Transforming this level of formation is obviously a big project, the original plan has changed, Xu Chen had no choice but to come out and give everyone a bottom.

"I have to stay here for a while, it's not good if there is no one over there in Biancheng, the strength of the brothers can't keep up, so you should go!"

Xu Chen said this to Yang Ziyun, but Yang Ziyun, who had been silent all along, suddenly broke out!

"Why do I want to do everything? Why do I do so many things and am I not as good as the person who doesn't do anything? Am I so easy to bully?"

The inexplicable anger made Xu Chen really confused, looking at Yang Ziyun's appearance of wanting to cry without tears and looking aggrieved, Xu Chen's heart moved, and he wanted to say something, but when the words came to his mouth, he didn't know where to start.

Song Yongping is a master of the love field, and he can see the signs at a glance, but he mistakenly thinks that the "person who doesn't do anything" in Yang Ziyun's mouth is Zhao Ruoxi. Thinking that he was now a person on the same boat, Song Yongping said: "If Brother Xu is relieved, let me go to Biancheng! I have also seen the things handed over once, and I will send you the next ones in a flying boat!"

Xu Chen heard this and said with a smile: "It's great that Brother Song is willing to help!"

Song Yongping smiled: "It's just a gesture!"

After Song Yongping took Marco away, Xu Chen led the rest of the people into the empty cave where the tree demon was located in the center of the mountain.

Xu Chen hurriedly beckoned Song Qing and the others to help him sort out the tool table, prepare props, measure the formation patterns and other things.

This kind of thing Xiaoshi can't help, and he is boringly feeding the little flower deer, which is also amazing, this ordinary little flower deer in the outside world actually began to be able to breathe normally in the remnant area here after eating a few bottles of Zhao Ruoxi's Spirit Beast Pill!

Xu Chen asked Yang Ziyun to investigate, and this little flower deer could only be regarded as having some aura accumulation in his body, which was far from reaching the point of cultivation.

Originally, Xu Chen planned to ask the Tree Demon how ordinary animals produce spirituality and even spiritual intelligence, so as to analyze how this little deer has adapted to the oxygen-free environment here, and how the little white pigeon has become full of intelligence at the beginning, and even whether this pigeon will evolve in the future, or cultivate into a "monster" that can speak people's mouths.

It's just that now the transformation of the formation is very important, and neither Xu Chen nor the tree demon has the heart to care about such trivial matters as whether a deer can breathe or whether a pigeon can speak.

The rest of the people found a place to rest on the spot, while Yang Ziyun was still angry on the sidelines.

It was the tree demon, seeing that Xu Chen really started to grope for the runes on the big array, he didn't have any bottom in his heart.

"Can you kid do it? I can tell you! Look, if you want to do it, you must at least convince me first! This big array can be linked to Lao Tzu's life, if you kid dares to mess around, Lao Tzu will tear you alive!"

Just like that, the tree demon said it so politely in the face of the two holy spirits, White Tiger and Xuanwu. If someone else says that this formation is going to be moved, how can the tree demon say this?

Xu Chen didn't raise his head, still groping on the wall, and said with relief: "You can rest assured! I will explain it to you after I think of the plan, after so many years, this formation has long become a part of your body, speaking of which, you are also a formation master, whether my plan works or not, you must naturally know best!"

Hearing Xu Chen say this, the tree demon was a little relieved, but it was just a little more relieved, and his eyes were still staring intently at Xu Chen's every move.

This space is the core of the entire formation, and it is also the gateway to enter and exit the outside world.

Three-dimensional space is composed of countless planes, if each plane is analogous to a piece of paper, all the remnants are the part of these papers folded into, which cannot be seen on the surface, but is always connected to the outside world, and has not been separated from this heaven and earth, becoming an independent space in the void.

Unlike the lost space, or the Cave Heaven Blessed Land created by the monks using runes and formations, which is just a false space, the remnants of the realm surrounded by the formation are real heaven and earth, and if the formation dies, the space protected by it will be completely exposed.

Therefore, the formation is like a protective shield, protecting the monks in it, without the protection of the large array, the toxins from the outside world will invade instantly, and everything in the remnant domain will be wiped out.

The matter of life and death cannot be left unscrupulous. Looking at Xu Chen's investigation in a similar manner, the tree demon's browless brow was still inevitably deeply furrowed.

After looking at it for a long time, after surveying all the runes on the surrounding walls, Xu Chen pondered for a moment, looked at the tree demon and said, "The runes here shouldn't be all of them, right?"

The Tree Demon said indifferently: "You just want a window that opens and closes freely, do you need to know all the runes?"

Xu Chen smiled and replied, "You also know that a large array is composed of countless runes, and the mutual cooperation between runes and runes finally makes the big array have the function it should have. ”

"I can transform all the runes if I don't know all the runes, but if there is any bad reaction between the transformed runes and the runes I don't know......"

Xu Chen's words were not finished, but the tree demon's brows frowned even tighter.

Out of caution, the tree demon naturally didn't want Xu Chen to know all the runes, after all, the big array had been integrated with him, sharing weal and woe, and revealing his details in vain, Xu Chen would not do this kind of thing, not to mention the tree demon who had lived for an unknown number of years!

But now, if you don't agree, as Xu Chen said, if the information provided is insufficient, so that the transformed runes are incompatible with the original runes, and even have some bad reactions, then it will be a big trouble!

But if you don't agree with Xu Chen's transformation of the formation, and don't agree with Xu Chen setting up a stronghold in the Heavenly Wolf Valley, wouldn't you be taking the orders of the two holy spirits as a child's play?

After much thought, the tree demon finally agreed to Xu Chen's request.

With a wave of his hand, the Tree Demon's body turned into a sky full of green light, and the green light regrouped into twisted runes, floating around Xu Chen.

For some reason, when Xu Chen wore the jade pendant, his memory was unusually good, and it didn't take long for the runes in the sky to be clearly engraved in Xu Chen's mind like an imprint.

Countless runes were broken down in his mind, and among the countless lines, Xu Chen was trying to find the most essential one.

The functional structure of a large array of this scale is extremely complex, and it is impossible to do it in one go, no formation mage can rely on the strength of one person to complete the current scale of the large array independently, let alone complete all the runes without stopping.

There are thousands of threads, there are too many breakpoints, and the age is long, even if Xu Chen has divided the entire large array into several parts, it is still difficult to accurately find out the point where he first put his pen down.

The runes have been memorized, and the rest is all about water grinding.

In front of the workbench, Xu Chen began to be busy day and night again, and there was no day and night in this space.

Looking at the busy Xu Chen, Yang Ziyun's heart was sour.

Walking to Xu Chen's side, Yang Ziyun said softly: "Take a rest! The battle is over, there is no need to work so hard!"

Xu Chen didn't raise his head, and replied: "I'm not tired, let's wait a while!

"How can you not be tired?" Yang Ziyun said anxiously: "You have only a handful of time to sleep in the past month or so, and if you continue to hold on like this, your body will collapse!"

Before entering the lost space, when he was in Tiangong Sect, Xu Chen was busy day and night, and in the last month, in order to prepare for the war, Xu Chen had less than an hour of rest every day.

After a long period of exertion, Xu Chen's body should have collapsed a long time ago, but he kept taking pills and forcibly kept his body in a state of excitement by taking drugs.

After practicing, the monk can naturally go without eating, drinking, or sleeping for a long time, but Xu Chen is not a monk after all, even if the elixir can keep the body in a state of excitement, but the mental exhaustion is accumulating day by day.

Before the war, Yang Ziyun didn't say much, but now that the war is over, she is not ready to let Xu Chen squander her body like this!

"Don't look at it!" Yang Ziyun scolded with a straight face: "Give me a rest!"

"Don't be verbose, it'll be right away!" Xu Chen said impatiently.

"Are you going or not? Believe it or not, a stick will knock you out!" Yang Ziyun said angrily.

After speaking, he reached out to pull Xu Chen.

In the middle of the pull, several neatly arranged white papers on the table were messed up, and the runes drawn on them overlapped, and a new pattern appeared!

Suddenly, Xu Chen's eyes lit up and he shouted, "Don't move!"

Yang Ziyun didn't want to listen to it, but seeing Xu Chen's surprised look, the strength in her hand unconsciously decreased.

Xu Chen, whose eyes were glazed, fell into deep thought, and after a long while, Xu Chen's hands flew quickly and he was busy again, but this time his face was full of surprise after decryption.

Soon, a new blank sheet of paper was born, and a new group jumped on the paper.

Although it has been much simpler, the patterns on the white paper are still dazzling.

"Haha!haha!" Xu Chen finally couldn't help laughing: "It's out! It's out! The prototype diagram finally let me find out!"

Hearing the laughter, the tree demon flashed over, looked at the simple pattern on the white paper, and frowned, "What do you say this is?"

Xu Chen, who was excited, didn't raise his head and said, "Prototype map!"

The Dryad asked, "What is the prototype?"

Xu Chen replied as a matter of course: "This big array!"

The Tree Demon frowned and said, "Don't you know the runes, and what is the resemblance between the patterns on this and the runes on the Great Array?"

Xu Chen was slightly stunned, looked up at him, pondered for a moment, and decided to tell the truth: "All the runes you know are obtained by combining the basic runes with each other, and some will add some purely decorative lines to cover up the original runes. But what you don't know is that even the basic runes can be broken down again!"

"What did you say?" the Dryad exclaimed, "What do you mean...... Did you break down the base runes?"

Facing the terrifying expression of the tree demon, Xu Chen nodded confidently and smiled: "Not bad!"

"This can't be!" said the Dryad's face was full of surprise and disbelief.
