In the Rat King's lair, Zeng Yizhou moved forward cautiously.

He has gone back to change his breath several times, and searched three passages, but he couldn't find any trace of the rat king.

'The rat king must know that I am here, and it is estimated that I have moved to other places. ’

Zeng Yizhou guessed in his heart.

The rat king's sense of smell is very keen, and he must have known about his arrival long ago and transferred it in advance.

Otherwise, it is impossible to find the trace of the rat king after searching for so long.

In addition, he has already searched three channels, which took a lot of time.

This time is also enough for the rat king to burrow out and move to other areas of the underground labyrinth.

'Forget it, let's wait for Zhou Hong and the others to get the oxygen cylinder, it's not a problem to find it like this. ’

Zeng Yizhou shook his head secretly, then quickly returned to the starting point.

Now whether or not the Rat King can be found, at least the Rat King's lair won't run here.

It's a bit of a credit for reporting the situation in the Rat King's lair.

Zeng Yizhou was extremely fast and returned to the original passage in just one minute.

At this time, Zhou Hong and the others hadn't returned, so he decided to sit here and wait until Zhou Hong and the others brought the gas masks and oxygen cylinders over before exploring.

'Anyway, this Rat King's lair was the first I found! ’

Zeng Yizhou was quite proud.

With this shot, he not only successfully found and injured the rat king, but also found the rat king's lair.

Made many firsts.

These are the capital he can be proud of.

...

on the ground.

While Zeng Yizhou was complacent alone, Lu Heng and He Sicheng were very busy.

Lu Heng was busy contacting the base city and asked the base city to send a large helicopter to transport the rat king back.

And He Sicheng took out the first aid suit and bandaged his left shoulder.

Time passed by minute by minute.

About ten minutes later, there was a sudden sound in the distance.

Apparently a helicopter came over.

Lu Heng was quite surprised that the reinforcements came too quickly.

Did this helicopter just happen to pass by here?

Or, this helicopter happened to be on a mission nearby and was temporarily ordered to carry the Rat King?

...

inside the helicopter.

Xing Zhan was wearing a military combat uniform and sat on the seat.

After the college entrance examination, he completely ended his teaching career and enlisted in the army to become a military warrior.

Today, he and his college friend Tan Zhenxing, who is also a military warrior, came out to carry out the mission together.

As a result, when he was about to go back after completing the mission, he suddenly received an order from his superiors to let them come and ship a rat king.

"Which two martial arts students caught the rat king?"

Tan Zhenxing wondered.

In the order I just received, it was only said that two martial arts students caught the rat king, but they did not say who they were.

"The Rat King has the strength of the fifth level, and the average student must be helpless." Xing Zhan guessed: "So, it must be those outstanding students who can make it to the rankings."

"Who would that be? Zeng Yizhou? Chu Xuefeng?" Tan Zhenxing looked confused.

In Jiangnan City, there were only Zeng Yizhou and Chu Xuefeng who could rank at the top of the rankings.

So, is it these two?

However, both of them have fifth-level strength and are not allowed to enter the underground labyrinth. It seems that they have to be excluded.

"Don't guess, just wait and see."

Xing Zhan turned his head and said to Tan Zhenxing.

The helicopter continued to fly, getting closer and closer to the destination.

Tan Zhenxing turned to open the hatch and looked into the distance.

"I saw it. It's on that hill over there."

Tan Zhenxing turned his head and said to Xing Zhan.

"Oh?" As soon as Xing Zhan heard this, he also stuck his head out, "I'll take a look."

As a result, Xing Zhan was stunned on the spot.

Because it was Lu Heng who was standing on the top of the mountain.

"How could it be Lu Heng?"

Xing Zhan was very surprised.

Hearing this, Tan Zhenxing was stunned, and then asked, "Is that the student you took out on the search and rescue mission last time?"

"Well, it's him." Xing Zhan replied.

Tan Zhenxing was surprised: "couldn't it be that he caught the rat king?"

"It doesn't look like it." Xing Zhan hesitated.

Just seeing Lu Heng on the mountain now does not prove that the rat king was caught by Lu Heng.

Xing Zhan guessed that Lu Heng might just be helping others.

After all, with Lu Heng's strength, he couldn't defeat the Rat King no matter what, let alone capture the Rat King alive.

At this time, Tan Zhenxing said again: "I saw the rat king, in that mountain col."

Xing Zhan immediately followed his line of sight when he heard the words.

Sure enough, the Rat King was half on the ground and half in the soil.

And not far from the rat king, sat a student.

The student was dressing the wound by himself.

"He Sicheng?!"

Xing Zhan exclaimed.

Hearing this, Tan Zhenxing said speechlessly, "Lao Xing, don't tell me that he was your student before."

Xing Zhan turned his head to look at him and said, "You guessed it right."

"what?!"

Tan Zhenxing punched Xing Zhan's shoulder and said with a smile, "Lao Xing, you can do it, the students you teach are all strong!"

He had met Lu Heng but not He Sicheng, so he instinctively thought that He Sicheng was a former student with great strength. Lu Heng successfully caught the rat king with the help of He Sicheng.

Also, He Sicheng was injured, but Lu Heng was not injured, which can be proved to some extent.

On the other hand, as soon as Xing Zhan saw Tan Zhenxing's expression, he knew that he was thinking about it, and reminded: "He Sicheng and Lu Heng are in the same class, and they both entered Jiangnan Wuda this year."

"what?"

Tan Zhenxing was stunned on the spot.

At this time, the helicopter had already flown to the top of the mountain and began to land slowly.

When Lu Heng on the top of the mountain saw it, he immediately rushed down the mountain.

Now that he is wearing the Qi energy armor, he is much stronger than a third-level warrior, so he descends the mountain extremely fast.

When the helicopter hovered directly above the Rat King, he also rushed to the side of the Rat King.

"Mr. Xing."

Lu Heng recognized the person who jumped from the helicopter at a glance.

The first one to jump off was Xing Zhan in military uniform, and the one behind was Tan Zhenxing, who had a relationship.

At that time, before Xing Zhan took him out to search and rescue Chen Mingzhe and others, he went to Tan Zhenxing to borrow two robot dogs.

On the other side, He Sicheng also stood up from the ground and greeted Xing Zhan.

"Lu Heng, Sicheng, you caught this rat king?" Xing Zhan asked impatiently when he came up.

"It should be..."

He Sicheng turned his head and glanced at Lu Heng as he spoke, a little unsure.

After all, he was already here as soon as he woke up, and he had no idea what happened before.

Only Lu Heng knows these things.

When Xing Zhan and Tan Zhenxing saw He Sicheng looking at Lu Heng, they also looked at Lu Heng, expecting Lu Heng to give an answer.

Lu Heng quickly explained to the gazes of the three of them, "I can't explain a few sentences about this matter. I'll talk about it when I go back."

"Row."

Xing Zhan didn't say much, and turned to check the situation of the rat king.

The most important thing now is to quickly transport this rat king back to the base city, and other things have to be put later.

"The rat king is still alive for the time being, but his condition is not very good, and he may die at any time."

Opposite Xing Zhan, Tan Zhenxing took the lead in completing the inspection, got up and said to everyone.

"Okay, then hang it up quickly and transport it back."

Xing Zhan started to drag the rat king and drag the rat king out of the vertical passage.

Lu Heng and Tan Zhenxing also immediately came to help, and cooperated with Xing Zhan to drag the mouse king.

He Sicheng stepped back to make room for the three of them.

Soon, the rat king was dragged out.

Xing Zhan walked to the edge of the vertical passage and asked, "What's under this?"

"It's the rat king's lair," Lu Heng said.

"Huh? You actually discovered the rat king's lair?" Tan Zhenxing said in surprise.

Lu Heng hurriedly explained, "I'm not too sure, I'm just guessing."

"Okay, let's hang the rat king first."

Xing Zhan looked back, and together with Tan Zhenxing, tied the rat king with ropes, ready to hoist it under the helicopter and transport it back.

Lu Heng immediately came to help.

Moments later, the rat king was tied tightly and hung under the belly of the helicopter.

After doing all this, Xing Zhan said to Tan Zhenxing: "Old Tan, you and He Sicheng go back first and bring the Rat King back to the base city. Lu Heng and I will go down to check to see if it is the Rat King's lair. "

"Okay." Tan Zhenxing nodded in agreement.

Seeing this, Lu Heng hurriedly asked, "Mr. Xing, do you have any gas masks on the plane?"

"Yes, what's wrong?" Xing Zhan asked in confusion.

"There's poisonous gas down here. If you don't wear a gas mask, you have to hold your breath." Lu Heng said.

When Xing Zhan heard this, he thought about it and asked, "Did you come up from below?"

"Yes." Lu Heng nodded.

"Then you are holding your breath?" Xing Zhan asked again.

"right."

Lu Heng nodded again.

Up to now, he can only lie that his ability to hold his breath is particularly strong, otherwise many things cannot be explained.

After all, as a martial artist, as long as you exercise well, your breath-holding ability can far exceed that of ordinary people.

Lu Heng did the math, and it would take at most four minutes to complete the whole process in a straight line if the passage that found the Rat King went through the Rat King's nest all the way to the surface.

With the help of Qi Neng armor, it is possible to hold your breath and carry a person for four minutes.

Because the Qi energy armor support itself does not require much power, the demand for oxygen is very small.

You must know that even ordinary people who are not warriors can hold their breath and dive in the water for a few minutes.

In the case of wearing Qi energy armor, the actual amount of exercise and the energy expended are not much different from diving.

Nature can do this too.

Xing Zhan glanced at Lu Heng, then turned to Tan Zhenxing and said, "Old Tan, throw two gas masks down after going up."

"Good Le!"

Tan Zhenxing agreed, and then helped He Sicheng to climb the rope ladder.

The two quickly returned to the helicopter.

Later, Tan Zhenxing found two gas masks and threw them at Xing Zhan.

"Go back quickly."

After Xing Zhan caught the gas mask, he waved to Tan Zhenxing.

Tan Zhenxing also waved his hand.

The helicopter quickly turned and flew towards the east.

Xing Zhan and Lu Heng both looked away.

Xing Zhan threw one of the gas masks to Lu Heng and said, "Put on... Wait, where's your combat helmet?"

It was only then that he remembered that neither Lu Heng nor He Sicheng were wearing combat helmets.

I just thought about transporting the rat king back quickly, completely ignoring this detail.

"I lost it." Lu Heng replied, and then added: "Mr. Xing, let's talk about this later. Let's go down and have a look first."

He had already figured out how to explain the whereabouts of the combat helmet, but he couldn't say a word or two.

On the other hand, when Xing Zhan saw Lu Heng say this, he didn't ask any more questions.

In fact, he just asked curiously, and had no other meaning.

After all, Lu Heng is now a student of Wuhan University and has nothing to do with him.

In other words, even if Lu Heng's combat helmet is lost, he doesn't need to ask him. His own teacher from Wuhan University will investigate.

"Come on, let's go down."

Xing Zhan put on a gas mask, walked to the vertical tunnel, and swiftly arranged the ropes for abseiling.

Afterwards, the two used the rope to return to the tunnel below.

"Is it just ahead?"

Xing Zhan asked.

"Well." Lu Heng nodded and led the way.

The two walked quickly, and soon came to the huge underground cave.

Until then, Lu Heng had time to take a good look at the environment here.

He turned the searchlight fixed on his chest to the brightest and searched carefully.

Beside him, Xing Zhan was also using the headlight to observe the surroundings, and while observing, let the camera on the combat helmet record all this.

"Rainbow grass!"

After some searching, Lu Heng really found rainbow grass.

Densely packed, there are about a hundred plants.

It grows right in the middle of this underground cave.

At this time, Xing Zhan noticed Lu Heng's actions. Seeing that he was staring at the rainbow grass, he asked, "Lu Heng, are you going to pick these rainbow grasses?"

The last time the two came to this underground labyrinth together, Lu Heng picked ten rainbow grasses, so Xing Zhan guessed that Lu Heng might be thinking about rainbow grasses again.

When Lu Heng saw Xing Zhan's question, he didn't shy away, nodded and said, "Well, I've been researching otherworldly plants recently. I just saw a lot of silver frost flowers on it, and I'll pick some up later."

Rainbow grass and silver frost flower both come from another world~lightnovelpub.net~ Therefore, Lu Heng used the research of otherworldly plants as an excuse to avoid Xing Zhan's association with highly poisonous plants.

"Why are you studying this?" Xing Zhan asked curiously.

Lu Heng thought for a while and said, "Mr. Xing, we will one day counter-attack the other world. It's always good to study more about the other world."

When Xing Zhan heard this, he immediately nodded and said, "That makes sense."

Seeing that Xing Zhan was no longer entangled in this matter, Lu Heng suddenly breathed a sigh of relief.

He thought in his heart that next time someone else asks, he will use this reason as a prevarication.

"Go, look forward."

Xing opened his mouth and said, walking forward.

But at this moment, there was a rush of footsteps in one of the passages, and it seemed that many people were running towards it.

"Does anyone else know about this place?"

Xing Zhan turned his head and glanced at Lu Heng curiously.

Lu Heng shook his head blankly, expressing that he did not know.

After he and He Sicheng entered the underground labyrinth, they had been looking for the rock-devouring rats to kill. Later, they suddenly found that the rock-devouring rats were escaping en masse. They thought they encountered some danger, so they also ran away.

As a result, he accidentally broke into a cave full of poisonous gas, woke up from a coma, and ran into the injured rat king.

Therefore, Lu Heng didn't know what happened during the coma, and naturally he didn't know the existence of Zeng Yizhou, Zhou Hong and others.

Deng Deng Deng!

Five people ran out of the passage one after another.

Lu Heng took a closer look and found that it was Zhou Hong, Zeng Yizhou and others.

In an instant, he vaguely guessed something in his heart.

On the other side, Zeng Yizhou stopped involuntarily after seeing Lu Heng and Xing Zhan, his face full of surprise.

"Why are you here?"

Zeng Yizhou asked.
