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

After taking out the Sword of Inquiry, he brought a trace of spiritual power, and he used the Sword of Inquiry to open the stone.

However, the sharpness of the Sword of Sin is far from comparable to those special knifes for cutting materials. This stone that seems to be as hard as a rock was instantly cut off several places when the Sin of Sin of Sin, and it became powder as soon as it was cut off.

This scared Qin Feng and hurriedly looked through the powder that fell to the ground. After confirming that there were only stone debris inside, he continued to start the material with confidence.

Then, the sharpness of the Sword of Juewen was released, and in a few seconds, a strange light had already been released from the stone.

"Dragon Teeth Amber?"

After Qin Feng broke the stone residue wrapped around the treasure with his sword, he picked up the crystal amber that was about half the size of a finger and whispered the words written on the attributes beside him.

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

"Mom, can I eat this?"

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

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

Judging from the attributes of the dragon teeth amber, its function is to forge an ornament-type magic weapon to enhance the strength and deterrence of the user's spiritual power, but this is also like a waste of money for Qin Feng, so it's okay to not.

In fact, it is not just this dragon-tooth amber. Among the dozen treasures before, there are quite a few that Qin Feng doesn’t need at all.

This is the first time that Cang Xun reacted.

"But, what should I call my mother if I don't call her mother?"

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

Qin Feng sighed and said, "Do you understand when calling me brother in the future?"

"Um..." After Cang Xun thought about it for a moment, he turned into a light spot and turned into a human form in front of Qin Feng.

"Brother~Brother."

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

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

"That won't work. You can't just call your name. The book says that Yu Li is not in line." After thinking about it, Cang Xun said, "If that's the case, I'll call you... Brother Qin Feng from now on."

Although this title still makes Qin Feng feel a little uncomfortable, it is better than before.

"That's it."

As he said this, Qin Feng handed the dragon-tooth amber in his hand to Cang Xun.

However, Cang Xun did not reach out to pick it up, but opened his mouth and put Longya Amber and Qin Feng's fingers in his mouth.

Originally, this was nothing.

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

But this did not make Qin Feng feel the pain, but instead it was another really unspeakable feeling.

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

On the other hand, Cang Xun let go after he noticed Qin Feng's strangeness, and the dragon-toothed amber had already completely melted in her mouth and was directly absorbed into her body.

As for Qin Feng, after Cang Xun let go of his mouth, the roast on his hands disappeared instantly, and replaced by a cool and comfortable feeling that reached the bottom of his heart.

And at this moment, although his hands were not strange from the outside, in Qin Feng's perception, they were almost no longer on the same level as other parts of his body.

In the palm of his hand, every inch of his muscle movement was filled with power that almost made Qin Feng difficult for a moment.

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

In an instant, a surge of spiritual power penetrated through the meridians and quickly reached the palm of the hand.

At this moment, the spiritual power fluctuations 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 had this palm now, even the warriors at the ninth level of the Spirit Forging Realm would not be able to withstand it.

"hiss……"

But just as Qin Feng was shocked and was about to withdraw his spiritual power, a numbness caused the spiritual power in his palm to quickly dissipate, and his whole hand and his entire arm fell into the numbness that had been done for a while ago.

It took him a long time to recover.

But at this time, his heart was filled with a sense 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 other things 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 knew that she would definitely not lie, so he did not continue to ask questions.

While shocked, he also felt that his palms had changed like they had just now, and they must have a close relationship with Cang Xun.

But if he was asked to try again, he wouldn't be sure if his hands would be ruined next time, so he didn't dare to try again.

On the other hand, he also tried to ask the system why, but the system still did not tell Qin Feng on the grounds that the permissions were insufficient.

"It seems that I can only wait until I go back and ask Yun Hao to be defeated."

After thinking about it this way, Qin Feng temporarily put this matter aside.

Then he began to open two other pieces of stone marked with question marks.

Immediately afterwards, Qin Feng spent a whole morning locking himself in this not-so-large room, and kept sitting in the process of opening materials.

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

In front of him, there was only the last stone, which was about the size of two palms.

Qin Feng raised his sword and fell. In just a flash of a few swords, most of the stones had turned into waste residue, and a dim black halo was emitting from it.

After two consecutive knifes, he completely cut off the remaining stone, and the slightly more black iron was displayed in front of Qin Feng with a luster.

After picking up the black iron and scanning the room with scraps of stones, he sighed in his heart.

"In one morning, the foundation of cutting materials has become deeper and deeper." After he complained about himself, he blew a sword and piled up all the waste in one place, but it was as big as a bed.

After cleaning up this simple thing, he put the black iron in his hand back on the desk.

Then, he put all the black iron he had made before on the table.

Although the strength of the first, second and third grade black iron is not weak, it is used in computers. At least theoretically too fragile, and it is easy to have a series of problems.

Qin Feng roughly estimated the fourth grade and above black iron, which was 25 or six kilograms in total.

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

Qin Feng, who now has some understanding of forging, also roughly estimates that if he uses these black irons to build a computer motherboard, he should be able to create nearly 60 motherboards.

However, in addition to motherboards, there are also graphics cards, CPUs, etc. Even though the world's forging technology far exceeds the manufacturing technology of the earth, making these things can save a lot of materials, but these 25 or six kilograms of black iron can only be completely created to create more than twenty complete computers.

Moreover, Qin Feng now only has a global theoretical basis in his mind, and there is no precedent for forging a "computer" in this world, so at the beginning, it will be a time-consuming and labor-intensive and even material-consuming stage.

After he felt certain, Qin Feng finally sighed in love.

"The remaining black iron still has to find a way to get all the remaining black irons." After receiving all these black irons, he set off to go downstairs and leave the inn.

Although we have to find a way to get it all, the solution Qin Feng could find was nothing more than continuing to bet on stones or buying from the gambling stone shop.

The price of first-grade black iron is not high, two or three spirit stones per kilogram, two or three black iron is four or five spirit stones per kilogram, and three-grade black iron only requires five or six spirit stones per kilogram.

However, the Xuan Iron, which is less than the fourth grade, cannot create a computer like the one in Tianyun City.

Although the third and fourth grades are only one grade, the prices are very different.

The value of a pound of fourth-grade black iron is even as high as eighteen spirit stones or even twenty spirit stones.

Thinking of this in my heart, Qin Feng had already walked downstairs.

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

"The current black iron is just some raw materials. If you want to forge things like motherboards, you still need to find some craftsmen to help you."

Walking on the street, Qin Feng thought so.

Since that's the case, he probably had to live a very compact life in the next four months.

It is precisely because of this that Qin Feng did not have the time to waste it any more.

He thought to himself that when the Yuanyang Chamber of Commerce is over, he should devote himself to the work of building computers.

Whoosh.

But at this moment, Qin Feng suddenly noticed two figures flying past the eaves beside him.

And immediately followed, after detecting something strange, he activated the range perception and immediately realized that he was surrounded by many people.

Even among the pedestrians around, many people's eyes were focused on him.

Obviously, someone was targeting him.
