When no more black gas rose on the corpse, Mao Rui stopped the entry of the magic trick and was about to leave a brand, but unexpectedly there was a muffled "bang". The blood corpse that had been refined exploded entirely. Mao Rui, who is the closest, if it weren't for the bad smell and the constant maintenance of the shield on his body, would definitely be drenched red by the minced meat.

With a wave of his hand, he removed the flesh from the mask. Frowning and thinking about it, he took out the jade slip that recorded the refining of the blood guard, and compared it with his own behavior.

Half an hour later, Mao Rui found several mistakes in his own right. A bloody corpse was removed from the blood pit and the refining began again.

"Bang"

It's the same corpse, it's the same muffled sound, it's the same layer of light, it's just the order.

This time, it was not compared with Yujian, because there were no new problems, and the problems found before had not been overcome. Mao Rui sat there, thinking about the solution, this sitting was half a day, and by the time he opened his eyes, it was already dark. Taking out a solar-charged lamp and hanging it on the canopy, Mao Rui began refining again.

It took five days to blow up twenty-two corpses, and during this time, I don't know how many mistakes were found and corrected, and Mao Rui finally succeeded in leaving a mark.

Controlling the blood guard, because it has just been refined, it is still very fragile. Mao Rui didn't test its power, just made it do a few simple movements. Since it is refined by itself, there is no trace of jerkiness in the operation.

Finally succeeded in refining the Blood Guard, Mao Rui, who had been failing in the past few days, had a flash of joy on his face. But it was completely expected, without a trace of excitement. A refining method like his, which discovers a mistake and changes it immediately, as long as the reference method is correct, success is inevitable, and it is only a matter of time.

Rubbing his temples that were a little sore, Mao Rui had time to look at the finished blood guard in front of him with eyes full of appreciation. The whole body of the blood guard is blood red, which is originally flesh and blood, but it looks like it has a metallic color, which makes people look at it at a glance and produce a feeling of solidity. The only fly in the ointment is that there is a huge opening on the neck, and the head on it seems to fall off at any time.

Mao Rui didn't care about the mutilation of the corpse, this thing is not for ornamentation, as long as it can be used, it doesn't matter if it looks good or not. At this point, it's not actually a matter of personality, it's mainly because of looks. Mao Rui can be said to be quite ordinary, in his cognition, handsome is just a little stronger in terms of the ability to rub rice, and it is still the kind of soft rice that can stick to the teeth. And he likes to eat harder and dry rice when he is young. So he took this reason and successfully hypnotized himself, constantly telling himself that it was useless to be good-looking.

Putting this blood guard into the space bag, Mao Rui began to refine it again. Because all the problems that will be encountered have been solved, the speed is much faster, and even the success rate, only one or two out of ten will fail.

A month later, Mao Rui had successfully refined one hundred and forty-six blood guards, and there were no more complete corpses in the blood pit, and as for the remaining parts, such as a head, an arm, or even half a body, Mao Rui really couldn't think of any use after refining.

Take out all the 146 corpses and arrange them neatly together, looking at the red patch in the past, plus the bloody gas it brings, it is still quite imposing. In particular, the first three were made from the corpses of the Tomb Brothers and the Tiger Leader. Because he was a cultivator before his death, no matter the degree of hardness, the speed of action, the strength of his attack, or the concentration of blood qi, he was much stronger than the other one hundred and forty-three bodies.

When the time came, after being nourished, Mao Rui believed that these one hundred and forty-three blood guards could compete with monks who practiced qi at around the fifth or sixth level. And those three powerful blood guards, according to Mao Rui's estimate, even if they can't fight against the monks who have perfected their Qi cultivation, they are absolutely no problem to contain them. This is still the case when the blood guard fights the monk alone, if a group fights one...

Mao Rui thought of this, and he laughed strangely.

Some materials are still needed to nourish the blood guard, but there are no ones at present, so we can only wait for later. Mao Rui opened up a separate 'space bag' for the blood guards, and put one hundred and forty-three ordinary blood guards into it first. He cut down half a big tree, cut it into three pieces, hollowed out the inside, and made a simple coffin, first put the three high-level blood guards in, and then put the coffins into the blood guards' exclusive 'space bag'.

Looking at the blood in the blood pit, Mao Rui thought about it, although he thought that the blood was useless, and with the shameful idea of wasting it, he once again opened up a separate 'space bag' and sucked the blood in the blood pit into it.

This is Mao Rui, Mao Rui with super high space talent, Mao Rui who can open a few if he wants to open a few space bags, if it is replaced by someone else... Just think about it.

The blood in the pit was sucked away, revealing the severed remains of the limb at the bottom. Mao Rui watched for a long time, and finally three fireballs flew out and burned them all. No matter how much you save, you can't keep everything. Even though Mao Rui's nerves are a little big, he still has a bit of a diaphragm when he puts away his arms, thighs and even intestines.

After doing this, Mao Rui took out a golden skeleton from the 'space bag', which was left behind by the 'Burning Heaven Dao Man' after his death. This skeleton has cultivated the 'Burning Heaven Transformation Bone Determination', and judging from its color, it has still cultivated to the third level realm 'Golden Bone Realm', and has cultivated to perfection.

As the new cultivator of the 'Burning Sky and Bone Transformation', he was completely aware of the power of cultivation. To put it mildly, even if you don't have to refine it, you can directly hold it in your hand and move it, you can directly blow up the gas refining period. Even if you build the foundation, although you may not be stoned to death, you will be beaten to the point where you can't do it, that's for sure.

Such a skeleton that could not leave the slightest trace on it when attacking with all its might. Mao Rui would not be stupid enough to think that putting it in a blood pit and refining it with ordinary chicken blood and duck blood would be effective with ordinary corpses.

Take out a large bucket and pour a whole bottle of anticoagulant liquid into the bucket, then cut your wrist and drip blood into it. Mao Rui planned to refine this skeleton with his own blood that was rich in spiritual energy. When he felt dizzy, Mao Rui stopped the wound and sat aside and waited for the blood to recover on its own.

When the blood has recovered, cut the wrist again. In this way, eight days passed in a row, and most of the barrels of blood were accumulated. This is also due to Mao Rui's cultivation of the blood method, otherwise not to mention ordinary people, even other cultivators, would not be able to withstand this amount of bloodletting.

After waiting for the blood volume to recover again, Mao Rui took out a large amount of potions and powders, which were enough to refine ten blood guards in normal times, but they were all poured into the bucket by Mao Rui. Then put the golden bones in. Then his hands moved, and one after another spells entered it.

Counting the time to recover the aura, it took ten full days before Mao Rui stopped his gestures. The bones were fished out of the air, and the bones at this moment were no longer golden yellow, nor blood red, but showed a noble golden red, shining in the sunlight with charming brilliance.

Mao Rui did not immediately remove the impurities, but kept pinching his hands and laying layers of shields on his body. Three more defensive artifacts were taken out and hovered outside the shield. No wonder Mao Rui would be so careful, this skeleton is extremely hard, if the refining fails, the skeleton will burst, it is not as simple as the flesh and blood that was drenched with a shield before.

After doing all kinds of protection, Mao Rui began to play one trick after another. An hour later, there was not the slightest black gas coming out of the bones, Mao Rui in the pinching recipe couldn't help frowning, but he quickly stretched out, and comforted in his heart: "It's okay, force out the impurities inside, the longer it takes, the higher the quality of the bones, and the previous three high-level blood guards took a lot more time than the others." At this time, Mao Rui's heart was still quite calm.

But three days later, Mao Rui, whose aura had recovered six times, could no longer maintain the calm he had before, stopped his movements, frowned and pondered.

"Is it because the Burning Heaven Dao has already refined the impurities in the bones before I was born, or is it because I can't refine the impurities in it with my current means?"
