They obviously fell into the water, why did they appear here, and there was still water dripping on their clothes.

Chu Yuchen kept holding on, making sure that there was no danger around, he put Song Yunshu on the ground and shouted: "Yun Shu, Yun Shu!" How are you? ”

However, Song Yunshu just opened his eyes, rolled his eyelids, and then fainted directly.

This is an underwater cave, and the structure here does not look like a natural cave, but like a man-made man-made cave, but some places look like natural, which is very awkward.

At this time, Song Yunshu fainted, and he had no choice but to hold Song Yunshu and place it in a flat position first, so that she would not be relieved to lie uncomfortable.

After gently placing her, he wanted to check the cave, but he took his hand out of Song Yunshu's waist.

He looked up at the structure and topography above, and then wanted to get up and take a look at the intricate cavern.

After Chu Yuchen stood up, his hearing became clearer, and he vaguely heard the sound of gurgling water.

"What the hell is this place? How did we get rushed here? He only felt that he couldn't see, and it was only a matter of a moment that he lost his senses, and it was probably more than enough in the current situation.

Chu Yuchen walked over following the sound of the water, he was not worried about Song Yunshu, he had always been moving within the range of his own vision.

Fortunately, he only found the sound of running water around the corner, and he looked at the scene in front of him in surprise, there was a large pool here, and the water was still flowing.

These living waters show that this waterhole is connected to the outside world, and Chu Yuchen understood in an instant that they were washed out of this waterhole, and there were still a lot of water stains around, and it was estimated that there was more water in the waterhole when the tide was high just now.

They were washed up in the current to where they woke up, and the water in the waterhole dropped quite a bit before this happened.

"Is this an underwater cave?"

Just when Chu Yuchen was puzzled, Song Yunshu over there began to cough.

"Ahem, ahem! Ahem! ”

After she coughed, she slowly opened her eyes, and Chu Yuchen rushed over when he coughed today.

Song Yunshu had already opened her eyes, she looked at the surrounding scene in confusion, Chu Yuchen squatted down to help her up and patted her on the back.

Then he asked, "How?" Do you feel uncomfortable? ”

Song Yunshu shook his head in confusion, then looked around here, and asked aloud, "What kind of place is this?" It's a bit of history! ”

Chu Yuchen also looked at the surrounding environment with her gaze, and then said: "Well, we are flowing down with the water, don't be afraid, wait a while for you to recover, let's go see if there is any way out." ”

Song Yunshu nodded, then covered his mouth again and coughed: "Ahem, I'm fine, let's go see what kind of cave this is!" ”

She stood up strongly, Chu Yuchen supported her behind her, grabbed her waist, and walked towards the opposite side.

"Slow down, it's okay, take your time!"

Song Yunshu was overly frightened, and now the soles of her feet are weak, and she can't walk at all, and she still relies on Chu Yuchen's support all the way.

"It looks like a passageway! What do you think? And the position where we just fell is the position of the sea! ”

Chu Yuchen nodded, agreeing with Song Yunshu's point of view, he suddenly thought of his discovery just now.

"Yun Shu, I made a discovery just now, because you woke up so surprised, so I forgot to tell you."

Chu Yuchen told Song Yunshu that the pond he found was still here, and sure enough, he agreed.

"There is no doubt that we will be washed into an underwater cave, and then we will see where this cave is connected, and maybe we will find the answer."

Song Yunshu said this, Chu Yuchen didn't understand it at first, but after thinking about the meaning of her words, he also knew what she was talking about.

"Yun Shu, are you saying that the enemy army crossed the border line through this passage?"

"It's not certain yet, Lord Wang, let's continue to take a look!" Song Yunshu didn't dare to give Chu Yuchen an answer for sure, not to mention that they were still in the cave now, and it was not certain whether you were safe or not.

Chu Yuchen nodded, he was too anxious just now, so he first confirmed the current situation, and the two of them walked over cautiously.

"Walk slowly and watch your step."

From time to time, Chu Yuchen had to remind Song Yunshu to be careful not to slip.

Song Yunshu nodded, after a period of relaxation, she has now recovered, and she has the strength to recover and recover, looking at the strange environment around her, she feels very strange in her heart.

"Hey, look, those traces are not the traces left by weapons!"

Chu Yuchen followed her over and carefully inspected those traces, and after the two of them carefully examined, they found that these were all traces left by weapons, and not only here, but everywhere were traces left by weapons.

"Well, yes, these are the traces left by weapons, and they are all over there, and it looks like there are troops walking through here!"

Chu Yuchen spoke out and said slowly, Song Yunshu could also understand these truths, Chu Yuchen broke it, it was just that the two of them thought of one place.

Song Yunshu nodded, stretched out her hand to touch those traces, she looked ahead, her eyes were firm, Chu Yuchen looked at her like this, and followed her to look ahead.

She suddenly spoke, "I guess that's probably why they were able to cross the sea!" ”

Song Yunshu can finally be sure now, and he boldly said it, and soon got Chu Yuchen's support.

"There are many roads in these caves and they died, how do you find the right one that leads to them?"

After asking this sentence, Chu Yuchen also thought in his heart, it is estimated that these weapons, there are many traces on the walls of almost every cave, and it seems that they also got the answer after countless explorations.

"No wonder the enemy has been cowering all along, it turns out that they are waiting for the final blow." Chu Yuchen didn't know when they started discovering this passage, and if they wanted to invade our country, he wouldn't just sit back and wait.

Since he discovered this cave, he would either take it for himself or destroy it, but Chu Yuchen preferred the former.

If the enemy can take advantage of it, why doesn't he follow suit?

"Lord Wang, what are you thinking? So I think this cave is very suspicious, could we have gone wrong, otherwise why has there been no soldiers guarding it, such an important place should not be? ”

The more Song Yunshu walked forward, the more suspicious he felt, although there were more scratches on the weapons on this cave, and there seemed to be traces of trampling, but how could there be no enemy guards?

"Judging from the traces on this, it has been five or six years, to say the least." Chu Yuchen suddenly said this.
