Ancient Battlefield.
Lu Changsheng, Mr. Shi, and Shi Sheng arrived here.
The moment the Immortal Emperor saw the Master, he couldn't help but bow his head respectfully and say, "Master."
The man nodded slightly and smiled, "Thank you for your assistance from the Immortal Realm."
In terms of seniority, the Master was higher than the Immortal Emperor. At that time, the Master taught several Human Ancestor and countless God Emperor, including the Immortal Emperor, who also received some of the Master's teachings.
After exchanging pleasantries, the Immortal Emperor immediately said, "The initial defensive measures are now complete."
Upon hearing this, Lu Changsheng and his teacher looked in the direction the Immortal Emperor had pointed.
As far as the eye could see, towering mountains rose into the sky! These continuous mountains were further reinforced by array formations.
This is the first line of defense, a high mountain formed by the combined efforts of the Immortal Emperor and the top experts of the Immortal Realm, who used the Power of Rules heaven and Immortal Realm!
When the Evil Devil Domain descends, one must traverse high mountains and navigate through arrays. As for flying? Without absolute strength, it is probably impossible to fly through an array that prohibits air movement.
Beyond the mountains lay a vast plain, devoid of any pits or obstacles.
After passing through the vast plains, there were those towering and thick city walls!
Between the city walls, every fifty miles there is a tall tower. According to the Immortal Emperor, there are talisman masters skilled in talisman making on these towers who can use talismans to launch long-range area-of-effect attacks or attack the air.
"The major powers in the Mortal Realm have also set up strongholds in the rear," the Immortal Emperor said with a smile.
With the help of the Divine Lord Hao Tian and the Immortal Emperor, the world was informed that the Evil Devil Domain was about to sweep across. After a period of panic, more forces chose to go to the Ancient Battlefield. After all, this was not a matter for one person alone. If the Evil Devil Domain broke through the defenses, the entire Mortal Realm, including their own forces, would be destroyed!
Even if it's not for the sake of all living beings, it's for your own sake.
However, without a figure like the Immortal Emperor, it's likely that not many people would believe the Divine Lord Hao Tian on his own.
Then, the Immortal Emperor said, "However, the formation still needs your refinement."
As she spoke, she looked at Lu Changsheng.
Lu Changsheng nodded, but after thinking about what the old man had told him, he realized that the power of the formation should not be too great. Before figuring out the forces behind it, Lu Changsheng felt it was better to be cautious.
However, there is still room for maneuver in terms of defense, at least enough to make the Evil Devil Domain's attack less effective.
For example, the anti-flight formation brought by the Immortal Emperor might be okay, but after Lu Changsheng strengthened it by a little bit, well... the other side will probably have to cross the mountain on foot.
For example, there are sturdy formations on the city walls, and formations on the city walls that can restore injuries and replenish Immortal Qi.
In less than half a day, Lu Changsheng had completed all the arrangements.
Then, they took out huge cannons from the city wall.
"What is this?" the Immortal Emperor inquired.
"Artillery," Lu Changsheng replied.
Indeed, after learning about the composition of the enemy's army, Lu Changsheng believed that the cooperation between the Evil Devil Domain's armies largely depended on the restraint of these two air forces.
Of course, this is on the premise that high-level combat forces have not been deployed.
However, Lu Changsheng has already set up an anti-air formation here. With the strength of these two air armies, they probably won't be able to break through the formation, thus rendering it ineffective.
In that case, all we need to do is maximize our ground attack capabilities!
There was a saying that Lu Changsheng always liked.
All fear stems from insufficient firepower!
"Huh? Aren't cannons used by mortal armies in battle? I've seen them before, but where's the cannon?" Divine Lord Hao Tian curiously tugged at the cannon's rope.
Lu Changsheng's expression changed, and he quickly cried out, "No..."
Everyone was a little puzzled. It's just a cannon, what's the big deal if you pull the trigger?
But before he could finish speaking, a loud "thump" resounded.
Instantly, a sphere of fire, imbued with the Law of Fire and mixed with some Dao Law of Destruction, shot out. Since the cannon was not adjusted, the shot struck the tower not far away!
Rumble!
In an instant, the sky collapsed and the earth cracked; the ground shook violently!
The ground was shaking violently, just like an earthquake!
The tower was reduced to dust in an instant!
Everyone stared in disbelief at the scene.
You call this a cannon?
Lu Changsheng shrugged and said, "Anyway, that's how it is. I didn't count them precisely when they were being forged, but there were probably around two hundred."
"Oh, to add, while there's no limit to the number of launches, after about four hundred rounds, the materials can no longer withstand the energy release, and the barrel will explode."
Everyone was stunned.
About two hundred units... about four hundred rounds each...
That's damn destructive power! It's comparable to a full-force attack from the Peak God Emperor Realm expert!
However, if Old Deng hadn't told Lu Changsheng not to steal the limelight and hadn't weakened all the artillery... well, let's not talk about showing off, it's unnecessary.
At this moment, the gentleman gave a wry smile, "If Fellow Daoist Lu had been alive in High Antiquity times, things probably wouldn't have turned out so tragically."
Even the Immortal Emperor couldn't help but ask, "When did you learn how to forge weapons?"
Such weapon-refining skills are Lu Changsheng even by the Immortal Realm!
"You didn't ask."
Immortal Emperor: "..."
"Alright, since that's the case, this is all we can do. The remaining task is one last round of manpower reallocation." The Immortal Emperor looked at the high mountain and said gravely, "There are less than two days left..."
Lu Changsheng nodded. "I have other things to do."
After saying that, he pulled Shi Sheng away and disappeared from the spot.
The Immortal Realm Passage.
Evil Qi permeated the entire passage! When Lu Changsheng entered, he could feel wisps of demonic energy swirling around him!
Shi Sheng asked, "Master, what are we doing here?"
"Could it be..." Suddenly, Shi Sheng's eyes lit up, and he said, "Master is going to take me directly to the enemy's headquarters for a raid?"
Upon hearing this, Lu Changsheng rolled his eyes and tapped Shi Sheng on the head, saying, "Kill you my foot! That would cause such a huge commotion!"
Although Lu Changsheng had ways to prevent others from discovering his actions.
But if such a vast Evil Devil Domain simply vanishes like that, wouldn't that attract the attention of those people Old Deng mentioned?
At that moment, a voice came from inside the Heaven-Suppressing Pagoda.
"It's come to this... Young friend, take the Heaven-Suppressing Pagoda with you; perhaps it can be of assistance."
Upon hearing this, Lu Changsheng looked at Shi Sheng, took out a gemstone that shimmered with a purple aura, and handed it to Shi Sheng, saying, "The purpose of bringing you here is to take away this Heaven-Suppressing Pagoda."
Shi Sheng was taken aback. "But it disappeared after the suppressing power was taken away..."
"Don't worry, the remaining suppressive force will hold out for the next two days."
Lu Changsheng nodded and said, "Besides, there's still some time left, so perhaps I can repair and improve this Heaven-Suppressing Pagoda."
Under the Eye of Heaven Scrutiny, the flaws of the Heaven-Suppressing Pagoda and the areas that needed repair were all clearly understood!
