Thinking about it, Xiang Hanyu suddenly remembered a very serious problem, that is, after the stone house was opened by the Quiet Treasure, it should have been an hour or two.

According to the ancient times, an hour is equivalent to two hours, so wouldn't it be that the door of the stone house will close automatically.

Thinking of this, Xiang Hanyu was about to pull Quiet Po out of the stone house, but he found that the door of the stone house began to close slowly after a "click......

Xiang Hanyu hugged Quiet Bao tightly again in a hurry, and threw himself forward.

Just as their heels left the gate of the stone house and fell into the water again, the two heavy stone doors closed tightly.

It's really hanging, if it's a step too late, the calf will be caught by the stone gate, and even if it doesn't die, it will be crippled.

The two of them got up from the water in embarrassment, and looked at the closed door of the stone house with trepidation, and were surprised to find that many fish were caught in the cracks of the door.

Some multicolored fluorescent liquid kept coming out of the cracks in the door.

It seems that this glowing fish does not just glow on the surface of the scales, but also glows all over the body.

Because there were many of these glowing fish in the water below, they could still see their surroundings clearly, even though the stone house was closed and there was no wall lamp illuminated by the night pearl inside.

Quiet Bao looked around, but he didn't feel very scared, firstly, those beautiful and glowing fish brought light and were pleasing to the eye, and secondly, there was Xiang Hanyu by his side, and his heart was much more steady.

Only Xiang Hanyu frowned, staring at the waist-length water and the ancient books that had been wet with water, and fell into deep thought.

How do you get out of here?

Rashly jumped into the passage with the quiet treasure and swam out, I really didn't know the bottom of my heart. But standing here stupidly, waiting for the air to run out, is still a dead end.

"Hey, Hanyu, this book is wet and there are still glowing words." Just when Xiang Hanyu was at a loss, the quiet treasure beside him suddenly pointed to the soaked ancient book in his hand and shouted in surprise.

Hearing Quiet Bao's shout, Xiang Hanyu withdrew his thoughts, glanced at the ancient book in Quiet Bao's hand, his eyes lit up, and he quickly took the ancient book from Quiet Bao's hand, and looked at it page by page.

Looking at it, the expression on Xiang Hanyu's face became more and more weird, and he was even a little afraid.

He never expected that after this ancient book was soaked in water, a large fluorescent ancient text would be displayed in the middle of each page.

In order, it is exactly two sentences:

The real secret of the love of life and death tower mechanism is that you want to marry me today, if you don't see this glowing word into the tower, you will die.

At the moment of reading these words, Xiang Hansheng had to admire the creator of the Fengqi Grottoes, in order to prevent future generations from easily finding the Fengqi Grottoes, he even hid the ancient books that gave people tips.

Obviously, the younger brother of the skeleton man from before should also be dead. Although he left the stone house alive, he thought that after reading the ancient book and studying it carefully for an hour, he had completely mastered the secret of cracking the mechanism.

As everyone knows, the secret is not the words recorded in the book, but only the fluorescent words displayed when the ancient book is soaked is the real secret.

It is estimated that when he confidently walked into the Tower of Life and Death and cracked the mechanism according to the secret written in the original ordinary text of the ancient book, he was instantly killed or trapped by the mechanism.

In order to seek immortality, these two brothers came here through great hardships, and finally died.

When Xiang Hanyu mourned the experience of the two brothers three hundred years ago, the ancient book in his hand was completely cracked due to soaking wet, and fell into pieces and fell into the water.

"Hanyu, it's all because I didn't keep the ancient books, what should I do, why don't you quickly fish them out, and maybe they can still be used after drying them and putting them together?" Seeing that the ancient book was completely rotten after reading it, Jing Bao said very guiltily.

After saying that, he bent down in the water and desperately tried to pick up the fragments of the book, but found that it was too late, and the fragments in the water melted as soon as they touched it, and the ancient book had been completely scrapped.

"It's okay, now the ancient books have no use value for us, if they are broken, they will be broken, there is no need to pick them up." Xiang Hanyu stopped Quiet Treasure from continuing to salvage the fragments of the ancient book, and threw all the remaining ancient books in his hand into the water, and said with deep feelings.

Hearing Xiang Hanyu's tone, Jing Bao had no choice but to stop salvage, and said helplessly: "Also, we may not be able to get out alive, what's the use of ancient books." ”

"There is no endless road, we will definitely get out alive. Until the last moment, none of us can afford to give up on escaping. I just said that ancient books are useless, not because we don't have a chance to get out alive, but because I already have the secret to cracking the mechanism in the book, so the book is useless. Xiang Hanyu looked at Quiet Bao with a firm look in his eyes and said.

"What? Have you memorized all the secrets in such a thick book? Didn't you just flip through it? Quiet Bao said as he stared at Hanyu incredulously.

"How could I be so smart to memorize a book in just a few minutes. Just now you accidentally discovered that the fluorescent characters that were displayed after the ancient book was wet are the real secret to cracking the mechanism. You know, in fact, the secret is only seven words - today you are going to marry me. Xiang Hanyu pointed to the fragments of ancient books that had almost disappeared in the water, and said faintly with some fluorescent characters.

"Ahh Such a strange secret! What does that mean? Quiet Bao asked puzzled.

"I don't know at the moment, but I can only understand why when I enter the tower called Life and Death Love in the future. However, it's a bit early to say this, and the top priority is to find a way to get out of here and find Big Brother and Feifei. Xiang Hanyu also felt a little strange and said, he couldn't figure out why such a simple secret could actually crack all the mechanisms in a tower.

However, he didn't want to delve into the secret here, and began to look around again, looking for a way to get out of here safely.

Since there is no secret passage in the stone house, you can only return the same way, but if you want to swim back the same way, you must solve the problem of breathing in the water.

The ideal way is to have an oxygen tank, but for the two of them at the moment, it is undoubtedly impossible to have an oxygen tank.

Just as Xiang Hanyu was staring into the water, thinking about how to solve the problem of breathing in the water, he accidentally saw the body fragments of a glowing fish sinking in the water and slowly floating over.

This fragment is supposed to be left by the fish that was crushed by the stone gate of the stone house before, and Xiang Hanyu found that there were bubbles in the minced flesh of this fish, and the bubbles quickly burst when they surfaced on the water.

Xiang Hanyu bent down and brought his nose close to the bubble, sniffed it carefully, inhaled it a few more times, and immediately felt very comfortable.

This feeling is very familiar, and it is this smell of gas that comes out of the oxygen that he used to use.

Oxygen is bought by his mother for him to stay up late to review his homework, which can automatically produce oxygen, inhale it for a while, and can also relieve brain fatigue and relieve study pressure.

Sniffing and sniffing, Xiang Hanyu suddenly had a bold idea, and he suddenly crouched down and completely submerged himself in the water.

After exhaling all the air in his mouth, he grabbed a glowing fish in the water, stuffed it into his mouth, and bit the fish in half with his teeth.

Soon the liquid in the fish's body and the water in his mouth mixed together, and many bubbles were instantly formed, and after about a few seconds, there was no water in his mouth at all, and everything turned into gas.

Xiang Hanyu tried to slowly inhale the gas into the trachea, and found that it was oxygen.

After this oxygen was inhaled, Xiang Hanyu felt much more comfortable all over his body, and after inhaling for a while, he expelled the carbon dioxide from his lungs through his nose.

He just sucked in his mouth and lined up his nose, and when he felt that there was not much oxygen, he chewed the fish meat back and forth in his mouth, and a large amount of oxygen was produced.

Before he knew it, he dived in the water for more than ten minutes before he got up from the water.

As soon as he left the water, he spit out the body of the fish in his mouth and took a look, and found that half of it was still uneaten, which means that as long as he chewed the body of this fish slowly, he could completely solve the problem of breathing in the water.

Based on the experience just now, Xiang Hanyu was sure that half a fish in his mouth would be able to stay in the water for at least half an hour, so that they would have a chance to return the way they came.

Now the only question is whether Jing Bao, as a girl, dares to bite off the fish in her mouth directly, in case she vomits in the water because of nausea, once she chokes on the water, it will be very dangerous.

Xiang Hanyu caught another fish and handed it to Quiet Bao, asking her to try it first to see if she could accept this way of breathing in water. If it really doesn't work, he will think of another way.

Jing Bao hesitated for a moment, not daring to take the fish, because she really didn't dare to do it. But considering that if she didn't do this, she would be trapped here, and a little unwilling, after thinking for a while, she gritted her teeth and took the fish, squatted down and dived into the water completely.

After spitting out the air in his mouth, he put the fish in his mouth with trembling hands and bit it hard.

Just when Jing Jingbao was worried that he would be disgusting, he found that there was no fishy and unpleasant taste in his mouth, but it felt very cool, and there was a hint of sweetness.

When there was a lot of gas in her mouth, she tried to take a breath, and the feeling of holding her breath disappeared, and she could actually breathe.

Jing Bao was overjoyed, exhaled back and forth in the water, and tried to slowly chew the fish meat to get more oxygen, trained for a while, and finally got used to it, before standing up.

Seeing that Quiet Treasure could accept this way, Xiang Hanyu also breathed a sigh of relief, so the two of them each caught a larger glowing fish, looked at each other firmly, and walked hand in hand towards the entrance of the passage hole.

At the edge of the hole, considering that Quiet Po is not a good swimmer, Xiang Hanyu put his arm around her waist and motioned for her to hold her breath and not panic.

After making sure that Quiet Treasure was ready, Xiang Hanyu also took a deep breath and jumped into the deep passage with Quiet Treasure in his arms.

After entering the passage, Xiang Hanyu hugged Quiet Treasure tightly and dived down at full speed.

When they swam to the cave where they had met before, they both stuffed the fish in their mouths together, took a bite, adjusted their breathing, and then continued to swim quickly along the passage with Hanyu around Quiet Treasure's waist.

Along the way, they had a clear view because of the many glowing fish, and every time they encountered a three-way intersection, Xiang Hanyu still chose to turn right and continue to move forward.

After about twenty or thirty turns, they finally swam to a deep pool mouth, the edge of the deep pool mouth is inlaid with countless night pearls, and the cave where this deep pool mouth is located is also inlaid with night pearls everywhere, so the cave is very bright, and everything can be seen very clearly.

In front of the deep pool, there is a waterfall rushing down, and the water of the waterfall is full of glowing fish.
