The patrol leader did not go into the other rooms of the laboratory house to look for the blade. He found what he needed at the door of the house. That's exactly what was in the hemp bag at the door of the laboratory.

Inside the hemp bag was a large bundle of mid-length swords. The tips of their swords are wrapped in coarse cloth, and the position of the handles is held in place with thick ropes. As the patrol leader untied it at Mr. Pi's motion, the blade was laid flat at the entrance to the laboratory. It was neatly arranged in three columns. There are more than 100 blades, and the array is spectacular.

"When we handed it over to the old gentleman, we asked him to use talcum powder and wedge stone for a certain amount of polishing. As if he felt that he was too dependent on the old gentleman, the patrol captain said with a blushing face: "However, this matter is indeed our misconsideration. Although the old gentleman does grinding and polishing work on weekdays. But sending so many metal weapons at once is also a very laborious and troublesome matter for the old gentleman. ”

When the patrol leader handed over the weapon to the old man, he only thought that no one in Songrong Village knew such a craft except for the old man from the laboratory. Others, even if they can, are not fully competent. Coupled with the lack of time, the use is urgent. Naturally, he immediately chose the old gentleman of the laboratory who had contacts on weekdays.

The old man's ability is recognized by all the team members of Songrong Village. In addition, the attitude is very enthusiastic, which makes people like to communicate with him.

"What is the strength base of the cultivators who use these blades?" Mr. Pi carefully observed the sword blades on the ground. However, he did not ask what tools were needed, but asked the patrol leader about their needs.

"Hmm...... Most of these blades are made for our own patrol members. They are generally at the second-order level. "The patrol leader made it very clear who was going to use it. However, the patrol captain did not know the meaning of Mr. Pi's inquiry. What else do you need to pay attention to in the use of this sword blade? Isn't it the end of the matter if you directly do the best you can do with the blade?

"In that case, can you accept that I will carve the drainage pattern on the surface of the knife?" Mr. Pi continued to ask.

When Mr. Pi said this, his expression didn't change much, but the patrol captain on the side looked shocked, as if he was frightened, and he hurriedly asked again: "Senior, do you really plan to engrave the formation pattern on the knife surface? That's quite a difficult technique! Our team members don't need such powerful weapons, Mr. Pi, you'd better be simpler!"

The patrol leader politely refused. He didn't tell what was in his heart. That's not wanting to lose face for Mr. Pi.

The reason for refusing to carve the intricate formations is because they are in Songrong Village. The supply and demand side of the crystal is also relatively tight, and once the formation pattern is engraved, the crystal is definitely not enough!

Although Songrong Village is located on the edge of the Youtan Forest, you can go to collect spirit crystals or magic crystals or something. But the patrol members have to guard their posts, and that's why they usually come into contact with Warcraft only a few times a month, which is not much. As Mr. Pi said in his words, once the formation pattern is added to this blade, although the weapon will be strengthened a lot, the cost will also increase several times.

When the time comes, even the subsidies will be used up.

Moreover, the formation pattern has a certain amount of damage to the blade, which will make the blade more fragile and easy to break. Otherwise, the patrol captain will not only let the old gentleman polish and sharpen.

The patrol leader's doubts were redundant, and Mr. Pi saw through the uneasiness hidden in his heart, and said calmly: "The formation I want to engrave this time does not need crystals. It's just a formation that channels attribute power. ”

"This ...... Let me think about it. When the patrol leader heard this, he thought about what he meant. Most of the formations need the support of crystals to be able to operate stably and provide great assistance. What does Mr. Koppi mean by not needing crystals? Could it be that the blade itself is used instead of crystals as inputs? But in this case, will it be effective?

In order to confirm what he thought, the patrol leader was not in a hurry to confront him, but looked up at Mr. Pi and asked, "Senior, is the input attribute power provided by the user?"

Mr. Pi nodded slightly in affirmation.

When the patrol saw Mr. Pi's expression, he immediately asked: "But just using our own attribute power, not using the assistance of external forces, in fact, in the final analysis, the sum is the storage of those attribute powers, and it can't be strengthened much, right?" When they use the blade, they usually output the spiritual power and pour it into the blade in their hand. This formation is engraved, in fact, it is the meaning of guiding attribute power, and the total amount of input will not change from this! Since the attribute power is the same, how can it strengthen the strength of the sword blade?

"Yes. It really doesn't strengthen much, and it will even cause some damage to the blade, causing its durability to decrease. In addition, the formation pattern is engraved, which will also lead to the re-grinding and other processes. Mr. Pi did not explain this, but readily admitted it.

The blade is engraved with a pattern, and if the pattern is accidentally worn out during the grinding process, the pattern will also become invalid. At the same time, the engraving of the formation pattern is, in a sense, the thickness of the blade thinner, more brittle, and the texture becomes more uneven, which also shows that the use of the formation pattern after the engraving is reduced for a long time.

Mr. Pi's words made the patrol captain hesitate. He was beginning to wonder about the contents of the letter. The old gentleman asked him to ask the middle-aged man in front of him to help complete the strengthening of the sword blade. But no matter how you look at it, it doesn't seem to be going well! Whether it's the strengthening of the sword blade, or the seniors who say those disapproving words, as if they are refusing to help......

But it's a wasted trip and so much time?

Seeing the patrol captain's tangled expression, Mr. Pi took the initiative to speak: "The captain might as well hand over a sword blade to me to deal with first, and after completing it, I feel that the effect is enough, and then let me dispose of all the blades." How's that going?"

The letter said that the patrol captain himself should maintain enough respect for this Mr. Pi. Simply strengthening a sword blade first, a bit of a trial meaning. If the patrol captain said this to his face, it seemed that he was not sure of the ability of his senior, and he maintained a strong suspicion of him, and even made this request unabashedly.

Of course, although the request was made by the seniors themselves, it also showed that their hesitant expressions had already been seen. But it's about the use of the patrolmen, and the materials and resources are very limited, and they can't be deterred by their own momentary frustration.

Besides, when the seniors in front of him said this, they had already stepped down the ladder for him, and it would be quite unsafe to refute anything, or put forward any superfluous opinions and conditions. After all, it was he asking for it, not someone else asking for it. Therefore, the patrol captain bowed deeply and said to Mr. Pi, "Then I will bother you!"

"Okay, let's get started now. I've got some classes to take later. Look at this little guy, he's getting impatient to wait. When Mr. Pi heard the reply, he smiled flatly and said to the patrol captain. The girl was rubbing her fingers at the edge of the sword, looking curious and questioning. She was clearly not going to stay in the lab and wait for them to finish the matter.

"If you need anything, please ask your seniors to do so. The patrol leader nodded and said respectfully to Mr. Pi.

Mr. Pi didn't say anything more, but tapped the inside of the laboratory with his hand. The patrol leader who reacted had just picked up a sword blade on the ground when Mr. Pi had already taken out a small bag of tools from the inner room of the laboratory.

The tool bag is not large, only the size of half a desk.

These items look like they should be a simplified version of the Array Table. However, this removes a lot of the simplified versions that are not often used. The contents were also very lightweight, with only three pieces in total. A high-end looking dark blue shell pattern pen, a transparent folding ruler, and a black folding board.

Mr. Pi also brought out a table in the laboratory. He was on the gravel floor, trying to be smooth. The folding board was then opened and laid out on the table. The folding board is not a simple wooden board, there are some hidden hooks behind it, and Mr. Pi simply flicked it a few times, and then firmly buckled around the table, no longer moving the slightest.

After that, he placed the blade on the black board and fixed it again. to prevent random movement during engraving......

Finally, Mr. Pi picked up the formation pen and walked up on the blade of the sword. But he didn't immediately carve the pattern of the formation, as if he was thinking about the way and the way of the pattern.

Mr. Pi had a little more preparations, but the patrol leader stood beside Mr. Pi in a dignified manner, waiting for Mr. Pi to carve the blade and hand it to him. In the letter, Mr. Pi in front of him was called a warlock with a strong formation pattern technique by the old gentleman, and he didn't know what the effect of this sword blade would be after it was carved.

The patrol captain needed these blades so badly that he could just pick them up and leave. But I don't dare to be impatient at the moment. The formation technique is not a pile of mud, how can you open your mouth like a predecessor asking for the finished product of the sword blade?

Fortunately, Mr. Pi's thinking about carving the formation pattern did not last long. He thought of the formation pattern, and slowly landed the formation pen on the side of the blade.

It's just that the process ......of carving the pattern is not so beautiful and gorgeous. What a burst of sparks, and gorgeous dazzling attribute power. There was only a noisy cacophony of rubbing. It's much sharper and more piercing than grinding with grinding stone powder and wedge!

The patrol leader frowned slightly and looked at Mr. Pi's operation. Mr. Pi's pattern carving is very strange, and his pattern pen is not embedded with any crystals. It is simply engraved with a pattern pen. At the same time, the sound of the sharp friction of the blade made him a little worried.

The louder the sound of the formation pen engraving, the less sharp the formation pen is. It can also be explained that the level of engraving is low! Is Mr. Pi really the high-level formation warlock mentioned in the letter? How can you look at the level of operation, which is slightly poor?

However, the patrol leader had barely frowned when Mr. Pi straightened up.

"Alright. Mr. Pi said to the patrol leader next to him, "Take it and try it." ”

"So fast?" the patrol leader swallowed. Mr. Pi wouldn't be fooling him, would he? It would take such a short minute or two to carve a formation pattern? I usually look at those formation pattern masters and help them carve the formation pattern, a sword blade can be done for a few days at most, and it will take more than ten minutes to portray it!

However, since Mr. Pi has completed it, then it is better to see for yourself before deciding!

The patrol leader took the blade and first observed the lines on it. The lines on it are right-angled, no more than twenty, and most of them are engraved on the handle of the blade, not on the side of the blade. There was also a slight amount of metal powder carved out of it.

Erase the metal powder from above. The patrol leader squeezed it lightly.

The first is the feel. The weight of the blade after the engraving has not changed much, but the position of the handle seems to be a little different when pinched, and there is a relatively clear sense of concave and convex. The patrol leader looked at the position of the pattern on the handle and felt that it was not safe for the senior to engrave the pattern here, because the place would be wrapped in cloth or wood afterwards to improve the grip.

"Let's try to instill spiritual power into it. It is for this reason that the drainage pattern is engraved. Mr. Pi said blandly to the patrol leader.

The patrol leader coughed lightly twice, and his face flushed slightly. It is the best way to patronize and see how the formation pattern is engraved, and forget to test it directly with attributes.

The patrol leader fed his stat power into the blade. As soon as he entered like this, he suddenly noticed something strange! Compared with the previous method, this attribute power input was more rapid! It seemed that all the pipes in the middle were directly connected at once! The attribute power was much less!

With a swing of the sword, the tiger was mighty. The patrol leader's face couldn't help but smile with satisfaction. He really underestimated his predecessors before!

Even if the defects and engravings of the previous ones would damage the blade, the predecessors actually engraved the formation patterns on the handles and the bottom surface, which did not damage much at all! They can still polish the edge of the blade, and they don't have to worry about grinding the formation patterns!

At the same time, the input of this attribute force is much lighter, but it is not a psychological effect, but this change is really felt, which shows how amazing the formation pattern carved by Mr. Pi is!

Whether it is in battle, the speed of the added attribute power, or the protection of the blade, the reduction of the use of attribute power, it is a very huge direct increase!

Seeing that Mr. Pi was still looking at him, the patrol leader suddenly remembered his purpose, hurriedly put away the blade, immediately bowed, and said, "Senior, your formation pattern skills are very good. I still ......"

The suspicion just now made it a little difficult for the patrol leader to speak. In fact, just now he thought that his predecessors just needed not to be too strange and carve out a reluctantly acceptable formation pattern! But in the end, he gave him such a big surprise. He was really flattered!
