The border of the Thorn Flower Empire was full of artillery fire, countless soldiers were killed and wounded every moment, and the magic cannons at the head of the Black Stone City also exerted terrifying power, plowing the earth into thick and heavy scars.

A large number of magic crystals are also being consumed rapidly.

However, the Thorn Flower Empire's reserves of magic crystals have also reached a very exaggerated level, and Black Rock City is a border heavy, after Wang Chen's victory in the Battle of Renslowlor, the Thorn Flower Empire has also stepped up the transfer of a batch of magic crystals into Black Rock City, and also tried to use these powerful magic cannons with various magic props to block Wang Chen's offensive......

Therefore, for a moment and a half, although the magic cannon cluster fired with all its might, the magic crystals were still sufficient.

Far from exhaustion.

A short period of consumption is tantamount to a drop in the bucket for Black Rock City!

Zizizi――

A large number of scorpions were also behind the mixed forces of the besieging humans and the Zerg legions, and they were also assembled, the tail needles behind them were also raised high, and the silver-white plasma balls the size of fists were also condensed.

"Put!"

Arold also ordered.

Call!!

In the next moment, the plasma ball that almost covered half of the sky also rose, and in the frightened eyes of countless city defense soldiers, it also drew a parabola, like the sea pouring down towards the Black Rock City below!

"Quick!"

"Raise the magic shield!"

There is a magic cannon in Blackstone City, and naturally a complete magic protection system is also placed. It's just that there is no need to open the magic shield when it is not necessary, and the consumption of magic crystals by this super-large magic shield is simply exaggerated to the extreme.

A short period of time is enough to make the magic cannon cluster bombard indiscriminately for a long time.

At this moment, until the plasma ball attack came, the overwhelming power also made the thorn flower general defending the city have to open the magic shield......

Wow~~~~

The plasma ball fell, killing some of the city defense soldiers who were hit head-on, and the terrifying plasma also carried the high temperature, vaporizing the torsos of some soldiers.

But. The next moment. A pale blue magic shield rose around Black Rock City!

Airplanes~~~~~~

With the abundant supply of magic crystals, the heavy light of light blue enveloped the entire city almost instantly, and also blocked the large number of follow-up plasma balls that had not had time to fall out of the shield.

Light blue magic shield. Suddenly, there was a dense crashing sound. Large swaths of silver electric light also spread.

Crackling-

After a dense popping sound like fried beans. All the city defense soldiers breathed a sigh of relief.

"Blocked!"

"Open the city defense-grade magic shield!"

"These strange attacks with electric power are all blocked by protective shields!"

"We're safe......"

Many of the recruits cheered and even got carried away. After all, they were all newly trained soldiers, far less calm than those veterans, and there were many veterans in Blackstone City. At this moment, they are still using magic cannons to bombard the enemy.

The war is not over.

They know that this is not the time to cheer victory......

……

Arold also looked at Blackstone City, where the magic shield was raised, and watched the heavy magic shield block all the plasma balls with ease, but he was still unmoved.

"Tank Bug Troops!"

"Underground Offensive!"

Arold quickly issued an order, although the underground of Black Rock City would also be wrapped in a magic shield...... But the weakest link of this magic shield is still underground, and it is much easier to break through from here.

If you have a large number of tank bugs spewing lava breath together.

If he goes into battle in person.

With the power of the Legendary Realm, with the attack, I believe that it won't take long to break the magic shield that seems to be majestic now......

Arold didn't think he was as strong as the Sorrowful Wind, and the surface of Blackstone's city-grade magic shield was much stronger than the kind of magic shield they had used in Lenslow City before.

So Arold didn't directly attack the magic shield from the front.

The siege continued.

A large number of soldiers and swarms besieged Black Rock City, and a small number of them entered the attack area of the magic cannon, depleting the opponent's magic crystal reserves little by little......

"Marshal."

Half an hour later, a human general approached.

"Are you ready to arrange everything?" Arold asked.

"Yes, Marshal!"

The general replied quickly, "All the tank bugs are ready, having dug through a wide passage to the interior of Blackstone City, and they are now frozen outside the magic shield underground. Wait for your orders at any time, Marshal. ”

"How many tank bugs are arranged?" Arold asked.

"Fifty-six thousand eight hundred."

"Yes." Arold nodded.

"That's enough, let's start attacking the magic shield underground. I'll come later. ”

"Command!"

"Yes!" The human general quickly retreated, and quickly passed Arold's order to a Zerg hero who was responsible for controlling the Zerg army. It was the Half-Blood Insect King under Wang Chen......

……

Wow~~~~

In the underground space, a large number of tank insects also gathered in a newly excavated vast space. They crowded here, all spitting hot lava breath at the pale blue magic shield in front of them.

More than 56,000 tank bugs breathe lava together.

The scene was simply terrifying, and almost instantly, the entire underground space was illuminated by the fiery red light, as if a few small suns had been arranged in the depths of the earth!

The heat also spreads, heating the sealed underground space into a furnace.

If ordinary humans come here, they may be burned to death by the hot air in an instant!

But the tank bugs didn't care.

They have a thick shell that far surpasses the defenses of the human body, and they are naturally resistant to fire, and some hot gases can't help them.

The energy consumption of the Magic Shield also increases.

……

At this moment, on the ground, the officers in the black market city were also in an uproar!

"What's going on!"

"Magic shield. Why did the speed of consuming magic crystals suddenly increase so much? ”

"Check!"

"Hurry up and find out the specific reason!"

"Keep going like this. I'm afraid that in a few days, our magic crystal reserves will be exhausted...... "Some of the human generals who defended Black Rock City originally had so many super magic equipment and a large number of magic crystals. After the magic shield was raised, he already faintly looked down on the Zerg troops under Wang Chen's command. Also to the defeat was captured. Now the elite legion of the original Thorn Flower Empire, which is helping the enemy to fight his own family, disdains.

But at the moment...... They panicked!

The magic shield and the support of a large number of magic crystals are already the key to whether they can defeat the enemy at this moment.

But at the moment, this is the most critical thing. Something went wrong?

And how can they not panic!

Even some began to send urgent requests for help within the Empire.

Speed up the Imperial Empire's troops escorting magic crystals!

……

In the heat of the underground space.

Wow~~~~

A figure wearing heavy magical armor also appeared, with a straight body, a majestic complexion, and sharp edges.

This person is none other than Arold.

Arold also looked at the magic shield beneath Blackstone......

In almost every war fortress of the Thorn Flower Empire, this kind of magical protection system will be arranged underground, and even in normal times, the tank worm cannot penetrate the ground, and cannot enter the city smoothly.

Destroying this magical shield is also the only way to enter Blackstone City from the underground.

Otherwise, a large number of tank insects will dig through the ground of Blackstone City, and a large number of Zerg creatures will pour into the city, and the war will end in a moment, and it won't be so troublesome......

Call.

An ordinary and unpretentious heavy sword appeared in Arold's hand.

Anyone who knew him knew that he was good with a sword.

One-handed heavy sword.

And he never uses a sharp sword, his every move is wide open and close, full of violent power!

Arold casually raised his heavy sword with one hand.

After entering the legendary realm, he also began to gradually comprehend his own powerful sword moves!

At the moment, this is a real place.

And this magic shield, which has been scorched and melted by countless lava breaths, is his opponent at the moment!

"Sword ......"

"Collapse!"

Arold swung his heavy sword, which was so thick that Arold's arm was as slow as if it were holding a heavy mountain...... The heavy sword made a slow trace, and it also drew a series of pitch-black cracks in the void of the underground space.

"Broken!" He let out a loud shout, and the tip of the heavy sword in his hand slammed into the pale blue wall of light on the periphery of the magic shield!

At that moment, the entire already bright space seemed to increase its brightness by a few percent......

Thundered~~~~~~

The terrifying roar also spread along the attack point of the heavy sword in Arold's hand, and the large pieces of earth and stone on his body were directly blown away by the strong wind that was lifted, and the ground in Black Rock City trembled even more at this moment, and even cracks appeared in the walls of some low stone houses.

Some of the old stone barracks even crumbled and collapsed.

Some of the soldiers also screamed and dodged around!

The human generals inside Blackstone City were also in a panic......

Rumble!!!

There was a roar from the depths of the earth again!

Some buildings in the interior of Blackstone City fell down, and at this moment, the ground was cracked with terrifying scars, as if a desolate beast was rolling in the depths of the ground.

"General! Checkmate! The enemy seems to be attacking from underground! ”

"What are we going to do!" The herald shouted, waking up the supreme general defending the city......

It was a chubby guy named Cullens.

The title on his body is also a marquis, and when he launched a denunciation of Wang Chen in the territory of the Thorn Flower Empire, he was also the most enthusiastic group of cousins, and he belonged to the nobles who vigorously supported the crusade against Wang Chen! (To be continued......)
