Originally, thinking of her younger brother's situation made Tan Xin a little excited, but seeing the scene below at this moment, she also retracted her thoughts.

"It's ......," she looked at Pu Yang in disbelief.

Pu Yang smiled: "Underground river." From a scientific point of view, the formation of sinkholes is often due to the turbulent underground river underneath, which constantly washes and causes the mud layer to sink and then be washed away. It may be that when there is a big flood in decades and hundreds of years, it will penetrate and sink once, and it will have such a spectacular height in hundreds of thousands or millions of years. ”

"There are dozens of sinkholes here, which is also very normal, the geographical environment of the same area will be affected, and there will be different degrees of subsidence, which will form sinkholes of different depths. If this continues, perhaps in tens of thousands or hundreds of thousands of years, as these sinkholes continue to sink, this area may fall into the sinkhole, and eventually form a huge sinkhole. ”

Tan Xin was surprised for a while, because she was a member of the Tan family, this is a forbidden place that has known the Tao since she was a child, and there have been many legends, which are generally told that it is a blessed place discovered by the ancestors of the Tan family. So she didn't think about it from the perspective of geographical common sense, and now listening to Pu Yang, it makes sense to think about it.

"But...... It is understandable that such an environment is used to train young children, but why do you say that there may be various gains underneath the undeveloped sinkhole? ”

Pu Yang thought for a while, "It's still about time!" Qiantan Mountain is not a famous mountain and river, but as the resources become more and more scarce, the famous mountains and rivers have been mined, and there are many nameless hills, and there will be people to try their luck. That's how your ancestors probably came here, and there must have been others before them. There are any spar elixirs, they have all been taken away. The sinkhole has certain difficulties and dangers because of the difficulty and danger of going down, and the deeper it is, the better the preservation. ”

This sinkhole was not formed in a day, but over decades, millions, or even tens of millions of years. Therefore, it is completely possible to use the hundred-year-old and thousand-year-old elixir at every stage. The deeper and longer you go, the more likely you are to have more.

Tan Xin nodded, remembering what was going on. "You said my brother...... Could it be that he fell into this underground river, so there is no way to hold on to the rope anymore, and there is no way to use the walkie-talkie? ”

"Possibly! The walkie-talkie might have broken when it went into the water, and he couldn't even explain the situation to the top of the radio. Moreover, the underground river seemed to be very urgent, and there was no sound, and he came down suddenly, and he might have been washed away before he could react. ”

"So...... Is it possible that the Far Tree is still alive? Tan Xin was filled with hope, and since she came back, she had been depressed until she saw her mother's corpse at its highest point, and now there was finally a good signal.

Pu Yang nodded, "Not bad!" ”

This is just comfort, in fact, he is not very optimistic in his heart. I don't know how many kilometers or 10,000 meters of underground river the road is, I don't know what the temperature of the road is, I don't know how the pressure of the road is, and I don't know if there are extinct aquatic organisms living on the surface of the road, but what can be determined is that there is no day below, the water flow is turbulent, and after this little bit of space, I don't know where the road can be exited again.

In such a situation, perhaps the super powerhouse of the Dao Realm will have a great headache, and it may be difficult to get out of the Void Realm, or even the peak of the Void Realm. And Tan Yuanshu is just a young man who came out to practice, with his cultivation, he can't last long at all, he may suffocate or drown due to lack of oxygen, so that in the intricate depths of the underground river, even the body may not be found.

Tan Xin was a little excited at first after hearing this, but then slowly fell silent and thought of this layer.

"I'm going to find him!" Although she knew that her younger brother would die for life, even if she went down, it would be very dangerous, but she still made a firm decision. Like her mother, even if she knows that she can't do it, she still wants to try, because if she doesn't try, she will give up, and if she trys, there is at least a glimmer of hope.

Pu Yang had no accident, nor did he persuade her anything, just a simple sentence: "I'll accompany you." ”

Tan Xin's heart was full of gratitude, for Puyang, she knew that she didn't need to thank her verbally, she had already given her all her heart and soul before. But at this time, she still has to refuse!

"No, you can't come with me. My mother is gone, and my brother may be ...... If I die down there, it won't make a difference. You are different, you still have your family, and Miss Qin, you still have the arduous responsibility of protecting mankind. You go back first, you don't have to wait for me at the Tan family, if I can come back, I will naturally look for you. ”

She let her tone be very resolute, but when it came to the end, she couldn't help but shed tears.

"Puyang, thank you! Xie Lu Xie let me meet you, although we were not happy at first, but in the last few months, I am really happy and satisfied. I die without regrets! ”

This is her heartfelt words, thinking that when she was in Qiantanshan Resort, she and An Ningning were Pu Yang's together, or they were each other's wrong ones. At that time, she felt very humiliated and depressed, and when the family made her commit to Puyang, she felt that her life was very gloomy, and she felt that this life was destined to be without glory.

At that time, she was already planning to be a thoughtless walking corpse herself, go to Puyang's side, and be his × slave, whatever he wants. I didn't expect the result to be completely different, Puyang gave her respect and gave her a new life.

Among them, she also encountered dangers, but in general, the days with Puyang were thrilling and colorful, and Qin Yao, Ma Xiaozhu, and Xiaobai were all very kind to her, so that in addition to An Ningning, she had some real and uninterested friends.

In such a life, of course she doesn't want to die, she has also broken through the level of virtual realm, how can she be willing to die? When she came back this time, she also thought about taking her brother out of the Tan family if she was not happy at home. I didn't expect it to be such an ending!

"Don't be stupid, how can you live in this water without me with you? I couldn't even find the direction, so I really died. Pu Yang deliberately smiled lightly.

Tan Xin, who was in tears, shook her head vigorously: "No! I must not let you go down with me, if it affects you...... I'm really going to be the ominous person they call it, and I'm going to kill you again......"

Pu Yang couldn't cry or laugh, but she didn't expect that at this time, she also thought of this rumor. Her mother's death convinced her of this, and if she wanted to break the curse, she had to help her get her brother back. But that hope was slim, and she was sure to go down and find it.

After thinking for a while, Pu Yang deliberately said strongly: "Even if you are your father, my mother, my brother, I am not your husband, didn't you say that I would be my slave girl?" I am your master, and this life is certainly harder than yours! Now is not the time for you to arrange, it is for me to call the shots. You have to do what I, the master, do! ”

Tan Xin couldn't stop her tears, she knew very well that Pu Yang said this on purpose, so that she had no reason to refuse.

Pu Yang didn't give her a chance to refuse, put away the flames, took out Xiaobai's Night Pearl that was still hidden in him from the Dzi space, and put it into Tan Xin's hand.

"Put away the sword, take this!"

He found a "guide talisman" by himself, and pasted the talisman on the cliff wall to locate the way back. Then he hugged Tan Xin, performed a trick to avoid water, and sank directly into the turbulent underground river.

It's already like this, Tan Xin can only wipe away her tears and make herself strong and tenacious, she told herself that she must not hold back, and she must not let Puyang suffer any harm, otherwise she will not be able to forgive herself.

Sinking into the underground river, Tan Xin really lost her sense of direction completely.

Puyang is much better, he has had the experience of being at the bottom of the West Lake, and he has also had the experience of being in the sea. Even this morning, I was teleported from Penglai to the sea, and then I took them all ashore together.

In such a dark underground river, the Night Pearl also supports the environment that brings light to their surroundings and gives people a little bit of habit. It is unrealistic to really use the light road, Pu Yang hugged Tan Xin and walked forward in the direction of the river, and at the same time, he spread his divine thoughts, and there was a detailed feeling around him.

The underground river is not large, but it is a bit of a stretch, and many of them converge from above, which feels a bit like being washed by a small waterfall.

They are here to look for the Tanyuan tree, and the Tanyuan tree can't do it against the current or find a way by itself, so it must only be washed out with the current, so Puyang sensed that there was nothing unusual nearby, and there were no living creatures, but it was also inconvenient to accelerate, so he could only go along the river.

Such a process, I don't know when the road will be the end, in fact, it is quite boring. In order not to make Tan Xin sad, Pu Yang also took the opportunity to explain some things to her, such as learning the spell of avoiding water, and trying to use divine thoughts. Like she already has the level of the Shroud, these skills can be tried to develop.

I don't know how long it took to say that Tan Xin noticed that Pu Yang's expression was a little serious, and she hurriedly asked in a low voice, "What's wrong?" ”

Pu Yang shook his head, "I suspect that we are about to be washed away, in addition to the fact that the water is getting slower and slower, I also feel that there is a powerful existence in front of me...... I don't know what it is. ”

Tan Xin's spirit perked up, no matter what, if it came to an end, it meant that his younger brother was also rushed here, so even if it was a few days ago, he should be able to find it. Take a step back and say, even if you die, you have to find the body!

Puyang sensed the changes around him, and felt that the river had become very spacious, or should it be said that the underground river that came along the way merged into an underground lake, and it is unknown how big it is.

After a while, he felt that he was floating, there was air around him, and he no longer had to avoid the water, he held Tan Xin in one hand, and the two of them could fly slowly on the water.

"It's ...... A big cave? No, no, it's underground......" Tan Xin didn't know how to describe what she saw now.
