In the early hours of the morning, Zi Su returned to the waterhole, only to find that Zi Yun and Yu Feng had come up from the underground river.

Yu Feng saw Zisu and asked him why he went, and Zisu said that he had made a big deal tonight.

For a warrior, the big deal can refer to many actions, but the biggest deal is nothing more than killing.

Ziyun asked what kind of big deal it was, and Zi Su replied that it was naturally a murderous business, saying that he had killed nearly 200 people in one fell swoop with his Loose Demon Sound, and wiped out all the hostile forces that had invaded the underground palace.

Yu Feng and Zi Yun looked at each other and asked when so many enemies came in the underground palace, Zi Su said that all this was done by the white horse and black god Heiren in the back, but this time the Hei family suffered heavy losses and died at least dozens of elite-level dead soldiers, but unfortunately they were run away by Heiren.

Yu Feng pouted and said, "Why don't you call me and Ziyun if you have such a good deal." ”

Zi Su smiled and said that he launched a magic sound attack, if they made a move, I am afraid they would have to find the enemy, that would be too troublesome, Yu Feng thought about it, the terrain of the underground palace is so complicated, it takes a long time to find someone, it is better to launch a sonic attack directly like Zisu, which can reduce the unnecessary link of finding people.

Zi Su also talked about the fact that the exit of the underground palace was closed by Heiren's design, Yu Feng said that he would simply go to the underground dark river, and Zi Yun said that the situation of the underground dark river was unknown and he needed to prepare in advance.

"The big turtle should be more familiar, in fact, you can ask it about the specific situation first, and then we can explore the way, and then we can let it lead the way. ”

The three of them returned to the underground dark river, and Shisu communicated with the big old turtle and asked him to lead the way in front, and the big old turtle agreed, but it said that the underground dark river has two exits, one is in the Xuanyin River at the foot of the Xuanyin Mountain Range, and the other is in the Xuanyin ** library near the Xuanyin Demon Sect ruins.

The location he agreed with the old devil was in the Xuanyin Demon Sect, so it was necessary to be familiar with the route of the Xuan** library, and when the time came, he could rely on this secret line to quietly appear, so that the old devil was caught off guard.

"Big old turtle, we will go to the line of the Xuan** library this time. ”

"Master, there was nothing wrong with taking this route, but ten years ago, a big crocodile appeared in the underground dark river, and it was my old opponent, so he hid in the underground dark river and was ready to attack the old turtle at any time. ”

"Yes, don't worry, as long as it dares to appear, we will take advantage of this exploration to destroy it. ”

"Yes, if it dares to appear, we will destroy it. Yu Feng echoed and said with a smile, "To be honest, I haven't seen a big crocodile yet." ”

Shisu has seen a lot of fierce beasts, including the big crocodile, he said with a smile: "Actually, the big crocodile is not difficult to deal with, but the big crocodile that can fight with the big old turtle should still be quite powerful." ”

After the preparations were made, the big turtle led the three of them into the water.

The back of the big turtle is very slippery, and there is no place to grasp it, only to grasp its neck, otherwise it will be easily washed away by the current in the swirling nest or torrent of the underground dark river.

Zi Su sat at the front and grabbed the neck of the big old turtle, Zi Yun sat in the middle and hugged Zi Su's waist, Yu Feng hugged Zi Yun's waist after it was broken, and the three of them clinged to the turtle's back.

"Big old turtle, action. ”

"Yes, master. ”

The big turtle took the three of them to swim into the entrance of the underground river, and the underground river was very quiet at first, which is probably another reason why the big turtle chose to retreat here.

However, after turning a dark river, the front was suddenly turbulent, and the torrent was bursting, if it weren't for a behemoth like the big old turtle, I am afraid that it would be easily swept away by the torrent.

The old turtle swam uphill in the rapids, turning several bends before the front became calm again.

"Master, the big crocodile is just ahead. ”

Shiso said, "Big old turtle, I feel its voice. Ziyun, give me the Bloodthirsty Dragon Sword. ”

Ziyun replied, "Yes, young master." She handed over the Bloodthirsty Dragon Sword, and after Shisu took it, she swam towards a black behemoth in the distance, training to catch fish under the water, so that he could now swim as fast as lightning.

"I have a sword that can shake mountains and rivers. Without getting closer, Shisu suddenly cast the Dragon Blood Divine Sword Technique, and the powerful sword qi rushed directly towards the big crocodile lying still.

The big crocodile didn't expect a human to have such a fierce offensive ability, and it was immediately cut by the dragon's blood sword qi in the lower abdomen, causing it to tumble in the water.

The Bloodthirsty Dragon Sword has a bloodthirsty special effect, and once it is injured, it will bleed endlessly.

At this time, the big crocodile was full of ferocity, opened its big mouth, roared and pounced on Shisu.

Shisu was not in a hurry, turned sideways in the water, avoided its blow, and turned around with another sword.

"I have two swords, which can break the Yangtze River. The horizontal sword qi directly cut the abdomen of the predator, and it rolled violently in the water in pain, at this time, Yu Feng held the bronze man in his hand, and slammed it towards the head of the big crocodile, although the head of the big crocodile was hard, but how could it resist the power of the eight-winged phoenix, and the skull was shattered, and the old turtle was amazed in his heart, so violent human woman, this time the big crocodile may not be able to die anymore.

"Oh yes, call it a day. ”

Zi Su shook his head and said, "Fengfeng, you are too simple and rude like this." ”

Yu Feng smiled: "It's cool to be simple and rude." ”

At this time, the big old turtle said: "Master, the big crocodile has Neidan in its body, and that thing is a good thing for the old turtle." ”

"Oh, you want to devour the big crocodile's Nedan, well, I'll dig it out for you. He changed the dragon sword, cut the lower belly of the big crocodile with a sword, dug out the Neidan, and fed it into the mouth of the big turtle.

"Thank you hosts. While digesting Neidan, the big old turtle continued to carry the three of them on his back in the underground dark river, and after a full hour, a dark hole appeared in the dark river, and through the dark hole, the front suddenly brightened, and the belly of the mountain could be seen.

At this time, I really only heard the big old turtle say: "Master, the front will soon be at the bottom of the Xuan ** library." ”

"Okay, move on. ”

When the light became brighter and brighter, the big old turtle rushed through a spiral nest and entered the bottom of the Xuan** library.

"Young master, great, we're out!"

"Brother Shisu, it doesn't seem to be difficult. ”

"If there is no big turtle to lead the way, this underground river is no joke. ”

"That's right. ”

The three of them observed the terrain in the Xuan** Reservoir, and it turned out that this reservoir was only a few hundred meters away from the Demon Sect Ruins.

After staying near the reservoir for a while, the three of them can find the figure of the martial artist from time to time, it is better to stay here than to go back to the underground dark river, which is a good place to cultivate, and it can play a role in getting twice the result with half the effort, just like Ziyun, after practicing for one night, it is almost about to break through again.
