At night, in the grass on both sides of the stream, thousands of red-headed centipedes about three inches long appeared in a moment, and these guys were highly poisonous at a glance, stumbling in the grass, and after a while, even the trees were crawling, making people's scalp tingle.

Although Wei Wuxian was not afraid of these little poisonous insects, it was troublesome to be bitten by them, thinking that Xie Sanyi and the others should have encountered this group of poisonous centipedes, and drove the flying sword through the forest from the air.

Wei Wuxian took out a flying sword, turned over and stepped on it, and headed towards the eastern edgeworth.

He flew very slowly, checking all the way to see if there were any traces left by Xie Sanyi and others along the way, but unfortunately he still found nothing.

There were no straight roads in the mountains and forests, and the slightest deviation in the direction would be very far away, so Wei Wuxian had no choice but to dispel the idea of looking for them and prepare to go directly to Daegu County.

The mountain road is difficult to walk, so Wei Wuxian climbed above the woods, so that there was no need to detour, and he could go directly to his destination. After resting for a quarter of an hour before, he had recovered fifty percent of his Yuan Strength, and it was not a big problem to deal with ordinary fighting methods, and his courage was much stronger.

The snake pan mountain range is shaped like a coiled big snake, the head of the snake is located in the north of Yanzhou, the tail of the snake is in the depths of the mountain, and the continuous mountain range surrounds as many as nine layers.

Wei Wuxian is now approaching the vicinity of Snake Tail, where the terrain is much lower than the surrounding area, because it is surrounded by the nine-story mountain range outside, the temperature is in a state of humidity and heat all year round, and the obstacle is deep, which is the most favorite area for poisonous insects.

It is said that the Northern Barbarians once sent a powerful army of 10,000 people to attack Yanzhou from Shepan Mountain, but there was no news after the team entered, and it is still unknown whether it is alive or dead, so now the Northern Barbarians would rather pay a high price to attack the Jade Bottle Pass and Jialan Pass, and will not choose to take a shortcut and send people over the mountain range to attack the Great Xia Kingdom.

Wei Wuxian didn't want to take a long detour, so he found an obstacle avoidance pill and prepared to pass directly through this hundred-mile-wide area.

He was very cautious, controlling the height of the flying sword about twenty zhang above the ground, and the Gangfeng at this height was only one and a half levels, so there would not be much problem with the flying of the sword.

Gangfeng is a definition of the strength of the airflow by the monks, and the monks can withstand up to two levels of Gangfeng during the Qi refining period, which is about the strength of the airflow between 30 and 50 zhang above the ground. After the foundation is built, the bearing capacity can be increased to up to three levels of Gangfeng.

The topography of the Shepan Mountains is unique, surrounded by nine layers of mountains, the outer layer is higher than the other, and the air flow spirals inward, but because the area is too large, this change is generally not felt.

Of course, Wei Wuxian is not an ordinary person, and he has a very clear sense of the strength and weakness of the airflow and the direction of the flow, which is why he is so careful, not daring to get too high from the ground, for fear that the airflow in the center will suddenly speed up and cause him to react too late to have an accident.

Sure enough, as he approached the center of the snake's tail, the airflow gradually strengthened, and it could be clearly sensed that it was rapidly turning from left to right.

Wei Wuxian didn't dare to take any chances, and when he looked around, he found that there was a narrow bright light not far ahead, perhaps a stream, reflecting the light under the light of the stars and moon.

Wei Wuxian Edgeworth passed, and the closer he got to that place, the more frightened he became!

It was not a stream, but a long circular deep ditch, under which were scattered white bones, and on top of them were phosphorescent dots, which looked like a flowing stream.

This kind of place was not a good place at first glance, and he was about to turn around to avoid it, but suddenly he froze in place.

Somewhere in the pile of bones in the deep ditch protruded something, and a word was carved into it.

This word is very ancient, if Wei Wuxian was not born in the Yan Palace, but after the current royal family, he would never recognize the word on it.

Because this is the ancient word used by the heavens during the sacrifice of the Great Xia Dynasty.

If he's not mistaken, it's a 'royal' word.

Ancient characters actually appeared in this deep mountain field, which made Wei Wuxian immediately curious, and he slowly flew forward at the moment and landed on the edge of the deep ditch.

Now he saw it clearly, the ancient character was indeed the word 'royal', engraved on a stone tablet about a foot wide, so he took out a scimitar and pulled away the white bones scattered on the side of the stone tablet, revealing the part below.

【Imperial Weapon Sect Refining Fire Cave Secret Trespasser Dead】

This is actually a sect boundary monument!

The name of the 'Imperial Weapon Sect's Fire Refining Cave sounds like a sect that focuses on refining weapons, and this place should be the top secret location of the sect's refining magic weapons.

Wei Wuxian was a little excited in his heart, looking at the words on the boundary monument, he knew that the 'Imperial Weapon Sect' was an ancient sect, since the boundary monument was here, then the ruins of this ancient sect should be nearby.

He unleashed his divine sense again and searched forward along the deep ditch, hoping to find the location of the site of the 'Imperial Weapon Sect's Fire Refining Cave.

The deep gully is encircled by a solitary peak, and the terrain gradually decreases to the east, and the deep gully narrows and narrows, until it finally closes and breaks off at the edge of a rift.

Under the light of the stars and the moon, the water and vapor above the rift valley are thick, and the trees below are luxuriant, and the bottom is not visible. Needless to say, such a place is inhabited by a large number of poisonous insects and exotic beasts.

Wei Wuxian used his divine sense to inspect the mountain hidden by vines and thorns, and suddenly his eyes lit up, and there was a downward stone path thirty zhang away on its left.

Wei Wuxian shook his spirits, took out a scimitar, and walked towards the stone path. The stone path has not been walked for many years, and it is covered with thorns and vines on both sides, and it is not easy to descend from it.

However, this obviously couldn't stop Wei Wuxian's enthusiasm for treasure hunting, and with a scimitar in hand, he slowly walked down through the thorns all the way.

For safety, he arranged a layer of Yuangang hood around his body to prevent being bitten by poisonous insects.

The stone path was steep, with rusted chains on both sides, and it took Wei Wuxian an hour to reach the bottom of the valley.

He didn't rush forward, but took a Yuan Qi Pill to replenish the Yuan Power consumed.

After resting for half an hour under the stone path, he began to move on, and during this time, through his divine sense, he noticed that there was a hole made of bluestone in the cliff face not far ahead.

Wei Wuxian cleaned up the entrance of the cave, revealing the three ancient characters of 'Fire Refining Cave' on it, with a smile on his face, he casually cut three wooden sticks, found some small branches nearby and tied them to make torches, and then lit them and walked into the cave.

The passage is very long, from top to bottom is a row of stone steps two zhang wide, because there has been no one for too long, it has become a paradise for bats and snakes and insects, the torch in Wei Wuxian's hand alarmed a group of bats, and there was a rustling sound on the surrounding rock walls, many insects were lured out by the firelight, and some even flew towards the torches and Wei Wuxian.

Wei Wuxian had a layer of Yuangang Hood attached to his body, and those flying insects seemed to hit the wall and were bounced out.

The passage went down, and after walking for more than 30 feet, it came to the end. This place was different from the other underground passages, it was a bit stuffy, but there was still air flowing, and Wei Wuxian looked around with a torch and found a groove on the right side.

This groove is about a palm's width and an inch high, and there is a pull ring inside, which is supposed to be the mechanism that opens the secret passage.

Wei Wuxian cleaned up the impurities inside, and then grabbed the pull ring, the palm of his hand was actually a little hot, which made him hesitate slightly.

Because no one knows what will happen when they pull it apart!
