At this time, such scenes were being played out all over the prehistoric world.

Almost all black water appears in places where it originates.

For example, ponds, rivers, lakes, seas and other places.

…

Deep in the forest not far from Shanhai City, a quiet lake is shrouded in strange black water. The black water seems to have life, constantly spreading outward, eroding the surrounding land and trees.

"Chen Huai, come here quickly!" Suddenly, a shout broke the silence of the forest.

After hearing the shouts, the man known as 'Shen Huai' quickly rushed towards the Black Water Lake.

He was wearing a robe as white as snow, with a sword shining with cold light hanging from his waist. His skin was as white as snow, his facial features were as delicate as sculptures, and his face was as gorgeous as an immortal, especially his eyes which were as clear as water, but revealed a hint of coldness.

When he was about to reach the Black Water Lake, he swung his arm and quickly drew out the sword from his waist.

In an instant, a dazzling sword light flashed, as if tearing through the darkness.

Immediately afterwards, a raging flame erupted like a volcanic eruption, like a huge tongue of fire, sweeping straight towards the Black Water Lake!

There was only a loud bang.

boom!

The flames collided with the black water, making a sizzling sound, and the black water was continuously engulfed by the flaming blade.

"Set up the formation!" the young man in white said.

When the young man in blue clothes who was standing nearby heard this, he quickly put his hands together and muttered something.

In an instant, countless dazzling golden hexagram seals shot out from the hands of the young man in green like meteors, spinning rapidly in the air like flying flowers.

These golden hexagram seals seemed to have life. After flying in the air for a while, they landed around the Black Water Lake at an astonishing speed.

When they landed on the ground, they stood firmly in place like seeds rooted in the earth, emitting a faint light.

"Arm the formation, reach the sky, bring down the fire, and eliminate it!"

As the young man in green finished speaking, the originally still golden hexagram seals suddenly began to vibrate violently, making a buzzing sound.

Immediately afterwards, a raging fire suddenly broke out within the hexagram formation. The fire was so fierce that it was like a roaring beast, pouncing towards the black water with its fangs and claws bared.

Heishui seemed to feel the threat from the fire and began to struggle desperately.

It rolled and stirred within the hexagram formation, trying to break free from the restraints of the fire, but no matter how hard it tried, it could not escape the range of the hexagram formation.

At this time, the young man in white came to the shore of the lake with a sword in his hand.

His eyes were as cold as ice as he stared at the black water that was struggling in the hexagram formation.

Immediately, he raised his sword.

One cut!

The powerful fire-colored giant blade sank into the hexagram formation and quickly cut off the struggling black water!

Boom boom boom——

Flames shot up into the sky and a foul smell spread quickly.

As time went by, the black water in the lake gradually decreased.

Until it is completely erased.

The young man in white was Shen Huai. He narrowed his eyes slightly and said in a deep voice, "There are too many water sources like this in the prehistoric world. It's too slow for us to investigate and deal with them one by one. If we want to completely eliminate the black water, we have to find its root."

Having said that, he raised his eyes and looked at the young man in blue clothes, Qing Wu.

"Can you figure out where the black water originated?"

Upon hearing this, Qing Wu's handsome face paused slightly, and then he shook his head with a look of regret, "With my current strength, I can't calculate it at all."

Shen Huai's eyes dimmed slightly. He put the sword back into the scabbard and walked towards the lake.

At this time, there was no black water in the lake, let alone clean water.

It now looks like a huge corroded pit, which is shocking to see.

"Chen Huai, do you remember anything?" Qing Wu walked over and asked thoughtfully.

Shen Huai was stunned, and turned to look at Qing Wu with a puzzled look, "Remember what?"

Qingwu met his gaze, "Have you remembered the memories of each life?"

Shen Huai's brows furrowed slightly, and his expression became even more confused.

"Every life?" He repeated Qingwu's words. "I don't understand what you mean. What does every life mean?"

Qing Wu looked at Shen Huai's reaction and couldn't help but feel a strange feeling in his heart. He originally thought that Shen Huai would react to this question, and might even have remembered the memory of reversing time and space many times.

But now it seems that Shen Huai knows nothing about these things.

"It shouldn't be like this..." Qing Wu muttered to himself, his brows tightly furrowed.

Shen Huai noticed Qing Wu's strangeness and asked, "Did you calculate something?"

Qing Wu came back to his senses, his eyes met Shen Huai's, and their gazes met in the air.

Qingwu was silent for a moment, then said seriously, "I need to figure out what we should do next to help the greatest extent possible."

When Shen Huai heard this, the figure of Shen Yan appeared in his mind, and a trace of loneliness flashed in his eyes.

He hasn't seen his sister for a long time.

Ever since he separated from his sister, he has been traveling with Qingwu.

During this time, they handled a lot of black water.

But the black water came with such force that it was impossible to resist it.

I don’t know how my sister and the others are doing now?

Shen Huai pulled his thoughts back, lowered his eyes to look at Qingwu who was calculating, waited for a moment, and asked softly: "How is it?"

Qingwu stared at the hexagram intently, his pupils shrank slightly, and he couldn't help but clench his fingers.

How could it be...

Is it going to happen again? !

Shen Huai keenly caught Qing Wu's emotional changes. He frowned slightly and his eyes fell on the hexagram.

During these days, he had been with Qingwu and had naturally seen different hexagrams. Sometimes he would ask questions, and Qingwu would give him answers.

When his eyes fell upon the hexagram that looked like it was covered in blood, his heart sank. "Is this... a bad omen?"

"Who do you think you are?" Shen Huai shifted his gaze to Qing Wu.

Qing Wu pursed his lips. After silently putting away the divination tools, he looked up at Shen Huai and said in a difficult tone, "Our final outcome."

Shen Huai's brows furrowed even tighter.

"We? What do you mean?"

“…all living beings.”

Shen Huai's expression suddenly turned cold. He knew the accuracy of Qingwu's divination, but he was unwilling to believe it. He took a deep breath and asked, "Is there a solution?"

Qingwu lowered his eyes and remained silent.

This posture clearly answers: There is no solution.

Shen Huai suddenly thought of something, narrowed his eyes and asked: "Were you injured just now? Are you feeling unwell?"

Qingwu was a little stunned, then shook his head.

Shen Huai smiled when he saw this.

“There is a solution.”

This hexagram concerns all living things, so how could Qingwu figure it out so easily?

Moreover, Qingwu has not suffered any backlash.

This means that—

The secret is deceiving them!
