The Poplar Iron Ox climbed ashore and looked into the doorway.

It looks like a narrow passageway, and the walls on both sides of the passage are also made of black stone, with a slight upward slope at the bottom of the passage, and its surface is also paved with black stone.

The length of the passage is about 123 meters, and it still looks like a passage at the end, except that the 123 meters in front of the head are straight, and after 123 meters, it seems to turn to the left.

"I think it's all made of stone, so there shouldn't be any mechanisms, right?" said Iron Bull.

"I don't think so!" Poplar shook his head, "For the sake of safety, I'd better go in first, you wait outside, and then you can go in when I'm sure there's no mechanism!"

"You won't let me go in first, and you won't let me follow you closely, if there is really a mechanism inside, I can only watch you in distress from outside, so can I rest assured?" said Tie Niu, very unhappy.

"But you have to understand that this passage is so narrow, if a hidden weapon had been shot at me, I could have avoided it, but as soon as I dodged it, you were standing behind me, then wouldn't I have to let the hidden weapon shoot at me to protect you?" Bai Yang patiently explained.

Tie Niu thought carefully that what he said was not unreasonable, but he was still unconvinced, and said: "Anyway, you are always reasonable! But although my martial arts skills are not as good as yours, my reaction speed may not be worse than yours! If you really want to encounter a hidden weapon, you can dodge, and I should be able to, so ...... Let me go in today in the first place!"

As he spoke, he was about to go inside, but he was grabbed by Poplar in time.

"If I say I'm advanced, I'm advanced!" Bai Yang said, already a little unpolite, "Your reaction speed is indeed no worse than mine, but you are far less cautious than me, you can't be convinced by this! Not to mention our two brothers, what are you doing so clearly!"

"Just because they're two brothers, I don't want you to always be in front of me to block danger!" Tie Niu replied sullenly.

Bai Yang really didn't want to continue arguing with him, so he simply came directly to him and said: "It's decided, I'll go in first, you wait outside, I'll let you in and you will go in again!"

He pushed the iron ox to the side and strode into the doorway.

Tie Niu was used to being bullied by him, so he could only say in the back: "Then you be careful!"

Bai Yang responded casually, cautiously walked forward five or six meters away, and suddenly felt as if he had stepped on something under his feet, and his heart was taken aback, and suddenly a shadow flew down from mid-air and crashed directly into his chest.

At the same time, Tie Niu shouted from behind: "Be careful!"

Poplar had a javelin in his hand, and immediately the tip of the spear stabbed out, right on the tip of the shadow that had slammed into him.

I felt a strong force pass from the javelin, knocking Poplar's body backwards and falling out.

As the poplar "fluttered" to the ground, the shadow also "snapped" and fell to the ground, which was actually a thick log column with a sharpened head.

The Iron Bull rushed into the passage, hurriedly reached out to help Poplar up, and asked, "How are you?"

"I'm fine!" Poplar shook his head, but he couldn't help but secretly say that he was lucky.

If his shot had not been stabbed on the tip of the post, but on the side of the point, the tip of the spear would have slid along the slope of the tip, and the pillar would inevitably have hit his body.

Of course, it wasn't a coincidence, and he had already seen the pointed head when the post slammed into his chest.

At that time, he didn't have time to think about it, and immediately stabbed the javelin in his hand towards the pointed end.

His ability can be said to be a rare opponent today, but there is still a bit of luck in stabbing the tip of the wood with the tip of the gun.

Fortunately, he was strong enough to block the inertia of the wooden pillar rushing forward, otherwise his body would fall, and the wooden pillar would continue to move forward, which would inevitably fall on his body.

However, when this wooden pillar was smashed, Bai Yang could be sure that at least in this twelve or thirteen-meter straight passage, there would be no other hidden weapons.

So he didn't let the iron bull go back any further, and the brothers carefully stepped over the wooden pillar, and soon walked through the twelve or thirteen meters straight passage, and sure enough, there was still a passage ahead, but they turned to the left.

And after the turn, the passage is no longer straight forward, but takes on an arc shape. And with a shape like this, at least it can be judged that there will be no hidden weapon that will shoot directly.

However, Poplar still didn't dare to take it lightly, so he could only let the Iron Bull stay a little farther away from him.

The walls on both sides of the passage are still made of black stone, with no reliefs or decorative frescoes.

But just as he was not far ahead, Poplar suddenly noticed that there were two corresponding slender slits on the left and right walls near the foot.

Poplar crouched down, looked closely at the slit, and immediately realized that there must be a mechanism in the slit.

If a person moves forward, the mechanism suddenly stretches out, and maybe the person's feet can be chopped off.

Poplar couldn't help but frown, looking carefully at the ground.

But the ground was completely paved with black stone, and there was no way to find the trap valve in it.

Tie Niu was originally following Poplar from a distance, but when he saw Poplar squatting down to check the corners of the walls on both sides, he couldn't help but walk closer and asked, "What's wrong Lao Bai?"

"There are mechanisms in these two walls, and they are similar to the one that killed Master Ouyang in Wang Jiutang's tomb before!" Bai Yang replied, "It's just that Wang Jiutang is more cleverly designed, and it can't be seen from the wall at all, but on these two walls, there are such obvious slits!"

Tie Niu was startled when he heard this, and he also took a closer look at the two slits at the foot of the left and right walls, and said, "It's not very obvious, if I walk in front, I definitely won't find it!"

He told the truth, but he attracted a glance from Poplar.

"You're still fighting with me to get ahead?"

Tie Niu had nothing to say, so he could only scratch his scalp and ask, "Then what should we do now?"

"I don't know what this mechanism will look like, if a sharp blade suddenly pierces out of the slits on both sides, we won't even have a chance to dodge!" replied Poplar, his brow furrowed from his brow.

Tie Niu suddenly raised his eyebrows and said, "Why don't I carry the wooden pillar outside, and let's use this wooden pillar to explore the way first?"

Poplar was overjoyed when he heard this, but quickly shook his head again and said, "The length of the wooden pillar is at least three meters long, and it can't be carried from the place where it turns!"

Tie Niu thought about it carefully, and said: "It's not that there is no way! Let's first use the javelin head to pierce a few small holes in the wooden pillar, and we don't need to pierce too deeply, just have a mark, and then with our strength, we can completely cut the wooden pillar in two!"

Poplar thought about it for a while, and felt that his idea could be tried, and it was much better than being at a loss now. couldn't help but smile and praised: "You are usually a sloppy egg, but once you become smart, you are really invincible!"

When Tie Niu heard his praise, he couldn't help but be full of joy, and said, "Then let's hurry up and take care of that wooden pillar!"

Poplar nodded, and the two of them quickly turned and exited, quickly returning to the straight passage before.

The wooden pillar was naturally lying on the ground of the passage, and the two of them first used the javelin head to make a few small holes horizontally in the middle of the wooden pillar as Tie Niu said before.

The javelin tip was not very sharp, but with the strength of the two of them, it was easy to pierce a row of small holes.

After that, the two of them lifted the end of the wooden pillar to make the small hole face down against the wall at the bend, and then they raised their feet at the same time, and with all their strength, they stepped heavily towards the middle of the wooden pillar.

Listening to the "click", although the wooden pillar was not immediately folded into two sections, it was also bent down a lot.

Two people change their feet and step on one foot.

There was another "click", one section of the wooden pillar fell to the ground, and the other fell down, leaving only a layer of epidermal fibers in the middle that was not broken.

The wooden pillar weighed only more than two hundred pounds, and the brothers easily carried a section of it and re-entered the arc-shaped passage.

Although the passage is in the shape of an arc, the arc of the arc is very large, not to mention the wooden pillar folded into two sections, even if the entire section of wooden pillar more than three meters long before is carried in, you can also walk around in this arc passage.

It was still Poplar who walked in front until he reached the place where there was a crack at the foot of the wall, and Poplar took a breath and threw the wooden pillar on his shoulder forward.

The diameter of the wooden pillar was more than a foot, and the two slits were only a dozen centimeters high from the ground, so that people could not easily find them.

Therefore, as soon as the wooden pillar was thrown, I heard a few "clicks" in a row, and sure enough, at least a dozen sharp blades stretched out from the slits on both sides, all of which pierced into the wooden pillar.

But the wood was hard, and when the blades were pierced into the pillars, they could not be retracted into the cracks.

Poplar looked closely, and each of those sharp blades was two or three inches wide, and if someone walked into this passage, these sharp blades would suddenly stab out, and they would easily cut off a person's ankle.

Tie Niu couldn't help but smack his tongue again and again, and said, "It's fortunate that you found these two cracks, otherwise we would have become legless monsters!"

In such a tense moment, he actually said a witty word, but unfortunately he couldn't even laugh himself.

He also carried the other half of the wooden pillar on his shoulder, and Poplar told him to wait behind first, and he carefully jumped on the wooden pillar.

The wooden pillar was jammed by the sharp blades on both sides, and the person walked up to the side and fell steadily, not rolling.

Walking forward along the wooden pillar to the top of the wooden pillar, Poplar bent down to look carefully, and found that more than a meter ahead, the slits at the foot of the walls on both sides were closed.

But even if it was more than one meter away, not only the slit at the foot of the wall was still there, but at the same time, at a height of more than 40 centimeters, two other slits appeared.

Moreover, the two slits, one on the left and one on the right, have been extending forward, and from his angle, he can't see how long and far these two slits are.

Poplar frowned, thinking about how to dodge the two slits that were forty centimeters high.

It's only forty centimeters high, and it's a little difficult to even crawl forward.

"What's wrong with Lao Bai in front of me, is my half of the wood still useful?" Iron Bull asked loudly from behind.
