The second round of the dwarven army's attack was not long in coming.

In this round of attack, John Sal opened a hole card that did not surprise Zhao Pan too much.

That's the cannon!

After seeing the strange weapons of yesterday, it is really not surprising that the other side can take out the artillery.

In the previous round of siege battles, the opposite side did not directly push out the cannons, probably because they were afraid of the three-bow bed crossbows they deployed on both sides of the mountain wall.

However, after yesterday's battle, half of the mountain walls on both sides were blown up by the dynamite packs of the opposite balloon soldiers, weakening the firepower of the Beishan Fortress.

John Sal generously opened the hole card of the cannon.

At the same time, presumably to protect against the sniping of the elven archers, the cannon was surrounded by large shield soldiers, almost forming a tank formation, leaving only one muzzle outside.

From a distance, it really has a bit of a tank.

Amid the roar of artillery fire, a new round of fighting began again! The heavily armored dwarven hoplites covered the dwarven musketeers and hurried towards the North Mountain Fortress.

Faced with such a situation, Zhao Pan, who was standing on the wall, saw the move, and quickly issued an order while letting the defending troops on the wall suppress it with long-range firepower......

"All lightning mages, second-order thunderstorm skills are ready!"

Under the rapid chanting of the mage troops, the thunderstorm technique, which was a second-order attack spell, had already been pinched in their hands.

Seeing the moment the dwarven heavy armored infantry on the opposite side broke into their attack range, Zhao Pan waved his hand......

"Attack!!"

After this order, a large number of thunderstorm spells suddenly smashed towards the dwarven heavy infantry below.

After the thunderstorm burst out, the frantically raging electric current immediately caused the dwarven hoplites who had invaded outside the city to let out a terrible scream, and then fell to the ground heavily.

This situation made John Saar, who was commanding the battle in the rear, feel tight, and Zhao Pan, who was standing on the wall, already showed obvious joy on his face.

"And so it was!"

In the previous battle to defend the city, Zhao Pan, who was standing on the wall, had been observing the opposite side.

In the face of the heavy infantry wrapped in thick armor, the effect of attack spells such as exploding fireballs, gale bullets, and flying stones did not seem to be particularly good.

But only this thunderstorm technique seems to have caused obvious damage to the opposite side, and it can even be said that the effect is outstanding!

Before this, Luo Ji obviously didn't deliberately teach him the physical reaction that metals can conduct electricity, mainly because the current civilization of the Ten Thousand Worlds does not need this kind of knowledge for the time being, but at this moment, Zhao Pan discovered this through his own observations.

He may not know how this works, but as long as he knows that lightning spells are useful for heavy infantry soldiers, he will be fine!

"The thunder mage continues to perform the thunderstorm spell, all the elven archers, replace them with lightning arrows!"

The issuance of a set of orders directly caused the violent current to rage on the battlefield.

John Sal, who watched this time, also had a straight heartbeat.

The heavy infantry unit that he was proud of was actually planted on that metal armor? Defeated by the opposite magic class in attributes?!

With such a dense attack frequency, he really hadn't encountered much of it on the battlefield of the Black Iron Rank.

The screams of the dwarven soldiers were now drilling into his ears.

Before he had time to think about it, John Sal hurriedly ordered his dwarven musketeers to suppress the opposite wall.

In the midst of a dense series of gunshots, the suppression of the dwarven musketeers played a certain role and bought him time to think.

At this moment, John Sal is swaying the scales of pros and cons in his heart.

This invasion war, if he insists on fighting, is obviously fought.

Because according to his experience, it is impossible to cast a spell attack like this endlessly.

Once the mage class runs out of mana, it takes a long time to recover, and they can no longer provide effective combat power in the rest of the battle.

As for the magic arrow with attribute attack, although he had not seen it before, it could not be a bargain no matter how he thought about it, it was a precious military material, and the quantity was definitely limited.

In other words, as long as it is consumed, he has a chance to win.

However, the price paid during this period will inevitably be a little excessive.

To pay this price for a yodel Senko who doesn't like each other?

John Sal would have been happy to have ghosts.

But if you just withdraw like this, the big boss of the alliance is a little difficult to explain.

Suddenly, John Saar's mood became a little irritable.

"Fire! Keep firing for me!! ”

The power of their dwarven cannons is obviously beyond doubt, after all, it is the talent of the race, and the destructive power caused by the cannonballs is even stronger than the cannons of the civilization of the Ten Thousand Worlds.

In the roar of artillery fire, the pressure on the defending troops was also not small.

Seeing an opportunity, John Sal retreated decisively, bringing the battle to a temporary end in a situation of non-concessions.

After the battle, looking at the devastated fortress city wall, Zhao Pan's face was full of solemnity, and he hurriedly called the goblin engineers over and asked them to carry out urgent repair work on the city wall.

On the other side, John Saar, who had withdrawn to the camp, also made up his mind after briefly counting the casualties of his army.

"Hemp eggs! Just this one, after fighting this invasion war, it can be regarded as giving an explanation to the bigwigs in the alliance, and after that, Lao Tzu will not be involved! ”

After making up his mind, John Sal couldn't help but wonder how to deal with the lightning magic attack on the other side.

As a modern person, he naturally knows that the key to this lies in the conductive properties of metal armor.

But what can he do? In a moment and a half, where could he go to find armor as an insulator?

Although it is possible to fight a war of attrition and use up all the mana of the mage on the other side, the price is really painful.

As his thoughts flickered, his eyes swept over the bare trees outside the camp, and John Saar, who seemed to have thought of something, slapped his thigh violently......

"Go and cut down all the big trees I can find nearby!"

The movements of the dwarven camp reached Zhao Pan's ears at the first time, making his brows furrow slightly.

"Large-scale tree cutting? What is the other party trying to do? ”

Obviously, in a fundamental sense, Zhao Pan, who is still an ancient person, cannot understand the approach of a modern player in a short period of time.

"Keep watching, confirm their follow-ups, and report back to me as soon as possible." ...
