Lin Xuan rushed to the furnace of the Thunder Tower in a single step.

It's scorching hot here.

A dozen low-level warriors shovel coal here.

Although Xiaoling Mountain is a super secret realm, there are still a lot of low-level warriors.

Their jobs are basically in service areas such as catering and chores, and some are responsible for forging and pharmaceuticals.

If you want to recruit high-level warriors to do this kind of thing, you don't need to spend common currency, it must be the essence.

The Construction Division couldn't afford to recruit them, so they simply recruited some low-level warriors from outside.

At this time, these low-level warriors have been smoked with red eyes and tears.

But the coal is empty.

"The coal is out!"

"What should I do, there are still more than 20% of the lightning tower left, and I'm not full at all!"

"Let's run, we are low-level warriors anyway, even if the city wall is broken, we have nothing to do with us."

When Lin Xuan rushed to this place, the few low-level warriors had run away again, and only a few were left in a hurry.

Under their shocked eyes, Lin Xuan rushed directly to the furnace, picked up a blue object and stuffed it inside.

The few warriors shook their heads in despair.

"It's useless, in addition to coal, oil, and natural gas, it must be the golden items produced in the super secret realm to be used as energy. We have tried everything on our body just now," a fourth-order martial artist looked solemn, "I I threw a few pieces of my equipment in, but nothing happened."

Lin Xuan glanced at him, "Are you an operator of the Construction Division?"

"no."

"Then why are you working so hard, even throwing in the equipment to try?"

The fourth-order warrior sighed, "If the city wall is broken, there will be too many ghosts, and it will definitely be unstoppable. We low-level warriors have no one to protect."

"So, I tried everything around me as much as possible, just because we were closely related to the gathering place."

Lin Xuan nodded, "You are someone who can see clearly."

Those low-level warriors who escaped, as well as those high-level warriors who quietly retreated from the city, said something ugly, and they were all short-sighted.

The city wall was broken, and the entire gathering place was destroyed.

The way to ensure that the city wall is not broken is to activate all the lightning towers!

The No. 3 gathering place is dozens of kilometers away from the No. 2 gathering place.

There are very few seventh-order warriors who can escape to the No. 2 gathering place under the attack of ghosts at night.

"What did you throw in just now? Can it be used as energy?" the fourth-order warrior asked.

Lin Xuan threw an advanced observation technique on the lightning tower again, nodded and said, "Not only can, but it can be charged very quickly."

A thundering chalcedony actually provided 10% of the energy!

"One more, just fill it up!"

Lin Xuan threw another one inside.

The next moment, the lightning tower suddenly made a violent roar as if it was full of energy.

The warriors at the head of the city raised their heads in shock, and immediately shouted excitedly, "The lightning tower is full!"

The person in charge of the East City Wall was also very pleasantly surprised, "Nice job! Everyone relies on the lightning tower to shoot down all the ghosts!"

Those ghosts who rushed into the vicinity of the lightning tower and attempted to self-destruct, without even having a chance to self-destruct, were turned into blue smoke by the lightning that came with the lightning tower.

The design of Wanyougong also allows the Thunder Tower to filter humans by itself and only attack ghosts.

In this way, human warriors can unite under the lightning tower and rely on the lightning tower to quickly gain an advantage.

Boom boom boom!

A chain lightning hit the ground, a large number of ghosts were hit, and their bodies froze in place.

When the warriors saw this, they took the opportunity to act.

Even those warriors who had the intention to retreat rushed back when they saw this, and hurriedly threw their skills one by one into the city.

Boom!

The lightning tower shot a super-strong lightning chain directly down the city wall. Half of the ghosts within a diameter of 50 meters were killed and half seriously injured!

Those who were seriously injured were also blinded, unable to fight back, and soon died under the various skills of the warriors.

The fourth-order warrior heard the surprise shout from the city head, and was also very surprised, "It actually took effect?!"

He wanted to thank the young seventh-order warrior, but found that the other party had disappeared.

Lin Xuan turned on the wind and lightning, and quickly rushed to the other two lightning towers. Following the same method, he threw the two thundering stone pith into the furnace.

The two lightning towers were also filled with energy in a very short period of time.

The terrifying thunder light poured wildly towards the city!

When the person in charge of the East City Wall saw the sudden increase in power, he was a little surprised.

"Why is the power of this lightning tower stronger than usual? It's really weird."

At this time, Lin Xuan had already invested the thundering stone pith for the three lightning towers on the east city wall, and soon came to the person in charge of the east city wall.

"Apart from the east city wall, were the other city walls also attacked by ghosts' self-destruction?"

The person in charge of the East City Wall shook his head, "I didn't receive their help. It should be our side that was attacked like never before."

Lin Xuan was relieved.

"The reinforcements are here!"

At this time, the person in charge found that many warriors were coming from the other three walls.

The leader was Old Man Wu, who was in charge of registration at the entrance of the gathering place.

"We're here! Isn't it too late?! Huh?" Old Man Wu rushed up to the city wall with a big axe, but when he saw that the ghost attack had been beaten back, he was suddenly surprised.

"The lightning tower here can be charged very quickly? Did you rely on the lightning tower to beat the ghost back?" Old man Wu put away his axe.

The person in charge nodded, "Thanks to this warrior codenamed Shield, he didn't know what golden items he took out and put it into the furnace of the Thunder Tower, which accelerated the charging of the Thunder Tower and saved the situation before the entire line of defense collapsed."

Old Man Wu glanced at Lin Xuan in surprise, "I remember you, you are one of those brought by Old Li."

Lin Xuan nodded.

"What kind of golden items did you take out? Don't worry, the Construction Division will not forget your achievements. Tonight's military achievements will be counted for you." Old Man Wu said with relief.

"The thundering stone pith of the Falling Thunder Mountain."

Lin Xuan didn't want to hide it either.

The promotion of Luoleishan to a super-secret realm has spread in the entire construction department, and the items produced by Luoleishan are almost known to the warriors.

"It turned out to be Minglei stone pith, no wonder! This thing is indeed very suitable for use as fuel for lightning towers." Old man Wu nodded again and again.

"It's not just me, there are also some Minglei stone marrow provided by my friends." Lin Xuan pointed to Ye Yuqiu and others who were still seriously fighting ghosts on the city wall.

Old Man Wu laughed, "Okay! The people that Lao Li brought are really good! Don't worry, you won't lose any of your military exploits!"

He patted Lin Xuan's shoulder with relief, and turned around to inspect the other city walls.

The three lightning towers on the east city wall were in full operation, and they immediately exerted extremely strong lethality. The ghosts couldn't even get within ten meters of the city wall.

In the distance, the suture monster stared at the lightning tower viciously and glanced at it for a few times, let out a low roar, and first disappeared into the darkness.

After it left, the ghosts' fighting power was greatly reduced.

Although he was still attacking the city wall tirelessly, his previous high fighting desire was gone.

After an hour, all the ghosts that attacked the third gathering place were eliminated.

All the warriors let out a long breath.

There is quite a feeling of after a catastrophe.

However, in the post-war statistics, the casualty figures made many people silent.

14 civilian warriors died and 32 were seriously injured.

37 construction officers were killed and 11 seriously injured.

These are all real seventh-order warriors!

Especially the construction managers are well-trained warriors, but in order to protect the lightning tower, many people were buried under the self-destruction of ghosts.

A battle came to an end, and the person in charge of the east city wall arranged for a construction manager to be on duty at night, and the rest of the warriors dragged their tired bodies back to their residences.

On the way back to the residence, Lin Xuan and others inadvertently checked the bracelet.

It was found that their military exploits in Xiaoling Mountain had soared a lot.

Everyone got at least 2,000 battle credits.

Due to the amazing damage caused by the Pyroblast, he even gained 3,000 battle credits.

"Minglei chalcedony is really a good thing. It is very suitable as a fuel for lightning towers. It is estimated that the construction department will increase the intensity of excavating Cinglei chalcedony in the future." Yinhu said with a smile.

Everyone nodded.

At first, they only thought that Minglei stone marrow was the life-saving trump card of mage professionals who were good at lightning spells.

They didn't react until the person in charge spoke.

Isn't Minglei stone marrow a golden item with lightning properties! Just the right amount of fuel for lightning towers!

"Let's rest everyone, tomorrow we will continue to secretly investigate the abnormal situation at the No. 3 gathering place." Ye Yuqiu greeted the others and entered his room.

Lin Xuan and others also entered their respective rooms, took a shower, and lay down to rest.

After a long night, Lin Xuan didn't feel sleepy after a battle, so he simply checked the situation of the underground cave through Xiaoyan Snake's point of view.

When he focused on watching Xiaoyan Snake's perspective, he was stunned.

Hold the grass, what is this!

Looking at the sight of Xiaoyan Snake, this gloomy underground space is actually densely packed with ghosts!

These ghosts had empty eyes and numb expressions, and they just floated on the spot sluggishly, not moving at all.

The little rock snake appeared here, and was not attacked by ghosts.

Lin Xuan's scalp felt numb for a while~lightnovelpub.net~ This is a ghost hole, right?

Are there really so many ghosts in Xiaoling Mountain?

Lin Xuan simply controlled the little rock snake to crawl towards the ground.

First of all, he needs to know to what extent do these thousands of ghosts gather in the underground cave?

The little rock snake kept meandering towards the ground.

The ghosts encountered along the way became less and less, and in the end there were no ghosts at all.

After more than two hours of meandering, Lin Xuan finally saw the moonlight.

"At the speed of the little rock snake... those ghosts probably gathered at a depth of more than 1,000 meters underground."

"The closer you get to the ground, the fewer ghosts there are."

"Does the Construction Department know about the existence of these ghosts? Or, did they appear recently? It should have appeared recently, otherwise the Construction Department will definitely send strong men to clean it up."

The more Lin Xuan thought about it, the more wrong he felt.

This little Lingshan is too evil.

It was getting dark faster than before.

The ghost will suddenly explode.

There are a large number of ghosts gathered at a depth of one thousand meters underground.

A group of Tianzhu warriors and Tianzhu spies have infiltrated in, ready to destroy.

With so many factors coming together, it always feels like the ultimate explosion will someday.

"Huh? There is a voice?" Lin Xuan suddenly heard someone speaking through Xiaoyan Snake's perspective.

But it doesn't sound like Chinese at all, instead it has a strong curry flavor.
