As their strength gets stronger and stronger, the distance that can be explored is getting farther and farther, and it is not a problem to advance 100,000 meters at a time, and there are about three to four karst caves within a distance of 100,000 meters。

Now the speed of exploration is fast, the more energy absorbed, the farther the distance to explore, from 100,000 meters to 150,000 meters, to 200,000 miles, and then to 300,000 meters.

With their current strength, they can already directly fight against the undercurrent.

In order to speed up the speed of exploration, Wu Hao no longer inserted spars on the rock wall according to the original method, groping forward, but directly pulled Ling Fei'er into the undercurrent, and led them forward by the undercurrent, and when the body was about to reach the limit, he would break away from the undercurrent and find a cave to rest for a while, and after adjusting his physical state, he re-entered the undercurrent, and let the undercurrent lead them forward quickly.

There is no day or night, no time, only endless darkness and icy water.

"Brother Linghao, when will we be able to leave here?"

Ling Fei'er hugged Wu Hao tightly, and the two of them quickly advanced along the undercurrent, plus they used their own strength as a propulsion, and they were like fish in the undercurrent.

"There must be an end to the undercurrent, otherwise he wouldn't have flowed all the time, we've been walking for so long, I think it should be soon. Wu Hao encouraged.

From the first day they entered the underwater passage, in terms of the distance they explored, they had already advanced at least a few hundred kilometers, and the diameter of this passage was about ten kilometers, which should be about the same, and it was almost the end, right?

"How long have we been here?" Ling Fei'er asked, actually just doing nothing, looking for something to talk about.

"How do I know, this dark place has no concept of time at all, I think most of our time is spent absorbing hedrons, I guess at least half a year. ”

"How do I feel like it's been more than ten or twenty years?"

"It's also possible, it's really been more than ten or twenty years?" Wu Hao smiled.

"Wow, then the two of us have been alone for more than ten or twenty years? The little girl grinned.

"It's been so long, can't you think of something else?" Wu Hao was helpless.

"What do you want me to think? I want to give it to you, but you don't want it. ”

"Okay, okay, I won't tell you, there seems to be another cave in front of you, do you want to take a break?" Wu Hao looked ahead, and at the end of the darkness, there seemed to be a little white light.

"Okay, we seem to have been in the undercurrent for a long time, just stop and absorb some strength to replenish our bodies, but our fish seem to be almost finished, right?"

"Just catch some after eating, there are quite a lot of fish in the undercurrent. "With enough strength, some things that were difficult now seem to be easy, and it is easy to catch a fish.

"Next, catch some delicious fish, I'm really tired of eating it. Ling Fei'er said.

"In this case, you still have to choose, eat whatever fish you can catch, or you will be hungry. Wu Hao smiled and sped up towards the little white light at the end of the darkness.

Soon his brow furrowed.

White light?

They had traveled at least a few hundred kilometers in the cave, and there were only two kinds of caves they encountered, either a cave made of ice and rock, or a cave made of hot stones, one with blue light, the other with red light, and the first time they saw white light.

"Is it ......?"

In confusion, Wu Hao's expression gradually revealed excitement, is that the end?

"Girl, speed up, we may have reached the exit. Wu Hao said excitedly, he had already picked up his speed.

Ling Fei'er was stunned for a moment, only then did she realize that the little light in front of them was white, not red or blue, and it was really possible that it had come to an end, and she quickly accelerated her advance speed in her excitement.

The light in front of me is getting stronger and stronger, and the excitement of the two people is getting stronger and stronger, this is definitely the light of the exit, absolutely!

Normally the caves were on the rock walls of the passages, but this powerful light was directly in front of them, and the magnitude of the light was greater than any cave they had ever seen.

The two men continued to pick up speed, moving in a straight line through the water like a torpedo, the light getting stronger and stronger, and the sound getting louder and louder.

It was like the sound of a giant waterfall.

"Wow~"

Like a torpedo breaking the water, the two people rushed out of the white light with a bang, and the water around them disappeared immediately, and the bodies of the two people fell freely, and the wind howled around them.

"Damn, it's finally out!" Wu Hao roared excitedly, hugging Ling Fei'er and stabilizing her figure in the air.

"Hahahaha, Brother Linghao, we're out, we're out, we're finally out. Ling Fei'er was even more excited, hugging him and jumping wildly.

Light replaced darkness, everything in front of me was so beautiful, the dense forest in front of me, the endless sea in the back, the blue sky, the white clouds, and the bright sun in the sky, as if from hell to earth.

"It's finally out!" Wu Hao also hugged Ling Fei'er tightly, at this moment his excitement was beyond words, hugged the little girl, and kissed her directly, Ling Fei'er was stunned, how could she be shy at this moment?

escaped death and saw the light of day again, and only a kiss could eliminate the incomparable excitement in my heart.

Maybe it's been too long under the water, and it takes a huge amount of time to do everything, and now this kiss is also long, maybe half an hour, maybe an hour, and the two people can't breathe anymore, and they finally separate.

"Brother Linghao, I love you!!" Ling Fei'er hugged him and shouted excitedly.

Wu Hao smiled without saying a word, and gently pinched her little face.

After such a long time, he actually likes this little girl very much, if he didn't have to restrain himself, he would have asked for this little girl as early as the underwater passage.
