In Han Du's eyes, the leopard is no longer an animal, but a very important member of his Blue Sky Expedition, with the same status as a human.

Just when Han Du was secretly anxious, he noticed that a dark shadow appeared in the corner of his eyes, which was above the stone wall where the leopard was, and it looked like a small space.

There was a light in his eyes, because when he saw it clearly, he saw that it was not a small space, but a small passage that stretched out very long.

This small passage is supposed to have been formed naturally during the formation of the cave, it is not very high, and people can only crawl in it, but it extends far on both sides, and it looks like it is a thousand meters long.

Han Du thought that he could use this small passage to help the leopard get out of trouble, but the leopard couldn't jump through that small passage at the moment.

He left the cover in front of him and walked back a few dozen meters to a stop, intending to climb from here into the small passage above.

In this situation, Han Du thought of the second expedition prop he got, the invincible climbing hammer.

He tried to extract the invincible mountaineering hammer in his heart, and there was a metal hammer in his hand, and this artifact should also try its practical value.

Han Du faced the stone wall of the cave, jumped high and knocked the hammer hard against the stone wall, with a soft click, the curved flat front end of the invincible mountaineering hammer hit the stone wall, followed by the automatic deep length, and the hammer was firmly stuck in the stone wall.

Han Du clung to the invincible climbing hammer, and the person was suspended in the air, ten centimeters above the ground.

Han Du's other free hand was raised high, grasping the protruding part of the stone wall, and then took out the invincible climbing hammer, and continued to nail the hammer to a higher position.

The hammer was in tune with him, and whenever he wanted to pull the hammer out of the stone wall, the tip of the hammer would automatically shorten.

In this way, Han Du quickly climbed to the middle of the stone wall, continued to swing the invincible climbing hammer, and soon reached the small passage above the stone wall.

The whole process took less than two minutes.

With a thought, the invincible trekking hammer was withdrawn into the system data sheet, and the person crawled towards the leopard in the small passage.

In the distance, he saw the isolated leopard, and even a red spider had crawled to the place where it was standing, only to be kicked out by it.

Other spiders continue to approach the area.

"Leopard, look at me here."

Han Du began to call in a low voice, and the leopard below, who was a little depressed, raised his head and looked at it, and immediately cheered up, and his mouth was full of water.

Now the vertical distance between the leopard and Han Du is about five meters, but the higher the stone wall goes, the steeper it becomes, and the leopard can no longer jump to the top and stand.

Han Du directly stretched out a hand to pull the leopard up by himself. The leopard also realized it very cleverly, and jumped up at the right time, and the two red spiders under its feet just crawled to the position where it had just stood, and tried to attack it with its teeth and claws, but it was too late.

Han Du now had amazing strength, and he grasped one of the leopard's front legs with agility, and effortlessly pulled the leopard to the edge of the small passage, and then it was able to climb into the small passage by itself.

Below, countless red spiders saw their prey that had consumed a lot of their time and energy run, and they went completely crazy, intensively using their tentacles to transmit information to each other, as if they were discussing countermeasures.

Many, more red spiders crawled out of the crack, and among them was a huge red spider that was five times larger than the others, the size of an egg.

Han Du observed these densely moving spiders, and was very surprised to see the egg-sized red spider, and immediately took out his mobile phone to take a picture, and with a few clicks, several clear photos of the big red spider were stored in his album.

In his opinion, this big spider must have lived for a long time, it should be the king of this group of spiders, and it should also be the queen, because the male spider can't live it for so long.

According to the nature of spiders, male spiders are eaten by female spiders after mating with female spiders.

As if it had found that Han Du was taking pictures, the big red spider actually glanced at Han Du above, and then it began to use its tentacles to make contact with other small spiders, as if it was giving some kind of command.

Sure enough, all the spiders on the stone wall came down, and the spiders on the ground also began to move, crawling intensively in the direction where Han Du and the others were going, probably thinking that Han Du and they would come down from it one day.

Han Du didn't pay attention to it, this small passage was a kilometer long, to see how long they could follow.

He climbed in front, the leopard was short, and he followed closely all the way, and the army of red spiders below also followed all the way.

At this time, Han Du suddenly found that the big red spider was also following all the way, and it didn't move on its own, it was carried by a group of small spiders, and the posture was like that of an official master.

Han Du had an idea, he still had a military bow and crossbow on his body, since the other party dared to appear in front of him, why not directly have a beheading battle, destroy their heads, and see if they still followed.

Han Du sat down in the small passage and held the bow and crossbow on his body in his hand, which already contained a loaded crossbow arrow.

The spiders following closely below noticed that the target had stopped, and they had stopped, and the big red spider was also watching the movement above.

Spiders like it that live in underground caves don't know the power of crossbow arrows, and they don't know bows and crossbows at all.

"Whoosh!"

Han Du aimed down, decisively pulled the trigger, and a crossbow arrow shot down quickly, followed by a muffled bang, and the crossbow arrow hit the back of the big red spider, and it was nailed to the ground.

The big red spider was directly penetrated through the body, and the small spider next to it immediately became confused, pounced on the big red spider to watch the situation, and continued to contact each other with its antennae.

After a while, all the spiders were scattered, and they turned around and returned, and without a commander, they were a plate of scattered sand.

Han Du waited in the distance, and saw that all the little spiders were far away, and jumped directly from above, this position was about ten meters high, Han Du jumped down easily, and the leopard ran down the steep stone wall, and finally landed safely.

Han Du pulled the crossbow arrow from the ground, and the big red spider was still stuck in it. He came down not only to retrieve the crossbow arrows, but also to bring back this big red spider, a new species of spider like this, and the leader of the new species, Han Du felt that it was necessary to study it carefully, and just go back and hand it over to the official personnel for them to deal with.

At this moment, Sun Zichao, who was waiting for Han Du to come back, had already stood up from the ground, and now he had recovered a lot of physical strength and was able to move around freely.

"Lao Huang, Brother Han has been out for a while, nothing will happen, right?"

Listening to Sun Zichao's somewhat worried words, Lao Huang also looked back in the direction of Han Du, and at the end of the passage, no figure appeared.

"I don't know, why don't we go along and have a look?"

"Well, that's what I mean, if he is bitten by those little spiders who kill a thousand knives, we can just go and rescue him." Sun Zichao said this, but what he thought in his heart was that Han Du would become as black as before, and then he could make fun of Han Du in turn.
