Li Yun immediately retreated from the underground river.
When the two of them heard the loud sound of water, they immediately retreated to the shore.
The huge underground river water turned into a white wave that was five to six meters tall and rushed out fiercely.
Although the three of them moved very quickly, the surging underground water still splashed on the three of them.
Just a little bit of it could feel the huge heat.
"F * ck, it's f * cking hot!"
Black Blind could not help but curse.
"You really came to soak in the hot spring."
"The water that spurted out is much hotter than the water in this underground river.”
Xie Yuchen said lightly.
"The three of us can still wade through the water of this underground river, but once we get hit by the boiling water that spews out, we'll be cooked!”
Li Yun said with a smile. Although the three of them were in a sorry state, an optimistic heart was essential.
The huge current immediately raised the water level of the underground river by a section. At this moment, everyone finally understood why there was no stalactite at the top of the underground river. It must be because the underground river would erupt with large amounts of water from time to time, grinding the stalactite at the top flat.
"According to this situation, we can't walk through this underground river. Look, the water level is starting to drop.”
Black Blind analyzed.
Li Yun nodded as he watched the water level slowly drop.
It was unknown how long this underground river was, and how long it would take to reach the end.
With the power of this huge wave, they would probably be washed back before they could reach the end.
Just as Li Yun was starting to get a headache, Xie Yuchen noticed a few chains on the left.
"We should be able to go up from here."
Xie Yuchen grabbed a chain and pulled it. The chain was very strong.
These were a few iron chains hidden in the dark that led straight to the top of the underground river. Li Yun shone the Wolf Eye flashlight on them. As expected, the place where the iron chains extended was not capped.
"Will this thing trigger some kind of mechanism?”
Black Blind stroked his chin and asked worriedly.
"Don't worry, it won't. If it triggered any mechanism, it would have been triggered by the few times Xie Yuchen pulled it.”
With that, he put everything into his backpack, grabbed the chain with both hands, and began to climb up.
However, after being washed by the huge waves for a long time, the rock wall had become extremely smooth. Li Yun wanted to climb on the rock wall, but it was indeed difficult for him to take half a step forward.
Xie Yuchen smiled and quickly climbed up with his swift movement technique.
Li Yun took a closer look.
Xie Yuchen didn't rely on the rock wall. Instead, he relied on the bumps of the chains and cleverly exerted force to maintain the entire chain at a vertical level as he climbed quickly.
Black Blind was the same. Even though he didn't have Xie Yuchen's practical movement technique, Black Blind relied on his superhuman arm strength and stepped on the uneven parts of the chain to forcefully pull the chain up.
"Do you want me to carry you up later?”
Black Blind asked with a smile.
Li Yun smiled.
Xie Yuchen's actions just now. Li Yun saw everything clearly.
The technique wasn't very complicated, so Li Yun directly memorized it.
Following Xie Yuchen's movements, Li Yun also climbed up at an extremely fast speed. Soon, he was on par with Black Blind.
Compared to Xie Yuchen, Li Yun's movement technique was much less flashy. It looked no different from ordinary climbing.
Black Blind was stunned.
"Is this kid playing dumb?"
Looking at Li Yun who was climbing much faster than him, Black Blind could not believe his eyes.
Xie Yuchen heard the iron chain suddenly ring at a fast pace and couldn't help but turn his head to look.
Wasn't Li Yun using the movement technique of the Xie Family?
Although Li Yun's movements were somewhat different from his own, this was indeed the movement technique of the Xie family.
Although this climbing technique wasn't very complicated, the requirements for dexterity and strength were extremely strict.
Li Yun's robust figure was even faster than Xie Yuchen's.
At the same time, Xie Yuchen looked at Li Yun with admiration.
"You two young people, don't you know how to feel sorry for me? You climbed so fast!”
Seeing that the two of them were far ahead of him, Black Blind could not help but complain.
However, Black Blind was not to be trifled with. He used his agile legs to increase his already fast speed by another level.
However, he still couldn't compare to the two young men.
Climbing the chain with his bare hands was an extremely energy-consuming exercise.
Even with Li Yun's strengthened physique, he still felt a sense of weakness in his limbs.
At this moment, a loud sound of flowing water entered their ears.
Could it be that the water was going to rush down from above?
The expressions of the three of them immediately turned ugly.
They had already climbed so far. If there was another wave of boiling water above, they would not be able to avoid it. What awaited them was the fate of being cooked!
However, the three of them soon realized that their worries were unnecessary.
When they reached the end of the underground river, the scene in front of them suddenly widened. The underground river seemed to have been cut off and disappeared for some reason.
At this moment, Li Yun suddenly realized that this was a waterfall!
