After a conversation with Dan Vo, Chu Nan also had some ideas for the breakthrough of Dan in the future.

Of course, the specific situation still needs to be made after Chu Nan reaches the Jiedan realm before he can have a more detailed plan.

At present, he is still only a fake Dan realm after all.

After some communication with Danh Vo, both of them had a good harvest.

Although Dan Vo failed to get a way to improve the success rate of alchemy from Chu Nan, Chu Nan's views on alchemy gave him a lot of inspiration.

Even if he can't have the same alchemy success rate as Chu Nan here, it can also make him have a great improvement in the success rate of alchemy.

In the next few days.

Chu Nandu stayed in this city, while alchemy, he would discuss the understanding of alchemy with Dan Vo and Mu Shixuan in his free time.

Benefit a lot.

And with Chu Nan's success rate in alchemy, in just a few days, he had successfully refined many elixirs, more than all the demons here combined.

His military exploits have also reached a terrifying number.

After Chu Nan felt that it was about the same, he found the person in charge of the Fu clan here and told the other party that he wanted to go to the front line.

The person in charge of the Fu clan here is an old man in the realm of heaven and earth, and he attaches great importance to these demonic alchemists sent by the Fu clan this time.

After learning Chu Nan's idea, he rejected it in one go.

These demonic alchemists......

For the Fu clan, it is very important, even if the Fu clan let them participate in the war, they will arrange them to do alchemy support in the rear, and they don't want them to enter the front line to take risks.

After all, in the eyes of ordinary people......

The alchemist's frontal combat ability is very weak, and if he ventures into battle, there will inevitably be a crisis.

It is safest to stay behind to provide support.

However, Chu Nan was not an ordinary alchemist here, he informed the other party that he had the strength to fight in the late stage of the Dan Realm, and he had more than enough self-preservation.

The person in charge of the Fu clan hesitated.

For Chu Nan here......

He'd heard about it, but the stakes were so high that it was hard for him to decide.

Ultimately.

He transmitted the message to Fu Sisu, the ancestor of the Fu family, and asked the other party for instructions.

Fu Sisu agreed.

He knew more about Chu Nan and knew that with Chu Nan's ability, it was more than enough to save his life on the battlefield.

That day.

The person in charge of the Fu clan here made arrangements and mobilized a warship to carry Chu Nan to the front line of the battlefield.

Originally, Mu Shixuan also intended to go with Chu Nan, but Chu Nan still let her stay behind.

After all, the battle situation ahead was urgent, and Chu Nan felt that Mu Shixuan could stay in the rear to support, and there was no need to follow him to the front line.

On the same day, Chu Nan took a warship and went to the front line of the battlefield.

Soon after.

In the distance, on the horizon, as the early sun rises, a mountain-like wall appears.

The moment he saw this city wall, Chu Nan's heart was shaken, and the city wall in front of him ......

It's like a giant dragon lying there, winding away, spreading for an unknown distance.

Everything you can see is the city wall......

At the same time, the entire city wall was nearly a thousand zhang high, and there was a huge white light film that seemed to be connected with the sky, which also rose from this city wall, forming a seal!

From a distance, the city wall merges with the light film, like a barrier!

Although the entire city wall was built only recently, the color of the city wall has changed from black to dark red......

Even now, looking at it from a distance, Chu Nan can feel a stream of blood coming from the city wall, it can be imagined that in this war, the city wall has been stained with countless blood, including the blood of demons, and the blood of the cultivators of the three major alliances.

As far as the eye can see, the surroundings are desolate, and at the same time, there is no grass, and an indescribable slaughter is condensing from the city wall, which seems to affect the firmament, so that above the firmament, the clouds are surging, forming a terrible whirlpool, which is constantly turning, making a loud rumbling sound.

There were red lightning bolts, swimming in the whirlpool, sometimes crossing the sky, as if red dragons were flying and roaring.

The dark red city wall, the white light film, and the runes and formations laid out in every brick and tile on the city wall form the current Chiyue Alliance, blocking the invasion of foreign enemies...... The ultimate defense!

Even here, it can be clearly seen that on the city wall, there are countless more war weapons than the city behind.

These weapons used in war all looked extremely hideous and full of terrifying lethality, and now Chu Nan had witnessed an earth-shattering attack from one of the war weapons.

Everything in front of him was something Chu Nan had never seen before, and it brought him a great shock.

Especially those war weapons, the power under their outbreak can even destroy the Great Perfection of the Jiedan Realm!

Even in the Heaven and Earth Realm, if you are hit head-on by this kind of war weapon, even if you don't die, you will be seriously injured.

As it approaches.

Chu Nan found that behind the city wall, there was also a city, this city was extremely huge, even bigger than the city behind earlier, countless breaths were condensed in this city, and there were many knots in it, even if it was a strong person in the Heaven and Earth Realm, there were nearly a hundred!

It's a pity......

There is no Domain Slashing Realm powerhouse in charge.

At the same time, in this city, there is a towering tower, this tower is thousands of meters high, standing in the city, so that inside and outside the city wall, can be clearly seen, there is a light shining in the tower, the light is bright, every turn, it seems to be able to make the void shake.

Especially at the top of the tower, there is a huge bead inlaid with a huge bead, which is a hundred zhang in size, and it is turbid inside, as if there is a mist swimming away, and sometimes after condensing, it will form a vague figure.

But anyone who is stared at by this vague figure will tremble.

The tower......

It is also a treasure shared by the three major alliance clans in the Chiyue Alliance Land!

Akagaku Tower!

Legend has it that the last powerhouse of the Chiyue Alliance, in order to prevent the Chiyue Alliance from being invaded by foreign enemies in the future, sealed his soul into the beads on the top of the Chiyue Tower!

Nowadays, there is only this Akagake Pagoda in the Akagake Alliance......

can barely compete with the powerhouses of the Slashing Realm.

It's just that the demons outside the Chiyue Alliance are far more than a slashing realm.

If you wait for those demons of the Domain Cutting Realm to invade on a large scale, the entire Chiyue Alliance will definitely be ruined and difficult to resist.

The people of the three major alliances are very aware of this, so they are now desperately trying to block these invading demons and prevent the expansion of the barrier.

If those Domain-Cutting Realm demons can't enter, they still have some chance of winning, but once those Domain-Cutting Realm demons are killed, they won't have any chance of winning.

As the warship kept getting closer.

The battle situation outside the city wall was also vaguely seen by Chu Nan.

In front of the city wall, there was an incomparable barrier, but now the barrier was partially broken, causing the demons from the outside world to continue to kill like locusts crossing the border.

However, the distance is too far away, and I can only see a rough idea, which is not particularly clear.

After about a stick of incense, the ship finally reached the castle behind the city walls.

The city here is much larger, and the division of the area is also very clear.

The three major alliance clans also have their own territories here, and after the arrival of the warship, they directly entered the territory of the Fu clan.

The atmosphere here is as heavy as the city from before, if not heavier.

At the same time, there are also alchemists and refiners here.

It's just that the reason why the Fu clan didn't send these demons of Chu Nan to this city was mainly because they were worried about the safety of these demons.

After all, this city is not peaceful, there are war weapons on the side of the Chiyue Alliance, and those invading demons will also use war weapons to cross the city wall and directly attack the city behind the city wall.

And these invading demons all have some special and strange means.

This is a great threat to alchemists, so the real elite alchemists generally stay in the rear and will not be sent to the front line.

As soon as Chu Nan arrived, there were Fu clansmen who sent Chu Nan a battle armor unique to this place.

This kind of armor is very extraordinary, and there is a powerful energy in the armor.

The Fu clan told Chu Nan with a serious face that the energy in this battle armor was mainly used to resist those strange means of demons.

For example, not long ago, those demons used strange methods to make the sky of this city rain black......

This kind of black rain is not ordinary rain, when the black rain falls on the cultivator, it will actually cause the aura in the cultivator's body to corrode.

Similar methods, during this time, these demons are often cast.

As for the three major alliances, they can only resist with this special armor now, but the effect is not good.

This is also a difficult problem faced by the three major alliances at present.

"Black Rain ...... Corroding Aura"

Chu Nan thought thoughtfully.

That's when it happened.

Woo!

And suddenly the wind rose in the midst of the city.

"Not good!"

The Fu clan was shocked, and immediately activated the energy in the battle armor, and asked Chu Nan to quickly activate it as well.

This sudden wind is obviously not a natural wind......

This is a method similar to the Black Rain used by those demons.

Call!

This gust of wind seems to be the same as a normal wind, but it actually contains corrosive power, but what corrodes is not aura, but ...... Flesh!

Chu Nan saw.

Although some people not far away activated the energy in the warframe, the energy in the warframe could not completely resist this corrosive force.

Only partially weakened corrosive power.

Thereupon......

Some cultivators who couldn't resist the corrosive power suddenly withered their physical bodies at a speed visible to the naked eye.

In an instant, most of the flesh and blood had dissipated, which was very terrifying.

"Hey......"

The Fu clansmen in front of Chu Nan sighed at this.

The demons outside the Chiyue Alliance have many means, and these methods have never appeared in the Chiyue Alliance.

I don't know how to resolve it.

It can only be weakened to a certain extent, but the weakening alone will still make some cultivators unbearable.

And although Chu Nan activated the energy in the battle armor here, he also felt the corrosive power contained in the wind, of course, in terms of his physical strength, such corrosive power would naturally not have any effect on him.

Chu Nan carefully felt this corrosive force.

Eyes flashed.

He felt ......

Maybe here, there is a chance to be able to resolve it!

This corrosive wind is still continuing, which is also one of the reasons why the Fu clan does not allow elite alchemists to come over.

Even the Sioux did not let their elite refiners arrive.

Every few days, a similar approach is presented.

In the absence of a complete resolution, everyone in the city will be affected.

This is also a hidden danger that the three major alliances are currently facing, although there is a reduction in the energy in the battle armor, but it will still have an impact, some spiritual cultivators may be able to resist in a short time, but over time, they will gradually be corroded.

After Chu Nan arrived.

There was no rush to find Dong Yuchen.

This city is very large, it is not easy to find someone here, and at the same time, Dong Yuchen may be in the battlefield now, and he is not in the city.

Chu Nan felt ......

It's best to let Dong Yuchen come to him.

And if you want Dong Yuchen to know that you are here, you need to have a certain reputation in this city, so that most people know about you.

Although Chu Nan now has a certain reputation among the Fu clan, it is not enough to let most people know about him in the Chiyue Alliance.

Now, there's a great opportunity!

Chu Nan felt that as long as he could solve this corrosive wind, as well as the other methods of those demons, he would naturally be able to attract everyone's attention in this city.

Thereupon.

On the day of his arrival, Chu Nan began alchemy.

He wanted to refine a pill that could dissolve this corrosive power.

Earlier, when he felt this corrosive power, he already had some clues, and now he was alchemy according to his inner thoughts.

On the second day......

His elixir has been refined.

"Try it. ”

Chu Nan found a Fu clansman who was contaminated with corrosive power and asked him to take the elixir he had just refined.

Call!

Suddenly.

The corrosive power on this Fu clan quickly dissipated.

Chu Nan's eyes lit up.

He did it.

The elixir he refined was able to restrain this corrosive power to a great extent and dissolve it.

Thereupon.

Chu Nan took the initiative to contact Fu Sisu, the ancestor of the Fu clan, and told him about it.

Chu Nan was going to teach the refining method of this elixir to the alchemists here and let them refine it together.

After all, there are a lot of people here.

If it was just Chu Nan who came to refine the pill alone, it would obviously not be enough......

When Fu Sisu, the ancestor of the Fu family, learned the news, the whole person felt very surprised.

The problem of corrosion has always been a big hidden danger for everyone here, and it has never been solved.

Now Chu Nan said here that he could refine the elixir that solved the power of corrosion.

This made Fu Sisu overjoyed.

That day.

He came to see Chu Nan in person.

Chu Nan handed the elixir in his hand to Fu Sisu, and after Fu Sisu took it, he looked at it carefully, and his eyes gradually bloomed.

With his vision, there was no need to find someone to try, just at a glance, he could see that this elixir could indeed restrain and dissolve the power of corrosion.

Fu Sisu's face was full of excitement and appreciation.

"Very good, Fu Shuang, I really didn't misunderstand you!"

At the beginning, after he learned about Chu Nan's terrifying talent in alchemy, he already felt that Chu Nan would definitely have extraordinary achievements in alchemy in the future.

Sure enough.

Now that Chu Nan had just come to this city, he had directly refined an elixir that could dissolve this corrosive power.

Prior to this, the people of the Chiyue Alliance had been unable to do anything about this corrosive power.

Now it can finally be resolved.

That day.

Fu Sisu summoned most of the alchemists in the city and asked them to learn the refining of this elixir from Chu Nan.

Many alchemists were shocked after hearing that Chu Nan could refine the elixir that dissolves the power of corrosion here.

During this time, they had been researching the elixir that dissolved the power of corrosion, but no matter how they studied and discussed, they couldn't think of how to refine such an elixir.

I didn't expect ......

Chu Nan had just arrived here, and he had directly refined an elixir that could dissolve the power of corrosion.

Then when these alchemists heard that Chu Nan was the demon alchemist of the Fu clan, they were relieved one by one.

Among them, there are not only alchemists of the Fu clan, but also alchemists of the Lin and Su clans.

I have long heard of the demon alchemists of the Fu clan and know the horror of these demon alchemists.

Now they all followed Chu Nan and began to learn the refining of this elixir.

Fortunately, the refining method of this elixir is not difficult, and at the same time, it is not refined by the alchemy of the Fu family, there is no problem of success rate, as long as you master it, you can refine it.

Soon, these alchemists mastered the refining method of this elixir.

Thereupon......

Many alchemists have begun to refine such elixirs.

At the same time, Fu Shuang's name also spread throughout the city for the first time, so that everyone in the city clearly knew the existence of this demonic alchemist among the Fu clan.

For a time, Chu Nan's reputation completely rose in the city.

Countless people were full of gratitude to him here, if it weren't for Chu Nan refining the elixir that dissolved the power of corrosion, many of them would still be tormented by the power of corrosion.

Now......

Finally, there is no need to be afraid.

Although Chu Nan's elixir dissolved the corrosive power here, the three major alliances still did not let their elite alchemists and refiners come.

After all, there are likely to be other crises in the future.

It's more conservative to let them stay in the rear.

This time, Chu Nan successfully refined the elixir of dissolving the power of corrosion, allowing him to obtain a lot of combat exploits at one time.

At the same time, many spiritual cultivators in the city came to visit Chu Nan to show their gratitude to Chu Nan.

However, Chu Nan did not wait for Dong Yuchen's arrival.

It made him frown.

Now everyone who stays in the city already knows about his existence, and if Dong Yuchen is also in the city, he will definitely come to him as soon as possible.

But he waited for several days, and he didn't see Dong Yuchen coming, so there were only two possibilities left.

One is that Dong Yuchen is currently on the city wall and battlefield in front of him.

The other is that Dong Yuchen did not come here.

After thinking about it for a while, Chu Nan decided to go to the city wall first to look for it.

If Dong Yuchen can't be found on the city wall and the battlefield, then there is a chance that Dong Yuchen is not here.

Chu Nan felt ......

With Dong Yuchen's mind, even if he thought he was going to join the Su tribe and went to the Su tribe, and he didn't see himself in the Su tribe, he should have guessed that he was joining the Fu tribe.

However, after so long, there is no news of Dong Yuchen.

"Could it be that Dong Yuchen has encountered any danger?"

Chu Nan frowned.

For now, he can only look for the walls and battlefields before he can make a judgment.

Thereupon.

Chu Nan contacted Fu Sisu, the ancestor of the Fu clan, and told him that he wanted to go to the battlefield.

However, this time Fu Sisu refused.

He said that letting Chu Nan come to the city is already the biggest concession, and he will never let Chu Nan go to the battlefield, it is too dangerous there.

In fact, after Chu Nan refined the elixir that dissolves the power of corrosion, on the Lin Clan's side, some people proposed to let Chu Nan go to the battlefield.

They felt that with Chu Nan's talent in alchemy, he might be able to solve some problems on the battlefield.

After all, those demonic methods are not only used here in the city, but also on the battlefield, more commonly.

They felt that if Chu Nan could also resolve the problems on the battlefield, then they would be much easier.

But Fu Sisu directly refused here.

He said that he would not let Chu Nan take this risk.

Even if Chu Nan already has the strength to fight in the late stage of the Dan Realm, there will also be a crisis.

Fu Sisu told Chu Nan that in the Chiyue Alliance, not everyone was bent on fighting against foreign enemies, and some people had secretly surrendered due to the oppression brought by those foreign enemy forces.

This has led to a lot of information in the Chiyue Alliance being leaked to the demons in advance, such as Chu Nan's refining of the power elixir to dissolve corrosion, and those demons already know about it.

They will inevitably target Chu Nan for this and try to assassinate Chu Nan.

Therefore, Chu Nan must not leave the city now.

Even on the city walls, there will be crises.

Chu Nan couldn't help frowning.

He was desperate to find Dong Yuchen now, and if he didn't go to the city wall and the battlefield, it would be difficult to find it.

And he couldn't ask anyone else to help him find it.

After all, he didn't know what kind of appearance and identity Dong Yuchen was now......

"I really need to go to the city walls. ”

Chu Nan said seriously.

Fu Sisu also realized that Chu Nan had a reason why he had to go to the city wall, and after some thought, he finally nodded and agreed.

"Yes, but you'll have to wait a few more days, and then I'll come with you!"

Fu Sisu felt that with him by his side, there was no problem in protecting Chu Nan.

At this stage, the city wall is quite safe, but Fu Sisu is worried that those demons will come up with some strange methods from time to time.

After all, the Chiyue Alliance Land was isolated by the barrier, and they had not been in contact with the outside world for too long, resulting in many methods from the outside world, and they were extremely unsuitable.
