Can life span be exchanged for treasure? I am invincible with infinite life span

Seeing this, Lu Qingan's heart became more certain of his guess.

"Tell me in detail."

Xu Qingying did not beat around the bush and said directly: "This seal repels any living creatures and objects that come close, because of its characteristics, it is extremely exclusive. But if it is a quantity or formation of the same attribute, the impact will be minimal. Do you understand what I mean?"

After hearing this, Lu Qingan's eyes suddenly flashed with a bright color, and then patted Xu Qingying's shoulder and smiled: "Well done! I roughly know how to deal with it."

At the same time, he also understood how the demons rescued the dragon. The so-called cat-for-the-brother is probably a certain formation that quickly replaces the dragon in the seal with the Liuli Realm corpse close to the seal, thereby releasing the dragon!

Xu Qingying said: "You have profound attainments in formations, so you should be able to construct a sealing formation with the same attributes, right?"

Lu Qing'an nodded slightly, but did not dare to fully guarantee: "I'll give it a try, but it will take a few days to recover."

He carefully looked at the dragon and basically determined that the dragon could last more than half a month. Half a month is enough.

Without saying anything more, Lu Qing'an took out a formation disk, which was an analysis formation he developed during his time. Although the level was low, it was extremely effective.

The characteristics of this sealing formation were quickly analyzed.

The properties were very strong, with strong repulsion. The most important point was that the inside contracted and the outside expanded.

It was obvious that the dragon was squeezed and its face was hideous under the seal, and its whole body was distorted, and the amount of external expansion made it difficult for all objects to approach.

After thinking for a while, he had already thought of how to give the dragon the final fatal blow.

He only needed to create a formation that could be integrated with the seal. Inside the formation, there were a large number of treasures that were about to explode. Once the formation was integrated with the seal, these treasures would explode inside the seal, and the dragon would be scorched on the outside and tender on the inside!

It was such a formation that he needed to find a way to create as soon as possible and put it into the experiment. Half a month was not a bit tight.

And he just tried hard and never let go of this opportunity to make a lot of life.

"Get ready to go back. But before leaving..." Lu Qing'an was going to go back and interrogate the three demons first, but before going back, he needed to do one thing, that is, to set up a formation to remind him here, as long as a living creature appeared here, to remind him in time.

The living creatures that appeared here were probably only the demons.

If what the Shadow Demon said was true, now that he had captured three demons, plus the Blood Demon himself, there were only seven demons in Panlong City.

"We have to deal with these demons in advance, so as not to disturb my plan."

After setting up a small formation, Lu Qing'an put Xu Qingying into the storage gold bead and left.

After Lu Qing'an left, the demon dragon was still cursing, but the voice was very small, only without rage.

From beginning to end, Lu Qing'an ignored the demon dragon.

In his eyes, this demon dragon was just an opportunity for him to become stronger.

After leaving, Lu Qing'an did not go back to the city mansion directly, but while thinking about how to create a formation with the same attribute, he wandered around Panlong City to look for traces of demons.

It took him several hours to return to the city mansion.

At this time, he had determined that the demons were hiding outside the city and were in Panlong City.

He could wait for an opportunity, or he could leave Panlong City and go to other cities to find Liuli Realm masters to kill them, and try to gather the bodies of Liuli Realm masters before the death of the demon dragon, and save the demon dragon from a dead end.

"No matter what, destroying these demons is a hidden danger after all."

Lu Qing'an shook his head. After a day of research, he roughly determined the direction of a formation.

The outside expands and the inside contracts, which is in line with the saying, heat expands and cold contracts.

Then his formation can try to create this classic physical theory.

The outside of the formation uses the same attribute of water, and the inside is ice attribute.

Just blend these two things into one, and it will probably be done.

After figuring out the mechanism, he began to study the array structure and array texture. To do this, he had to buy some high-level array texture books for reference.

So he left his residence and prepared to go to the Array Master Guild.

Just after leaving his residence, he suddenly received a voice transmission from Murong Qingming, asking him if there was any new progress in the Demon Search Array.

Lu Qingan replied casually, "Some, but there are still many difficulties."

After the voice transmission, he went to the Array Master Guild, strolled around, and bought a lot of books.

And when he walked out of the guild, he unexpectedly met Murong Qingming and Bai Lu.

When the man saw Lu Qingan, he quickly called him aside.

"Daoyou, are you here to solve the array problem?" Bai Lu asked, and he became more and more convinced that Lu Qingan was going all out to solve the problem of the Demon Search Array.

Lu Qingan nodded: "I bought some books and wanted to see if I could find a solution. What are you doing here?"

"My friend, an eighth-grade array master, is thousands of miles away, but he can meet me in a special way through a special array of the array master guild. I plan to send the manuscript given by Daoyou to him through this special array. Since Daoyou is here, if we meet together, maybe we can find the key to solve the problem."

Bai Lu originally planned to let Murong Qingming send a message to invite Lu Qingan to go with him, but Murong Qingming said that Lu Qingan was busy, so he gave up. I didn't expect him to come to the guild. It was really God's will.

"Special formation, special form?" Lu Qing'an's expression under the mask was a little strange.

He roughly guessed a possibility - could it be a 3D projection? Or can it transmit items, so convenient? This formation is worth exploring.

"Okay, let's go together."

Lu Qing'an nodded and followed the others to the depths of the guild.

At this time, a deacon came forward respectfully, as if he knew their purpose, and led the three people into a dark secret room.

Bai Lu took out nearly one million immortal stones and handed them to the deacon. The deacon immediately left the secret room and activated a special formation that cost 500,000 immortal stones.

Buzz!

A strong vibration came, and then a light gate appeared in the void in front of the three people. In the light gate, a light and shadow man walked out, wearing a white robe, with a mustache, and a kind face.

"Bai Lu, long time no see."

Bai Lu saw his friend thousands of miles away and said with a smile: "Old Long, this formation costs a lot, let's get straight to the point. This is the Daoist Jia I mentioned in the voice transmission."

At this time, Old Long shifted his gaze and looked at Lu Qing'an. After a careful examination, he smiled and said: "If what Bai Lu said is true, and if he really created that kind of wonderful formation, then Daoist you are really a genius."

While speaking, he praised Lu Qing'an more.

Lu Qing'an looked at this light and shadow man, and more wonderful ideas emerged in his mind.

The person who created this formation is also a genius!

Is this a complete 3D projection technology?

The future research direction of the formation is definitely a combination of reality and cultivation.

This will be a reform of the formation in this world!

"Daoyou is too serious. The formation is still in the conceptual stage, and many problems have not been solved." Lu Qing'an replied modestly.

"I will study the manuscript and maybe provide some suggestions for you." said Elder Long with a smile.

Bai Lu said, "I will send it over right away, but it will cost hundreds of thousands of immortal stones, which is really painful."

"No problem, the immortal stones required for transmission will be counted on me." Elder Long replied with a smile.

"Haha, thank you Elder Long." Bai Lu also refused and replied with a smile.

Bai Lu whispered a few words to the void, and the deacon outside the secret room activated another function of the formation again.

The buzzing sound started again, and a circular light gate appeared in front of Bai Lu after consuming 500,000 immortal stones. Bai Lu put the manuscript into it.

After a while, the light gate disappeared.

Lu Qing'an sighed secretly. This formation can actually transmit remotely, which is really amazing. However, the formation is not yet perfect, the vibration is too large, and it consumes too many immortal stones. If these problems can be solved, there will be unlimited prospects.

When his array skills improve, he can make a simpler and more complete array of the same kind.

"Okay, did you receive it, Elder Long?" Bai Lu asked with a smile.

"I have received it. Let me take a closer look." A man appeared on Elder Long's side and handed him the manuscript that had just been sent.

"Daoyou, there is still a cup of tea time after this array is activated. Elder Long and I don't have anything else to say. Do you have any questions to discuss with Elder Long?" Bai Lu asked Lu Qing'an at this time.

Lu Qing'an looked carefully at Elder Long who was studying the manuscript, and he muttered in his heart.

An eighth-grade immortal array master should find that the manuscript is okay soon.

And just when he thought of this, he saw Elder Long over there, and his eyes changed.

"What a wonderful array structure! Daoyou is really a genius!!"

Lu Qing'an was slightly stunned.

Well, I changed so much, deleted so much, and only a little self-created array structure is left. With just this manuscript, you are still so shocked?
