Hearing Zhou Zixuan's cry, long Tianci thought Zhou Zixuan was in danger. He rushed into the vertical shaft, looked up at the stairs and asked loudly, "sister Zixuan, what's the matter? You... Shit...! alas...!"

Just as long Tianci looked up at the stairs nervously, Zixuan had slipped down the stairs last week. The vertical axis was too narrow. Long Tianci didn't even have a place to hide. As a result, Zhou Zixuan, who fell down quickly, sat down on his face.

"Ouch...! my ass! It hurts so much!" Zhou Zixuan burst into tears when she fell down. Before, she slipped down four or five meters from the exit. The pain of butt rubbing against the stairs was not so good!

"Woo woo...!" while Zhou Zixuan was crying and complaining, the cruel hum of the Dragon God under her ass suddenly came out!

"Ah...? ah...!" Zhou Zixuan subconsciously lifted up her skirt and looked down. Then she found that long Tianci was sitting under her, almost subconsciously. Zhou Zixuan jumped up and hit her head on the low door frame!

"Hoo Hoo...! elder sister, do you want to suffocate me?" long Tianci, who sat up, gasped for breath and said to Zhou Zixuan.

Zhou Zixuan, whose head was knocked on the door frame, was covering her head and grinning. After hearing the words of long Tianci, Zhou Zixuan pursed her lips and said, "I didn't know you were below..."

"... forget it! Get out! It's too narrow here!" long Tianci looked at the tearful Zhou Zixuan and couldn't complain any more, so he stood up and raised his hand to push Zhou Zixuan out, and he walked out of the vertical axis!

As soon as she came out, Zhou Zixuan was stunned by the scene in front of her. Although the underground river is nothing new, such a large underground river is rare.

Looking at Zhou Zixuan's surprised expression, long Tianci said with a smile: "how? I said there must be an exit to the underground waterway?"

"OK...! are you great? But the water is so fast here, can we just drift down the water?" Zhou Zixuan turned her eyes when she heard what long Tianci said, and then asked!

"If we don't go on like this, how can we go on? We don't have a boat. Besides, the river channel of the underground river is full of reefs. Even if there is a boat here, it's difficult to control it. It's not good to finally hit the reef and it's dangerous." long Tianci answered with white eyes!

"... but I can't swim!" Zhou Zixuan finally said her heart. It turned out that she was afraid of water!

Hearing Zhou Zixuan's words, long Tianci rolled his eyes, then muttered, "such a big man can't swim. Aren't you ashamed? Forget it, I'll see what's available!"

After saying this, he raised his hand and touched the space ring twice in two days, and then closed his eyes. Obviously, he was looking for something useful in the space ring!

About a few minutes later, long Tianci suddenly smiled. Then he took out some strange translucent objects from the space ring and handed them to Zhou Zixuan: "blow this up!"

After receiving it, Zhou Zixuan smelled it, then frowned and asked, "what's this? How does it smell?"

"Boar's bladder...!" long Tianci replied casually!

"Ah? Bladder? I don't blow. It's too dirty!" Zhou Zixuan threw the things back to long Tianci and shook her head. The bladder is used to hold urine. How can he blow such dirty things with his mouth?

Long Tianci caught the bladder and turned his eyes, but he didn't talk any more. Instead, he began to blow by himself. Soon, long Tianci blew four and tied them with a rope. Then he tied these blown bladder to Zhou Zixuan's waist.

"Well! With these things, you won't sink, and then you'll just float down the water!" after finishing this, long Tianci tied himself and Zhou Zixuan with a rope, and then said!

Zhou Zixuan looked at the bladder tied to her waist with disgust, but she didn't complain any more. It was the only way to leave here. She could only endure it!

After finishing the preparation work, long Tianci and Zhou Zixuan jumped directly into the underground river. The turbulent water made them unable to control the direction. They could only float quickly to the west along the water.

It's not easy to float down all the way. There are many reefs in the water. Not far away, they hit the reefs again and again. Zhou Zixuan has a blown bladder as a shock absorber, so it's better. Long Tianci is suffering. Every impact makes him hum miserably, that is, relying on his own body, otherwise long Tianci would have fainted!

It floated far to the west along the water flow. The water flow suddenly became faster and the sound of the water became louder and louder. At first, they didn't understand what was going on, but they knew what was going on in a few seconds, because there was a waterfall in front of them!

They fell down the waterfall without any time to respond. Zhou Zixuan screamed and then fainted directly. Long Tianci was also flustered. His body was struggling in the air. Unfortunately, there was no place in the world and there was nothing to catch. In this way, they fell into the pool under the waterfall!

The powerful impact made long Tianci shoot seven meat and eight vegetables, and his head almost fainted. Fortunately, long Tianci was determined and kept awake. After entering the water, long Tianci quickly surfaced and looked around for Zhou Zixuan, but it was very dark here, and the water mist caused by the falling waterfall also seriously affected his vision, so long Tianci didn't find it at all!

In order to find Zhou Zixuan, long Tianci pulled up the rope that tied him and Zhou Zixuan, and began to pull back. It was not easy to pull Zhou Zixuan back to her, but Zhou Zixuan was unconscious at this time!

Dragging Zhou Zixuan, long Tianci swam to the shore, and then lay on the ground panting. The previous scene was too dangerous, that is, the two lives were big, otherwise it would be broken at this moment!

After lying on the ground and resting for a long time, long Tianci sat up and released Zhou Zixuan's bladder. Then long Tianci picked Zhou Zixuan up and stood up and began to look at the surrounding environment!

This place should also be a cave, with an area of about 300 square meters, and nine tenths of the more than 300 square meters are full of water. The river bank is very narrow. On the other side of the river bank, long Tianci sees a hole, and there is light outside the hole.

Seeing the light means that the hole leads to the outside. Long Tianci is very excited! He forgot his pain and rushed out of the hole with Zhou Zixuan in his arms.

At the moment when he rushed out of the hole, the dazzling light made long Tianci almost unable to open his eyes. The narrowed long Tianci looked up at the bright sky, and then shouted excitedly: "ha ha...! I'm out!"
