The two of them had been climbing up for ten minutes.

These ten minutes also happened to be the longest action time of that specially customized tear gas grenade.

It stands to reason that even the largest rat will have to finish the calf after being smoked by this deadly tear gas.

However, facts have proved that some things really have a vitality comparable to that of Xiaoqiang.

Just as Li Yan encouraged Tie Qinglan to hold on, a loud squeak came from the cave again.

The cry was rapid and high-pitched, as if it had a bit of panic and fear.

Soon, at the entrance of the cave, the corpse of the large giant rat that had been shot through the head by Li Yan with an arrow was suddenly knocked out, fell vertically and fell into the mouth of the giant python and became food.

Then, in the cave, a group of giant rats suddenly rushed out.

The giant rats looked like they were being chased by something, so they were a little panicked.

At first, the group of giant rats still knew how to jump hard, and after seven or eight of them landed on the trunks of the giant trees one after another, the remaining giant rats were like dumplings, crackling and all planted in the blue lake hole.

And the seven or eight giant rats that landed on the trunk of the tree soon found the cliff where Li Yan and Tie Qinglan were, and rushed over in a swarm.

The rats themselves are extremely good at climbing, if it weren't for the fact that the individual of this group of rats was too big and affected their speed, otherwise, they would have taken down Li Yan and the others by climbing wild vines on the cliff.

But even so, seven or eight giant rats were soon climbing up a few relatively thick vines.

According to the current speed, I am afraid that it will not take a few minutes for them to catch up with Li Yan and Tie Qinglan.

Li Yan soon noticed that there were seven or eight giant rats chasing after the vines below, and when he looked up at Tie Qinglan, he smiled and said, "Qingluan, the rats are coming, if you don't climb quickly, you will be bitten on the ass!" ”

As soon as Li Yan said this, Tie Qinglan immediately glanced down.

When she saw that the seven or eight rats were catching up at a rapid pace, the almost exhausted power in her body suddenly surged out again, and her speed increased by more than two times in a flash.

Li Yan was below, holding the wild vine with one hand, and with the other hand, he directly pulled out the tactical scimitar, looked at a tree vine next to him, and then stabbed it fiercely!

Syllable!

The Tactical Scimitar was originally intended to open the way and was extremely sharp.

This knife went down and directly cut off the tree vine, and the two giant rats on the tree vine rolled and fell down directly.

But before they could fall halfway, the two giant rats had already grabbed the other two adjacent vines and climbed up again to chase them.

Seeing this, Li Yan couldn't help but get more and more angry.

The big man was chased by a group of rats and fled, which is too aggrieved.

Thinking of this, Li Yan simply cut off everything that could be reached around him, Wild Vine, in one breath!

In this way, most of them have finally been solved, and there are still three that are far away from him, so they can only go for the time being.

"Brother Yan, there are still the last five meters, it's at the top!"

Tie Qinglan's voice came, which made Li Yan's heart happy, and he immediately inserted the tactical scimitar into the scabbard, and then climbed quickly.

The distance of five meters does not sound like much far, but at some point, these five meters will really drain all of a person's physical energy!

When Tie Qinglan struggled to climb onto a raised ledge platform, her arms trembled violently.

The blood could not flow to the arm, resulting in a complete loss of strength in the arm, which was very uncomfortable.

As Li Yan's figure also climbed up smoothly, after seeing Tie Qinglan still rubbing his arms, he immediately ordered: "Shake it hard, let the blood flow to your arms!" Fast! ”

Tie Qinglan nodded immediately when she heard this, and shook her hands hard.

Soon the blood flowed again, and the arms gradually gained sensation and strength.

Creak!

At this time, the three giant rats had already rushed up.

Seeing this, Tie Qinglan directly pulled out her tactical scimitar and rushed forward!

Puff puff!!

Three knives in succession, the three giant rats were directly split open intestines and stomachs, and then roared hoarsely!

Roaring, just to vent the sobriety of the rest of your life after the catastrophe, is an excellent way to relieve stress.

Li Yan looked at Tie Qinglan's appearance, and the two couldn't help but look at each other and smile, and then they couldn't stop laughing.

After laughing for a long time, the two of them were often relieved, and then carefully looked at the surrounding environment.

The platform in front of you was a protruding ledge, not the very top, and, looking up from here, it seemed that it was not a hundred meters high, and there were at least eighty meters to get to the top.

On the inner side of the ledge, there is a crack in the mountain that is more than one person wide, and it looks like some kind of naturally formed cave.

There is no other way out of this ledge.

Although there are still a lot of vines in the upper part, most of them are very thin, and they fall off when you pull them.

And even if they don't fall off, the two of them can't continue to climb up.

The second half of the cliff is upside down, at least more than 30 degrees of inverted angle, with professional mountaineering equipment to climb is very difficult, relying on a few wild vines, it is even more difficult.

The two of them could not continue to venture either, they stood beside the ledge, looking at the lake cave below, on which the dragon-like figure was still circling and swimming.

At the entrance of the cave on the right, a black python bites two giant rats in its mouth, biting dead in the air.

This way of swallowing is completely different from that of an ordinary python.

They tear their prey apart and swallow it raw.

Ordinary pythons or venomous snakes are all swallowing their prey into their stomachs.

They are more of a bloodthirsty beast.

"Brother Yan, I now understand a little why these giant pythons can survive here."

Tie Qinglan retracted her gaze and watched Li Yan continue to speak word by word.

"The huge number of giant rats here provides plenty of food for those pythons, and the right temperature around here provides the best environmental conditions for the pythons to grow."

"Here, the python may have no natural predators, so it grows unscrupulously, so that it grows bigger and bigger."

"And that giant tiger also relied on preying on the pangolin in the water after the heavy rain and when the flood waters receded......"

"Every creature here has found its own way of survival and even evolution in this unique ecosystem."

Tie Qinglan's words made Li Yan nod frequently.

"yes, the dragon...... Actually, it's also a giant snake, but it shouldn't be considered a python! ”

Li Yan looked at the dragon-like black giant snake as he spoke, and then turned his head to look at Tie Qinglan: "Do you remember the little snake we met next to the camp of the arrow rat squad on the way here?" ”

"I remember, you said that kind of snake is called the Nocturnal Dragon!"

When Tie Qinglan said this, she suddenly realized.

Li Yan also nodded with a smile on the side: "You're right, the big guy below is a nocturnal dragon, but, from an individual point of view, it should be regarded as the dragon king of the nocturnal dragon!" ”

"It's a pity, I lost my phone, otherwise I would have been able to use my name to name the dragon king."

Li Yan smiled, then waved his hand, collected his mind, and looked at the black crack.

In his eyes, there was a bit of coldness and excitement!
