"Blow me up hard. If a hundred mechanical dogs can't explode, then I'll use a thousand or ten thousand! I want to see how hard this devil's fortress is!"

The mechanical dogs produced by Wu Feng during this period showed their power at this time. A steady stream of mechanical dogs frantically attacked the city wall. After sacrificing thousands of mechanical dogs, they finally blasted several gaps in the city wall.

The blood corpses immediately swarmed in, and the first line of defense was immediately declared broken! The firepower of the demon fortress was immediately greatly reduced.

At this time, the few demon lords stationed in the fortress could not sit still. According to this posture, their fortress would not be able to hold on for long.

Originally, they stationed in the fortress to integrate the demon army here and sweep away many lords from the two regions in one fell swoop.

As a result, their demon fortress was the first to be attacked! This was unacceptable to the demon lords, so they mobilized their elite armies and prepared to fight tooth and nail!

"Aurora, facing the demon lord, you can take action! Let's launch today's natural disaster!"

Seeing the Demon Lord's elite troops appear on the second line of defense, Wu Feng decisively used his trump card. Aurora nodded and launched a natural disaster against the Demon Fortress.

I saw that she triggered the meteor shower and sky fire, and countless meteorites and sky fire fell from the sky, hitting the devil's fortress.

The natural disaster triggered by Aurora was enough to cover most of the Demon Fortress, with countless meteorites and sky fires, causing heavy casualties to the Demon Lords and causing great damage to the Demon Fortress.

Wu Feng looked at the destructive power of the natural disaster and nodded: "Aurora's natural disaster is indeed powerful, but its coverage area is fixed. If it is to deal with the enemy's army, its movement needs to be restricted."

"This natural disaster is best used against fixed buildings or territories, so that its power can be maximized."

Natural disasters are now used to deal with fixed demon fortresses. Since the entire demon fortress cannot be moved, it can only be carried by force.

Under the offensive of natural disasters + sea of ​​blood + mechanical dogs, the demon lords could only watch as their armies suffered heavy losses and were submerged by the boundless sea of ​​blood.

The second line of defense, after holding on for 2 hours, was also breached. At this time, the Devil's Fortress was left with only the last line of defense.

The Devil's Eye defense tower is also on this line of defense.

Blood Shadow has already lost thousands of people to the attack of this defense tower, and Wu Feng has also been eyeing this defense tower for a long time.

So Wu Feng called the old prostitute over: "Old prostitute, look at this defense tower. Can you force it to be rented?"

After Mr. Prostitute landed, he saw what Wu Feng was doing. He was shocked when he saw the devil's fortress that was about to be pushed flat.

"Brother Feng, you are going against the will of God! You are actually attacking the Devil's Fortress, and it is almost over!" Teacher Piao was really shocked.

Territories of natural disasters such as Devil's Fortress are super resource points that guard the borders of the region, and there are a large number of Devil's lairs nearby.

Generally speaking, it was the lords who formed an alliance and overthrew the Demon Fortress together, but now Wu Feng did it alone!

The most important thing is, looking at this posture, Wu Feng is not far away from successfully pushing the Devil's Fortress. This is the final offensive!

"What does this mean? If it hadn't been for the natural disaster that happened today, I would have demolished the Devil's Fortress long ago!" Wu Feng waved his hand and pointed at the Devil's Eye, indicating that the prostitute teacher could start working.

Teacher Prostitute also used expansion land to connect it to the Devil's Fortress. After they were adjacent, he launched forced leasing, and it really succeeded!

With the success of the rental, the Devil's Eye, which had been attacking Blood Shadow, began to attack other devil heroes. The Devil's Eye continued to stare at an orange devil hero. After a few seconds, it killed the opponent instantly!

Seeing this scene, Wu Feng was very surprised. The Devil's Eye was still in the deepest part of the Devil's Fortress, but it was already controlled by the prostitute.

It turns out that when forced leasing is used to deal with this kind of fixed building, it is equivalent to instigating the rebellion of this building in the defense line. In the death trial, the ability of the prostitute teacher is simply unbelievable!

Even legendary defense towers can 'incite rebellion', which can directly collapse the enemy's defense line. Forced rental of skills is too powerful.

However, after the Demon Eye was instigated to rebel, it was immediately targeted by the Demon Lords. Since the Demon Eye stood alone in the Demon Fortress, surrounded by enemies, these Demon Lords could also organize forces to besiege the Demon Eye, and its durability would decrease.

Fast.

Seeing this scene, Wu Feng couldn't bear it. This was his thing, how could he let the demon lord destroy it.

He only asked Mr. Prostitute to try it after he reached the third line of defense. This was to prevent the rented items from being damaged. Now that there was only one line of defense, he could speed up the progress!

"Harlin, it's your turn! Blast me hard and let these demon lords see the power of art! You must blast this line of defense for me before the Devil's Eye is destroyed!"

Without the threat of the Devil's Eye, Harlin could play, so Harlin temporarily abandoned his work of making mine bombs and rushed to the Devil's Fortress. He personally started the explosion. If you didn't believe it, you still couldn't blow up the Devil's Fortress!

So Harlin picked up a large bag of perfect bombs, aimed at the third line of defense of the Devil's Fortress, and threw a cluster bomb!

In this wave, he used 150 perfect bombs. Such bombs made with perfect resources are worth more than 100,000.

Using so many perfect bombs together is just a waste of money!

The power of the cluster bombs is indeed incredible. This wave of bombs was thrown in front of several perfect-level defense towers. As the mushroom cloud rose, these defense towers and the city walls were sent into the sky together!

With one cluster bomb, the third line of defense of the demon fortress collapsed. Countless blood corpses and blood shadows also rushed into the deepest part of the fortress. The demon lords were immediately overwhelmed by the blood shadows and soon turned into mummies.

Half an hour later, the battle ended. Except for the Devil's Eye and a few buildings that were preserved, almost all other defense facilities in the Devil's Fortress were destroyed.

In the deepest base camp of the Devil's Fortress, there is a Devil's Heart, which is equivalent to the Lord's Heart. After its destruction, the Devil's Fortress was captured by Wu Feng.

So Wu Feng immediately took action, and the blood corpses quickly destroyed the devil's heart.

[Ding...Successfully destroyed the Devil's Heart, breached the Devil's Fortress, completed the Pathfinder achievement, and obtained 2,000 hunting points.]

[Ding... Successfully break through the Devil's Fortress and clear Area 033 and Area 034. You will get an additional 5,000 challenge points. 】

After taking down the Devil's Fortress, Wu Feng gained a lot of hunting points and challenge points. These are all contents of special permissions, which instantly made Wu Feng 'rich'.

Wu Feng can also successfully connect the two areas, and he can expand to area 034.

If the Devil's Fortress is not breached, then Wu Feng will have to rely on teleport cards to go to area 034, and he has to use orange teleport cards that can cross regions.

If you encounter fierce resistance in Area 034 and need to dispatch reinforcements, the consumption of teleportation cards will be extremely shocking.

Now that the two areas have been opened, Wu Feng can organize an army to conquer area 034. He can even launch the legendary Southern Barbarian invasion card in area 034.

At the same time, the large number of demon lairs outside the demon fortress can also become Wu Feng's resources. He can build a circle of defense towers here to reach these demon lairs.

"These mountains around the Devil's Fortress have ore resources! These many mines are enough for me to dig out massive resources!"

"Devil's Fortress must build a powerful sub-base!"

Wu Feng had already had the idea of ​​​​the Devil's Fortress. He knew the resources around the fortress very clearly. After taking the fortress, he immediately started operations.

Defense towers were summoned one after another, and batches of engineering robots were sent over to build the Titan Wall directly at the original site of the Demon Fortress.

This time the Titan Wall can be built to a length of 100 kilometers, and it can seal the corpse of the fallen giant inside!

At the same time, a large number of mining robots were pulled near the Devil's Fortress, and they began to dig in the surrounding mineral veins.

The border areas of such areas are generally very rich, with a lot of resources and minerals. This is also a hidden reward for the lords who conquer the border areas.

Wu Feng's mechanical army can continuously blast out troops as long as it has enough resources. Now he is constantly laying down resource points, and then mining the resources to manufacture various mechanical weapons.

Now he not only has the resources of the entire No. 033 area to utilize, but he can also plunder a large amount of basic resources through the invasion of the Southern Barbarians.

Because today is March, the Southern Barbarian invasion has the best effect. The grassroots resources Wu Feng plundered are piled up, which is enough for him to explode a wave of troops!

So Wu Feng rebuilt a steel city at the original site of the Devil's Fortress. Various machinery factories could also be set up here and began to explode troops with all their strength!

"Today's mechanical technology, let's choose this kind of warrior armor. It can create mechanical armor for other arms and improve the combat effectiveness of the arms."

"The mechanical creations in the territory have been established for the time being. This kind of armor can be built!"

Wu Feng was building a mechanical factory like crazy in the City of Steel. He simply used a technology called Lux ​​Armor for today's slot in the Mechanical Heart!

This kind of technology can make armor factories and produce warrior armor. This type of armor comes with its own power system, weapon system and auxiliary combat system.

If the orange unit is equipped with a set of orange armor, its combat power will soar. It is no problem for one to challenge two or three of the same level!

The Lux Armor is also divided into multiple professional versions. What Wu Feng activated today is the shooter version of the Lux Armor. This is legendary technology!

In other words, after building an armor production factory, Wu Feng can produce up to legendary-level Hercules armor, which can greatly increase the combat effectiveness of legendary-quality units.

However, considering that the current shooter Lux armor was prepared for heavy artillery gunners, he gave priority to the production of perfect quality Lux armor, which was exactly in line with the quality of heavy artillery gunners, and the output was also higher.

"One armor factory can produce 500 orange Lux armors a day, so let's build two armor factories first! Maximize the production capacity!"

Wu Feng built an armor factory in the City of Steel and a mechanical sub-base respectively. You can't put all your eggs in one basket!

After the two armor factories were completed, Wu Feng was able to produce 1,000 pieces of orange Lux armor every day. In a few days, he could arm all the heavy artillery gunners.

They will become an extremely powerful long-range army, and they will definitely kill everyone!

After all, without the boundless sea of ​​blood, Wu Feng would not be able to sweep away the enemy lords so easily.

After activating the new technology, Wu Feng tried to use the Artisan's Book to record the technology in the heart of the machine. Unexpectedly, it actually worked!

However, the Artisan's Book can only record producible weapon technologies such as the Lux Armor, which is limited to technologies such as mechanical dogs.

After Wu Feng entered them all, he gained a lot of attribute growth!

[Ding... The book of craftsmen records the success of outstanding technology (mechanical dogs, mining robots, machine gun robots), triggering knowledge is the power effect, the lord's intelligence attribute is permanently increased by 60 points, and the spiritual attribute is increased by 60 points. 】

…

[Ding... The book of craftsmen records the success of perfect-level technology (heavy artillery tanks, transforming artillery, engineering robots), triggering knowledge is the power effect, the lord's intelligence attribute is permanently increased by 150 points, and the spiritual attribute is increased by 150 points. ]

…

[Ding... The Artisan's Book records the success of the legendary technology (swarm robot), triggering knowledge is the power effect, the lord's intelligence attribute is permanently increased by 500 points, and the spiritual attribute is increased by 500 points. 】

…

[Ding... The Artisan's Book records the success of the legendary technology (shooter-type warrior armor), triggering knowledge is the power effect, the lord's intelligence attribute is permanently increased by 500 points, and the spiritual attribute is increased by 500 points.]

Wu Feng's intelligence and spiritual attributes skyrocketed again, but the level of the Luan Bird fighter technology crystal was too high, and the mechanical heart had not yet analyzed this technology.

The Artisan's Book cannot record this technology. After all, the Artisan's Book cannot directly record a mass of technological crystallization.

With Wu Feng's production capacity at full capacity, the Heart of Machinery also successfully upgraded to level 5, and randomly activated a crab robot technology.
