**Chapter 1639: If You Don't Come Down, I'll Force You Down**
Lin Moyu didn't know if he was the first to grab nine clusters of black water at once, but he estimated that not many people could do it. The rune power of the nine clusters of black water would stack, requiring him to endure nine times the illusion. Coupled with the attacks of the rune beasts, it would be extremely dangerous if he couldn't react in time.
However, Lin Moyu didn't care at all. He declared his strength to the Black Rain Secret Realm with an extremely domineering posture. The rune beasts rioted, causing huge waves in the ocean, and tens of thousands of rune beasts rushed out of the sea.
Lin Moyu remained calm, not even summoning more skeletal god generals. Only one skeletal god general stood by his side, using the Golden Armor Rune to protect both of them. No matter how fierce the rune beasts' attacks were, they couldn't do anything to Lin Moyu.
He forcibly grabbed the nine clusters of black water. Once out of the water, they quickly turned into nine black crystals. With ten portions of black water in hand, the task was complete.
The next moment, Lin Moyu took out the "Symbol Language" and continued studying the runes within. The "Symbol Language" was vast and profound, and the more Lin Moyu read, the more he found it fascinating. It contained only 180 high-level runes, but each high-level rune was the general outline of a certain type of rune, from which many high-level runes could be derived.
In the most extreme case, Lin Moyu had derived 36 high-level runes from a single rune in the "Symbol Language," and each derived rune was a high-level rune. Lin Moyu also discovered that as he mastered more runes, he could go back and derive new runes from the ones he had previously learned.
These discoveries made Lin Moyu realize that the "Symbol Language" was not simple. There might be many secrets within it that he had yet to uncover. It made sense; anything valued by the big shots in the Other Shore Realm wouldn't be simple.
After a day of heavy rain, it gradually weakened but didn't stop completely, turning into a light rain that continued for several days. The rune beasts continued to attack Lin Moyu, who had become a thorn in their side. The skeletal god general tirelessly killed the rune beasts, and countless rune beasts had died under its sword over the past few days.
After three days of continuous light rain, it suddenly stopped. Another light rain fell, lasting only a day, followed by five days without rain. On the sixth day, the second light rain began, also lasting a day, followed by another five days without rain. Then, another heavy rain fell, and clusters of black water reappeared in the clear ocean.
Not only in the ocean, but black water also appeared in all the water bodies in the secret realm during the heavy rain. After a day of heavy rain, it stopped again. The cycle repeated every 18 days: two light rains and one heavy rain. This cycle continued for three rounds without any torrential rain.
Without torrential rain, it was impossible to enter the second stage. No one knew when the torrential rain would come. While others hoped to avoid torrential rain, Lin Moyu was waiting for it. Over time, the number of rune beasts attacking Lin Moyu began to decrease. The ocean gradually calmed down, as if the secret realm had become accustomed to Lin Moyu's presence.
Lin Moyu had been in the secret realm for five cycles, over a hundred days. During this time, apart from completing the task, he spent most of his time studying the "Symbol Language." After 108 days, he slowly opened his eyes, a hint of excitement flashing in them. "I understand, I finally understand."
Through repeated study and comprehension, Lin Moyu had found the pattern and understood the true essence of the "Symbol Language." He once thought that the "Symbol Language" contained only a portion of high-level runes, not all of them. He had indeed found high-level runes in the Symbol Master Association Tower that were not in the "Symbol Language." But now, he realized he had underestimated the "Symbol Language."
The "Symbol Language" contained all high-level runes. The high-level runes he saw in the Symbol Master Association Tower were all included in the "Symbol Language." He just hadn't mastered them yet. The "Symbol Language" recorded 180 general outline runes, each of which could be broken down into 36 high-level runes, totaling 6,660 runes. These runes were more comprehensive than those in the Symbol Master Association Tower and, according to Lin Moyu's understanding, should include all high-level runes in the great world.
These high-level runes could be fused with each other and with basic runes. The combinations were endless and uncountable. The final rune that could be fused depended on each person's comprehension and mastery of runes. For example, his Golden Armor Rune was composed of one high-level rune and ten basic runes. The Golden Armor Rune was already at a high level, and to further enhance it, more useful high-level runes would need to be integrated.
No matter how they were fused, the ultimate goal was to exhibit multiple abilities with a single rune. A single rune could even replace complex formations. One rune could form a formation! It could also make the rune stronger, integrating it with the soul and rules, transforming it into a more powerful ancient rune, turning decay into magic, and possessing incredible power.
Unknowingly, Lin Moyu's understanding of runes had reached another level. He no longer limited himself to the runes themselves but began to observe from a detached perspective. When you're in the game, you can't see clearly; as a bystander, you can see everything. He gradually understood the essence of runes.
Lin Moyu didn't realize that the Dao Rhythm he experienced had already touched the highest level of the Rune Dao. The benefits brought by the Dao Rhythm were subtly and gradually manifesting. On the 93rd day in the secret realm, there was no rain, and everything was calm. The rune beasts no longer leaped out of the sea to attack Lin Moyu.
Lin Moyu looked at the sky, and his Soul Eye silently opened. The sky was filled with dense runes, all fragments of ancient runes. Lin Moyu's gaze gradually became unfocused. He didn't try to forcibly memorize these runes. The ancient runes contained the power of rules, which he couldn't forcibly memorize at his current level. He didn't need to memorize these runes; he just needed to find the pattern of their combinations.
Whether it was light rain, heavy rain, or torrential rain, they were all controlled by runes. Since the torrential rain was delayed, he decided to make it rain himself. His finger seemed to move unconsciously, and a simple rune naturally formed. It was a spell-type rune, a basic rune called "Gentle Rain." This rune could make it rain in a specific area.
Lin Moyu locked his gaze on a part of the sky and softly chanted. The Gentle Rain Rune flew out like lightning. The rune exploded, instantly activating the runes in the sky. A light rain quickly began to fall. On the 93rd day, it started raining again in the secret realm. This wasn't supposed to be a rainy day; there were still two days until the next light rain. But under Lin Moyu's rune, the rain fell as expected.
