In the oncoming wind, there is a faint fluctuation of vitality, which is very regular.

"The wind here is not purely natural. Bai Yuelu also sensed the unique aura of this magic circle.

"How are your injuries?" Lin Yi happened to see the two female swordsmen who had been snatched by him before, breathing on the side, and the true yuan aura in the bodies of the two female swordsmen fluctuated, and they were obviously not lightly injured.

These two female swordsmen are twins, one is called the blue-clothed moth, and the other is called the blue-clothed butterfly, the two of them were originally very grateful to Lin Yi for his grace of not killing on the battlefield, at this time, hearing Lin Yi's question, both of them were a little flattered, and after a moment of stiffness, the blue-clothed moth saluted and said: "The injury is not too serious, but General Lin, if you go over, you should also be careful, the further you go on this road, the more amazing the wind is, and some of the winds in the wind are condensed into a bundle by the power of the magic circle, like an invisible flying sword." ”

"It's like an invisible flying sword?" Lin Yi was slightly stunned.

The two female swordsmen both nodded, changed to blue-clothed butterflies to speak, and said, "We just rushed forward dozens of steps before we were injured by this wind sword. ”

"It's the Sword Stream. Bai Yuelu's voice suddenly sounded.

"Sword Stream?"

Everyone's eyes were immediately focused on her.

"This is the unique formation of the Hidden Sword Mountain Sect of the Northern Wei Dynasty, but the Hidden Sword Mountain Sect was destroyed before the Northern Wei Dynasty moved its capital, and this formation has long been lost. Bai Yuelu calmly looked at the stone bridge-like passage and said, "This kind of magic circle must be built on the natural wind outlet, cut with a sharp sword and a magic circle, so that an invisible sword qi can be formed in the gangfeng, but it is only in an area of dozens of steps, and the power of the sword qi reaches its maximum." ””

Speaking of this, she glanced at the two female swordsmen and said, "The location where you were injured should be the most powerful place close to this sword stream. ”

"So isn't it true that the closer you get to the other side, the stronger the sword qi becomes?" Xia Ba Ying suddenly understood.

Bai Yuelu nodded, "As long as you pass through the area of dozens of steps, the power will naturally weaken, this kind of magic circle is to use the wind to create the illusion that the more you move forward, the stronger the power, the original Hidden Flow Mountain Sect's sword flow path magic circle is from top to bottom, built on the mountain gate ladder mountain road, giving people a feeling that they can't climb the mountain at all." ”

The two female swordsmen were stunned, although they could hear it clearly, but they knew that even if the power of those sword qi would not increase endlessly, they also realized that they could not penetrate the area of dozens of steps.

"You follow me. ”

Lin Yi said this to Bai Yuelu and Xia Baying, he looked at the "Sword Stream" in front of him, and felt that the sword qi related to Zhenyuan should not be able to hurt himself.

"You don't have to follow up, you don't have to wait here with so many sergeants, you just have to pay attention to the exits in and out of the city. When he started to move, Lin Yi said to these high-ranking generals of the Xifeng clan.

These high-ranking generals of the Xifeng clan respected Lin Yi like a god, and if they dared not listen, they immediately passed orders one after another.

......

Just like looking across the river, just listening to the movements in those tunnels, the hundreds of people at the end of the Sword Stream Road already knew about Lin Yi's arrival.

This kind of terrain is a terrain that is truly untouchable, and as long as there are enough cultivators to block this one, thousands of troops will not be able to pass.

However, in the face of this legendary Southern Dynasty general, everyone on this side of the Kendo stream did not have the confidence to stop him.

Because Lin Yi was the one who could make the Northern Wei army across the river unable to enter the city with the strength of one person.

Because this underground palace has three apertures, it is easy to think that it is a main hall with two side halls connected from the outside, but in fact, there is only one main hall inside.

It's just that the picture inside this hall is something that no one can imagine.

Closest to the door, there is a sword pit with a radius of more than ten zhang.

In this sword pit, there are thousands of sharp swords of various colors inserted in various postures, even if the light in this hall is extremely dim, but the shining sword light on the blades of these long swords still gives people a dazzling feeling.

At the end of this sword pit near the inside, there is a culvert like a drainage ditch, and there is no water gushing out of the culvert, but the wind is harsh, and there is a wind flow from nowhere, rushing out of this dark ditch, rushing into the sword pit, and then being chopped into countless wind beams, impacting the edge of this sword pit.

At the edge of this sword pit, there were countless silver runes stretching towards the mountain path that looked like a bridge outside, and there were also many irregular dark cyan gems.

These strange dark cyan gems kept shining like the eyes of many devils blinking in the darkness.

In the array of this hall, it is even more unimaginably spectacular.

A crystal glacier extending from the top occupies almost half of the space of the main hall, and behind this glacier, separated by a pile of black rocks, is a hot spring that constantly emits hot gas.

The water of this hot spring is milky white, but the deep bottom of the water is a deep red like a flame, like magma churning in the depths.

Half glaciers, half hot springs, and half of the cold and the heat are strange in this hall, but that's not all.

The pile of black rocks in the middle looked like a small black island, but among the black rocks was a purple vine that climbed on the glacier.

The main branches of this purple vine are the thickness of an adult's waist, that is, the branches that branched out, some of which are the thickness of an adult's thigh.

The purple vines had no leaves, but many of the slender vines were covered with white bell-like buds.

The center of the bud is also strangely sparkling and fluorescent.

"Holy Master, how long will it take?"

Tuoba Xiongxin was under this giant vine at this time, he looked at a cultivator sitting cross-legged under the giant vine with a solemn face, and said, "That person has already come, with those people outside, at most he can only block his tea time." ”

The cultivator under the giant vine was wearing a black robe, bowing his head slightly, and his face was strangely shrouded in a layer of black mist, and he couldn't even see his facial features clearly.

At the moment when Tuoba Xiongxin asked, his body paused slightly, he didn't reply, but the purple giant vine behind him was beeping, and many openings were suddenly cracked on the vine skin, and white juice continued to flow out of the cracked mouth.

A wonderful fluctuation of vitality began to ripple in the cracks in the skin of these vines, and in the next moment, in each crack, there was a round object bulging outward, as if some seeds were about to burst out.

However, as the white juice slid down the round objects like a waterfall, even a chill welled up from the depths of Tuoba Xiongxin's pupils.

The cracks that squeezed out of these vine bark were all white skulls!
