Rumble! Rumble! Rumble!

With the destruction of the robots and rune cannons on the third line of defense, the third line of defense has all fallen, without the slightest use value, a large number of rune bombs installed in the fortress of the third line of defense were detonated, and the powerful explosive power directly destroyed all the fortresses on the third line of defense, turning them into ruins, and the innate demon soldiers on the third line of defense were also blown into flying ash and flesh fragments at the first time.

However, the innate demon soldiers who suffered heavy losses in the explosion of the second line of defense learned the lesson of the second line of defense, and the number of innate demon soldiers on the third line of defense was very small, and the losses were extremely limited.

"Kill! Kill! Kill! ”

After all the fortresses on the third line of defense exploded, the innate demon soldiers immediately crossed the third line of defense, like a tide, and rushed in the direction where the fourth line of defense was located, preparing to destroy all eighteen lines of defense in one go.

"Open all the primary rune cannons on the line!"

Yang Feng, who was sitting in Huangsha City, saw that the innate demon soldiers had broken through the two lines of defense after only losing millions, and if it continued, it was likely that he would destroy all the eighteen lines of defense he had established before the losses were exhausted, so that his plan to annihilate the demon army here would fail, so he did not hesitate and immediately increased his attack force.

With Yang Feng's order, the primary rune cannons on the defense line were pushed out, aiming at the direction where the innate demon soldiers were, letting out a roar one after another, and one rune cannonball, like raindrops, poured out in the direction where the innate demon soldiers were.

Rumble! Rumble! Rumble!

In the sound of violent explosions, one rune cannonball after another fell into the group of innate demon soldiers and exploded, and the powerful explosive power directly killed the nearby innate demon soldiers mercilessly, causing them to die tragically on the spot.

The power of the primary rune cannon is powerful, and all the lifeforms below the mana realm within a hundred meters of the rune cannonball cannot withstand the explosive power generated by the explosion of the rune cannonball, and they will be directly killed or shocked to death.

Yang Feng installed 10,000 primary rune cannons on each line of defense, and a total of 150,000 primary rune cannons were installed on the fourth to eighteenth lines of defense, a total of fifteen thousand primary rune cannons.

Every time the 150,000 primary rune cannons are shelled, 150,000 rune cannonballs will be emitted, and these 150,000 cannonballs explode, with powerful explosive power, directly enveloping a large area, and tens of millions of innate demon soldiers were directly killed on the spot.

It is no exaggeration to say that as long as the 150,000 primary rune cannons continue to bombard for a period of time, they can easily bombard the 40 million innate demon soldiers, causing them all to turn into flesh and blood fragments and scatter towards the ground.

It's just that in the face of the ferocious attack of the 150,000 primary rune cannons, the innate demon soldiers will not sit still at all, and disperse at the first time, minimize the damage of the rune cannonballs, and organize death squads to launch a ferocious attack in the fourth direction.

Suddenly, I saw a phalanx composed of 100,000 innate demon soldiers, releasing a huge and incomparably demonic energy cover, and under the dense artillery fire, they were not afraid of life and death and rushed towards the direction where the fourth line of defense was located.

Rumble! Rumble! Rumble!

In the sound of violent explosions, the innate demon soldier phalanx that was charging at the forefront was covered by dense rune shells, and the huge demonic qi shield was directly destroyed, turning into a little light and disappearing into nothingness.

Immediately afterwards, the dense rune shells fell into the Congenital Demon Soldier Phalanx like raindrops, and the powerful explosive power directly killed all the Innate Demon Soldiers in the Innate Demon Soldier Phalanx on the spot, causing them all to turn into flesh and blood fragments, and blood spilled on the ground.

In just a quarter of an hour, dozens of innate demon soldier phalanxes were destroyed, millions of innate demon soldiers were ruthlessly bombarded, and the remaining innate demon soldiers took the opportunity to attack the fourth line of defense, destroying the robots and rune cannons on the fourth line of defense, turning it into a ruin.

Even, the entire fortress on the fourth line of defense was shattered under the attack of the angry innate demon soldiers, turning into countless fragments and falling downward.

Rumble! Rumble! Rumble!

Seeing that the fourth line of defense was destroyed, Yang Feng did not hesitate or hesitate at all, and immediately detonated the massive rune bombs buried in the depths of the fortress of the fourth line of defense, causing them to explode, taking away the lives of more than 100,000 innate demon soldiers.

With the fall of the fourth line of defense, the remaining more than 30 million innate demon soldiers, stepping on the corpses of their companions, let out angry roars, agitating the demonic energy in their bodies, waving the sharp weapons in their hands, and fearlessly surging up, regardless of their own casualties, to charge towards the fifth line of defense.

In the face of the fierce charging Innate Demon Soldiers, the dense artillery fire continued to roar, pouring powerful rune cannonballs into the Congenital Demon Soldiers, taking away the lives of a large number of Innate Demon Soldiers.

At the same time, the acquired robot on the fifth line of defense, holding a primary rune gun, shot at the innate demon soldiers who were charging forward, and shot the innate demon soldiers who charged in front mercilessly.

However, the number of innate demon soldiers was too many, and after paying a large number of casualties, a congenital demon soldier approached the vicinity of the fifth line of defense, and one after another fierce attacks swung out from the body of an innate demon soldier, with an extremely sharp edge, falling on top of the fifth line of defense, ruthlessly destroying a robot and a primary rune cannon on the fifth line of defense.

Yang Feng, who was sitting in Huangsha City, looked at the fierce battle on the virtual screen, and a faint smile appeared on the corner of his mouth.

There is not a single human on the eighteen lines of defense, all of them are robots and rune cannons, even if all the eighteen lines of defense are destroyed, Yang Feng will not be heartbroken, and he will only lose some money and energy points.

Of course, it was just tens of millions of innate demon soldiers, and it was impossible to destroy the eighteen lines of defense at that time, because Yang Feng had a killer weapon on the eighteen lines of defense, and he could easily kill tens of millions of innate demon soldiers.

It's just that the killer weapon on the eighteenth line of defense is not for tens of millions of innate demon soldiers, but for the elite backbone of the second batch of demons.

Under Yang Feng's close attention, the remnants of more than 30 million innate demon soldiers, like a tide, launched a fierce charge towards the defense line after defense, destroying the defense line after defense line at a great price.

In just a few hours, the eighteen lines of defense were destroyed by the innate demon soldiers twelve of them, and the number of innate demon soldiers also decreased from tens of millions to millions, and there was no way to continue to destroy the thirteenth line of defense.

Rumble! Rumble! Rumble!

In the sound of violent explosions, the remaining millions of innate demon soldiers suffered heavy casualties in the dense artillery fire, and the more than 100,000 innate demon soldiers who persevered to the end also turned into a piece of fly ash with the self-explosion of the thirteenth line of defense, and completely disappeared from this world.

"I didn't expect that more than 40 million innate demon soldiers would destroy thirteen of the eighteen lines of defense they had established, and it was already impossible to rely on the last five lines of defense to annihilate the demons! I hope that the trump card I have arranged can play a role and wipe out all the demons here! ”

When more than 40 million innate demon soldiers were wiped out, Yang Feng, who was sitting in Huangyan City and witnessed the entire battle process, whispered to himself with a smile on his face.

After a whisper, Yang Feng sent an elite army composed of 140,000 personal guards and more than 2 million innate martial artists to clean up the battlefield, picked up more than 40 million innate demon cores, and by the way, counted the corpses, armor, weapons and other trophies of the innate demon soldiers.

Although most of the armor and weapons on the Innate Demon Soldiers have been destroyed, many of them remain intact, which can be regarded as a good fortune, and the corpses of the Innate Demon Soldiers are also considered a resource, whether they are used to feed the bloodthirsty vines or to exchange for various materials, it is a good choice.

The speed at which more than two million elites cleaned up the battlefield was very fast, and the more than 40 million Innate Demon Cores that were scattered on the ground were gathered and sent to an exchange pillar in Huangyan City.

Looking at the mountains of innate demon cores in front of him, a faint smile appeared on the corner of Yang Feng's mouth, a smile of expectation appeared on his face, and he said in a relaxed tone: "Completely exchange these demon cores for imperial merits!" ”

As soon as Yang Feng's voice fell, a ray of light emanated from the exchange pillar, enveloping more than 40 million innate demon cores, and a clear blood-colored handwriting appeared in Yang Feng's mind: "4.5 million innate demon cores, worth 450 million imperial merits, do you confirm the exchange?" ”

"Confirm!" Yang Feng responded without the slightest hesitation or hesitation.

With Yang Feng's confirmation, the mountains of innate demon cores turned into streamers and rushed into the exchange pillar, and Yang Feng's merits also became more than 457 million.

"Upgrade my title to a first-class viscount!"

Glancing at his merit value, Yang Feng said with a calm face.

As soon as Yang Feng's voice fell, Yang Feng's title was automatically promoted from a fourth-class viscount to a first-class viscount, and the territory also increased from six million square kilometers to nine million square kilometers, and the meritorious service was automatically deducted from 300 million, leaving more than 3,757 million.

"There are still 6.25 billion imperial merits left, and I can be promoted from a first-class viscount to an first-class earl, and it is also the highest title that the exchange pillar can exchange!"

Looking at the knighthood exchange list on the exchange pillar, Yang Feng's face showed a strong look of expectation, and he muttered to himself in a pleasant tone, and began to check his attribute panel.

"Host: Yang Feng

Territory: Qinghe Village (10,000 square kilometers), Liusha City (9,000,000 square kilometers)

Power Points: Thirty"

"System, buy me ninety Jindan early stage combat robots!"

Looking at his new thirty energy points, Yang Feng hesitated slightly, and then spent the thirty energy points.
