That's because if the energy is strong, it can generate a magnetic field, which can isolate other things, but it can't be explored, which is a flaw in itself, Mu Yin took advantage of this and began to point out where they were digging, and also instructed Zhang Yi how to use mental power to explore, of course, these are not broadcast live.

Probably digging down for more than twenty meters, the soil is getting harder and harder, and there are basically rock layers behind it, and then the soil system is obviously useless, Mu Yin knocked on those rock layers with his hand.

"If I'm not mistaken, these rocks are the rough stones that wrap the power stones." Mu Yin said.

"How is this going to be mined?" Chen Peng took out the armory shovel and tried to dig it, but there was not even a trace left on it.

Mu Yin took out the magic sword and injected spiritual power to slash it hard, and soon there was a deep sword mark on the rock layer, and then she directly used the magic sword to dig down a stone on it, revealing the things inside, which was a different color from other rocks, it looked like jade, and the color was earthy yellow.

"This should be the power stone." Mu Yin dug down one of the stones and felt the energy inside, it was not spiritual power, but it was indeed energy.

"This is the Earth System Star Source Stone, and it is said that it can only be found on newly born planets and newly evolved planets." Bai Xue opened her mouth to Muyin to popularize science.

"What's different about this ore?" Mu Yin heard something unusual, so she asked.

"Star source stone is a very peculiar ore, if it runs out of energy, as long as it is placed in the universe, it can be charged and reused after a period of time, it is a very unique reusable energy source, and even when the universe is sailing, it will specially use this energy, which can be replenished while flying.

Therefore, the Star Source Stone is very popular in the interstellar world, and many Star Thieves and Explorers travel around the universe in order to find the evolving planet and seize the Star Source Stone, because the newly born planet is very unstable, so they usually choose the evolving planet to start. ”

"So, the purpose of those aliens is this ore?" Mu Yin's expression did not change, unlike everyone else who had an ugly face, she had long known that there would be aliens coming, since they would come, there must be something they coveted, and now she knows.

"Yes." Bai Xue nodded.

"How did they find those evolutionary planets?" Mu Yin is more concerned about this, it is obvious that the stars are far away from the solar system and even the Milky Way, otherwise it would be impossible not to develop them here.

So, how did they find here? Soon Bai Xue gave her an answer: "When the planet evolves, there will be a wave of energy that escapes, this wavelength is very peculiar, it is generally not easy to capture, but it will not be easily dissipated, it can travel far, far away, almost half of the universe, and now the interstellar has mastered the ability to capture this energy wave and calculate the approximate azimuth distance." ”

"It's not obvious to tell the whole universe that I've evolved, come and take it." Mu Yin was a little speechless, she didn't expect it to be like this.

"How soon will they come back?" After listening to the whole process, Chen Peng asked a little worriedly.

"I don't know, if it's close, it will only take a few years, and if it's far, it may take more than ten years." Bai Xue shook her head, she didn't know the interstellar coordinates where the blue star was, so she couldn't judge. "But even if it is closer, it will be three years before they enter this planet."

"Why?" Others are a little puzzled, why do they say they have to wait three years?

"When the planet evolves, the energy escapes, and an energy shield will be formed above the outer atmosphere of the planet, protecting the entire planet in it, so that the energy will not escape into the universe, and it will dissipate after three years, and in three years, the outside cannot come in, and the inside cannot go out." Bai Xue talked about the evolution of the planet.

"Why didn't you mention this before?" Mu Yin didn't expect such a situation, it seems that they still have three years to go, which is not enough but enough for them to grow.

"You didn't ask." Bai Xue was very innocent, looking at Mu Yin innocently with a pair of Danfeng eyes, and the latter wanted to fight birds.

"Ahem, it's okay to know now, by the way, are all the energy mines on our planet like this?" Seeing Mu Yin's intentions, Chen Peng hurriedly changed the topic.

"No, generally speaking, even if it is planetary evolution, there will not be many star source stone mines, at most two or three." Bai Xue shook her head, but Mu Yin felt that it was not necessarily, because, Blue Star is the center of the universe, and the planet where the origin core is located, can it be the same as other planets? Definitely not.

"This can only be replenished in cosmic space?" Mu Yin also asked her about her curiosity.

"Yes, it is not possible to replenish energy on the planet." Bai Xue nodded again.

"Okay, by the way, is there any mining machinery?" Mu Yin nodded, and then thought of another question, the rough stones outside can only be split with a magic sword, so how to mine?

"There's a laser cutter that can easily cut through this kind of protective rough on the outside, but there is no material to make that laser knife at the moment." Bai Xue replied, and then regretfully announced the difficulty.

"To say it is to say it in vain." Mu Yin is not angry, it seems that in a short period of time, she can only come to mine, why is she so unlucky.

Now that she has found the energy mine, she naturally has to dig some back, so Mu Yin began to use her sword moves here, and when she went down with a sword, she chiseled a big hole in the extremely hard rock wall, and the stones that were dug down were all put away by her and the spatial ability.

Until her aura was exhausted, it was only digging close to a depth of ten meters, after all, it was not the tenacity of magic weapons that was used to dig this, but the sword qi, it seems that this stone should be immune to physical attacks, but not to spell attacks.

What's weird is that it's also immune to the pure energy attacks of spell attacks, but not to physical attacks caused by spell attacks, so to speak, attacks like fireballs, water balls, thunderballs, etc., are ineffective, but if you condense a fire knife and water knife, it can cut it, but it is not as effective as her sword energy.

After experimenting with the water ability, Mu Yin determined how to dig this thing, and Mu Yin began to instruct others to draw energy out of the body and condense it into weapons, a skill that is not so easy to master.

What are spells, magic, skills? It is the way to give energy forms, such as fireballs, fire dragons, water balls, water knives, these are all given energy forms to achieve the effect of external attacks, and it is very difficult to directly guide the energy out and then condense into the desired form, first of all, the energy will dissipate after it is channeled, and what they have to do is to shape them before it dissipates.
