"Then why don't you try it with alchemy engineering equipment first?" said with a frown: "Counting those supported by the mentors, we now have more than a hundred magic siege vehicles and alchemy ballistae, see if we can destroy a section of the city wall." ”

"I think it's okay, it's better to try it first, even if you can't beat it, you can get to the bottom of it, so that you can make the next siege plan. The Knight of Light agreed.

"Then let's fight, don't talk nonsense!" Overlord Flower said directly.

"Hmm!" the cursed man nodded, and with a wave of his hand, his successive siege machinery units immediately began to move forward.

Seeing this, the others were not to be outdone, and immediately let all their siege vehicles and ballistas start.

There were about one hundred and sixty or fifty in total, ballistas and engineering vehicles, gradually approaching the city walls.

In order to protect them, the Four Heavenly Kings also placed two two-hundred-person mage regiments from behind, which was enough to protect their safety.

In addition, they also had 5,000 wolf cavalry on their left and right flanks to suppress the formation to prevent Emperor Shitian's side from attacking these precious and vulnerable siege equipment on the city wall.

At a distance of about 3,000 meters from the city walls, they arranged all the siege equipment in a straight line, and then they planned to start the attack.

But at this moment, suddenly the opposite line of defense was full of fire, and then I saw rocket launchers, like meteors, to say the least, there must be hundreds.

Obviously, Emperor Shi Tian's side would not let them attack the city wall at will, so he would strike first.

However, when the Four Heavenly Kings saw this, none of them panicked, but instead showed disdain on their faces, not worried at all.

Sure enough, there was no need for them to give an order, and the two mage groups in front of them took action, making a few random gestures at will, and not seeing two very large magic protective shields, covering all the siege equipment like a heavenly dome, let them be firmly protected.

Not to mention a hundred rocket artillery, even 1,000 and 10,000, you can't imagine that you can hurt these siege equipment.

It is precisely because of this that the Four Heavenly Kings are so fearless and do not worry about the safety of siege equipment at all.

However, at this time, something suddenly happened that they were completely unexpected.

I only heard a bang, and the ground under all the siege equipment suddenly collapsed, and more than a hundred siege equipment, none of which missed the net, all fell into a huge crack.

With a tooth-aching sound of steel deformation, and a dull thumping sound, all these siege equipment were scrapped.

Seeing this scene, the four heavenly kings who were originally flat and eight books were about to explode, and they didn't even care about their own safety, so they hurriedly rushed over to check.

It didn't matter, but it almost them off.

It turned out that a huge chasm had been dug here long ago, 50 meters wide, 50 meters deep, and 2,000 meters long.

On the head is a layer of stone slabs reinforced by spells, and there is no problem when you usually walk by, but if Emperor Shi Tian uses a mechanical pull ring to detonate some pre-placed bombs, all the stone slabs will collapse, and then let the siege equipment on it fall down.

The so-called magic siege equipment, in fact, is made of enchanted wood, or steel siege equipment, because the body is too large and bulky, so it is relatively fragile, any strong man, aimed at the key parts of the smash can be smashed.

Not to mention letting them fall from a height of tens of meters, it is even more impossible to preserve them intact.

Especially those key keel parts, they were directly broken apart, and there was no possibility of repair.

In other words, before the battle broke out, all the siege equipment on the side of the Four Heavenly Kings was scrapped.

Seeing this scene, the Four Heavenly Kings trembled with anger and were furious.

The cursed man scolded angrily: "Emperor Shitian, this damn bastard, how could he dig a pit here in advance?

"This guy is so cunning, it's all the besieging side digging tunnels, how can the defending side dig tunnels first?

And Overlord Flower simply scolded: "This guy is really treacherous, he must have known that we would attack the city wall with siege equipment, so he deliberately dug a pit and waited for us, and even used rocket artillery to cover when he was trapping people, attracting the attention of all mages." ”

"Yes!" The Knight of Light also cried and laughed: "We are obviously a chess match, we shouldn't let the two mage groups shoot together, if only one mage group makes a move, then the other mage group can release the levitation technique when something happens, and save our siege equipment." But it's a pity, it's too late to say anything now, we have been completely calculated by Emperor Shitian!"

"Damn, is this guy really so smart?" said the cursed man with a frown, "How did he know that we were laying siege engines here?

"Hehe, of course it won't be in vain!" the Knight of Light smiled bitterly: "He always has a way to force our siege equipment to come to this ditch!"

"How do you force us?" asked Overlord Flower curiously.

"Actually, it's very simple. The Knight of Light explained: "If our siege machine is too far forward, it will attack violently, and even send men to make the illusion of a sortie, forcing our engineering machinery to retreat until it reaches the ditch. And if our siege equipment is too far behind, he will defend with all his might, and put on an indifferent appearance. In this way, in order to give full play to the power of the siege equipment, we will push the siege equipment forward. ”

"Oh, when you say that, it seems that he can really control the position of our siege equipment, and he can always pit us!"

"It's a pity, we're still too careless, if we let the mage check the battlefield in advance, we won't end up like this!" Overlord Flower said helplessly.

The Knight of Light pursed his lips disdainfully, "What you said is light, seeing that the war is imminent, you let the mage waste his magic and mental power to check what is below the ground?

"This~" Overlord Flower was suddenly speechless. Under normal circumstances, the two armies in the underground world face each other, and they are all fighting hard with a knife and a gun, and no one has ever dug a pit in advance and waited for someone to jump.

It can be said that Emperor Shitian's trap this time can be regarded as a precedent.

But then again, it is very difficult for others to dig such a big trap, and only Emperor Shitian, with enough earth-based cultivators in his hands, can create such a big trap in a short period of time, and he does it under the noses of the enemy without knowing it.

In fact, this trap was dug for only two or three days, and it was deliberately dug by Emperor Shi Tian against the opponent's siege equipment.

The person who did it was an earth monk, who used the earth control technique to dig a tunnel from here, and then slowly dug out such a large trap pit.

Even if hundreds of earth cultivators were dispatched, it took a day to barely complete it.

And they didn't dare to use any magic traps, for fear that the spell fluctuations would alarm the mages above.

Therefore, all the bombs are set up, and the mechanical rope detonating device is also used.

Although the power of the earth bomb is small, it is enough to blow up the stone slab on it, and the key is that this thing does not have any magic fluctuations, even if a mage walks on it, he will not be able to detect it. It can be described as the best weapon for mages.

After suffering such a big loss, the Four Heavenly Kings were also helpless for a while.

The milk bully couldn't help frowning and said: "The ones who just fell down are not only the siege equipment, but also the nearly 1,000 technicians who control the siege equipment, and they can't be trained in a short time." ”

Siege equipment, especially magic siege equipment, is more complex to control, especially the aiming system, which requires a certain mathematical foundation and long-term training to control.

And although there are many more such talents than mages, they are not considered to be the goods that can be seen on the street after all.

Anyway, the loss of more than a thousand people was enough to make the Four Heavenly Kings feel tricky, and it was not easy to reassemble so many control technicians.

The Knight of Light frowned and said, "The siege equipment is gone, why do you need a technician?

"What about this big pit?" said the milk bully, frowning.

"Use spells to fill in, damn it, this time it's really a big loss!" The Light Knight said helplessly: "Not only did we lose the siege equipment, but we also had to consume the magic power of the mage, fortunately, it was still during the tide of magic power, otherwise, our loss would be even greater!"

Others, you look at me, I look at you, and in the end, I can only nod helplessly and agree.

Because this pit is so big, if it is not filled by the soldiers of the army without the power of magic, it will probably take at least several days to do it.

However, Emperor Shi Tian is stronger than a day by day, and the four heavenly kings are stationed here, and the daily material consumption is astronomical, they can't last long at all, and they can't afford to waste time.

So, with the order of the Four Heavenly Kings, the two mage groups in front of them immediately cast earth-based spells, shaking the big pit down, and then smoothing out the place that went straight up and down, making the big pit something similar to a riverbed.

In this way, the follow-up troops can drive directly over without the help of any other items.

It's just that the terrain here has been affected after all, and the ground is also potholed, so when you walk on it, your travel speed will be affected a lot.

But that didn't matter anymore, when the mages had spent hours finally completing the project.

The Bright Knight said solemnly: "The three of us will each send 5,000 people, Overlord Flower, you will send 10,000 people, all of them will become cannon fodder troops, test the defense strength of the city wall!"
