When Bai Suzhen heard Cheng Ling's call, she instantly burst out with powerful spiritual power, forcing the old man back a little, and then retreated towards the entrance of the cave.

The old man flicked his fingers repeatedly, and thunderbolts blasted towards her. Bai Suzhen flashed reluctantly, and as soon as she got into the passage, she quickly rushed towards the exit.

The old man sneered and said secretly: If you want to go, now is a good opportunity to kill it in one fell swoop, so I hurriedly chased after it.

Cheng Ling was waiting at the entrance of the passage, and when he saw Bai Suzhen rushing out, he hurriedly threw out the array flag in his hand, and in an instant, a transparent light shield rose at the entrance of the cave, sealing the passage.

The old man didn't know it, and as soon as he crashed into the formation, he felt like he had hit a transparent film, and he couldn't rush out. He was furious in his heart and scolded: "What a cunning woman, she actually set up a closed formation outside the cave!"

Bai Suzhen ignored it and asked Cheng Ling, "How about it, can you seal it?"

At this time, the old man was frantically inducing the power of thunder and lightning, bombarding the membrane at the entrance of the cave, and the formation also produced bursts of fluctuations.

Cheng Ling flicked his hands and said, "What kind of person is this, the strength is so strong, I want to maintain the formation, Sister Bai, help me stabilize it!"

Bai Suzhen hurriedly stepped forward and entered the physical strength true element into the formation. Cheng Ling freed his hand, and secretly said in his heart, if a trapped formation can't work, then add a defensive formation and a sealing formation, and see if you can rush out.

The array of pillars and flags in his hand kept playing, Bai Suzhen desperately entered the true yuan, and the old man also struggled to bombard the light mask, if he was sealed in the cave, God knows when he could get out.

Both sides have their own means, and they are desperate. Fortunately, there was no thunder and lightning power on the outside of the cave, and Bai Suzhen still insisted on it.

The array pillars and array flags in Cheng Ling's hands were also played out one by one, and the sealing formation was about to be completed.

The old man secretly snorted badly, and said loudly: "Slow down, we don't know each other, as long as you don't disturb the cultivation of the deity, let you leave safely!"

He could already feel that the outer formation was slowly sealing it. Cheng Ling and Bai Suzhen ignored it, and just buried their heads in stabilizing and arranging the formation.

After a stalemate for a quarter of an hour, Cheng Ling finally knocked down all the formation nodes, and for a while, the formation was completely stabilized. The energy of the old man's bombardment could only shake a little.

Cheng Ling breathed a long sigh of relief and said, "Sister Bai, you can revoke the True Yuan, just with his current attack, I'm afraid it will take several years to break through this formation." ”

Bai Suzhen also breathed a sigh of relief and said, "This old turtle's defense is too high, and it occupies the geographical advantage of Lei Lingzhu, so it almost folded in his hand. ”

Cheng Ling asked, "You say he's an old turtle, what does his body look like?"

"There is a huge cave at the end of this passage, when I entered, he stayed in the cave, and there was a thunder spirit bead floating in the air above his head, purple, it was a turtle, as if he was absorbing the power of thunder and lightning to cultivate. ”

"Well, I see, it should be the Purple Electric Turtle. This kind of turtle is a rare thunder race, and it is very close to the power of thunder and lightning by nature, and their defense is very high, is his cultivation similar to yours?"

"Yes, the cultivation is similar to us, but he has taken advantage of this land, and I have suffered too much. Bai Suzhen was very unhappy, and if she was outside, she might not lose to that turtle.

Cheng Ling smiled and said: "It's okay, he is now sealed in the cave by us, but this is not a long-term solution, I haven't woken up yet, I just sealed the exit of the passage, if he destroys the cave from other places, he can still get out." ”

"What then? Or just seal the outside world as well!"

"No, the mountain cliff here is very huge, and the power of the formation seal will be weakened, and if the sealing area is too large, the formation can't be arranged. Looking at his current appearance, he shouldn't understand the formation, and the formation on the edge of the island was not set up by him. ”

"Well, it seems that he really doesn't understand, otherwise he wouldn't be trapped by your formation!"

Cheng Ling smiled and said, "That's easy, seal him for a while, let's explore this cave, since he is not the one who set up the formation, there must be other people in the cave!"

Bai Suzhen said: "But we didn't find anything on the way in before!"

"Sister Bai, you forgot, there is a fork in the road here, but there is no fluctuation of thunder and lightning power on that fork in the road, let's go in and take a look!"

Bai Suzhen was stunned, and the two walked in from the fork in the road.

The passage in the fork was not large, barely enough for one person to walk, and it was so dark that they could only gather their eyes and grope their way forward.

After about a stick of incense, I saw some hazy light in front of me, but it was faintly fiery red.

The two of them continued to move forward, walking hundreds of steps further, only to see a small cavernous space in front of them. The space is circular, only a few dozen square meters, and the walls of the cave around it are brightened and darkened by the fiery red light, which looks very infiltrating!

In the innermost part of the circular space, there was a humanoid skeleton, and nothing else.

Cheng Ling approached the dry bones and took a look, only to understand why there was a red light. I saw that at the location of the pelvis of the dry bones, a red flame was slowly beating, and the surrounding of the dry bones seemed to be arranged with a layer of sealing formation, so that the flames could not escape from the dry bones.

Cheng Ling observed the shape of the flame, and saw that it had a circular core in the middle, surrounded by a circle of flames, and there were sparks floating around it, which was very beautiful. He was overjoyed, he couldn't imagine that this was the "Meteor Fire" of the Heavenly Fire in the Strange Fire of Heaven and Earth!

This is really if you want to fall asleep, someone will send a pillow, I was going to take time to learn alchemy, but there was a lack of fire, so I sent one in front of me, and it was a heavenly fire.

According to the records of those books on the golden pages, this meteor fire is ranked ninth among the heavenly fires, which is very rare, and it is only possible to be conceived when the stars in the sky fall on the continent and cause impact.

The dry bones here should have obtained this fire by chance and sealed in the dantian. Looking at this posture, the master of this dry bone is a formation master, and the formation on the edge of the island is likely to be set up by him.

But what happened to him to die here. Cheng Ling did not immediately crack the sealing formation next to the dry bones, but carefully observed the dry bones.

Bai Suzhen stood beside him, and when she saw his face happy, she asked, "Brother Ling, is this flame rare, why don't you refine it?"

Cheng Ling shook his head and said, "Don't worry, this flame is temporarily trapped by the sealing formation, if the formation is broken, the flame may escape." Looking at the dry bones again, the bones on the body were broken in many places, showing that he had suffered very serious injuries before he died. ”

Bai Suzhen looked at it carefully, and agreed: "Yes, looking at the appearance of that bone, there are indeed many small cracks. Hey, Brother Ling, look at it, his left hand is pressed under the skeleton, as if there is a storage ring!"

Cheng Ling's heart moved, and he was busy looking at it seriously. Sure enough, under the skeleton of the upper body, the skeleton of one hand was pressed, and a bronze ring on the hand was really not easy to find because it was similar to the color of the ground.

Bai Suzhen was about to reach out and move the skeleton and take off the ring. Cheng Ling stopped her and said, "Sister Bai, don't wait." I'll set up a simple sealing formation outside first, so that this meteor can escape!"

After speaking, he began to arrange the formation around the dry bones, and Bai Suzhen could only wait on the side.

After a while, the formation was arranged, and Cheng Ling gently picked up the skeleton with his hand, and took off the storage ring in the dry bone's hand.

As soon as the skeleton moved, the seal at the pelvis fell off, and the meteor fire instantly spread a scorching breath, and the spark disappeared in place.

Cheng Ling had already prepared and arranged a sealing formation around him, but he couldn't rush out. Bai Suzhen nodded secretly, fortunately, Cheng Ling had foresight, otherwise he would have been run away by this meteor!

As soon as Cheng Ling pointed out, he fixed the meteor fire, and he began to refine. As soon as he made contact, he felt a powerful blazing energy rushing towards him, and he was busy running exercises to resist, while also increasing the strength of the true yuan and suppressing the blazing heat of the meteor fire.

Bai Suzhen stood aside and protected the Dharma for him. I don't have any opinion on Cheng Ling taking away the ring and Meteor Fire, Cheng Ling will not swallow the items in the ring alone, and she will definitely give it to her if it is useful to herself, as for Meteor Fire, she doesn't need it.

The heat of the meteor fire was very strong, and Cheng Ling resisted very hard, but fortunately, his true yuan was very pure, and he insisted on it for a while.

After a quarter of an hour, he had refined a third, and in this way, the heat of the flame was controlled, and the speed of his refining was also accelerating.

Half an hour later, the meteor fire was completely refined by him. I saw that as soon as his palm moved, a star-like flame floated in the palm of his hand, and he didn't feel the slightest scorching heat.

However, he also knew that the temperature of the meteor fire was very high, and if he hadn't refined it, attacking the enemy with this flame, he would definitely be able to burn the monks of the Jindan stage into ashes in an instant.

He looked at the flame in his hand happily, and in this way, his means of fighting the enemy increased, and he also had a capable flame to learn alchemy in the future.

As for the Dan furnace, it was already grabbed in the auction, and several were also looted in the Dan shop in Fang City, and one of them was even higher quality than the one in the auction.

This trip to the island can be regarded as a great gain, not only has the formation been upgraded to the sixth grade, but the cultivation has also reached the middle stage of Jindan, and he has also obtained a meteor fire, plus a ring of dry bones, and I don't know what treasures are in the ring.

Bai Suzhen couldn't bear it anymore and asked, "Brother Ling, do you want to see if there are any treasures in the ring?"

Cheng Ling smiled, and his divine sense swept into the ring. I saw that the space in the ring was very large, and it was also a high-grade storage ring.

There are not many things in the space, a bunch of spirit stones, all of them are medium-grade, about tens of thousands, and there are some herbs and formation materials, which are suitable for their own use. Finally, there are three books.

He took out all three books and opened them one by one. The first book recorded some alchemy, and I felt as if I had seen it there, and the second book recorded the formations on the island, which were not set up by the owner of the dry bones.

The third book is a codex, which records in detail some of the experiences of the master, as well as how to use the demon beast Neidan to improve his cultivation.

It seems that the record in the codex, Cheng Ling suddenly remembered that the owner of this dry bone was the stall owner's father who sold alchemy books on Canglang Island back then!
