The area around the underground river was littered with corroded bones and some clothing that was almost crumbling to rags. Long Qingyang scolded: "Damn, this water isn't just hot, right?" ”

Long Qi also shouted: "It can actually corrode to the point that only bones remain, what kind of water is this?" ”

I kicked the bones and asked, "What happened?" The temperature and level of the river are not constant? ”

Li Ru leaned over to probe the temperature of the water, frowned and said, "The water is gradually getting hotter." It stands to reason that the temperature just now should not cause harm to the human body. And ......," he said, holding some water in his palm, "you see, the water has not corroded my hands." ”

"It's weird! So what's going on with these bones? Did it come from somewhere else? "I shine a miner's lamp on the bones.

"Rushing out from somewhere else? Fuck, I just talked about this river, and we don't know what awaits us yet? Ahsan was so frightened that his face turned white.

Long Qingyang scolded: "Damn, what big things can be achieved without courage!" ”

He looked at the underground river and said, "This water is not so hot for no reason, and there are hot springs in the ground." ”

I said, "When we first arrived, the water temperature was not that high, and the water level was not that high. If there is a hot spring mouth, then it means that the spring must be sucking water back from time to time according to some law. ”

Long Qi said disdainfully: "Nonsense! If it was the spring that sucked the water away, the most it could explain the drop in the water level. How can the water cool down after the spring has re-spewed out? ”

"Oops! So that's it! "Li Ru is overjoyed." What is so gratifying? I asked. Li Ru smiled and said, "I know what's going on with this underground river." No one has to die. ”

As soon as the words fell, suddenly a milky white column of water erupted from the originally tumbling underground river! Long Qingyang stood closest to him, and was splashed on his arm by a few drops of that milky white water, and several large pits corroded on his hand!

"Get out of the way! That's what corrodes people to bones! Li Ru pulled me back the moment the water jet erupted.

Long Qi and Ah Shan hurriedly dragged Long Qingyang, who was screaming, to retreat.

Long Qi pointed a gun at Li Ru's head and scolded, "Damn it! You knew there was something in the river, didn't you? You're trying to kill us? I'll kill you first! ”

Long Qingyang endured the pain and rushed over and kicked Long Qi hard, scolding: "It's almost the same as Lao Tzu killing you!" ”

"The second master ......" Long Qi was very aggrieved.

Long Qingyang continued to scold: "Second, your grandma! Don't you have ears? Can't hear what he just said? "Long Qi is a generation older than Long Qingyang, but Long Qingyang obviously doesn't have a trace of respect for the old guy who has achieved nothing in this matter. Long Qi was so foul-mouthed by the juniors that he didn't even dare to let a fart go.

Long Qingyang didn't dare to touch the wound on his hand, and asked Li Ru, "You said you know what's going on with the underground river?" ”

Long Qingyang's arm was half eroded alive, and his hands were dripping with blood. I even saw meat sauce dripping from his arm. It's so disgusting, I won't have to eat meat anymore. I quickly looked away from my frightened little heart.

Li Ru couldn't look at it either, and said: "After the water column falls, hurry up and wash it with water, otherwise there will be a tendency to spread." ”

Long Qi is considered to be on the bar Li Ru, and he has to contradict Li Ru to say anything: "The water is so hot, do you want to kill our second master?" What a bad idea! ”

Long Qingyang couldn't stand the pain in the first place, so he simply transferred his anger to Long Qi, and shouted impatiently: "Don't you know how to fill out the water first and wash it when it's cold?" Shame on the fuck and shut up! ”

Long Qi closed his mouth in a daze, his throat moving, as if he wanted to say something, but he didn't dare to say it after all.

Li Ru said: "Since you know that there is 'boiling water' in the Ten Thousand Demon Cave, you should also know that there will be an ice pool after the 'boiling water', right?" ”

"Bingtan?" No wonder Li Ru wanted to stop me when I wanted to throw away my clothes just now. Nima: Is this the rhythm of the two heavens of ice and fire?

Long Qingyang nodded, his eyes rolled bonely, and suddenly his eyes shone brightly, and said, "Spring, boiling water, ice pool, I understand." ”

"Understand what?" Long Qi didn't know what to say again.

Fortunately, Long Qingyang figured out the problem, was in a good mood, and did not scold. Long Qingyang said to himself excitedly: "No wonder the water temperature will drop!" Haha, this boiling water and the ice pool are connected! Every once in a while, the spring will suck hot water into the ice pool, and the water temperature will naturally drop and the water temperature of the ice pool will also rise. That's the best time to get through the 'boiling water' and the ice pool. ”

Long Qi said suspiciously: "It's so simple? What was the previous sacrificial legend? ”

Long Qingyang gave him a blank look.

Li Ru said earnestly and persuaded: "Since the brain is long, let's use it occasionally." ”

I couldn't hold back my laughter. Long Qi was annoyed and angry, and glared at us separately. But because of Long Qingyang, it is not easy to attack.

By this time, the milky white water had already fallen. The underground river continued to roll, and it was the same color, unaffected by the milky white water column. Long Qingyang was already quite polite to Li Ru at this time, and asked, "What was the water column just now?" ”

Li Ru shook his head and said, "It seems that soon after the spring spews out the water again, that extremely corrosive white water will spew out. But I don't know exactly what that white is, maybe it has something to do with the demon wolf. ”

Ahsan, who was much more eye-catching than Long Qi, immediately automatically and consciously turned out everything that could hold water from his backpack and went to the river to catch the water. Just wait for the water to cool and help Long Qingyang clean the wound.

Long Qi was still haunted by the question just now, and asked: "Second master, is it groundless to say that the sacrifice is groundless?" ”

Long Qingyang ignored him, stared at the turbid underground river and frowned, "What is the activity law of the spring?" It just sucked the water in once, and God knows when it will wait until the next time? Fuck it! ”

I saw that I was idle, so I said to Long Qi, "You want to know where the statement of sacrifice came from?" ”

Long Qi glared at me angrily: "It's about your birds!" You know? ”

I smiled and said, "Of course I do." ”

Long Qi was confused and said, "How do you know? I smiled again and said seriously, "Because since I have a brain like this, I decided to use it once in a while." ”

"Fuck it!" Long Qi was furious. Long Qingyang turned his head and looked at him coldly. Long Qingyang originally wanted to use us as sacrifices to open the way, but after coming in, he found that their understanding of the Ten Thousand Demon Cave was really about zero. Li Ru's understanding of the Ten Thousand Demon Caves was a lifesaver for them. Naturally, he couldn't allow Long Qi to destroy us while we were still useful.
