Chapter 2570: 2570 ## Chapter 2570: Fourth-Level Formation, Lightning Formation One month is the time for thirty cycles of the moon and sun. The opening of Leishan Mountain this time will last for one month. Lin Moyu knew in his heart that if he could not solve the mystery within one month, he might be trapped here forever. There were many more puzzles ahead, and the one in front of him was just one of them, so he had to hurry up. There were hundreds of formations in the jade card, but fortunately, there were only more than twenty third-level formations. Among these, only two were related to thunder: the Thunder and Fire Formation and the Wood Thunder Formation. Thunder and fire belonged to Yang, and wood thunder belonged to Yin. Lin Moyu started to learn the Wood Thunder Formation directly. The remnant soul looked at Lin Moyu quietly without saying a word. He did not disturb Lin Moyu but just waited patiently. He had waited for ten thousand years, and his patience was unimaginable. Such a short time was nothing to him. Five hours later, Lin Moyu put away the jade card. One by one, the origin crystals popped out, and more than 300 first-order origin crystals formed a Wood Thunder Formation around the large monument. The Wood Thunder Formation was activated, and bursts of thunder were heard. The thunder was low, in sharp contrast to the thunder in the Leishan Mountains. When the Wood Thunder Formation was activated, the thunders around were immediately attracted and hit the Wood Thunder Formation. The Wood Thunder Formation could not resist the powerful thunder at all and was broken in an instant. As a third-order formation, the thunder attracted by the Wood Thunder Formation was several times more powerful than the previous Water Mine Formation. Moreover, Lin Moyu deliberately arranged the Wood Thunder Formation around the large monument. When the Wood Thunder Formation was broken, the thunder also drilled into the large monument. The large monument was activated, shining, and countless words were revealed. Lin Moyu seized the moment and checked it immediately. This time, because the thunder power was strong enough, the duration of the large monument’s illumination was much longer, and the inscriptions on the monument were all revealed. After shining for more than 20 seconds, the inscriptions became dim again. At this moment, Lin Moyu looked strange, "It turned out to be like this!" Twenty seconds was enough for Lin Moyu to remember the entire inscription. He did it, and wrote down the contents of the inscription word for word. What made him feel strange was the content recorded in the inscription. The inscription recorded two parts in total: one was a formation, and the other was a secret technique. The formation was called the Thunder Induction Formation, a fourth-level formation, and its function was to attract thunder. It needed to be placed in a place full of thunder to work. It could attract a lot of thunder, whether it was used to fight enemies or for practice, and it was very useful. And most importantly, the thunder it attracted would not cause harm to itself. Lin Moyu realized that this was the correct way to activate the inscription. The method of using Yin thunder to attract Yang thunder was actually not correct. The other secret technique was the Thunder Secret Method, which required the corresponding laws to cooperate. Lin Moyu had not learned the laws of thunder, so he could not master it in a short time. What he could master was the Lightning Formation, and the formation was also the key to solving this problem. "It seems that this senior’s legacy should be the formation and the art of thunder." "To solve this problem, you must master one of the two." Lin Moyu understood and immediately began to study the Lightning Formation. The fourth-level formation is much more difficult than the third-level formation, and even for him, it takes some time. A stream of clear air fell from the void and penetrated into his body. Lin Moyu knew that Xiaowu was still using the Great Way of Luck to improve his luck. Lin Moyu also used the Explosive Luck Technique to improve his luck to the limit. Luck turned into a dragon, ringing in his ears. Lin Moyu’s mind was completely immersed in the comprehension of the formation. With the dual blessing of luck and the Great Way of Luck, his comprehension speed accelerated again. All kinds of difficulties were broken and did not constitute any obstacles. The remnant soul, who had been motionless all the time, suddenly opened his eyes and looked at the top of Lin Moyu’s head, muttering to himself, "The Great Way of Luck, after many years, someone else has comprehended the Great Way of Luck." "This boy’s luck is also amazing. If he doesn’t die, his future is limitless!" "Perhaps, he has a chance to touch that realm!" These words could only be heard by the remnant soul himself, and Lin Moyu did not know. If he knew, Lin Moyu would probably be shocked, and his view of the remnant soul would completely change. 𝒇𝙧𝙚𝓮𝙬𝙚𝓫𝒏𝓸𝓿𝓮𝒍.𝓬𝙤𝓶 The remnant soul can only have a part of the body’s memory, and which part of the memory it can have is determined by the body. And the remnant soul in front of him, his memory is obviously very complete. Such a remnant soul is extremely abnormal. After the remnant soul finished speaking, he closed his eyes again and continued to remain silent. Lin Moyu spent five hours to completely master the formation. Then he spent another hour verifying it in his own rule world. After confirming that it was correct, he took out a large number of origin crystals and began to arrange the formation. He still arranged the formation around the large monument, but this time Lin Moyu was very careful to ensure that the formation was square. The fourth-level formation consists of more than 600 formation nodes, and each formation node requires an array device as the formation eye. The formation device can be a magic weapon, various materials, origin crystals, or even stones. The difference is that the different levels, qualities, and properties of the formation devices will directly affect the power of the formation. When the formation is running, the formation device also needs to withstand the pressure brought by the formation. The higher the level of the formation, the higher the requirements for the formation tools. Lin Moyu still used first-order origin crystals, which were the best materials he had on hand for the formation. The entire formation used the same first-order origin crystals as the formation tools, making the formation more harmonious. Although it could not further enhance the power of the formation, it was neither good nor bad. After the previous consumption, he still had two thousand first-order origin crystals on hand, so he had to use them sparingly, not knowing how many he would need in the future. After half an hour of busy work, the formation was finally arranged. Lin Moyu activated the formation, and the Lightning Formation started running, releasing a strange breath. In the surrounding space, countless thunders were attracted and fell towards the Lightning Formation. Lin Moyu felt the difference. The previous thunders struck the Wood Thunder Formation like a sharp weapon, treating the Yin thunder as an enemy and wanting to split it into pieces. But now, the thunder fell on the Lightning Formation with a hint of gentleness, not wanting to smash it. A large number of thunders fell into the Lightning Formation and gathered together, increasing in number. The Lightning Formation gradually evolved into a sea of thunder. The Lightning Formation was built around the monument, and the monument was also surrounded by thunder. Finally, the monument was completely swallowed by the sea of thunder. At this moment, the monument was fully activated. A beam of light shot out from the monument, and the thunder in the distance split like a curtain, revealing a passage. The remnant soul slowly opened his eyes, "Let’s go." As he said this, he walked towards the passage, and Lin Moyu hurriedly followed.
