These sword qi not only contain pure mana, but also have a good power of divine thoughts, so it is not easy to refine.

However, Li Muran happens to have the power of the Phantom, and the Phantom Divine Power has a unique feature in devouring the refining divine thought, which greatly increases Li Muran's refining speed.

Half an hour later, Li Muran sealed this sword qi in his body. Although he had not yet completely refined the sword qi in it into his true element, his aura and mana had also improved a lot.

More importantly, this is the divine thought and sword qi left by the high-level cultivator, which is extremely pure, which is of great benefit to the loosening of the bottleneck of Li Muran's exercises.

"Not bad, yes, after this incident, the junior disciple only needs to retreat for more than ten years and practice quietly, and he should be able to cultivate to the late stage of the Yuan Shen realm!" the old man of the Heavenly Sword nodded and said.

"Thank you, senior brother!" Li Muran put away the exercises and thanked him.

"You don't have to thank the old man, if you want to thank the master, this is the sword qi left by his old man!" said the old man of Heavenly Sword with a smile.

Li Muran nodded and bowed respectfully to Shitai and Bai Yujian.

At this time, the white jade sword also cut through the void, leaving a crack.

Everyone has sunk into the cracks, and Li Muran is no exception.

Afterwards, the crowd came to a larger stone hall. In the center of the stone hall is a sword array. The small sword with the handle of the array was inserted in the main hall. However, the spirit stones from the array were already running out of spiritual power, so this sword array was not in a state of activation.

"It seems that the test set by the master has ended, and the secret of his old man's disappearance is hidden in this formation!" Liu Chenfeng said with a move in his heart.

He and Hua Yuncong waited for the disciples, and took the initiative to take out those spirit stones that lacked spiritual power and replaced them with new high-grade spirit stones.

Immediately, Hua Yuncong re-energized the sword formation. Spiritual power was drawn from the high-grade spirit stones and gathered on those small swords in formation, so that each small sword inspired a series of fierce sword lights.

These sword lights intertwined with each other, gradually forming a light curtain of the size of a zhang.

Hua Yuncong said: "Master, this is a sword formation with spatial supernatural powers, which should be able to shuttle into a specific sealing space. However, if you want to shuttle in, you must use force to slash through this sword light curtain. ”

The old man of Heavenly Sword nodded: "I know, let the master cast a spell, and send you to go in one by one." ”

"Chenfeng, you come first!" the old man of the Heavenly Sword commanded Liu Chenfeng.

"Yes!" Liu Chenfeng immediately floated to the vicinity of the sword array.

"After entering, the teacher doesn't know what danger will happen, so you have to be careful! If you can find out the whereabouts of your and other ancestors, then it's best, if you can't, don't force it. The old man of the Heavenly Sword admonished.

"Disciple understands!" Liu Chenfeng nodded.

The old man of the Heavenly Sword said to the disciples again: "You and the master are as kind to the master as a mountain, so no matter what, the master wants to know whether his old man is safe and sound." However, you have not had direct contact with his old man, and if you don't want to take this risk, you won't be reluctant to be a teacher. ”

All the disciples said in unison: "The disciple is willing to go to find out the whereabouts of the master and fulfill the master's wish!"

The old man of the Heavenly Sword nodded, and then sacrificed his natal green sword, and slashed at the sword light curtain, and a sword light slashed out with a piercing sound of breaking the sky, tearing a crack in the sword light light curtain.

Liu Chenfeng immediately dodged and sank into the crack, and the crack immediately closed.

The glow of light in the sword array rose to the sky, and the light curtain of the sword array disappeared, and the spiritual power of those high-grade spirit stones embedded in the formation was also consumed at once.

"What a strong forbidden seal!" Li Muran was shocked, the stronger the space seal, the more energy needed to enter, this formation consumes a lot of spirit stones, and it can only be used once, and only one person can be teleported into the seal, which is enough to show that the space seal is very powerful.

Hua Yun took out another batch of high-grade spirit stones, and after replacing them, he activated the formation again.

"Sword Spirit, will you go too?" asked the Heavenly Sword Old Man to the Sword Spirit.

"Naturally, I want to see my master!" said the sword spirit, and with the help of the old man of the Heavenly Sword, he entered the sword formation and was teleported away.

The disciples of the Heavenly Sword Old Man all entered the sword formation one after another and were teleported to the mysterious space seal. The Old Man of Heavenly Sword gave an admonition to each disciple, looking very concerned.

In the end, only Li Muran and the old man of Heavenly Sword were left.

The old man of Heavenly Sword said: "Senior brother, although you are a disciple of the master, you have not really come into contact with the master, and you can't talk about the relationship between master and apprentice. You've already done my brother a lot of favors, and if it weren't for you, my brother wouldn't be here so far. ”

"For the rest of the road, you don't have to take any more risks. You might as well stay here and wait for me. The Old Man of Heavenly Sword said.

The old man of the Heavenly Sword is also very kind, just imagine that even a big man like Xuanguang Zhenren has inexplicably lost his traces and no longer appears in the Immortal Cultivation Realm, maybe the sealing space behind this teleportation sword array is extremely terrifying.

"I'm also interested in exploring it. Li Muran said: "Besides, I have received a lot of favors from my senior brother, and I have long stopped treating myself as an outsider!"

The old man of Heavenly Sword smiled slightly: "Senior brother doesn't treat you as an outsider either! Master likes talented rising stars the most, you are so talented and intelligent, if Master is alive, after he sees you, he will definitely be very important, and he will definitely accept you as a personal disciple!"

"Since you're going, Senior Brother naturally agrees. As he spoke, the old man of the Heavenly Sword motioned for Li Muran to stand beside the formation.

Immediately, the old man of the Heavenly Sword slashed out a sword again, helping Li Muran teleport away.

In the end, the Heavenly Sword Old Man personally replaced the spirit stone and prepared to enter it in person.

He slashed through the light curtain of the sword light with a sword, and then his figure disappeared into the crack in a flash.

Who knows, he actually sensed an extremely strong force of repulsion, which turned into a soft, but unstoppable breeze, forcing him out of the sword formation!

"What's going on?" The old man of the Heavenly Sword was shocked, he had teleported Li Muran and more than ten others away smoothly, but he couldn't shuttle through.

The Heavenly Sword Old Man tried again, he had obviously submerged in the crack of the sword array, but he was immediately forced back by the powerful force of repulsion!

With his strong strength, he couldn't compete with the power of repulsion!

"What a strong sealing power!" "The Heavenly Sword Old Man was shocked. He was no stranger to the power of this seal, it was a high-level spatial seal, and for those who had higher cultivation, the stronger the power of the seal.

"It seems that the mysterious sealing space behind this sword array does not allow monks of the Mahayana period to enter it. I don't know where the sacredness is capable of laying down such a powerful spatial prohibition. The Heavenly Sword Old Man muttered.

"However, Master was a late Mahayana monk before he disappeared, how did he enter this sealing space? Could it be that when he entered, the space seal was not strong, but after he entered, he strengthened the power of the space seal, so that the Mahayana monks could not enter? Why did he do this?" He had countless questions in his mind, but he couldn't find answers at this time.

"Now I can only wait here!I only hope that Chen Feng and the others can be smooth and safe, they are all monks who stand alone, even if the old man is not by their side, they should be able to take care of their own safety!"

......

Li Muran only felt that his eyes were dark, and there was a slight feeling of dizziness in his mind, and then he disappeared into the sword array.

The next moment, he naturally ran the "Taixu Sutra" exercises, and his divine thoughts suddenly became very sober, and the feeling of dizziness disappeared without a trace.

"Uncle Li is here too!" Liu Chenfeng's voice came from not far away.

He found that there were many people floating around, all of them were the disciples of the Heavenly Sword Old Man, but some of them were groggy, and some were even unconscious.

Liu Chenfeng was the first to come here, his cultivation was also the highest, and it was not surprising that he was the first to wake up, Li Muran was the latest to arrive, but he also came to his senses, which made Liu Chenfeng secretly praise Li Muran's strong thoughts.

"Uncle Li, help them come to their senses!" Liu Chenfeng said to Li Muran.

Li Muran nodded, and he, Liu Chenfeng and the others respectively injected a divine thought into the bodies of those disciples who were dazed or unconscious. This wisp of divine thought was like a wisp of cool spring water, flowing all over the disciples' bodies, and all the disciples quickly woke up one by one.

"Where is this? The power of the space seal here is so strong, we almost fell unconscious!" Liu Chenfeng said.

Everyone looked around, only to see the gray sky above, the pitch black and bottomless abyss below, and the chaotic wind coming from the abyss below.

"Let's wait for Master. The sword idiot said.

Everyone agreed with this mention, and no one moved, just waited quietly in the same place. Those disciples who were still a little drowsy, sat cross-legged in mid-air and used their divine thoughts, gradually eliminating their discomfort and becoming more sober.

I waited for half an hour, but there was no movement.

"What's the matter, why hasn't Master come yet?" Liu Chenfeng said in shock.

Li Muran was also confused, and all the disciples looked at each other, not knowing why.

"I know!" Hua Yuncong suddenly said, "The space seal here is too strong, so the master can't enter!"

"I can come in, why can't Master?" asked the sword idiot, puzzled.

"Because this kind of spatial seal is very special, I heard that there is a kind of spatial prohibition, and for those who have a higher cultivation, the stronger the prohibition. Master's cultivation is too high, so he can't use that teleportation sword array to enter here!" Hua Yuncong said.

Li Muran nodded: "Yes, I have also heard of this kind of prohibition below." However, to be able to keep the Mahayana monks out, the monks who laid down the prohibition of this space in the first place are definitely not trivial!"

"How should this be good?" Fang Tianao and the other disciples were suddenly quite worried, this was an unknown danger, they didn't know how to get out at all, if the master was not there, all the disciples were like dragons without a leader, and they had lost their greatest support.
