"Hong Kui, how did you do it?"

Seeing that those papers with strange marks on them could really recognize the shadows, Qin Long was in a good mood. Now his personal safety was guaranteed.

Although the response to the fire was a little slow, it was a leap from scratch. I believe it won't be long before Hong Kui can make these things timely.

"It's very simple."

Hong Kui took out a piece of white paper again and said: "The shadow is black, and I use these black marks to simulate the color of the shadow to draw the formation. These stripes are the formation paths. Once the shadow enters, these formation paths will be connected.

, and then activate the formation to make the paper burn."

"sounds good."

Although it is different from what Qin Long imagined, Hong Kui's ability to use this special method to create formations just illustrates his genius.

When Hong Kui was praised, a smile appeared on his face, and he immediately said: "It's just that there are still some flaws that cannot be solved."

Qin Long disagreed. It was normal for new things to have flaws, which just showed that there was room for growth.

"Tell me what the flaw is?"

Hong Kui: "This formation method for identifying shadows is relatively weak and can only be engraved on paper. If it is replaced with other materials, it will be too powerful to be used."

"What? Can't we find a way to increase the strength of the formation? Or can't we use it as a primer to activate other formations?"

It's too impractical to just draw on paper. Is it possible that my house will be covered with white paper in the future, and even this small flame cannot block the "shadow"?

Hong Kui shook his head: "No, I have already tried using other materials but they all failed. If I want to only recognize the shadow and be able to carry the formation, this is the only way."

"Only recognize shadows? Do you mean that these formations cannot recognize anything except shadows?"

"Yes, these formations can only be triggered by shadows. Everything else, whether it is spiritual energy or object contact, will not affect the formation itself."

This...this thing is very wrong. It's very problematic from the starting point.

Qin Long thought of something: "Hong Kui, are you thinking in the wrong direction?"

Hong Kui originally looked happy to be praised, but when he heard what he said, his face instantly dropped: "Impossible. Since my formation can already recognize shadows, it means there is nothing wrong with it."

As a cultivation expert himself, Qin Long didn't want to cause trouble with him, so he quickly explained: "That's not what I meant. There must be nothing wrong with your formation. I just wanted to say whether there are some things that you haven't considered comprehensively.

"

Hong Kui's face looked better now. Qin Long had been kind to him, and he also felt that the change in attitude just now was a bit inappropriate.

"What are the things Lord Molong is referring to?"

Hong Kui believed that there was nothing wrong with his formation. He could recognize shadows and activate the formation at the same time. This was something that most formation monks could not do. He did not think there was anything that needed to be modified.

Qin Long thought of the stealth fighters and anti-stealth radars he had heard of before. Although there were not such outrageous things in the world of cultivation, the "shadow" technique was no different from that of stealth fighters. And he wanted Hong Kui to do something

It's an anti-stealth radar.

The key to a stealth fighter being invisible is that it absorbs the signal emitted by the radar. If the radar cannot receive the signal it sends, it will naturally not be able to see the fighter jet.

The working principle of anti-stealth radar is also very simple. The reason why it can resist stealth is not that it can directly "see" stealth fighters, but that it can detect everything except stealth fighters, and stealth fighters swallow up all signals. , the radar also indirectly saw it.

In this way, the stealth fighter turned into a shadow in the sun and was easily discovered. Junqu Pavilion

The above situation is very similar to now, but the gap between science and cultivation is thousands of miles away. It was only because of Hong Kui that Qin Long realized that there was actually a connection between the two.

"Hong Kui, do you think this can be done..." Qin Long replaced the metaphor of fighter planes and radars with formations and shadows, and simplified the relationship between them to Hong Kui.

The substitution of metaphors was too big, and Qin Long could only explain it while talking. Although his explanation was stumbling, it set off a storm in Hong Kui's ears.

His expression quickly changed from complacency at the beginning to shock.

"How can it still be like this!"

Why use an array to filter all spiritual energy signals between heaven and earth, and then use an array to filter out those signals as a basis for not activating the array. In the end, the unrecognizable signals will naturally turn into shadows, making it confusing. inside.

Hong Kui became excited. He secretly knew that the method Qin Long said was feasible, but he couldn't understand the words at all, and his big eyes were full of doubts.

What is a signal, what is a compilation, what is binomial logic? He can understand every word Qin Long says. However, those combined words make Hong Kui feel strange and mysterious.

Hong Kui's eyes were gradually filled with admiration. Master Molong was really powerful. I think these things must be knowledge that only a true formation monk can master!

Hong Kui grabbed Qin Long and said excitedly: "Master Mo Long, please teach me!"

...

When leaving Hong Kui's house, the sky outside had already matched his decoration style.

After rubbing his head that started to throb, Qin Long couldn't help but sigh. It turns out that being a teacher is such a complicated thing.

Hong Kui had so many questions that Qin Long almost dug out his own brain to barely answer his doubts.

The two of them were stuck for nearly an afternoon on how to convert the things detected in the formation into signals.

In order to solve this problem, Qin Long even dug out the basic programming course that he had studied a long time ago, and used a lot of confusing knowledge to finally smooth out Hong Kui's ideas.

What is worth celebrating is that all the hard work has paid off, and Hong Kui has already begun to set up a new formation.

Qin Long hoped that he could succeed once and for all so that he would not suffer this kind of torture again.

"Lord Molong, let's discuss the nesting of formations tomorrow. No matter what I do, I can't install one formation within another formation."

Qin Long almost slapped himself on the forehead, he really didn't want to think about this issue!

But when it came to his own life and safety, Qin Long could only nod.

"Okay, let's discuss it tomorrow. I'm a little tired. I want to go out and relax." After saying that, he quickly ran out of the house. He finally understood why Lin Fan didn't want to be with this guy. It was too terrible.

"Shouldn't you go back to bed when you are tired? Why should you relax?"

Hong Kui couldn't understand what he was doing, so he muttered and went back to the house to continue studying his formation.

Outside Shiyu City,

Qin Long hid in a hidden place in the wilderness. He had already made sure that there was absolutely no other person in this place except himself, so he took out the Shadow Killing Order and combined it with his gossip.

This is his daily compulsory course. Although the probability is very small, he still wants to confirm whether "Shadow" has found someone to snatch the token back through the Shadow Killing Gate.

The reason why Qin Long chose the wilderness was mainly because he was worried about the tracking function of this token. The Shadow Kill Token can communicate over a wide range. In the world of cultivation where communication relies entirely on travel, it is considered a treasure among treasures. Shadow Kill Menan has several positions.

The functions above are not unusual at all.

This is also the reason why he insists on living near his home. After all, the token is still in Shuangyue's hands. If it is not activated, it can be tracked. Shuangyue can temporarily act as a shield.

In order to avoid being approached by the other party, Qin Long will come to the wilderness every time he activates the Shadow Killing Order. This is the third time he has changed places tonight. The Shadow Killing Order is still blank. These shadow owners don't seem to like it.

Chatting in the water group at night.

Just when Qin Long was about to go home, a line of small words suddenly appeared on the surface of the jade pendant.

[Ling Jiu: The latest news is that Shiyu City has changed owners. The new city lord is named Shi Kai, who is the son of the former Shiyu City lord. He teamed up with Shuang Yue, the deacon of the Li family, to stop King Yao’s plan. Shiyu City is now half-destroyed and is being rebuilt.

】

Qin Long's eyes narrowed. Ling Jiu was very fast in getting information. In just two or three days, he had figured out the general movements of Shiyu City.

"Is it possible that there are still people from the Shadow Kill Sect left in Shiyu City, and they happen to be Ling Jiu's subordinates?"

The Demon Wolf's attack on the city was almost successful. If someone from the Shadow Kill Sect was stationed in Shiyu City, they should help King Yao. Even if he didn't help, he would just stand and watch the show. There is no reason for him to help the monks defend the city. There are only disadvantages to doing so.

No benefit.

[Ling Qi: We shouldn't have helped King Yao seize the city in the first place. Kuang Gui Dou and this guy have been plotting against human souls from the beginning. Now that they have decided to join the Shadow Killing Sect, they still dare to plan a massacre of the city in a big way, even if he is not captured by Ling Kong

I will also destroy him who was killed by the sun, and Kuang Gui will definitely cut him into pieces.】

Qin Long was a little surprised. He didn't expect this Seven Shadow Master to have a sense of justice, and he was also guessing about his strength.

Ling Qi said that he wanted to destroy the Medicine King. This Medicine King should be the Medicine King who became the Shadow Master after the successful massacre of the city. According to this calculation, Ling Qi should be able to defeat the first-level monks of the Divine Pill, and his strength should be about the same as that of human immortals.

However, killing the Medicine King does not necessarily mean killing him, it may also mean expelling the Shadow Killing Sect. If you simply want to defeat the Medicine King, you don’t need a human immortal. The later stage of the divine elixir is enough. I estimate that Ling Qiyin should use the divine elixir to reach humans.

The monks around the immortals.

[Ling Jiu: There is no need for you to destroy him. Not only Kuang Gui Dou, but also King Yao is dead. Even his body was blown to pieces because he absorbed too many human souls and turned into a human soul tiger.

】

"Where did Ling Jiu get this information?"

Qin Long naturally knew what the final fate of Medicine King was. He could see clearly in the fireball that those human souls gathered into Medicine King's body when the last batch of demon wolves hit the city wall, and then he turned into a demon tiger.

.

But Qin Long has time, which doesn't mean that others also have time to pay attention to this. Few people should know about Medicine King's changes.

[Ling Qi: I turned into a human soul tiger, how did you know? 】

[Lingjiu: Hehe, you can’t control this. I know a lot. I also learned that there is a bigger secret hidden in Shiyu City. Do you want to know? 】

"The secret of Shiyu City?"

Qin Long's curiosity was aroused, and he couldn't help but want to ask Ling Jiu what the secret was. He was in Shiyu City now and said that he couldn't keep the things involved in this secret as his own!

In my heart, I was hoping that a shadow master would come to ask me what the secret was, and a line of small words appeared on the surface of the jade pendant.

【Ling 7: Love to talk but don't talk.】

Qin Long almost made Ling Qi vomit blood. If you don't want to know, just go and cool down. What are you doing here? I wonder if people like Ling Jiu are in need of support. As long as you say a few words, he will pour out all the beans.

What do you do to stimulate him?

Ling Qi's words silenced Yupei.

Qin Long was so anxious now that he wished he could pull Ling Qi out and beat him up right now. It was so awkward and awkward, just like listening to a cross talk that was exciting and a storyteller breaking it down next time.

After a long time, someone finally couldn't hold it in any longer.

[Ling 10: Tell me quickly, what is it? 】

It seemed that Ling Shi's appearance gave Ling Jiu great satisfaction, as successive words continued to appear on the jade pendant.
Chapter completed!
