Dongfang Ziyan was invited to sit on the high stool behind the counter, and the junior apprentice poured him a cup of tea, Dongfang Ziyan felt a little inexplicable, and he was a little overwhelmed to sit on the stool for a while.

"This boy has extraordinary knowledge, how can he recognize this black box cannon?" The old shopkeeper wiped the oil stains on his hands and sat down on the stool opposite Dongfang Ziyan.

"This ......" Dongfang Ziyan was speechless, he didn't know whether to tell the truth or not, because this black box cannon was invented by him after all, although he didn't know why there was such a thing in the underground store of Starmoon City.

"This black box cannon is a hidden weapon that integrates mechanical technology and mechanism structure, and its effect is so powerful that it can be called a weapon, and it is a rare alchemy mechanical boutique." The old shopkeeper took off the black box cannon from the shelf, touched the black carvings on it and said slowly.

"I've just heard of it, I've just heard of it......" Dongfang Ziyan echoed and said, then smiled unnaturally, "Is this black box cannon made by you, the old shopkeeper?" What a skilled craftsman, admired by the younger generation. ”

"How dare I dare, how can I make such a rare thing as an old man so stupid, this is what someone else bought for me. This black box cannon is from the hands of Dongfang Ziyan, the first mechanical alchemy genius of the current human race. The old shopkeeper waved his hand and said.

When Dongfang Ziyan heard this, he first laughed stupidly, and then asked, "First mechanical alchemy genius?" Is Dongfang Ziyan so powerful? ? ”

I saw the old shopkeeper smile indifferently, and then put the black box cannon back on the shelf, took off the goggles on his head and then spoke, "Although I haven't seen the second son of the Dongfang family, his reputation is very spread in the world, it is said that the second son of the Dongfang family is proficient in the six styles of fire and demons, all kinds of strange arts, and is also well-read, rich and rich, is a genius, and is a heroic boy, not to mention the big trouble in the river basin Babel Tower, just the alliance holy war more than a year ago and the floating island incident not long ago, is enough to make him famous all over the world, in our industry, hehehe, except for one god, two saints and three emperors, it is this ghost who is the most famous. ”

"Oh, I have heard of one god and two saints in this mechanical alchemy field, the so-called one god is the divine craftsman Lu Ban, and the two saints are the ghost god craftsman Tie Qiusheng and the Jia Luo Ling Emperor Holy Phoenix, as for Tie Qiusheng's eldest disciple Mechanical Emperor Frey Heracross, and Ji Yue, a subordinate of the Holy Phoenix, although their strength can be called 'emperor', these two have been dead for many years, and they have never heard of a third 'emperor'?" Dongfang Ziyan said lightly.

But as soon as Dongfang Ziyan's words were finished, Saron and the junior apprentice, who were resting on the sofa, laughed, as if they were laughing at Dongfang Ziyan's ignorance, and the old shopkeeper was also pursing his lips and laughing, and Dongfang Ziyan looked inexplicable.

"I said, Wang Fushun, the third emperor we are talking about in our industry is that Dongfang Ziyan......" The big Han Salon, who was sitting on the sofa, responded.

"That's the case...... Dongfang Ziyan said lightly, and then lowered his head, "You are talking about Dongfang Ziyan in the past." ”

The old shopkeeper was stunned for a moment, then touched his gray beard and said, "Yes, it was Dongfang Ziyan in the past, the three emperors we talked about in our industry are all tragic heroes, Ji Yue was killed by the Black Stone Demon Clan at a young age, and Frey was also killed by the Black Stone Demon Clan, plus Dongfang Ziyan, although he did not die, he has been out of the orbit of the peak of this world's power, and he is nowhere to be found, it is a pity......

"Tragedy...... Hero ......" Dongfang Ziyan got down from the stool, a little depressed, and muttered to himself.

"Are you alright, guest?" The junior apprentice saw that Dongfang Ziyan seemed to be a little wrong, and hurriedly asked.

"Shopkeeper." Dongfang Ziyan walked to the counter and said softly.

"What do you command?" The old shopkeeper asked.

"If I sell you the blueprints and process for making the black box cannon, how much can I buy?" Dongfang Ziyan turned around and asked.

As soon as Dongfang Ziyan's words were finished, the other three people in the workshop were suddenly stunned, especially the old shopkeeper, he held on to the high stool, and his eyes widened, and he couldn't speak for a while, only the exhaust fan turned to make a swishing sound.

Looking at Dongfang Ziyan, Dahan Saroon's eyes widened, he looked at Dongfang Ziyan incredulously, and the junior apprentice was even more stunned, he looked at this young man who was dressed simply and did not look good, and involuntarily walked to the cabinet and began to rummage through something.

"Your name is Wang Fushun at all......" Salon's voice trembled a little.

But Dongfang Ziyan didn't answer him this question at all, but walked to the old shopkeeper's workbench, picked up an engineering drawing, and a pencil, sat down and began to draw, he was drawing a sample drawing of the black box cannon, and drew the general structure of a square box with a few simple strokes, the old shopkeeper and Saron both leaned over, Dongfang Ziyan said while drawing the drawings, "Shopkeeper, I'll draw the sample construction drawings of the black box cannon for you in a while, and then tell you what materials to use, you go to assemble according to it, It doesn't take half a day to assemble it......"

The old shopkeeper and his buddy Saura in the alchemy machinery workshop were still dumbfounded, the old shopkeeper didn't say anything, just nodded mechanically, and the junior apprentice was still rummaging for something.

Sure enough, without using a cup of tea, Dongfang Ziyan finished drawing the sample drawings with precise structures, without the help of any measuring tools, nor did he observe the prototype of the black box cannon on the shelf, which was completely drawn by memory, and the old shopkeeper took the sample drawings and looked at them carefully, and he was shocked, because he didn't dare to say that this was fake, because such a precise mechanical sample drawing, if someone else could not draw it except for the manufacturer, because the precision structure of each mechanical product is different.

"Shopkeeper, I gave you the drawings, and you don't have to give me money, just let me pick a few things from you, how about it?"

The old shopkeeper looked at him stunned, nodded and said, as if he hadn't woken up from his dream, "Take whatever you want." ”

"Then you're welcome...... Dongfang Ziyan began to look around in the workshop after speaking, and it didn't take long to find a few good alchemy weapons and mechanical products, and then said goodbye to the shopkeepers.

After Dongfang Ziyan left, the junior apprentice took out a yellowed wanted warrant from the cabinet, and then said in a trembling voice, "Master...... The man just now...... It's Dongfang Ziyan......"

I saw that the wanted warrant should have been stored for many years, and the yellowed paper was painted with the portrait of Dongfang Ziyan when he was young, and the seal of the Senate was engraved underneath.
