This pass is wide on the outside and narrow on the inside, there are more than ten miles in the wide place, and there are two or three miles in the narrow place, except for the island in the central area, the other areas are all lakes, and the lake is surrounded by steep stone walls, and the stone walls are covered by spiritual energy barriers.

"Check the aura barrier for invisible gaps. Wu Dongfang said to the three of them.

"I'll come. "Seeking frost and raising the air, it reached a height of tens of meters and cast a weak water dragon vortex, and the swirling water column moved forward close to the stone wall.

The stone wall is covered by an aura barrier, the water column can't touch the stone wall, and there is no water droplet on the stone wall wherever it goes, this is the fastest way to find it, if a certain stone wall gets wet with water, it is an invisible gap in the aura barrier.

The swirling water column crushes the ice surface of the lake and brings with it many fish from the lake, mainly carp and crucian carp, but also catfish and large loaches.

Fei Xuan and Xin Tong followed the frost search for the stone wall from the periphery, Wu Dongfang ran his aura to the island in the lake, this island covers an area of dozens of acres, it is not small, there is a beach on the periphery, the beach is fluorescent, look down closely, it is a lot of silver-gray pearls.

There are a lot of tall plants on the island, spider webs can be seen on the trees, all kinds of insects can be seen under the trees, there is a wooden house in the middle of the island, there are three wooden houses, the construction is very crude, except for a huge and simple bed, there are no other living utensils in the room, there are a large number of round beads stacked in the corner of the room, these beads are of different sizes, the big one is the size of a hug, the small one is the size of a thumb, and the materials are also varied, there are jade, there are pearls, and there are some wood beads.

Folklore dragon snake and other animals have a soft spot for beads, which derived the legend of the double dragon playing with beads, the giant dragon spitting beads, etc., it seems that the legend is not groundless, the strange dragon called the pig dragon by Fei Xuan and others is likely to have a collection habit, these beads should be its collection, but these things are obviously not all found by itself, there are many wooden beads with red dye on them, it is likely that those foreign wizards brought in.

There is a joke called fooling ghosts, these foreign wizards are fooling the dragon, not all animals are as treacherous as the prince, most of the animals have no qualitative improvement in IQ after becoming essence, these foreign wizards are likely to use these broken things to give gifts to the monster dragon, in exchange for wood and pearls in the pass.

The reason for this judgment is because there are some silver pearls and spices in the Qiankun bags of those foreign wizards, and there are many sandalwood trees growing on the island, which are very rare in the north, and the four famous incense of Shen Tan Dragon Musk Deer are already very valuable in the Xia Dynasty.

There are also two kinds of small animals on the island, one is the red-spotted lizard, which is called a lizard because it runs on the ground, but they actually look more like geckos. There is also a small red mouse, which is more than ten centimeters long, not ugly, and not very afraid of people.

Apart from these two animals and several insects, there were no other animals on the island, and I didn't see any snakes on the island when I walked around.

Fei Xuan and the others were looking for a gap in the aura barrier at this time, and he couldn't intervene, so he came to the beach on the outskirts of the island and sat down, although the lake water was turbid but had no peculiar smell, in the current words, this water quality belongs to fertile water, suitable for fish growth, the water is too clear but does not grow fish.

There is no sense of horror in the whole pass, if the surrounding stone walls are removed, the lake water is a little clearer, and you can come here for a vacation.

Half an hour later, the three of them returned and shook their heads at Wu Dongfang.

"I'll look for it later. Wu Dongfang took out the water altar and handed it to Fei Xuan, Fei Xuan waved his hand and didn't answer, after having the Qiankun bag, the three of them could already carry their own food and water.

"I'll go underwater and see. Frost turned and walked towards the lake.

Wu Dongfang did not stop Xunshuang from entering the water, the strange dragon that originally lived here had died, and there was no danger underwater.

Ten minutes later, the lake swelled sharply, the beach was flooded, and the three quickly retreated.

The water in the east area of the lake quickly rushed to both sides, and as the lake water separated, a stone path appeared at the bottom of the lake.

The three of them lifted their breath and flew by, landed around Xunhuang, looked down at the stone road under their feet, the lake separated and took away the silt on the stone road, and it can be clearly seen that this stone road is composed of square bluestone five feet square, leading straight to the east side of the cliff.

Wu Dongfang breathed out of the spring, extended the aura to explore downward, and found that the bluestone paved with the stone road was several zhang thick, "This stone road should be able to protrude from the water surface, go back, and find the source of the stone road, which is where the organ is located." ”

Xunshuang led the way in front, the three followed behind, and the stone road turned north for a few miles, which was a ninety degree angle, and after a few minutes, the four people came to the end of the stone road, not elsewhere, but the inside of the stone gate.

The four of them jumped out of the water and searched carefully from the stone walls on the left and right, but they didn't find the mechanism, only found a small hole, the thickness of a rolling pin for making dumplings, located on the stone wall on the right side of the stone gate, and the outside was also covered by an aura barrier.

Xin Tong drew flames from his palm, illuminating the inner peeping, "This is a small mechanism with at least five tenons inside. ”

"It's a lock, we don't have a key. Wu Dongfang said with a smile.

The three of them looked at him suspiciously, at this time, there was no word lock and key, and they couldn't understand what Wu Dongfang was saying.

"Brother Wu, what now?" Xin Tong looked up at Wu Dongfang.

"If you don't open the mechanism, you can't open the stone door, wait, wait for the prince to help us open the door." Wu Dongfang smiled helplessly, insisting on his original idea of catching a few indigenous wizards to lead the way, if you want to blame, you can only blame yourself for being soft-hearted, the prince's sentence 'They led those wizards over not to kill you, but to kill those foreign wizards with your hands' made him dispel the idea of capturing the indigenous wizards to lead the way.

"Is there any other way to think of it after half a month?" asked Xunshuang.

Wu Dongfang frowned and thought about it, and after a while, he remembered something, and found the golden inner pill from the Qiankun bag, the owner of this inner pill can break through the barrier here, enter and exit the pass at will, and theoretically pass through the aura barrier with this inner pill.

Hold Neidan with his left hand, touch the stone wall with his right hand, and sure enough, he touched the stone wall through the barrier.

The three of them were overjoyed when they saw this, and they all concocted the same method, and they all had this effect.

"Shatter the stone gate and go out to get someone to lead the way. Xunshuang said.

Wu Dongfang is already familiar with Xunshuang's style of doing things, this guy is just doing what he says, and when he heard this, he hurriedly stopped him, "Wait, wait, wait." ”

Xunshuang frowned suspiciously, and Wu Dongfang explained, "We don't know what impact the destruction of the stone gate will have on the entire Nine Palaces pattern. ”

"There's no other way but to break in. Xunshuang said, it has been almost half a month since she entered the mountain, and she is still staying on the periphery of Lingshan, she is a little anxious.

"It's too risky to break through the door, you can consider passing through the wall," Wu Dongfang raised his hand and pointed eastward, "There must be a stone gate under the cliff in the east, the stone gate must not be too thick, we can break the stone gate and enter the next pass." ”

"That will also affect the number of Nine Palaces Qi. Fei Xuan said on the side.

"There's no way about the impact, the meat is still in the pot if it's stewed, just don't spill it outside. Wu Dongfang made a final decision, "It's decided, it's better to smash the wall than to tear down the house, go through the wall, and I'll make up the stone door after I go in." ”

"Okay, that's the only way, but I don't know if destroying the stone gate in the pass will cause the breath to be chaotic. Fei Xuan said.

"Leave him alone. Wu Dongfang stored Neidan close to him, he found the root of the problem, during this time, out of politeness, he always asked Fei Xuan's opinion, and this guy has a bad problem that must be considered in every detail, following Fei Xuan's train of thought, always looking forward and backward, and making it very unsmooth.

"The next pass is the Kun Palace, and the ones stationed in it are native demons. Fei Xuan reminded.

Wu Dongfang nodded, lifted his breath and swept eastward, he remembered the location of the underwater stone road, came to the east side of the stone wall, and quickly found a stone wall suspected of being a stone gate, this suspected stone wall is smaller than the stone gate outside, with a diameter of about three meters, no door post was found, it may be telescopic, and a round hole was also found on the left side of the stone wall.

Wu Dongfang compared the approximate location, probed through the aura barrier, extended the aura to test the thickness of the stone wall, and found that the stone wall was eighty centimeters thick, and the ordinary mountain stone wall must be thicker than this, needless to say, this location is the stone gate.

After trying out the thickness of the stone gate, Wu Dongfang tried to change the shape of the gate with aura, and found that this stone gate was covered by the aura barrier all year round, and it was contaminated with a little aura contained in the aura barrier, which was not controlled by the aura of ordinary earth.

There is a problem with wearing the golden inner pill to pass through the barrier, you have to pass through the body first, if the aura goes first, it will still be blocked, but the palm of the hand close to the stone wall will affect the condensation and explosion of the aura, and the aura is different from the inch strength in martial arts, and there needs to be a distance to exhale.

At present, there are two options, one is to use the aura to slowly destroy the stone gate, and the other option is to use the sunset bow, he used ordinary arrows to shoot at the stone wall, which cannot pass through the aura barrier, and the meteorite arrow has a stronger ability to break the qi, and may be able to penetrate the aura barrier.

Instead of hammering around, it's better to shoot it.

Having made up his mind, Wu Dongfang took off the sunset bow and drew a meteorite arrow.

"The Sunset Bow makes a loud noise, and if it can't be broken in one fell swoop, the youkai in the pass will be alert. Fei Xuan said.

"I'll come. "Frost hunting raised the Xuanbing halberd.

"You use the Xuanbing halberd as a hammer. "Wu Dongfang opened the frost hunt, the frost hunting is only too early to cultivate, and if he wants to pass through the aura barrier and destroy the stone wall that is eighty centimeters thick, it is estimated that he will have to poke most of the night.

"Be cautious. Fei Xuan said.

"Get out of the way. Wu Dongfang retreated in the air, and the three of them hurriedly avoided it.

Retreating dozens of meters, Wu Dongfang stopped, inhaled deeply, bent his bow to gather momentum, and waited until the meteorite iron arrow was filled with aura, and suddenly let go, accompanied by a loud noise, a huge gap appeared in the stone wall.

As soon as the stone wall broke, Wu Dongfang vaguely saw a behemoth with yellow hair screaming and flying upside down, this unlucky guy was probably lying on the stone door to listen to the movement, and was shocked by the meteoric iron arrows filled with spiritual energy.

Wu Dongfang volleyed out, grabbed the arrow, and accelerated to rush forward, this was a once-in-a-lifetime opportunity to defeat the enemy.

Seeing that he was about to rush through the gap, he suddenly felt that his hands were grabbed, and before he could react, he had already taken Xunshuang and Xin Tong through the gap and entered the Kun Palace.

"Leave me one. Fei Xuan shouted from behind.

Wu Dongfang hurriedly turned around, only to see Fei Xuan standing outside the gap and hesitating.

"Come on in. Wu Dongfang shouted.

While he was shouting, Xunshuang and Xin Tong had already rushed east.

"Men and women need to enter at the same time. Fei Xuan was extremely anxious.

"I've brought both of them in, you're fine, come on. Wu Dongfang anxiously urged.

Fei Xuan hesitated slightly, bowed in, and suddenly disappeared the moment he passed through the gap.

"Huh?" Wu Dongfang was shocked.

"It's a giant rat, not a monster," Xunshuang turned around, "Where did Fei Xuan go?"

"God knows ......"
