Lu Heng and He Sicheng followed the team all the way down.

In addition to building a steel fort to protect this place, a very large hole was dug inside.

There is a series of steps made of steel at the entrance of the cave. As long as you walk down the steps, you can walk all the way into the underground labyrinth.

After following the team into the cave, Lu Heng and He Sicheng looked around for a while.

It was found that there are many staff members in the cave to maintain order and provide necessary services.

From this, it can be seen that the rock-devouring rats in this underground labyrinth are indeed a big threat to the base city.

Otherwise, why are you so inspiring?

"Come here first and download the topographic map to your wrist computers."

"The maze below is very easy to get lost, remember not to turn off the camera on the helmet after entering, and check the topographic map more."

The staff shouted over there and asked people to download the topographic map.

This place is very important, so there are strong people who have gone deep into the maze and drawn the topographic map of the maze.

However, since this underground labyrinth is very vast, the topographic map is not complete.

But for these junior warriors present, this topographic map is enough.

Because those really dangerous places, with their strength, are completely dead, and there is no need to guide them to the past.

When the improved Qi energy armor can be mass-produced, they will be arranged to go deep into the dangerous area to exterminate the rock-eating rats in the depths of the labyrinth.

Lu Heng and He Sicheng came to the table with the computer and downloaded the program for the map of the labyrinth under the guidance of the staff.

After downloading, the two returned to the steps leading to the underground labyrinth and went down the steps.

At first, the underground passage they reached was full of people, but as they went deeper, they dispersed, and soon only the two of them were left.

However, Lu Heng always felt that someone was following him.

Of course, this doesn't matter, as long as it's not a powerful monster following him.

"Lu Heng, after you put on the Qi Neng armor, you should have a strength close to the third level, right?"

He Sicheng asked as he moved forward cautiously.

"More than that, don't forget, our Qi energy armor was carefully adjusted by Dai Jun for us."

Lu Heng reminded.

He Sicheng suddenly said, "Yeah, I almost forgot about this."

After speaking, he asked again, "Lu Heng, how much strength do you have now?"

"It looks like level three, maybe a little bit stronger." Lu Heng replied.

He Sicheng heard the words thoughtfully and said: "Then I should be much stronger than the third-level, and killing the third-level rock-devouring rat is completely no problem."

As he spoke, he calculated, "Ten points for a second-level rock-devouring rat, and twenty-five points for a third-level rock-devouring rat."

"Then as long as you kill one hundred and twenty third-level rock-devouring rats, you can collect 3,000 points and change to a fourth-level battle armor."

The defense performance of the fourth-level armor is much better than that of the third-level armor.

If you can wear a level 4 battle armor, your chances of surviving against a level 4 rock-devouring rat will be greatly improved.

"Lu Heng, I think it can be done like this. Let's find a way to get a set of level 4 battle armor and level 4 weapons first, and then go to the depths of the maze to kill more rock-devouring rats."

He Sicheng suggested.

Lu Heng said: "Then you have to kill two hundred and forty third-level rock-devouring rats, or 600 second-level rock-devouring rats. I'm afraid it is not that simple."

"Look, I haven't touched a rock-devouring rat along the way."

Lu Heng said and looked around.

squeak-

As soon as Lu Heng's voice fell, there was a slight creaking sound from the depths of this passage.

He Sicheng lowered his voice and said, "Look, did you come here without saying it?"

He was full of joy and fighting spirit.

Lu Heng discovered that He Sicheng was far more eager to fight than himself.

Perhaps as he himself said, people can only explode their potential in adversity, so they have to experience more severe battles.

"Come on, let's kill that rock-eating rat."

He Sicheng gently drew out his sword and said to Lu Heng.

"Well." Lu Heng also pulled out the knife.

The two of them use the same sword, but the swordsmanship they learn is different.

Lu Heng learned the saber-shattering technique created by Liu Zongshi when he was young, while He Sicheng learned the Xunying knife technique which was repeatedly improved by several senior warriors.

The Saber-breaking method is more comprehensive, integrating attack and defense, while the Xunying Dao method is known for its speed and strength, focusing on offense.

Also, Lu Heng's swordsmanship was picked with the help of Coach Wu.

But He Sicheng's knife technique was chosen by himself.

Just like how he has repeatedly tempered his bones, internal organs and even his brain without the teacher's objections.

This knife technique is also a must for him to learn after seeing it at a glance, and the teacher has to agree.

An outstanding student at the level of a scholar like him has willful capital, and sometimes teachers have to compromise.

far behind.

Zhou Hong waved his hand to signal the four to stop, then lowered his voice and said, "I heard movement."

"Have they encountered a rock-eating rat?" the girl among the five asked.

Zhou Hong nodded slightly and said, "It should be."

"Then after this battle, they should realize the danger here." A boy said.

"Yeah." Zhou Hong replied: "After they recognize their strength, I will go to persuade them, and I should be able to persuade them to go back."

"Then what if they are injured by the rock-eating rat?" the girl worried.

Zhou Hong said: "It's okay, let's go over now and help them depending on the situation."

"Okay, then let's hurry." The girl urged.

"Walk."

Zhou Hong said no more, and waved his hand for the four to follow.

front of the channel.

Lu Heng and He Sicheng walked forward cautiously and hurriedly towards the place where the sound came from.

They don't know how timid the Rock Rat is, so they don't know if they will scare the other side away.

But thinking about it, based on his own physical strength, he shouldn't make the rock-devouring rat alert.

You know, one of the two of them is in the early first grade, and the other is close to the second grade.

Not to the second level.

One step, two steps, three steps...

As the distance got closer, the life detector began to issue an early warning, showing that there was a moving target 100 meters ahead.

After walking for a while, the light from the headlamp finally shone on a rat-shaped creature about fifty or sixty centimeters in height.

Apparently it's the Rock Rat.

At this moment, the rock-eating rat was facing away from them, constantly gnawing at the rock and soil on the wall.

"This thing must know we're here."

He Sicheng said softly.

"But he is not afraid at all." Lu Heng replied softly: "It seems that as long as our physical strength does not exceed this thing too much, it will not be afraid of us."

In this way, it is easy to deal with, if you find that the rock-devouring rat can just rush up, you don't have to worry about the other party escaping.

"rush!"

He Sicheng gave a light drink and strode forward.

Seeing this, Lu Heng also ran quickly, and the two of them rushed towards the rock-devouring rat.

Sure enough, even if the Rock Eater heard their fast running, they didn't bother to pay attention to them.

Probably in its view, these two "weak" humans are nothing to be afraid of.

Just as Lu Heng and He Sicheng rushed forward, Zhou Hong and the others had already arrived not far behind them.

"No, that rock-devouring rat is level three."

Zhou Hong exclaimed.

The girls in the team hurriedly urged: "This is going to be bad, let's go up and help them!"

In their opinion, the strength of Lu Heng and He Sicheng will not exceed the second level, so wearing the Qi energy armor will definitely be below the third level.

Because the mass-produced Qi energy armor can only make people have the same strength as a third-level warrior, even if it has full power output.

Normally, warriors below the second level would not be able to withstand full power output.

Therefore, Zhou Hong and others judged that the strength of Lu Heng and the two must not be third-level.

They even thought that after Lu Heng and He Sicheng put on the Qi-neng armor, it would be hard enough whether they were level 2 or not.

"Quick, it's going to be troublesome if you're one step too late!"

A group of five people ran at full speed and rushed to save the two.

At the same time as they started, Lu Heng and He Sicheng were running faster and faster, rushing towards the Rock Rat at a faster speed.

Because they found that the Rock Rat showed no signs of escaping, there was no need to hide their strength.

Also, there was a bit of a rivalry between the two of them, wanting to see who could kill the Rock Rat first.

bang bang bang-

Heavy footsteps echoed in this passage.

The two got closer and closer to the Rock Rat.

"It's mine!"

He Sicheng shouted violently, rushed forward, and took the lead.

squeak!

The Rock Rat finally realized that something was wrong, turned around quickly, and rushed towards Lu Heng.

Its instinct told it ~lightnovelpub.net~ that the two humans that it killed were far weaker than it, so there was nothing to be afraid of, just kill the weaker one first.

"Good come!"

Lu Heng was overjoyed.

He Sicheng wanted to take the lead, but instead drove the Rock Eater to his side.

You can't be polite this time.

Clang——

Lu Heng followed the charge of the Rock-devouring Rat and slashed towards the opponent's head.

Unlike humans, monsters cannot use tools and can only rely on their own bodies to fight.

Those with agile bodies mainly rely on dodging, and those with thick skin and flesh can ignore the opponent's aggressive offensive.

Rock-devouring rats clearly belong to the former category.

So after this knife was cut out, the Rock-Eater could only dodge by dodging, or else it would have to die on the spot.

Unfortunately, the rock-devouring rat had just underestimated Lu Heng's strength, and the momentum was too strong, making it too late to hide now.

Bang!

Lu Heng's sword made a muffled sound on the rock-devouring rat's skull, and he chopped its head in half on the spot.

One hit kill.

Behind Lu Heng.

Zhou Hong and others stopped involuntarily when they saw this scene.

They knew in their hearts that they underestimated these two freshmen.

Obviously, these two people have the strength of third-level warriors after wearing the Qi energy armor, and they are not weaker than them.

"Are the freshmen of this class so fierce?"

Zhou Hong was greatly surprised.

But just when he was surprised, a messy sound came from the depths of the passage.

And it gets louder and louder at an extremely fast rate.

It seems that there are countless rock-devouring rats running towards this side.

Immediately afterwards, everyone's life detectors issued warnings one after another, and the sound of dripping in the earphones continued.

"so much?!"

Everyone was shocked.
