Dugu Yu returned to his shelter, a mouthful of blood spurted out, and the previous battle with the bald head made him more injured, and the already healed bones cracked again.

"It seems that it's better to be honest and recuperate first, I don't know anything about here, and a little more strength can be less dangerous. Although Dugu Yu didn't know the specific situation here, it could be seen from the bald head and Men Min from the previous that this place was by no means a good place.

Dugu Yu continued to consume spirit stones to supplement the previous losses.

"Although this chaotic aura is powerful, this consumption is also amazing. Duguyu thought helplessly.

Generally, the normal second-order Qi Refining Realm only needed one medium-grade spirit stone to restore the aura, but he had to consume ten, which was ten times more.

"The bald attack is very condensed, and the aura is almost not leaking, and it is not easy to do this. ”

Three days later, Duguyu finally recovered eighty percent on the premise of consuming two hemostatic pills.

"Yuan, what kind of existence is it?" Duguyu was secretly surprised while practicing.

The method recorded in the "Yuan" is similar to the previous use of true qi of the bald head, but the former can compress the true qi in a special way, which is much stronger than the application of the bald head.

"It's a bit hard to completely compress the power to a point!"

Duguyu kept failing, but he was not discouraged, and still tried little by little.

"It's almost there!" Dugu Yu's face revealed a sense of excitement, he had just successfully compressed a part of his true qi into a small slap, but with a distraction, his true qi instantly dissipated and returned to his body.

Three days have passed in the blink of an eye. On this day, Duguyu finally completed the final compression. Issei True Qi was successfully pressed to a point.

At this time, beads of sweat were dripping from his forehead, and it was obvious that it was extremely difficult to control at this time.

"I can't control it!" Dugu Yu didn't dare to take it back into his body again, but shot directly towards a cliff.

I saw an extremely condensed black dot shoot out from the tip of the sword at great speed, hitting the stone face of the cliff. Silently, the stones shattered into foam, the breeze blew, and a deep stone cave appeared in the stone wall. The surface of the cave is smooth and neat, as if it was cut and formed.

"It's really amazing!" Duguyu opened his mouth and said a sentence for a long time. He really didn't know how to describe this feeling, he wanted to carve a stone cave as a shelter before, but he only left a few sword marks on the stone wall, and now he unintentionally made such a big stone cave.

Duguyu cleaned out the stone powder inside, found that the hole was about a zhang deep, found some broken stones to build the hole to death, and sat down cross-legged to continue to understand the use of "Yuan".

"If I can apply the method of "Yuan" to my existing sword skills, then the power ......"

Just do it, the power compression range that Dugu Yu can fully control now is about the size of a baby's fist, and after the compression is completed, he grasps the hilt of the sword and draws the sword technique to unfold.

"Qiang"

"Boom"

After a loud bang, a hole the size of a human head instantly appeared in the inner wall of the cave.

"The power is not bad, this is still a state where I haven't really mastered the "Original", if I can compress the power to the extreme with every blow, I am afraid that I will dare to fight even if I am a strong man at the peak of the mountain moving realm. Duguyu thought confidently.

Next, Dugu Yu's consciousness sank into the Hongmeng space, and he needed to comprehend the laws of space as soon as possible, only in this way could Peng Mobu exert a real effect.

Duguyu, who had been immersed in the ocean of space all day, finally felt a slight spatial fluctuation after half a month.

"It's the law of space!" Duguyu was ecstatic in his heart, for fear that he would miss this rare opportunity, so he seized the time to continue to understand.

On this day, Duguyu finally woke up.

"Is this space?" he waved his hand, and a thin thread flew out.

"Click"

A crack appeared in the stone wall again, but this time the cut was extremely smooth, and it was not broken by brute force like last time.

"Since then, in addition to the chaotic aura, my Duguyu has two more hole cards. ”

"After the sword drawing technique is used with the "Yuan", it is no longer a simple sword drawing technique, it is better to call it splitting the ground, and the law of space with the sword technique is called slashing the sky. ”

Since then, Dugu Yu has two more talisman skills.

"It's time to go out and take a look, at least to find out what's going on with the Celestial Star Mine. ”

Dugu Yu was just about to get up when a voice sounded, and then, the gravel at the entrance of the cave was blasted open.

"Bang"

"It's a cave, and it looks like it's supposed to have been bombarded with some kind of force. There was a noise inside just now, and it was possible that some kind of treasure had been born. A voice slowly approached with excitement.

Dugu Yu hid his breath and made an instant move in the dark.

"Boom!"

"Adults spare their lives, adults spare their lives!"

Duguyu's iron sword was on the man's neck, so frightened that he quickly knelt on the ground and begged for mercy.

"I ask, you answer, if there is falsehood, my hand shakes, I am afraid that it will kill you. Dugu Yu deliberately lowered his voice, and a few words made the man tremble with fright.

"What kind of place is this?" Dugu Yu asked knowingly.

"This, this is the Tianxing Mine, where the criminals are held in Qianyuan Academy. The man thought that Duguyu was testing him, and quickly told everything he knew.

"Who are you detaining here?" Dugu Yu frowned and continued to ask.

"Most of the villains here are evil in the Qianyuan Continent, and after being captured alive by the Qianyuan Academy, they were all imprisoned here to fend for themselves. Among them, the Cult of the Underworld in the depths of the mine and the Thorn Society are the most powerful, and it is said that both forces have Emperor Realm powerhouses. There are also some subsidiary forces under the two major forces, most of which are strong in the Wang Realm, and I don't know much about some loose cultivation, after all, I am just a small person, and I can only know so much. ”

"Well, it's quite honest!" Dugu Yu was secretly shocked in his heart, and at the same time he also had an understanding of Deacon Zhu's viciousness. But he didn't show any performance on his lips, just responded lightly, and at the same time thought about how to deal with himself next.

"Oh, by the way, before I was arrested, I heard that this Heavenly Star Mine was sealed by Qianyuan Academy with a large array because of some things, and it has become a prison now. The man said suddenly.

"Oh, what is the matter?" Dugu Yu asked with some curiosity, you must know that this celestial star stone is a rare refining material, adding this ore to the refining tool can increase the strength of the blade by three percent, and Qianyuan Academy will not give up such a large fortune no matter how rich it is.

The man said in a low voice: "I heard that there are students who have been missing in the late mining stage of Qianyuan Academy, and finally sent two emperor-level elders to investigate, but the last one disappeared in the mine, and the other one died soon after." Speaking of this, the man paused, and continued to say mysteriously: "I heard that someone saw the missing elder appear once covered in white hair, and then the body of the buried elder also disappeared. Some people say that they have offended the mysterious existence in the mine and have been refined into zombies by that one. Others say that the two elders were possessed by something unknown. In short, there are different opinions, and there are countless strange speculations, but in the end, the Qianyuan Academy blocked the news, and if you want to know more, I am afraid that you can only go to the bottom of the mining area. ”

The man shook his head after speaking, obviously curious, but he didn't want to lose his life in vain.

Seeing that Duguyu was silent, the man asked cautiously: "My lord, I have said everything I know, ...... you see?"

"Count your kid acquaintance, get out!" Dugu Yu is not a murderer, and besides, this person is cowardly and spares his life, forgive him and dare not play any tricks.

"Yes, it's my lord, I'll get out, I'll get out. With that, he hurried out.

Dugu Yu was silent in the cave, he didn't expect things to be so complicated, he could have studied quietly in the academy, but now he is imprisoned in this prison. As for whether he can get out of trouble, Duguyu is a little uncertain in his heart.

The location of the cave was not hidden in the first place, and now that it is exposed, there is no need to stay here anymore.

Duguyu cleaned up and simply smeared his face to make himself look older than his actual age.

"There are few hiding places on the outskirts of the mine, and most of them are occupied, and now there are only two options, one is to kill people and seize them, and the other is to enter the mine. ”

Dugu Yu is a little embarrassed, if he enters the cave, with his strength, he is afraid that he will not even be able to leave the bones after being eaten, and now he can only see if he can find a cave with no one in the world, but it is really not good, then he can only rob it.

These days, he clearly understood that the weak eat the strong in the cultivation world, whoever is strong will be able to speak, otherwise, no matter how strong the power behind you is, there will always be people who will take risks.

After carefully searching for half a day, Duguyu found a total of four hiding places, but all of them were occupied by people. For today's plan, I'm afraid that the only way to do it is to rob it.

He appeared in one of the best hiding places, touched the mechanism in front of the door, and waited in silence.

"Who dares to break into my cave?" a rough voice came out, and then a man walked out.

The two looked at each other, both stunned.

"It's you!"

"It's you!"

"Hehe, boy, there is a way in heaven that you don't go, there is no door in hell for you to break in, your bald grandfather hasn't gone to look for you yet, you have sent it to the door yourself. The bald head bared his teeth and said with a grin.

"Long-winded!"

Dugu Yu split the ground and cut out directly.

"Huh?" The bald head was a little unconcerned before, after all, it had only been a few days, and he expected that Duguyu would not make much progress.

When the sword light met his approach, the bald head's face suddenly changed drastically, and he hurriedly drew his knife to block it.

With a "click", the Xuan-rank peak spirit knife became a fragment.

"No!"

The sound stopped abruptly, and the bald head had been split into pieces.

Dugu Yu looked at the mess and pouted, "Fight and fight, what so much nonsense, alas!"

Shaking his head and sighing, Dugu Yu picked up the bald storage ring on the ground, swept his spiritual sense, and found a strange thing.
