"Looking at the scene of the sky, the Acacia Bridge will be completely displayed in front of the world in less than five days. We only have five days left. ”

At this time, the eldest brother among the three frowned and spoke.

Listening to the words of the middle-aged, it seems that the three of them have only been here for a short time.

"yes, time is running out. Three more days passed, and we still haven't found a way out. I think our approach may not be right. The second child suddenly spoke.

"Incorrect? How so? The eldest and third were stunned.

"Big brother, we want to find a place where the underground undercurrent gathers, in fact, we don't need to be so troublesome, we just need to open a tunnel, dig through the underground undercurrent, and then rush in, and move forward with the underground undercurrent."

"Second child, what do you mean......" The eldest and third had a flash of light in their eyes at the same time, and then their hearts were crossed, "Now it's the only way to do it." Second, your cultivation is the highest, so when the time comes, you can take Elena down with you. ”

The second child nodded: "Don't worry, I will definitely protect her." The impact of this underground current may be great, but it can't hurt us. ”

"Well, then we'll go back and prepare. An hour later, the three of us and Elena set off from three underground currents at the same time, and if the four of us were able to meet in the end, it would prove that the meeting point was the place where the Double Dragon was formed, and that was the breakthrough. The boss thought for a while before speaking, "It shouldn't be a problem for everyone to open up the tunnel for an hour, right?" ”

"Well, no problem, more than enough time."

"Alright, let's go now."

The three of them got up and disappeared into the restaurant again.

Judging from the conversation between the three of them, it seems that they are about to enter an underground undercurrent.

"Go back and tell Yu Linfan."

……

"What? Have they already carried out the operation? In the inn, Yu Linfan listened to Zhang Yifeng's words, and suddenly exclaimed, "Then what are you waiting for, follow quickly." Which gate did they go to? There are people at the southwest and north gates, right? Then let's go to the West City Gate where their second child is, you said that his cultivation is the highest, I think I have a greater safety factor with him. ”

Zhang Yifeng frowned: "You really want to go?" ”

Yu Lin Fan didn't seem to take the matter of the underground undercurrent to heart. Yulin Fan's cultivation is not strong, but it is only the cultivation of the Bigu period.

"Go, why not! For hundreds of years, the Acacia Bridge did not appear. Since I have been met by my generation, how can I be willing not to fight for a chance. If you can climb the Acacia Bridge, it will be a lucky thing, and it will be passed down through the ages. ”

"Since you say so, let's go."

A few minutes later, Zhang Yifeng and the three of them left the water city.

"Brother Zhang Yifeng, where is he playing the tunnel?"

"I don't know, we'll just look around. The location should be remote. Let's just look for it in the middle of nowhere. ”

"Yes, yes, yes! Reasonable! ”

It took half an hour to search for the West City Gate, but the three of them did not find any tunnel entrances.

"Zhang Yifeng, are you sure they acted?" Yu Linfan's voice was a little anxious. It is indeed a painful thing to see a similar bridge, but not be able to go up. No wonder the predecessors said that similar bridges can only be seen, not touched. Is there really no one who can climb it?

"Convinced! It should be right ahead. You see here, there are footprints and strips of rags. He must have made a tunnel around here. Zhang Yifeng suddenly came to a grassy side.

When Yu Linfan heard this, he instantly refreshed: "Then hurry up and find it!" ”

Five minutes later, Yu Linfan's exclamation came: "Brother Zhang Yifeng, Yunyun, come here, here!" ”

Zhang Yifeng turned his head and saw that a one-person-sized cave appeared in a hidden corner, bottomless, and the entrance of the cave was very smooth, as if it had been cut out with a sword.

"It should be here. I'll go down first, and you'll go behind me. With that, Zhang Yifeng entered the cave first, followed by Yulin Fan Kuang Yunyun.

As we advanced, the sunlight did not shine at all, and the inside of the cave was pitch black. But the three of them are all cultivators, so it is not a problem to use aura lighting.

"Zhang Yifeng, can you go faster?" A quarter of an hour later, Yu Linfan looked very anxious, "Otherwise, I'll go ahead?" ”

"It's not a straight line, it's a serpentine curve. It is estimated that it is to cushion the impact of underground currents. If we go fast, we may meet the senior, and if we slow down, we will also let him solve the obstacles in the way for us. ”

When the words fell, Zhang Yifeng stopped saying nothing and concentrated on shuttling in the tunnel.

This tunnel was longer than he imagined, winding back, as if there was no end, he had been walking for twenty minutes, although the speed was not fast, but ordinary cultivators could not catch up.

I don't know how long I walked, Zhang Yifeng's pupils shrank suddenly, and said, "Stop, they're in front!" ”

Zhang Yifeng's keen perception has already caught that there are fluctuations ahead.

At this time, at the bottom of the tunnel, a middle-aged man turned his head and whispered: "Strange." ”

"What's wrong?" Next to the man, a woman muttered softly, her hair was as red as a maple leaf, her figure was tall, convex and backward, she was a rare stunner, no more than twenty-five or sixteen years old. This woman should be what they call Elena.

"Nothing, maybe a gopher got through the back." The middle-aged man smiled faintly and said, "You be careful, stand aside so as not to hurt you." ”

The sword in the man's hand was raised, and a circle of golden aura struck towards the opposite ground like a tornado. The hard ground was as easily torn to pieces by the sword qi as tofu, and the tunnel was being opened up quickly.

Zhang Yifeng stood in place, waited for five minutes, and only after making sure that the other party had left did he move on.

"Follow me, be careful."

The three of them walked all the way along the tunnel, and after twenty minutes of walking, Zhang Yifeng stopped again, and Yu Linfan accidentally bumped into his body.

"I said Zhang Yifeng, why did you stop again, and, please say hello before you stop!" Yu Linfan was a little speechless.

"It's not that I'm going to stop, it's that the other party is stopping."

"The other party stopped?" Yu Lin Fan was stunned for a moment, and then a flash of light flashed in his eyes, "You mean, he has found an underground undercurrent?" ”

"Most likely, the reason why he didn't break through the last wall was to wait for time, and he agreed with the other two to act together in an hour. Even if the three of them estimate each other's time from time to time, it won't be much worse. ”

"So what do we do?"

"Wait."

I don't know how long I waited, but just when Yu Linfan and Kuang Yunyun had the urge to doze off, there was a muffled sound from the tunnel at the bottom, like a muffled thunder, and the entire tunnel was shaking.

"What's going on?" Yu Lin Fan was excited, and his expression became serious.

Zhang Yifeng also frowned slightly, gathered the aura to his ears, listened carefully, and his face changed instantly: "Not good!" It's underground...... Stream ......"
