The air-conditioned green phosphorus fire burned on the stone slope below the fortress, which largely hindered the Imperial army from piling up the stone slope.

The stone slope has been piled up nearly 30 meters high, and the towering fortress is conservatively estimated to be 35 meters high, and the difference between the stone slope and the fortress is not more than 5 meters.

It is these five meters that have become a wall of heaven, and the temperature of the green phosphorus fire produced by the shattering of the green phosphorus fire flask is extremely high, not to mention the human body, even steel will be melted into molten iron.

Although the green phosphorus fire burned for a short time, about ten seconds before dissipating, the goblins on the fortress kept dropping green phosphorus fire incendiary flasks to stop the Imperial army from continuing to advance.

With the cooperation of the green phosphorus fire, the dwarves on the fortress controlled the 'city protection heavy wheel crossbow' to carry out a round of volleys, and the imperial soldiers under the fortress suffered heavy casualties, they were slaughtered without doing anything, and it was impossible for flesh and blood to rush through the green phosphorus fire.

To make matters worse, the rocks on the slope began to melt under the scorching green phosphorus fire, turning into a dark red liquid, which is the magma mold.

The situation of the Imperial Army is very bad, it can neither rush forward nor retreat, the Imperial Army has more than 80,000 dead and wounded, and retreating like this will cause a permanent blow to morale, and there will be no need to fight the war after that, unless a new batch of soldiers is replaced.

Legion Commander Carlos stood in front of the green phosphorus fire, watching the melting stones.

Sou~

A bullet was fired at Carlos, who slashed a sword in his hand, the bullet split in two, and he had forgotten how much of it had been broken.

Carlos, as the captain of the Imperial side, the contractor of the Apocalypse Paradise certainly has thoughts about him, and the reward for killing Carlos is extremely rich.

Carlos didn't even look at the contractors of Apocalypse, he just stared at the melting stones.

"Should... Almost, it cost 90,000 gold pounds, and if those alchemists still want to keep a low position in the empire, they will not provide inferior products. “

Carlos's gold list is the largest denomination currency in the empire, and 1 gold list can guarantee all the expenses of a family of five in 1 month.

A few days before the start of this war, Carlos applied to the Empire for a batch of special materials, which the Empire could not officially produce, and could only be purchased by the Alchemy Association.

The Alchemy Society was established in the territory of the Empire, but in order to obtain war materials from the Alchemy Society, the Empire needed to pay gold coins, even in times of war.

If those alchemists are provoked, not to mention the various alchemy items and demons they invented, once the relationship between the two sides breaks down, those alchemists don't mind moving their headquarters to the tribe's rule, the tribe will definitely welcome it.

If the power doesn't work, you can only buy it, but fortunately, the Alchemy Association is very knowledgeable, and the imperial military buys materials at a 6% discount, and the royal family buys the cost price, which gives the royal family enough face.

Before the start of this battle, Carlos had already thought that there would be the current situation, he had been fighting with the Tribal Alliance for too long, how could he not know the temperature of the opponent's 'green phosphorus fire'.

Since Carlos has adopted the current strategy, it means that he must have a way to deal with it, he can make the soldiers sacrifice, but he will not let the soldiers die in vain.

The height of the stone slope under the fortress dropped rapidly, from the original thirty meters to about ten meters high, and the red-hot magma slowly flowed down, and the high speed of the stone slope was lower.

A kilometer-long lava slope was formed under the fortress, which was almost an impenetrable line of defense, and the Imperial side was quite cocooned and bound to itself.

On the fortress, the minotaur Amster frowned, he couldn't figure it out, he couldn't figure out why Carlos, who had always been difficult, used such a stupid strategy? Judging from the current situation, the Imperial side will not be able to attack the fortress at all, and if this one-sided slaughter continues, within an hour, the Imperial army will have a large-scale rout.

Amster's guess was inaccurate, it didn't take an hour at all, the current Imperial army had begun to be unstable, and if it weren't for Carlos's scene in the front line town, the Imperial army would have fled.

The Imperial soldiers began to slowly retreat, and although the soldiers knew that the situation on the battlefield was precarious, the one-sided slaughter was unacceptable to them.

In the middle of the imperial army, Su Xiao retreated a magazine, he had already sniped more than fifty dwarven crossbowmen, sniping this special type of troops, and his combat achievements rose rapidly, but unfortunately, those dwarf crossbowmen learned a lot after a large number of casualties, except for the necessary aiming when firing crossbow arrows, they all hid behind the 'city protection heavy wheel crossbow' at other times, and easily did not show their heads.

Su Xiao pulled the trigger, and a newly emerging dwarf crossbowman was headshot. As soon as the Dwarven Crossbowman fell, five bullets, an arcane, and three bows flew near the headless corpse of the Dwarven Crossbowman, and his rangers were already rushing to kill the enemy because the Dwarven Crossbowman easily did not show his head.

Su Xiao's shooting speed was not slow, but it was not without opponents, and one of his own mages was not slow to shoot, and the opponent had killed at least thirty dwarven machine crossbowmen.

Through the mirror, Su Xiao saw the large magma slope under the fortress, he really wanted to rush to the fortress, there are many special troops on the fortress, if he can get close to these special troops, this war is over, and the 'Holy Oak Branch' is basically in hand.

In the current situation, it is obviously impossible to rush to the fortress, even if Su Xiao's physical strength attribute is very high, but he does not dare to resist the magma, the temperature of ordinary magma is between 700 degrees ~ 1200 degrees, and the magma under the fortress is roasted by green phosphorus fire, and there is a trace of green in the orange red, and the temperature is higher than that of ordinary magma.

Su Xiao was very puzzled, in the last battle, he had experienced the power of the 'Green Phosphorus Fire Burning Bomb', the 500-point strength counterattack shield was burned through in less than 4 seconds, if it wasn't for his speed fast enough to rush out of the green phosphorus fire burning area, he would have been burned to death.

This is the battlefield, if Su Xiao is not cautious enough, he will also die.

Carlos should know the power of the Green Phosphorus Fire Bomb, why did he choose this strategy?

Just as Su Xiao was observing the magma through the scope, he suddenly noticed a fist-sized red pentagram array floating on the surface of the magma.

The pentagram was fleeting, and if it weren't for Su Xiao's good eyesight, he wouldn't have noticed the pentagram circle with a similar color to the magma.

"Pentagram? Magic? ”

Su Xiao frowned and pondered, trying his best to recall the appearance of the magic circle, and drew it with his fingers on the ground beside him.

Soon, Su Xiao restored the appearance of the magic circle.

"It's not a magic circle, there are too many breakpoints, and the magic can't be circulated, it's more like ...... Alchemy? ”

That's right, Su Xiao feels that this thing is like an alchemy array, not a magic circle, although the alchemy array is similar to the appearance of the magic circle, but the alchemy array is a number of points operating alone, not a whole like the magic circle.

Why does the alchemy array appear in magma? A masterpiece of goblins?

Su Xiao stood up, he suspected that a lava giant would jump out of that magma at any time.

Grunt, magma boiled, the goblins on the fortress were the first to notice the anomaly, and their leader, the goblin inventor, rushed forward to carefully observe the changes in the magma below.

"Stop, stop throwing green phosphorus flasks."

The goblin inventor seemed to see something unbelievable.

"Carlos, this miscellaneous, hot and cold exchange alchemy array, and this kind of area, how many alchemists can create such a large-scale chain alchemy array, the problem should be those stones, the scheme."

The goblin inventor jumped straight to his feet, and he actually lost in alchemy.

"Everyone, get ready for a white-knuckle fight."

The goblin inventor's shrill voice rang out, and the dwarves and orcs near him were puzzled.

"Amster, gather your men, Carlos is going to lead someone to kill."
