Chrissy's golden fist struck down and directly killed the fourth-level undead lord. Chrissy killed the fourth-level undead lord instantly, which was almost like killing a chicken.

[Ding... The Supreme Alliance kills the hero of the Undead Legion and obtains 360 alliance experience points based on the hero's level (Level 4, 120) and quality (orange).]

[Ding... The Supreme Alliance kills the hero of the Undead Legion and obtains 380 alliance experience points based on the hero's level (Level 4, 125) and quality (orange).]

[Ding... The Supreme Alliance kills the lord of the undead army and obtains 1,000 alliance experience points based on the lord's level (level 4, 125). 】

…

Chris's punch killed an astonishing number of heroes and lords in total, and Wu Feng once again enjoyed the benefit of swiping the screen.

In this wave, he harvested more than 4,000 alliance experience points. The fourth-level lords and heroes gave more experience points than the third-level ones. The upgrade progress of the Supreme Alliance also reached 80,000/10,000.

According to this posture, if the difficulty of the natural disaster fortress is increased and the rewards are also increased, then Wu Feng has a chance to upgrade the Supreme Alliance to level 2!

The lava chariot cooperated with other troops to tightly surround the undead army. Finally, after 20 minutes, the undead army was completely wiped out, and no undead hero could escape.

As countless undead heroes were killed, no one could stop them in the entire third level. Wu Feng also led the team into the undead fortress, where Teacher Saitama was playing with some skeletons and zombies.

"It's really strange. These undead souls can move all the time without eating. Where do their energy come from?" Teacher Saitama is completely studying the characteristics of various natural disaster alien races.

He pulled the skull's head off and put it back on again, or stepped on the zombie's feet to see if the zombie's joints could twist.

Anyway, these undead souls are no more than toys in his hands. In this case, Teacher Saitama is not even considered to be in a fighting state.

Wu Feng ignored Teacher Qiyu, but went straight into the deepest part of the Fortress of the Undead and blew up the Heart of the Undead.

[Ding...Successfully destroyed the Heart of the Undead, breached the Natural Disaster Fortress (third level), completed the Pathfinder achievement, and obtained 8,000 hunting points.]

[Ding... Successfully broke through the natural disaster fortress (the third level) and cleared the third level of the ninety-nine natural disaster levels. You will get an additional 15,000 challenge points, and the number of members of the destiny protagonist organization will be +1.]

[Ding... Successfully break through the natural disaster fortress (the third level) and clear the third level of the ninety-nine natural disaster levels, you will get an additional 15,000 alliance experience points. ]

The third level was announced and Wu Feng was not in a hurry to advance to the fourth level. Several heroes also respected Wu Feng's decision and directly followed it.

The First Emperor asked his Xian Qin Legion to take a rest, and while they were refilling their war equipment with ammunition, Teacher Saitama, like a hunting dog with a keen sense of smell, found the hidden building in this level.

The buildings in the Fortress of the Undead are still Death Tombs. It seems that fortresses of the same race have the same type of hidden buildings.

After all, it is an orange-quality hidden building. Wu Feng moved it directly back to the main base. Whether he uses it himself or trades it to [Two Hairy Legs], it is good.

While resting, Brother Zheng also summoned his Xian Qin Legion again! The further the level goes, the more troops he will gain.

[Ding... Yingzheng conquered the Fortress of the Undead (the third level), and received conquest rewards based on the size of the territory, including 3,000 terracotta warriors and horses, and 4,000 Immortal Qin archers! 】

[Ding... Ying Zheng conquered the Fortress of the Undead (the third level), triggered the Immortal Qin Empire bonus, increased the conquest reward by 170%, and obtained 5100 terracotta warriors and 6800 Immortal Qin archers! 】

Zheng Ge gained tens of thousands of powerful soldiers in one wave. His total losses in the third level were only a few thousand people. This wave directly increased the number of his legion members instead of decreasing, which is simply outrageous.

Under normal circumstances, if you want to attack these fortresses, you will have to suffer heavy losses.

But Wu Feng adopted a strategy of throwing coins, that is, exchanging money for troops. This is the strategy Wu Feng chose to consume more magic crystals and less troops.

"Lord, we can start attacking the fourth fortress! My army is enough to sweep away the enemy!" Brother Zheng confidently asked Wu Feng for a fight.

Looking at the larger army, Wu Feng agreed to his request, so the Xian Qin Army dispatched again.

As rows of war equipment arrive in front of the fourth natural disaster fortress, a fierce battle is about to begin.

This natural disaster fortress has become a demon fortress, and the demons inside are naturally much higher level than the first fortress.

However, the continuous bombardment of many war instruments was enough to destroy this demonic fortress. Wu Feng decided that the worst case scenario would be to smash 2 billion magic crystals down!

At this time, there were other movements in the Devil's Fortress. Following bursts of loud noises, countless gargoyles flew out of the Devil's Fortress.

This kind of flying creature can avoid artillery fire, like lava chariots and lava cannons, and cannot attack gargoyles at all.

Moreover, slow-moving lava catapults, lava cannons and other war instruments are also most afraid of such fast approaching flying enemies. When the gargoyles flying over the mountains and plains, Wu Feng quickly asked the Xianqin Legion to cover many war instruments and return.

rush.

Fortunately, Wu Feng had the Twelve Golden Men and the Mountain Divine Soldiers on his side. They were both huge behemoths who could carry these war instruments away and greatly speed up the movement of the war instruments.

They don't need to move the lava chariot, they only need to move the catapult and cannon.

"Lead these gargoyles to the Great Wall of Despair. If they dare to come, I will kill them all!"

Wu Feng also didn't expect that there would be so many gargoyles among the enemies in the fourth level. This special existence was somewhat similar to the golem, as they were both once created by engineering.

But then a master of engineering sold his soul to the devil and transformed his best gargoyle into a half-golem, half-demon creature.

The demons can use special methods to produce gargoyles in large quantities. This cheap and easy-to-use cannon fodder unit has become the favorite cannon fodder of the abyss demons.

Now, there are a large number of gargoyles stored in the fourth Demon Fortress. Their primary target is the catapults and cannons below. Once these war instruments are eliminated, the Xianqin army will not pose much of a threat to the Demon Fortress.

Wu Feng saw the situation very quickly and ordered all the war equipment to be withdrawn. With the cover of Chris, Feng Yun and others, the war equipment quickly entered the protection range of the Great Wall of Despair.

The gargoyles still did not stop under such circumstances and chased them all the way. Wu Feng naturally would not be polite to them. He deliberately used war equipment as bait to lure the gargoyles into the range of the desperate barrier.

The gargoyles didn't know it yet, but they had penetrated deep into the most dangerous place. These dark creatures bravely withstood the firepower of the Xian Qin army and threw themselves at the war equipment without fear of death.

The war instruments were also city armor, but not so fragile. The gargoyles were constantly being bombarded by artillery fire, but they still continued to attack each other. Each war instrument was like a honeycomb filled with bees.

If this continues, the ants will bite the elephant to death, and the war instruments will sooner or later be destroyed by the gargoyles.

After seeing that the durability of war equipment dropped by nearly half, and that most of the gargoyles had penetrated deep into the desperate barrier area, Wu Feng decisively launched the Forbidden Air Realm!

As the forbidden air realm expanded, the gargoyles that were flying in the sky were all smashed down like stones.

Like the previous flying demons such as the harpy demon, the gargoyles were unable to resist the power of the forbidden air realm. The gargoyles in the sky were cleared, and by the way, the sky was also a lot cleaner.

In the forbidden air realm, one can distinguish between friend and foe. Even if the gargoyles fall, Chris can still fly.

In the past, the Great Wall of Despair relied on this ability to allow the lord's aerial army to crush the natural disaster aliens. Now the forbidden air domain has once again shown its power. Wherever the Great Wall of Despair is located, the natural disaster aliens can no longer do whatever they want!

The sky in Wu Feng's territory is not a place for natural disasters and alien races to run wild!

"Chris, the First Emperor has another chance to harvest! Fengyun also gives me crazy output! Kill all these gargoyles!"

Wu Feng said hello, and the First Emperor immediately commanded the Xian Qin army to turn around and madly output the gargoyle legion. These gargoyles, like the harpies, were all stuck by the desperate barrier and could only become lambs to be slaughtered.

The Xian Qin army seized the opportunity and killed each gargoyle. These were all enemies of level 4 or above. The experience and rewards for killing over levels were very rich.

This kind of enemy that cannot resist is very rare. The Xian Qin army roared and output like crazy one by one, and one gargoyle was destroyed one after another.

[Ding... The Supreme Alliance kills the hero of the Twin Ghost Legion and obtains 560 alliance experience points based on the hero's level (Level 4, 140) and quality (orange).]

[Ding... The Supreme Alliance kills the hero of the Twin Ghost Legion and obtains 580 alliance experience points based on the hero's level (Level 4, 145) and quality (orange).]

…

Wu Feng knew the enemy's legion number through the kill records. The Double Ghost Legion was different from the ordinary demon legion. It had a special legion name and was already very powerful.

It's a pity that they met Wu Feng and his powerful heroes. Now the Double Ghost Army has been tricked by Wu Feng again, and the losses are extremely heavy!

"Very good. Once this legion is destroyed, the progress of the alliance's upgrade will be improved. Level 4 heroes and lords will indeed give the alliance a lot of experience points."

Just as Wu Feng was thinking about it, a group of ground troops rushed out of the Demon Fortress. They were demons that were pitch black and had a strange sheen like graphite.

This is the soul-eating ghost among the twin ghosts of heaven and earth!

The Twin Ghosts of Heaven and Earth are the names the lords give to gargoyles and life-eating ghosts. These two special monsters are cannon fodder that can be mass-produced by demons.

However, they are also very powerful, with large numbers, fast speed, and strong attack power. When demons use them to fight, they always attract firepower and cause trouble to the enemy.

On many battlefields, when the twin ghosts of heaven and earth rush into battle, the enemy has to waste some energy on the twin ghosts of heaven and earth, and the demons can take advantage of the opportunity.

When Wu Feng encountered the invasion of the demon lord in the simulation game, he suffered a lot from the twin ghosts of heaven and earth. He hated the twin ghosts of heaven and earth deeply.

The demon lords he met now were not yet at the fourth level of power, so he had not encountered the twin ghosts of heaven and earth very often. This time it was considered a preview.

Now that the gargoyles had just suffered a big loss in front of the desperate barrier, the life-eating ghosts rushed out again. This kind of demon that ran very fast on the ground, got down on all fours, and rushed towards the Xian Qin army like a vicious dog.

Wu Feng was well prepared for this. He called out: "First Emperor, use your chariot to hit me hard and let these soul-eating ghosts know how powerful we are!"

Following his order, the Xianqin army all began to fire the giant cannons on their chariots to blast away. With the chariots protecting them, they did not have to worry about the attacks of the Soul Eaters.

After the Soul Eater jumped onto the chariot, it started biting madly. Generally speaking, the troops that were approached by the Soul Eater would fall into a certain amount of chaos.

The Soul Eaters' ability to rush into battle was very strong, but they encountered monsters because Wu Feng had prepared a large number of steel chariots for the Xian Qin army.

After Wu Feng obtained the lava arsenal, he has been maximizing the arsenal's production capacity and producing a large number of lava tanks every day.

When the number of chariots reaches a certain scale, they are almost invincible on the battlefield, and even many knight corps cannot shake the chariot corps.

Almost all the archers in the Xian Qin army were in chariots, and the sharp claws of the Soul Eater were a little stretched in front of the steel chariots.

Their attack would be too difficult for them if they wanted to break the city armor. Although their attack speed was fast, they could only slowly gnaw at the chariot.

At this moment, Wu Feng also fought and retreated, allowing the Xianqin army to bring the Soul Eater troops within the firepower range of the Great Wall of Despair.

When the many cannons of the Meteorite turret fired together, the Life Eaters were stunned because they were covered by an astonishing amount of firepower.

The firepower of various giant cannons fell on them like nothing, and the Life Eater immediately suffered heavy losses.

They were all blasted into the sky by various attacks, and the Soul Eaters also suffered heavy losses. With the mechanical army and the city defense, the Soul Eaters could only be beaten passively.

It can be said that Wu Feng used this trick to lure you into the urn, and by playing with it, he turned the siege battle into a city defense battle.

When the two ghosts of heaven and earth wanted to escape back, Wu Feng immediately chased them out and killed them immediately. They suffered heavy losses. Even a fourth-level peak demon lord was killed. This was a member of the two ghosts army.

One of the group leaders is a gargoyle lord.

[Ding... The Supreme Alliance kills the demon legion lord and obtains 1160 alliance experience points based on the lord's level (level 4, level 145).]
