Nowadays, the climate of the Northern Xuan Domain is also in summer, because there are rocks and soil in the air, and the soil layer prevents the heat from entering, making it extremely shady under the abyss.

There's nothing special about the cave, it's like it's inside a huge crust. Tang Feng was careless, and after taking a slight turn in the cave, he wondered about the machine spirit: "I've finished reading this, it doesn't seem to be anything special, I'm going back to cultivate!"

There were only twenty-five places to enter the Beast Cave, and counting the absorption of the four Gu Tie Xia Yan, the Heaven and Earth Spirit Yuan Qi of the entire Cave was also rapidly depleted. How could Tang Feng not be anxious this time? If he had waited for a few hours after the energy was depleted, wouldn't he have been blind in the battle he had fought in the past two days?

"You kid, can you stop being so blind?"

Hearing Tang Feng's words, the machine spirit said with some hatred: "As the Xuanwu clan of the divine beast lineage, even if it is full of treasures again, and the divine beast lineage has a common characteristic, that is, they will leave a treasure no matter where they live. The Xuanwu clan is even more cautious!"

"Compared to the rest of the divine beast branches, the Xuanwu clan is also thinking long-term. In order to face unprepared needs in the future, there will definitely be a backhand here! Otherwise, will you think that the once-triennial spiritual yuan gushing is natural? If you find the source, how much will you care about these momentary outpouring of spiritual power?"

"However, this beast cave is so huge, are you sure it must be in this cave?" Tang Feng asked with his eyelids drooping slightly.

"Don't forget who I am. ”

Hearing this, the machine spirit smiled with relief: "As early as when I entered the beast cave, I had already noticed a unique fluctuation that existed here, and all the heaven and earth spirit yuan qi in the beast cave also came from here, but I haven't discovered it yet." ”

"Well, I'm looking. Tang Feng resisted the urge to absorb the Qi of the Spirit Yuan, and once again observed carefully in the cave.

Although the machine spirit has a lot of confidence, after Tang Feng searched back and forth and carefully searched for a few rounds, he was also a little drumming, and when he saw that the spiritual energy was consumed extremely quickly, he said weakly: "Or, you absorb it first, and then you are looking for it after absorbing it?"

"Forget it!"

Tang Feng almost got angry when he heard this, feeling the spirit yuan power that disappeared quickly, the latter shook his head and said, "Even if you absorb it, according to the current strength of the spirit yuan qi, it is far from enough for me to break through!"

Tang Feng was helpless, standing on a stone wall and feeling the weaker and weaker aura, he couldn't help but sigh, but at this moment, a trace of persistence was aroused in his heart! Looking at Xia Yan and Gu Tie, who were emitting a golden and majestic light in the open distance, Tang Feng knew that the former had both touched the threshold of the Shenyuan Realm, and would soon break through!

"Keep looking!"

Tang Feng gritted his teeth, squeezed out three words from the root of his teeth, and groped along the rock wall sullenly.

The cave is extremely wide, almost the size of a football field, Tang Feng thought that an hour had passed after carefully searching for a circle in the rock wall, at this moment the spirit yuan qi in the cave was disappearing at an extremely fast speed, here Gu Tie and Xia Yan were approaching the bottleneck of breakthrough, and Tang Feng was not good at absorbing and hindering the breakthrough of the two.

Chu Guang and Huang Rong, who were in the process of absorption, also got up one after another and gave up all the spirit yuan qi to the two of them.

Tang Feng exhaled heavily, and the voice of the machine spirit was even more silent, which couldn't help but make him pick up a green tendon on his forehead, but he didn't blame the machine spirit. Speaking of which, I was able to walk here from a small town of Wusha thanks to it.

"Boy, you hit this rock wall with your strength!"

Just when Tang Feng was in the mood to improve his cultivation for Gu Tie and Xia Yan, the voice of the machine spirit sounded again.

"What are you doing with it?" Tang Feng frowned when he heard this, and said, "I'm not going to hit something to vent when I'm angry, right?"

"Where is so much nonsense?" Hearing this, the machine spirit shouted directly: "It's hit!"

Tang Feng looked surprised, touched his fist as he did, and immediately punched the rock wall!

"Bang!"

A punch fell, and a cloud of dust was stirred up on the rock wall, and then a trace of labor pain came from Tang Feng's hand bones, and the wall was still intact, except for the dust, not even a single rock fell.

"It's so hard!"

Tang Feng couldn't help but exhale, he didn't expect this natural rock cave to be so strong, and he couldn't even move his own blow.

"Fight again, with all your might!" the machine spirit said.

Hearing this, Tang Feng clenched his fists, and even saw that the fist was covered with purple thunder and lightning light, without saying a word, he stepped forward, and the latter raised his fist and blasted out!

"Bang!"

At this time, a deafening explosion erupted in the entire cave, and in an instant, the corners of Tang Feng's mouth grinned, and a trace of pain spread all over his face, and when he looked at the intact rock wall, his eyes were completely frightened.

"What the is this rock wall, why is it so hard?" Tang Feng clenched his fists and gritted his teeth and cried out in pain.

"Hahaha, this isn't a rock wall. ”

Just after Tang Feng finished speaking, Huang Rong's small body shook step by step, and walked with a childish laughter, looking at the rock wall, his eyelids sank slightly, his eyes looked at the ceiling from the rock wall, and after rotating around from the ceiling, after half a sound, Huang Rong said with a little surprise: "What a big king eight shells! I'm afraid this thing must be a Xuanwu giant tortoise, right?"

"Wang Bahu?"

Tang Feng was stunned when he heard this, and glanced at the empty cave according to the trajectory of his desolate gaze just now, his eyes were a little dull, and after half a sound, his dark pupils shrank tightly, and he exclaimed: "What do you mean, this cave is ......?"

"That's right, this cave is a tortoise shell. We are in this turtle shell at the moment. At this time, the machine spirit said luckily: "I didn't expect to encounter such a huge turtle shell here, no wonder I couldn't find anything strange just now." ”

After listening to the words of the machine spirit, Tang Feng was a little confused, and when he heard that this cave was formed by a turtle shell, he was even more shocked and couldn't speak, and after coming back to his senses, he hurriedly asked, "What is the use of such a big turtle shell for us?"

"It's so useful!"

Huang Rong exclaimed with some joy on the side: "The shell of this Xuanwu giant turtle is very tough, just take off a fist-sized turtle shell fragment is enough to create a god-level defensive treasure! Not to mention an intact turtle shell?"

"Didn't I send it?"

Tang Feng looked at the cave with a diameter of more than 100 zhang in a daze, and immediately his eyes turned red, if he took out this material and bought it, the resources he exchanged for it would be extremely huge!

"It's haired, but it can't be sold!" The machine spirit naturally knew what Tang Feng lacked the most, and he also knew what he was thinking at the moment.

"This complete tortoise shell is a rare material, and it may be of great use in the future. And if you take this kind of thing out and sell it, you can only sell it once or twice, and if you sell it too many times, you will be remembered by everyone! Moreover, the main purpose now is not on this turtle shell, what you are looking for is the basalt turtle pattern. At the end of the sentence, the voice of the machine spirit became a little hot.

"What's that?"

Tang Feng's vision was only limited to the Yuehua Continent, and he was in the stage of being a novice in anything in the Northern Xuan Domain.

"The Xuanwu Turtle Pattern can only be found on the complete turtle shell, which has the essence blood of the Xuanwu lineage, which is extremely rare, if you can melt it, it will be of great benefit to your strength! Of course, the benefits are not only that. ”

"Where can I find the tortoise pattern?" Listening to the words of the machine spirit, Tang Feng's eyes had already become scorching.

"Directly above the turtle shell, if this is really a Xuanwu giant tortoise, then there must be a blood pattern in the center of the turtle shell, where is the place for the treasure!"

"Straight up. ”

As he spoke, Tang Feng's eyelids lifted and he looked at the passage in the distance, his figure gradually floating. With a figure passing by, Tang Feng quickly ran out of the cave.

When he came to the passage, he looked at the surrounding rock wall, the latter held his palm, and the purple gold thunder emperor spear also appeared in an instant, and then the body of the spear rotated rapidly, drilling a narrow tunnel in the rock wall. His own body is also submerged in it.

Inside the vast beast cave.

The three elders of the Moon Shadow Hall and the others had already discovered Tang Feng's disappearance, and several elders were also full of anxiety about this, but they couldn't care too much about the tempting spirit energy of heaven and earth in front of them, so they had to use the jade plate of communication in the hall to inform the great elders waiting outside the beast cave about the matter.

The latter received the report from the three elders, and his face was instantly solemn, and Fandel's stomach was full of sorrow. At this time, in the past two days of fighting, Tang Feng's strength far exceeded the imagination of the Great Elder, and he was also a person who tried his best to win over, and he didn't want to see anything happen to the former.

Hearing what the third elder said, she also looked at the entrance of the cave with some anxiety, hoping that Tang Fengji people had their own natural appearance, although there was not much danger in the beast cave, but it was more complicated than the labyrinth, and if she accidentally lost her way, it was very likely that she would never get out again.

Outside the Beast Cave, it seemed extremely peaceful under the moonlight, and the rest of the forces sat patiently on the stone pier or grass waiting for their own people.

However, among these many people, they were stunned to see the people of the Dunchengxi faction, and no one even noticed when they disappeared.

When they came back to their senses, everyone didn't care, and the Western faction left a deacon who entered the grotto and disappeared by himself, afraid that it was also because he fell behind in the last game and was in no mood to stay here any longer.

"Boom!"

At this moment, when no one smelled a trace of weirdness about the disappearance of the Western Sect, a scorching light swept across the sky in vain and fell vertically from the sky. The sudden explosion shook everyone around the cave, and they immediately flew into the sky.

Immediately, everyone frowned, and looked up at the sky with solemn faces. Under the quiet night sky, more than 20 people wearing black robes and covering their heads and faces slowly flew down.

Looking at the black-robed man who suddenly appeared, the eight forces were also shocked in their hearts, and there were more than twenty people in front of them, all carrying an extremely huge energy fluctuation!

"Dare to sneak attack, dare to sneak attack, report your name!" an elder of the Shogunate City shouted angrily in vain.

"Registration is free. ”

A black-robed man in the lead laughed gloomily under the face that couldn't see clearly: "Because today, you are all going to fall here!"

As soon as the words fell, an extremely majestic yin aura instantly diffused, and the black yuan force shrouded the entire night sky, under that brutal yuan force, the entire river basin was a shade, like falling into an ice cave, and the killing intent in it was even more bloody and terrifying......

"All the male monks have slaughtered and taken out the inner dan, and the female monks have tied them up for me!"

After the leader of the black-robed man finished speaking, the eyes of the subordinates behind him were cold and piercing, and they all roared out with monstrous killing intent......
