Six gray-robed apprentice warlocks finally appeared on the city walls. These six Warlock Apprentices were the Wandering Warlock Apprentices that Viscount Heru had painstakingly recruited.

In the Turandot subcontinent, warlocks wield endless power and wealth. Formal Warlocks are recruited by some powerful group of Warlocks. It is rare for a formal warlock to be recruited by the nobility. Only the great nobles of the powerful empire could possibly recruit a full-fledged warlock.

"Greasy Technique!"

A warlock apprentice pointed at a sword soldier and performed a level 0 trick.

The mechanical knife soldier slipped and fell directly to the ground.

Several heavy alchemy heavy crossbows locked onto the mechanical knife soldier, and three terrifying heavy crossbows instantly shot at the mechanical knife soldier's body, blasting the mechanical knife soldier into countless metal fragments.

"Arcane Missile!"

An apprentice warlock pointed at another swordman, and an arcane missile flew towards the mechanical swordman like a bullet.

The arcane missile slammed into the mechanical knifeman's chest, sending the mechanical knifeman back a few steps, his chest slightly dented.

It's just that the mechanical knife soldier's body shook and continued to rush forward without any effect.

That level 0 magic arcane missile can severely damage a knight-level powerhouse with a single shot, but it doesn't do much damage to a robot like the mechanical knife soldier. On the contrary, the slash of a knight-level powerhouse poses a greater threat to the mechanical knife soldiers.

"Acid sputtering!"

A warlock apprentice pointed at him, and a streak of acid sprayed directly at a mechanical knife soldier.

As if someone had poured a basin of concentrated sulfuric acid on it, the mechanical knife soldier emitted bursts of white mist, which were corroded by the acid. Ordinary humans were splashed with the acid, and their upper bodies would be corroded, and they struggled in pain and were unable to fight, but the mechanical sword soldier continued to charge without any reaction.

"Acid sputtering!"

"Acid sputtering!"

"Acid sputtering!"

A series of four acid sputters sprayed on the mechanical knife soldier's body before the mechanical knife soldier's head was completely corroded, and he fell to the ground unable to move.

The six Warlock apprentices were so small that although they had collectively knocked down seven mechanical swordsmen, they were swept straight to the bottom of the castle by the mechanical swordsmen.

As soon as a mechanical knife soldier came to the bottom of the castle, he quickly stuck his alloy war knife behind his back, and raised his hands high. Another mechanical blader jumped directly onto its palms, then raised his hands in the air. One by one, the mechanical knife soldiers repeated this action, and quickly formed six human ladders.

A mechanical knife soldier jumped nimbly over the six human ladders, towards the castle.

"Arcane Missile!"

The six Warlock Apprentices were only able to perform this level 0 trick, using the powerful knockback power of the Arcane Missile to knock the mechanical knife soldier out of mid-air.

It's just that the agility of the mechanical knife soldiers is too perverted, after the first wave of mechanical knife soldiers was repulsed, the second wave of mechanical knife soldiers jumped directly to the city wall, and waved the alloy war knife in their hands to slash at the soldiers of the boulder fort on the city wall.

"Give me death!!" a knight dressed in knight's heavy armor and holding a giant sword roared angrily, bursting out with powerful life energy, sneaking in from the side, slashing at the head of a mechanical knife soldier, and cutting the head of the mechanical knife soldier directly away.

Before the heavily armored knight could catch his breath, six mechanical swordsmen rushed straight at him, twelve huge alloy swords slashing at him from six directions.

The knight was a powerful martial artist, but he only blocked two alloy swords, and was directly cut into pieces by the rest of the alloy swords.

There were a total of thirteen knight-level masters on the city wall, and those thirteen knight-level masters were quickly cut into pieces under the siege of that large number of mechanical sword soldiers. Even with the Warlock Apprentice behind him, those knight-level masters still couldn't stop the mechanical sword soldiers who exchanged death for death.

After all the thirteen knight-level masters were killed, the morale of the warriors on the city wall completely collapsed, and they fled in all directions, kneeling on the ground and begging for mercy.

Before the six apprentice warlocks could escape, they were directly surrounded by the swordsmen and cut into pieces, leaving only their heads.

"All men drop their weapons, and those who surrender on their knees will not die!"

Yang Feng gave an order, and those mechanical knife soldiers immediately shouted loudly while slashing those routed soldiers.

Most of the soldiers in the castle of Boulder City were the private soldiers of Viscount Heru, and their combat effectiveness and loyalty were far higher than those ordinary armies of Boulder City. Only some of them chose to surrender, and the rest of the rout soldiers who did not surrender were directly killed by the mechanical knife soldiers.

Viscount Heru was just a knight-level master, and he was quickly killed under the siege of seven sword soldiers.

The entire Boulder Fort also fell into Yang Feng's hands.

The main forces of the four major families in Megalith City took advantage of the opportunity of Yang Feng leading troops to attack Boulder Castle and took the opportunity to break through and leave Boulder City. In that megalith city, a large number of nobles also fled outside the boulder city with a large amount of gold and silver.

Yang Feng lost less than twenty mechanical sword soldiers in the capture of Megalith City.

After Yang Feng occupied Boulder City, he directly dispatched mechanical knife troops to attack the rural towns attached to Boulder City.

Those villages and towns attached to Boulder City were easily captured by Yang Feng's mechanical legions, and the lords who dominated those villages and towns were also directly cut down by Yang Feng.

A large amount of land was in Yang Feng's hands, and in that town, a large number of engineering robots were dispatched to build solar energy-absorbing umbrellas and arsenals.

After the entire sphere of influence of Giant Stone City was controlled by Yang Feng, the land he controlled was more than a hundred times larger than in the past. The area around Boulder City is rich in mineral resources. As long as the basic equipment is completed, the number of combat robots he can build every day will be more than fifty times that of the past.

Moreover, the construction of a large number of solar energy-absorbing umbrellas has allowed Yang Feng to no longer lack energy, and can gradually eliminate level 4 combat robots and produce level 6 and level 7 combat robots in large quantities.

Level 6 and level 7 combat robots are the strongest main battle robots that Yang Feng can currently mass-produce. The reason why Yang Feng chose to mass-produce level 4 combat robots before was because he had enough steel and lacked energy at that time. After mastering Boulder City, the situation was reversed, and it became full of energy and not enough steel.

The day after the capture of Boulder City, Yang Feng led the fully charged mechanical legion to advance in the direction where the Black Hut was located.

The information from Viscount Heru's head shows that the owner of the Black Hut is an old monster who has lived for more than a hundred years and has an extremely wide network. The Black Hut is a group of warlocks that not only befriend the warlock group behind the Duchy of Feendreo, but also has close ties to several warlock groups.

Once the Black Hut mobilizes its forces to seek help everywhere, Yang Feng may face more enemies than just a group of Black Hut Warlocks.

The capture of Boulder City was expected by Yang Feng, and the Black Hut was his real imaginary enemy.
