Ling Yunpo couldn't remember how long it had been since he had fought such a frustrating battle.

If Senior Sister An hadn't been here, he could have let go and done what he wanted, attacking instead of defending, retreating without hesitation... But Senior Sister An followed him everywhere, so he could only play the role of Ling Yunpo honestly, and he had to use swordsmanship and swordsmanship alone, and from time to time he would have to take a few non-fatal sword energy blows to show that he had tried his best.

An Zhisu had no doubts, but her face became paler. In order to escape the pursuit with her junior brother, she really tried her best.

The two men fought and retreated, retreated and fought, and no one knew where they were going.

After all, the environment here is really unfamiliar to the two of them, and with the Crazy Sword Immortal chasing them step by step, they really have no leisure to observe the environment and choose a route.

After running for an unknown distance, he found that he still hadn't reached the edge of the swamp. Ling Yunpo realized that the direction he had chosen in a panic must lead to the depths of the swamp.

An Zhisu suddenly staggered. Although it was only a slight movement, Ling Yunpo still noticed it keenly.

"Senior Sister, are you poisoned?" he asked quickly.

An Zhisu did not answer, but Ling Yunpo grabbed her wrist and quickly probed her spiritual sense into it. After hovering in the meridians for a while, he soon discovered that the true energy in An Zhisu's body was almost completely contaminated by the green miasma.

"Senior Sister! Why are you..." Ling Yunpo was panicked and subconsciously wanted to blame her, but he swallowed the words back when they came to his lips.

What’s going on, Lingyunpo, don’t you know what’s going on?

He cursed himself in his heart, and then started thinking at the fastest speed in his life.

If you just keep running around like a headless fly, you'll definitely not be able to escape.

The reason is very simple. Although the mad swordsman's mind is confused, his footwork is not slow at all. It is obviously some kind of mysterious step that he uses instinctively.

"A Jing." Ling Yunpo said in a deep voice, "Have you recorded and analyzed everything?"

Kunlun Mirror did not say anything, but simply played back for him all the scenes of the Crazy Swordsman's previous battles in great detail.

Qing Ping Sword explained in coordination with the screen:

"I don't know what this footwork is called, but it contains the theory of Zhouyi Bagua. Please listen to me and I will explain it in detail..."

"Get to the point!" Ling Yunpo interrupted it rudely.

This crazy swordsman is coming to kill you, why are you still telling me something in detail?

"Don't interrupt me!" Qing Ping Jian also rarely scolded him, "The principles of Zhou Yi are profound and extensive. If I don't explain it in detail, you won't understand it at all!"

Ling Yunpo was speechless, and he didn't know why Qingping Sword suddenly got so angry, so he could only say anxiously:

"Then speak faster, I'll try my best to understand!"

Qingping Jian snorted coldly and began to explain to him in a rapid succession.

I have to say that this theory is indeed difficult. If it is written down, it will be like gibberish, difficult to understand and does not sound like human language.

But after all, Luo Yan studied the art of formations in the Penglai Temple, and that thing is like mathematics... With a good foundation in mathematics, how difficult can cryptography be?

Before I finished learning, the Crazy Sword Immortal came over from a distance, saying sinisterly:

"Don't run away, a user of the Seven Killing Sword Technique, do you only dare to run away like a mouse?"

Ling Yunpo didn't waste any time talking to him and directly activated the Qingping Sword's Taoist method of enveloping the blue mountains with a green mist.

Although the first level of the Qingping Sword had almost no lethality, it was extremely useful against this kind of cross-level enemy. Even the Crazy Sword Immortal who had reached the Great Perfection of the Golden Core Realm could not develop his spiritual consciousness in this water fog.

The moment the fog reached him, the crazy swordsman shot the Xinjin Huaqi sword at Lingyunpo. However, Lingyunpo had already figured out his routine and style of fighting, so he didn't try to take the attack head-on. He just swung the Leizhi sword backwards, and then "became one with the Qingping sword" and fled the scene.

"Why is it me again!" Lei Li Sword screamed and was knocked away head-on by Xin Jin Hua Qi Sword, then turned back under the guidance of Ling Yunpo's consciousness.

The Xinjin Huaqi Sword was still trying to chase, but Lingyunpo was not nearby at all. It slashed around a few times but in vain.

When the Crazy Swordsman rushed out of the fog, Ling Yunpo had already run away carrying An Zhisu.

"Senior Sister, please hold on for a while." When they arrived at a deep water area, Ling Yun stepped on the flying sword and found that An Zhisu had fallen into a semi-comatose state.

He quickly fed her a few pills, then held her wrist, put his hands together, put his fingers together, and poured his inner energy into her meridians, trying to draw out An Zhisu's poisoned inner energy.

It must be said that although Senior Sister An's true energy was not as strong as his own, it was extremely flexible and agile, and she kept dodging the pull of his true energy in her meridians.

Ling Yunpo was still listening to Qingping Sword's explanation of Zhouyi, and he also had to distract himself to guide An Zhisu's internal energy. He was extremely busy.

"Run, run, run, where can you run to?" The voice of the Crazy Sword Immortal floated over from afar again, "Is the essence of the Seven Killing Sword Technique just to hide and run?"

Ling Yunpo ignored him and forcibly removed part of the toxins in An Zhisu's body. He also absorbed the theory of Qingping Sword and nodded and said:

"Yeah, I almost understand."

"Will it be useful then?" Qingping Jian asked leisurely.

"I don't know." Ling Yunpo sighed, "How can I know if I haven't tried it?"

"Then there will be an opportunity soon." Qingping Jian said meaningfully.

Ling Yun was stunned for a moment, then suddenly lifted An Zhisu up, stepped on the Bagua, and quickly recited:

"The five meridians are out of order, and the time is moving; the four and seven are out of order, and the extravagance is far away..."

He just flashed and appeared dozens of steps away in an instant.

The place where he and An Zhisu were originally standing was pierced by the afterimage of the Xinjin Huaqi Sword.

The Crazy Sword Immortal suddenly appeared and looked at Ling Yunpo who was performing mysterious footwork. His cloudy eyes, which were originally filled with bloodshot, gradually widened.

Then, his veins bulged, his teeth clenched, his hair and beard stood up, and he roared with rage:

"My Fenyun Bagua Step! My Fenyun Bagua Step! How dare you learn it secretly...you dirty and shameless little thief!!!"

After uttering a few angry curses, the Crazy Swordsman quickly stepped onto the water surface, taking more than ten steps in an instant. His body flashed and he quickly chased after Ling Yunpo, his speed even half a second faster than before.

Ling Yunpo looked back and was almost shocked to death, shouting:

"Qingping, what's next? Read it quickly!"

"Thunder and lightning are in Mao, Zhen is thunder; the sky abyss is in You, Dui is a marsh..." Qingping Sword recited quickly.

Ling Yunpo repeated the same move and his steps became faster, widening the distance between them again.

However, his speed was still inferior to that of the Crazy Swordsman. Firstly, he was not proficient enough, and secondly, his true energy was not as strong as the other party's.

Even though he tried his best, mobilized his true energy, and raced his mind, he saw that the mad swordsman was still shaking his body, closing the distance by zhang.

"You run away again!" As Ling Yunpo was gradually caught up by him, the Crazy Sword Immortal roared in anger, "Do you really think that you can escape from my grasp just by learning a few of my footwork? When I catch up with you, I will peel off your skin and pull out your tendons, sacrifice your flesh and blood to the sword, and imprison your soul in the sword, torturing you day and night..."

Before he could finish his words, he saw endless thick fog rising in the surroundings again. Not only was his vision blocked, but his spiritual sense was also completely restricted. How could he even see the slightest shadow of Ling Yunpo?

"Ahhhhhhhhhhh!" The desperate roar of the Mad Swordsman came from the thick fog.
