The section of the underground passage that we had walked through before, according to the judgment of several of them, was parallel to the underground river.

After careful deliberation with Chen Yuqing, Yun Chu further came to the conclusion that the dark river was northwest of our travel direction.

While we were resting and fighting, Yun Chu had already used gravel to draw a figure on the rock wall.

A few of us gathered around to take a closer look at the oddly shaped patterns on the stone wall.

I looked at the marks made by Yun Chu on the rock wall, and asked with some concern, "You don't want to ......?"

He nodded, raised his hand to beckon Chen Yuqing over, and the two of them glanced at each other.

Yun Chu pointed to a marker in the figure, his eyes flashed, and said, "You are here with your strength." “

Chen Yuqing groaned for a moment and nodded: "When I push the stone wall, a few of you, stay away." “

Exiting more than ten zhang away, I first heard a low voice, and then there was a sound immediately, only to see Chen Yuqing knock on the rock wall with his palm, and suddenly the dust rose up, and then the gravel fell on the ground.

The pit was filled with smoke and dust, "cough cough cough" A few of us shook our sleeves hard to drive away the dust, and covered our mouth and nose with one hand, I was guilty in my heart, and my expression was depressed: This way is really not environmentally friendly! It's just feeding us with dirt!

When the smoke and dust finally dissipated a little, Lan Tian let out a second palm, which was good, the tunnel once again became a natural garbage dump, and the falling gravel was almost half a person high.

The duo came out together to break down, but they still didn't get the situation we wanted.

Yun Chu brushed off the dust on his body, and once again knocked on the rock wall that was more uneven than before the force was destroyed, he carefully compared, and turned to Chen Yuqing and Lan Tian and said, "The last blow, who of you will come?" ”

The final blow? Doesn't that mean success? The competitive Chen Yuqing raised his hand without hesitation and said, "I'll come." ”

"This time, you stay farther away." As he spoke, he was about to take out his palm, but suddenly withdrew it, and said suspiciously, "Why can't I use a weapon, young master, my hand hurts." “

Yun Chu said expressionlessly: "When did I say that you can't use weapons, it's you who can do it yourself." “

"Hehe," I said, "crow, use a sledgehammer to smash stones." What will be used as a sledgehammer for you at this time, and there is no blacksmith shop in this cave. “

After a round of inspection, I found that there were no suitable tools for smashing stone walls. Chen Yuqing had no choice but to shoot again with a bitter gourd face.

As on the previous occasions, there was a heap of rocks that almost blocked the entire passage, but the rock wall was still standing there in good shape, a thick piece. Tightly, there are no flaws.

"What's going on, it's not that you miscalculated, with our efforts, it doesn't make sense to break it." Chen Yuqing said strangely, looking at Yun Chu with some suspicion: "Didn't you say that you were about to break through?" “

Yun Chu didn't answer. He took out a short sword from his bosom, and the sword was made of unknown materials, and it shone faintly with silver light. He stepped forward and measured the rock wall.

Saying that it was too late, the silver light flashed in front of my eyes, and the short sword sank straight into the stone wall, Yun Chu turned around and smiled sincerely at Chen Yuqing. "Try again."

He said this sentence by looking at the blue sky on the side, who was thin-skinned. Consciously came up to help.

I watched my brother's hand push the hilt of the short sword with lightning speed, only to feel that the sword had gone in a little more.

"Boom" accompanied by a loud bang, the passage finally collapsed a corner, and in an instant the cold wind poured in, feeling eerie, and it was a very uncomfortable breath.

Through the crumbling stone wall, the underground river not far away shimmered with phosphorescence and flowed before our eyes.

Ah Si took the lead, followed by a few people behind, and when they moved the gravel of the passage away, and when they crossed the pile of obstacles, I couldn't help but glance back at the place where we had broken the wall.

Sure enough, as I guessed, Yun Chuxuan's focus was precisely the thinnest part of the entire rock wall, which was covered by thick stone layers all around, and for some reason that place happened to be a very weak place in the natural formation.

Previously, he struck the rock wall with guò, thinking that it was to determine the weakest point of force based on the sound it made, including several previous attempts, but also to make this point of force more accurate, and finally the seemingly inadvertent short blade was actually slashed on the edge of the knife.

Fighting the power of nature with manpower is bound to be a very tiring thing.

Seeing that the stone wall had been broken and the underground river was in front of him, the first thing to do was to stop and rest.

Ah Si volunteered to help us explore the flow of the dark river, and watched his figure disappear into the bend of the dark river, and a few of us sat down.

Lan Tianfang and Chen Yuqing were both pranayama, and the ninth princess also leaned on a stone pillar to sleep.

Yun Chu was wiping the hero who had helped us break through the stone wall, and I took the short sword from his hand and picked it up to examine it by the light of the torch.

"Beware," he said softly, but with swift movements, he snatched the tip of the blade in his direction, "this sword is sharp, beware of broken hands." ”

He placed his sword on the rock beside him, took out a scabbard inlaid with colored stones from his sleeve, and carefully put it in.

"Xiao Ling'er, when we come back from the exploration in a while, we will rush in the direction of the underground dark river, don't leave me." Yun Chu sat upright without moving, and whispered to me.

"Could it be that there is something strange about this underground river?" I looked up at Yun Chu and asked him in a low voice, while asking, I turned my head to look at Chen Yuqing and Lan Tianfang who were meditating and pranayama on the other end, and seeing that the two of them were not moving at all with their eyes closed, I then asked, "You just now, why didn't you make a move at the beginning?" ”

I lowered my voice and said closer to Yun Chu's ear: "Why did the two of them fight several times before you made a move?" “

Yun Chu turned his head and looked at me for a long time, for a second, two seconds, I suddenly came back to my senses: "Could it be that you did it on purpose?" Not a miscalculation? “

He smiled and blew into my ear, and said in a playful voice: "Who said it, I definitely didn't mean it, I really miscalculated." “

The devil believes it! My heartbeat suddenly accelerated and I almost didn't scream, and looked at him with a red face: "You have been with Chen Yuqing for a long time, and you have become annoying." “

"I'm not deaf, you still say it so loudly in front of me," Chen Yuqing opened his eyes and couldn't wait to flash over.

He looked at Yun Chu and stopped talking, and endured it for a while before he held back a sentence: "Young master, Fang Cai, did you really mean it?" “

The tone sounded weak.

"You are not deaf, I answered Xiao Ling'er in front of you," Yun Chu looked at Chen Yuqing's pig-liver-like face and said with satisfaction, "Say it again, I didn't mean it, it was an accident." “

Yun Chu raised his hand to brush the dust off the rock wall behind him, leaned in gently, and changed his words to the top of the underground dark river: "The person you brought here, went out for a while, right?" After a while, when he comes back from his exploration, I am afraid that there will be some new discoveries. “

"What discovery?" For a moment, Chen Yuqing's expression was a little stunned and said, "Young master, Ah Si is just going to explore the way." “

Chen Yuqing's expression changed, he thought of something, clenched his fists and asked, "Could it be that the thing that the Nine Princes are looking for is near this dark river?" “

Yun Chu didn't answer any questions, and looked at him calmly: "Don't you be curious, why do I have to break the stone wall and come here?" “

Chen Yuqing's face was stunned, his expression was slightly gloomy, and he listened to Yun Chu's words very intently.

"I'm coming here, naturally because this road is the right way to take us to where we want to go," Yun Chu said leisurely, "Otherwise, how can I be willing to spend effort to calculate." “

"Young master, you," Chen Yuqing's face blushed, his face tightened, paused, and said in a deep voice, "At the beginning, all the roads we walked in the underground passage were in vain, you knew from the beginning that this underground river was strange, why didn't you let us break it before?" “

Yun Chu frowned, looked up at Chen Yuqing strangely, and smiled freely.

He said in a calm tone: "I'm not an immortal, and the probability of such a thing as an unpredictable prophet is not high. I think one of the two roads must be right, since the easy road is in front of you, it is natural to go and see first, if it doesn't work, come back and try another way, it takes more effort, isn't it logical? “

"Someone," I shuddered all over, interrupted their conversation for a moment, and listened quietly, "It seems that Ah Si, who is exploring the way, has returned." “

"Well, Xiao Ling'er, your ear has improved." Yun Chu nodded and smiled.

It was really Ah Si who came, and while we were resting, he had already explored the way along the direction of the dark river.

According to his description, the dark river we see so far, this section is the narrowest, whether it is a river channel, or along the bank of the water, after turning the corner, the terrain is obviously more open than here, but this dark river meanders, Ah Si walked for a while and found that it was a bend and a bend, and there were scattered caves along the river bank, the terrain was very complicated, he didn't dare to explore it again for fear of getting lost, or rushed back to report first.

"What's next?" Lan Tianfang, who had finished pranayama, opened his eyes and asked loudly.

He woke up the Ninth Princess and walked over together, once again forming a small circle with Yun Chu as the center.

Tianfang cast an inquiring look, Yun Chu lazily got up and took a step forward, and pointed to Ah Si, who was silently on the side: "Just follow the road he explored." “

Walking along the bank of the underground river, the mud is slippery, the passage does not see sunlight all year round, and there are some unknown plants that cannot be named, and I really admire the tenacious vitality of these plants.

Yun Chu was still the same as when he came, holding a torch in one hand, but firmly grasping my arm with the other, he was much taller than me, and after walking for a while, I felt that my arm was sore and awkward.

Yun Chu looked at me sideways, and before letting go, he whispered, "You must follow closely, don't lose it." ”
