After Li Mu felt that he had made a windfall, his joy quickly calmed down, and he quickly shifted his focus away from these two 'medicine' fields, after all, these spiritual 'medicines' couldn't run, so Li Mu didn't plan to pick them immediately.

Li Mu slowly walked to the center of the spiritual room, he looked up at the transparent light mask above his head, if he guessed correctly, this transparent light mask should be related to the breeding of spirit beasts.

Li Mu circled around the white 'jade' array under the transparent light cover twice, trying to see if he could see some clues, but with his attainments that could almost be regarded as blank in the formation, he circled around the white 'jade' array more than a dozen times, and he didn't see what the mystery of this white 'jade' array was there, and he didn't even recognize the materials that arranged this array.

Because he couldn't see the subtlety of this array, Li Mu rolled his eyes under some entanglement, and then released a black-armored god-killing insect from a spirit beast bag on his waist.

This is a black-armored eight-star god-killing insect, and it is also the 'essence' of Li Mu's remaining less than thirty god-killing insects, after all, those who can follow Li Mu's conquest and survive until now are more or less stronger than god-killing insects of the same level.

After releasing the god-killing insect, without waiting for Li Mu to issue a spiritual command, the god-killing insect let out a hissing sound in mid-air, and then directly drilled into the transparent light mask in front of him, as if he had been 'lured' and 'confused' by something that was difficult to resist, so that Li Mu, as its owner, couldn't help but sigh.

The Godslayer Worm flew very fast, and almost in the blink of an eye, it rushed into the transparent light mask.

As the god-killing insect rushed into the transparent light shield, the white 'jade' array platform floating in mid-air under the transparent light mask suddenly erupted into a dazzling white light, and then a 'refined' vitality that was pure to the extreme emanated from the array platform, turning into a white 'color' vitality light pillar the size of a bucket in the center of the array platform, and just 'shot' into the transparent light mask floating in the air above the array platform.

The reason why the transparent light mask is said to be transparent is because it does not carry any color 'color', if it weren't for Li Mu's ability to sense the faint vitality 'wave' movement it emitted with his spiritual sense, he really wouldn't have been able to discover its existence;

These white 'colored' dao patterns exude a mysterious and mysterious aura, at least with Li Mu's current spiritual power and perception of the vitality of heaven and earth, he can only look up at the aura emitted by some white 'colored' dao patterns.

"Hiss !!"

With the appearance of the white 'colored' pattern on the transparent light mask, the god-killing insect that had just flown into it immediately let out a piercing hissing sound, Li Mu thought that this was the god-killing insect in danger at first, but when he communicated with the god-killing insect in the light mask with the spiritual sense mark, he found that he was making a fuss, and the reason why the god-killing insect in the light mask hissed was not because of pain, but because it was too comfortable to scream.

Carefully staring at the god-killing insects in the transparent light mask, Li Mu soon discovered the mystery, under the supply of the 'refined' pure vitality of the array below, the transparent light mask in mid-air was filled with 'refined' pure vitality, these vitality was tantamount to a great supplement for the god-killing insects, and it was easy for the god-killing insects to absorb it.

After absorbing a large amount of 'essence' pure vitality, Li Mu discovered that the god-killing insects, which were originally only at the level of eight stars, were actually approaching the Black Armor Nine Star at an extremely fast speed.

If the god-killing insect wants to advance, it is generally to devour the materials that are beneficial to it, and absorb the energy required for its own advancement from it, which is the same as the cultivator absorbing the vitality in the refining yuan crystal, the difference is that the god-killing insect does not devour everything, basically most of the materials can be devoured and absorbed, which also leads to the god-killing insect's fierce reputation shocking the ten thousand worlds, ranking third on the list of strange insects in the ten thousand worlds.

And the god-killing insect is the same as the cultivator, as the level gets higher and higher, the energy to be absorbed is also more and more, only in this way can it be advanced, and the purity of the vitality in this transparent light mask is so terrifying at the moment, which naturally leads to the rapid entry of the god-killing insect.

Li Mu saw that the black armor god-killing insects were not in danger, and immediately released the remaining more than twenty god-killing insects, as soon as these god-killing insects were released, just like the black-armored god-killing insects in this light mask, they rushed into the transparent light mask without Li Mu's order, and then frantically absorbed and devoured the vitality in it.

"It turns out that it is for this reason that I can have such a great effect on the advancement of spirit insects and spirit beasts, I don't know if I can..."

Looking at his god-killing insect, enjoying the 'essence' pure vitality in the transparent light mask like a fish in water, a very bold thought flashed in Li Mu's mind, the corners of his mouth twitched, and then he ran his True Yuan Gong Great Brahma Gong, and inhaled the 'Jing' pure vitality in the transparent light mask, and a fist-sized white 'colored' vitality was forcibly ingested by him from the light mask.

After taking out a ball of vitality, Li Mu put his palm on top of this white 'colored' vitality, wanting to use exercises to ingest it into his body to see if he could absorb and refine it.

With the operation of Li Mu's Great Brahma Gong, the white 'colored' vitality mass in front of him was quickly absorbed into his body, at first Li Mu felt very useful when he saw this, but when he was ready to absorb and refine with the Yuan Spirit, these white 'colored' vitality suddenly 'chaotic' in his body uncontrollably, and the true yuan in Li Mu's body was 'chaotic' and 'chaotic', and he spit out a mouthful of 'essence' blood on the spot.

In his opinion, even if he couldn't accelerate his true yuan cultivation, it was good to be able to improve the strength of his 'flesh' body, but after Li Mu tried to absorb and refine this vitality with the power of his 'flesh' body, he soon 'revealed' an extremely ugly 'color' face.

What disappointed Li Mu was that not only his Yuan Spirit could not absorb these Yuan Qi, but also his 'flesh' body could not absorb it at all.

Only then did Li Mu clearly realize that the vitality condensed in the array in front of him should only be suitable for the absorption of spirit insects and spirit beasts, and for the cultivators of the human race, it would be harmless and not beneficial.

"It seems that this spirit breeding room is far from being as simple as I imagined, too, for demon clans such as spirit beasts and spirit insects, to advance sometimes it is not possible to succeed by simply devouring the vitality, but also to be able to quickly refine and absorb, seeing that these god-killing insects can absorb and refine the vitality so quickly, I think these vitality must have been specially processed by this array!"

After thinking for a moment, Li Mu shook his head with a wry smile, he felt that he was too greedy, but Li Mu didn't have much disappointment, he knew that the retreat room must also have the mystery of accelerating the cultivation of human cultivators, but he only found the magic of healing and came out.

"Good place, if the god-killing insects in my hand are enough, with the magic of this soul breeding room, it is not impossible to create a large number of high-level god-killing insects!"

Li Muzheng was thinking that the god-killing insect in his hand was not enough, and suddenly he frowned, and then took out a spirit beast bag, and took out a god-killing insect from it that was three points larger than the ordinary god-killing insect.

This is a black beetle god-killing insect, it can be found that its abdomen is slightly bulging, it is Li Mu in the Heishi Pingding Mountain that day, those who were catalyzed by the fire of the poison source ** produced a 'crossing'.

After Li Mu took out the god-killing mother worm, he sent it into the light shield in the air in front of him with the power of the true element.

After this god-killing mother worm entered the transparent light mask, it trembled all over, and actually woke up from its deep sleep, it first looked around, and then quickly absorbed the pure vitality of the 'essence' in the transparent light mask.

Under Li Mu's careful observation, he found that after absorbing a large amount of 'essence' pure vitality, this god-killing mother worm did not change much in itself, but its abdomen had a tendency to become larger.

Looking at the unharmed god-killing mother worms, Li Mu quickly took out all the remaining seventy or eighty god-killing mother worms in his spirit beast bag, and then sent them into the transparent light mask
