Qin Feng first picked up one of the three question mark attribute stones.

After taking out the sword of sin, with a trace of spiritual power, he used the sword to open stones.

However, the sharpness of the sword is far from being comparable to those knives that are used for cutting, and this seemingly hard rock-like stone, when the sword is lightly touched, it is instantly cut off in several places, and it becomes powder as soon as it is cut.

This startled Qin Feng, and he hurriedly went to look at the powder that had fallen to the ground, and after confirming that there were only stone chips in it, he continued to open the material with confidence.

Then, with the sharpness of the sword, in three or two clicks, a strange light was already released from the stone.

"Dragon's Tooth Amber?"

After Qin Feng shattered the stone residue wrapped around the Heavenly Treasure with a sword, he picked up the crystal amber, which was only about half the size of a finger, and whispered out the words written on the attribute on the side.

At this time, Xiaolong Cangxun suddenly poked his head out of Qin Feng's neckline.

"Mother, can you give me this?"

Cang Xun's voice sounded directly from Qin Feng's heart.

And Qin Feng looked down at Cang Xun and said, "If you can get rid of this bad habit of calling me 'mother', I will give this to you." ”

Judging from the description of the attributes of this dragon tooth amber, its function is to forge into a jewelry-type magic weapon, which is used to enhance the strength and deterrence of the user's spiritual power, but this is also like chicken ribs for Qin Feng, don't do it.

In fact, it's not just this dragon tooth amber, among the more than a dozen heavenly treasures before, there are also a considerable number of them that Qin Feng doesn't need at all.

It's just that Cang Xun has a reaction, and this is the first time.

"However, if you don't call your mother a mother, what should you call it?"

Cang Xun raised his head, put his small mouth against Qin Feng's chin, and asked.

Qin Feng sighed, and said, "Call me brother in the future, do you understand?"

"Hmm......" After thinking about it for a while, Cang Xun turned into a point of light and transformed into a human form in front of Qin Feng.

"Brother~Brother. ”

The exclaimed and coquettish tone made Qin Feng tremble slightly, and he felt goosebumps all over his body.

"Let's call me Qin Feng. Qin Feng stopped.

"That's not okay, you can't just call your name, the book says it's not in line with etiquette. After thinking about it, Cang Xun said, "Otherwise, I will call you in the future...... Brother Qin Feng is fine. ”

Although this title still made Qin Feng a little uncomfortable, it was better than just now.

"So be it. ”

Saying this, Qin Feng handed the dragon tooth amber in his hand to Cangxun.

But Cang Xun didn't reach out to pick it up, but directly opened his mouth and took the dragon tooth amber and Qin Feng's fingers in his mouth.

Originally, there was nothing about it.

But in the next moment, Qin Feng's entire arm seemed to be scorched by flames, and every trace of nerve seemed to be violently and hotly damaged.

But this did not make Qin Feng feel pain, but it was another taste that was really indescribable.

Although it was unbearable, it made Qin Feng reluctant to push Cang Xun away.

On the other side, Cang Xun only let go of her mouth after noticing Qin Feng's abnormality, and the dragon tooth amber had already completely dissolved in her mouth, and was directly absorbed into her body.

As for Qin Feng, after Cang Xun let go of his mouth, the roasting on his hand disappeared in an instant, and was replaced by a burst of coolness that went straight to the bottom of his heart.

And at this moment, although his hand didn't look anything unusual from the outside, in Qin Feng's perception, it was almost not at the same level as the rest of his body.

Between the palms of his hands, every inch of muscle movement was filled with a force that was almost uncontrollable for Qin Feng for a while.

With a thought in his heart, he mobilized the spiritual power in the fire spirit vein.

In an instant, a surging spiritual power passed through the meridians and quickly reached this palm.

At such an instant, the spiritual power fluctuation in Qin Feng's hand reached a height that had never been reached before.

Although he couldn't try it himself, he felt that if he was holding this palm now, he was afraid that even the martial artists of the Nine Realms of the Spirit Refining Realm would not be able to resist it at all.

"Hiss......"

But just when Qin Feng was shocked in his heart and was about to withdraw his spiritual power, a burst of numbness caused the spiritual power in his palm to quickly escape, and his entire hand, along with his entire arm, fell into the numbness that he had done before.

It took him a long time before he barely recovered.

But at this time, his heart was already filled with a kind of surprise.

"Brother Qin Feng, what's wrong with you?"

Cang Xun tilted his head and asked Qin Feng.

Qin Feng looked at Cang Xun and asked, "Did you do anything else when you were eating that piece of dragon tooth amber just now?"

"No. ”

Cang Xun shook his head and said so.

Seeing this, Qin Feng also knew that she would definitely not lie, so he didn't continue to ask.

In addition to the shock in his heart, he also felt that the change in his palm like just now must be inextricably linked to Cangxun.

It's just that if he wants to try again, he is not sure whether he will let his hand be wasted next time, so he does not dare to try again.

On the other hand, he also tried to ask the system why, but the system still didn't tell Qin Feng on the grounds of insufficient permissions.

"It seems that I can only wait until I go back and ask Yun Haozhong. ”

Thinking about it like this, Qin Feng put this matter behind him for the time being.

He then proceeded to open two more stones marked with question marks.

Immediately afterwards, Qin Feng spent a whole morning locking himself in this not too big room, and sat down with the complicated process of cutting materials.

When four hours passed, and the day was noon, Qin Feng had already turned all the stones in the room into debris.

In front of him, only the last stone remained, and this stone was about the size of two palms.

Qin Feng raised his sword and fell, and in just a moment, under the three or two swords, most of the stone had already turned into waste slag, and a faint dark black halo was also emitted from it.

After two more knives in succession, he completely cut off the remaining stones, and the piece of dark iron, which was a little more than a catty, was displayed in front of Qin Feng with a lustre.

After picking up the piece of black iron and glancing at the stone waste that filled the room, he sighed in his heart.

"After a morning's work, the foundation of this cutting material is getting deeper and deeper. After he complained to himself, he blew a sword wind with a sword in his hand, and piled up all the waste in one place, but it was already the size of a bed.

After cleaning up so simply, he put the dark iron in his hand back on the desk.

Then, he put all the dark iron he had opened before on the table.

Although the strength of the first, second and third grades of dark iron is not weak, it is too fragile, at least theoretically, when used to make computers, and it is easy to have a series of problems.

As for the fourth-grade and above-grade Xuantie, Qin Feng roughly estimated it, and there were twenty-five or six catties in total.

As for the role of these dark irons, it is obvious that they will be used by Qin Feng to make computers.

And now Qin Feng, who already has some understanding of the forging technique, also roughly estimated that if he used these dark irons to build computer motherboards, he should be able to create nearly sixty motherboards.

However, in addition to the motherboard, there are also graphics cards, CPUs, etc., even if the craftsmanship of this world's forging technology far exceeds the manufacturing technology of the earth, and a lot of materials can be saved in manufacturing these things, but these twenty-five or six catties of dark iron can only be used to create a complete twenty or so complete computers.

Moreover, now Qin Feng only has the theoretical basis of the overall situation in his heart, and there is no precedent in this world for forging a 'computer' with forging techniques, so at this very beginning, it will definitely be a time-consuming, laborious and even material-consuming stage.

After making up his mind, Qin Feng finally sighed.

"I still have to find a way to get the rest of the dark iron. After receiving all these dark irons into the class full of all kinds of heavenly and earthly treasures, he set off to prepare to go downstairs and leave the inn.

Although he had to find a way to make it up, all Qin Feng could think of was to continue gambling on stones, or buy them from the gambling stone workshop.

The price of a first-grade Xuantie is not high, two or three spirit stones are a catty, the second-grade Xuantie is a catty of four or five spirit stones, and the third-grade is only five or six spirit stones a catty.

However, less than four grades of Xuantie could not build a computer like the one in Tianyun City.

Although there is only one difference between the third and fourth products, the price is far from the same.

The value of one catty of four-grade Xuantie is even as high as eighteen spirit stones or even twenty spirit stones.

Thinking like this in his heart, Qin Feng had already walked downstairs.

After asking the shopkeeper to take time to take care of his room, he left the inn and walked out onto the street.

"The current dark iron is just some raw materials, and if you want to forge something like a motherboard, you still need to find some craftsmen to help. ”

Walking on the street, Qin Feng thought so in his heart.

And since this is the case, then he will probably have a very tight time in the next four months.

It is precisely because of this that Qin Feng has no effort to waste at this time.

He thought to himself that when the matter of the Yuanyang Chamber of Commerce was over, he should devote himself to the work of building a computer.

Whoosh.

But at this moment, Qin Feng suddenly noticed that on the eaves beside him, two figures flew by.

And immediately after, after noticing the abnormality, he turned on the range perception, and immediately realized that he was surrounded by many people.

Even among the pedestrians around him, there are many people whose eyes are focused on him.

Obviously, who is he targeted.

With a certain heart, his steps are swift out.

Seeing that Qin Feng was about to flee from here, one of those people finally couldn't bear it anymore, pulled out his sword and stabbed at Qin Feng extremely quickly.

At this time, Qin Feng's figure flashed, and he directly dodged the sword.

It was precisely because of such a movement that those passers-by who did not know it immediately retreated one after another, and basically exposed all those who were paying attention to Qin Feng.

There were probably nearly twenty people, and there was even a powerhouse of the Ning Yuan Realm among them.

With a certain heart, Qin Feng immediately flew out.

At first, he stepped directly out of "Fuyao Footwork", but the other party seemed to have been prepared, and the people chasing him stubble after stubble, making it difficult for him to shake off even if he turned into the wind.

After that, his physical strength retreated slightly, so he could only stop the "Fuyao Footwork" and use two sets of body methods to work together.

But when he ran full speed, it became more and more difficult for him to shake off the gang.

"This way!"

Suddenly, a hand stretched out out of nowhere and directly pulled Qin Feng into a small alley.

Immediately after, the other party hugged Qin Feng with both arms, making Qin Feng only feel that there were two soft things in front of him, and a fragrance that made him feel familiar was even more familiar to his nose.

Without looking at his face, Qin Feng immediately knew that this person was Mi Yao.

And because of the special magic weapon on Mi Yao's body, it was naturally hidden along with Qin Feng's breath that was close to her.

Those who were chasing Qin Feng also scattered to look for Qin Feng because Qin Feng's aura and figure suddenly disappeared.

Finally, it should have escaped a catastrophe.
