Chapter 198 The graffiti of our ancestors contains a lot of information
"Yun Shen, how long will it take!"
"It's almost there, my prince. Give me another ten breaths!" Yun Shen was sweating profusely, and his hands were so fast that afterimages almost appeared.
He used his own blood to quickly draw a reverse formation on the ground to break the formation!
"Hold on!"
Xiao Yu drew the sword from his waist, and with a flash of his body, he appeared at the weakest point of the formation like a ghost.
"puff!"
An almost invisible flash of a knife passed by.
The head of a giant rat, which was about to break through the defense line, shot up into the sky!
Hot black blood gushed out!
Xiao Yu and his sword were like an insurmountable barrier, firmly guarding the defense line!
All the giant rats that came within three feet of him were killed instantly without exception!
"alright!"
At this moment, Yun Shen let out a desperate cry!
He finished the last stroke and then spat out a mouthful of blood onto the center of the formation!
"break!"
Buzz——!
The entire stone chamber shook violently!
The blood-colored rune lights on the wall dimmed in an instant!
The giant rats that were attacking frantically suddenly froze in their movements, and a hint of confusion appeared in their blood-red eyes.
"Now! Kill!"
Xiao Yu gave an order!
The morale of the Black Armor Guards was greatly boosted, and the swords in their hands turned into a forest of swords, slashing madly at the giant rats that had temporarily lost their ferocity!
Without the blessing of the Blood Evil Formation, these giant rats are still thick-skinned and tough, but they are no longer invulnerable to swords and guns.
When the last giant rat fell, the entire stone chamber was covered with black blood and mutilated corpses.
The air was filled with the sickening smell of blood.
The Black Armor Guards were all panting and had bruises on their bodies, but no one was seriously injured.
"Clean up the battlefield and move on."
Xiao Yu sheathed his sword and glanced at the bronze coffin on the ground, his eyes as deep as the sea.
And from the depths of the darkness, a faint heartbeat sound began to reach his ears.
Boom... Boom...
Boom... Boom...
After passing through the stone chamber filled with blood and the smell of death, there is a long and depressing corridor ahead.
But this time, the corridor was too clean.
There is no evil moss, no soul-beating mushrooms, and no fearless mutant giant rats.
The faint "thumping" sound in the air, like the heartbeat of a giant beast, became clearer and heavier.
The team moved forward in deathly silence.
After walking for about another cup of tea, a vast dark golden halo appeared at the end of the corridor.
The moment they walked out of the corridor, even the Black Armor Guards, who had been through hundreds of battles and had minds as hard as steel, couldn't help but gasp in surprise.
"Oh my god..." Xuan San's eyes widened, his mouth wide open enough to fit an egg. "This... is this a place that could be built by humans?"
What appeared before them was a huge underground space that could not be described in words.
The dome is so high that you can't see the end of it, it's like an inverted night sky.
Countless unknown glowing crystals dotted it, like twinkling stars.
In the center of the space is an extremely large circular altar.
The altar was carved from a single piece of unknown black rock, covered with intricate and mysterious patterns, emitting an aura of pressure that was enough to make even the soul tremble.
The dark energy, so thick that it almost turned into substance, spread slowly around the altar like a black tide.
But what is strange is that within this extremely dark and evil aura, there is also a faint trace of pure aura.
The breath was very weak, but it was like a candle in the wind, stubbornly emitting its light and heat, adding a hint of imperceptible vitality to this space that should have been hopeless and dead.
"Your Highness..." Yun Shen's voice trembled slightly, and the compass needle in his hand pointed motionlessly at the center of the altar.
"The atmosphere here... is... too terrifying..."
"This is simply the lair of the Netherworld Qi!"
Xiao Yu didn't say anything.
His gaze had already passed everyone else and was fixed on the center of the huge altar.
There, there was a circular base that was obviously used to place something.
But now, the pedestal is empty.
Only a circle of deep indentations and some long-dried dark red marks proved that something extremely important had once been placed there.
"Xuan Yi," Xiao Yu said in a low voice, "Take your men to keep watch in the surrounding area. Report any unusual movements immediately."
"yes!"
"Yun Shen," he turned his head, "Come here and look at these walls."
Yun Shen then noticed that the walls of this huge space were covered with densely packed ancient murals.
Those murals have a simple and rough style, with simple and powerful lines, but they depict thrilling scenes vividly.
The two walked to the nearest wall.
Yun Shen raised the fire starter, leaned forward to take a look, and his pupils suddenly shrank!
"Your Highness! Look!" He pointed at a figure on the mural, wearing a tall hat and a wide belt, holding a whisk, and said excitedly, "This... this person is wearing the attire of our observatory's first imperial preceptor!"
Xiao Yu's gaze fell on another mighty man wearing dragon-patterned black armor and holding a long sword next to the first generation national teacher.
“This person…”
"The pattern on his armor is the golden dragon pattern used by the Lin royal family during the founding of the country."
Lin is the surname of the royal family of the Great Zhou Dynasty.
In other words, the person in the mural is his ancestor!
At the same time, huge waves were rising in the hearts of both of them!
They continued to look down.
The first mural depicts a war that was as devastating as the earth and sky.
The first generation of national master and the ancestor of the Lin family are joining forces to fight against an extremely huge black heart.
The heart hung suspended in mid-air, its every beat causing the mountains and rivers to change color and the earth to crack. Countless hideous, vengeful spirits roared and leaped from the heart, as if to drag the entire world into an endless hell.
“Heart of the Netherworld…” Yun Shen muttered to himself, “So, it… looks like this…”
The second mural depicts the first generation of the Imperial Master using his own blood and essence to create a gigantic formation covering the heavens and the earth, temporarily trapping the black heart within.
The Lin ancestor held a long sword in his hand, drawing on the power of the stars above the nine heavens, and merging it with the dragon energy of the Great Zhou's national destiny, transforming it into a sword of light that pierced through the heavens and the earth, and fiercely stabbed at the heart!
In the third mural, the heart was severely damaged, the light dimmed, and the size shrank countless times.
The first generation of the Imperial Master and the Lin family's ancestors took the opportunity to seal it into a black stone box, and then brought the stone box to this huge underground space and placed it in the center of the altar.
Seeing this, everything seems clear.
This is where the Heart of the Underworld was originally sealed.
However, the next mural made both of them frown.
The fourth mural depicts something very strange.
Even though it was sealed in the stone box, the Heart of the Underworld continued to emit evil aura, constantly eroding the seal and everything around it.
The first imperial teacher and the ancestors of the Lin family seemed helpless in doing anything about it.
Just when they were at a loss, something new suddenly appeared on the mural.
"What is this?" Xiao Yu asked, pointing at a glowing object on the mural that was held in the palms of two people's hands.
Yun Shen leaned in closer to examine it carefully, and the expression on his face became more and more strange.
"Your Highness... this... this painting is too abstract..."
