Chapter 6182

The underground world is dark and lightless, cold and damp.

Two figures flashed through the darkness, and finally landed on two huge raised rocks, one by one glowing stones were thrown from their hands, illuminating the surroundings.

"It seems that this place is the source of the dark river."

The light floated, reflecting the faces of the two.

It is Lin Bai and Tuoba Xin, the holy son of the barbarian sect, who are looking for the source of the underground river all the way.

In front of them, there was an incomparably huge water surface, like a huge underground sea. Both of them were using the magic eye pupil technique, but neither of them could see the boundary of this huge water surface.

There is no light source in the underground world, and it is surrounded by darkness. The waves in the underground sea are floating, and the sound of the water echoes in the darkness, but it is particularly eerie.

This place is exceptionally quiet, so quiet that it makes people feel hairy.

"This place really contains extremely pure aura and energy of earth veins!" Tuobaxin squatted down slightly, his palms lightly touching the ground, as if feeling the pulse of the land.

Lin Bai watched his every move curiously, "With all due respect, I found that as long as your feet landed, you have been absorbing the aura and veins of this land?"

Lin Bai used Shura's eyes to see the exercises in Tuobaxin's body. As long as his feet landed on the ground, a force would pour in from the soles of his feet, and then run through the eight extraordinary meridians.

This gave Lin Bai a very strange feeling, as if Tuobaxin only needed to touch the ground, and they could start practicing endlessly.

Tuobaxin smiled slightly, without explaining, "Everyone has their own secret, doesn't it?"

"For example... Lord Wolf didn't reveal all his secrets to everyone, did he?"

Tuobaxin mentioned Lin Bai's secret, as if to warn Lin Bai not to ask any more questions.

Lin Bai was also very sensible, so he didn't continue to ask, but looked at the huge underground sea in front of him, "This place should be the source of the dark river, and the nine-headed dragon snake you mentioned should be here."

"So what do we do next?"

"Is it to set a trap and lure them out?"

Lin Bai asked about Tuobaxin's next plan.

Tuobaxin smiled slightly, "Arranging traps has never been my strong point; I believe Brother Lin, who is a sword repairman, would not bother to use such clumsy hunting methods."

Lin Bai smiled, "Then what kind of methods is Brother Tuoba used to?"

Tuobaxin squeezed his fist, "I prefer direct confrontation."

Lin Bai smiled, and the demon sword appeared in his hand, "Coincidentally, I am too."

One clenched his fist and the other held a sword, looking at the underground sea in front of him.

"If that evil animal is here, we just need to paddle across the water, and he will come out by himself!" Tuobaxin said: "We treat him as prey, why doesn't he regard us as prey too?"

Lin Bai then said: "I'm going to the left, you are going to the right, don't be too far apart, keep within 10,000 meters, I can reach you at any time!"

Tuobaxin nodded and said: "Okay."

The two formulated a battle plan in a few words. Immediately, the two jumped up from the boulder, one went to the left, and the other to the right.

Holding the demon sword in his hand, Lin Bai pressed against the surface of the water, and walked forward slowly. At the same time, he also paid attention to Tuobaxin's actions. He kept a distance of 10,000 meters from Lin Bai, and also pressed against the surface of the water, walking forward cautiously .

In the underground sea at the source of the dark river, the water surface is exceptionally calm. Occasionally, there will be waves tumbling, making the sound of the water resounding everywhere. In this quiet and terrifying space, it strikes everyone's heart.

Crashing... When Lin Bai was walking forward, there was a sudden splash of water. Lin Bai immediately looked at it and saw a splash on the water not far from the front left.

Lin Bai looked carefully, but found that there was an unknown black fish in the water. After seeing Lin Bai, he panicked and went to the bottom of the water.

"Try not to go underwater." At this time, Tuobaxin's voice transmission reached Lin Bai's ears, and he added after speaking, "It's very dangerous!"

nonsense.

Can I know it's dangerous?

Lin Bai agreed with a smile. Since entering the underground river, Lin Bai has maintained his behavior on the surface of the water and never considered taking the risk of entering the water.

Because Lin Bai has investigated, whether it is an underground river or the source of this place, the distance from the water surface to the bottom of the water, no matter how short it is, is as deep as a hundred feet.

Moreover, there is no light under the water, even if Lin Bai has the magic eye pupil technique, he can't easily see through the darkness. Who knows what strange species are hidden in those underwater darkness?

Lin Bai and Tuobaxin were separated by thousands of miles, and they moved forward slowly, but they did not encounter any danger along the way, let alone the nine-headed dragon snake.

It turned out that Lin Bai found many unknown spirit fish in the water, including black ones, dragon ball spirit fish, and other fish... There are many types, but none of them are too aggressive.

"This underground sea is really big. I don't know if we've gone halfway." Lin Bai sent a voice transmission to Tuobaxin, analyzing the current situation.

"My Dharma Eye pupil technique can't see the boundary, Brother Tuoba, can your Dharma Eye pupil technique see the boundary?" Lin Bai asked curiously.

Tuobaxin replied via voice transmission: "Brother Lin's Shura Dharma Eye can't even see the boundary, and the Dharma Eye pupil technique I practiced can't see it even more."

Lin Bai was taken aback for a moment, Tuobaxin actually saw that Lin Bai was cultivating the Asura Dharma Eye?

"However..." Tuobaxin continued: "Although I can't see the boundary with my magic eye pupil technique, I can feel the boundary with another method."

"According to our current speed, we will be able to cross this underground sea in another seventy-two hours."

Tuobaxin didn't say exactly what method he used to measure the size of the underground sea, but he gave Lin Bai an approximate time.

Through this time and their speed, Lin Bai could easily calculate the width of this underground sea.

"How deep is it?" Lin Bai looked under the water.

Tuoba Xin was stunned for a moment, and also glanced under the water, "It's bottomless. That's why I told Brother Lin, don't venture into the water."

Tuobaxin didn't say it clearly, but Lin Bai was somewhat suspicious.

Since Tuobaxin can measure the width of this underground sea, he naturally has a way to measure the depth of the underground sea.

But he didn't tell Lin Bai explicitly, there is only one possibility, that is, he didn't want to tell Lin Bai.

Just when Lin Bai was thinking, Tuobaxin suddenly sent a voice transmission, and the voice became extremely urgent, "Brother Lin, be careful, something is coming up from the bottom of the water!"

"Going towards you!"

His words were simple and shocking, telling Lin Bai that something floated up from the bottom of the water and passed towards Lin Bai in a few words.

Lin Bai immediately lifted his spirits, and he also felt a danger coming from under the surface of the water, and rushed towards him at an extremely fast speed!

Lin Bai immediately stopped on the water surface, and the four flying swords immediately rushed out of his body and surrounded him, the monster sword in his hand was filled with a strong killing intent.

After Tuobaxin felt the danger, he also quickly approached Lin Bai.

Just in this split second!

With a loud bang, the surface of the water burst open, and accompanied by a sharp and ear-piercing howl, a huge monster rushed out from under the water and appeared in front of Lin Bai.

"Roar!" The deafening roar made Lin Bai's eardrums tingle.
