Lu Cheng finally understood that the Demon Realm would attack in advance.

He is a smart man, if he is not smart, he can't be a master, in the face of the invasion of the demon army, he is methodical, step by step to issue the most effective orders, so that the huge machine of Shushan can run quickly and prepare for war.

At this moment, he completely showed the demeanor of a master, it can be said that he is doing a good job, and only he can control all this.

Emperor Hua was one of the fifteen emperors who had been trapped before, and he had been worried for a long time when he received the news from White Emperor City before, and he also understood what it meant for the fifteen emperors to be trapped.

Fortunately, the news came to Shushan in advance, if they waited for the Demon Realm to break through the critical point, they would learn the news, it would be really late, and it was really possible that Shushan would not be able to be saved and broken by the Demon Realm.

Now they got the news in advance and made arrangements in advance, and Vantage, who was trapped and couldn't get out, appeared again, and provided him with the latest news, although it was only a safe news, but he was smart enough to guess a rough idea.

The conspiracy of the Demon Realm has been broken, the Fifteen Emperors are not really trapped, they are now out of trouble, as long as they come out, the possibility of chaos in the Immortal Realm will no longer exist, and they will also come to Shushan to fight against the invasion of the Demon Realm together.

No wonder the Demon Realm would suddenly attack ahead of schedule, they must have also gotten the news, so they deliberately did so.

I have to say that Lu Cheng is really smart, he guessed most of them correctly, Emperor Hua is the one who has comprehended the origin of the power of wind and the origin of space and the origin of the power of thunder, he is the fastest, he is the first immortal emperor to return to the city, and he is also the first person to pass the news back.

Their escape from the predicament is definitely the best news for Lu Cheng, which is also the reason why he laughed a lot, and it was definitely the most favorable news that he could let him release a big smile in the early stage of the war.

The Qingshi Immortal Emperor was just stunned for a moment, and then laughed as well, the other Immortal Emperors were all the same.

"What's so happy smiling?"

A person suddenly walked in outside, he was the Guan Guang Immortal Emperor of Huodi City, and he was also one of the Immortal Emperors who came to support, and he was also the first Immortal Emperor to come here.

"Vantage has returned to Vantage City, do you think it's worth being happy?"

Lu Cheng smiled and nodded, Guan Guang was stunned for a moment, and soon laughed as well.

"A good thing, an absolute good thing, worth having fun with!"

Emperor Guan Guang Immortal laughed with them, before he knew that the fifteenth emperor of the Dao was also quite depressed after being trapped, there was the orthodoxy of their Huo Di City, and now he was naturally happy to hear that they were out of trouble.

This also shows that this conspiracy of the Demon Realm has failed.

"The emperors are out of trouble, I believe that this time my immortal realm will definitely win, let the demon cultivators go back in disgrace, never dare to come again, and can also win more than 100,000 years of stable time for my immortal realm again!"

Lu Cheng said loudly, it takes a long time to prepare for a demon realm invasion, and once it is launched, it is impossible to retreat, although the loss in this battle will be not small, but they are the defenders, and they have more advantages than the attacking demon realm side.

As long as they can't break through the defense line of Shushan, the battle situation will be stalemate here, which is the most beneficial for them, and after killing and injuring a large number of people in the Demon Realm, they will not be able to recover in a short time.

In fact, the demon world can also retreat halfway, but it's a pity that once they start a war, they must not retreat halfway, not to mention the decline in morale after retreating, it is not possible to start such a war again, and the most important thing is that they will appear very incompetent, which will make people in the demon world think that they are inferior to the fairy world, and they will think that the current demon emperor is not as good as the previous demon emperor.

After these few attacks on the fairy world failed to break through Shu Mountain, the Demon World has already produced some such thoughts, which is also something that the Demon Emperors cannot accept, even if they fight to the end, they will continue until they break through Shu Mountain.

This is what the fairy world is willing to see, and they use the front line of Shushan to directly fight the demon world.

However, this is not absolute, not without danger, once the Shushan front line collapses, the disaster will definitely be huge, because most of the strength of the fairy world is concentrated here, and the follow-up defense will inevitably weaken, and when the demon world really enters the fairy world, it will be equivalent to destruction for the fairy world.

"That Demon Emperor trapped them and let them break through in such a short time, it seems that it is just average!"

Emperor Guan Guangxian said with a smile, Lu Cheng and Qingshi also had smiles, but they were much lighter.

It's a good thing that Vantage and Huo Di are out of trouble, but the crisis has not been resolved, they can laugh at the demon cultivation here, or say that the demon cultivation is all kinds of bad, but they must not really despise them.

They really despise the Demon Cultivator, thinking that if the Demon Cultivator is nothing more than that, then they must be the ones who are unlucky in the end, and they will pay a terrible price for it.

……

The critical point opened, and Yang Gutian personally led the vanguard army into the immortal realm, and the moment he stepped into the immortal realm, he also raised his head and took a heavy breath of the air of the immortal realm.

He didn't like the immortal power of the fairy realm very much, and he didn't like it the last time he came, but the resources here were what they needed, and the resources here were more sufficient than the demon realm to make them extremely red-eyed.

"Immortal Realm, I'm back again, Liu Yiyang, this time I will definitely kill you and get back the artifact!"

Yang Gutian said to himself, this is the second time he has come to the Immortal Realm, and the first time he came, he was still the Demon Lord, the first Demon Lord of the Demon Realm.

The interval between the two was short, but this time he was already a Demon Emperor.

The other Demon Emperors came to the Immortal Realm for the first time, and they were all curious about this place, they had been discussing the Immortal Realm for a long time, and they had discussed it for a long time, but it was the first time they really set foot on this land.

The 30,000 pioneer battalion was the most excited, many of them were also very repulsed by the immortal power of the immortal realm, but entering the immortal realm was a great thing, entering the immortal realm they were victorious, and they finally hit the enemy's territory.

The vanguard battalion did not advance quickly, they had to maintain a neat formation, and to maintain their position, the marching speed had to be a little slower.

But it was only a little slower, as all the pioneer battalions entered the immortal realm, the follow-up vanguard army demon realm army also entered the immortal realm one after another, entering this place where they had never been before, but they were destined to fight.

"Your Majesty the Devouring Emperor, the front is blocked by immortals, and the vanguard camp is already at war with the other party!"

A golden demon quickly came to report, in fact, he didn't need to say that Yang Gutian himself had already seen that they had encountered the first blocking location in the immortal realm ahead.

This is just an ordinary blocking point, with a large defensive formation, this formation is good, Yang Gutian has already seen that this is the arrangement of the Immortal Emperor, and there is more than one Immortal Emperor who has arranged the formation.

There are also a lot of immortal cannons in it, which is a relatively large defensive immortal weapon, the level of the immortal weapon is not high, only intermediate, but because it can release a powerful immortal attack, it can have a wide range of lethality, and is widely used by immortals.

The most used is naturally the Shushan side, this kind of immortal cannon can send out twenty immortal attacks at a time, each attack can reach the full force of the late stage of the Golden Immortal, such an attack can not be resisted all the time even if the Demon Lord encounters it, and the Golden Devil will be injured if he can't take a few hits.

The biggest advantage of this kind of immortal cannon is that as long as there is enough immortal power, it can be fired, and the immortal power can be provided with immortal stones, that is, if there are enough immortal stones, even the immortals can also control such immortal cannons to kill and injure the enemy.

There are not many immortals in this defensive position, only a thousand people, but there are fifty immortal cannons of this kind, and the fifty immortal cannons soon let out a roar, and one after another white immortal attacks continue to shoot towards the demon realm pioneer camp on the opposite side, and some unintentional golden demons have been hit and injured.

"Array, shield!"

The commander of the pioneer battalion quickly stabilized his position, and a number of magic shields were erected in front of the long line, there were two thousand of these shields, which could effectively block the attack of the immortal cannons.

There was no chaos in the pioneer camp, Yang Gutian nodded slightly, after the shield was erected, the threat of the immortal cannon to them was reduced a lot, these shields were very strong in defense, only the immortal cannon with the attack power of the late stage of the Golden Immortal could not break its defense.

After the shield, the vanguard battalion of a thousand demon lords and many golden demons also began a counterattack.

The powerful defensive formation appeared, helping the immortals inside to resist the attacks of external enemies, and various energy light clusters were flying in the air, while the immortals within the formation were trying to divert the muzzles of the cannons and try to hit those demon cultivators who were not protected by shields.

Two thousand shields could not protect the pioneer battalion of 30,000 people.

Their transformation still had a certain effect, but as the vanguard battalion formation stabilized, they also activated the protective formation, and the role of the immortal cannon was already limited, and both sides were attacking.

Yang Gutian had been standing behind, watching with the eleven Demon Emperors.

This formation is very powerful, but he and the eleven Demon Emperors will shoot together, it won't take long to break through, and the thousands of immortals inside will definitely be torn apart by the vanguard camp of 30,000 people, and the current pioneer camp is like a tiger out of the cage, no matter who can't stop their claws and sharp teeth.

However, Yang Gutian didn't do this, if everything depended on their Demon Emperor, then why should they take them, just let the Demon Emperor come to fight, and there was no need to start any big war at all.

This in itself is a full-scale war between the two realms, and no one who comes here can escape, so letting the vanguard battalion attack on its own, and letting them lay this line of defense first, can also give them confidence and play their might.

"Order, if you can't break through the small defense line in front within half an hour, this emperor will change the vanguard second regiment to attack!"

Yang Gutian suddenly commanded, the demon cultivators also needed to be motivated, and sure enough, after this order was passed over, the offensive of the pioneer camp became even more fierce, and even some golden demons went up despite being injured.

In less than half an hour, the protective formation arranged by the Immortal Emperor was broken, and the thousands of immortals inside quickly retreated, but it was a pity that hundreds of demon lords in the pioneer camp attacked together, and less than twenty people finally fled back.

The first line of defense was breached by the Demon Realm, and it took less than half an hour.

This result was quickly brought to Lu Cheng, who frowned and did not speak.

His requirement was to hold for an hour, but the final result was that half of it was not reached, and he believed that his disciples had done their best, but they still did not complete the task, which could only show that the other party was too strong.

In half an hour, the other party broke through a line of defense, this time the demon cultivator was coming very fiercely, and he was not completely ready now.

"Brother Guan, Brother Fang, Brother He, Brother Shao, can you please bring some people to the front to assist in the defense, we need two and a half hours!"

Lu Cheng turned around and said to the four people standing there, these four people are all Immortal Emperors, and they are all Immortal Emperors who have arrived here one after another to support Shushan.

The coming momentum of the demon cultivator is too fierce, they are not well prepared, once this line of defense is broken, the next line of defense will not last long, at present, there are only three lines of defense before Shushan, and breaking through these three lines of defense is the Shushan Great Array, and Shushan will directly face the demon cultivator.

Shu Shan is not afraid of demon cultivation, but he needs sufficient preparation time, he still needs at least two and a half hours, and now he can only invite the Immortal Emperor to come forward and let the Immortal Emperor go to the front of a defensive line to assist in the defense, so as to provide him with enough time.
