A few days later, the benefits of the victory of the wandering swordsman began to slowly appear, and the name of "Wanyuan Commercial Bank" was gradually launched.

The successful marketing of the eldest grandson this time seems to have opened up a new world for thousands of people. Thousands of people spend all day in the shop researching how to design more eye-catching goods, how to squeeze out the benefits of the wandering swordsman's fame more extremely, and he is so busy all day long that he completely ignores the eldest grandson. The eldest grandson is also happy to be the shopkeeper again.

It has been more than two months since the half-year assessment, and it is about to be the time for the year-end assessment.

The eldest grandson came to the door of the 112th workshop in the second area of the refining workshop as usual on this day, knocked on the door, and waited quietly outside the door.

"Come in yourself." The owner of the workshop spoke.

Only then did the eldest grandson push open the door and walk in.

After entering the workshop, a heat wave hit, and the owner of the workshop was Wu Lao.

There were some discarded refining materials scattered everywhere, and Wu Lao was holding a finished product and nodding with satisfaction.

The eldest grandson often came to Wu Lao to help him purchase materials, and he became familiar with each other.

"Stinky boy, I said that next time I come, just come in by myself." Wu Lao was still staring at the item in his hand.

"Don't dare to disturb Wu Lao's refining weapon rashly." The eldest grandson said respectfully.

"Hehe, your kid's mouth is quite sweet, but his eyes are not honest, and his mind is also lively, in the past few months, he has stolen from me." Wu Lao turned his head to look at the eldest grandson.

The eldest grandson scratched his head a little embarrassedly, but did not quibble, and nodded sincerely.

"Haha, it's a good thing that young people love to learn, and it's your ability to steal things from me. The old man is also old, and it is best if you can learn all the skills of iron refining. Wu Lao said with a smile.

For such a respected predecessor, the eldest grandson has always had respect, and he was even more awe-inspiring after his words at this time.

"Old Wu, have you succeeded?" The eldest grandson asked.

"Well, it finally worked." Wu Lao said, handing the items in his hand to the eldest grandson.

The eldest grandson rubbed his hands and took the items in Wu Lao's hand.

Through the speculation of the refining materials, coupled with the fact that every time he entered the workshop to peek at Wu Lao's design drawings, the eldest grandson roughly knew that Wu Lao was researching a new material, which was a mixture of materials such as sub-mother iron and soul copper that could store spiritual power, but it was not clear what kind of item could be designed in the end.

At this moment, the eldest grandson looked at the item in his hand, it was a disc-shaped object, the color was brass, which should be the reason for adding soul copper.

"Originally, I wanted to design a flying sword based on the iron of the mother, add basalt to increase its solidity, then add oak to improve its toughness, and finally mix soul copper and Sushen Yuanjing to increase the stability of the spiritual power stored by the warrior on the flying sword, so that the flying sword is not easy to be taken away. But in the end, it still failed, the brittleness of the iron is too high, it is really difficult to be compatible with so many materials, and it often fails in the end. Wu Lao said.

The eldest grandson turned his head to look at Wu Lao, and did not rashly test the characteristics of the items in his hand.

Wu Lao continued: "In the end, I retreated and chose to fuse the soul copper and the mother and son iron together, you can try to store the spiritual power in it and see what changes. ”

The eldest grandson did as Wu Lao said, and probed his spiritual power into the item.

I saw that under the disc in the hand of the eldest grandson, six small flying saucers flew out, rotating back and forth in the market under the control of the eldest grandson.

Wu Lao nodded and said, "This is actually the prototype of the flying sword that I originally planned to design, but now the sturdiness and toughness of these six small discs are far from meeting the requirements of the flying sword. However, you should be able to feel that they are very closely connected with each other, and the consumption of mental energy is very small, and the main thing is that they can be your eyes. ”

The eldest grandson closed his eyes and tried it, and sure enough, the spiritual power carried by these small saucers could well feedback the surrounding situation to himself.

The eldest grandson tried to make the little saucer fly farther, and when it exceeded a certain range, his mental power began to be significantly consumed.

The eldest grandson opened his eyes and frowned, "When you fly out of ten meters, your spiritual power will be significantly consumed, but it is not easy to still be able to maintain a very stable connection with the main body." ”

Wu Lao took the disc in the eldest grandson's hand, nodded and said: "It's true, when it exceeds a certain range, the user's spiritual power will be significantly consumed, but the main reason is that the flight distance is too far, and the separated spiritual power is difficult to carry the weight of the small disc." It's like when you lift a stick for 10 meters and hold a small bowl at one end, and the force consumed to lift a stick for 1 meter with a small bowl at one end is completely different. ”

The eldest grandson nodded. The fusion of iron and soul copper is easy to say, but it is actually an extremely complicated process to really achieve it, the proportion of the mixing of the two materials, the temperature of the flame, etc., these problems can only be solved by continuous experiments and experienced experience.

"I just don't know what the use of this thing can be when it is refined. Forget it, it's not a headache for me, throw it to that guy Wu Dakui and let him study it himself. Wu Lao said.

When the eldest grandson heard this, an idea suddenly appeared in his mind, and he said, "Old Wu, I have an idea. ”

Wu Lao turned his head to look at the eldest grandson, "Oh? What are your thoughts? ”

The eldest grandson pretended to be mysterious and said, "Old Wu, wait a minute, I'll come and tell Old Wu when I have all the things prepared in the afternoon." ”

After the eldest grandson finished speaking, he ran out of the refining workshop.

In the afternoon, the eldest grandson took Si Qin to Wu Lao's refining workshop.

"This is the girl you want to prepare?" Wu Lao looked at Si Qin and asked.

"Si Qin has seen Wu Lao." Siqin saluted.

"Siqin? Are you the daughter of the city lord? Wu Lao asked.

Si Qin nodded obediently.

"Well, a good girl." Wu Lao nodded.

The eldest grandson spoke, "Si Qin took out your golden dew bee. ”

Si Qin nodded and took out the hive of the Golden Dew Bee.

"Elder Wu, the idea I said is to fuse this item you designed with this Golden Dew Bee." The eldest grandson spoke.

Wu Lao was a little puzzled, "How to fuse?" ”

"Si Qin has completely controlled the queen bee of the Golden Dew Bee, and through the queen bee can command the worker bees, which can play a miraculous role in exploration, but the information of the probe can only be fed back to the queen bee through the worker bees, so that the information that can be obtained is relatively simple and general. If you can fuse the Golden Dew Bee with this item you designed, I think it will solve this problem. The eldest grandson explained.

Old Wu brushed his beard in thought, nodded after a while, and said, "Your idea is very good. ”

Got Wu Lao's affirmation that the eldest grandson was a little excited, in fact, when he roughly speculated on the characteristics of the materials developed by Wu Lao, the eldest grandson was thinking about whether there was a possibility in this regard.

If it can be done, Siqin is equivalent to several more pairs of eyes. Siqin also has some expectations.

After having inspiration, Wu Lao and the eldest grandson began to immerse themselves in researching how to design.

"The Golden Dew Wasp is small in size, and it is difficult to tie the iron to it." Wu Lao said.

Because the disc was forged on the basis of the mother and son iron, the two simply called the small disc the sub-iron and the disc the mother iron.

"Well, we want to fuse Zitie and Jinlu Bee perfectly, and we must make sure that Zitie can't affect the Wasp's flight, so as not to limit its speed. In addition, the volume of sub-iron should not be large, otherwise it will lose the characteristics of the small size of the golden dew wasp and the convenience of concealment. The eldest grandson spoke.

Wu Lao frowned, "How can this be done?" ”

The eldest grandson pondered for a long time, he hadn't considered this question before.

Si Qin, who was left to dry, suddenly spoke: "Can you refer to the way of weapon soul empowerment and engrave Zitie on the body of the Golden Dew Bee in the form of runes?" ”

After Si Qin spoke, the eldest grandson's eyes lit up.

"No, if you use this way, Zi Tie will complete the depiction of the runes in a melted form, so that the high temperature Zi Tie can melt the Golden Dew Bee together." Wu Lao said.

"Elder Wu, through my understanding of the Golden Dew Wasp in the past few months, the Golden Dew on its abdomen is its hardest part, and it may be able to withstand the temperature of Zi Tie." Siqin said.

The eldest grandson also looked at Wu Lao, nodded, and said, "Wu Lao, I think you can try." ”

Wu Lao hesitated for a moment, and finally agreed to give it a try.

As soon as he said and did it, Wu Lao quickly melted Zi Tie into a drop of solution.

Wu Lao took out a thin needle again, handed it to the eldest grandson, and said, "Just depict the simplest stability talisman, the old man is dizzy, and I will hand it over to you." ”

The eldest grandson took the needle, gathered his strength and prepared to start.

Wu Lao stopped the eldest grandson and said, "Wait a little longer, the temperature can drop again." ”

The eldest grandson waited, and after Wu Lao nodded, he quickly dipped a drop of iron solution with a needle in his right hand, and then began to depict the golden dew on the abdomen of the golden dew bee.

The eldest grandson's mental power was highly concentrated, and the Golden Dew Wasp was already very small, and it became even more difficult to carve runes on its abdomen.

After a while, the eldest grandson stopped what he was doing, breathed a long sigh of relief, and said, "It's done." ”

Si Qin couldn't wait to control the Golden Dew Bee on the table.

The eldest grandson and Wu Lao both looked at Si Qin a little nervously.

"It worked!" Si Qin said with some excitement.

The eldest grandson and Wu Lao both showed a look of joy.

However, this only proves that this method works, and there is still a lot of work to be done before the final success.

……

The door of the 112 square did not open again until the afternoon of the next day.

Si Qin left the refining workshop with the hive of the Golden Dew Bee a little excited, and she couldn't wait to go back to the other courtyard to try the effect of the transformed Golden Dew Bee.

The eldest grandson and Wu Lao are still in the 112 workshop.

Carving runes for the Golden Dew Bee was a meticulous and laborious task, and the eldest grandson felt a little dizzy at this time.

Elder Wu looked at the eldest grandson and smiled, "It's uncomfortable." ”

The eldest grandson nodded and sat down on the ground.

"Although I didn't follow the little girl to see how it turned out, I think it should have met our previous expectations." Wu Lao said.

"Actually, there is room for improvement." Wu Lao continued.

"Huh?" The eldest grandson turned his head to look at Elder Wu.

"I designed a disc that not only probed the scene, but also recreated the scene." Wu Lao said.

"You mean...... The moon in the mirror? "The eldest grandson immediately thought of the moon in the mirror that had been refined by the Yuehua clan.

"The moon in the mirror can only be refined by the Yuehua clan, not only because the runes that give it soul are not disclosed, but also because the Yuehua clan's exercises absorb the essence of Haoyue, and the scene presented by the moon in the mirror after their true qi is soul-empowered, which is incomparable to the demon spirit beads and jade light slips that are prevalent on the market today." Wu Lao said that the Demon Spirit Bead and the Jade Light Room he was talking about are both commodities that the mainland now uses to record pictures

"Are you saying that the mother iron can also record the picture after giving the soul?" The eldest grandson asked.

"That's right, so that the picture detected by the Golden Dew Bee can not only be seen by Si Qin, but also by the people around him through the mother iron." Wu Lao said.

The eldest grandson's liver trembled, and a bold idea came to his mind again.
