The heavenly tribulation struck down the enemies and the charging domain soldiers began fiercely surrounding the cultivators and attacking them. Dozens of soldiers would be massacred but several cultivators would die as well. In the very back at the top of the grasslands, Arthur stood there and stared at the sky. His eyes glittered with enlightenment even as lighting began descending towards him.
It struck his body and charred it, but he wasn't fazed since most of it was blocked by his armor. His aura continued to soar as the area around him began disintegrating into dust. Arthur exited enlightenment and roared with excitement. He leaped upwards towards the lightning that entered and attempted to destroy his body.
Dozens of lighting bolts collided against his armor and entered his body, causing most of him to become charred black, but his eyes glittered and stayed clear with no change. He punched into the air and the tribulation clouds were pushed back somewhat.
The heaven's seemed to see this and fiercely roared in retaliation by sending hundreds of bolts larger than tree trunks. Arthur finally frowned a little but and pondered before reaching for his the hilt of his sword in the scabbard. A resolute look appeared on his face.
"Escape the Earth!" yelled Arthur as his aura turned explosive. The scabbard resonated with him.
As his drew it out, the world seemed to collapse around him and disintegrate. Everything seemed to be returning to their origins and back to chaotic energy. Space began shattering as the glimmer of the sword began to escape. The Qi turned violent like an ocean in a storm and the heaven's began to tremble. The dao domain itself trembled before retracting into his own body.
This was a move that he comprehended and embedded into his peak grade divine sword after it was completed by a divine blacksmith. Based on a volcano, the scabbard is the Earth and the sword is the energy within that wants to escape. Once it's released, hell breaks lose and the heavens tremble. Land is annihilated and the sun hides from the smoke.
This was enlightenment he had gained when the headmaster once showed a fight on an array disk that recorded two legendary cultivators fighting near a volcano that erupted. It could not be complete and was only a step away from becoming a Dao grade weapon that incorporates Dao. He had infused his own blood essence into the sword and thus it was linked and intimate towards him.
His dao linked with his swords as soon as it was complete, allowing it to cross the barrier which initiated a weapon tribulation that merged with his own.
The cultivators thought it was their chance to escape, but it quickly turned to naught. They had unknowingly moved a long distance away from their original location after the dao domain retreated, making them inside mountains.
The middle-aged man that was attempting to escape saw this and he nearly pissed his pants. He had never seen such an extreme tribulation in his life. It gave him even more reason to attempt to escape.
The violent tribulation destroyed all the mountains within it's domain and any lifeforms turned to dust. Most of the cultivators were killed and only a few managed to survive.
As he drew the sword, the lighting bolts collided against him and his sword, increasing the connection between them as if they would become one. His aura and the swords drastically increased as a huge void surrounded them as a result of him drawing his sword.
The space and chaotic energies were rapidly sucked away into the interior of his scabbard as if it was a black-hole. Even the lighting was sucked away. His aura reached the peak of initial Duke Divine realm and the heavenly laws began to fiercely reject him since the heavenly laws within the Immortal Realm only permit up to peak Divine realm.
Finally, the tsunami of energy within was sucked into the sword reached it's peak.
"KRAKATOA!" yelled Arthur as he fully pulled out the sword.
As if two stars collided, the area for hundreds of miles violently exploded. Space and void shattered as Qi combusted. The tribulation was completely blasted away and the heavenly forces were pushed back. Shock waves ripped trees out of the ground and sent mountains flying. Like a nuclear bomb, trees outside the explosion caught on fire and charred. The earth turned into a sea of lava with a huge crater left behind. Nobody managed to escape.
Time slowly passed by as the lava lake in the crater began to solidify.
Sitting at the bottom of the crater was a pale Arthur who's aura had greatly weakened. His sword was still in the air but it's shiny brilliance was still there. Ripples of Dao was emitted from it's body and tribulation energy coursed through it. Part of the tribulation was absorbed to temper the sword before being added to it's body, greatly increasing it's power.
A divine grade weapon will form a pseudo weapon spirit that can respond instinctively to certain things but it has no intelligence. A dao grade weapon forms a complete weapon spirit with intelligence that grows it's own wisdom over time and can cultivate. The requirement is that the creator has a complete dao and the materials used are high enough quality. Another way is if the owner reaches dao completion and has a blood link to the weapon.
Everyone's dao is different though, so once a person with a different dao uses it, the power and effectiveness will be drastically reduced; and changing the weapons dao is near impossible even in the upper realms.
Once a dao weapon is created, they will have a tribulation. Afterwards, the weapon will be able to grow over time with the owner and refine itself indefinitely as long as the owner can upgrade the materials in it's body.
But unfortunately, the lower realms don't permit Duke Divine cultivators and Dao graded weapons and will eject them out into the upper realms.
This is happening right now, as the heaven's domain surrounded him and a spatial passage opened in the heavens. With no way to resist, he was pulled inside before disappearing from the Immortal Realm.
