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

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

"How are you injured?" Lin Yi happened to see the two female sword masters who had been snatched by him before regulating their breathing. The true energy aura in the two female sword masters was fluctuating and they were obviously seriously injured.

The two female swordsmen are twins, one is called Blue-clothed Moth and the other is called Blue-clothed Butterfly. They were originally very grateful for Lin Yi's grace on the battlefield. When they heard Lin Yi's question, both of them were a little flattered. After a moment of stiffness, Blue-clothed Moth gave a bow and said, "The injury is not too serious, but General Lin, you must be careful if you go over. The more you move forward on this road, the more amazing the wind is. Moreover, some winds in the strong wind were condensed into a bunch of invisible flying swords."

"Like invisible flying swords?" Lin Yi was slightly stunned.

The two female swordsmen nodded, changed to blue butterfly and spoke, saying, "We just rushed forward for dozens of steps and were injured by the wind sword."

"It's Jianyuedao." Bai Yuelu's voice suddenly rang.

"Sword Flow?"

Everyone's eyes immediately focused on her.

"This is the unique formation of Yinjianshan Sect of the Northern Wei Dynasty. However, Yinjianshan Sect was destroyed before the Northern Wei Dynasty moved its capital. This formation has long been lost." Bai Yuelu calmly stared at the stone bridge-like passage and said: "This magic array must be built on the natural wind vent, cut with sharp swords and magic arrays to form invisible sword energy in the gale wind, but in a region of dozens of steps, the power of the sword energy reaches its maximum."

Speaking of this, she glanced at the two female sword masters and said, "The location where you were shocked should be close to the strongest point of the sword flow channel."

"So it is not that the closer you get to the other side, the stronger the sword energy is?" Xia Baying immediately understood.

Bai Yuelu nodded, "As long as you pass through the area of ​​dozens of steps, the power will naturally weaken. This magic array is to use the wind to create the illusion that the more you move forward, the stronger your power will be. At that time, the sword flow path of Yinliu Mountain Sect was built from top to bottom on the mountain gate stairs, giving people the feeling that they could not climb the mountain at all."

The two female swordsmen were stunned. Although they heard it clearly, they knew that even the power of those sword energy would not increase endlessly, they could not pass through the dozens of steps.

"You guys follow me."

Lin Yi said this to Bai Yuelu and Xia Baying. He looked at the "sword flow channel" in front of him, and felt that the sword energy related to true energy should not be able to hurt him.

"You don't have to follow in, nor do you have to wait here. You just need to pay attention to the city and the exits outside the city." When you started moving your steps, Lin Yi said to the senior generals of the Xifeng clan.

These high-level generals of the Xifeng clan respected Lin Yi like a god, and they dared not to refuse to listen. They immediately passed the orders.

...

Just like looking at each other across the river, just listening to the movements in the tunnel, hundreds of people at the end of the sword channel already knew Lin Yi's arrival.

This terrain is a real terrain that can only be opened by ten thousand men. As long as there are enough practitioners to block this end, even thousands of troops will not be able to get through.

However, facing this legendary general of the Southern Dynasty, everyone at Jiandaoliu had no confidence to stop him.

Because Lin Yi was the one who made the Northern Wei army across the river unable to enter the city with his own strength.

Because this underground palace has three tops, it is easy to look outside, so it is easy to feel that it is a main hall connected to two side halls. However, in fact, there is only one main hall inside.

However, the pictures in this hall are beyond imagination.

The closest to the door is a sword pit with a radius of more than ten feet.

In this sword pit, thousands of sharp swords of various colors were inserted in various postures. Even though the light in the hall was extremely dark, the sword light shining on the sword edges of these long swords still gave people a sense of glare.

The sword pit is close to the inner end, and there is a drain-like ditche. There is no water flowing out of the ditches, but the wind is harsh. There is a wind flow that comes from somewhere. It rushes out of this ditches, rushes into the sword pit, and then is chopped into countless wind beams, impacting the edge of this sword pit.

There are countless silver runes on the edge of this sword pit extending towards the bridge-like mountain road outside, and are also inlaid with many irregular dark blue gems.

These strange dark blue gems are constantly shining, just like the eyes of many devils blinking in the darkness.

There is an even more unimaginable spectacular scene in the formation of this hall.

A crystal glacier extending from the top almost takes up half of the space of the hall. Behind the glacier, a pile of black rocks is a hot spring that keeps radiating heat.

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

Half is a glacier, half is a hot spring, and half is a strange cold and heat account for half of the hall, but this is not all.

The pile of black rocks in the middle is like a black island, but among the black rocks, there is actually a purple vine climbing on a glacier.

The main branches of this purple vine are as thick as an adult's waist, and some of them are as thick as an adult's thigh.

The purple vine has no leaves, but many of the slender vines are covered with white bell-like buds.

The center of this bud is also strangely shining fluorescent.

"Holy Master, how long will it take?"

Tuoba Xiongxin was under the giant vine at this time. He looked at a practitioner sitting cross-legged under the giant vine with a serious look on his face and said, "That man has come over. With those outside, he can only stop his time at most."

The practitioner under the giant vine was wearing a black robe, with his head slightly lowered, and his face was strangely covered with a layer of black mist, so he couldn't even see his facial features clearly.

Just as Tuoba Xiongxin asked, his body paused slightly. He did not reply, but the purple giant vine behind him was beating, and many holes suddenly cracked on the vine skin, and white juice kept flowing out of the cracked mouth.

A wonderful fluctuation of vital energy began to ripple in the cracked holes on these vines. In the next moment, in each crack, a round object raised outward, as if some seeds were about to break out.

However, as the white juice slid off these round objects like a waterfall, even Tuoba Xiongxin's pupils surged with a bitter cold.
