In the depths of the Beyi Mountains, a castle looms, and most of its structure is made of genuine steel, except for the hard mixed iron rock, but from the outside, it gives people a sense of impregnability.

Not only does the castle look hard, but most importantly, it doesn't look bulky and is delicately decorated in many places. There were only a few weeds left in the nearly 100 zhang area of this castle, and it was empty as far as the eye could see, not alone, even if a hare ran around this area, it would be immediately seen by the guards above the castle.

"It seems that this ancient family is also very defensive, fortunately, the master will be invisible, otherwise it would be really difficult to get close to this castle......" Yun muttered, and then slowly disappeared his figure.

The cloud rushed towards the castle at an extremely fast speed, and came to the city wall in just an instant, standing behind a corner, looking at the guards patrolling the city wall, he didn't even dare to breathe.

After watching the patrol soldiers pass, Yun Cai jumped off the city wall with trepidation. At this time, the darkness has just dawned, and most of them are also asleep, except for the patrol soldiers who have taken over the shift, the castle is not very lively, in addition to marveling at the structure and size of this castle, Yun Shuang's eyes are quickly scanning the grass and trees in the castle.

"What is this place in front of this? there seems to be a spiritual wave turbulence of the enchantment......" Yun pointed to the right and whispered.

"From this floor plan...... It should be the place where the ancient family stored precious ores and weapons...... It should be the Sword Pavilion" Kui Ling was in the Jade Crystal Ring, holding the floor plan of the ancient family castle and studying it carefully.

"It seems that this pool of water should also be locked up in the Sword Pavilion......" Yun muttered, and then walked forward quickly.

"This Sword Pavilion is the core of the Gu family, it must not be so easy to enter, and now it is almost bright, you have ...... heart," Kui Ling instructed.

"Got it......"

Yun walked forward for about half a pillar of incense, and an extremely conspicuous large iron gate appeared in front of him, and in front of the right side of the iron gate, there was a stone tablet more than one person high, which was clearly engraved with the word 'Sword Pavilion'.

In addition, there is also a line of words 'Sword Pavilion Heavy Land, it is strictly forbidden to trespass'

"It seems that this sentence doesn't work for you......" Kui Ling said helplessly as he watched the clouds walk straight forward.

"This big iron gate...... It's too big......" Yun sighed as he looked at a large iron gate in front of him, which was almost three feet high.

"Master, there is no trace of a lock on this door, it is bare, it must be a mechanism......" Kui Ling said.

Seeing that the color is getting brighter and brighter, if you can't get in again, there will be more people for a while, and it will be really troublesome to go in again. The cloud began to look around for anomalies, trying to see if he could find the switch.

"Oops...... I was stunned......" Yun immediately slapped the door of his head, as if he suddenly realized, and then urged his spiritual power, under the observation of his eyes, the mechanism in the wall began to reveal little by little, and the cloud walked forward along the mechanism, and finally stopped on a stone statue in front of the iron gate.

Yun then smiled, and then slowly twisted the lantern in the stone statue's hand.

Click...... With a crisp sound, a crack opened in the iron door, and the cloud immediately slipped in.

As soon as Yun Yun took two steps inside, the big iron door behind him closed again. At this time, the clouds were completely shocked by the scene in front of them, and as far as the eye could see, there were weapons all around, all kinds of weapons, and it was magnificent to see the morning.

"These are just ordinary weapons, generally the more powerful weapons are on the display shelves in front, like the innermost secret room, there should be weapons with relatively high levels, or rare ores......" Kui Ling said.

Step forward, in the innermost part of this sword pavilion, there is a stone pillar with a diameter of about ten zhang, and these secret rooms are in this stone pillar, the stone pillar does not have any contact with the ground around it, the cloud came to this boundary and looked down, the bottom is bottomless, and there is a fire at the bottom, it should be the ground flame burning.

"On this stone pillar...... A few must have hundreds of secret rooms...... Can you tell where the water is?" asked Queiling, in amazement.

"It should be underground, if my guess is right, it should be the lowest layer of juice underground..."Yun poked his head out, looked at the cliff nearly a hundred zhang deep below, and muttered a little frightened.

"This Gu family is really good at finding a way...... I was still curious before, how strong the spiritual power must be to trap the invisible water spirit, but now I understand, it turned out to be with the help of the heat wave of this earth to weaken the spiritual power of the water spirit, so that even if the door is opened, I am afraid that this water spirit will not be able to escape......" Kui Ling said in shock.

Yun looked at the abyss below, entangled for a moment, and finally jumped into it, his body fell rapidly, and then Yun spread his thunder and lightning wings, feeling the oncoming heat wave, and this heat became more and more intense.

Fortunately, Yun has strong physical resistance now, otherwise he would have been baked to ashes a long time ago.

Yun sensed the strength of the enchantment, and finally came to the layer where the water spirit was imprisoned. At this time, he didn't have too many scruples, Yun pulled out the nine firmaments, slashed towards this enchantment, and easily opened a crack in this enchantment.

Yun stood on the steps that were more than a meter long, and he breathed a sigh of relief, and after the barrier broke, a cool feeling immediately came to his face.

"It seems that I have really found the right place, this water spirit is really locked up in this ......" Yun felt the cool feeling after the rain and walked in.

In this small secret room, there is a large pool with a diameter of three or four zhang in the center, the pool is about one zhang deep, and there is really a pool of clear water in it, as if it is about to boil, and it bubbles on the water surface.

Yun slowly stepped forward, and just as he was about to step forward to take a closer look, the originally calm and waveless water suddenly boiled, and then a wave of water rose, transformed into a human form, and swooped towards Yun, but at the moment when he was about to rush out of the pool, it seemed to be shaken back by an invisible force.

This sudden change startled Yun and subconsciously took a few steps back.

The human figure is still floating on the water, except for some can't see the real face, the whole appearance looks no different from the real person, and even looks at the graceful posture, more realistic like a bewitching girl.

Just as the cloud was at a loss, the figure slowly moved towards the cloud again.

"How...... This time, it was changed to a hairy man to intercede, it seems that your ancient family has no other way......" The human form formed by the water actually spoke, and the voice sounded like a woman dressed in a bewitching manner, and even Yun seemed to have imagined a scene in his mind, as if he had passed through such a place several times when he was in the city.
