It took the brothers more than twenty minutes to find any mechanism on the first wall.

I went to the second wall to check, but I still didn't find anything.

Turning to the third wall, twenty minutes later, Poplar felt a bulge in the corner of the wall that was different from the others.

Poplar first asked Tie Niu to stand farther away to avoid any hidden weapons or the like when the mechanism was activated, and then he pressed the bulge hard.

But nothing happened. There were no openings in the doorway, and no hidden weapons were shot.

However, Poplar believes that this inconspicuous little bulge must be the location of the mechanism. So instead of giving up right away, he pressed the bulge tightly and tried to turn it from side to side.

I heard a soft "pop", and a small piece of the wall retreated inward, revealing a doorway about sixty or seventy centimeters wide and nearly two meters high.

The doorway was between the poplar and the iron ox, so the iron bull cheered and moved into the doorway.

Poplar hurriedly shouted, "Wait a minute!"

Tie Niu immediately stopped, but said in his mouth: "Let me walk in front this time, I can't always let you protect me!"

Poplar didn't say anything, just gestured to Tie Niu to stay silent.

It wasn't until more than a minute had passed that there was no movement in the doorway, and Bai Yang smiled and said: "It's not that I want to protect you, but your understanding of the mechanism is indeed not as good as mine, and you are not as cautious as me!

As soon as Tie Niu heard this, he scratched his scalp and said, "I also want to read and eat thoroughly, but I doze off when I read the book, and I can't help it!"

"Then don't fight with me!" said Poplar, glancing at the Iron Bull, and then peering into the doorway.

Startled, he clearly saw something lying in the doorway.

The thing was covered in bumps and was extremely rough, gray-green in color, and looked like a large crocodile.

Poplar was so frightened that he immediately shrank his head, causing Tie Niu to look at it, then retract his head, and exclaimed, "Crocodile, a big crocodile?"

"Yes, I look like a crocodile, too!" said Poplar, grasping his javelin in both hands, and glancing back into the doorway.

Indeed, it was a crocodile, and it was a huge crocodile.

It just lay in the doorway, just blocking the doorway.

But its eyes are closed and it seems to be dormant.

- At least in Poplar's opinion, the crocodile is dormant, not a dead crocodile.

Although the aspen stared at the crocodile for a long time and could not see the fluctuations in the crocodile's breathing, it was normal for reptiles to slow down and weaken their breathing and heartbeat when they entered a long period of hibernation.

"Such a big crocodile, you say...... Could it be that the grave hole we got into was opened by this crocodile?" said Iron Bull.

"Unlikely!" Poplar immediately shook his head, "First of all, crocodiles live in swamps and rivers, although there are also on the seaside, but at most they live in shallow areas, and I haven't heard of crocodiles in the deep sea;

"That's right!" Iron Bull smiled, "Then where did this crocodile come from?

"It's not impossible!" Poplar replied, "Although this tomb has been built for nearly a thousand years, we have not encountered the problem of the beast dormant through the evil law before, and it was not until we entered the tomb that the beast suddenly woke up and attacked us!"

Tie Niu was right to think about it, and then asked, "Then what should we do now?" This big crocodile seems to be sleeping very deeply, should we just jump over it?"

"This crocodile is so big, its body length is at least two and a half meters, not to mention that it is difficult for us to jump over, and even if we can, we can't jump!" replied Poplar.

"Why can't you jump?" Iron Bull asked.

"First of all, the crocodile's attack speed is very fast, you should know this better than me, if we jump in the air when the crocodile suddenly wakes up, then we will become its mouth;

Tie Niu thought for a moment, then nodded again and again.

"That's right!" If the crocodile takes advantage of this time to attack, the person who falls down won't even know how to die!"

"That's all I can do!" Poplar nodded.

He gripped his javelin, one left and one right, and looked again at the big crocodile in the doorway.

But for fear of the crocodile suddenly jumping out, neither of them dared to stand directly at the entrance of the door, but leaned against both sides of the doorway, and only stretched their javelins into the doorway.

When Poplar took a breath and was about to shout "do it", it was very abrupt, and the crocodile's two small eyes suddenly opened.

Poplar was startled and blurted out, "Do it!"

The Iron Bull had already used all his strength and immediately stabbed it with a javelin in his hand.

At the same time, Poplar also stabs a javelin into the crocodile's head.

The crocodile was already lying at the entrance of the door, so the thorn was on the right track.

One of the poplars was aimed at one of the crocodile's eyes, but the crocodile instinctively tilted its head when the tip of the gun approached. As a result, the tip of the poplar's spear pierced the crocodile's head together with the tip of the iron bull's spear.

The crocodile leather armor was tough, but the strength of the poplar iron bull was far beyond ordinary people, and the two javelins still pierced into the flesh and reached the skull, and the thick crocodile blood immediately oozed from the tip of the spear.

The crocodile had a sharp pain in his head, but he suddenly became fully conscious, and he heard a strange howl, and his whole body jumped forward.

Poplar quickly withdrew his hand after a stab, but Iron Bull withdrew his hand a little slowly, and the head of the spear was still stuck in the crocodile skin.

As a result, the crocodile jumped suddenly, directly through the doorway and fell into the pool with a "plop". The iron bull also stood unsteadily, and fell into the water with his body crooked.

Blood gushed from the top of the crocodile's head, which soon turned the pool red.

But that only provoked the crocodile to be more ferocious, and as soon as the iron bull fell, the crocodile had already turned its head, opened its real bloody mouth, and bit it towards the iron bull.

Crocodiles seem to crawl slowly on land, but in the water, they are as ferocious and agile as sharks.

Fortunately, Tie Niu had seen the power of crocodiles when he was in the army, and he was also attacked by a giant crocodile in the Golden Dragon Tomb under the Crescent Spring a few months ago, so Tie Niu knew very well that once he followed the crocodile into the water, the crocodile would immediately turn its head and attack.

Therefore, at the moment of falling, Tie Niu not only did not panic, but was exceptionally calm and sober.

Seeing that the crocodile's huge mouth was about to bite his body, Iron Bull stretched out one hand and grabbed the crocodile's upper jaw.

Immediately following the struggle on the iron bull's arm, the whole body suddenly flipped upward, and it was able to escape from the crocodile's mouth.

As soon as Poplar saw the Iron Ox fall into the water, he immediately jumped into the water as well.

But he was only afraid of stabbing the crocodile with a javelin, and he couldn't kill the crocodile with one blow, but made the crocodile attack the iron bull more fiercely, so he could only throw the javelin to the shore, stretched out his arms, grabbed the crocodile's tail and threw it back.

The crocodile missed the bite and quickly launched a second attack on the iron bull, but unexpectedly, its tail tightened, and it was unable to jump forward.

The crocodile was three meters long and weighed more than three hundred kilograms, but if it was on land, with the strength of the aspen, it was completely possible to hold its tail and shake its whole body violently.

However, the poplar was powerless in the water, and this flick only stopped the crocodile from pursuing the iron bull, but the crocodile twisted its tail and immediately threw the poplar's body out of the water and hit the shore hard.

At the same time, the crocodile's long head also flicked its tail and slammed into the iron bull.

Iron Bull just left the crocodile's upper jaw with one hand, and saw that the crocodile had hit, so he could only make another dangerous move, so he turned over in the water, and slapped one hand on the crocodile's skull, and his strong body turned up again, climbing directly on the top of the crocodile's head.

The crocodile immediately tilted its head to shake off the iron bull, and the iron bull crossed his legs, clamped the crocodile's head tightly, and at the same time swung his fists and smashed them into the crocodile's eyes.

This smash was right, although the crocodile's skin and flesh were tough, but its eyes were the weakest place after all, and it was hit by the iron bull with all its strength, and suddenly the eyeballs cracked, and the iron bull's fist was dyed sticky.

The crocodile let out another strange howl, and its whole body flipped backwards, directly pressing the iron bull into the water.

But as soon as it was flipped like this, the soft belly was immediately exposed upward.

Poplar was thrown to the shore by the crocodile, and immediately reached out to grab the javelin thrown on the shore, and suddenly saw the iron bull smash the crocodile's eyes, which provoked the crocodile's whole body to turn upside down, and Poplar immediately grabbed the javelin and stabbed it hard at the crocodile belly.

This one pierced directly into a few tens of centimeters, and the crocodile immediately turned its body, and Poplar grabbed the barrel of the gun and dived into the water, grabbing the barrel of the gun with both hands and twisting it fiercely.

The crocodile was so painful that its entire body writhed in the direction of the gun's twist, and blood gushed out, quickly staining the pool red.

At this point, however, the Iron Bull found his javelin from under the water and stabbed the crocodile in the abdomen with a shot.

The crocodile was held up by two javelins, and could not dive to the bottom of the water to bite the Poplar Iron Ox, so it could only struggle to climb ashore.

But its eyes were so sparse that it couldn't find its way at all. Furthermore, the Poplar Iron Bull twisted the barrel of the gun, causing the tip of the spear to stab and scratch inside its body.

Although the crocodile has a big life, it can't help tossing like this. It managed to reach the shore with its two front legs, but it slipped down again, and never moved again.

At this time, the whole pool of water had turned blood red, and the poplar iron ox had just surfaced from under the water.

The two brothers looked at each other, recalling that Tie Niu was moving a little slowly, and at this moment he had been bitten in two by the crocodile's huge mouth, and both of them were a little afraid.
