Ding Xiaoruo vomited a few saliva. She looked at Lin Nantian and Heizi. She seemed to understand, looked around and said, "What's wrong with me? Where is this place?"

Lin Nantian couldn't help but shake his head and said, "I don't know where this is, but this place should be inside the waterway."

"Inside the waterway?" Ding Xiaoruo looked at it strangely and said, "What kind of waterway is this?"

Lin Nantian shook his head and said, "I really don't know what kind of water channel it is."

At this moment, Kuroko said coldly: "This is the drainage channel of the underground palace."

"The drainage channel of the underground palace?" Lin Nantian was shocked and said, "Have we entered the underground palace?"

Heizi nodded and said, "That's right."

Lin Nantian wondered and said, "But we haven't found the entrance to the underground palace before."

Kuroko didn't answer, so she swam forward.

"Damn, this guy..." Lin Nantian looked at Heizi swimming forward and had to curse secretly.

At this time, Ding Xiaoruo said: "He said yes, this should be the drainage channel of the underground palace."

Lin Nantian said strangely: "Why do you think so too?"

Ding Xiaoruo smiled and said, "Look at the difference between where we are now and before?"

Lin Nantian looked at it and saw that the walls on both sides were made of green stone bricks. He looked up and saw that there were also green stone bricks on the top.

Looking at the wall, the stone bricks were neatly built without any confusion. The place was not very big, and there was no way to go under the water.

What is the drainage channel in the underground palace?

"This is really the drainage channel of the underground palace." Lin Nantian looked and nodded.

Ding Xiaoruo swam in front, looking at the stone bricks on both sides while swimming.

Suddenly, she said, "What is this?"

Lin Nantian swam over and saw a square hole about one meter wide on the wall.

The opening was opened from the wall. When the flashlight shone, you can see that it was already full of water. You can see that it was very deep inside along the flashlight.

It can be seen that this is another drainage channel.

Ding Xiaoruo said: "This opening should be a drainage channel."

Lin Nantian looked at it, nodded and said, "It should be. But where does this drainage lead to?"

Ding Xiaoruo said: "It should be a tomb that leads to a certain underground palace."

Lin Nantian said, "Then we can swim in here and then we can directly enter the underground palace?"

"Although it is certain that the water here passes through somewhere in the underground palace before flowing into this drainage channel, it is not easy for us to be sure if it is." Ding Xiaoruo shook his head and said, "Just say that it is possible that this hole can be directly accessible.

The tomb in the underground palace, but we couldn't swim through it with water."

Lin Nantian said: "But, where did this underground palace water come from?"

Ding Xiaoruo said: "Of course I came in from inside and outside the underground palace."

Lin Nantian thought for a while and said, "Can the underground palace be submerged?"

Ding Xiaoruo shook his head and said, "The underground palace should not be flooded yet."

"What do you mean?" Lin Nantian's eyes lit up as he heard it, as if he had seen hope.

Ding Xiaoruo said: "The bottom drainage in the underground palace is very good. The drainage channels on our side have not been submerged, so the underground palace must have not been submerged."

Lin Nantian listened and looked forward.

Suddenly, Lin Nantian was stunned. Because at this moment, the blackspot swimming in front of him had disappeared.

"Xiao Ruo." Lin Nantian shouted in a low voice, then said, "Where are others?"

When Ding Xiaoruo heard this, he turned his head and looked at the water surface in front. He was puzzled. He saw that the water channel was a bit long and went straight forward, but there was no sign of Heizi.

So, Xiao Ruo said in wonder, "Why is he missing?"

Lin Nantian couldn't help but feel a little shocked in his heart and said, "Can he be swimming under the water?"

"No way?" Xiaoruo said in surprise, "What is he swimming under the water?"

"I'll go and have a look." As he said that, Lin Nantian sank into the water and looked forward. He saw that the water was quiet and there was no sign of a black man at all.

Lin Nantian surfaced, and couldn't help but reach out to wipe the water from his face, saying, "It's strange, this guy isn't in the water either."

Ding Xiaoruo thought for a moment, and she shouted, "Let's swim forward and take a look."

Lin Nantian nodded and swam forward with her.

After swimming for a few distances, Lin Nantian suddenly felt a stream of water flowing into the wall on the left.

"Huh?" Lin Nantian couldn't help but shouted strangely: "There seems to be water flowing on the wall here."

Ding Xiaoruo had already known it, Lin Nantian said, and had already seen her looking at the wall.

Lin Nantian swam over and saw no cracks on the wall. What's strange is how the water flow came out of the wall?

Lin Nantian looked at it and became strange.

Still at this moment, Ding Xiaoruo suddenly dived into the water.

With the flashlight, Lin Nantian could see Ding Xiaoruo sinking directly into the bottom of the water.

The bottom of this drainage channel is also very deep, and Lin Nantian estimated that it was about three meters deep.

After a while, Ding Xiaoruo floated out of the water and took a few breaths of air. She said, "I'm still wondering, it turns out that the water flow didn't flow out of this wall at all."

"Didn't it flow out from here?" Lin Nantian couldn't help but say strangely: "Did it flow out from there?"

Ding Xiaoruo smiled and said, "It flowed from the wall on the right."

Lin Nantian looked at the wall on the right, shook his head and said, "It's not right, there is no water flowing on the right."

Ding Xiaoruo said, "Of course we can't feel it above."

"But, isn't this water flowing here? It's clearly flowing out of the wall on the left." Lin Nantian still believed that his judgment was correct.

Ding Xiaoruo said, "I won't argue with you. You can go down to the bottom of the water and see what's going on."

Uncontrollably, Lin Nantian sank to the bottom of the water.

As soon as he reached the bottom of the water, Lin Nantian discovered that as Ding Xiaoruo said, the water flowed from the wall on the right.

"Can it be that the water flowing from the right wall to the left wall and then reflecting it makes people feel that it is flowing from the left?" Lin Nantian thought for a while and found that this is indeed the case.

So Lin Nantian swam up and was about to speak, but he saw Xiaoruo staring at the wall on the right.

"What's wrong?" Lin Nantian looked at her strangely and asked, "Is there any problem with the wall?"

Ding Xiaoruo said in confusion: "I saw this wall move just now."
