The old man frowned and said, "young man, pay attention to your words! This is the mineral deposit of the mountain country. If you let the temple hear your words, the consequences will be..."

"OK, look at the arrangement." Lu Xing compromised.

"I'm not familiar with your weapon refining method, so I still need to trouble you." Gu Laowu ordered, "call people from all major sects tomorrow. You're responsible for teaching them the weapon refining techniques. Refine all parts first."

Lu Xing did not refute, because he knew that refining was often the simplest of such a huge project. The difficulty is the final assembly and operation. Unfortunately, the knowledge reserve of the people here is too weak to complete such a precise operation. Therefore, the most important link should fall on the head of a lonely old man.

The leaders of the major sects were also dispersed. The mission of mending the sky is about to officially begin, and these leaders do not need to follow in the four cities. The temple ordered them to return to all sects for standby. It was enough to leave a messenger in the Sifang city.

Beside the temple's thigh, Mo Chengfeng also temporarily took Lu Xing helpless. But when I left, I repeatedly stressed that a unique craft must not be cheap to others.

The sky mending messenger set up an array hundreds of miles outside the Sifang city as a temporary weapon refining place for Gu Laowu and Lu Xing. After all, there are ordinary people in Sifang city. The movement of refining tools is not small. I'm afraid it will disturb their normal life.

A steady stream of materials have been delivered to Sifang City, and the people of the weapon refining groups of various sects are also moving towards Sifang city. Everything is ready except the east wind.

They confirmed the contents of the Tianshi atlas again and again for fear of making mistakes in any place. As a result, over the past ten days, Gu Laowu finally came to a conclusion: "the principle of this thing is similar to that of the storage bag. However, the complexity of Tianbu stone is much higher than that of the storage bag. If I hadn't read the atlas, I can't believe I could refine such a huge space."

Lu Xing said, "you mean space compression technology? Can you refine storage bags?"

"You'd better be cautious in your words and deeds. I think you look like an expert when you don't speak. Once you open your mouth, you look like an idiot. The storage bag doesn't grow out of the earth, let alone fall from the sky. As the only refining master, you can't even know the most basic storage bag?"

"I won't." Lu Xing spread out his hand, "why don't you teach me?"

"That's OK. I'm idle anyway."

With more than enough materials, Gu Laowu taught Lu Xing to refine storage bags on the spot. The first step is not much different from Lu Xing's usual refining, but Lu Xing is used to refining in batches, while Gu Lao Wu is formed in one shot.

The key is that in the last step, when the storage bag is about to take shape, Gu Laowu suddenly opens his eyes, gathers his aura on the fingertips of his hands, and quickly draws a pile of arrays at the key parts of the storage bag. Between the calcium carbide sparks, Gu Laowu has drawn hundreds of arrays. It's really thanks to his hand speed. He can't be alone at an age without a wife and children.

Lu Xing asked, "your last step is to draw the array? Can you spread it on the paper and show me?"

Gu Laowu didn't hide anything. He found a few pieces of paper and drew the array one by one. He has already mastered these arrays. After watching for a long time, Lu Xing grabbed the storage bag and tore it open.

A storage bag that had just been baked was disassembled by Lu Xing. Lu Xing found that the array was engraved on each key part of the storage bag. Whenever the spiritual power flows from the storage bag, it is bound to pass through these places.

I always feel familiar.

Thinking about it, Lu Xing took out Fang Tianshi again, drew gourds and prepared to dissect on the spot. Scared, the old man shouted, "be merciful! I only have one piece of this thing. Don't dismantle it for me! This is an array. Take it yourself."

Lu Xing said, "stingy! It's not that you can't refine it."

Gu Laowu said, "do you think this is Chinese cabbage? It took me ten years to find the materials of Fang Tianshi."

"You can use the materials here. I'm afraid you can't refine them?"

"If you want to refine yourself, I don't have the time."

Gu Laowu not only took out the array of calcite, but also told Lu Xing the refining method. But Lu Xing's level is limited. He is a technical talent, not an engineering contractor.

After seven or eight days in a row, Lu Xing was always immersed in the structure of square Tianshi.

"I understand!" Lu Xing suddenly jumped up, grabbed a handful of materials and threw them into the ground fire.

The lonely old man was startled and scolded from rubbing his confused eyes: "yell! What do you understand?"

Lu Xing said excitedly, "array! What's special is the circuit diagram! All the problems about energy conversion are solved easily. Gu Laowu, you are really a talent! How did you come up with these arrays?"

Gu Laowu said, "I don't understand what you're talking about. I created these arrays. What's the problem?"

"You're really a genius! How do you know the formula of the great unification position?"

"What is the devil's unified position? I don't understand. This is the array experience summarized by countless predecessors. Take it yourself."

Gu Laowu shook his head and threw a copy of the diagram of refining tools to Lu Xing. The content of the first half of this book is to record some tips for refining utensils. Lu Xing is naturally not interested.

The second half of this book is all about the array forged by the refining instrument. It is explained step by step from introduction to mastery, from foundation to advanced level. The above is full of comments of Gu Lao Wu. It can be seen that he is worthy of invading this way for many years.

However, Lu Xing has no time to study for the time being. He has to verify what he thinks in his heart first.

In the past, he paid attention to the structure of weapons when refining weapons. For example, the Ling gun is changed according to the structure of the fire gun, and the use efficiency is limited after all. Once separated from the original structure, the weapon is damaged.

However, Gu Lao Wu provided him with another idea, that is, through the array - circuit diagram and hook weapons, the spiritual power can be more effectively transformed into various energies.

All kinds of parts come out of the ground fire furnace, including sections, pieces and columns. The largest is the size of a palm, and the smallest is the size of a fingernail.

At a glance, Gu Laowu could see clearly that the parts the size of the fingernail were carved with the array of calcite. Each moment, positive and negative, can be engraved with two. There are more than 10000 arrays of calcite. Lu Xing is really not afraid of trouble. He has refined more than 7000 parts.

Lu Xing's hands were like an illusion, and he installed every part in full. Finally, a simple long sword appeared in Lu Xing's hands.

Gu Laowu hesitated and said, "you beat the drum for several days and nights, and then you beat out a flying sword?"

Lu Xing smiled and didn't speak. His backhand was a sword waving to Gu Lao Wu across the air. Gu Laowu couldn't touch his head. When he was wondering, he suddenly felt that there seemed to be something invisible pressing down from the top of his head. Thanks to his profound skills, I'm afraid he will be crushed into powder on the spot if he is below the break of love period.

"Fang Tianshi... Well, Fang Tianjian?"

"I like to call it gravity sword." Lu Xing loves the new weapon.

Gu Laowu said happily, "you've finally used a normal weapon. The laoshizi linggun is powerful. Unfortunately, it looks too ugly."

Lu Xing: "
