The center of the earth has collapsed, gravity is chaotic in many parts of the planet, and the underground environment is even more complicated.

However, with the ability of the Shadow Dragon Star Armor, even if it dances on the surface of the star, it is not a difficult task, and it is even easier to enter the severely damaged center of the earth.

Once a mecha master drilled deep into the center of the earth and ventured to find the Bo Dun Pole Stone. However, they didn't have the Zihuang Demon Wheel and the magnetic power of the Bo Dun Polar Stone to guide them, and it was really difficult to search this huge earth realm. As for letting the mechs dig up, it's better to save it! The collapsing geocentric environment is extremely harsh, and it is very likely that the sergeant-level mecha will not return if they go deep, let alone the small mecha soldiers.

In this way, Li Yuan was fulfilled.

Speaking of which, this is the place where he made his career, although the geographical environment has changed, but there is always a feeling in it. Thinking back to what happened on the desert planet, getting acquainted with Sasha, joining the Sky Wolf Squad, and participating in a five-silver star mission, just like yesterday.

Who would have thought that the world is unpredictable, whether it is the Andersette family or the Sha family, neither of them has mined much Bo Dun Apole Stone. Zuihou went around in a big circle, and Li Yuan returned to the starting point, he wanted to take a new step and make the mecha strength take off.

In front of him, the debut path of magnetic light bloomed, and the magnetic force was sealed within several kilometers, supporting a small world. The center gathers a vigorous dark blue, and as the center of the earth crushes over it, the magnetic light beats like a heart.

"Awesome! Under the action of the geocentric force field, the Bodun Polar Stone gathered together to resist the pressure. Hehe, it's really hard to find a place to break through the iron shoes, and it takes no effort to get it. Of course, it was someone else who stepped on the iron shoes, and we didn't have to work on it. Li Yuan's face smiled like a flower, and when he looked at the magnetic light in front of him, he couldn't help but be a little obsessed.

This magneto-light is the essence of the universe, and this dark blue is a miraculous precipitation.

Today, when he came into contact with Bodun Aurus again, Li Yuan was still a mecha soldier, but he had become a powerful dragon soldier from a first-class rookie, and the mecha was still the same mecha, but the essence had undergone earth-shaking changes.

"The longest diameter is 383 meters, and all the Bo Dun Polar Stones are adsorbed together, and due to the continuous strengthening of the pressure at the center of the earth, it is equivalent to making it carry out a preliminary refinement. When they first came together, they must have been much larger than they are now. Elizabeth listed the relevant data on the light screen, no wonder the magneto-optical is so vigorous, dare to love that most of the Bo Dun Polar Stones in the star body are gathered, with a diameter of more than three hundred meters, and the mecha is less than six meters high.

"Okay, it saves us a lot of trouble." Li Yuan carefully inspected the vicinity and couldn't help but wonder: "The magnetic light here seems to be strong, but in fact, the fluctuations are very subtle, and a field has been formed, if there is no magnetic guidance of the same kind, it is really difficult to find this place." Who would have thought that there were so many Bo Shield Ausus Stones hidden inside this planet, and if those mechists knew about it, they wouldn't have killed me? It's just that how do we take the Boeden Apole Stone away?"

"Master, there is a way, but it will cost a little more." Elizabeth said with some embarrassment.

"Oh? Let's hear it. Li Yuan touched his chin.

"That is, when the remnant treasure was broken, all the heat energy stored in the Black Cube was vented, and the terrifying heat and destruction liliang were used to bombard the Bodun Akuroshi to reach the standard of high-end smelting. However, the reason why Bodun Apole Stone is precious is because of its super defensive ability. Therefore, I am afraid that there will be eight limit treasures in the future, and all the treasures related to heat and decomposition rays may have to be exploded. In this way, the impurities can be eliminated and we can get the part we want. "What Elizabeth said is the truth, the Bo Dun Polar Stone has gathered and formed a powerful whole, and it takes a lot of thought to refine and divide it.

"What a luxury plan." Li Yuan sighed slightly and said, "However, with the conditions we have at hand, it seems that only this method can work." In this way, leave the fire phosphorus god stone, and if there is flame energy and heat energy left after the bombardment, use it to absorb it. If you still can't change the Bo Dun Polar Stone, you can only blast this top treasure out and try it. ”

"Master, please rest assured, with so much investment, you will definitely be able to blow up the Bo Shield Austic Stone. I have calculated, although I have never seen so many Bo Dun Apole stones gathered together, and the budget results will inevitably vary, but the general direction will not be wrong. The Fire Phosphorus Divine Stone has a strong heritage, and it can take the opportunity to evolve into a secret treasure, and it has this qualification. Elizabeth was confident in her computing skills.

"Let's get started, then!" Li Yuan condensed slightly and began to communicate with the Black Rubik's Cube.

Through the observation of the past few days, as well as the continuous shattering of the remnant treasure, Li Yuan has figured out some ways to control the black Rubik's Cube, the first is the fit, using the peak fit of the scholar-level level, constantly generating ideas to urge, reaching a certain critical state, you can use the mysterious black Rubik's Cube. You can't do something too hard, but it's easy to do it by releasing stored energy.

"Boom!"

On the top of the mecha's head, a faint black phantom appeared, and soon the phantom became condensed, like a large black seal.

The bright flame of light surged outward, and between the projection of the black cube and the black cube, there was a very unique spatial channel, and it was extremely convenient to vent the heat, as long as Li Yuan moved his thoughts.

Soon, the light flames converged into a wave and shot towards the Bodun Pole Stone.

The heat frenzy came wave after wave, even if this liliang came from the remnant treasure, but after all, it was a high-end energy product in the universe, and Li Yuan smashed so much, how huge the heat gathered was, even he had no idea.

"Boom, boom, boom......"

The sound traveled far away, and in addition to those flames, there were also bursts of disintegrating rays.

Li Yuan's investment is definitely not small, anyway, his Eight Limit Treasures have nothing to do with thermal and fire energy, as well as destructive liliang such as decomposition rays. Therefore, it is not a pity to use up the stored energy.

The bombardment lasted for more than two hours, and when the Black Cube slowly stopped rotating and no longer released light flames, the hill composed of Bo Dun Polar Stone did not disintegrate, but became more refined.

It was slowly tempered from a height of 383 meters to a height of 36 meters, removing a large number of impurities, and the magnetic energy became more and more restrained. If there is only this kind of height, it is not difficult to teleport to the mecha core cabin for storage, and it will take some effort to separate the nodes in the open space at most.

Only, there are still problems.

The synthesis tank can't swallow such a huge block, and if Li Yuan wants to quench the magnetic power of the Bo Dun Apole Stone through the Black Rubik's Cube, he needs the slightly smaller Bo Dun Apole Stone. Therefore, 36 meters is not up to par.

"Then, there is only eight limit treasures to be blown up, in order to smash this big guy, it is really extravagant!" Li Yuan sighed, fortunately, on the surface of Bodun Apole Stone, there is always a layer of heat lingering.

In this way, the Fire Phosphorus Divine Stone has the hope of using this residual heat to be promoted to the top secret treasure, it is originally a fragment of the collapse of the secret treasure, although it cannot be compared with the Zihuang Demon Wheel, but the foundation is also strong, as long as it encounters an opportunity, it can be quickly improved.

Li Yuan was quite looking forward to it, the Fire Phosphorus Divine Stone was a powerful hole card he prepared for Kui Ye, through the scene he saw in this competitive competition, he found that the strength of the legion was very important, even if there was Sha Buregret to help, it was still difficult to improve the strength of the legion.

Right now, it is an opportunity to engage in more than 200 pieces of eight limited treasures. Of course, he didn't need so much, at most he left a few treasures to exchange money in Daxia in the future, and the other treasures had to be distributed to enhance the strength of the people around him.

In fact, being able to find such a large piece of Bo Dun Apole Stone is much more precious than the Eight Limit Secret Treasures in Li Yuan's opinion. And it can be used to help the Fire Phosphorus Divine Stone regain its entry into the secret treasure class, and it is also a luxury.

The synthesis tank was put into operation, and the black and white force field twisted, crushing the eight limit treasures, causing them to gradually shatter.

Bombarding the Bo Dun Polar Stone is not to directly throw out the eight limit treasures, but to extract energy first, and then erupt through the projection of the Black Rubik's Cube.

The flames of light converge into a wave, supporting the Bodun Pole Stone. The tempering was much longer, lasting about five hours. Li Yuan had been observing the changes in the surrounding magnetic energy, and when the volume of the Bo Dun Apole Stone had shrunk to twenty-eight meters, the Demon God Arm attacked violently.

"Boom Rumble......

The blast wave radiated, tearing the rocks several kilometers apart, expanding a large space in the center of the earth, and the lava in the center of the earth flowed in, forming several upside-down lava waterfalls.

The heat around him was rising, and the Bo Dun Aura-Pole Stone was attacked by the Demon God Arm, and it was only shaken a few times, and the surface did not change much.

Li Yuan breathed a sigh of relief and said with a smile: "It's finally successful, let me wait!" This Bo Dun Pole Stone is the product of the accumulation of many Bo Dun Pole Stones, and the more it is refined, the more refined it is. However, those impurities that are difficult to remove are also gradually gathered together through magnetic fluctuations. The heat just now was just right, and when the impurities were about to go, he used the dragon power to disperse its internal shock, and the surface looked intact, as long as it was refined for a while, it could be dispersed by itself. If you hesitate for a moment, I'm afraid you're going to swallow this big guy whole. Hehe, fortunately, fortunately!"

There was not much time, and with a muffled sound, the "hill" that had been condensed a lot collapsed and turned into more than 200 pieces of the purest Bo Aegis Pole Stone of various sizes. This can no longer be counted as a stone, but a high-grade rare metal, but it still needs to be crushed by the black and white force field of the synthesis tank, and sent to the repair spirit groove to be forged into a mecha skeleton before it can be replaced.

The projection of the black Rubik's Cube rotated and absorbed, absorbing all the heat that lingered on the Bodun Pole Stone. The shadow dragon cloak shook, and the Bo Dun Apole Stone was included in the core cabin by Li Yuan.

The current core module has been basically integrated with the space node, but there is still a lot of follow-up work to be done, especially the transformation of the synthesis tank and the repair spirit groove, which is very complicated and cannot be completed perfectly by the soldier level.

The mecha began to float, and Li Yuan was full of confidence.

Through the harvest of these seven or eight days, he found that the Shadow Dragon Star Armor was very suitable for exploration, and there were many dangerous places that no one dared to go to in the Sha family, which was simply an undefended treasure trove for him.

Of course, the Zihuang Demon Wheel and the Black Rubik's Cube also contributed to it, and Li Yuan had a jihua in his heart, and he wanted to ask Sha Bu for advice and dig out all the resources that could be used in the vast territory of the Sha family.
