Sitting on a pile of profound beast corpses, Kaido was reflecting on the past months that he had spent on these endless plains.
"How many have I killed so far…?"
"998,679 profound beasts, Master."
Rias answered with her sweet voice, which washed the negative feelings away from Kaido's heart.
"Thank you for reminding me, Rias."
"No problem, Kaido-sama, I must help you~ I wanted to help you in other ways to relieve your boredom but the eyes of the Primordial Azure Dragon will spot me if I come out~"
"Never mind, it won't be too late to help me in your other ways after we get out of here…"
Kaido stood up when he noticed another wave of true dragons coming in his direction.
Thousands of dragons of various shapes and types, bearing the strength of the divine path, attacked in a single wave.
If this wave occurred in the outside world, it would have already been the apocalypse.
"Again, huh!?"
"Alright, let's complete the first million kills after this wave."
Kaido at the moment was frightening, frightening to the extreme, his body was drenched in blood from head to toe.
The mountain he was standing on was composed of thousands of corpses of dragons and profound beasts.
Two months had passed since he started the second stage of purification, and until now, he had barely managed to kill a million profound beasts.
All because he never stopped killing even for a single moment.
The last moment when he was resting on the mountain of corpses was a rare exception as he got a few breaths of relief.
He didn't know if it was due to the extreme difficulty of the trial or for some other reason, but the beasts seemed to come to him in waves without interruption!
If anyone other than Kaido had gone through this trial, he would have died a long time ago.
Kaido took out his bloody kanabo from the corpse of a certain dragon he standing on it at the moment, and charged up like an arrow shot from a bow towards the wave of true dragons that was about to engulf him.
ROAAAR!!!
ROAR!!!
Numerous dragon roars were heard on the horizon, and Kaido was swept away by various dragon breaths from the various profound elements.
Kaido's body passed through the wind dragon's breath which caused many wounds which ripped on his body but that didn't even make him blink.
He extended his hand backward and threw the kanabo with all his might.
Kaido's bat launched like an intercontinental missile, slashing through the head of the colossal Wind Dragon and ripping a huge hole in it before coming out from the other side.
The Wind Dragon let out a calamitous roar before its massive body fell to the ground with a loud bang.
The kanabo automatically turned back into Kaido's hand after taking down two other dragons that were following behind that wind dragon.
Kaido transformed into his hybrid form before exploding with ridiculous power and sliding through a wave of beasts that attacked him with various attacks, wanting to tear him to death.
In his hybrid form, he looked like a small fly in front of the colossal bodies of dragons. But this form allowed him to kill more efficiently.
It was much more flexible than the dragon form which had its benefits as well.
"Worororo!!!"
No doubt, Kaido enjoyed killing in this trial ground that allowed him to kill to his heart's content.
Each time he fell on the head of a certain dragon it would blast it into a bloody mess before moving on toward the next victim.
The dragons' corpses started to fall from the sky like rain, but that didn't scare the rest of the dragons instead caused them to go into a frenzied state that Kaido had become accustomed to in those two months.
Their eyes turned red and their profound energy began to burn as their strength rose exponentially, just like the Heretic God's method of energy leveling through gates.
But the difference between this and that is that these dragons burn their profound energy to sacrifice everything in order to drag Kaido with them to death.
"It's dangerous this time… Worororo!!"
From among the frenzied crowd emerged a gigantic black dragon with six intertwined horns, four wings, and an imposing, intimidating aura.
This dragon was an overlord-level beast at the peak of the Divine Soul Realm!
The Black Dragon opened its mouth and tried to swallow Kaido!
At this point, Kaido started to transform into his gigantic primordial phoenix dragon form.
An indulgence here means certain death!
…
"HAA… HAA… Rias…"
"How much is left!?"
"You have killed 1,809,567 Master. 190,433 left!!"
"This difficult trial is about to end… Persevere up, Master!!"
Kaido was leaning on his kanabo while standing on the corpse of a huge black dragon, five times larger than the black dragon he had killed three months earlier!
The reason he succeeded in killing such an impossible amount of beasts in the first place was that he had burned waves of hundreds of thousands of beasts at once with his scorching white flames every time they attacked him in waves.
The reason he had been attacked by waves was that the aura of the Primordial Azure Dragon pulsating from his body vaguely affected the trial space and made the beasts know his exact location.
Fortunately (or unluckily) he never had to search for profound beasts because they would find him!
But everything in this world has limits.
Even the cheater Kaido!
A long time ago, his profound energy was completely exhausted!
His physical strength was about to run out, too.
He could no longer find the power to transform and use his Devil Fruit abilities!
Five months and twenty days of fighting and killing almost drained him.
"… There are still 190,433… Right, Rias?!"
"Yes, Kaido-sama!"
"So maybe this wave is the last…"
Kaido's body swayed and he fell to his knee... Probably completely drained at this point.
"Kaido-sama!!"
Profound beasts and many powerful True Dragons were gathering around Kaido in a circle.
The profound beasts started climbing the mountains of corpses to reach Kaido who was nearly dying from exhaustion.
The endless green plains turned into black plains as a result of the enormous amount of dried beast blood.
"I will help you!"
Without waiting for her master's words, Rias started to move.
The scarlet pearl on Kaido's palm started to glow.
The scarlet glow spread to his hand and then his whole body.
Kaido's body which was completely exhausted started to regain some vitality.
"Thank you, Rias."
Kaido stood up again and charged up toward the final wave with endless killing intent.
...
The scene in front of Kaido's eyes suddenly distorted as the roaring voices of dragons and the miserable cries of profound beasts rang out from his ears. The place became quiet... The sea of blood that had just been soaked in its midst also disappeared as he entered a completely dark world.
Above this dark world, a pair of large blue eyes slowly opened.
The eyes of the Primordial Azure Dragon God.
"Congratulations on passing the impossible trial in time. You have successfully exterminated two million profound beasts in 5 months and 25 days. 5 days away from the scheduled time for the second stage. Your performance in this trial has rendered me completely speechless."
"You are truly a member of my clan, a worthy heir to my complete legacy and to revive the Primordial Azure Dragon Race in this world again."
