This search for the ruins is not a matter of one person, it involves a lot, and even involves the entire human race, so the Qingyuan Famous Master Hall attaches great importance to it, not only sending Master Wu, but also sending a seven-star peak formation mage to help everyone break the seal and find the right path.

Although his uncle is young, he is bold and dares to do anything, so it is better to explain in advance to avoid unnecessary trouble.

"Don't worry!" Zhang Xuan nodded.

Seeing his confident face, Mu Shi didn't know how to answer, and looked at Luo Ruoxi not far away, but saw her smile slightly, as if he didn't believe in this guy's assurance.

No wonder.

When I took him to the Holy Altar and asked him to have more respect, the result was that the entire rock wall collapsed, and if it wasn't for Master Confucius's voice, I am afraid that he would have been beaten to death.

This guy is sometimes amazingly talented and extremely smart, and sometimes, he seems silly and cute.

The three of them chatted casually, and Zhang Hang asked some more about the ruins, and learned that this might be related to Master Confucius, and his heart was full of excitement.

Last time, I had already asked Master Confucius in person, and I knew that the other party also had congenital fetal poison in his body, and since it was related to him, he might be able to find clues.

There were no words all the way, and the flying holy beast was extremely fast, and five days later, he saw Huoyuan City appear in front of him.

"Fire Source City is already scorching, and now it's summer again, if you don't have a cultivator, it is estimated that it will be unbearable......"

Looking at the city not far away, under the sunlight, the city is slightly reddened, Mushi Road.

"It's hot enough!"

Feeling the temperature around him, Zhang Hang nodded.

Jingyuan City, which I just went to a few days ago, snowed all day long, cold as ice, but here is like a furnace, if you don't come in person, you will definitely wonder how two places with such a big temperature difference can belong to the same empire.

"Although this place is not far from the Holy Altar, there is a big difference in temperature!"

The last time he and Luo Ruoxi came to the canonization platform, it was not too far from here, it was only a few hundred kilometers, such a close distance, the climate there was very normal, and there was no burning here at all, "The canonization platform, heaven and earth canonized, with the blessing of saints, the natural wind and rain are smooth, and here, there are several huge active volcanoes, and the heat is inevitable!"

The carpenter explained.

Zhang Hang nodded.

He had a map of the Hongyuan Empire in his mind, and he knew the situation here.

Fire Source City, known as the "Fire Source", the source of fire...... You don't have to think about it to know that the temperature is unacceptable.

"If it's so hot here, why build a city and stay here with so many people?" Luo Ruoxi couldn't help but ask.

With so many active volcanoes erupting at any moment, and it's so hot, why are there still people who don't leave?

"Huh!"

Before the carpenter could answer, Zhang Xuan smiled: "Although it is hot here, it is very suitable for growing some medicinal herbs that like to be dry, for example, withered leaf grass! This medicine can grow without water, and during the growth process, the leaves are always like dead and get its name! A withered leaf grass, once sold, can be sold for the price of a high-grade spirit stone." ”

"So expensive?" Luo Ruoxi was stunned.

For ordinary people, a high-grade spirit stone is enough to eat and drink for a lifetime, and it can't be used up.

With this kind of price for a medicinal herb, it is no wonder that countless people are eager to stay in this kind of place.

"Not only that, but there are also some special holy beasts and spirit beasts here, each of which is very rare, and it is worth a lot of money if you sell it...... Moreover, it is also a treasure land for mineral deposits!" Zhang Xuan continued.

After reading all the books of the Famous Teachers Academy, I know more about the situation of the Hongyuan Empire than many native-born famous teachers.

"I see......" Luo Ruoxi understood.

There must be a reason why people can stay here, or even build such a huge city.

"Hehe, Uncle Shi is really knowledgeable!"

Hearing his introduction, the carpenter glanced at him with praise.

My uncle, although he is a little unreliable, but the amount of knowledge in his mind is real, whether it is human geography or special professions, it is easy to come by, which makes people have to be convinced.

Because of this, Hongyuan Academy, a huge concentration of famous teachers that has been inherited for thousands of years, chose him to be at the helm.

"Say it, it's nothing!" Zhang Xuan smiled.

"There is still some time before the seal is opened, I think it is better for us to go to the Hall of Famous Teachers and gather with everyone first!"

While the three of them were talking, the holy beast had already come to the sky above the city, slowly descended, and soon came to a majestic and towering hall.

Famous Teacher's Hall!

This city is much larger than Jingyuan City, and the population is more dense, with a branch of the Famous Teacher's Hall, but the strongest hall master is only in the middle of the first level of the Holy Domain, which is far from Hongyuan City.

"I've seen the woodmaster!"

As soon as he walked in, a middle-aged man greeted him.

"Well, where are the Han Xu Array Mage and Wu Shi and the others, take us over!" the Wood Master smiled.

"Master Wu, they have already ...... two days ago Went to Yanlin Mountain!"

The middle-aged man hurriedly replied.

"Went to Yanlin Mountain?" The wood master was stunned: "Isn't there still a few days before the seal can be opened?

"I don't know, just let me stay here and receive other famous teachers who have arrived, so that they must pass as soon as possible!" said the middle-aged man.

"Got it!"

Nodding, Master Mu didn't ask any more questions, and looked over: "Since Master Wu and Master Han Xu have passed, I'm afraid that the changes in the seal are more serious than I knew before, let's go over and take a look!"

"Hmm!"

Zhang Hang and the others nodded, and sat on the back of the flying holy beast again.

"The place where the seal is located is not in the city, but in the depths of the Yanlin Mountain Range, more than three hundred kilometers away from here, there is a huge active volcano, which is very hot and has always been inaccessible to people......

Standing in the room on the back of the beast, the carpenter explained the situation of the seal in detail.

The place where the seal was established, like the island where the poison temple is located, is an active volcano, and the huge formation is maintained by the power released from the volcano.

Therefore, before the seal is opened, even if there are countless masters of the Famous Master Hall, they don't dare to come hard, so they can only wait here.

The distance of three hundred kilometers is not too far, and in less than ten minutes, I saw a tall mountain peak appear in front of me, thousands of meters high, majestic, but the top was bare, there was no vegetation, almost all of them were fiery red stones, and before they came to them, they gave people a feeling of burning skin.

"This is the Qinghuo Pill! If you take it, you can counteract the effects of the fire poison and not be harmed!"

With a flick of his wrist, the carpenter took out two pills and handed them over.

Although their strength, this level of heat is nothing, but after staying for a long time, there will still be fire poison invading the body, leaving symptoms.

In order to prevent this situation, half a month ago, the new Dean Zhou of the Alchemy Master Academy had many students refine enough Qinghuo Pill.

This kind of elixir can be refined by a four-star alchemist, it is not complicated, and it is condensed by using some medicinal materials that clear heat and detoxify, and it has a good effect on eliminating fire poison.

"Thank you!"

For Zhang Hang, he has the true qi of the Heavenly Dao in his body, and he is not even afraid of poison, so he is naturally not afraid of these fire poisons, but the other party has some kind intentions, and he can't bear to refuse, so he takes it casually and swallows it with his mouth open.

When the pill entered his throat, he suddenly felt a cool feeling pouring into his whole body, and the scorching heat he felt before seemed to be gone.

"It's not ...... Ordinary Qinghuo Pill?"

Although there is no difference in appearance, the nature of this elixir is obviously much more powerful than ordinary ones.

"I collected a lot of medicinal herbs and ......refined them myself," the carpenter smiled.

"No wonder!" Zhang Hang nodded.

He is a seven-star famous teacher, and there is an alchemist in the minor profession, and he refines the fourth-level elixir, and the effect is naturally extraordinary.

The holy beast flew, not for a long time, came to the top of Yanlin Mountain, looked down, and saw a huge circular pit in front of it, no math student, sitting cross-legged around, constantly instilling true qi in a certain place, sweat on his head.

"They're ...... Seal Firmly"

The carpenter's face sank.

It seems that the seal is indeed more dangerous than they imagined, otherwise, it would not be possible for so many people to do it together.

"It should be the dean of the Formation Law Academy, and the 10,000 students brought ......"

After a glance, Zhang Xuan nodded.

These are all students of the Famous Teachers Academy, wearing special clothes, which can be seen at a glance.

Whew!

Just as he felt that these students couldn't hold on, he saw another group of students come to him, their palms flying, and the formation flags that had just been successfully refined were placed in fixed positions.

These positions, while not changing the structure of the seal, do make it stable.

It was the many students of the Alchemist Academy.

The students of the two faculties work together seamlessly, and their movements are fast and fluid, and it seems that they are doing this a lot these days.

Seeing so many students, working hard to stabilize it, the round pit below had a feeling that it would explode at any time, Zhang Hang frowned, the texture in his eyes flashed, and he looked straight down.

"What a cumbersome formation......"

glanced at it, and eyebrows jumped.

The understanding of the formation is not weaker than that of the Seven Star Array mage, but looking at the prohibition below, it is still a little dizzy and difficult to understand.

"It's not like ......"

The more I looked, the more confused I became.

It looks like a formation, but it's not quite like it.

Although this seal is a little unstable, it has not been activated, so it cannot be judged by the Heavenly Dao Library, and if he relies on the Eye of Reason alone, with his current knowledge, if he wants to figure it out, it will not take a few months, and he will not be able to do it.

If it's really a formation, don't think about it, it's definitely more than level seven!

A large array of more than seven levels...... No wonder there are so many famous teachers in the Qingyuan Empire's Famous Teachers Hall who don't dare to act rashly.

It's beyond what they can handle.

Whew!

He observed here, and the wood master on one side controlled the holy beast to fly down slowly.

fell to the ground, and before he came to the round pit, he saw Wu Shi coming over: "Master Zhang, Master Luo, Master Mu, you are here!"
