In the valley, fairy fog lingered, and a stream tinkled.

At the center of the valley, a giant ancient tomb shone in all directions. Numerous pure white snow lotuses grew around the tomb. Multicolored lights flowed like gentle waves, and they looked like dense clouds and colored glass. The instant Ou Yangming saw them, he felt like countless mysterious great paths were swirling in his mind. Nonetheless, after sensing them carefully, the feeling disappeared as if it was an illusion. At the top of the great tomb stood a crystal coffin. It was as heavy as a mountain and gorgeous. It gathered the beauty of the entire Spiritual Realm. The lid of the coffin was tightly shut, and the inside was shrouded in fog. It was like a mysterious starry sky that could not be seen clearly.

Behind the coffin was a bronze coffin. It was stained with fresh blood, and it was something that had been left behind since ancient times.

Even so, it was still bright red, and it was even emitting steam.

All of a sudden, 3 long arcs from the horizon broke the silence.

"Brother Yu, are you okay?" He Jian's face was full of worry.

"I'm fine! I used too much mental power." Ou Yangming's face was pale, and every pore on his forehead was covered with fine and dense beads of sweat. He smiled weakly.

"Let me block it for a while!" Before He Jian finished, he growled in a low voice, "3 swords with green lights flying like phoenixes!"

As soon as the word "flying" was uttered, the sword case shook, and the lid flew over. The Meridian Sword, the Chronicle, and the Blood Helianthus—the 3 famous swords rang at the same time and abruptly slashed forward. The sword-lights condensed together and transformed into a 20-meters-tall phoenix. With a proud roar, He Jian pounced forward. Without using the Heaven-lifting, he was still much stronger than an ordinary top-grade Spiritualist.

The Bone Dragon was clearly stunned for a moment, then its grey eyes turned red.

Looking at the phoenix formed by the sword-lights, a monstrous hatred emerged from its bone marrow.

This hatred had been carved into its soul. Even if its body dried up, and its soul died, it could not be erased.

It stopped chasing after Ou Yangming and He Jian. Instead, it directly pounced on the projection from the sword-lights.

Ou Yangming glanced at He Jian and noted softly, "Take this opportunity to leave quickly. The dragon's dead, but its strength is still that of a top-grade Spiritualist. Even if we join forces, we still won't have the strength to fight." This was both true and false. While the Bone Dragon was mighty, if the young fellow used all his trump cards, both sides would suffer heavy injuries. If his strategy was right, there would be a 30% chance of killing it.

"Yes, its physical body is too strong. Every strike carries an earth-shattering power." He Jian nodded. He felt his eyelids twitching wildly.

Especially when he saw the words on the dragon horn, his heart was filled with fear. What kind of person would be able to carve words on a dragon horn?

There was only one thing that he thought. Overbearing—incredibly overbearing.

Without warning, a gentle ray of light appeared in front of their eyes. The sounds of cicadas were also heard as if they could melt away all the desires, greed, viciousness, and even the emotions in their hearts, leaving behind only the purest and most beautiful. This was the core area of the valley.

At this moment, a deafening roar spread out.

It was the Bone Dragon. The anger in its voice had reached its peak. When one heard it, one would undoubtedly choose to self-destruct and destroy everything.

"Let's go, let's go!" At this time, Ou Yangming felt a chill run down his spine, and every hair on his body stood on end.

As they closed in on the tomb, the Bone Dragon went even crazier. Black flames burned around its body, and its eyes looked as if they were about to bleed. That was its shrine, and no one was allowed to tarnish it.

Every pattern on its bones began to light up, and an aura that could stir up the void appeared in an instant.

Ou Yangming gritted his teeth and once again entered the connection between Heaven and man. There was neither joy nor sorrow, and there was no matters and self. He said in a low voice, "Senior He, you go first while I hold it off. I'll use the Blood Flight to catch up."

"Be careful!" He Jian looked at him deeply then turned into a sword light and disappeared into the distance.

Ou Yangming took a step forward, and a vicious look flashed in his eyes.

His interspatial bag suddenly lit up. When the light was gone, he was already holding the Blood Spear Dragon Slayer tightly. He lightly pinched his fingers, and the red tassel surged like blood.

He shouted in a low voice, "Magic Art Amplification!" The light on the Dragon Slayer grew more intense.

"Stone Awl Art!" Before Ou Yangming's voice was gone, he coldly shouted again, and an imposing aura that was as heavy as a mountain burst out from his body. At this point, he seemed to have turned into a humongous mountain that suppressed the archaic era. With him as the core, the ground within tens of meters began to tremble. Stone awls shot up into the sky one after another, but they did not choose to attack. Instead, they used their strengths to defend. 1, 2... 1,000... Numerous stone awls piled up, transforming into an impassable stone wall that blocked the Bone Dragon's path.

In addition, more stone awls piled up, causing the wall to become thicker.

"Roar!" The Bone Dragon's body coiled up, and a drop of blood dripped from its eyes, causing half of the sky to turn red.

With a flick of its tail, a ripple appeared in the air due to the extreme force. It was clear just how mighty this force was.

An explosion was heard and the stone wall, which was tens of meters tall, collapsed. Dust filled the air.

It was then a giant head pulled the dust apart. Its eyes were black and red, and it bit down on the Bone Dragon.

The Bone Dragon paused for a moment. Its blood-red eyes dimmed then turned grey. An indescribable look of panic flashed in its eyes. The head bit down on its neck and with a cracking sound, it broke into two. Its enormous body fell from the sky, then it fell to the ground and struggled for a while before it lost its breath.

This was Ou Yangming's strategy. He would use the Stone Awl Art to lure the enemy then let the head bite it down and deliver a fatal blow.

Up until this point, Ou Yangming had not seen anything that could not be bitten or swallowed by the head. Despite that, faced with this Bone Dragon, he still had some doubts.

Now that he saw the head bite into the Bone Dragon's neck, his eyes revealed a look of surprise. He thought to himself, 'The head is still the best.' He had originally hoped that the head would block the attack, but he did not expect it to directly bite the Bone Dragon to its death.

Before this thought faded away, a sudden change occurred. The words on the Bone Dragon's horn came to life in an instant. Shone by the light from the sky, the broken bone on its neck quickly healed, and a grey light appeared in its eyes again.

"What... What's going on?" Ou Yangming was struck dumb. With a wave of his sleeve, he retracted the head.

The blood-red light on his waist flashed, and he shot out in a perfect arc.

Since he was moving too fast, the air in front of him was rapidly compressed and exploded in patches.

Nevertheless, Ou Yangming was already different as he had become an Advanced Spiritualist and understood the feeling of heaven and earth. When he used the Blood Flight again, he did not feel the slightest bit of discomfort.

He caught up to He Jian in an instant, and his speed did not decrease as he rushed into the big tomb.

Ou Yangming shook his head and looked around. A big tomb came into view. It was carved out of soft jade. It was exquisite and beautiful, covering an area of 3 kilometers. Looking down from above, many quiet paths spread out in all directions and carried a vague connection. They faintly contained 8 trigrams of Yin and Yang, as well as the divination of the great path. At the center of all the intersecting lines of symbols was a coffin carved out of an Extreme Grade spirit ore. It was exuding boundless spiritual Qi.

As long as one took a breath, an indescribable sense of comfort would grow from one's dantian.

The strangest thing was the words carved on the coffin. They were very complex and dazzling.

Each word had the effect of crushing a mountain and suppressing it for all eternity.

Behind the coffin stood a bronze coffin. It was only 1 meter long. The marks on it were mottled and stained with blood. It had been such a long time, but the words were still bright red.

Ou Yangming had never seen this bronze coffin before but at this moment, the name of this coffin appeared in his mind—the Upper Tribulations' Coffin.

"The Upper Tribulations!" One after another, mournful roars exploded in Ou Yangming's mind. Many ferocious faces appeared. They looked like they were not resigned to what had happened, and their faces showed hysterical hatred. Even if the hatred had existed for tens of thousands of years, it was not going to dissipate. This hatred could exist for all eternity until the world perished.

It was worth noting that the Upper Tribulations used the universe's origin power to cultivate. They were not tolerated by the universe, thus the 9 heavens and 10 disasters were sent down.

However, this race did not want to disappear. They used their physical bodies to withstand the disasters. They gathered their powers and used their blood essences to form the Upper Tribulations' Coffin. If the coffin was not destroyed, the race would not be exterminated.

Just as Ou Yangming was about to open the coffin, He Jian turned into a sword-light and descended.

The Bone Dragon let out a muffled roar and stirred the wind and clouds and shuttled through them. The blood light in its eyes was bright, but it was still hundreds of meters away from the big tomb and dared not cross the line. This big tomb was where it guarded, but there were also restrictions and shackles that stopped its approach.

He Jian looked around then retracted his gaze and asked softly, "Brother Yu, where's this place?"

Ou Yangming shook his head and answered, "I don't know, but we must be careful. This is the core area of the valley, so it's definitely not simple."

As he spoke, he stepped on soft jade and walked toward the large and small coffins. He did not care about the consumption of his mental power and entered the state of the communication between Heaven and man.

With every step he took, he began to analyze the situation in his spiritual world. He had a feeling that if he was not careful, the whole valley would self-destruct, and this space would be destroyed along with the river of time, leaving no trace behind.

It took him a full hour to cover the distance of over 166 meters, and his clothes were already drenched in a cold sweat.

This feeling of being in danger every moment was driving him crazy.

Finally, he was just a step away from reaching the top of the tomb.

He Jian followed behind him without saying a word. Even the hair on the top of his head stood up. His mind kept thudding as a sound kept bursting out in his mind. It was asking him to run as fast and as far as possible. The old man was used to big storms and waves and had a calm temperament, but he still had the urge to flee.

That being said, he wanted to rebuild his foundation. He wanted to take the leap to become a Venerable One. He wanted to stand on high ground and look down on all the mountains.

Therefore, he would not retreat—he would never retreat again...
