Lin Qing, Ye Chen, and Bai Yun'er rested in the Wind Thunder Sword Valley for the night, and the next morning, they continued to explore. They wanted to find the exit of the Wind Thunder Sword Valley, and they also wanted to see if there were any other adventures and opportunities here.

Wind Thunder Sword Valley is a very mysterious place, it is said to have been created by an ancient sword immortal, and it is full of all kinds of wind and thunder power and sword intent. The demonic beasts here are also all wind and thunder attributes, which are very powerful and ferocious. In addition to the Wind Thunder Demon Beast, there are some other dangers and opportunities here, such as the Wind Thunder Formation, the Wind Thunder Stone Tablet, the Wind Thunder Sword Shrine, and so on.

The Wind Thunder Demon Core in Lin Qing's hand was the biggest gain he had here, it was an extremely precious treasure that could be used to improve his cultivation and swordsmanship, as well as to refine magic weapons and talismans. Lin Qing planned to integrate the Wind Thunder Demon Core into his Qingyun Sword to make his Qingyun Sword Technique more powerful and agile.

Ye Chen and Bai Yun'er also gained a lot here, and they respectively realized some of the mysteries of the way of wind and thunder and the way of the sword from some wind and thunder stone tablets, which was of great help to their cultivation. They also scavenged some precious materials and elixirs from the corpses of some Wind and Thunder Demon Beasts, which could be used to refine elixirs and magic weapons.

The three of them walked in the Valley of the Wind and Thunder Sword for three days and three nights, but they never found an exit. They feel as if they are lost in a labyrinth, and every time they come to a fork in the road, countless branching routes appear that leave them with no choice. They tried to use the compass and the map to discern the direction, but to no avail, because the force of the wind and thunder here interfered with the compass and the markings on the map.

"Lin Qing, do you think we can still go out?" Bai Yun'er asked a little anxiously.

"Don't worry, we'll find our way out." Lin Qing comforted.

"But we've been walking for so long, and we don't see any hope." Ye Chen also said with some frustration.

"Maybe we need to think differently." Lin Qing's eyes suddenly lit up and said.

"A different way of thinking? What's the idea? Ye Chen and Bai Yun'er both asked curiously.

"Think about it, this Wind Thunder Sword Valley was created by an ancient sword immortal, so what was his purpose in creating this place?" Lin Qing asked.

"The purpose? Isn't it to train younger generations? Bai Yun'er guessed.

"If it's just to train the next generation, then why design this place as a labyrinth? Why should we not be able to find an exit? Lin Qing asked rhetorically.

"And what do you say for?" Ye Chen asked.

"I feel like this place could be a test." Lin Qing said.

"Test? What is the test? Ye Chen and Bai Yun'er were both a little confused.

"It tests our understanding and comprehension of the way of wind and thunder and the way of the sword." Lin Qing said, "Think about it, this is full of all kinds of wind and thunder power and sword intent, every fork in the road is a question, and every question has an answer. Only by finding the right answer can you get out of this maze. ”

"You mean...... Do we want to use our perception of the way of wind and thunder and the way of the sword to guide us out? Bai Yun'er asked in disbelief.

"Yes. I think this is the last level left by that ancient sword immortal. Lin Qing said with certainty, "Only by truly comprehending the essence of the way of wind and thunder and the way of the sword can you pass this test." ”

"That'...... So how do we do it? Ye Chen asked.

"We have to feel the power of wind and thunder and sword intent at every fork in the road, and then choose the most suitable route according to our understanding of the way of wind and thunder and the way of the sword." Lin Qing said, "I believe that as long as we persevere, we will always find a way out." ”

"Okay...... Then give it a try. Although Ye Chen and Bai Yun'er still didn't quite understand, they still decided to give it a try with Lin Qing.

So the three of them began to sense the power and sword intent of wind and thunder at each fork in the road according to the method Lin Qing said, and chose the most suitable route according to their understanding of the way of wind and thunder and the way of the sword. They found that whenever they chose the right route, they felt a warm current flowing through their bodies, and some novel and beautiful sights appeared ahead; And every time they choose the wrong route, they will feel a chill invade their bodies, and there will be some dangerous and terrifying situations ahead. They are constantly correcting their understanding of the way of wind and thunder and the way of the sword, and they are constantly improving their control of the power of wind and thunder and the sword intent.

In this way, after countless choices and tests, after countless setbacks and successes, after countless tempering and improvements, in the center of the Wind Thunder Sword Valley, after the collision of two rays of light, a huge and deep cave was left behind, and suddenly there was a burst of vibration and roar. A powerful and violent force of wind and thunder poured out from the cave, forming lightning and whirlwinds that struck the three of them.

"It's ...... What was that? Ye Chen asked in horror.

"It's ...... The heart of the Wind Thunder Sword Valley! Lin Qing said in surprise.

"The center of the Wind Thunder Sword Valley? What's there? Bai Yun'er asked curiously.

"There's ...... there. The relics of the Wind Thunder Sword Immortal! Lin Qing said excitedly.

"Wind Thunder Sword Immortal? You mean...... The ancient sword immortal who created this Sword Valley? Ye Chen asked in surprise.

"That's right! He is the Wind Thunder Sword Immortal! He is a legendary sword cultivator, he is good at the way of wind and thunder and the way of the sword, his swordsmanship is unmatched, his power of wind and thunder shakes the heavens and the earth, he has killed countless monsters and demons with the power of one person, he is a real hero! Lin Qing said excitedly.

"That'...... What's in his ruins? Bai Yun'er asked.

"I don't know. But I think there must be treasures and legacies left behind by him. Perhaps, and his Wind Thunder Sword! Lin Qing said.

"Wind Thunder Sword? You mean...... A Wind Thunder Sword that is more precious than the Wind Thunder Demon Core? Ye Chen asked.

"That's right! The Wind Thunder Sword is the sword of the Wind Thunder Sword Immortal, it is a supreme artifact, it contains all the essence and hard work of the Wind Thunder Sword Immortal, it can control all the power of wind and thunder between heaven and earth, it can cut all obstacles and enemies, it is an invincible sword! Lin Qing said.

"That'...... What are we waiting for? Go for it! Bai Yun'er said excitedly.

"Wait! It's not that easy to get into! Look! Lin Qing pointed to the mouth of the cave and said.

When the three of them looked up, they saw a huge and complex formation above the entrance of the cave, which was engraved with various symbols and patterns, exuding a golden light. The formation was constantly rotating, sometimes shrinking, sometimes expanding, sometimes absorbing and sometimes releasing the power of wind and thunder. There were also countless thunderbolts and whirlwinds surrounding the formation, forming a powerful and dangerous barrier.

"It's ...... A Wind and Thunder Formation! Lin Qing exclaimed.

"This formation looks so powerful! How do we get in? Ye Chen asked.

"We have to crack this formation to get in." Lin Qing said.

"Cracked? Will you? Bai Yun'er asked.

"I won't. But I want to try. Lin Qing said.

Just as Lin Qing was about to try to crack the Wind and Thunder Formation, there was a sudden loud bang, and a golden light rushed out of the cave, heading straight for the three of them.

"Be careful!" Lin Qing shouted, and hurriedly took out the Wind Thunder Demon Core and blocked it in front of himself, Ye Chen, and Bai Yun'er.

The golden light collided with the Wind Thunder Demon Core and sent out a deafening explosion that shook all three of them back a few steps and spat blood.

"It's ...... What is it? Lin Qing looked at the golden light in horror, only to see it hovering in the air and rushing towards them again.

"It's ...... Wind Thunder Sword! Bai Yun'er exclaimed.

"Wind Thunder Sword? You mean...... Wind Thunder Sword Immortal's Wind Thunder Sword? Ye Chen asked.

"That's right! This is the Wind Thunder Sword Immortal's Wind Thunder Sword! It is a spiritual sword, it can act autonomously, it can sense the will of its master, it can slash all enemies! Bai Yun'er said.

"That'...... Why is it attacking us? Ye Chen asked.

"Because...... It doesn't know us! It thinks we're invaders! It wants to protect the remains of its owner! Bai Yun'er said.

"That'...... What are we going to do? Ye Chen asked.

"We ...... Only desperate! Lin Qing said.

Just when the battle between the three of them and the Wind Thunder Sword was at a stalemate, suddenly a crisp voice came from the cave.

"Stop! How dare you, ignorant mortals, disturb the sleep of our Lord! ”

The three of them were startled, and when they looked up, they saw a woman wearing a white robe and holding a long sword standing above the mouth of the cave. She has long flowing hair, delicate eyebrows, skin like snow, and an elegant temperament, but her eyes are cold and murderous.

"Are you...... Who? Lin Qing asked.

"I am a disciple of the Wind Thunder Sword Immortal, the Jade Frost Fairy." The woman said.

"Disciple of the Wind Thunder Sword Immortal? Aren't you already dead? Bai Yun'er asked.

"Humph! I am dead, but my soul is not extinguished. My Lord has sealed my soul here to protect me, so that I can guard his relics. I have been sleeping here all these years, until you greedy mortals come here and alarm my lord's Wind and Thunder Sword. The Jade Frost Fairy said.

"I see...... Then why don't you let us in? We just want to see the relics of your Lord, and there is no malice. Lin Qing said.

"See? What do you think this is? This is the holy land of my lord, the highest realm of the path of wind and thunder, and the treasure land that countless immortal cultivators dream of. How do you mortals deserve to be there? You're just going to defile this place! The Jade Frost Fairy said.

"Defiled? How can we defile here? We are also immortal cultivators! Ye Chen said.

"Immortal cultivator? What kind of immortal cultivators are you? You are only using external objects to strengthen your own strength, and you do not understand the essence of the way of wind and thunder. You know only that you covet profit, but you do not know how to fear heaven and earth. You only fight and kill, and you do not know peaceful coexistence. You will only be selfish and do not know how to sacrifice. You are so different from my Lord! The Jade Frost Fairy said.

"Humph! You say it lightly! What's so great about your lord? Isn't he also a mortal? Didn't he also rely on the Wind Thunder Sword to become a sword immortal? Didn't he also die here in pursuit of a higher realm? Lin Qing retorted.

"You...... How dare you insult my lord! You're looking for death! The Jade Frost Fairy said angrily, and with a wave of the long sword in his hand, he slashed towards Lin Qing.

"Be careful!" Ye Chen and Bai Yun'er hurriedly stood in front of Lin Qing and fought with the Jade Frost Fairy.

"Lin Qing! Go and crack the formation! We dragged her down! Ye Chen shouted.

"Good!" Lin Qing nodded, and while the Jade Frost Fairy was distracted, he rushed towards the mouth of the cave.
