The Invincible Overlord of Heroes.

Xu Lai did leave. He had no interest in hiding in the dark and watching the caveman perform monkey shows.

Not only did he leave, he also left very far away, and he even replenished his food and water in the meantime.

Unfortunately, he was stuck in traffic again, but this time he knew he would be stuck.

Because this place is on the map. It is clearly recorded on the map of Morrell's territory. There is a pass in the underground city, which represents the boundary of Morrell's territory.

The changes in underground terrain also follow certain rules.

Like Xu Lai, the dragon lich who built the city, he may not be very familiar with the underground terrain patterns, but the dungeon clan who have lived underground for a long time still has some summaries.

They can roughly guess which places may be closed in the future and which places will be reopened.

Therefore, in order to prevent their cities from being buried underground, they would build passes in dangerous areas where they believed accidents might occur, including areas that were extremely vulnerable to human harassment.

Xu Lai originally planned to force his way through the pass, otherwise there would be no need to bring so many Seraphim out.

But the obstacles we encountered this time were more troublesome.

It’s not that we are not confident in the military strength, but this pass is rather special in that there are no guards.

For a pass like this in a marginal area, if we send garrison troops here, not only will the garrison be unable to move, but they will also need to constantly transport supplies.

The key is that if there are too few defenders, it will be useless. If there are too many, generals or even heroes will be stationed there, otherwise they will be treated like monsters and suffer a great loss.

If there were only one or two borders, it would not be impossible to accept given the strength of the underground city.

The key is that the underground is very complicated, and Moril was reluctant to invest, so she simply built this unmanned pass.

There are only a small number of defenders at the pass, who are responsible for controlling the mechanisms, arrow towers, turrets, magic towers and traps on the pass.

Just now Xu Lai went to take a look and saw ten advanced arrow towers, ten advanced turrets and four wind, fire, water and earth, four elemental towers.

If Xu Lai forces his way in, his troops will be slowed down by the earth tower, frozen by the water tower, and damaged by the lightning of the wind tower and the fire of the fire tower.

In addition, the ten advanced arrow towers are equipped with large mechanical crossbows that do not require human control. They are driven by spells and mechanisms, and automatically aim and shoot. While the damage is terrible, the hit rate is not low.

On the contrary, Xu Lai doesn’t care much about the turret, which is quite scary to ordinary people.

This thing can fire hundreds of stone balls the size of a baby's fist at a time. It is used to deal with clustered infantry. For advanced units like Xu Lai, it can't even break through the defense.

Single attack, spells, plus group attacks, and it is an extremely durable pass with almost no manpower stationed, and there is no need to store too much supplies.

It is equivalent to gaining nothing from the battle. If we continue to fight, we don’t know how much troops will be lost.

Xu Lai didn't bring any catapults, and he didn't even have any long-range troops, so he would be attacked if he got close.

Even if a dozen Holy Light Knights can make the Seraphim invincible for two or three minutes, it is not easy to destroy these advanced arrow towers and spell towers with extremely high durability and city defense armor.

And he had tried it just now. The crossbows from the advanced arrow tower were enough to break through the defenses of Seraphim and Holy Light Knight.

In addition, there are lightning and fire spells. If you cannot break through the level in a short period of time, your side may suffer unnecessary casualties.

Therefore, after a brief attempt, Xu Lai gave up, mainly because there was no need to fight to the death with a pile of broken rocks and mechanisms.

Not only is there no benefit in winning, but it also wastes time. If there are casualties, it would be a huge loss.

There is another important reason why Xu Lai did not plan to force his way in.

There aren't many resources around here, but the underground town he came across was obviously well developed.

Xu Lai was basically certain that the owner of the dungeon should have a pass to enter and exit this level.

The only advantage of recruiting soldiers is that they will not be lazy, will be serious and responsible, and will not allow for even the slightest bit of slackness.

Recruiting soldiers will not be done through bribery, threats, etc. like ordinary people.

The bad thing is that recruiting soldiers is extremely rigid and only follows orders, without any possibility of compromise.

Therefore, as long as one gets the pass to the checkpoint, anyone can pass directly through.

So, after taking a walk around, Xu Lai came back to get the pass.

The caveman sent all the Medusas away, and there was no one guarding the guard tower, so he was unable to notice Xu Lai and others coming out from behind.

Xu Lai rubbed his ears helplessly and pulled hard on the royal warhorse which was also frightened.

This little thing might be considered powerful among the cavemen, but it was not even as tall as Xu Lai's horse leg.

The royal warhorse is an eighth-level warhorse. Even among a group of Holy Light Knights, it is particularly conspicuous, and it stands out even more among ordinary horses.

Even if this little thing is not as tall as a horse's leg, it is actually nothing. After all, even among ordinary people, there are very few who are as tall as a horse's leg.

But the sight of this terrifying warhorse raising its front legs was a little too terrifying.

The caveman was already screaming with fear, and as soon as the horse's legs were raised, the caveman fell directly to the ground, shitting and pissing himself all over the place.

Xu Lai looked at all this with disdain, and asked while suppressing his nausea:

"The checkpoint behind you is unguarded. You have the pass, right?"

The caveman's eyes rolled around, and just as he was about to say something to threaten this hateful human, a long knife fell at this moment.

With a click, the caveman was a hero after all. The equipment and treasures on his body were not top-notch, but most of them were mainly used to increase defense and life.

Jilong still had Xu Lai's ultimate offensive skill, but unfortunately this attack neither triggered a critical hit nor a lucky hit.

"Ah..." The caveman rolled on the ground in pain.

Xu Lai frowned in dissatisfaction. When the caveman's eyes rolled, Xu Lai knew that the other party was not holding back his fart, so he simply signaled Jilong, who was more clever, to kill the other party directly.

Anyway, if the caveman really has a pass, he would most likely hide it in his space backpack, and it would definitely explode after he died.

But if you kill someone with a knife, the dead person cannot speak, and it is somewhat embarrassing to leave him in a half-dead state like this.

Xu Lai waved his hand, signaling everyone to kill this guy quickly.

But I didn't expect something even more embarrassing to happen. The Holy Light Knight is a warrior whose defense is far greater than his attack. He usually charges with a lance, and the speed bonus is not noticeable.

At this time, you can just chop with your sword, but the damage is low and the attack speed is slow.

Even with Xu Lai's help, the opponent also had advanced defensive techniques, which was like cutting meat with a blunt knife, and the scene became extremely bloody.

Fortunately, there were many people involved in the attack, and each person used a sword, and they finally killed the caveman before the group of Medusas got close.

Xu Lai and his men were not afraid of Medusa's arrows, but there was a pile of stone statues standing not far away, and Xu Lai really didn't dare to let these Medusas get close.

For this reason, he didn't even send the Seraphim, for fear that if he was not careful, the Seraphim, who could only fight in close combat, would be petrified by Medusa.

After killing the cavemen, the Medusas instantly became wild monsters, and their morale was about to drop to zero. "A group of Medusa archers are shocked by your powerful strength and want to surrender to you. Do you agree?"

After hesitating for two or three seconds, Xu Lai chose to refuse, and once again refused to chase after these Medusas, allowing them to escape to the rear.

They killed other people, robbed their things, occupied their cities, and even recruited their troops.

These things sound very cool, but these half-human, half-snake creatures are too slow.

There is no way Xu Lai would slow down for these Medusas.

Moreover, bringing these Medusas with him would not increase his combat power much.

If he lacks long-range output, wouldn't it be better to bring the phantom shooters or even the phantom arrow saints at home?

However, if these Medusas were to be left behind and meet the people who were chasing Xu Lai, these Medusas without Xu Lai's blessing would most likely only become experience points for others.

The dead Medusa can only damage his morale. Even if he survives by chance, Xu Lai's morale will be lowered when he takes over these Medusas.

Even if he has the Angel Alliance, it will be useless because the Angel Alliance only protects friendly and neutral units, and Medusa belongs to the enemy camp.

"Pick up the things on the ground. We don't have time to dig up the heart of the dungeon. Let's pack up and get ready to leave."

The cavemen had a big explosion and things were everywhere, but at a glance, there didn't seem to be anything valuable.

Xu Lai picked up something that looked like a blue key, and after confirming that it was the pass to the rear pass, he left the other miscellaneous items to Jilong and the others.

He did not leave, but urged his horse, walked quickly to the stone statue of the woman, and sprinkled a bottle of petrification potion on her head.

The woman was not permanently petrified. Xu Lai sprinkled a bottle of petrification-removing potion on her and successfully rescued her.

The rescued woman still had a look of shock on her face.

Looking at Xu Lai who was so close, the woman was stunned and said, "Yes, you saved me?"

Xu Lai shrugged. Although he was the one who saved the person, he had no intention of thanking him. He even said bluntly:

"The caveman is already dead. Without Medusa to continue petrifying you, you should all be able to recover. It's just a matter of time."

The woman was stunned for a moment, but still said: "But if it were someone else, and they just pushed it away, we would probably have to stay underground forever."

“I don’t have much potion to remove petrification, so you stay and continue to watch them.

There is probably no one else in this city. Medusa and the cavemen have already escaped. You are safe for now."

"You, you still want to move forward, don't you want this city?"

Xu looked at her and said, "I don't have time to deal with it. If you want, go dig it yourself.

But I advise you not to follow me anymore, or you won’t have such good luck later on.”

If Xu Lai hadn't said anything, the woman wouldn't have dared to follow him any further. At this moment, there was no one around her to protect her, so how could she dare to go any further?

But the woman didn't want to let go of the man in front of her.

The woman gritted her teeth, suddenly pulled down the leather armor in front of her, which already had little fabric, and said:

"My name is Huaying. I have no way of repaying you for saving my life. What's your name, handsome boy?"

Xu Lai frowned and said coldly: "I still have a lot of petrification potions here. I wonder which one will be more powerful compared to Medusa's petrification ray."

After hearing this, Huaying quickly pulled up her leather armor.

If she was petrified in this state, she had no idea what the passing mercenaries and adventurers would think of her, she simply couldn't imagine it.

Xu Lai ignored the woman. He had done his best.

Ahead is the dungeon level. Even though Xu Lai has a pass, he cannot guarantee that he can pass it.

If this woman dares to follow him, she will definitely die.

But this woman's life or death is none of Xu Lai's business.

Xu Lai took the trouble to pour a bottle of anti-petrification potion, on the one hand out of pity as a fellow human being.

On the other hand, he took advantage of this good opportunity to test the functions of the various magic potions in his hands.

After cleaning up all the caveman's relics, Xu Lai threw all these things into the newly added space backpack.

This time, the space backpack has grown a lot, which shows that this guy has killed quite a few heroes.

After a short rest, Xu Lai led the team to continue on their journey.

When they got close to the pass, Roland, with the Holy Shield in hand, rushed out first holding the blue key.

With the help of Holy Shield and Holy Armor, Roland can be invincible for two full minutes. Even if he needs to negotiate in the middle, he has enough time to escape.

Fortunately, although Xu Lai and his team belonged to the Imperial camp, the guards recruited soldiers only recognized passes and not camps, and they actually let Xu Lai and his team in.

If this guy is not released, it will be really troublesome. Even if we use Doomsday Judgment, it will not have much effect on the building.

In the end, Xu Lai might only be able to summon earth elements or fire elements to destroy the arrow towers, spell towers and so on.

After passing this level, there will be basically no obstacles afterwards.

Although it is still a long distance to the destination, and we need to go through two or three underground cities along the way.

But now the entire underground kingdom is in a state of chaos, and the underground nobles fighting for power are taking every opportunity to divide up the territory left by Muriel.

In other words, no matter what Xu Lai did to the towns along the way, basically no one would come to cause trouble for him.

Therefore, it would be easy to deal with these cities if they were sensible. Xu Lai did not want to cause trouble.

But if they don't know what's best for them, Xu Lai doesn't mind giving them a Doomsday Judgment.

A large-scale fireworks show every day helps illuminate the dark environment underground, allowing them to see the light again, which is also a pleasant thing.

Moreover, after being equipped with the Hand of Fire, his Doomsday Judgment became more powerful, and even the range increased as the fire magic was upgraded to a high level.

The most important thing is that his level, which was difficult to increase, was rising at a speed visible to the naked eye because of this spell with a very large range and very high damage.

After releasing the Doomsday Judgment once in three cities, Xu Lai's level was raised by one level.

So, no wonder everyone in the game loves to play a mage. This kind of large-scale spell is really the best choice for killing monsters and upgrading.

Xu Lai has become addicted to it. If it weren't for the fact that this spell consumes a lot of mana, he wouldn't even want to leave. He would want to visit all the big cities underground. (End of this chapter)
