Your Chapter 4 draft already does a good job advancing Ye Chen's journey and introducing the Sage God's legacy. Here's a lightly edited version to improve clarity, grammar, and flow—while preserving your structure and
Seeing Gu Xuan effortlessly thrown out of the building proved just how powerful the presence within this ancient book was. A white light enveloped the entire structure as a glowing male figure slowly materialized in front of Ye Chen.
The figure observed Ye Chen closely. "Ancient Yang Body… Not bad," he muttered with mild interest.
"I am the Sage God, one of the Five True Gods of the ancient era. I left a fragment of my soul in this book to find a worthy successor.
Since you've unlocked the seal and awakened my legacy, you now have the right to inherit my power."
In the Divine Realm, even hearing the name "Sage God" would bring shock and awe
let alone the chance to inherit his power. Anyone else would have been ecstatic. But not Ye Chen.
"Senior, maybe you're mistaken. I only touched the book by accident," Ye Chen said nervously. A being strong enough to repel Gu Xuan could easily end his life if he chose to.
Sensing Ye Chen's unease, the Sage God smiled. "Do not worry. I mean you no harm. Let me explain."
"To activate this inheritance, one must not only possess this book but also a special key
and that key hangs from your neck."
Ye Chen instinctively looked down. The necklace his grandfather gave him was glowing with a fiery red light.
"What is this necklace exactly?" he asked.
"That is a Fire Crystal
one of the Eight Elemental Crystals. Fire, Water, Wind, Earth, Lightning, Light, Darkness, and Dimension. Each holds immense power and is scattered across the natural world. You already possess one."
"I don't have much time left. Prepare yourself to receive my inheritance." From his fingertip, a single drop of glowing blood formed.
"This drop of blood has been refined over millions of years. Once it fuses with your body, your veins and meridians will be reshaped in my image. It will be painful."
Without waiting for consent, the Sage God gently pushed the drop toward Ye Chen's chest. The blood seeped into his skin, spreading rapidly.
An unbearable pain followed.
It felt like his entire body was being torn apart, stabbed by thousands of invisible blades. Ye Chen screamed in agony as his veins burned from within.
Outside, Gu Xuan was frantically attacking the barrier around the building. He unleashed 80% of his power, but the barrier didn't budge.
Hearing Ye Chen's painful cries, Gu Xuan's heart clenched. "What's happening in there?!"
Left with no choice, Gu Xuan activated his ultimate technique. The entire planet trembled as vast energy condensed around him. He struck the barrier with all his might.
"BOOM!"
The resulting explosion echoed for hundreds of kilometers. The sky darkened, dust rained down, and trees bent under the pressure.
But when the dust settled... the barrier remained intact.
Gu Xuan could only sigh, powerless to intervene. "Please hold on, Ye Chen…"
Inside, the pain finally subsided after two grueling hours. Ye Chen collapsed, drenched in sweat, but alive. The Sage God's blood had fused successfully.
Ye Chen felt stronger
lighter. His mind was clearer than ever before.
"You've inherited a portion of my power," said the Sage God. "But to unlock my full legacy, you must find the remaining seven Elemental Crystals."
"Where should I search for them?" Ye Chen asked.
"That depends on your fate. They are scattered across the world
perhaps already in the hands of others."
"As for cultivation techniques, they're all inside this book. I entrust my unfinished mission to you."
The Sage God began to fade. "With power comes burden. Remember that. My time ends here."
"Wait! What mission?" Ye Chen called out, but the Sage God's soul vanished.
The book dissolved into a beam of light and entered Ye Chen's mind.
Suddenly, he was flooded with knowledge—cultivation techniques, battle arts, and divine secrets known only to the Sage God.
Among them was something extraordinary: the True God Body Technique. Divided into 10 tiers, each level would amplify the user's physical strength exponentially. But to reach the higher levels, the body would need intense, near-inhuman training.
Ye Chen also discovered something astonishing about his body. Normally, cultivators possess 52 deep veins. Ye Chen now had 60.
The eight additional veins corresponded to the eight elemental crystals. Right now, only the Flame Vein had been awakened due to the Fire Crystal.
Flame Vein – Special Ability:
Temporarily increases strength by several times. If used with insufficient cultivation, the backlash can severely injure the user.
The book now functioned like a system
displaying only information relevant to the currently awakened crystal. The rest remained locked until the corresponding elemental crystal was found.
Ye Chen now understood that his journey wouldn't just be about cultivation—it would be about unlocking each element and completing the Sage God's legacy.
Just then, the book gave him full access to techniques not bound to any specific element. He absorbed each one quickly.
After finishing his study, Ye Chen stood and moved toward the exit
but the barrier still blocked his way.
He frowned and thought about dispelling it. As if reading his intent, the barrier vanished.
A figure dashed inside instantly Gu Xuan.
"Young man!" Gu Xuan's eyes widened. "You're alive…"
Ye Chen gave a tired smile. "Barely."
