Zhang Nian and 'Olaf' waited in the study of 'Olaf' for a while, Zhang Nian finally saw the name of the 'designer''s friend light up, Zhang Nian was overjoyed in his heart, this 'designer' was finally online, which almost killed himself and 'Olaf'.

"City Lord, that brother of mine is already on his way here, I'll open a portal to pick him up." Zhang Nian said excitedly, quickly add the 'designer' to his team, and then let the 'designer' quickly take a look at the message he sent him, don't wear it when it's time to talk to 'Olaf', and then tell the 'designer' that the portal is at the resurrection point of 'Thunder City', and you can come directly to your room after entering.

After Zhang Nian explained everything to the 'designer', Zhang Nian couldn't help but get excited, I really don't know what level of secret weapon the drawing that the 'designer' took this time is, I don't know what level of secret weapon manufacturing method the 'designer' knows, if the 'designer' knows the manufacturing method of one or two tenth-order secret weapons, then wouldn't he be able to directly kill a god-level master with this tenth-order secret weapon now!

Zhang Nian and 'Olaf' waited anxiously for five minutes, and the 'designer' finally came slowly, and as soon as the 'designer' came out of the portal, he saw two big men staring at him.

"Well, what are you looking at me like this, and I don't have flowers on my face!" The 'designer' asked rather innocently.

"You're the one who owns a blueprint for a hidden weapon? I'm Olaf, the lord of the City of Blacksmiths, can you show me your hidden weapon blueprints, I'm very interested in your hidden weapon blueprints! Can you please show me. 'Olaf' said excitedly.

"Of course, this is a hidden weapon drawing I brought, this is just a relatively simple hidden weapon design drawing, and there are many such hidden weapon drawings handed down from my ancestors in my family. My dream has always been to forge these hidden weapons, but because my personal forging technology level is too low, and the forging demand for each part of these hidden weapons is too high, so I have not been successful in forging, and one of the reasons why I am looking for you is because you are the lord of the blacksmith city, and the mastery of forging technology is one of the best in the entire human race, in fact, I have long wanted to come to visit you, but because of all kinds of originals have not come, I just happened to hear that this brother of mine has a good relationship with you, So I asked him to introduce me to it. "The 'designer' was also very excited to see the lord of the city of blacksmiths.

"Okay, let me see the design drawings of your hidden weapon first, I want to see first, whether the design drawings of your hidden weapon are correct, and whether it is possible to achieve powerful lethality after forging. As for the problem of forging, I may not be able to forge a secret weapon above the tenth order, but I am still sure to forge a secret weapon of the eighth and ninth orders, you can rest assured, as long as the forging drawing of your secret weapon is true, I will definitely forge it for you. 'Olaf' swore as he looked at the drawings.

Zhang Nian has never seen the design drawings of this hidden weapon, and 'Olaf' said that the hidden weapon is so miraculous, so Zhang Nian has a great interest in the content of this hidden weapon design drawing, and he is worried about the back of 'Olaf', and 'Olaf' to watch the design drawings of this hidden weapon together.

Zhang Nian looked at it for a while, and found that the precision of this hidden weapon is really extraordinary, and the coordination relationship between the various parts in the hidden weapon needs to be very close, which also puts forward great requirements for personal forging technology.

The drawings brought by the 'designer' this time are the design drawings of a 'Sleeve Arrow', this kind of 'Sleeve Arrow' is a small hidden weapon, mainly placed in the sleeve, unexpectedly, hit with a blow, if this kind of 'Sleeve Arrow' is in real life, Zhang Nian has no doubt that this kind of 'Sleeve Arrow' can kill a very strong adult at once.

If you are within three meters of the person who launched the 'Sleeve Arrow', you are likely to be unable to dodge it with your own body speed, so that you will be plotted by others, this 'Sleeve Arrow' is really too powerful, and the reputation of the hidden weapon is really worthy of its reputation! It's just that I don't know if this 'hidden weapon' that can show off its might in real life can shine in this game, and if the design is successful in the game, what kind of hidden weapon type can it be counted as!

Zhang Nian looked at it for a while, and finally understood the manufacturing process of this 'Sleeve Arrow', although the manufacturing process of this 'Sleeve Arrow' is extremely precise, but it is very simple, as long as you are careful when forging it, there is no problem at all if you want to forge this 'Sleeve Arrow', and the design of this 'Sleeve Arrow' is very simple, almost at a glance, all the forging parts only need the word 'careful', even if it is some ordinary blacksmiths, it should be easy to forge it.

"This ...... Is your hidden weapon drawing complete? Did you take a little less when you took it? Olaf suddenly asked in confusion!

"Take less? It's impossible, I've seen this drawing many times, this is all the drawings for the manufacture of the 'Hidden Arrow', and there is no need for other drawings at all. The 'designer' said suspiciously.

"That's right, city lord, I also read the design drawings of this 'Hidden Arrow Arrow', although the parts are very precise, but as long as the blacksmith is careful enough, it is not a problem to make this 'Hidden Arrow' at all, I can forge a complete version in less than an hour according to this drawing, and I see that the design drawings of this 'Hidden Arrow' are the complete version!" Zhang Nian also asked suspiciously.

"Alas, you don't know, the design drawings of this 'Hidden Arrow' are indeed the complete version, but this drawing is missing a very important part, which is the enchanted part of this 'Hidden Arrow'."

"The part you see is just the production part of the hidden weapon of the 'Hidden Arrow', and the reason why the 'Hidden Weapon' is powerful is not only because of the precision and concealment of the 'Hidden Weapon', but also on the damage of the 'Hidden Weapon'."

"And the simple damage of the 'hidden weapon' is through the precise conversion of various mechanisms, as far as this 'hidden arrow' is concerned, the 'hidden arrow' is indeed very powerful when it is launched, but for a warrior carrying a shield, it is useless, if this 'hidden arrow' hidden weapon is successfully made, it is likely to be a fourth-order hidden weapon, a fourth-order hidden weapon can easily kill a player of about forty levels, why can this 'hidden arrow' kill a player of level forty? Is it just the power of this 'Hidden Arrow' that is launched? Impossible. It is more important to carry out various enchantments on these parts when forging the parts of these Hidden Arrows, and greatly enhance the power of this 'Hidden Arrow' through the power of these enchantments. ”

"I saw from the ancient books that the most powerful hidden weapon, on a small arrow, there will be several enchantments, curses, damage, bleeding, poisoning, and all kinds of enchantments, this 'Hidden Arrow' can really exert his power."

"But don't be discouraged, it's not easy for us to get this drawing just now, this drawing is the essence of this 'hidden weapon', the design principle of this hidden arrow, I can understand it after looking at it for a while, I haven't spoken just now, I'm still looking at this drawing, I'm just thinking, what kind of enchantment is carried out on these parts, the power of this 'hidden arrow' can reach the level of his fourth-order hidden weapon, and it can kill a player about level forty as soon as it is launched."

"This 'Hidden Arrow' secret weapon is just a fourth-order hidden weapon, and there are not many enchantments that can be used, I just studied it carefully, and I have figured out all the enchantments needed for this 'Hidden Arrow', as long as the forging is completed, and then attach the enchantment, the power of this 'Hidden Arrow' can reach the power of the fourth-order hidden weapon. Wait a minute, I'll go find a piece of paper and write down the enchantment I thought of for this 'Hidden Arrow', so that the two drawings together, this 'Hidden Arrow' is a complete version of the hidden weapon! 'Olaf' explained.

After Olaf finished speaking, he quickly found a piece of paper and began to write all the enchantments that Olaf thought of on the paper, Zhang Nian took a closer look at it next to him, and found that there were some intermediate piercing enchantments, low-level damage enchantments, and primary fragility curse enchantments.

"City Lord, why don't you enchant some powerful enchantments on this 'Hidden Arrow', why did you only write some primary and intermediate enchantments, wouldn't you enchant him with some high-level enchantments to make this 'Hidden Arrow' even more powerful?" Zhang Nian asked suspiciously.

"Alas, I asked you to read more books on enchantment, and as soon as I heard you say this, I knew that you definitely didn't read it, a good blacksmith will only forge any good equipment, and a good blacksmith is definitely a good enchanter."

"I'll tell you why this 'Hidden Arrow 'Hidden Arrow' weapon only enchants these primary and intermediate enchantments, and not some advanced final enchantments."

"The inscription itself is very powerful, we seal the power of the inscription on a piece of equipment through various methods, this process is called enchantment, and the inscription itself is divided into ultimate, advanced, intermediate, primary, and low five levels according to his power, of which the ultimate enchantment is the most powerful, and the primary enchantment is the least powerful."

"If you want to enchant an inscription to a piece of equipment, the first thing to see is how powerful the inscription this equipment can withstand, just like an ordinary cast iron equipment, he can only bear the enchanted primary inscription, and at most can only enchant an intermediate inscription, but if you forcibly enchant this equipment with a high-level inscription, it will make this equipment because it can't withstand the power of this high-level inscription, and it will directly explode, explode, and become a terrifying bomb. Therefore, the inscription I ordered for this 'Hidden Arrow' is mainly an intermediate primary inscription, and the power of the inscription of this strength is just right for this Hidden Arrow. Olaf explained.

"City Lord, then when we forge this equipment, we directly use materials with strong bearing capacity as the base, so can we enchant some powerful inscriptions, so that the power of this 'Sleeve Arrow' will also be greatly increased?" Zhang Nian asked suspiciously.

"You're right, if we use some powerful materials to make this Hidden Arrow, we can indeed enchant some powerful inscriptions on this Hidden Arrow, so that this Hidden Arrow can grow into a fifth-order, sixth-order, or even seventh-order, eighth-order, or even ninth-order hidden weapon, but the effect of this is not good."

"First of all, it's a matter of materials, if you want to build a good equipment, the materials he needs are also very good, this sleeve arrow is destined to be a large number of forged equipment because of the simple forging, so, the most suitable enchantment is still suitable for low-level enchantment of ordinary materials, the second is the problem of this sleeve arrow itself, the mechanism of this sleeve arrow itself, the design precision of internal parts, strength, etc., compared with a good hidden weapon, this is a scum, a good hidden weapon, can hit the damage of one out of ten, and this sleeve arrow can only hit three, Therefore, it is really not worth using some good materials to forge such a small output ratio of equipment, so this Hidden Arrow still needs to be forged with ordinary materials, and the simplest inscription for enchantment is the most. Olaf explained again.

"Oh, so that's the case, it seems that I really want to go back and see more about enchantment in the future, in fact, I've seen it in the past few days, but I've been looking at the drawing of the inscription, but I haven't looked at the most basic things, it seems that I need to study it well." Zhang Nian said embarrassedly when he heard what Olaf said.

"This little brother, I don't know if you still have a 'hidden weapon' drawing like this in your hand now? Can you put the blueprint of this Hidden Arrow here first, and I'll forge a finished fourth-order Hidden Arrow for you tomorrow. Olaf asked anxiously looking at the designer.

"There are actually some such hidden weapon forging drawings in my house, but I need to go back and find them carefully, so let's wait until tomorrow when I come back, I will bring you a little more forging drawings of hidden weapons, and I also happen to take a look at the power of this hidden weapon of hidden arrows." The designer said.

"Okay, good, this is the best, then you hurry back and find the drawings, the more such drawings the better, you try to find as many as possible, I don't know, these secret weapons are very useful for the war between the human and demon races in the near future, you can rest assured, I will report this matter to the first-level city lord, and let them give you a certain subsidy." Also, 'One Thought of Life and Death', you haven't come to study with me for a long time. Today is just with me to forge this sleeve arrow, you are the main forging, my master is enchanted, and you study hard when I enchant. Hopefully, I can learn these simple enchantments soon. Olaf said excitedly.
