Back in the hall, before arriving at the second portal, Cheng Ling said, "Miss Qin, I'm good at breaking formations and restrictions. You'd better follow me."
Qin Zijin nodded silently. She actually had no intention of going in first. Somehow, after being with Cheng Ling, she felt lazy and accustomed to obeying the other party's orders in everything.
Seeing that she agreed, Cheng Ling walked into the door first.
Inside is a square inner room with many fairy weapons and some unknown treasures piled densely on the ground, but they all seem to be broken. In the middle of the inner room, there is a stone tablet about ten feet in diameter standing. In front of the stone tablet is an oval-shaped thing like a bathtub.
Both of them looked at it and were stunned. What was going on? What was the significance of the broken treasures and stone tablets, and such a bathtub in the middle.
Qin Zijin took a look and said, "Is there some mystery on that stone tablet?"
Cheng Ling's eyes flashed blue, but he didn't see anything special on the stone tablet. He shook his head and said, "It's nothing special. Let's walk around the inner room and search first."
Qin Zijin nodded, and the two began to search along the edge of the inner room. The inner room is not big, and the walls on both sides are made of the same materials as those outside the city. They are all huge black stones.
But when Cheng Ling came to the back of the stone tablet, he suddenly saw three light red words carved on the stone tablet, "Cultivation Pool."
"Cultivation pool?" Qin Zijin also saw it and hurriedly took a few steps forward. After a moment, he said happily: "Could this be the training pool passed down by the ancient sword sect?"
"What? Miss Qin, do you know?"
Qin Zijin said: "I once heard the master say that the ancient sword sect once had a rare treasure, which is this training pool. Its function is to convert everything in the world into energy for monks to improve their realm."
"And this energy is very pure, not much worse than the Immortal Marrow Liquid. It can be said to be a supreme treasure for improving your cultivation."
Cheng Ling asked: "You mean, these immortal weapons became dilapidated because of the training pool?"
"Yes, these immortal artifacts were obviously thrown here because someone wanted to convert them into pure energy. However, some shocking incident occurred. All the people in this ancient city disappeared without a trace, and even this treasure was abandoned. "
"So what do we do?"
"It's very simple. Although these fairy weapons and treasures are broken, they can still provide a lot of energy. Just throw them into the training pool and you will see if they have any effect."
When Cheng Ling heard this, he immediately took action. He was worried that his cultivation level was progressing too slowly. How could he let go of such a treasure as the training pool?
"The Romance of Fairy Wood"
There are tens of thousands of broken immortal weapons and treasures in the inner chamber, all of which are still in the cultivation pool. Soon, the broken immortal weapons and treasures seemed to be melted, turning into strands of liquid, flowing out and pouring into the training pool.
It's just that these things have been eroded for a long time, and their energy has been lost too much. After throwing all the treasures into the pool water, they were barely flush with the pool wall. Bubbles rolled in the pool water one by one, and a huge energy flow came over the surface.
The two of them were overjoyed. They didn't expect that this training pool was really effective. But soon, they felt a little embarrassed again. The training pool was not big. It was only one foot in diameter, which could only accommodate one person.
People soaking in the pool would seem too crowded if there were only two of them.
Besides, they are men and women, so it is impossible for them to bathe together...
Cheng Ling coughed dryly and said, "You use it first, and I'll go out for a walk."
After saying that, he also placed a few shielding restrictions beside the training pool, which at least made Qin Zijin feel more comfortable.
Qin Zijin glanced at him and said, "Okay, I will call you after I finish my promotion."
Cheng Ling nodded slightly and left.
After walking out of the inner room, he glanced at the two doors. The two women were practicing hard, and he was bored for a while. Originally, it was possible to absorb the inner elixir of the sea clan to improve one's cultivation level, but with such a treasure as the training pool, there would be no need to waste natural resources.
"It's been several months. I wonder how Second Senior Sister is doing." His mind moved, and his consciousness entered the space inside his body.
In the land of attribute elves, seeing Chu Yulu already killing the wood attribute elves, he must have reached perfection with his golden spiritual root.
After she killed the wood-attribute elf who was probably in the middle stage of the Immortal Emperor, Cheng Ling appeared, smiled slightly, and asked: "Second Senior Sister, I see that your cultivation progress is not slow. How about it? How many kinds of skills have you perfected?" Spiritual roots?”
When Chu Yulu saw him suddenly appearing, she said in surprise: "Junior Brother Cheng, you are here again. Not bad, the three systems of Golden Spiritual Root, Water Spiritual Root and Fire Spiritual Root are currently full."
Cheng Ling was surprised and asked doubtfully: "It's so fast. You're so lucky!"
There are not many opportunities for ordinary attribute elves to derive spiritual roots. Moreover, even if they are derived, it will take a long time to upgrade the spiritual root attributes to the ninth level. I didn't expect Chu Yulu to do it so quickly.
Chu Yulu smiled and said: "Yeah, I didn't expect that I happened to encounter a group of water elves and fire elves a while ago, and they were full after killing them continuously. But I found that there are a lot of five element elves here, but the rest There are very few attributes.”
Cheng Ling nodded and said: "Yes, most of the attributes of heaven and earth belong to the Five Elements. These five attribute elves are popular, and the other ones are hard to find. By the way, Second Senior Sister, it will be very difficult to keep killing attribute elves. It’s boring, you can go out for a walk occasionally, just tell Hu Yue if you need anything.”
"It's okay. This kind of opportunity is rare. I'd better buy time to derive the other spiritual roots as soon as possible!"
Cheng Ling had no choice but to say: "Okay then, you continue to practice and I won't disturb you."
After saying that, his mind moved and he returned to the real space.
He raised his eyes and looked at the portal where the Dark Monument was located, and murmured: "When I first comprehended the Great Light Monument, it seemed that many monks were doing it together, but nothing happened, so why not first comprehend the secrets of darkness."
He did what he thought of, and with a movement of his body, he stepped into the portal.
Not long after, I saw Su Nianli sitting cross-legged next to the sword monument from a distance, still studying with all his strength. He did not come forward to disturb, but came to the other side of the stone monument. The two stopped when they were more than ten feet away, and his spiritual consciousness slowly penetrated into the dark monument.
As soon as he entered, he felt his body shake, and what he saw before him was boundless darkness. The darkness was so deep and so pure that Cheng Ling could not help but think of the scene when he understood the Light Sword Monument. At that time, it seemed as if he had entered a world of pure light, with only light and nothing else.
Now that he was in darkness, Cheng Ling had a feeling that this darkness
Darkness and light are similar in that they are both so pure, so profound, so... domineering. Light and darkness are opposites, just like water and fire, and they are more absolute than the opposition between water and fire.
Where there is light, there will be no darkness; where there is darkness, there will be no light. It is a well-known knowledge that light and darkness cannot coexist. If you study more deeply, you will realize that light and darkness are actually the same in nature.
Wandering in the darkness, he couldn't see, hear, or even smell, but Cheng Ling had a feeling. Gradually, he seemed to be integrated with the darkness, becoming a part of it and becoming a part of it. A tiny particle in the darkness, rising and falling in the dark ocean.
The light mystery in the spiritual world emits strange fluctuations. Waves of bright light bloom out, illuminating and filling the entire spiritual world. It contains all the power and seems to assimilate all the power. , tightly adhering to the barrier of the spiritual world, forming a layer of light barrier.
The endless darkness and power wanted to enter Cheng Ling's spiritual world, but they were blocked by the light barrier set up by the Mystery of Light, unable to enter at all. The two confronted each other, and the Mystery of Light glowed in the spiritual world.
Darkness and light cannot coexist!
Under normal circumstances, in this situation, the dark mysteries and the light mysteries will definitely cause a great conflict, which is quite life-and-death. But Cheng Ling had already prepared and understood both mysteries to 50% to maintain their balance.
Therefore, the confrontation between the dark mysteries and the light mysteries is not as fierce as imagined. It seems very fierce, but it is not as decisive as life or death.
Moreover, from the Monument of Darkness, you can also find clues to improve your understanding of the mysteries of light. The darkness was endless, swimming in it with no beginning or end, and Cheng Ling fell into an epiphany.
Darkness, black, pure black, cannot tolerate other colors, which shows that it is very domineering and cannot tolerate other powers. If night falls, covering the sky and the earth, everything in the world will be included in the darkness and will not disappear. Just submerged in the black, in step with the darkness.
In other words, in addition to being domineering, darkness also has the characteristics of tolerance. Darkness can contain everything except light. When light appears, darkness will retreat or light will disappear.
Light is also very overbearing. It covers everything it passes and cannot tolerate other colors. Only pure light remains. But in the light, other things can exist, just like daylight. Wherever it goes, all light Show, therefore, in essence, light and darkness actually have something in common, the same domineering, the same tolerance...
Under the sudden enlightenment, the slightest hint of enlightenment appeared, and Cheng Ling gradually understood something, but he couldn't explain the unknown mystery.
With his mind moving, he combined his tyrannical mental power with his sword intention to suppress the light mysteries and attract the dark mysteries into the spiritual world. However, the power of the light mysteries was too strong. No matter how hard Cheng Ling exerted his strength, it was difficult to suppress it. Instead, There is a kind of momentum that if you are stronger, I will be stronger.
After continuing to fight for a period of time, the secret of light could not be suppressed.
He had to stop and start thinking: It seems that blind suppression cannot achieve the effect of improvement. Light and darkness are like the two poles of things, endless loops. To maintain their balance, they must be improved simultaneously.
