In the early morning of the next day, as Li Li expected, countless blue lion flags were set up in the distance, and Zolant led the troops to move forward.

Li Li stood at the top of the city wall with a [rusty spear] in his hand.

As if it was determined that the Invincible City would not send troops to meet it, 10 [giant catapults] with rollers were pushed out first.

"The other party is standing alone at the head of the city, isn't there some ambush?"

[Cavalry Captain] said worriedly.

The reason for this is that this kind of posture of not being defensive at all is too rare in siege warfare.

"The invincible city is only empty and walled, so it's not unusual to dare to come out to fight."

In the information that Zolant has, there is no record of large-scale troop dispatches in the Invincible City.

All kinds of weird and terrifying lost creatures have been mentioned by many people.

When attacking Shen Qiaoyin, he also obtained a lot of corpse specimens, but even if he returned to the main city, he couldn't analyze which faction this creature belonged to and what kind of weakness it had.

However, in front of the systematic cavalry formation, Zolant thought that those demons were not worth mentioning at all.

"Why don't you move forward?"

Li Li, who was wearing goggles to observe the situation, saw that the other party's [giant catapult] suddenly stopped, and said in confusion.

At this time, more than a dozen soldiers armed with shovels came to the front of the array and began to dig on the spot.

In this way, he dug all the way, and finally when he walked forward about thirty meters, a soldier suddenly stepped into the air and his body fell into the ground.

The rest of the soldiers approached the collapse and tentatively began digging at its edge.

After a while, an entire area of ground around it collapsed downward.

Zolante slowly walked to the edge, glanced into the pit, and shouted with a smile: "I'm really sorry, Lord Li Li, Han Song has already informed us of your natural ability, so we have already taken precautions about this collapse trap." ”

Li Li put his hands on the city wall, looking incredulous.

Zolant was very satisfied with this reaction.

"From here, continue to check on both sides and find a safe section of the road where the giant catapult can pass and let me know."

Zolante explained, and then rode leisurely and turned away.

Ten minutes later, Zolant glanced at him.

Seeing that the excavation and detection of the road surface had caused two-thirds of the road surface in front of me to collapse, I immediately noticed something unusual.

"What's the situation?"

Zolant rode quickly to the edge of the pit.

"Uh.... Report to Leader Zorant, it seems that the road ahead is full of deep pits, and there is no area for troops to pass through. ”

The soldier holding the shovel reported.

The corners of Zolante's mouth twitched.

I thought to myself what kind of routine this is, just dig a deep pit in front of my main city, don't you even leave a passable road?

Wait a minute, the Invincible City is under siege, and it doesn't seem to need a road...

Zolant seemed to understand Li Li's layout.

Since the city gates can't get out, what else do you need to do with the road, just dig all the deep pits.

"Chief, what now?"

[Cavalry Captain] asked tentatively.

At that moment, a wail of pain came from the pit.

"Help me, I'm not dead!"

Zolante looked over and turned out to be the first soldier to fall into the pit because of the temptation to dig.

Just now, because the scope of the collapse was not large, even if the sun shone in, it would be dark.

Now the inside of the pit is completely exposed, and the details are naturally very clear.

"This pit is just over ten meters away.... If there is a way, immediately organize the engineering troops, dig down from the edge of the earthen pit, and get a slope that can be passed through by the troops as soon as possible. ”

Zoolrant was very excited to issue the order.

He believes that Li Li's thinking is correct, but he ignores a very important key point in the actual implementation.

If a large area of pits is dug in an area, as long as the troops descend to the same plane and can still move as usual, the pit is the same as if it was not dug.

Of course, too low terrain will put the troops at a disadvantage, but in terms of range, Zolant does not believe that there is a farther than the [Giant Catapult] in the invincible city.

As long as the troops advance to the right distance, the invincible city can only be beaten passively.

Watch as the [engineering troops] begin to dig slopes and open the way for the large army.

Li Li put his hands on the city wall, and his face was incredulous.

When the time came to noon, the downward slope was dug up, and the [Giant Catapult] advanced again.

However, when the 8th [Giant Catapult] came to the bottom of the pit, there was a boom!

The bottom of the pit collapsed again, and the 8 [giant catapults] and the soldiers responsible for carrying them all fell into the pit on the next level.

Zolante above looked at the pitch-black pit in the pit, and the whole person was stunned.

He looked up at the top of the invincible city, Li Li put his hands on the city wall, still looking incredulous.

"Can't you just change your expression!!"

An angry Zolant roared.

"I just like this expression to get in the way of you, but I still want to thank Lao Tie for sending the catapult."

Li Li waved his hand in thanks.

"Come on, bring all the people who went to dig and probe below just now, and all of them will be executed on the spot!"

The Giant Catapult is not Zorant's own unit, but has been borrowed from his lord Rune.

Lost 8 in one go, even if this battle is won, there is no way to go back and explain.

The excavation and probe soldiers pleaded one after another, making it clear that they had probed the depth of the soil layer as required.

Zolant frowned slightly, and went to observe the collapse edge of the pit in the pit, and found that it was not like the first layer, the soil layer was only one square thick, but two squares thick.

It was all arranged, I was calculated...

Zolant's gaze was gloomy at first, and then a little cold light.

"Immediate execution!"

After Zolant finished arranging the instructions, more than a dozen heads fell to the ground.

After thinking for a long time, a new order was issued: "All cavalry advance in a dispersed array."

The cavalrymen who listened to this order were a little confused.

The scattering of the forward array is to dodge area attacks, such as when facing a mage who unleashes a large area of magic.

But when the cavalry set foot in the pit, it soon understood the intentions of the leader Zolant.

The purpose of the scattered formation is not to dodge attacks, but to reduce the weight carried by each dirt area.

It has been proven that it takes 8 [giant catapults] to collapse the soil layer at the bottom of the pit.

Then as long as there are not too many cavalry in the same area, it will not cause a collapse.

"Looks like Zolant is a lot smarter than I thought, let's fight."

After Li Li finished speaking, Shen Qiaoyin and Bai Haitao behind him set off together, descending from the stone steps at the top of the city wall, and entering the inside of the city wall with a thickness of 260 blocks.

There were only 2 [Giant Catapults] left, and they quickly advanced to the designated position.

Li Li knew that the top of the city wall with the best view could not stay any longer, so he immediately chose to evacuate.

Rumble! Rumble!

Round boulders crashed into the walls, smashing into cobweb-like cracks.

However, the inside of the city wall was still a wall, and there was no sign of it being destroyed.

More than 400 [elite cavalry] charged to the bottom of the city wall and began to slash with swords.

However, if a weapon shatters up to 5 [Stone Blocks], it will be cleaved and can no longer be used.

For the walls of an invincible city with a thickness of 260 blocks, it is completely impossible to pose a real threat.

However, since you can become an [Elite Cavalry], you naturally won't stop there.

Many cavalry began to relay and cut down the city walls, and together they opened a passage.

It is certainly unrealistic to want to be wide enough to pass through on horseback, but as long as they can make a gap large enough for one person to pass through and fight their way into the city, there is nothing to stop them.

However, to the surprise of the cavalry, only 20 Stone Blocks were smashed forward, and the obstruction of the wall disappeared.

In its place was a small square hall with eight forks in the road that could only be used by one person.

"Let's go ahead."

"I don't move in front of me, how can I go!"

"Don't squeeze the ones in the back!"

....

In the narrow passage, the complaints of the [elite cavalry] were soon heard.

The [elite cavalry] in the square hall was annoyed, so they had to hold a torch in one hand for lighting and a long sword in the other, and choose a fork in the road to pass.

After the first cavalryman walked forward a few dozen meters, he felt as if something was on his side just now.

So he took two steps back and looked sideways at the wall to the left.

He was right, this place was different from the nearby stone wall, not only was there a huge hole carved out, but there was also a [brown bear] standing in it.

"Ahh Yes! Yes! ....”

In fear, the [Elite Cavalry] roared and swung a sword.

Dressed in iron armor, Xiong Da raised his arm to block, knocked down the [Elite Cavalry] with a bear fist, and then dragged it into the dark hole.

Fall into a deep pit with one foot, be attacked by various beasts that suddenly appear, or be swallowed by the [Man-eating Flower] fixed to the ceiling....

Under the successive screams, the faces of the [elite cavalrymen] waiting to enter the fork in the road became more and more ugly.

Zolante had just heard that the walls were not all stone, and he was quite happy.

It is believed that the walls of the invincible city seem to be magnificent, but in fact, they are only the color of the strong and dry outside, and there are not so many stones filled in them.

When I heard the report that the cavalry had been ambushed and ambushed by various trap beasts, I realized that something was wrong.

Set traps in your own walls....

Zolante gritted his teeth, not to mention this tactic, he had never even heard of it.

After thinking about it, he still decided to let the troops withdraw first.

He can accept the loss of troops, but this kind of aggrieved death is too demoralizing.

Not long after, the [Siege Commando Captain] came to Zorant.

"The walls are higher this time, do you have confidence?"

Zolant asked tentatively.

"Rest assured, Chief, the siege assault troops will live up to your expectations."

"Then go, if I can take the top of the city wall, I will give the siege assault soldiers the first credit."

Zoolrant gave assurances.

At the core of the city wall, in the combat command room with a wall thickness of 30 squares, Li Li was closing his eyes in front of the square table.

"Hmm... When will I be used?"

Wang Qiang asked tentatively.

"Wouldn't it be nice to have an experience here?"

Li Li asked puzzled.

"Haitao and Qiaoyin both went to the labyrinth below to kill the enemy, I'm a little embarrassed to just rub the experience."

Wang Qiang scratched his head and said.

"When the catapult doesn't throw stones, it's time for you to strike."

As soon as Li Li's words fell, the tremor caused by the boulder smashing suddenly stopped.

"Next, it's the difference between victory and defeat."

Li Li said, picked up the [Rusty Spear], rode a level 18 [Corrupt Blade Mantis] on the side, and quickly returned to the top of the city wall.

At this time, the place has been bombarded by huge boulders, and at a glance, it is full of sunken arc craters, like the surface of the moon.

Click! There was a metal crisp sound, Wang Qiang looked over and realized that it was a metal hook claw hanging on the edge of the city wall.

Click! Click! Click....

More hooks followed at the same moment, and a dozen [siege assaults] wearing leather armor were the first to climb up.

The level 18 [Siege Commando Captain] saw that the enemy lord was also there, and he took the brunt of it.

Before he could get closer, there was a dense buzzing sound of wings around him.

The main force of 180 [Corrupt Blade Mantis] flew to the top of the city wall.

With such a huge disparity in the number of enemies and friends, the [Siege Assault Captain] knew that he must not fight hard, and hurriedly retreated to the edge of the city wall.

Because their first task is not to assassinate or fight head-on, but to protect the hooks and ropes used to climb the walls, and create opportunities for other ground troops to climb up.

So a tragic offensive and defensive battle began.

Siege Assault Soldiers were constantly being killed, or they had no way to retreat, falling from the edge of the city walls.

But there are more and more hooks hanging from the edge of the city wall.

Some [Siege Assault] will also release two ropes at the city when they find an opportunity.

"No wonder you say it's the key to victory or defeat...."

Wang Qiang was stunned.

Zolante's troops were unable to get through the city walls, so the focus of the attack shifted to the top of the walls.

Once lost, no matter how many floors the walls extend outward, they will be meaningless.

Li Li not only saw through this layer, but also grasped the timing of the attack very accurately.

If the Siege Assault Soldier wants to climb the city wall, the Giant Catapult must stop throwing.

Of course, Zolant also knew that this was the key to victory or defeat, but he didn't expect Li Li's reaction to be so fast.

"Attack with all your might!"

Knowing that he couldn't wait any longer, Zolant shouted, rode his horse and began to lead the charge.

Under the siege of the [Corrupt Blade Mantis], the [Siege Assaults] were killed one after another, and the area on the edge of the city wall they occupied was rapidly reduced.

However, there are more than a hundred ropes that can be climbed down, and they are not at all possible to be cleared in a short time.

"Li Li, can you let the blade mantis let it out, I want to go in... What about people? ”

Wang Qiang was expressing his willingness to participate in the war, but saw that Li Li was nowhere to be found.

When he turned his head, he saw that Li Li had run to a very backward position, and was violently scraping the ground with a pixel [iron pickaxe].

Wang Qiang ran over to inquire about the situation, and a pixel [iron pickaxe] flew to his feet.

"It's too deep, come and help."

Li Li urged.

"What is buried too deep?"

Wang Qiang asked.

"Poison swamp frogs, because they can't be deployed on the city wall in advance, and they must appear immediately when the battle is urgently needed, they can only be protected with blocks first."

Li Li explained while quickly picking the pickaxe.

"Then why don't you bury it a little shallower?"

"I miscalculated, overestimated the destructive power of the giant catapult, and I thought that the average height of the top of the wall would be broken by at least ten squares after the bombardment."

Li Li sighed and said.

Wang Qiang stretched out his hand and said, "Bring me another pickaxe?" ”

"yes, you're a berserker by talent, and you're good at dual-wielding."

Li Li's eyes lit up, and then he threw out another [iron pickaxe].

Bite! Bite! Bite! While! While! While!

The two of them began to dig the ground frantically on the city walls.

In the [Siege Assault Soldiers] who fought to the death, Zolant with a sword flew out.

Immediately after, more [Elite Knights] climbed onto the city walls.

"Li Li, are you ready to die! I...."

Zolante was in a hurry to kill Li Li when he learned the exact news that Li Li was at the top of the city wall.

It can be seen that Li Li is actually plowing the ground, and he is still digging very energetically, and he doesn't know what expression to do for a while.
