Tang Fei and the others had arrived in the 'Heavenly City' three days ago and lived in the 'Yuelai Inn' in the northern city.

Tang Tianao was afraid that Tang Fei would leave the Tang family and suffer hardship, so he put 100,000 silver tickets in his Xuanqi ring, which was definitely enough for him to squander for a while.

After being settled, Tang Fei visited iron shops and pharmacies everywhere, collecting all kinds of rare metals and materials, and he really found a thousand-year-old diamond crystal, 30,000 taels of silver to buy a piece the size of a baby's fist, and he thought that he had hit the big luck and picked up the treasure.

After being introduced, Tang Fei learned that in this northern city, there was a master-level blacksmith who had created a saint-level mysterious weapon, and his popularity was well-known throughout the continent.

Tang Feisan has already figured it out, "There are many stunts in the Tang Sect, so it is better to give up one and take two, and no longer entangled in internal strength." At present, it seems that if you want to protect yourself, you must first make a few high-level machine bracket concealed devices, the advantage of machine bracket concealed devices is that you do not have to use internal force to release, but there are several major difficulties, one of them, the components of the machine bracket concealed device are very complex, the required materials are very varied, and the important parts are made of good steel. Second, for a person with a very high heart like Tang Fei, he doesn't disdain to use low-level secret weapons at all, and if he wants to do it, at least he must make a number that can be hung on the 'Secret Weapon Baijie'. In this way, the requirements for materials are raised by a notch again. Third, it is necessary to have a strong assembly concept and technique, and the assembly of each small component determines the grade after the formation of the hidden weapon, such as the same crossbow, the finer the workmanship, the higher the accuracy.

The largest iron shop in Beicheng 'Zhujia Iron Shop', the shopkeeper is named Zhu Bufan, strong as an ox, extremely powerful, a hammer can smash an inch thick iron into iron pieces, and only by virtue of the power of **. This is not the key, although this person is burly, five big and three thick, but he is ingenious, the iron-making technique is extremely exquisite, the handling is meticulous, the technique is skillful, with a body of strength, as long as you can draw, he can play, even Tang Fei, a well-informed person, is also shocked.

Tang Fei stared carefully at this blacksmith who was sweating profusely and shirtless in shorts, only to see that when he raised the hammer, he seemed to be extremely violent, the green muscles were angry, and the muscles on his arms also shook violently, but in fact, it was the realm of lifting weights like light, the iron hammer, a solid steel hammer the size of a human head, at least about 300 catties, but this sledgehammer was like a toy in his hand. Even the ground trembled when the hammer fell, and the pork spread on the bamboo chair behind him was even more turbulent, and the people watching were dazzled.

Tang Fei saluted respectfully and said softly, "Excuse me, is it Master Zhu Bufan?"

The strong man glanced back, did not stop, and replied with a dry thunder, "What kind of weapon?"

Tang Fei smiled happily, shook his right hand, and threw out a five-tael gold ingot, which was being thrown under the hammer, as long as the hammer head went down, the gold ingot would be smashed into gold pieces, and the strong man was immediately anxious when he saw it, and the hammer in his hand floated, and flew out, and with a bang, it smashed into the wall of the opposite house, and immediately attracted a burst of chickens and dogs.

"I'm a good one. The strong man's eyes flashed greedily, he picked up the gold ingot and stuffed it into his trouser pocket, turned his head and smiled, "I am Zhu Bufan, the guest officer is really generous, what kind of weapon do you want to fight?"

Tang Fei said, "I see that you have great strength, and it is easy to build weapons, but you can't create what I need..."

When Zhu Bufan heard this, he was immediately anxious and annoyed, and said, "Uh~ The rich young master is amazing, and he actually used these five taels of gold ingots to play with the uncle?

Tang Fei didn't take it, he single-handedly took everything, knocked the gold nugget aside, didn't care, and said, "Master Zhu, don't misunderstand, I will never play again, but the things I want to build are very exquisite, I'm afraid that if you can't play it, Master, it will ruin your reputation...".

When Zhu Bufan heard this, he was even more annoyed, and said, "Hmph~ Don't say that it's just a delicate thing, what iron tools, mysterious weapons, even holy weapons I have beaten." ”

Tang Fei saw that his surname was anxious, and he couldn't bear to make any more teases, so he took out a stack of drawings from the placket of his clothes and handed them to Zhu Bufan.

Zhu Bufan first glanced at Tang Fei with disdain, and then looked down, but with this glance, he could no longer take his eyes off the drawings.

The twenty-five drawings drawn by Tang Fei are exactly two of the three [***] hidden weapons on the Tang Gate's 'Hidden Weapon Baijie', the assembly parts of the 'Flying Claw' and the 'Arrow in the Sleeve', but they were deleted and reduced by Tang Fei, leaving only a small part.

It wasn't until a cup of tea had passed that Zhu Bufan finally read the drawings carefully. opened his mouth and said, "Childe, who gave you this picture?"

Tang Fei said, "I painted it myself..."

Zhu Bufan was surprised, he didn't believe it, he just asked again, it was obviously not appropriate, and then he sorted out his thoughts and said, "Although the first 23 are a little difficult, but I can play them, and the 24th one I can do with some good steel for three days, okay, I took this business, 500 taels of silver, a fixed price, a success, not a person..."

Tang Fei smiled, withdrew the drawings with one hand, shook his head and said, "I'm sorry, I don't want too many people to build this thing, only if all of them can build 25 drawings, I'll look for him..."

When Zhu Bufan heard this, he was immediately anxious, and hurriedly said, "The 25th piece should make this steel the thickness of a hair, and it should be as sharp as a knife, soft as hair, tough as a bamboo, steel like crystal, and it must be folded at will. ”

Tang Fei didn't reply, just took out the thousand-year-old diamond crystal from the ring and handed it over.

Tang Fei thought that this Zhu Bufan would be surprised, such a treasure is not something that money can measure for a blacksmith at all, just like a cat seeing a fishy one, a pervert seeing a beautiful woman, his eyes will definitely glow, he will be hungry and thirsty, maybe he will go up and add a mouthful.

But this Zhu Bufan was only a little surprised, and then he calmed down and said, "Even if there are materials, this kind of process is really difficult, especially the one 'tough as bamboo' is the most difficult, you must directly blast the hammer to remove impurities, not half quenching, let alone half of the Xuan force, in order to maintain toughness." This requires extremely strong ** explosive power, and my strength is probably not enough. ”

Tang Fei said, "Hehe, then I'm sorry" Then he turned around and left.

Zhu Bufan hurriedly stopped, "Wait...... I can't build it, but it doesn't mean that I can't build it. ”

After that, he walked to the pile of fat behind him, kicked it up, and only heard a 'tom', and then, the white fat snorted and shook, and Tang Fei was dazzled for a while, and then, the fat ball actually stood up, and Tang Fei took a step back in fright, thinking that he had seen a ghost. I really didn't expect that this piece of fat pork that Tang Fei had always thought was slaughtered by the head turned out to be a person.

"Ah, Dad, it's time to eat?..." A deep and honest voice, listening to this voice is just a child, it should be about the same age as Tang Fei.

He is about 1.5 meters tall and about 1.5 meters wide, with a shiny face, a face as round as a watermelon, extremely small eyes, and a fat face wrapped in meat, which can only reveal a gap. Shirtless, wearing only a pair of shorts, with a big belly hanging down to the knees, extremely unusual, in fact, he doesn't have to wear those shorts at all, this flesh-colored hakama can cover his shame.

Zhu Bufan knocked on the door of his head with a shudder, and said angrily, "Eat, eat, Lao Tzu has told you to eat the field, you still eat, I..."

In this scene, Tang Fei could see it clearly, Tang Fei's internal power and Xuan power were not allowed to be used, but it didn't mean that he had lost everything, and the purple pupil still existed. The strong man's angry kick just now, the strength attached, not to mention a person, even an inch of steel plate can definitely kick a hole, and the moment the foot and the ass are in contact, there is obviously a faint white Xuanli fluctuation, which is just fleeting, and ordinary people can't see it at all. Tang Fei was secretly surprised, in this capital, it was really Crouching Tiger, Hidden Dragon.
