Yaoyuan Shou set aside the worn and deformed digging drill bit and waited for his body to cool down.

Four underground mines were opened.

So far, a total of 4 electrooscillators have been excavated, and 3 of them have been handed over.

Yaoyuan knew that in order to gain the trust and support of the Yao civilization, he had to show value. The results of underground excavation are to prove their strength in exploration and excavation.

As the excavation deepened, it found that the situation was not optimistic.

Digging deep underground is difficult because of the massive vibrations that can occur at any time in the Silver Plains. According to the Yao Nationality Research Station, it was a shock caused by the fall of the electric vibration star.

This is difficult to determine in size and intensity. It could be a single star falling, hundreds of stars falling, or even rain that causes prolonged oscillations and ground waves.

When the vibrations reach the ground, they will collapse the mine.

In order to maintain the passage and the mine shaft and reduce the risk of collapse, it is necessary to do a good job of supporting the construction in the mine. However, this not only requires the consumption of a large amount of external materials, but also requires more time to be spent on the construction of the well, which does not produce results quickly.

Yaogaki doesn't have that energy right now.

It must obtain enough electric vibrating star fossils in a short period of time in exchange for a steady stream of aid from the Yao civilization. The amount of support and resources it can get is directly related to how quickly it mines stars.

It's obvious.

Yaoyuan knew that he must seize this once-in-a-lifetime opportunity.

Originally, it was mentally prepared to sleep beneath this world for a long time until all its energy was exhausted.

It has done everything it can to call for help, even releasing and receiving signals on a large area of the ground.

Except for some signals from the electric oscillator, there was no response.

Yaoyuan was the first to admit planting.

Luca's appearance has made a disheartened and hopeful one.

"Then let's develop this place together."

The skeletal-shaped metal creature said.

Yao Yuanshou was a little moved at the time.

Although only for a moment.

After making contact, Yao Yuan Shou discovers that Luka is not stupid, he is a veteran of many battles and has a very clear judgment of danger.

The other party showed an unwavering optimism.

It believes that the Yao civilization behind it can give enough support to the front, and there is no doubt that the Yao civilization will gain a firm foothold in this strange and dangerous world, and carry out further exploration.

"As a soldier and a fighter, you must learn to trust your comrades and partners unconditionally," Luca said. When facing danger, you need to trust that the other person can pull you along, and you also need to protect the other person's back. ”

"You can't live without that."

Yaoyuan was very envious.

Envy the Yao civilization behind Lucca, envy its protection from the gods, envy its experience and sharpness.

It doesn't remember when it had someone it could trust. It was probably my own vague and conscious childhood, when I knew less, and I was not so painful and tired, and there was a kind of simple stupidity.

Did Lukka find out he was lying?

Yaogaki is not sure.

Ninety-nine percent of what it says is true, and the only thing that is different is about the life called Yaogaki Shou.

Now Yaogaki is very uneasy.

Because Luca has been out of the mine for 4 whole days.

"I received an order to go back, and I'll be back as soon as possible."

After saying so, it never saw Lukka again.

On the third day, Yaoyuan flew all the way to the research station and asked about Luca's situation.

The sword-bearer said, "I'm sorry, but I have no comment. ”

The cold tone made it faintly feel that it was not good.

On the sixth day, the head of the cave went there again, and this time he didn't even see the Blood Knight.

Only a skeleton man in a heavy hazmat suit received it and told it, "If Mr. Luca returns, I will tell him for you." ”

Polite and watertight.

Correspondingly, the research station of the Yao civilization is visibly expanding in scale with the naked eye. The crystal walls continued to extend outward, and a large amount of sand and soil transported from the outside world transformed large fields, and the Yao people forcibly built a farm town on the Silver Plain.

They also optimized their cultivation methods, first cultivating the roses to be as tall as trees in the Yao civilization and then transplanting them.

Although the survival rate of adult transplanting is very low, a large number of hard piles are used to create a black and white forest of roses.

Yaoyuan Shou also saw that the laborers of the Yao tribe were already digging the mine.

They are very large-scale and standardized, and the workers work in different stages in an orderly manner, using special pickaxes and shovels, to chisel the blocks of not very hardness, concentrate them, and then send them back to the other side of the world.

Even if the Yao people's power is curbed and it is difficult for everyone to move here, they can still use huge manpower to complete all these infrastructures.

Luca has not been heard from again, and the station continues to expand.

From these changes, Yaoyuan drew a sign of unease.

- The Yao civilization may not need itself.

It was only a matter of time before they dug up the electric oscillators.

On the tenth day of Luca's departure, Yaogaki was completely unable to sit still.

It decided to go and ask to join the station and see what was being said.

If it is rejected, it means that the Yao civilization really wants to abandon itself, a worthless outsider. If you agree, there may be a little hope.

It exited the safe hole and saw a broad figure in the distance.

It was Luca, who was wearing a heavy feathered protective suit.

At this time, Lukka stepped on a board with four wheels under it. It is able to move smoothly with one foot fixed to the board and the other foot on the metal floor.

Very basic sporty structure, but practical.

Lukka circled around Yaoyuan's head and stopped with one foot elegantly: "This is the most practical 'glide board' made by the engineers in the rear, stepping on this, it can be several times faster in the Silver Plain, which is very labor-saving." We have also tested before that when encountering ground waves caused by vibrations, even if the center of gravity is lowered, it can glide smoothly through undulations. ”

"I taught the people at the station how to use this to skate on the waves. Now this thing has become everyone's standard, and you have to attach one to your backpack when you go out. ”

Yaoyuan Shou breathed a sigh of relief in his heart: "Are you going to teach pulleys these days?" ”

"No, Lord Blood Knight forced me to take three days off. Later, I was testing this tool with them, and it was not easy to calculate and test the most suitable material and size......

The silver skull picked up the glide board on the ground, looking very precious.

Yaoyuan was speechless.

What.

That's what you're doing?

"There was also a classified mission, which at that time had to be kept secret centrally, can't say. Now that I've been authorized and lifted by Lord Blood Knight, I can finally tell you. ”

"Let's go, I'll take you to see a good thing."

Yaogaki followed Lukka all the way back to the research station.

Lukka pedals his beloved skateboard around the bend and enters a courtyard surrounded by crystal walls and a black and white forest.

There are Yao guards standing guard, and they hold shields and spears in their hands, all of which are made of that cyan metal, and have the same strength and density as the pickaxe.

To Yaoyuan's surprise, there was a strange life shaped like a snake inside.

Its body is made up of silver balls.

Yaoyuan repeatedly confirmed.

That thing is made up of 11 electric stars!

The Electro Star Aggregate was now coiled on the ground, burying the head at one end, which for a moment thought it was, into a large crystal bottle that looked like a jar, and absorbing the contents.

Purple flocculent gas wafted in the crystal bottle.

It is gaseous energy of high purity.

Although it is not as stable as the World Stone and the All-round Stone, it is very easy to absorb and adsorb, and the gaseous state is a relatively easy form to use.

Yaogaki turned his attention back to the electric oscillator aggregate.

"What's that?"

"We call it the Star Worm." Luca looked at the eating life in front of him: "That's what I've been busy with these days. ”

"This guy has infiltrated our research station underground and stole the bottles we have stored. It was the Crystal Bottle, which contained magical energy, and it crept in, emptied the twelve, and then we caught it. ”

The silver skeleton crossed his hands on his hips and said proudly, "This guy was still trying to run, but he was hit by the Blood Knight, so he used our special weapon to deal with the electric star, the water gun. ”

"When the water stored in the glass tube is pushed, squeezed and sprayed, they are drenched in water, and a large amount of white smoke comes out of the mutilated and broken places on the body, and it ignites at once."

"This is a devastating blow to the electroswords, not only do they lose a lot of energy, but they will also be further severely damaged in their bodies. It couldn't move all at once. ”

"We have come up with this weapon through repeated tests by two electric oscillators, "Alpha" and "A-Star". Although they are not suitable for outside tasks, they are not bad as subjects to be studied, they have strong personalities, and are even willing to take the initiative to be tested in exchange for magical energy supply and continued repair. ”

"Under normal circumstances, the electric vibrator is actually not afraid of water, but it can't land on the ground."

"Through water and magic bottles, we tamed this star worm - it is said to be a star worm, but it is actually a special symbiote composed of 12 electric vibration stars."

Lukka pointed to the star worm in front of him and explained to Yaogaki Shou, "They were connected to each other, and at first two falling electric stars were attached to each other to form the first binary star, and then they continued to look for other electric stars. It's best to take advantage of the heat when you just fall, and there is still power to supply and store......"

"During the screening process, end-to-end consent is also required, because the new electrosphobrating star can only be connected on both sides of the star worm. If both docking members disagree or are unwilling, then they cannot be connected. ”

"We took it to the Temple of the Sun and asked. There are also compatible and incompatible stars themselves, and like you said the channel, they are judged by the frequency of the flickering jump. Only by being close can we fit and resonate and act together, otherwise we will become unsynchronized. ”

The Silver Skull concluded, "I've been working with the Star Worm for a while, gradually making it understand that we're going to dig up the Underground Vibration Star, and we'll provide it with a magic bottle as a reward. The deep underground will gradually be handed over to it, as it is better at finding other electrosillators. What we have to do is to do a good job of support and supply, to give it a reliable and stable rear. ”

"There is more than one star insect in the Silver Plains, it says that it has seen several, but everyone has different channels and does not interfere with each other."

"In other words, our work is about to be handed over to them. As long as we keep looking for Star Worms and domestication, they will be able to cooperate with each other to complete the continuous mining of underground electric vibrations! ”

Luka Quack laughed: "Is this good news?" ”

"That's nice."

Yaoyuan said with his mouth open, but he was extremely shocked in his heart.

The progress of the Yao civilization is too fast.

How should I deal with myself?

"We have new jobs." Lukka looked at it, as if he had insight into what it was thinking: "Our job is to pay attention to the condition of the star worm, the second star worm has been found and is also in the process of domestication, and then the star worm will be handed over to us." ”

"In terms of signal communication and surveying, that's where you're great, right?"

Yaoyuan was stunned for a moment, and then hurriedly said, "Of course, I am a professional in this area. ”

The two of them were silent all the way back to the safety of the cave.

Yao Yuan Shou finally made up his mind: "Actually, the traveler is just a disguised identity, and my real profession is a "standard pawn", specializing in entering various spatial passages, tunnels, and crevices to do things...... In the words of your Yao people, I am a burglar. ”
