Xie Yun also agreed with this opinion, he had a deep understanding of the unhappiness of not having vitality in the small universe, if there was abundant vitality in the small universe now, how could he be chased so embarrassed by a Gu master.

The vitality in the demon pill was so abundant, Xie Yun injected all the vitality into the small universe, and it took nearly two days for the small universe to finally be filled, and then, the small universe began to become unstable.

"Are you going to evolve again?" Xie Yun had an experience, so he didn't panic this time, he calmed down and patiently controlled everything.

After a collapse and explosion, the small universe is several times larger than the original. To Xie Yun's surprise, after the Yuan Qi in it was compressed and condensed again, it seemed to have undergone a qualitative change, turning into a more advanced energy than the Yuan Qi.

"Immortal Book, what's going on?" Xie Yun asked.

"This is True Qi," Xianshu replied, "Remember the True Qi Xuanfa I taught you, in order to break through to the Jindan stage and transform ordinary Yuan Qi into True Qi." ”

There was still a part of the vitality in the demon pill, and Xie Yun did not hesitate at the moment, all of it was injected into the small universe, and it was continuously condensed into true qi. Soon, there was also a part of the True Qi in the small universe.

"This exercise of yours is truly amazing. Xianshu couldn't help but sigh again, "Although you are only a cultivator in the foundation building period, you already have the strength of the Jindan period, plus your dark and dark vision, it is estimated that ordinary monks in the Jindan period are not your opponents, as for the monks in the foundation building period, then you can completely kill in seconds." ”

Xie Yun's mood couldn't help but improve, but he soon became a little depressed: "It's a pity that I finally had a spirit weapon flying sword, but it was broken by the giant python, and the Tiangang mirror is not easy to use, if only there was a treasure." ”

"Don't dream in vain," Xianshu striking, "In this era, things like treasures are hard to come by, and they are not so easy to obtain. However, for spiritual weapons, I can teach you how to sacrifice. ”

"Then you didn't say it earlier!" Xie Yun was very dissatisfied with the rhythm of Xianshu, which was always half a beat slower.

"You haven't condensed your true qi before, and you can't do it if you teach you. ”

"Okay, I'm pretty comfortable with this flying sword, so you can teach me how to refine it. ”

So Xianshu began to teach Xie Yun how to refine spiritual weapons, and when the teaching was completed, Xianshu suggested that Xie Yun use the black wind obtained from killing Yujiang into the sacrifice of the flying sword.

So Xie Yun took out the black flying sword full of cracks, controlled the flying sword to levitate in mid-air, and at the same time, his mind moved, and a ball of flame appeared in his hand. This flame is a samadhi true fire formed from the true qi in the small universe, and it is very suitable for sacrificing spiritual weapons.

Xie Yun pointed his finger, and the flame suddenly flew towards the flying sword, instantly turning into raging fire and enveloping the flying sword's body, and the flying sword seemed to show a hint of softening under the flames of the Samadhi True Fire.

"I'll teach you the Concentration Seal and hit it on the flying sword!" said the fairy book.

At that moment, Xie Yun followed the teachings of the immortal book, his hands kept changing, and several runes loomed in Xie Yun's hands. After the flying sword gradually softened, Xie Yun slammed the Gathering Divine Seal on the flying sword, and several runes were tightly branded into the flying sword.

With the continuous penetration of the Concentration Seal, Xie Yun only felt that his connection with the flying sword was getting closer and closer, as if the flying sword had become like his own arm, and he could flexibly control it at will. And the cracks on the body of the flying sword were gradually merging, and it didn't take long for there to be no cracks on the sword body, and it was as good as ever.

"The heat is just right, inject into the black wind!" Xianshu shouted.

Xie Yun hurriedly took out the black wind wheal from the treasure bag and smashed the black wind wheal into the flying sword. The black wind was suddenly sucked into it by the flying sword like a long absorption of water, and with the injection of the black wind, the flying sword that was already black seemed to become more and more black, and it seemed that even the surrounding light could be inhaled into it.

Xie Yun didn't dare to be careless, and continued to concentrate on the sacrifice, controlling the progress of the flying sword sacrifice.

After the black wind was completely integrated with the flying sword, Xie Yun retracted his mind, and the flying sword would be regarded as a successful sacrifice.

"Huh......" It was only at this time that Xie Yun, who was sweating profusely and had exhausted both his true qi and divine sense, let out a long breath and relaxed his body slightly, but his eyes were still firmly fixed on the flying sword in front of him that was still suspended in mid-air with its own strength after removing all external forces.

The flying sword is still pitch black, and there is a faint black gas on the blade of the sword, Xie Yun knows that at this time, the flying sword already has the special surname of Yujiang black gas, as long as it is injured by the flying sword, even if it is as strong as Yang Peng's **, it will be corroded by the black gas, and Xie Yun faintly has a feeling that the grade of this flying sword seems to have gone up a level.

Xianshu explained: "Originally, it was only a medium-grade spiritual weapon, but at this time, it has been sacrificed into a high-grade spiritual weapon, but unfortunately there are no good materials, otherwise with the Gathering Divine Seal I taught you, it can be sacrificed to the best spiritual weapon." ”

Xie Yun already felt very satisfied, he looked at the flying sword covered in black and said, "It's so ugly, I'll call you 'Black Wind' in the future." ”

"It's ugly, the earth is dead. "Immortal book evaluation.

Xie Yun put away the flying sword, "It's time to go out and see how they are doing." With that, Xie Yun got up, pushed open the door of the wild store and walked out.

Duanmu, Miaoyun, Xiao Ling'er, and the ghost head not far away all ran over together when they saw Xie Yun walking out.

Miaoyun hurriedly asked, "Brother Xie, how are you?"

Duanmu also opened his mouth and asked, "How is it, did you succeed in rushing through the level?"

Xie Yun smiled and nodded, he had already entered the middle stage of foundation building in one fell swoop at this time.

Duanmu stared at Xie Yun and looked at it carefully, and suddenly said, "How do I feel that you don't look the same as usual?"

With the enhancement of cultivation, Xie Yun's entire temperament has changed greatly, and he looks even more profound. Miaoyun stared at Xie Yun for a while, but her heart beat even harder.

Duanmu laughed and said: "Congratulations on the improvement of the little brother's strength, Lao Tzu is getting safer and safer now, hahahaha!"

As soon as Duanmu's words fell, a mocking voice came:

"Are you safe? You're really safe when you get the Yama Palace. ”

I saw a few figures approaching, and a middle-aged man said to a young man with a magic staff next to him: "Lord Lich, these ghosts are blocking the road leading to the outside of the mountain. ”

The man who spoke earlier was the man with the staff, and he had already reached the level of a lich, and he said proudly: "I know, the master of the village, you go back first, after a stick of incense, this road will be as smooth as before." Behind this young man were four people shrouded in black robes, Xie Yun and Duanmu both knew that these must be four Gu masters.

After the owner of the village left, the young man with the staff held his chin high and said to Duanmu: "Duanmu Tusi, you are really blessed with a great life, so many people have not been able to kill you." ”

Duanmu Tusi replied unceremoniously: "How old are you, is Gu Shentong so unruly, and a young junior dares to talk to me like this?"

The young man holding the staff suddenly had a gloomy face, he was one of the outstanding wizards of the younger generation of Gu Shendao, his strength was rare in the younger generation, but his rank was low, this would be mentioned by Duanmu about seniority, he was naturally unhappy in his heart, he smiled and said: "You are now mentioning seniority with me, but this thing can't save you, no matter what, your elder today is going to be killed by my junior." ”

Duanmu was too lazy to talk to him, and wanted to let Xiao Ling'er solve him directly. Xie Yun stopped Duanmu and said, "Now that my strength has increased greatly, it's just time for me to try my hand." ”

Duanmu was not very relieved, he whispered to Xie Yun: "Don't mess around if you're not sure, you are the cultivator of the foundation building period, that kid is already a lich, equivalent to your Jindan stage monk in Kyushu, if you die, no one can control that ghost head, what if it provokes my little ancestor to kill me?"

Xie Yun smiled and said, "Don't worry, I'm free to measure." After speaking, Xie Yun carried the ghost head, strode forward, and greeted the young man holding the staff.

The young man holding the staff saw Xie Yunshang and laughed: "You are the monk who protects Duanmu Tusi, but you are just a waste of the foundation building period, but do you think you can win me by fighting alone?"

"Who said they were going to fight you alone. Xie Yun replied.

The young man holding the staff smiled even more presumptuously: "If you don't want to fight alone, that's fine, if you have any helpers, just call them all." ”

Xie Yun shook his head and said, "You misunderstood what I meant, I mean, let you call the four Gu Masters behind you." ”

The young man with the staff laughed so hard that he couldn't breathe: "It's just you? ”

"Really?" Xie Yun said, his figure quickly moved forward, and with a wave of his big hand, a huge handprint appeared out of thin air and fanned towards the young man holding the staff.

As soon as the youth staff clicked, a blue light flashed out, colliding with the handprint, and suddenly made a loud sound, which shook Duanmu's ears in the distance.

Although the big black handprint was shattered by the blue light, the blue light also showed its original form, and it turned out to be a small cyan snake, and the little snake was also shocked by the black handprint at this moment, and it spit out a few mouthfuls of blood and lay straight on the ground and died.

"I don't think you're worthy. Xie Yun returned the original words.

The young man holding the staff was so angry that his face distorted, his mouth opened, and a cloud of fishy smoke suddenly shrouded Xie Yun.

Xie Yun could feel the poison hidden in the smoke, and he deliberately pinched his nose and said, "Others are farting with their butts, but you are farting with your mouth, and it stinks." After speaking, Xie Yun summoned the ghost head and said, "Give me his fart to eat." ”

The ghost head stared, and screamed in his mouth, what did this guy think of himself, and let himself eat fart, but it had no choice but to get into the smoke, and inhaled it, and all the smoke was sucked into the mouth, and then it was so stinky that its face was green. This poison has a strong corrosive surname on **, but the ghost head does not have **, so it can't cause harm to it.
