"There are such great teachers...... Could it be that the record was really broken just now!"

If before, everyone was still a little skeptical about whether he really broke the record, and when they heard that there was such a powerful teacher, even Hall Master Mo and Elder Mi were impressed, and they all had doubts in their hearts.

Famous teachers are more than six stars, and the means are becoming more and more terrifying, and there are more and more of them, and many abilities are not something they can think about.

Because of this, the descendants of those saints are so powerful, far surpassing their peers.

The starting point is high, and the knowledge and eyesight are far beyond ordinary people, and many things, even if they want to, they can't think of them.

"Thank you!"

Hearing his promise, Zhang Xuan breathed a sigh of relief.

Since others can refine it, he may be able to cultivate it, and if it is repaired, he can save a lot of money!

As long as you don't spend money, you make money!

It's too poor to squander it at will.

A few steps back to the ruins, he took a deep breath and reached out to touch it.

Just now I only used the Eye of Reason in it, and the Heavenly Dao Library hasn't used it yet, so now use this thing to see what is going on with this passage, and whether it can be repaired.

Although the passage has collapsed, the walls are still there, and all kinds of mechanism springs are connected into a whole, and if you touch it with your hands, you can form a complete book.

"Flawed!"

With a soft shout in his head, there was a shaking, and a book appeared in front of him, and Zhang Hang looked at it.

Immediately after, his eyes narrowed.

The reason why the passage collapsed was because the ore that maintained the power was consumed, the balance of the formation was broken, and there was only one way to repair it, and that was to find four more pieces of core flood rock...... Then the formation was patched up and the balance was rebuilt.

Tinkering with formations and building balance, he can do it, but he can ...... Where to find the geocentric floods?

Not to mention the scarcity of this thing, every moment is worth a fortune, and his current net worth can't afford one, let alone four.

"Unless it can be solved...... You have to use the flaw of the Earth's Core Flood!"

Bow your head in contemplation.

The books in the library regard the core of the earth as a defect, because this thing is too valuable, but the effect is not the best, if it can be replaced with something else, and the value is not high, it will be easy to solve.

It's just that...... How to replace it, how to replace it, he really doesn't know much about this kind of mechanism, and after thinking about it for a while, he doesn't know why.

I couldn't help it, so I turned my head: "This elder, there is something to ask for ...... below."

Although I don't know who this old man is, he must be an elder, and there must be nothing wrong with calling him so.

"What's the matter?" I don't know what kind of moth this guy is going to have, Yuan Hong frowned.

"That's right...... I've just observed that I have some understanding of this channel, but it's just ...... There are still some places that I don't understand, I don't know if our refining academy has any books on this subject, can you lend them to me?"

If you don't understand, there is only one way, find a book to generate a Heavenly Dao cheats.

For others, it is to sharpen the gun on the spot, but for him, it is the most effective method.

"Reading a book?"

Yuan Hong was stunned.

The passage collapsed like this, and I thought about reading a book...... Will it be too late?

"What type of books do you need?" Although he felt that this guy was unreliable, Yuan Hong couldn't help but ask.

"As long as it's about the Earthfire Passage, the more there are, the better......" Zhang Xuandao.

Hearing that this guy didn't even have a goal, Yuan Hong had a black line, paused, and finally turned his head: "Luo Yan, you go to the library and take all the books about the Earth Fire Channel!"

If you were someone else, you would definitely not be treated like this, this guy took out Elder Mi's token, and there was a powerful teacher, although he was full of depression, he still endured it.

Of course, the most important thing is that he also wants to see how to solve the problem that the earth fire passage has collapsed like this.

"Reading? What can you understand by reading a book?"

"yes, I don't understand, I guess I want to see the structure!"

"The Earth Fire Passage is not a secret, the most important thing is the four Earth Core Flood Rocks, it is said that in order to get this thing, it cost a huge price, as long as this thing is not damaged and repaired, it is not difficult!"

......

Hearing that the young man had turned around and wanted to read a book, everyone was full of doubts.

Although books are the ladder of human progress, there is no one to guide them, and it is impossible to learn a profession completely just by reading books.

I have never heard of someone who can become a peerless genius behind closed doors.

Listening to the other party's vow to try to repair it, I thought that there was research on refining tools and heavenly work, and it could really be solved, but I didn't expect that I didn't say anything, and I went to sharpen the gun......

If the gun was really so easy to sharpen, it would not be so angry that Vice President Yuan Hong would be so angry.

Ignoring the strange eyes of everyone, Zhang Xuan waited quietly, and after a short time, Luo Yan walked back again.

The books about the earth fire passage are basically put together, and it is not complicated to find, and when he came to him, after getting the teacher's confirmation, Luo Yan flicked his wrist, and hundreds of books were piled up in front of him.

These books are all about the Earthfire Channel, some of them are marked with structures, some are marked with how to use them, and some are written with suggestions for changes...... A lot of it is the words of one family, and if you can't distinguish it, let alone absorb knowledge, after looking at it for a while, you will be dizzy and don't know why.

Coming to the books, Zhang Xuan exhaled a breath, touched each one, pretended to be looking for some book, and after a while, he touched them all, picked up one casually, and slowly opened it.

His eyes did not fall on the books, but he concentrated his mind and formed the Heavenly Dao Exercises with the many books he had just collected.

Call!

A book appears, holds it in front of you, and opens it casually.

"And so many flaws?"

I glanced at it and rolled my eyelids.

The number of books about this passage is a little too small, and it has not been completely completed in the half day of sorting, and there are defects everywhere, as many as fifty-two!

However, the number of defects is nothing, the main thing is whether it can replace the core flood rock with something else.

Read quickly, and quickly turn the book to the flaws of the geocentric flood.

"The scarce number of geocentric floods is the biggest defect of the channel, if it can be replaced by the core fire, it can reduce countless costs, and the firepower is still endless, but the geocentric fire is the fire of the earth, which is difficult to control, and the firepower is slightly weaker......"

I wrote more than a page.

Although it can be replaced by the fire in the center of the earth, it also has many flaws and is not easy to complete.

First of all, the temperature of the geocentric fire is not enough, and it cannot reach the level of the geocentric flood!

There is only one way to make it have the same effect, and that is ...... Use the auxiliary array.

The formation diagram of the auxiliary array, which is on one of the books, is a five-star formation, and with the strength of Zhang Hang now, it can be done completely, but it is ...... This formation, which is in conflict with the previous formation that maintained balance, is easy to conflict, and once it is not handled well...... There is a risk of causing an explosion!

Therefore, the formation of the Earth-Fire Channel by the Earth's Core Fire is only theoretically feasible and almost no one can complete it.

The balance point of the two conflicting formations is difficult to find, even if the real formation grandmaster wants to complete it, it is impossible, let alone the person who built the passage in the first place.

Because of this, in order to be safe, it is necessary to spend countless costs to find the core of the earth.

But...... It's hard for others, but it's easy for Zhang Hang.

Isn't it just a balance?

It seems that he started with this......

Break the formation, clear the level, and clear the pool...... It is all by finding a balance point that it can shock everyone and spread its name all over the world.

"It's just...... There are not enough books, this balance point, it may not be as easy to find as before, but as long as it is successful, it is equivalent to earning 10 high-grade spirit stones, no matter what, you have to fight it!"

Zhang Hang nodded.

The Earth's Core Fire is not only a balance of auxiliary formations, but also has other flaws, such as being far less stable than the Earth's Core Flood Rock, and the power output is not very uniform......

Although there are not enough books and there is no writing on how to solve it, as long as the big problem of balance is solved, nothing else should be there.

"Okay, it's on fire!"

After scrutinizing it a few times, it didn't feel like there was much of a problem, so Zhang Hang stood up again and exhaled a breath of turbidity.

"This elder, I don't know if we are here, is there a way to connect the fire of the earth's heart?"

"Earth's fire?"

Yuan Hong nodded: "A lot of times, refiners need the heat of the earth fire to smelt metal, this thing is a must-have thing for the refining academy, the same as charcoal fire!"

When refining tools, many metals are difficult to melt, and ordinary charcoal fire can't do it at all, so you can only use this.

Therefore, there is a large array here that specializes in attracting earth fire, and it is not difficult to bring this thing over.

"Great......"

Zhang Hang's eyes lit up: "I want to borrow this thing for use, and I hope Elder Yuan can help bring it over......"

"Connecting the Earth's Core Fire? Do you want to use this instead of the Earth's Core Flood?"

Yuan Hong frowned.

"Yes, I've found the exact way, don't worry, it will definitely work!" smiled lightly, and his face was full of confidence.

"Good!"

Seeing what he said, Yuan Hong hesitated for a moment, and finally nodded.

Although the earth fire is dangerous, it is often used by the refiner, and with his ability, it is not too difficult to control, and there should be no danger.

Since this guy said that he could succeed, he just wanted to see it.

If you really want to complete it, it can be said that you have completed what many predecessors have not done before, and it has really broken the record.

Turned around and walked out, after a short time, he took a metal array plate, said hello and put it on the ground casually, and with a flick of his palm, a stream of true qi poured into it.

Airplanes!

The array patterns on the array swirled, and everyone immediately felt a scorching geocentric flame, like a fire dragon, gushing out from the middle, as if it was about to melt the air.

Many of the elders of the Refiner Guild used this kind of array plate as charcoal, and they didn't know how many times they used it, and they were familiar with it.

"Thank you!"

Exhaled a breath and smiled softly.

This core fire, the temperature is indeed much worse than the previous core flood rock, it seems that the book is good, if you want to really repair the channel, you must use the auxiliary formation to increase the temperature.
