The passage is irregular, the hole is sometimes large and sometimes small, sometimes bent and sometimes straight, and the height is also extremely unbalanced, which should be naturally formed.

But the length of the passage was much larger than the two expected, and after the two swam hundreds of meters, they didn't even feel the slightest feeling.

"Sanbao, why don't we go back, I feel a little bad?" Lin Hai stopped and turned back to Sanbao and said.

"Maybe it's almost the end, I can vaguely sense something! Isn't it just a third-order spirit python, the two of us work together, are you really afraid that he won't succeed?" The two of them had already wasted a lot of time, and they were really reluctant to let Sanbao give up.

Finally, after a distance of a thousand meters, the hole suddenly became larger, and gradually upturned, and in a short time, the passage had completely dried up, and the two of them crawled out of the water, and suddenly breathed a big sigh.

It's a little better to be down-to-earth.

In any case, it is a little awkward in the water, and on land, even if the anaconda has three heads and six arms, there is nothing to be afraid of.

However, when a huge cave appeared in front of them, they both changed their minds.

The hollow cave is very large, roughly estimated to be at least a kilometer long and wide, and the roof of the cave is covered with various inverted stalactites of different sizes, as if they will fall at any time.

The stalactites emitted a faint white light, shining the originally dark cave under the noses of the two.

"Oh my God, what is this?"

When the two of them saw what was on the ground, they couldn't help but let out a soft shout.

Just now, the two of them also said that there was nothing to be afraid of third-order spirit pythons, that was because they were two to one, but if it was two against hundreds, the two of them would only have to escape.

This is exactly the case, the ground of the entire cave is covered with spirit pythons of various orders of different sizes, the small ones may only be first-order spirit beasts, but most of them are second- and third-order, and the two of them don't even suspect that there is a fourth-order spirit python king lurking somewhere in the cave.

The two roughly estimated that there were at least nearly a hundred second-order spirit pythons in the cave, and the third-order spirit dreams were also above thirty.

Naturally, there are so many spirit pythons, maybe there is a spirit snake Neidan, and there are so many spirit pythons in worry, and the two of them have dealt with it.

"It's weird, how come there are so many second- and third-order spirit beasts on the periphery of this maple needle forest, this is not normal, as far as I know, the entire maple needle forest is dominated by ordinary beasts and first-order spirit beasts?"

"I think it should have something to do with this cave, if my guess is right, there must be some good genius treasure in it!"

Lin Hai's experience is so rich, he immediately saw a hint of it.

The two didn't dare to disturb any of the spirit pythons, and after retreating nearly a hundred meters, they discussed in the passage.

"If you want to deal with so many spirit pythons, it's too difficult, you really can't do it, you have to go to Miao Tian! It's just that the old fox is here, I'm afraid our benefits will be greatly reduced." Sambo sighed.

The more critical the time, the more Sanbao felt that his strength was too low.

"Forget it, it's a little life, let's go and ask Miao Tian to come out!," After some thought, San Bao still decided to give up.

Fortunately, the passage in this waterhole is very hidden, and if they didn't happen to see the giant python devouring the civet cat, the two of them wouldn't have found it at all.

If you can't find the passage, you won't be able to find this big cave.

As soon as the two of them wanted to turn around, a hissing sound suddenly came from inside the passage.

"It's not good, it's been discovered, let's go quickly......" The two fled in embarrassment, but before entering the water, Sambo paused again.

Under its powerful perception, a second-order spirit python swam slowly in the distance.

"No, only a second-order spirit python has come, and the speed is not slow, it should be out to forage, if that's the case, then we?" Suddenly, an idea appeared in Sambo's mind.

These spirit pythons do not blindly stay in the cave, but will come out to forage for food every once in a while, the best thing is that they seem to act separately, which gives the two of them a chance to break through, as long as the two act cautiously, they can slowly eliminate the spirit python in the cave.

The two held their breath and slowly entered the water, and when the spirit python just entered the water, the two started at the same time.

There was hardly any sound, and the five-meter-long second-order spirit python was instantly killed by the two of them, and the water surface was blood-red.

The two of them slowly came out of the water in disheveled clothes, and Lin Hai cleanly dug out the snake gall of the spirit python and put it in his pocket.

The most valuable thing on this second-order spirit python is his snake gall, and the second-order snake gall is one of the alchemy materials of many spirit pills.

"Brother Lin, you wait here, I'll take a look," the two waited for a while, but no more spirit python came, and Sanbao was a little impatient, so he returned to the cave alone.

After a moment, Sanbao poked his head out of the passage again, and all the spirit pythons in the cave were prostrate on the ground, without the slightest intention of getting up.

It's not a way to die like this, you have to think of a way to lead it out one by one, so that it's fast, otherwise, I'm afraid you won't be able to kill these spirit pythons in ten days and half a month.

Pregnant.

San Bao suddenly remembered that the spirit python liked to eat low-level spirit beasts, returned to the entrance to the water, said hello to Lin Hai and immersed himself in the water.

Half an hour later, Sambo dived back again, still carrying a poor little black pig in his hand.

"Hey, you killed another spirit python?" Seeing the corpses of the two spirit pythons, San Bao asked.

"Yes, I just finished killing, and I'm a second-order little guy, I can't give birth to Neidan, no matter how much I have, it's useless! And it's too slow," Lin Hai shook his head as he wiped the blood on the treasure knife.

"Don't worry, just get ready for the event, I'll bring a few over," San Bao waved the first-order little black pig in his hand, which had already opened its skin, and turned to leave.

As soon as they arrived at the entrance of the cave, nearly ten spirit pythons nearby seemed to move, and they were so frightened that Sanbao ran away, obediently, which attracted more than ten at once, and they didn't eat themselves.

Although the three treasures ran fast, but because they were too close, the smell of blood on the little black pig had attracted the attention of many spirit pythons, and although the breath disappeared quickly, there were still nearly five spirit pythons swimming into the cave.

"Brother Lin, I didn't operate it well, I attracted five at once, three of the second order, one of the third order and one of the first order, can you deal with it, if you can't deal with it, go back first, and then come down later. Sanbao hurriedly turned around and told Lin Hai, who was sharpening his sword, about the situation.

"There's only one third-order, that's not a big problem, you're responsible for dealing with a few small ones, and I'll deal with the big ones," the two finished dividing labor, and soon the leading third-order spirit python appeared in front of the two of them.

Fortunately, the wisdom of these spirit pythons is extremely low, and when they saw the three treasures and the corpses beside them, they did not call other accomplices, but instinctively rushed towards the two.

Lin Hai dodged and rushed forward, and with a single slash, he drew a big seal on the belly of the spirit python, and the three treasures took the opportunity to pass over the other spirit pythons that the two of them rushed to.

A phantom, five golden rays of light crossed, and the spirit python led by seven inches was caught in the heart, and immediately walked on the ground softly.

At this time, the other two spirit pythons, one left and one right, attacked at the same time.

With two hisses, two small green swords stabbed towards Sanbao, which was a spiritual attack with venom, Sanbao easily dodged, his body flashed a few times, his hands and feet moved together, and after two sneers, the three second-order spirit pythons were killed one after another.

The battle was over in the blink of an eye, and when the last first-order spirit python swam to him, the Three Treasures were waiting for him.

Not to mention, although the wisdom of this spirit python is low, but the instinct to escape is there, maybe it is to see the three treasures three times five divided by two to get a few second-order spirit pythons, the little python turned around and fled.

"Can you escape?"

Naturally, the Three Treasures would not let him go back, although his wisdom was low, if he could report to other similar people in some way, the two of them would be in danger.

In a few flashes, the three treasures caught up with the little python, the golden light flashed, and the nine folds of claws made another contribution, easily killing the four spirit pythons that came to attack.

Turning around, the third-order spirit python had been beaten all over by Lin Hai, but its head and seven inches of protection were excellent, and it had not been attacked, which was one of the reasons why Lin Hai had not succeeded.

"What else are you looking at, come to help?" Although Lin Hai was relaxed, he couldn't kill his opponent in seconds, so he had to call out Sanbao.

When dealing with these low-level opponents, the Nine Turns of the Three Treasures' golden body could almost exert one hundred percent efficiency, several golden lights flashed, and with Lin Hai's huge red light, the Spirit Weapon Treasure Knife cut the Spirit Python into two sections.

"Sanbao, have you noticed it, the spirit python in this cave seems to be much weaker than other spirit beasts of the same level!"

"When you say that, it's true, those second-order spirit pythons, they feel slightly stronger than this little black pig, no matter what, their weaknesses, we are better......"

After some tidying up, the two went into action again.

After the first experience, Sanbao no longer dared to put the black pig too close, these spirit pythons were extremely sensitive to the smell of blood, and the first time they were lucky, there was only one third-order in it, otherwise, the two of them would not be so easy.

Three days later.

The huge passage was already lined with the corpses of the civet pythons.

"Three treasures, how many spirit pythons are in it, if there are few, we can rush in and kill them directly! Although the realm of these spirit pythons is not low, their combat power is too poor, I really don't know how to cultivate it,"

After killing a third-order spirit python, Lin Hai was already a little impatient.

"There should be less than twenty of them, of which there are four third-order spirit pythons, and the others are all first-order, and some have even just been born! Not even first-order," as the spirit python continued to stop killing, the two of them became more and more confident.

"Okay, let's go, I hope there can be Neidan in these four third-order lines, otherwise, we will be busy in vain these days~" Lin Hai carried the treasure knife on his shoulder and led the way in front.
