There was the sound of water, like a trickle, and the sound of tinkling resounded in this hole. It was already close, Zhang Yang threw a small stone, bounced it on the cave wall a few times, and fell into the water with a pop.

The two entered a large underground water channel, and the rushing water stirred up on the raised rock, swirled and drilled through. Fortunately, it was not all water, so the two of them found a rock to settle on and stopped.

Qing Kui pulled back her water-soaked hair, the environment here made her body cheer, and the water aura was so strong that it wanted to burrow into her every pore. There was not a single surface water to be seen in the entire Crucible Mountains, but there was such a raging vein of underground water hidden in the depths of the earth.

Zhang Yang picked up a puddle of water, the water quality was very clear and very cold. "The water temperature here is still very low, what happened to the fountain before?" he spilled the water in his hand back into the river, and a small transparent fish swimming upstream against the current seemed to be frightened, and its tail turned around with a sharp turn, and it disappeared in an instant with the current.

As if to confirm his words, there was a rumbling whistling sound from the passage upstream, and a trace of hot air first penetrated his nose, the peculiar smell of hot spring water. The dark passage roared at them like a giant beast with its jaws open. The thin spray of heat slapped Zhang Yang in the face.

"Senior sister, we are going to be boiled......" Zhang Yang said helplessly, although with his physical strength, boiling water could not cause him harm, but the taste was definitely unpleasant.

"There's a senior sister here, don't worry. As he spoke, he pulled up Zhang Yang and jumped down from the river.

Zhang Yang has a deep memory of diving, but this time there are beauties pulling and jumping together, but I feel that the jump is a little less tragic and a little more panicked. The expected awkward entry into the water did not happen, and the place where the two of them were became a cavity, falling to the bottom of the river, and the hot water rushed over their heads. The water was about forty meters deep, and soon they were at the bottom of the river. Zhang Yang curiously poked his finger at the water flow in front of him as if blocked by an invisible wall, and stretched out without any obstruction. A swimming fish crashed into the bubble and fell directly on the mud and sand at the bottom of the river, flapping and fluttering with its tail. Qing Kui chuckled lightly and pulled Zhang Yang forward a few steps, and the fish was submerged in the water again and swam away in a hurry.

As he walked, Zhang Yang felt that the temperature around him was getting colder and colder, definitely below freezing, and the water around him did not freeze because of the flow. "It's close. ”

There was a dim light not far away, although it was only a hint, but it was quite dazzling in this dark environment. A table-sized block of ice lies quietly at the bottom of the lake, glowing pale blue, reflecting a dreamy pattern on the riverbed.

"It's beautiful. Qing Kui touched the surface of the ice cube and muttered.

Under her touch, the ice cube changed somewhat. Bang, like the beating sound of a heart. A blue flame appeared in the center of the ice, pulsing slowly.

Under the beating of this flame, Zhang Yang felt that the aura in his body also fluctuated one after another, and a strange cold penetrated his body, and the black aura in his body seemed to feel provoked, and in the blink of an eye, the invading strange cold was shattered.

Qing Kui turned into an ice sculpture at the moment, her face was covered with frost, and her hands were still motionless on the ice.

"Senior sister, are you okay?" Zhang Yang asked eagerly, he wanted to remove Qing Kui's hand on the ice, but that hand seemed to have become one with the ice. He quickly took out the Dry Bone Knife to smash the evil ice.

At this time, Qing Kui's voice sounded in his heart: "Zhang Yang, I'm fine, this strange thing is the essence of Xuanshui, which is of great benefit to me, but it is difficult to refine for a while, so I have to make you wait for a while." ”

When Zhang Yang heard this, his heart relaxed, and he sat on the side to guard her, occasionally glancing at her face as clear as ice crystals.

I don't know how long later, there was a low vibration in the riverbed beneath my feet, and the mirror-like water around me also stirred up a circle of complex ripples, like the palm prints of giants. Zhang Yang stood up and looked around uneasily.

A huge shadow appeared at the bottom of the dark water in the distance, floating back and forth like a swimming fish, and two lantern-sized spots of light blue light shone brightly, Zhang Yang knew that they were the eyes of demon beasts.

Zhang Yang put the dry bone knife in front of him and protected Qingkui behind him. "Senior sister, the demon beast is here. At this time, Qingkui did not respond.

The demon beast quickly swam in front of Zhang Yang, its huge head stopped outside the cavity, the demon beast seemed to be an infinitely magnified salamander, and its skin was covered with warts the size of bean grains, it stopped there, staring at the two people in the cavity motionlessly. The hairs on Zhang Yang's whole body exploded, and the unknown demon beast in front of him brought him a strong sense of danger, and the huge figure looked even more terrifying under the dark water.

When the monster saw the green sunflower next to the ice block, it suddenly became angry, as if the green sunflower was snatching what originally belonged to it. It opened its massive mouth, its massive face seemed to split in two, and a low voice came from its mouth. The vibration under his feet was countless times stronger than just now, and the mud and sand at the bottom of the river became like waves under this strong agitation. This roar like a low engine made Zhang Yang extremely uncomfortable, he seemed to have returned to the school field of Qianyuan City, but the attack of the demon beast in front of him was countless times stronger than Liu Baolong's magic weapon.

The next moment, the empty bubble that wrapped the two of them shattered under the impact of this terrifying sound wave, and the surrounding water rushed over at once, drowning the two of them.

Zhang Yang struggled to swing the Dry Bone Knife at the demon beast, but the strength was greatly reduced in the water's blockage, and only a small cut was made on the demon beast's chin. The wound was not to be feared, but the thunder and lightning on the knife made it hurt, and its body swam to the side, staring at Zhang Yang cautiously.

This is exactly what Zhang Yang wants, and being too close to Qingkui will inevitably hurt her by mistake. Seeing that the demon beast swam away, he hurriedly greeted it, and was about to use thunder on the demon beast.

But nothing happened. The expected lightning did not appear, and the water acted as a conductor to completely disperse the energy of the electricity, and lightning could not appear. The environment here is very unfavorable to him, and the resistance and characteristics of the water make him untenable.

The demon beast seemed to be very sensitive to electricity, and it was provoked by this subtle electric shock, and it rushed towards Zhang Yang with its mouth open, and the previous sonic attack came out from its mouth. Zhang Yang was stunned by the impact of this sound wave, he tried to hold back the feeling of vomiting, but the next moment he was bitten by the demon beast. The demon beast's mouth was full of fine small fangs, although it was not very long, but it ploughed out two terrible wounds on Zhang Yang's chest, abdomen and back in a bite, and blood overflowed and permeated into the water.

He didn't panic, he held the dry bone knife with his backhand, and sent the slender blade into the upper jaw of the demon beast, and Lei Man released it frantically. "Whew!" the monster howled, and the cry was unpleasant. The top of its mouth was already charred black, its body writhed violently, and with a sudden flick, it threw Zhang Yang to the rocks at the bottom of the river, and the dry bone knife in his hand was also taken off.

"Whew!" the demon beast roared at Zhang Yang, compared to the previous attack, this time the sound wave was more targeted, the water in front of Zhang Yang was distorted, this strong sound wave attack was like a hammer on Zhang Yang's head, and his eyes were blank for a while. He felt a fishy nose and mouth, and spat out a mouthful of blood. The attack took a heavy toll on his spirit, leaving him to languish.

Zhang Yang wanted to get up, but his body was a little disobedient. I tried twice, but I fell back into the sand. When the demon beast saw Zhang Yang's appearance, it stopped paying attention to him, and turned around and swam towards Qingkui.
