In the depths of Mang Mountain, Wu Xueji and Wu Hook came to a deserted place with the cast imitation Yuan Tu Sword. This is an extremely hidden canyon in the mountains, and on the cliff of the canyon, there is a very inconspicuous small cave, about two people high from the ground.

Wu Xue's father and son both had kung fu, and when they came to the entrance of the cave, they jumped lightly and entered the cave. After entering the cave, there is a copper gate in front of you, which seals the entire entrance of the cave tightly, and the owner of this cave should be an expert in mechanical arts.

Wu Xueji took out the imitation Yuan Tu Sword and plunged it into the small crack on the door.

"Come, Hook, look around. Wu Xueji gestured to Wu Hook with his eyes, Wu Hook nodded, held the handle with both hands, and slowly strained, but there was no trace of the key hole on the door turning.

The father and son glanced at each other, and Wu Xueji raised his eyes and asked Wu Hook to continue to exert himself. Wu Hook's hand exerted his strength again, increasing his strength. But the keyhole in the door still showed no signs of turning.

"Work harder!" Wu Xueji frowned and said.

Wu Gou's face began to show a trace of hideousness, and he couldn't help but gradually use internal force in his hands, and the green tendons on his head slowly erupted.

"Click!" There was a crisp sound of breaking gold, and Wu Hook's hand suddenly lightened, and he didn't stand firm for a while, he stumbled and fell back two steps. Wu Xueji's father and son glanced at each other, and they both saw the surprise in each other's eyes.

At this moment, the heavy door "clanged", shaking down a layer of ash, Wu Xueji, father and son took two steps back, and then the door opened with a "squeak".

"What's the matter? Then this kind of garbage also wants to open your Uncle Gu to do the door?" An old voice came from behind the door, and an old man with a somewhat shrunken figure walked out.

"I've seen Gu Lao!" Wu Xueji saw the person who came, and immediately bowed and saluted. Wu Gou followed and lowered his head to the ground.

"Well, come with me. The old man, who was called Gu Lao, raised his somewhat gray and cloudy eyes and glanced at Wu Xue's stepfather and son, then turned around and walked towards the cave. Wu Xueji, father and son, glanced at each other and raised their heels.

Walking inward along the entrance of the cave, there is a long Yongdao, there is a lampstand every five steps on both sides of the Yongdao, and the night pearl is inlaid on the platform, which illuminates the whole Yongdao. Wu Xueji also entered the cave for the first time, and he was quite curious, let alone Wu Hook.

Slowly, Wu Xueji discovered a situation. Walking deep from the entrance of the cave, this corridor is very narrow and long, the earliest time there was only a width of six people in parallel, Wu Xueji thought that this corridor was straight inward, equal width, but after walking for about half an hour, Wu Xueji suddenly found that there were already ten people in parallel width, and then he was surprised that the corridor was getting wider and wider.

Walking to a depth, a round table stood in front of Wu Xue's stepfather and son, and a beam of light shot from the top of the cave, just covering the round table and the round chairs around it. It was dark all around, and it was impossible to see how big the hole was or if anyone else was there. Such an environment made Wu Xue's father and son feel strangely cold.

"Sit down and talk. Gu Lao pointed to the round table, walked straight over, and sat on the chair opposite the corridor. Wu Xueji and the two arched their hands, and found the two chairs closest to the corridor to sit down, which happened to face Gu Lao, and it was also the farthest place from Gu Lao.

It's not that Wu Xue and the two are estranged from Gu Lao, it's just that in this environment, only the chair on this side of the corridor has light behind it, and the rest of the chairs are dark behind it, and I don't know if anyone or something is staring, which makes people feel quite uneasy.

"Show me the broken sword. Gu Lao said lightly, without any change in expression on his face. Wu Xue said "yes", then took the broken sword in two from Wu Hook's hand and handed it to Gu Lao. Gu Lao picked up the sword, put the two severed swords together, looked at it carefully with the beam, gently stroked the sword body with his fingers from the hilt of the sword, carefully stroked the texture boy, and then turned around and touched the sword body on the other side, and then nodded.

"The lines on the sword body should be correct, consistent with the Yuan Tu sword handed down from the ancestors, and naturally consistent with the lock cylinder. But the sword is not hard enough to pry the lock cylinder. My lock cylinder is just an imitation, the real lock cylinder, I'm afraid it will be heavier, your sword can't even open my lock cylinder, let alone the real lock cylinder. Gu Lao pushed the sword back and said in a cold voice.

"This ...... Gu Lao, this is what I spent a lot of money to find the sword casting master, Master Xu Tao Xu of Yunmengze! Gu Lao...... How do you say to find a more powerful swordsmith?" Wu Xueji smiled a little helplessly.

"The man who built this good sword is really good at craftsmanship. But it's a pity that the materials are not good, if you use mortal iron to fight weapons, even if the strength of the swordsmith is profound, the achievements of the sword are limited. Gu Lao didn't look at Wu Xue's stepfather and son, and said to himself.

"That'...... Then let's go fight again?" Wu Xueji asked a little dumbfounded.

"No need, this sword is indeed no problem in the texture, but you have all overlooked one thing, that is, have you carefully considered the depth of the texture of the sword body?"

"This ...... The previous steward said that as soon as he got the real sword, he measured the depth of the texture of the sword body with his hands. Wu Xueji replied with some astonishment. I didn't think that Gu Lao shook his head and said that it was not right.

"Your steward only touched the depth of the sword body texture at the beginning, but he didn't touch all of them, otherwise he wouldn't have made such a mistake. Gu Lao pointed to a few places, Wu Xueji looked at Wu Hook, these are a few places on the lines, and Wu Xueji was very sharp-eyed to find that the points pointed to were connected very similar to the position of the Big Dipper.

"What is this?" Wu Xueji asked with some strangeness.

"The Big Dipper Chart, on the artwork given to me by my master, there are seven points marked, and the depth is deeper than that in other places, which constitutes the Big Dipper Chart. Your imitation, the texture and texture depth are right, but it lacks the depth of the Big Dipper. Gu Lao pointed to the broken sword and said.

"Then Gu Lao, do you know the depth of this Big Dipper?" Wu Xueji hurriedly asked.

"Hmph, if I knew, would I still need you to check it?" Gu Lao snorted coldly, this Wu Xueji's ability is not bad, but after all, he lacks knowledge in smelting and sword casting, and it is really a little difficult for him to let him do things perfectly.

"Then, in Gu Lao's opinion, how should this matter be resolved?" Wu Xueji asked.

"Get the real sword, before the others react. Gu Lao raised his eyes and glanced at Wu Xueji, and continued to look down at the sword. When Wu Xue heard this, she looked at Wu Hook, and then smiled bitterly. If this sword bearer is a nobody, it would be fine, but the Yuan Tu Sword is the treasure of the Shaolin Temple, how dare Wu Xueji make a mistake in the Shaolin Temple?

Thinking of this, Wu Xueji couldn't help but sigh......
