The waterway is narrow and winding, and the further down it goes, the darker it becomes.

At first, Lin Jiu could still see the flow of water in the waterway through the fluorescence on the Langxuan Treasure Tree, but when he got to the bottom, he released his divine sense, and he could only vaguely see the four walls of the waterway.

After he had completely entered the other end of the waterway, it was pitch black in front of his eyes, and even in his consciousness, there was nothing to be seen at all.

And around him, there is a strong current of water, which makes him feel like he will be swept away by the current at any time.

Lin Jiu took a breath and stood firm, urging his mana to light up a ball of light, and then he had time to look at the scene around him.

Under the light, the darkness under the ground quickly receded in all directions, and the aimless fish and shrimp in the dark river also noticed something and gathered towards the place where the light was.

Inside the water, some algae moss reflects the light, which also emits a faint fluorescence.

Right next to Lin Jiu, another gap blocked by a boulder, the two little demons who were digging the passage together were hiding behind the gap at the moment and shivering—before the gap, there was a big fish the size of two zhang and a mouth full of sharp teeth that could not be named, and it was constantly ramming into the boulder, wanting to rush into the gap.

This big fish is the overlord of this section of the river basin at a glance, vicious and abnormal, and is shocked by the fierce qi on its body, and several little demons have forgotten about the fact that they can still cast spells for a while.

Seeing this situation, Lin Jiu couldn't help but shake his head, and pinched a seal and flicked it on the head of the big fish, and the big fish immediately became in a trance, flicked its tail, and swam in the other direction.

"Not bad, not bad." Feeling the environment of this underground dark river, the more Lin Jiu looked, the more satisfied he felt.

This underground river has its own mysteries, and it has a great suppression of the cultivator's divine consciousness, if it really comes to the last resort, the people of the Bibo Dragon Palace look at the underground dark river and hide, and they can escape without a trace along the direction of this underground dark river in an instant, no matter who comes, they can't find a trace.

"The only concern is whether there are any other dangers in this underground river." Lin Jiu sank his spirit.

The water flow in this underground dark river is cold and abnormal, Rao is him, as a great demon who has achieved the original god, his body is full of qi and blood, and he has been in this underground dark river for a long time, and there is a faint feeling that he can't stand it.

"This underground river is not a place for long." Lin Jiu took the waterway as the center and explored upstream and downstream for more than an hour before returning to the Bibo Dragon Palace.

There is not necessarily any danger in the underground river.

Aside from the chilling cold, the only thing worth worrying about was that there was some faint darkness wriggling in the depths of the underground river.

The light that Lin Jiu used his mana to induce was immediately swallowed by the darkness as soon as it touched it.

The most terrifying thing was that when Lin Jiu's attention was focused on the darkness for a long time, there were endless wails that followed his gaze all the way up, manifesting a scene of a mountain of corpses and a sea of blood in front of his eyes.

Looking at the underground dark river, Lin Jiu suddenly understood why it was safer underground than on the ground, and few monsters would choose to hide their caves underground—thinking that in addition to this underground dark river, under the earth, once it exceeded a certain depth, there would also be this terrifying darkness.

As for what these dark things were, Lin Jiu also had a faint guess.

Heaven and earth change, vicissitudes of life - since the beginning of the world, there have been endless wars between heaven and earth, and in that war after war, the demons, immortals, gods and Buddhas who died in the war can be described as countless.

The darkness under the ground is mostly the unwillingness or resentment left behind by those fallen demon fairies and gods.

It's fine to have some contact with them once in a while, but if a practitioner is in the company of these things for a long time, he will inevitably be infected by these things, and eventually become not demons, ghosts, and even more so, he will not be able to maintain his own consciousness.

……

"Running around, do you have anything else?" After returning to Yuanhuating, Lin Jiu first rewarded a elixir to a few little demons who were digging the passage, and then set his eyes on the rushing Erba.

Since Lin Jiu came back, Ben Bo Erba has always looked thoughtful and stopped.

An ugly and ugly-looking fish demon makes such a gesture, which is really funny, and it is really unbearable to look at directly.

"Shaojun, when we were digging the passage, I always felt that the water veins outside the Dragon Palace were a little turbulent." Ben Bo'er scratched his head and said very uncertainly, his eyes full of confusion.

"The water veins are in turmoil?" Lin Jiu's gaze froze.

Although Ben Bo Erba's cultivation is insufficient, his bloodline has its own abnormality, and he can feel the direction of the water vein, which is why Lin Jiu has to bring Ben Bo Erba with him whether he is surveying the water veins or digging a way out.

"You may feel that the turmoil of the water veins is coming from the inside or from the outside?" Lin Jiu asked.

"It's like it's inside, and it's like it's outside." In the eyes of the rushing children, he became more and more confused, and he had no confidence in his words at all.

"Inside...... Outside......" Lin Jiu groaned for a moment, turned around and took out the water vein map he had surveyed earlier from behind, and handed the water vein map to the front of Ben Bo Erba.

"We're here." Lin Jiu first pointed out the location of the Dragon Palace to Ben Bo'erba, "Tell me, the turbulence of the water veins you sensed came from those directions. ”

Bibo Dragon Palace is located at the intersection of several water veins, if there is any change in the water veins, it will inevitably affect the environment in the Bibo Dragon Palace, and then affect the changes in the Heaven and Earth Yuan Qi of Bibo Dragon Palace - in normal times, Lin Jiu naturally doesn't have to care about these things, but at this time, the Ten Thousand Saints Dragon King is in retreat in the depths of the Dragon Palace, in order to break the gap and achieve spiritual response.

If there was a turmoil in the Heaven and Earth Yuan Qi in the Dragon Palace at this time, it would inevitably affect the Ten Thousand Saints Dragon King who was still in retreat, so in this matter, Lin Jiu would rather believe it.

"This way...... This way...... There is also this ...... "Ben Bo Erba took over the water vein map, and after a long time, he stretched out his finger and dotted in several directions of the water vein map.

——These directions are completely different from the retreats that Lin Jiu has prepared.

If there is a change in the water veins, it is absolutely impossible to be the impact caused by those little demons breaking ground.

"Could it be that those bald donkeys from the Golden Light Temple are doing some small actions?" Lin Jiu raised his eyebrows, and went straight to Yuan Huating and headed towards the palace of the Ten Thousand Saints Dragon Mother.
