters high, and the walls in other places look thicker, but you also have to test it, and you can't be deceived by appearances." ”

"Okay, Zheng Gong, do what you want."

Yu Yang agreed, and the staff on the side immediately went to inform the people and elves in other places.

Half an hour later.

The height of all the stone walls was stacked up to 0.5 meters again, and in each direction, there were roughly Cutty Dogs releasing flame vortices to test the strength of the walls.

Since the stone wall was being piled up too quickly, it was still early for Yu Yang to expect, so let the on-site staff take a break and move on to the second plan of the day - arson*.

It is about to enter winter, the air is already very dry, and the more than 100 fire-based spirits sent out only slightly released fire-based moves, and the vegetation on the mountain is really dry firewood encountering the flames, and they begin to burn in a roar.

Thick smoke rose and shrouded the nearby sky in a haze.

The burning of vegetation in the mountains is not as fast as the rock-filled walls.

In order to make the vegetation burn more thoroughly, it is necessary for the fire elves to continue to add fire, and some plants with high humidity have to be burned repeatedly, and after more than an hour, the green plants on the mountain have burned a large area, and the Yu Yang who is standing in the distance has also smoked into a big flower face.

"Ahem, ahem, oh mom, this smoke is too choking."

Only now did Yu Yang understand how difficult it was for the firefighters who poured out the mountain fires, and even he felt very uncomfortable when he was smoked by the smoke while standing in the distance, let alone those who went deep into the mountains and forests to extinguish the fires.

……

After five days, the fires on the twelve hills in the northern part of the reserve were finally extinguished without any incendiary material, leaving only a charred black place.

On the human side, hundreds of water spirits were asked to use the rain trick to extinguish the remnants of the twelve mountains, and when the high temperature in the mountains completely dropped, there were more than 60,000 rock and fire spirits, as well as thousands of humans who were responsible for engineering transformation, driving large and small engineering vehicles into the barren mountains.

The elves alone can't completely transform the mountains and forests, and they have to help humans scatter sand and gravel and tamp the land.

Regarding this aspect, Yu Yang has nothing to command more, it all depends on professional people, and he is basically semi-detached.

At the same time, in the past six days, new news has also come from the wind speed dog boss, the axe mantis boss, and the moon Yin Bu, who are far away in Qiong Province to help rescue them.

The second batch, with a total of about 120w washing elves, is on the way to migrate again.

Due to the special geographical reasons of those secret realms, among the 120w elves of various attributes, among them, fire and rock elves account for about one-twentieth.

The plan could not keep up with the changes, and the scope of the transformation of the northern stone mountain had to be expanded again.

According to this trend, the reserve must provide suitable habitats for more than 60w fire and rock spirits.

However, with the experience of the first successful migration, Yu Yang does not have to do everything himself as he did at the beginning, and all the heavy work is done by the staff who continue to join the elf-related industries.

……

Time passes, years pass, and time enters the first month of the coming year.

"After nearly three months, this is the last group of elves to migrate."

In Qingshan Village, which is full of activity model houses, Yu Yang sighed while holding a rice basin and shaving rice, while looking at the big trucks full of fruit trees passing by the entrance of the village.

"Yes, the last batch, 50w elves, is expected to complete all the relocation work within five days, so far, the four secret realms, a total of 623w elves, will all be moved into the Xicui Elf Conservation Area."

Yu Chun also held a stainless steel rice bowl and answered Yu Yang's words first, and then he ate in a big gulp, obviously hungry.

"Hard work, Yu Chun, this migration is over, you should be promoted, right?"

As a half-official "idler", Yu Yang did not hesitate to ask.

"My superiors asked me to take charge of the promotion of elves in the future, so it can be regarded as a promotion."

Yu Chun did not shy away from it, and replied with a smile.

"Oh? Elf promotion, is the above going to start popularizing elves nationwide? ”

It stands to reason that Yu Yang's news will be better than Yu Chun's, but he has not heard anything outside the window recently, and only hides near the protected area to play with the elves at home, and he is indeed a little dull to the news outside.

He didn't even attend the meetings convened by the leaders a few times.

"Let's come to the next year, in the spring after the year, I guess I will invite you to a meeting in the capital to discuss the specific matters of promotion."

Yu Chun wiped his mouth,

"There is a grapevine, it is said that the United States, Britain and other powerful countries have begun to encourage citizens to raise elves, and their military has begun to incorporate some powerful elves into the army, train with the army, and treat them as regular armed forces."

"And what's going on? No wonder the top is in such a hurry. ”

Hearing Yu Chun's words, Yu Yang was secretly surprised in his heart.

I didn't expect that so many things had happened internationally in the past month or so much that he had been lazy.

Also, the elven invasion is not only invading the Xia Kingdom, but generating spatial rifts all over the world.

The people of other countries were influenced by the elves a lot more than the people of the Xia Kingdom.

Each country has its own protection system.

Some are radical, some are conservative.

Obviously, a certain country, which has always been arbitrary in the world, has fully noticed the importance of elves and began to vigorously develop elf-related industries.

Yu Yang understands that this is a brand-new track, and which country has a strong comprehensive strength of the elves, it is very likely that the entire country will be more confident in international exchanges.

You know, the elves who stand at the top are more deterrent than nuclear weapons.

An invisible "elf race" has begun.

Ah no, I'm afraid that as early as the beginning of the elven invasion, the great powers began to compete with each other.

"Captain Yu, I have something to tell you, a few days ago, a friend of mine who works abroad sent me a message, saying that on the website of the United States, someone is already discussing some of your things, I guess that the intelligence agencies of some countries have already included you in the object of observation, and you should be very careful in your usual behavior."

Yu Chun put down his job and said in a somewhat worried tone.

Yu Yang smiled, pretending to be relaxed on the surface:

"Oh? I didn't expect to be on the watch list, but I was a little flattered. ”

But in fact, he was still quite nervous inside.

In society, he is just an elf science master who has in-depth cooperation with the official.

For example, some information about space cracks, elf cultivation, and knowledge of divine beasts is all circulated internally, and it is unknown how much foreign intelligence agencies have inquired about.

"But you don't have to worry too much, I estimate that our country's security department has been secretly protecting it for a long time, not to mention that there are so many powerful elves around you, I only recommend that you don't go abroad during this time."

"Well, I'll be careful."

Yu Yang nodded, and was about to continue......

Suddenly, he heard a clatter of meat pads stomping on the ground not far away.

He was already a little nervous, and subconsciously looked at the voice coming from the voice.

I saw the dark moon Yin Bu, who appeared a meter away from him at some point.

With the strength of Moon Yin Bu, the stomping sound of the meat pad was naturally not emitted by it.

But...... Two small Yin Bu squatting beside it.

Forehead...... Although more than a month has passed, the original little Yin Bu is actually not small now.

"Booy!"

The two Yin Bu shook their noses and smelled a familiar smell belonging to Yu Yang.

It's the taste of the grill!

They screamed happily, and without saying a word, the two Bubu pounced and threw themselves into Yu Yang's arms at once.

"Buibui~"

"Let's da, da~"

The two Yin Bu were tired of Yu Yang's arms, constantly arching his chest with their little furry heads, and after some intimacy, they pulled them to his left and right shoulders with their front paws, stuck out their tongues, and licked his cheeks.

"Oops, two clingy little guys, haven't we seen each other for a few days?"

Yu Yang picked up a Yin cloth in one hand, stretched out his nose and rubbed it against their cheeks.

A few days ago, most of the Yin Bu of the Yin Bu Forest also moved to the Xicui Elf Nature Reserve, of course, there are some Yin Bu "elders" with good strength and various attributes, who are still working on the migration of elves.

The two little Yin Bu didn't have the ability to help the other elves, so they obediently stayed in the new habitat to live.

Yu Yang also meets them often, who would refuse a large group of lovely Yin Bu.

Holding the two Yin Bu into his arms as hand warmers, Yu Yang stood up, walked to the moon Yin Bu with a smile, and asked:

"What's the matter?"

"Cloth~"

Moon Yin Bu shook his head, stretched out his paw and pointed at the elves who were lining up at the entrance of the village.

"Oh...... You mean, your mission is complete, and you won't help migrate the elves anymore? ”

Yu Yang read what it was trying to say.

"Cloth!"

Moon Yin Bu nodded.

"Okay, hard work, this is also the last group of elves, from now on, you can stay in your new home and live carefree."

As he spoke, Yu Yang rubbed the chins of the two little Yin Bus.

"Cloth ......"

Who knows, after Moon Yin Bu heard his words, he sighed humanely, as if he wanted to say something, but closed his mouth again.

"What's the problem? If you have a question, tell me directly, do we need to hide anything from each other? ”

Yu Yang saw its entanglement and asked directly.

"Cloth ~ Cloth ~"

The dark purple light flashed, and a dark stone appeared on the claws of the moon Yin Bu.
