Lu Yi sat cross-legged on the ground, staring intently at the black thunderball that had been compressed from the original three-foot radius to the current black thunderball the size of a watermelon, to be exact, at this time, the thunderball was no longer black, but had become a light gray, Lu Yi could vaguely see that inside the gray thunderball was countless dense small thunderbolts that kept bombarding the golden dagger. The dagger was no longer as golden as it was before, but had become no more brilliant, as if the thunder and lightning had caused it a lot of damage and made it lose its aura, but it made Lu Yi feel that it seemed to be glorious and restrained, more condensed and clumsy than before.

Half a day later, the thunderball was finally consumed, and a dull dagger lay quietly on the ground, this dagger was no longer the original golden color, but turned into a dull yellow similar to yellow sand, the centipede shape was still in the middle of the dagger, but the color also changed from the original black to almost the same color as the dagger, this color is very close to the color of the centipede body caught by Lu Yi. Without the phenomenon of the crystal boots being infused with the aura of heaven and earth last time, and there was no vision of the appearance of the machine spirit, the dagger was like a dead thing, there was no aura at all, Lu Yi frowned, could it be? This dagger failed to advance? Lu Yi stretched out his hand and took a shot, the dagger jumped into his palm, Lu Yi found a seventh-order armor and tried it, and found that its sharpness had been greatly improved, and the seventh-order armor was easily separated, so that this thing didn't seem to have failed, why didn't there be that follow-up step? Lu Yi was puzzled, but he didn't dare to casually go to the blood to recognize the Lord to consider the changes in this dagger. Because this kind of acquired treasure weapon with a machine spirit is not an ordinary magic weapon, it is best to recognize only one master in your life, otherwise, every time you change the owner, its spirituality will be damaged by a point, and the treasure weapon that can give birth to the innate spirit is even more amazing, they choose the master, not just who can take a drop of essence blood as their own, Lu Yi has already had the experience of being deflated in this regard, and the tortoise shell still refuses to recognize him. Helplessly, Lu Yi put it away for the time being, and left it to find a suitable person to send it out in the future, and see if there are any surprises.

Lu Yi continued to move forward, still using this tactic, letting the little monkey and the three of them act as the vanguard, the restless master like the little monkey had already been suffocated in Lu Yi's hands, and finally had such an opportunity to have fun, it was a hard toss! Soon, within a thousand miles, the little monkey caught a seventh-order herbivorous demon beast four-humped camel for Lu Yi, this kind of monster beast is born with a seventh-order, and it will not advance in its lifetime, this beast just lives in the desert, and lives by chewing plants such as sea buckthorn and sand dates, it can eat a large piece of plant at a time, store it in the four humps on its back and digest it slowly, and one meal can often ensure that it will not eat for several months. The beast walks through the desert like walking on the ground, extremely fast, but it is as timid as a mouse, and it runs wild at the slightest disturbance, and it has no attack power, except for its own defense, and is limited to kicking the enemy indiscriminately with its four hooves or biting the enemy with its large mouth without sharp teeth to throw the enemy out. However, even such a simple way of self-defense is not something that ordinary people can bear, and its foot on an ordinary person is enough to trample a person to death, and a bite from it will also cause a fracture, not to mention being thrown out of the way and falling to the ground. The quadrupedary camel has a strong temperament and cannot be tamed, and once it is caught, it does not eat or drink, and gradually loses weight until it starves to death, because its rank is too high and ordinary low-level monks cannot forcibly sign a contract with it, but the high-ranking monks do not look down on it, so few people will do something specifically against it. The little monkey subdued a quadrumodal camel alive, and then used his demon king momentum to suppress it, and then rode on its back and returned to Lu Yi's side with great might.

Lu Yi once again found a suitable place to arrange a soul shaping array, planning to try again to artificially create a tool spirit for the magic weapon, this time he placed the small shield and the four-peaked camel in the array, and after casting the spell to activate the soul shaping array, he quickly stripped off the four-peaked camel's spiritual body, however, Lu Yi found that the spiritual body of the four-peaked camel was very weak, not even as strong as a powerful sixth-order demon beast, such a weak spiritual body was not enough to make it a machine spirit, despite the blessing of the formation, it still quickly dissipated between heaven and earth。 In desperation, Lu Yi had to give up this attempt. He guarded the soul shaping array, and asked the little monkeys to look for prey again, and after the little monkeys left, Lu Yi was bored and began to examine the corpse of the quadruped camel that had no spirit body.

Lu Yi took out the hook and opened the four humps of the quadruped camel* to see what was stored in them, and found that the four humps were all sticky and digested half of the herbaceous plant residues eaten by the quadruped camel, exuding a sour and rotten smell that was disgusting. Lu Yi pinched his nose and played a water spell to wash these things away, and cut off a quadrupent's leg bone to see if it could be used as a refining material, but he was very disappointed to find that just as the spiritual power of the quadrupent camel is weak, its body is not strong, which is equivalent to a better sixth-order material, Lu Yi tried to refine, and found that it has a lot of impurities, and it is very troublesome to purify, so he gave up again in desperation, Lu Yi peeled off the skin of this beast to see if it could be made into soft armor, He even cut off a large piece of meat and tried to roast it, but found that the sour taste of the camel meat was very poor, and the animal skin was rough and lacked toughness.

"Rustle!" Lu Yi was sitting on the ground and was distracted, when suddenly a strange sound came, which startled Lu Yi, and he hurriedly jumped up from the ground with a hook, and flew into the air about ten zhang to look down. I saw that around the corpse of the four-peaked camel that was originally killed by himself, some beetles the size of fingernails suddenly appeared inexplicably, these beetles are also the same color as the gravel on the ground, if they don't move, it's really not easy to distinguish, Lu Yi doesn't know when they came out of the gravel. The beetles gathered more and more, and soon the carcass of the quadrupedan camel was completely covered, and after less than an hour, the corpse of the quadrumedan camel on the ground was gnawed by these unknown beetles, and there was not even a single bone residue left, and the ground was calm again, and the beetles burrowed into the ground after they had eaten their fill. Lu Yi stayed in the air for a while before falling again, he squatted down at the place where the beetle had eaten the corpse of the quadrumedary camel just now, and twisted a very fine particle from the ground and put it in the palm of his hand to observe it carefully.

The small particle in Lu Yi's palm is the same size as the ordinary sand particle, the only difference is that this particle is crystal clear, as if it is transparent, Lu Yi can feel that this fine particle is full of spiritual power, and it is the kind of extremely pure spiritual power, he raised his hand on the ground, and dozens of these particles fell into his hand in an instant, these are the feces-like substances that the beetle just now excreted from his body while eating the corpse of the quadruped camel. Lu Yi had an idea and threw a particle into his mouth, and the particle melted in his mouth, instantly turning into a pure spiritual power, but the particle was too small, and the amount of spiritual power was limited. Lu Yi threw a handful of dozens of particles into his mouth, and the spiritual power transformed into those dozens of particles was already considerable, and this spiritual power could be directly supplemented into the body through oral administration, just like the spiritual liquid condensed by the treasure bottle magic weapon that Lu Yi had unintentionally obtained before, it was more than a little faster than eating the recovery pill and holding the spirit stone in his hand to absorb spiritual power. Could it be that these are the spiritual power crystals that the beetles transformed into the remaining spiritual power in their bodies after eating the corpse of the demon beast? Lu Yi took out a jade bottle and collected all the particles on the ground, the number of spiritual power crystals transformed by the corpse of this four-humped camel was amazing, almost equivalent to the content of more than ten high-grade spirit stones. Lu Yi thought for a while, and then he took off into the air, quickly circled around dozens of miles, and came back with two yellow sheep that had just been slaughtered by him. He took the two yellow sheep again, and the strong smell of blood overflowed, and in a short time, thousands of such beetles appeared on the ground again, and soon they ate the carcass of the yellow sheep, and this time, they expelled a lot of crystalline particles, but the number was much less than that of the four-peaked camel just now. Lu Yi analyzed, firstly, the combined volume of these two yellow sheep is not as large as the four-peaked camel, and secondly, the level of this yellow sheep is a bit low, it is only a third-order demon beast, and there is too little spiritual power in the body that can be transformed into spiritual power crystals. Lu Yi once again got a fifth-order sand lizard demon beast back to confirm his thoughts, sure enough, this time after the sand lizard demon beast was eaten up, Lu Yi got more spiritual power crystals than Huangyang's but less than that of the four-peaked camel, it seems that the number of spiritual power crystals transformed by these beetles is directly related to the amount of spiritual power contained in the demon beast's body. Convinced of this idea, Lu Yi slaughtered several demon beasts in a row to verify it, and finally he confirmed his judgment. Lu Yi went to try elsewhere and found that only the area where he stayed before had this strange beetle, and the range of these beetles didn't seem to be large, probably only a few miles away. Moreover, each time these beetles forage, they return to a fixed area and burrow into the ground, which seems to have their nest.

So, Lu Yi had a new idea.
