Poplar didn't share his thoughts with anyone else, and the others didn't discuss where the dead octopus had gone.

After all, even the existence of this small island is an extremely strange thing in itself, and everything else seems insignificant compared to it.

And the main purpose of today is not only to explore the submarine tomb below, but also to find out the whereabouts of Haizhu.

People who care about Haizhu, including Poplar Tieniu, faintly hope that Haizhu is still alive.

And if she is still alive, she can only be taken captive to the tomb by the shadow that resembles a sea ghost.

Because there will be air in the tomb, and only in the tomb can Haizhu survive until now.

This is also the reason why he knew that the bottom of this deep pool was weird and terrifying, and it didn't seem to exist in reality at all, but Poplar Tieniu had no hesitation to go down to the pool to visit the tomb.

Ding Sicheng also tied a rope around his waist and prepared to go into the water with the poplar iron bull. However, he would not follow the poplar iron ox into the tomb, nor did he say that if the poplar iron cow did not come out for a long time, he would follow him into the tomb to find it.

After all, with the ability of the poplar iron bull, if he goes in, he can't get out, and if he goes in with him, it's just a funeral.

So he said to Poplar Iron Bull like this: "You must be very careful when you go in, if you really can't find the way out, you have to blast in the tomb, and you must choose the right direction." In case the tomb can't be blasted, I'll put the explosives bag into the passage you entered in ten hours and blast it from the outside. So you have to remember that it's eight o'clock in the morning, and ten hours later, that is, in the evening, whether you enter the core of the tomb or not, you must stay away from the passage. ”

"Wouldn't ten hours be a bit short?" Tie Niu couldn't help but answer, "In case the mechanism in the Great Tomb is too difficult to dismantle, and it took us too long to enter the core of the Great Tomb, and we haven't had time to find out if there is a way out, wouldn't it be bad if you blasted from the outside first?"

"This is a submarine tomb, not a land tomb, we don't know how much air can exist in the tomb now, in case the air inside is not enough for you to support until tomorrow morning, even if I blow up the tomb, you will not be able to escape! I even think that ten hours is too long, but unfortunately we can't communicate with each other, so we can only die in ten hours!" Ding Sicheng said.

"Then set it at ten hours!" Poplar said, "After Tie Niu and I go in, we will first find a way out, and ten hours should be enough!"

Ding Sicheng nodded, took off a watch from his wrist, and said: "My watch is waterproof and pressure-proof, it should still be usable at the bottom of the sea at a depth of fifty meters, you wear it on your hand, remember to watch it for ten hours!"

Poplar hurriedly agreed, and Zheng Zheng stretched out his hand to take it. He also has his own watch, and it can also be waterproof, but he doesn't know if it's not pressure-proof, in short, he didn't dare to take the watch with him before entering the sea.

After that, Poplar put his watch on his wrist and put on his diving suit, and then he and Iron Bull brought several bundles of waterproof explosives. In addition, I also brought a set of diving suits down, hoping to find Haizhu in the tomb, and then I can put this set of diving suits on Haizhu.

After that, the Poplar Iron Ox dives into the water first. Ding Sicheng also followed.

Leaving Boss Jin and the surnamed Li in the dinghy, carefully retracting the ropes.

Soon reached a depth of more than thirty meters, the oval pool wall around his body disappeared, and there was no shadow of the island above his head.

However, the poplar iron bull was used to seeing it, and dived directly to the bottom of the sea at a depth of more than fifty meters.

There was still a dead silence at the bottom of the sea, no light, no seagrass, and no marine life.

The mound-shaped man-made building, standing on the empty seabed, looks abrupt, majestic, and lonely.

After all, the Poplar Iron Bull had been here once, so he quickly found the deep hole that had been dug by hand.

Because no one can say what will happen after entering the tomb, so the three of them have a feeling similar to saying goodbye in their hearts.

But he couldn't communicate with words underwater, so Ding Sicheng could only gesture with his hands over and over again, saying that he was waiting under the water, so that the poplar iron bull must be more careful.

Poplar Tie Niu also nodded solemnly to Ding Sicheng, and then Poplar hugged Ding Sicheng first, and then drilled into the deep hole.

The Iron Bull did not follow closely, but first tugged at the rope of the aspen outside.

As a result, just like the submarine tomb found by the Qianlong salvage ship, after the poplar climbed into it to a depth of about twenty meters, Tie Niu suddenly felt a tightness in his hands.

Tie Niu hurriedly wrapped the rope around his arm twice, and at the same time, Ding Sicheng also came up to help pull the rope.

Last time, it was Poplar who pulled the rope of the Iron Bull, but this time it was changed to the Iron Bull who pulled the rope of the Poplar.

But the result was the same, when the iron bull had enough strength to compete with the huge pulling force inside, he suddenly felt that his hand was loose, and the iron bull couldn't retract his strength, and suddenly involuntarily floated upward along the sea.

Ding Sicheng hurriedly stretched out his hand and pulled Tie Niu, and Tie Niu stabilized his figure.

Hurriedly took the rope back to look, but saw that the rope had been torn off, but the hair was broken, and it should have been worn on the cave wall.

This situation is exactly the same as the last time, which proves that the structure of the big tomb in front of you may really be exactly the same as the tomb found by the Qianlong salvage ship.

Tie Niu thought that Ding Sicheng was far less powerful than him, and he could pull the rope alive, but Ding Sicheng was afraid that he wouldn't be able to.

At that time, he was carrying a rope dozens of meters long, and if the rope got entangled somewhere, it would be very bad.

So Tie Niu simply untied the rope in his waist and handed it to Ding Sicheng, Ding Sicheng understood his concerns, and made a gesture again to tell Tie Niu to be careful.

Tie Niu nodded, and also hugged Ding Sicheng, and then bent down and got into the hole.

The cave was formed by slowly dismantling the stones inside, so the walls of the cave are jagged and uneven.

However, the cave is soaked in seawater, and people are basically floating when they go inside, so it is not difficult to walk.

Tie Niu had an extra heart, and instead of going headless and brainless to drill into the hole, the more he climbed forward, the more cautious and careful he became.

But even so, he still couldn't see anything unusual, except that he felt as if there was a large space in front of him, and suddenly, he felt an irresistible attraction that sucked his body forward.

Even though he had already had the same experience before, he still didn't have time to react before he was sucked into a powerful circulation by the attraction, and with that circulation spun rapidly around a large circle.

Turned straight into the dark, not knowing life or death.

Ding Sicheng stood outside the deep cave, and the legs and feet of the iron bull could be seen first, but soon, only the light of the lamp on the head of the iron bull was still faintly visible.

It didn't take long for even the light of the lamp to be seen, and in the vast sea water, only Ding Sicheng was left.

There is no other sign of life on the bottom of the sea, not even a small shrimp or a small aquatic weed, and the complete sense of death and silence will really make people nervous numb and stiff.

So much so that Ding Sicheng, who has experienced countless winds and waves and seen too many strange and dangerous things, also feels hairy at this moment. Even deep down in his heart, there was an urge to flee quickly.

However, he forced himself to stay at the bottom of the sea, and looked around.

But there was nothing around, nothing but seawater.

There is not even a single ravine or a pile of mud in this sea, except for this abrupt submarine tomb, the entire seabed seems to be flat.

Of course, it can only be like, because that's just how he feels. In fact, the distance that could be seen by the eyes alone was so limited that he could neither nor dare to leave the tomb and swim farther to investigate.

He still had a rope tied to him, and he needed to find his way up.

Once he swims too far beyond the length of the rope - of course, the Jin boss and the person surnamed Li will help him pull the rope, but if something suddenly happens, the rope breaks, or the rope falls off the hands of the person above, will he not be able to find the deep pool into the water and will not be able to return to the normal world?

I'm afraid it's very likely!

As Poplar has said before, the sea below does not look like the real world at all, but like an illusory sea of death.

Bai Yang is right, Ding Sicheng also has the same feeling at this moment.

Especially when he is alone at the moment, this feeling is even clearer and stronger.

However, Ding Sicheng still reluctantly suppressed the fear surging in his heart, and insisted on guarding the entrance of the tomb for more than half an hour, making sure that the poplar iron bull must have entered the tomb, so he kicked his feet and floated upward.

More than 20 meters ahead, Ding Sicheng was really nervous, for fear that he would not be able to go back to the deep pool.

Fortunately, after another twenty meters of upward climbing, inexplicably, the oval-shaped stone wall came into view, which was tantamount to telling him that he had returned to the real world safely.

Ding Sicheng couldn't help but breathe a sigh of relief, continued to float up for a few minutes, and then got out of the water from underwater.

Boss Jin and the man surnamed Li were guarding the boat, and suddenly saw Ding Sicheng out of the water, the two of them were also relieved, and Boss Jin opened his mouth and asked, "What about Brother Bai and Brother Tie?

Ding Sicheng nodded. Nothing thrilling had happened under the water just now, but he had a feeling of escaping death, which caused him to be sore and weak now.

Boss Jin has also gone down to this deep pool, so Boss Jin can understand Ding Sicheng's feelings.

So Boss Jin hurriedly pulled Ding Sicheng onto the dinghy, no longer asked, but helped Ding Sicheng rub the muscles on his body.

After more than twenty minutes of silence, Ding Sicheng breathed a sigh of relief, sat up from the dinghy, smiled and said, "The two of them have been in for more than an hour, right?

"I just hope they can find my niece!" the surnamed Li replied with a sad face.

Ding Sicheng had nothing to say, so he could only reach out and pat the shoulder surnamed Li.

After that, all three men stopped talking, and just sat quietly in the dinghy. In order to save electricity, the three of them took turns turning on the lights on their heads.

But in this weird and cold island grotto, sitting quietly like this will make people hairy, Boss Jin couldn't help but break the silence and said: "Master Chen, you said that Brother Bai and Brother Tie can go smoothly......"

He could not finish his words, because suddenly a white light so bright that it was impossible to open his eyes reflected from the bottom of the pool.

All three of them closed their eyes instinctively.

Ding Sicheng hung the poplar and the iron bull, and soon opened his eyes again.

But the white light was too strong, and although it was only a flash, it still made his eyes dazzle and he couldn't see for a long time.

So Ding Sicheng had to close his eyes again, and then opened them, and suddenly, he stood up from the boat.

He was originally calm and calm, and it could be said that Mount Tai collapsed in front of him and his color remained unchanged, but at this moment, he couldn't control his voice and exclaimed: "What's the matter? What about the island?
