After sending off the army, Zhang Wushu came to the stable, rode Xiaohong and went to Qiuming Mountain, because there was Wang Ba first, so Zhang Wuxian quickly found the way. After arriving at the place, Zhang Wuxian turned over and dismounted, and like Wang Ba, he first knocked three times on the wooden door: "Senior, junior Zhang Wuxian came to visit, please meet the previous one, the younger generation has something to ask for." ”

"I just retreated from a general in the face of difficulties, and now there is a scholar with a crepe, I am on the famous mountain in autumn, but I have never been so lively. Young man, I see that you know some politeness, so I sincerely advise you to leave as soon as possible, otherwise you will pay a great price. If the old man says that if he does not see the world, he will not see the world. ”

Zhang Wuxian nodded, and then smiled: "Thank you seniors for your kindness, but the juniors don't know, what is the price? The juniors also want to try it, and since the juniors are here today, they must see the seniors." ”

"Okay! I'm still a persistent person, in that case, I'll leave the words here, as long as you can get past these organs of the old man, the old man will allow you to come in and meet the old man. However, the old man can tell you for sure that you will definitely not be able to get through this mechanism, and it is very likely that you will take your life, so young people had better think clearly. ”

Zhang Wuxian smiled faintly: "The juniors think very clearly, and they will definitely see the seniors today." At the same time, Zhang Wuxian had silently opened up the meridians of his body with his golden branch hand, and his breath circulated to all parts of his body, so that he could flexibly use his internal force at any time. Moreover, at this time, Zhang Wuxian had already paid attention to it.

Walking and walking, Zhang Wuxian suddenly had a thrill in his heart, and then hurriedly jumped into the air, but a large piece of iron thorns grew out of the ground above the ground, Zhang Wushu saw this, sneered, and then rushed down, and at the same time urged Sancheng's palm wind, and directly hit the iron thorns on the ground back. After falling to the ground, I only heard the old man say in a sloppy manner: "Good boy, you have some skills, better than that reckless general!

Zhang Wuxian didn't pay attention to the old man, but silently walked forward, when he arrived at the door, Zhang Wuxian stretched out his hand to push the door, at this time, Zhang Wuxian's center of gravity suddenly became weightless, and then he felt his own 180 degrees rotated, and when Zhang Wuxian reacted, he found that he had been netted by the iron net, Zhang Wuxian transported the internal force of the whole body to his hands, and wanted to tear the iron net off, but he didn't know that no matter how hard Zhang Wuxian tried, the iron net was not deformed in the slightest.

Besides, the harder Zhang Wuxian worked, the tighter the iron net would bind. Immediately, I saw that the iron net slowly moved towards the outside of the fence, and when it reached the top of the wooden door, the iron net opened and released Zhang Wuxian, but Zhang Wuxian was not like Wang Ba, who was thrown to the ground alive, but quickly turned around and fell to the ground safely.

Zhang Wuxian smiled faintly: "It's kind of interesting." Immediately, he jumped up again, only to see Zhang Wushu just jumped up, and there were countless arrows flying towards Zhang Wushu in mid-air.

After the palm wind collided with those arrows, the arrows suddenly fell to the ground, and then, Zhang Wushu also swooped towards the hut, at this time, the sky gradually darkened, and when he looked up, it was a net of heaven and earth pressing towards Zhang Wuxian. Seeing this, Zhang Wushu secretly screamed in his heart, when he pulled out the male and female sword on his waist and slashed directly into the air, how sharp is the male and female sword?

Then, with a bang, Zhang Wushu put the male and female swords back again. Then, Zhang Wuxian walked towards the thatched hut again, and suddenly, at this time, Zhang Wuxian's feet slipped and he immediately fell to the ground. After Zhang Wuxian reacted, he found that he had been hit by the trap.

Zhang Wuxian looked around, but it was pitch black, and he immediately scolded in his heart: "Damn, I knew that Lao Tzu was okay and floated in the air, and he didn't fall to the ground." Then, Zhang Wuxian directly urged fifty percent of his strength and hit the ground above, although the palm wind touched the ground, but the ground was also a bulge, but it soon returned to normal.

Zhang Wushu knew that this was the old man's use of a very malleable substance to seal the ground, and the principle used was to overcome rigidity with softness, so even if Zhang Wushu used ten percent of his strength, at most it would be a higher bulge, but the ground would indeed not change in the slightest.

Thinking of this, Zhang Wushu gave up the method of using the palm wind to open the exit of the ground, and touched the male and female swords on his waist again. Clinker, before Zhang Wuxian pulled out the male and female swords, the old man's voice suddenly sounded beside Zhang Wuxian: "Young man, don't you want to see me, what do you have to say." ”

Zhang Wuxian frowned: "Senior, you live in this place?"

The senior nodded: "What's the fuss, it's not like you haven't seen an old thatched hut." ”

Zhang Wuxian frowned: "Now, the junior is in the thatched hut?" But the junior remembers that the junior fell downward, how could he appear in the senior's thatched hut?"

The old man smiled faintly: "The old man has been doing a workshop for more than 80 years, if he doesn't even know this, then the old man will live so much in vain, let's talk about it, risk his life to find the old man, what is the matter?"

Zhang Wuxian nodded: "Senior, I don't know if I can light the oil lamp?" Now, the junior doesn't even know where the seniors are" Zhang Wuxian groped around and said.

"It's okay!" After that, the oil lamp in the room was lit up, and Zhang Wuxian covered his eyes, and it took a while to get used to it. I saw that there were four tables in front of me, and each table was full of countless pieces of wood, but I saw that the old man was wearing a head full of white hair, sitting on the innermost table, and he didn't know what he was making in his hands.

Seeing this, Zhang Wuxian hurriedly smiled at the old man and arched his fist: "Junior Zhang Wuxian, I have seen my seniors." ”

"Okay, these mundane etiquette are of no use to me, and besides, you are an emperor, what is the matter with saluting the old man? The old man was still tinkering with the things in his hand, and he hadn't looked at Zhang Wuxian since he came in.

Zhang Wuxian glanced at the things on the old man's table, and found that the old man had been repeating a craft work, and it seemed that he was confused by which link. Zhang Wuxian knew that since it had reached this point, of course, there was no need to beat around the corner, so he paused and said: "Senior, the junior came here this time to ask for an important matter, this matter is related to the demise of my new dynasty, and I also ask the seniors to come to the rescue." ”

The old man frowned slightly, but there was no reply. Zhang Wushu glanced at the old man, paused and continued: "Previously, Zhang had delivered a drawing of the Vajra Thunderbolt to the Yeyang Workshop, and it took nearly half a month of hard work to get one out for me. Now, the war situation is urgent, and it must be rushed out tonight, otherwise it will delay the military plane, and it is very likely that it will be destroyed by the girder. ”

After hearing this, the old man just nodded slightly: "So, you found the old man? Presumably, even the address of the old man was told to you by the boss of the Yeyang Workshop, right? This little cub seems to don't want to get mixed up." ”

Zhang Wuxian smiled awkwardly, thinking that this old man didn't say anything about helping himself, and he was suddenly a little helpless. Unconsciously, Zhang Wuxian stared at some objects in the old man's hand and became distracted. I saw that the old man was holding a wooden board in his left hand and another wooden board in his right hand, seeing that the old man repeatedly changed the angle, he wanted to swap the two wooden boards together, but the screws did not appear in this era, Zhang Wuxian smiled slightly, and suddenly had a countermeasure in his heart.

Zhang Wuxian pointed to the two planks in the old man's hand, and said, "The seniors want to glue these two planks together?" At first, the old man didn't pay attention to Zhang Wuxian, and then nodded and said: "Yes, but as for how this sticks, you still need to think about it, if you use paste, not to mention that its viscosity is reversible, and it can't be used in industrial products, so the old man can't help but have a headache." ”

Seeing this, Zhang Wuxian smiled lightly: "Senior, junior has a way to glue these two planks together completely without using paste, whether they are parallel or perpendicular, they are different sides. ”

After hearing this, the old man first showed a look of surprise, and then instantly dimmed: "You are an emperor, not a craftsman, how can you know this craft." Besides, do you know if you're lying to you?"

The old man smiled calmly, and then took a small wooden block and a small knife from another table, and then, Zhang Wushu used a knife to cut the small wooden block into the shape of a screw, and then Zhang Wuxian took a small wooden board again, and sat on a base used to fix the screws, and then, Zhang Wuxian took the two wooden boards in front of the old man, and gently made a small opening between the two wooden boards with a knife, and then used the screws made of wooden blocks to penetrate it.

After passing through, Zhang Wuxian picked up the base of the fixing screw, slowly screwed it up, and after screwing it, Zhang Wuxian moved left and right, making sure that it was not loosened before putting it back in front of the old man again.

From beginning to end, the old man kept looking at Zhang Wuxian dumbfounded, and after Zhang Wuxian finished and put it back in front of the old man, the old man hurriedly took it from the table in his hand, and looked at it vigorously like a pearl in his palm, and only after a long time did he say: "Wonderful, wonderful! The thread of this small wooden block is a long inclined plane, but the angle is very small. It can be assumed that when you twist the thread, it is equivalent to pushing a block on an inclined plane. ”

Zhang Wuxian smiled and nodded, expressing his agreement with what the old man said: "Senior, in this case, can you ask the seniors for help? After the matter is done, Zhang and the senior will discuss this screw. ”

"The name of this thing is a screw?" the old man was obviously a little surprised when he heard the name for the first time.

Zhang Wuxian nodded with a smile: "That's what everyone we call there." ”
