Hungover, I crossed over to the psychic realm

When the last boulder with flames turned into powder under the fierce resistance of Lin Yu and Li Qiang, the entire space seemed to heave a sigh of relief with the end of this arduous battle. The scorching air gradually cooled down, and thediffusedust and smoke slowly dissipated, leaving only the devastated ground and the two exhausted but determined people. Their clothes were tattered, stained with blood and dust. Every wound told the intensity of the battle just now.

The illusory figure of the old man emerged again. He nodded slightly, and a trace of imperceptible admiration flashed in his eyes. "You have already passed the test of strength. But the secret of the Spirit Pearl is far more than just strength. Next, is the challenge of wisdom." His voice echoed in the empty space, carrying an unquestionable majesty.

As soon as the words fell, the surrounding scenery changed again. The originally broken ground gradually became flat. A series of ancient scroll paintings emerged on the surrounding walls. The scroll paintings depicted mysterious formations, strange runes, and various postures of cultivators. And then, the old man threw out a series of complex and profound puzzles. These puzzles involved ancient formations, mysterious runes, and the deep mysteries of cultivation. Each puzzle was like an insurmountable mountain, standing in front of Lin Yu and Li Qiang.

Lin Yu and Li Qiang exchanged a glance and saw the same determination in each other's eyes. They knew very well that the upcoming challenge would be more difficult than the previous test of strength because it not only required them to have powerful strength but also keen thinking and profound knowledge reserves. They took a deep breath, calmed down, got rid of distracting thoughts, and relying on their years of cultivation experience and profound accumulation of knowledge, they began to concentrate on solving these puzzles.

The first puzzle was about an ancient formation. The old man's voice sounded in their ears: "This formation is called the 'Chaos Reverting to the Origin Formation'. The principle of its operation is related to the balance of yin and yang in heaven and earth. If you can figure out how to activate this formation, it will be the beginning of solving the problem." Lin Yu and Li Qiang stared at the complex formation pattern on the wall and fell into deep thought. Lin Yu's gaze slowly moved over the lines and nodes of the formation, trying to find the pattern from those seemingly chaotic patterns. Li Qiang slightly closed his eyes, mobilized the knowledge about formations in his mind, and tried hard to recall the similar formations he had seen before.

"I remember that in an ancient book, it was mentioned that the Chaos Reverting to the Origin Formation needs the power of yin and yang as a guide," Lin Yu suddenly spoke, breaking the silence. His voice was a bit hoarse due to fatigue, but there was a glimmer of excitement in his eyes.

Li Qiang opened his eyes and nodded: "That's right, but how to introduce the power of yin and yang into the formation is still a difficult problem." As he spoke, he walked to the wall and carefully observed the details of the formation.

The two began a heated discussion, exchanging their ideas. Their voices echoed in the empty space, sometimes passionate, sometimes low. In the continuous discussion, they gradually found some clues. Lin Yu discovered that some nodes in the formation had a subtle connection with the positions of the yin-yang and the Eight Trigrams. He excitedly pointed at those nodes and explained his discovery to Li Qiang.

"Look, the positions of these nodes exactly correspond to the positions of Qian, Kun, Zhen, Xun, etc. in the Eight Trigrams. Maybe we can introduce the power of yin and yang in the order of the Eight Trigrams," Lin Yu said.

Li Qiang thought for a moment and then said: "It makes sense, but the intensity and timing of the power of yin and yang are also crucial. If there is the slightest mistake, not only will we not be able to activate the formation, but it may also trigger a backlash."

After some careful consideration, they decided to first try to simulate their own spiritual power as the power of yin and yang according to the order of the Eight Trigrams and slowly inject it into the nodes of the formation. Lin Yu mobilized the yang attribute spiritual power in his body, and Li Qiang mobilized the yin attribute spiritual power. The two carefully injected the spiritual power into the corresponding nodes. As the spiritual power was injected, the formation began to tremble slightly and emit a faint light.

"We've succeeded!" Lin Yu exclaimed excitedly. But before they could be happy for too long, the formation suddenly shone brightly, and a powerful force surged out from the formation, knocking the two of them flying.

Lin Yu and Li Qiang fell heavily to the ground, and a trace of blood oozed from the corners of their mouths. They struggled to get up and looked at the still shining formation, their hearts filled with confusion.

"It seems that we only found part of the answer," Li Qiang wiped the blood from the corner of his mouth and said.

They fell into deep thought again, carefully recalling the previous process, trying to find out where the problem was. After some thinking, Lin Yu suddenly thought of a key detail.

"We only considered the injection order of the power of yin and yang just now, but we ignored the integration of the spiritual power. The key of the Chaos Reverting to the Origin Formation lies in'reverting to the origin'. Maybe we need to integrate the power of yin and yang in the formation to truly activate it," Lin Yu said.

Li Qiang's eyes lit up: "You're right! Let's try again."

This time, while injecting the spiritual power, they used special spiritual power operation techniques to make the power of yin and yang integrate with each other in the formation. As the power of yin and yang integrated, the formation emitted light again. This time, the light was more stable and brighter. Finally, the formation was successfully activated, and a ray of light shot up into the sky, illuminating the entire space.

With the solution of the first puzzle, the light in the space became a little brighter, and the Spirit Pearl seemed to be a step closer to them, as if encouraging them to move forward. Lin Yu and Li Qiang were filled with a sense of accomplishment, and at the same time, they were more determined to continue solving the puzzles.

And then, the old man threw out the second puzzle. This time, it was about the interpretation of the mysterious runes. The old man said: "These runes contain ancient wisdom and power. If you can interpret their meanings, you can find the key to the next stage."

A row of strange runes emerged on the wall. These runes were twisted and winding, exuding a mysterious aura. Lin Yu and Li Qiang walked to the wall and carefully observed these runes. They found that these runes were somewhat similar to those they had encountered in the swamp before, but they were more complex.

Li Qiang took out an ancient book that he carried with him. This ancient book recorded various rune materials he had collected over the years. He began to compare with the ancient book, trying to find out the meanings of these runes. Lin Yu closed his eyes and used his spiritual power to try to resonate with these runes.

After a long time of hard work, they gradually interpreted the meanings of some runes. These runes seemed to be telling an ancient story about a mysterious cultivator and the powerful power he mastered. As the interpretation deepened, they found that there was a certain logical relationship between these runes. Through this relationship, they could infer the meanings of more runes.

"I think I know the secret of these runes," Lin Yu suddenly opened his eyes and said. "These runes are the record of a cultivation technique, and this technique has a close connection with the powers we encountered before."

Li Qiang looked at Lin Yu in surprise: "Really? Then let's take a look quickly. Does this technique help us solve the next puzzle?"

They continued to interpret the runes. With the in-depth understanding of the cultivation technique, they found that some cultivation techniques and methods in the technique could just be used to solve the current puzzle. According to the method recorded in the cultivation technique, they used special spiritual power fluctuations to communicate with the runes on the wall.

Sure enough, as they communicated, the runes began to change and gradually combined into a new pattern. This pattern was in the shape of a key. With the appearance of the key pattern, a mysterious door appeared in the space.

"It seems that we've succeeded," Li Qiang said excitedly. They walked to the door, took a deep

breath, and then slowly pushed the door open.

Behind the door was a huge room. In the center of the room, there was a huge crystal ball. The crystal ball emitted a soft light, and the light seemed to contain endless knowledge and wisdom. The old man's voice sounded again: "This is the last puzzle. The crystal ball contains the deep mysteries of cultivation. If you can understand the true meaning from it, you will have passed the challenge of wisdom."

Lin Yu and Li Qiang walked to the crystal ball, stared at the flickering light in the crystal ball, and fell into deep thought. They felt that there was a powerful spiritual force contained in the crystal ball, and this force seemed to be guiding them to explore the deeper levels of cultivation.

Lin Yu closed his eyes and slowly integrated his spiritual power into the crystal ball. In the world of spiritual power, he saw the figures of countless cultivators. They were cultivating in different scenes. Some were meditating in a cave, some were cultivating under a waterfall, and some were comprehending under the stars. The cultivation methods and techniques of these cultivators were different, but they were all pursuing the same goal - breaking through themselves and reaching a higher realm.

Li Qiang also integrated his spiritual power into the crystal ball. He saw the different stages of cultivation, from the initial introduction of qi into the body, to the later condensation and application of spiritual power, and then to the final breakthrough of the realm. Each stage was full of challenges and opportunities. He also saw the perseverance and courage of the cultivators when facing difficulties and setbacks, which deeply inspired him.

Under the guidance of the crystal ball, Lin Yu and Li Qiang began to think deeply about the deep mysteries of cultivation. They recalled their own cultivation experiences over the years. Those difficulties and setbacks they had encountered, and the joy and comprehension after successfully breaking through all came to their minds at this moment. They gradually realized that cultivation was not only the improvement of strength but also the growth of the soul and the understanding of the world.

As their comprehension deepened, the light of the crystal ball became stronger and stronger, and the entire room was enveloped in light. In the light, they saw the true secret of the Spirit Pearl, which was a power that could connect heaven and earth and control all things. And the core of this power was the perfect combination of wisdom and strength.

When they came back to their senses from the comprehension of the crystal ball, they found that the old man was smiling at them. "Congratulations, you have passed the challenge of wisdom," the old man said. "You have used your wisdom and perseverance to unlock the secret of the Spirit Pearl. Now, the Spirit Pearl belongs to you."

Lin Yu and Li Qiang looked up and saw the Spirit Pearl slowly flying towards them, emitting a soft and powerful light. They stretched out their hands and gently held the Spirit Pearl, feeling the endless power and wisdom contained in the Spirit Pearl. At this moment, they knew that all their efforts and sacrifices were worth it.
