Xiao Er knocked on the door outside, and it took a while for the door to open.

Looking at the white and chubby, lust-obsessed face, it was the person Fu Yun was looking for, the fat man Zhou Ning.

"Yo, Brother Fu is here, come on, come in and have two drinks. ”

Zhou Ning was also very happy to see Fu Yun coming, so every time he came, he would be surprised, and hurriedly greeted.

"Two drinks are free, this time I came to ask for advice. ”

The shopkeeper made way for him, and Fu Yun walked into the private room.

At the entrance, sure enough, Feng Qingyu, Boss Mi, and Chen Hua were also there, but unfortunately the cute girl named Ye Xian'er was not there.

"The little brother is here, do you miss your sister? ”

Senior Sister Qingyu is still so heroic, she is still wearing a low-cut crop top and a hot little skirt, and Boss Mi is fascinated when she sees it.

Fu Yun didn't speak, and directly took out a self-made new flame talisman and placed it on the table.

This time, Feng Qingyu didn't do it first, it was Zhou Ning who fished out the spirit talisman in his hand, and looked at it back and forth, left and right.

"Like, so like! I didn't expect you to do it so quickly. ”

After a little temptation, the fat man Zhou Ning was taken aback again. It's too similar to his own spirit rune, and he even dares to use wood to make fire to infuse spiritual energy, this kid is fat enough.

Feng Qingyu took the spirit rune for the second time, and after some observation and temptation, he was also amazed by Fu Yun's talisman making ability.

"There's one thing I'd like to ask. ”

Fu Yun slowly expressed the idea of connecting the spirit pattern to the flame talisman, as well as the bold imagination of the self-made rune paper cannon.

"Okay! My little brother is really daring, my sister likes it. ”

After listening to the words, Feng Qingyu slapped the table and stood up, agreeing with Fu Yun's idea.

Boss Mi didn't care much about the spirit rune, he was more concerned about Senior Sister Qingyu's chest rising and falling because of excitement.

The two little eyes narrowed even more at this time, looking directly at the violently undulating curves under the tights.

Ahem!

Zhou Ning changed his image as a fat man, and talked about the knowledge of spiritual patterns seriously.

After hearing this, Fu Yun's eyes couldn't help but light up.

There is indeed a spirit pattern that can connect to the flame rune, and this spirit pattern is commonly found in the cultivation realm's large weapon, the Spirit Gathering Cannon. It's also something like artillery, so powerful that it can destroy a city.

But this weapon has high requirements for materials, and it is required that it itself can withstand a vigorous bombardment.

Even so, you have to fire one shot at a time, and every time you release a shot, you have to pause to regather the aura, and then turn the gathered aura into flames, thunder and lightning and other lethal attributes to attack again.

And Fu Yun's paper cannon naturally can't be compared with the Great Killer Spirit Cannon of the Xiuzhen Realm in terms of material, and its power is far behind, but the advantage is that it can be fired continuously without gathering spiritual energy, and it is extremely convenient to carry and release.

If the ten paper cannons are in terms of group lethality, they are not weaker than the monks of the Gathering Period. Of course, if it is controlled by multiple Qi Refining Stage cultivators, it can exert greater power.

And how to ensure the stability of the talisman in the process of making talismans is still the biggest problem of this kind of talisman, and it is also the problem that Zhou Ning is most worried about.

A dozen or even dozens of flame talismans are connected together, which is very different from the meaning of three or two

。 If anything goes wrong during this period, it will be fatal.

The more runes there are, the more difficult they become, and each rune increases the danger.

As for this question, Fu Yun has already thought about it.

Flame runes on paper cannons can be spaced together. There is a gap between one rune and one rune to connect the spirit pattern, or two runes next to each other and then use the spirit pattern to connect to the third one. If more than a dozen runes were next to each other, then he was not sure that he could do it well.

After some discussion, the structure of the paper cannon has already taken shape.

Zhou Ning took out another book and reluctantly handed it to Fu Yun.

"This is not a gift, I can only lend it to you, remember to return it to me after reading it." "There was a bit of pain in his speech.

When Fu Yun heard this, he raised his eyebrows, and when he looked at the cover of the book he received, he couldn't help but be secretly surprised.

There is no title on the cover, but in the lower right corner it reads: Cult Works.

At first glance, I knew that this was a very valuable book, not the kind of big road goods that were on the stalls outside.

The Evil Venerable is just a nickname, no one knows his real name, and his biggest hobby is to make all kinds of strange things, such as traps, spirit cannons, traps, flying machines, and so on.

Although this is a paper book, it seems that the material should not be ordinary paper, and the texture is strong and tough.

Fu Yun took a cursory look at it, and there was really relevant knowledge about the production of the Spirit Gathering Cannon, but it was only a rough introduction, and there was no detailed production steps.

It's right to think about it, the spirit gathering cannon, the kind of cultivation realm killing weapon, how can it be easily taught to make it.

Even if someone teaches, not everyone can learn it.

Fu Yun flipped down again, and saw something familiar.

Huh, this machine man looks like the guards in the sect!

Could it be that the iron-clad guards and bronze-armored guards of the Qingcheng faction are all organ people?

It's quite possible, because these guards stand there all year round, not eating, not moving, and only occasionally say a few words, maybe someone manipulated it, or they used a method like a thousand miles of sound transmission.

Seeing this, Fu Yun already understood the preciousness of this book, although it was only a rough introduction to knowledge and no detailed production methods, but its value was also very high, and ordinary people might not be able to buy it even if they had spirit stones.

Zhou Ning was so generous that Fu Yun couldn't help but feel a little flattered.

The two have not known each other for a long time, and they actually lent him such a precious book, and they were not afraid that he would take it and run away.

Fu Yun thought to himself that when he had figured out the paper cannon thoroughly, he must be the first to show it to Master Zhou.

At this moment, in Fu Yun's mind, Zhou Ning has risen from a fat man to a talisman master.

"Then I'll take my leave, and come back if I have any questions. ”

Fu Yun remembered that he still had an appointment with Senior Sister Luo, and hurriedly said goodbye.

"Eh, little brother, don't hurry to leave, stay here and drink together. ”

Feng Qingyu is really a rice boss who is not an outsider, and he eats and drinks for nothing in the private room of Zuiyue Building, and he also brings it with him and invites others to join him.

"Uh...... Another day, someone is waiting for me at the market. ”

If it weren't for the appointment, Fu Yun really wanted to drink some wine, and by the way, he tasted the signature drunken crab of Zuiyue Tower, he didn't come to Zuiyue Lou to eat during this time, and he was really a little greedy.

"Yo, it's a little girl, so I won't delay you. ”

Fu Yun felt a chill, this woman's intuition was too accurate, and she didn't say anything before she was seen by Senior Sister Qingyu.

Scratching his head embarrassedly, he said goodbye to everyone again, and hurried downstairs.
