"A river......! Two problems with a river ......! Li Rui's eyes widened suddenly, as if he had grasped something.

"Brother Li, what are you talking about? Have you ever heard Caifeng tell you a story? And just as Li Rui was pondering, Yuan Caifeng's dissatisfied voice suddenly came.

Li Rui hurriedly looked at Yuan Caifeng, and suddenly found that Yuan Caifeng was pouting dissatisfied, looking at him with a resentful expression. Li Rui hurriedly said, "Hehe, Caifeng said it so well, I heard it all!" ”

"Really?" Yuan Caifeng was dissatisfied because Li Rui didn't pay attention to her story, and now when she heard Li Rui's explanation, she immediately asked in disbelief.

"Of course it's true!" Li Rui's expression at this time seemed very serious, but there was a wry smile in his heart, and in order not to dwell on the current problem, Li Rui hurriedly said with a whim, "Caifeng, I'll come up with a question to test you, how about it?" ”

"What's the problem?" Yuan Caifeng immediately looked at Li Rui curiously and asked.

"That's just eight words, you're fine. Two problems with one river! Li Rui looked at Yuan Caifeng and said.

Yuan Lengshan asked Li Rui to help pass down a sentence, and Li Rui had already completed the task, so he didn't need to think about the meaning of this sentence anymore. But now that Yuan Junlang has joined the Maoshan Sect with his whole family, then the words handed down by Yuan Lengshan are not outsiders, but belong to the disciples of the Maoshan Sect.

Li Rui even suspected that this sentence should actually be the fate of Yuan Junlang's family, or it can also be called immortal fate. For the sake of his own disciples, Li Rui is thinking about and deciphering this sentence all the time.

"Two problems with a river? What's the problem? Yuan Caifeng was directly stunned by Li Rui's words.

"Here's the problem. Two problems with one river. After you heard this, did you have any thoughts? Li Rui didn't know how to explain it. Just asked vaguely.

"Thoughts, I don't have any ideas. What are the two problems of a river? What does that mean? Yuan Caifeng was really a little confused by Li Rui's question.

"You can do it. You take this sentence for a riddle. A riddle without any hints. Think about what kind of information you can find in this sentence! Li Rui continued unwillingly.

"Two problems with one river...... Two problems with a river? If there are really two problems with a river, then everyone should be most concerned about where it starts and where it ends. Yuan Caifeng chattered for a while, and then suddenly said.

"What? The source and the end? Li Rui listened to Yuan Caifeng's words, and his eyes suddenly lit up.

"Sect Master, this source and end ......!" At this time, Qiao Weiqiang also looked at Li Rui with a surprised expression on his face.

The two problems of a river, this sentence is not only thinking about Li Rui alone. Qiao Weiqiang, Tang Lie, Wang Jun and Zhao Guanguan are actually also thinking. But they didn't have a clue.

However, when Yuan Caifeng said the words "source and end", everyone felt that their eyes lit up almost at the same time.

Li Rui and the others are all cultivators, and after cultivating, not only will their physique be enhanced, but their memory and wisdom will also be greatly developed, so ordinary cultivators are very smart.

Now, almost unanimously, they all unleashed their divine senses and probed into the depths of the Immortal Lake. Among them is Li Rui. Moreover, Li Rui's divine sense was strong, so his speed of investigation was also the fastest, and he entered the depths of the Immortal Lake almost instantly.

"Huh? Nimbus! Ha ha. The secret is here. Li Rui was almost enlightened at this time, so when he was about to approach the bottom of the lake, he suddenly felt that there was a faint aura in a certain position in the depths of this lake.

Subsequently. After Li Rui's careful investigation again, there was a big spring in the place where there was aura, and it was constantly tumbling outward with groundwater.

"This is supposed to be the source of the Immortal Lake. As for the end ......! If the lake does not have a river channel that flows outward, then the water in the lake cannot flow anywhere else. Then it can only rely on its own penetration to consume the gushing water, and the bottom of the lake should be regarded as the end of the lake. In that case, this is the ......! "After some careful probing. Soon, Li Rui's divine sense was concentrated in one place.

And it wasn't just Li Rui, then Qiao Weiqiang and Tang Lie also searched for their divine senses, and the divine senses of several people met at a certain location at the bottom of the lake.

"Sect Master, here! I can feel the aura fluctuations here! Qiao Weiqiang excitedly communicated with Li Rui in the form of divine consciousness transmission.

"Master, I can also feel that there should be a formation here!" Tang Lie also expressed his opinion.

"Yes, there is indeed a formation here." Li Rui was still very satisfied with Qiao Weiqiang and Tang Lie's judgment.

"Sect Master, then hurry up and break this formation!" Qiao Wei couldn't wait.

"Master, let me break it!" Tang Lie asked for battle on the side.

"No, don't act rashly. This formation is not easy to break. It also comes with a self-destruct design, once someone breaks the formation with violence, then this formation will produce a self-explosion, and the power of the self-explosion is enough to blow us all up! Li Rui hurriedly said.

"Ahh Tang Lie listened to Li Rui's words, and suddenly broke out in a cold sweat. Even a few people invariably took back their divine senses, for fear of accidentally detonating the formation.

Now there are really few people in the entire Maoshan Sect who know the formation, but if the cultivator does not understand the formation, it will cause certain difficulties for the road of cultivation, so Li Rui has popularized the knowledge of the formation in the Maoshan Sect, Li Rui's goal is that even if the disciples cannot become formation masters, they will not know anything about the formation, but Qiao Weiqiang has obviously not started to learn the formation, although Tang Lie has learned a little, but he is obviously not proficient.

"From this formation, it can be completely seen that Yuan Lengshan is actually still a formation master! The formation set up by a formation master in the late Mahayana period, it is no wonder that thousands of years have passed, and it is still so rigorous and meticulous. After Li Rui stopped Tang Lie's recklessness, he studied this formation alone for a while before leaving.

"Brother Li, what's wrong with you?" When Li Rui and them used their divine sense, their physical bodies would lose their minds for a short time, so Yuan Caifeng saw Li Rui and their stunned appearance, and immediately asked puzzled.

"Haha, good news, let's go, let's go back first!" Li Rui took his divine sense back in time, and then excitedly walked back with Yuan Caifeng.

Yuan Caifeng didn't know what to do, but he also knew that Li Rui and they had encountered something good, so he happily took his younger brother and followed Li Rui back.

However, just as they were about to arrive home in high spirits, they suddenly heard a loud noise. (To be continued.) )
