After stepping into the foundation building, his six senses were extremely keen, even surpassing the ordinary late foundation building monks, and he had a special sense of danger that was almost intuitive.

"What's going on?" Lin Yuanfan became cautious, his divine sense was all released, and his eyes were firmly fixed on the surroundings.

Heaven and earth were silent, like a calm lake, there were no waves, he couldn't notice any changes, there was not a single demon beast around, let alone anyone, and the magic weapon in the storage bag that felt the detection of divine consciousness did not send out an alarm, it was unlikely that the monk was snooping in the dark.

Xuanniao continued to fly, that feeling still haunted his heart, there must be a demon when something goes wrong, there must be some unusual factor.

After thinking about the process of what happened, Lin Yuanfan had a guess and controlled the Xuanniao to fly down, and soon that feeling basically disappeared.

"And so it was. Lin Yuanfan's spirit was shocked, he looked up at the gray sky, and said to Xuanniao: "Go up." ”

Xuanniao flapped its wings upward, and as the height increased, that feeling reappeared, and the more Lin Yuanfan went up, the stronger the feeling became, and then even Xuanniao noticed the abnormality, and did not dare to fly up again, as if there was something terrible above.

Lin Yuanfan didn't force it, he left from the back of the Xuanniao and continued to go up, and came to a height that ordinary demon beasts would never come to, and the people of the two major sects definitely didn't have the courage to come to the sky, so naturally he couldn't find it, at this time he felt a huge pressure, and his divine sense could no longer explore upward, as if he had touched a thick wall.

His eyes froze, and a dense small prohibition appeared in his pupils, and his gaze became different, this was a simple pupil technique he cultivated, and he was able to see through many hidden supernatural prohibitions.

At this time, the sky in his eyes became different, and he saw a powerful barrier in the air not far above him that could not be detected by ordinary people's naked eyes, and this barrier spread far away in the sky, and the entire sky was covered by the barrier, like a cage covering all below.

"Is this the Great Void Locking Array?"

Lin Yuanfan was slightly shocked, he never thought that such a powerful sky-locking array would exist in the secret realm.

The Locking Array, as the name suggests, is a formation that can isolate an area, which is generally arranged by the Xiuzhen Sect as a mountain protection array, and the strength depends on the strength of the person who arranges it, and the Locking Array arranged by the Great Divine Power Monk can even surround a Xiuzhen star.

Although the air-locking array in front of him failed to reach that level, its coverage was not small, thousands of miles in a circle, almost the same as a country with a small area, this kind of air-locking array was definitely not something that ordinary monks could arrange, even the monks of the late Yuan Infant could not do this.

With a wave of Lin Yuanfan's hand, a sword qi slashed upward, and soon that sword qi hit the Locking Sky Array, and suddenly there was a fluctuation in the air, and the sword qi cast turned against him.

Avoiding the sword qi on one side of his body, Lin Yuanfan saw that there were other formations on this large array of locking the sky, which had functions such as detection, protection, and attack, and there was also an obscure aura hidden in the large array above that made him feel extremely dangerous.

"Who the hell set up this Great Empty Lock Array? Could it be Zong Huai's group of people? It seems that there is a stronger monk among them, otherwise it would be impossible for a few Yuan Infancy to arrange this Great Empty Lock Array. ”

Lin Yuanfan could only think of this, if those people arranged it, then it would make sense that there were no powerful demon beasts and other monks in the secret realm.

The Void Locking Great Array above was too powerful for Lin Yuanfan now, and it was impossible to open any gap with his existing means, even if he blew all the forbidden breaking cones he had refined.

Lin Yuanfan hurriedly wandered under the big empty lock array, silently thinking about something in his heart, since it was a big air lock array, there must be an array eye, and the center that controlled the formation must be in the array eye, if he could find the array eye, maybe he would be able to open the formation.

It may be extremely difficult for others to find an array eye in a thousand miles away, but Lin Yuanfan knows many formations, and he knows the composition of the Void Lock Array very clearly, and after half an hour, he deduced the location of the array eye according to the different prohibitions in various places of the Lock Void Array.

To his surprise, the calculated location of the array eye coincided with the location of the altar he was going to, and it was very likely that that altar was the location of the array eye of the entire Void Locking Great Array, the most core area of the secret realm.

Knowing the location, Lin Yuanfan didn't stay any longer, and returned to Xuanniao's back to continue his journey.

Xuanniao flew extremely fast, and the cultivation of the late stage of foundation building on his body shocked those demon beasts that were about to move, and the other demon beasts in the late stage of foundation building would not make a move easily, because they couldn't catch up with Xuanniao, and their shots were fruitless, so Lin Yuanfan spent nearly four hours finally coming to the periphery of that altar.

Standing high in the sky, Lin Yuanfan could only see that the area was shrouded in a white mist, and there was nothing to see inside.

The Xuanniao didn't dare to fly over again, telling Lin Yuanfan that it had obtained the magic crystal stone below, and if it went further, it would encounter the Spirit Devouring Bee and the Blood Devouring Vine.

The last time it came here was years ago, when it was attacked by a Soul Eater while it was getting the Dark Crystal, and was seriously injured, and if it hadn't escaped fast enough, it would have really died here, and it hasn't been here since, and there is a shadow in its heart.

Lin Yuanfan saw that there were multiple formations in the air in front of him, and it was impossible to pass through the air, so he fell from the air, and as for the Xuanniao, he took back the storage bag, and the ground was not a place where the Xuanniao was good at fighting, and it was not of much use outside.

Lin Yuanfan was very careful, slowly walked towards the mist, came to the edge, and saw that there were some fragments of ink crystals on the ground, and the formation on the ink crystals also disappeared, and there was a loophole.

As he was about to retrieve the fragments, there was a buzzing sound in the mist, and dozens of half-fist-sized Soul Eater Bees rushed out of the white mist, sharp stings about to stab him.

Lin Yuanfan jumped back, seeing that these Soul Devouring Bees were equivalent to the peak of the Grandmaster, and with one move, his own Soul Devouring Bees also appeared, and soon all the Soul Devourers that rushed out of the fog were killed.

"There's Spirit Devouring Peak here, isn't there even more. Lin Yuanfan smiled slightly, and he could collect some here to strengthen his strength.

After taking a look at the prohibition on the ink crystal, Lin Yuanfan was sure that it was just a simple isolation formation, and there was the same formation not far away, which should have been arranged in order to prevent the Spirit Devouring Bee from coming out, and now there was a gap in the formation, saving him a lot of means.
