When Qin Xu was a teenager, he still watched a lot of martial arts.

Unlike other people's experiences of sneaking behind their parents' backs, his martial arts moved out of his father's study in an open and honest manner.

What's even more different is that in addition to those stories of swords and swords, Qin Xu can also see his father's annotations from the blank space of the book.

Therefore, when Qin Xu saw the silkworm, he couldn't help but think of the silkworm clothes in martial arts, and then compared them together.

Old Master Qin asked Qin Xu's simple and shallow question and asked a rhetorical question.

"What do you mean by invulnerability, invulnerability?"

"Huh?" Qin Xu was asked rhetorically, and suddenly felt that he had asked a stupid question, but he still thought about it seriously and said, "Even if it is ignited, it can't be burned, it can be waterproof, and a sharp sword can't cut it." ”

"Your question is too general, and it's hard to answer. Old Master Qin shook his head and said, "Let's just talk about fire, different burning materials, the burning flame temperature is different, the same material, put into the flame lit by firewood, may be able to maintain the same state, but put in the high temperature of thousands of degrees, it has long turned into ashes." ”

"Not to mention the so-called swords, let's just say that the swords used by the disciples of the foundation building stage and the disciples of the Yuan Infant Stage of the cultivation realm are 108,000 miles sharp. ”

Qin Xumu's face listened to Old Master Qin's careful analysis.

It's terrible to have a master who has been the administrator of the library for hundreds of years.

Old Master Qin helped Qin Xu analyze it, and then he answered Qin Xu's question unsatisfactorily: "With the aura you provide, if you want these little guys to be able to spin silk and weave clothes, and silk can also have the ability you just expected, don't think about it." ”

Old Master Qin told Qin Xu very directly that the alienated silkworm he cultivated, the alienation ability was mainly in the way of weaving cocoons, and it was already Qin Xu's luck to be able to stimulate this ability.

As for the invulnerability of water and fire, invulnerability, and can still be used as body armor, it is more pragmatic to wait for a few generations of cultivation before considering it.

After Old Master Qin finished speaking, he probably looked a little pitiful at Qin Xu's speechless appearance, thought about it and comforted him: "Actually, if someone else beats you, the alienated silk police uniform can still resist a little bit of strength, so that you don't hurt so much." ”

Qin Xu finally figured out that the alienated silkworm that he had cultivated after tossing for a long time was just able to make clothes for himself.

Even if the clothes they make are made of good fabrics and are easy to wear, they are actually just ordinary clothes.

Qin Xu couldn't help but calculate the cost of raising silkworms in winter, and suddenly found that the cost of his police uniform made of alienated silk weaving was probably enough for him to buy an ordinary police uniform to wear until he retired.

In fact, in the process of cultivating alienated mulberry silkworms, Qin Xu secretly had quite high expectations for them.

In his inheritance memory, he happened to see a specially cultivated beast in the Immortal Beast Gate, spinning silk and weaving, the fabric can resist attacks, and in the cultivation realm, it is very popular with ordinary monks.

Seeing this, Qin Xu couldn't help but think of how good it would be if he could also cultivate this kind of strange beast, expand production, and then make clothes that could withstand fire damage, and also defend against swords, becoming light and thin body armor.

It's a pity that judging from the current cultivation effect, the quality of weaving silk cannot meet his expectations.

Although disappointed, Qin Xu had a good mentality and a little bit of a gap, but he quickly adjusted himself.

Glancing at the phoenix-eyed butterfly shaking its transparent blue wings, Qin Xu decided to turn his disappointment into motivation and put all his current energy into the cultivation of the Spiritual Sky Array.

The number of derivative arrays of the Beast Refining Technique was very large, and what Qin Xu had touched was only the most superficial part.

beckoned, letting the crystal blue phoenix-eyed butterfly land on the back of his hand, Qin Xu continued to guide the aura small fish in his eyebrows.

In this practice, Qin Xu remembered the advice and guidance of Old Master Qin very firmly, immersed himself in his mind, and tried his best to control the aura of Xiaoyu'er.

When it was almost dawn, there were still about fifteen minutes before Qin Xu's alarm went off, and the spiritual sky array in the phoenix-eyed butterfly's body was finally completely stabilized.

Qin Xu had the last little aura fish left, and it was only half the size of the last one, and it couldn't swim anymore.

Qin Xu guided the aura little fish back to his eyebrow aperture, and then opened his eyes and stared at the butterfly in front of him.

Originally, the sapphire phoenix-eyed butterfly captured by Master Qin was the most beautiful insect that Qin Xu had encountered so far, and after being washed by the aura, this big butterfly that had opened its wings enough to completely cover Master Qin was only the size of a yuan coin.

Delicate and small like a crystal hairpin, it slowly flapped its wings and stopped on the back of Qin Xu's hand, and there were continuous blue lights surrounding its body.

The degree of delicacy and beauty, even Qin Xu, who doesn't particularly care about the appearance on weekdays, feels like a god-made thing created by a craftsman.

Old Master Qin hugged Lao Huang, floated to the crystal phoenix-eyed butterfly, and pulled its crystal blue wings.

Now that it has become small and delicate, the phoenix-eyed butterfly no longer has the ability to compete with Old Qin's master, it shook its wings, and meekly let Old Qin's hands and feet move, and it is impossible to make Old Qin's master so tired that he needs to hide in the white bones of the divine beast and cultivate for several days before he can show up.

"Let's try it?" Old Master Qin studied for a long time, then turned his head to Qin Xu and said.

As the cultivator of this crystal butterfly, Qin Xu did not need to perform other rituals to obtain the right to use its space.

He only needs to let it rest on his skin, whether it is the back of his hand, or the face and shoulders, and he will be able to use its space.

Old Master Qin asked Qin Xu to try it by himself because although he was able to evaluate and make a rough judgment on this butterfly with spatial abilities based on his rich experience, the only person who really knew the abilities of this spatial beast was its cultivator.

Qin Xu took his army green backpack with his hand.

In the blink of an eye, the backpack disappeared from his hand.

In the blink of an eye, the backpack reappeared in his hand.

Disappear, appear, disappear, appear......

Qin Xu was like a child who had just gotten a new toy, playing happily.

Every time it disappears, and every time it appears, the azure blue streamer on the space little butterfly forms an inexplicably beautiful triangular pattern.

It's like a simplified version of the Spiritual Array.

"Old Master Qin, I probably felt that the space on the little butterfly's body could fit about three backpacks. Qin Xu said excitedly to Old Master Qin.

The size of this space is similar to what Master Qin guessed.

With Qin Xu's ability, as well as the quality of the aura of the Thousand Thunder Running Recipe, as well as the number of spiritual air powder that this phoenix-eyed butterfly has inherently, it can cultivate three space beasts the size of a backpack, although the results are not excellent, but it can also be called middle and upper.
