After Ye Wudao took the mountain knife and pried it a few times, he took three steps back, rushed forward quickly, kicked heavily on the wall, and with a loud bang, the wall that had been pried away by him suddenly collapsed with a bang, and the back of the wall was really hollow, and a passage about a meter larger appeared in front of Ye Wudao's eyes.

After Ye Wudao cleaned up the collapsed gravel with a mountain opener, he took a flashlight, lowered his head and bent down to drill in, this passage should have been there, but the entrance was blocked, but due to the long-term lack of ventilation, this passage contains a pungent methane, like the smell of chemical fertilizer, if anyone gets some sparks here, then Ye Wudao will have to become a roast pig.

This passage is not straight, but crooked, some places are even smaller than the normal human body, Ye Wudao is not easy to dig in the passage, he can only use the bone shrinking technique, let himself drill through little by little, but he can pass, but his rattan box is stuck by the owner, unless Ye Wudao tears the rattan box, otherwise it will not be able to pass at all.

But Ye Wudao was not in a hurry, took out a talisman, and recited a spell to the talisman with his mouth: "Heaven and earth are in all directions, heaven and earth are caged, the Nine Heavens Xuannu, the Big Dipper Star Monarch, the Taishang Immortal Master, give me instructions, swoop!"

After reading it, Ye Wudao put the talisman on top of his rattan box, only to see that his rattan box was magically reduced by half, and passed through the narrow place smoothly.

This rattan box is not an ordinary box, but a treasure passed on to him by the old man, otherwise, Ye Wudao would not have taken it wherever he went.

But fortunately, this passage became more and more spacious the further he went, but there was no more situation where he was stuck, and Ye Wudao didn't know how long he had been crawling in this dark passage, which was full of biogas, so smoked that he could barely open his eyes, and felt that the skin on his body that was in contact with the biogas was a little hot.

To be honest, if Ye Wudao hadn't been able to hold his breath for a long time, I'm afraid he would have been smoked to death by the biogas, but fortunately he didn't let Lao Wu and Lao Huang follow, otherwise he would have killed the two of them.

But no matter how powerful Ye Wudao is, it is impossible for him to hold his breath for a long time, some ordinary people who have been trained, such as professional divers and the like, can hold their breath for up to half an hour, but a person like Ye Wudao who practices martial arts, he can use internal breath, relatively speaking, the breath will be held for a longer time, and Ye Wudao himself can hold his breath for about two hours.

After Ye Wudao climbed forward for a while, he found that the passage was no longer forward, left or right, but began to become inclined, and became more and more oblique, suddenly Ye Wudao's body slipped, and he felt as if he was sitting on a slide, and he slid down.

After about two or three minutes of sliding, Ye Wudao suddenly crashed out of the passage, plopped, and fell into a pool of water about six meters high at the bottom, causing a splash to the sky.

A gurgling bubble sound came out from under the bottom of the pool, and not long after, he saw Ye Wudao's head coming out from under the water, looking a little embarrassed, and he was still holding his rattan box tightly in his hand.

Ye Wudao hurriedly swam ashore, and couldn't help but sneeze several times in a row, feeling that the water in this pool was as cold and piercing as ice water, if he wasn't a martial arts practitioner, if the qi and blood in his body were vigorous, he might not be able to hold it.

At this time, Ye Wudao had time to take a look at the place he was in, there was a big waterhole at the bottom, and he himself slipped down from a hole about six meters high above the waterhole, which means that his way back had been completely blocked, even if he had a way to go up to the six-meter-high hole above, but this passage was inclined down, and he couldn't climb back.

Ye Wudao took a strong flashlight and checked around, but found nothing dangerous, so he took off the wet clothes on his body and wrung them out before putting them back on, and then began to look for an exit.

I don't know where this hellish place is, the terrain is very complicated, like an ant's nest, there are large and small passages everywhere, it seems that you can get out, but most of these passages are dead ends, even if some are not dead ends, I don't know where they will take people.

Ye Wudao didn't dare to walk around casually, this place was easy to enter and difficult to get out, if he accidentally stumbled and fell to death, then there would be no place for his old face, it is estimated that the old man will be so angry that he will whip him to the corpse.

Ye Wudao opened his rattan box, and he didn't know what kind of magical treasure his rattan box was, obviously the outside was woven with rattan, but when he fell into the water just now, there was not even a little water in the box.

Ye Wudao took out a piece of yellow rune paper from the rattan box, folded a thousand paper cranes on the ground, then bit his middle finger, squeezed a drop of blood on the head of the thousand paper cranes, held the thousand paper cranes in his hands, and recited words to the thousand paper cranes with his mouth.

A starlight fell on the body of the thousand paper cranes, only to see that the thousand paper cranes actually flew up from the palm of Ye Wudao's hand, flew around his head, and then flew into one of the passages according to Ye Wudao's meaning, helping Ye Wudao to explore the exit.

Although this will consume his Dao skills, it is better than exploring it yourself, there are too many passages here, and I don't know what dangers will exist, so I think it is better to be careful and safe.

While the thousand paper cranes were helping him explore the way, Ye Wudao took out some dry food to replenish his strength, which was some bacon and glutinous rice left by Lao Huang for him, although it was cold, Ye Wudao still ate it very deliciously.

After he finished eating, the Thousand Paper Crane also flew back, coiled around Ye Wudao's head three times, and then flew to one of the passages again, Ye Wudao hurriedly followed behind the Thousand Paper Crane.

The thousand paper cranes were like a labyrinth in this passage, interspersing Ye Wudao left and right in these passages, making Ye Wudao also dizzy, and snuggling up to the wall of the passage to catch his breath slightly.

And at this moment, a colorful snake came out of nowhere, it quietly crawled to the back of Ye Wudao's neck, lifted its inverted triangular head, opened its mouth, spit out its forked tongue, revealing the two sharp fangs inside, and then aimed at Ye Wudao's neck.
