Poplar and the other three looked at each other.

After a while, Ding Sicheng said: "Don't be so frightened, we have just carefully searched this big house, and there must be no other living creatures in it......!" Even if something strange had ever come in, it would have already gone out! This should be a good thing for us, because as long as something else has gone out, then we are not afraid that we will not be able to get out!"

Bai Yang and Jiang Peng both felt reasonable, but Tie Niu suddenly said, "Could it be that the sea ghost walked in front of Master Jiang and them and opened the door of this passage?"

"Impossible, right?" Poplar said, "Although this sea ghost is thoughtful and cunning, it should not be cunning enough to find and open the tomb mechanism!

"I remember!"

Jiang Peng suddenly shouted, causing everyone else to focus their eyes on him.

Jiang Peng was stunned and said, "After Xiao He and I broke up with Master Chen, I also encountered a fork in the road, but it was just ...... I discussed it with Xiao He, and we all felt that there were only the two of us left, and we shouldn't go separately anymore, so we instinctively chose one of the passages, and as a result, we walked into this core burial chamber smoothly. Will...... What mystery is hidden in the passage where Xiao He and I didn't go?"

"Very likely!" Ding Sicheng nodded immediately, "Then please ask Master Jiang to lead the way and go to that passage to have a look!"

"Actually, you don't need me to lead the way, it's not a long walk to get there!" Jiang Peng said.

Several people immediately turned around and continued along the passage.

It was still Poplar who walked in front with a javelin in his hand, and sure enough, he didn't go far, and there was a fork in the road in front of him.

"Xiaobai, wait, I'll go ahead!" Ding Sicheng said, and hurriedly walked to Bai Yang's side in two steps.

Bai Yang knew that Ding Sicheng loved himself, but Ding Sicheng was indeed more experienced than him, so he had to hide his gratitude in his heart and honestly follow behind Ding Sicheng.

Fortunately, before they could encounter the mechanism, several people suddenly discovered that in the corner of the wall on the right side of the passage that they had not walked through, there was a rather large hole going down.

The entrance to the cave was covered with rocks and sand, and it was clear that the passage was not left by the tomb builders, but had been pierced by something.

I looked down the entrance of the cave, but there was no bottom below.

And with the diameter of this big hole, it is enough for sea ghosts to drill in and out.

"It seems that this deep hole was really dug by the sea ghost!" Ding Sicheng said, but his brows did not stretch there, "But the sea ghost ...... Do you really know how to open the tomb mechanism?"

"Will it be ......?"

Poplar suddenly spoke, but only said three words, and did not go any further.

The other three all looked at him, and Poplar sorted out his thoughts a little before he continued, "My guess is that it is possible that someone else entered this tomb many years ago. The entrance to the passage we came in was dug through by this man. It's just that what this person didn't expect was that there was another mystery in the tomb, once the sea water entered the tomb, the first protective mechanism of the tomb was immediately activated, causing the sea water to form a powerful circulation, as if creating a protective cover for the tomb! As a result, the first person to come was just like us, and was also washed into the tomb by the circulation. And the man found that he couldn't go out the same way at all, so he had to dig another way out. And the reason why he dug down was precisely to avoid the circulation around the tomb. Outcome...... It is not known whether this man got out alive, but the deep hole he dug was discovered by sea ghosts. It's just that the sea ghost is larger, so it can only drill into this deep hole all the way, and the sea ghost has to expand this deep hole a little bit along the way, which makes it full of sand and gravel, as if it was completely dug out by the sea ghost. ”

Poplar's speculation can be said to be very bold, so bold that Tie Niu and Jiang Peng are a little confused.

Only Ding Sicheng thought about it a little and said, "What you said is not impossible, the question is...... What is this man doing when he comes in? When we came in, the coffin on the wooden boat was nailed well! It is impossible for this person to come in and dig a hole again without taking anything, right?"

"You don't have to take anything, do you? maybe...... What orbs and so on!" said Poplar.

Ding Sicheng immediately understood what Baiyang meant.

He said that the person who came in took the psychic orb, and the reason why the man didn't touch anything else was that the person knew very well the value of the psychic orb, and with the psychic orb, other things were like waste;

Secondly, in the depths of this sea, it was not easy to take away other things intact, and that person just wanted to leave alive with the psychic orb at that time, so he didn't bring anything else as a burden.

Ding Sicheng pondered and didn't say anything, Tie Niu looked at Bai Yang, then at Ding Sicheng, and couldn't help but interject and said: "If Lao Bai said so, someone would have already come into this tomb and taken it...... What a jewel to that, but ...... Since that orb is so precious, even if it is not placed in a coffin, there should be a box dedicated to this orb......, right? Lao Bai, you said, that small jewelry box can't hold that big orb. But we didn't find any other boxes, so the man wouldn't have taken the box with the orb, would he?"

"Maybe the jewel was in the coffin......! After the man took the orb, he nailed the coffin untouched, and after many years, it is difficult for us to find that the coffin has been opened. Poplar explained.

Tie Niu thought for a moment, but still shook his head.

"It's still not right! When we came in, the mechanism along the way was not even cracked! The big crocodile was alive and well, why didn't it attack the first person to come?"

When Tie Niu asked these questions, Bai Yang was already thinking in his heart, so as soon as Tie Niu's voice fell, Bai Yang quickly opened his mouth to answer.

"It's not that it's inexplicable! Maybe the guy who came in was extremely proficient in the Great Tomb Mechanism, and he was very good at it! Or maybe ...... That man was the one who built the tomb in the first place, so he was able to enter the core chamber without damaging any of the mechanisms!

"Lao Bai, what do you mean is that the person who came in knew that there was a ...... in the tomb What kind of orb is that, so the purpose of his entry is for that orb?" Iron Bull asked again.

"I think it's very likely!" replied Poplar, "and as for the fact that he nailed the coffin and did not close the door to the core burial chamber, it is very likely that something unexpected happened at the time, which caused him to forget to close the last door in his hurry to dig the hole." ”

Tie Niu opened his mouth and closed it again, unable to think of other problems for a while, so he could only look at Ding Sicheng in a blink of an eye.

Before Ding Sicheng could express his position, Jiang Peng couldn't help but ask, "What do you say...... What kind of orb......? What other precious orbs are missing from this great tomb? How do you know that such a orb exists?"

"We don't know!" Bai Yang replied immediately, "I just made a hypothesis, so my master and my brother will follow my hypothesis!"

Jiang Peng let out an "oh", looked at Ding Sicheng suspiciously, and then looked at Tie Niu.

Ding Sicheng smiled faintly and said, "I think Xiaobai's speculation is very reasonable......! No matter who dug this deep hole, and no matter if anyone else has entered the tomb before, in short, this passage is likely to be the passage out!"

"Then let's not say more, let's go straight through this hole and try it!" said Iron Bull.

"It's okay to go in and try it, but this passage goes straight down, and even if we can get out, the pressure of the sea will be stronger, so we have to find a few intact air canisters on our backs! My air canister has been smashed by the mechanism in order to avoid the mechanism!" Ding Sicheng said.

"Xiao He's air tank is still intact!" Jiang Peng immediately said, "It's just ...... It's covered in blood, and you'll have to go back and get it!"

Xiao He's air canister was thrown next to the entrails on the floor in the big room over there, and Bai Yang and the others had seen it before.

It's just that just thinking about finding the way out first, no one thought about carrying Xiao He's air canister.

"I can carry that air canister on my back, but what about Tie Niu and Xiaobai?" Ding Sicheng said, looking at Poplar and Tie Niu.

"I don't care! I'll hold on for thirty minutes in one breath, but I'll have to find another air tank for the old black to carry on!" said Poplar.

"You'll only be able to hold on for up to ten minutes longer than I can, so if you're looking for air tanks, you'd better find two. Tie Niu said.

"Don't bother!" Poplar shook his head, "You put the air tank on your back, I just need to follow you closely, and when I can't hold it back, I can just take two sips of your air tank!"

When Tie Niu heard this, he was right, and said, "Then go back the way you came, and find the air canister you threw in the house where there were crocodiles." Anyway, the mechanisms along the way have been cracked by us, and we are not afraid of any more dangers. ”

Bai Yang nodded, but he didn't say anything, just looked at Ding Sicheng and waited for Ding Sicheng to make a decision.

Ding Sicheng thought for a moment and said, "There are also a few air canisters thrown in the burial chamber where there are water zombies over there, and there are piranhas over there, so ...... It's better to go back to the room you came in before and find the air tank!"

"Shall we go separately or together?" asked Poplar again.

"I think it's better not to separate!" Jiang Peng hurriedly replied.

Ding Sicheng knew that he was frightened by the sea ghost, so he nodded and smiled, and said, "Then don't separate! You first go with us to the big house to find Xiao He's air canister and put it here, and then go to the room where he first came in to find Xiao Bai's air canister!"
