A torrent of flame passed through the Tear, burning every single Malice that tried to cross. They burned without leaving anything behind.
It was the first time Kai unleashed the full might of Phoenix fire, as there was nothing to stop him in the sky. But he was still pleasantly surprised by the power to burn anything with just a touch. Even the black shadow wasn't spared and turned into black smoke in less than a second.
Still, he felt the immediate effect. He could somehow feel Amber's Spirit Power reserve decrease slightly. It was just as Amber explained. When they were fused, Amber's Spirit Power would be used first to fuel the Phoenix fire and any technique Kai unleashed.
That was why he never felt tired, and the Phoenix girl needed to replenish her Spirit Power every time they fused. It didn't even cost 1% of her reserve, but it was still a big number nonetheless.
If put in numbers, he could only use a similar attack around 200 more times before Amber's Spirit Power depleted completely. Of course, that didn't count her natural Spirit Power recovery she did through breathing.
In a normal state, it wouldn't get depleted at all.
"This is crazy. They are coming nonstop!" Kai muttered to himself as he continued to burn the Malices. Some escaped but met their end by Shuten Douji's club on the ground.
Because he was high in the sky, he noticed the destruction caused by Amber's acquaintance had stopped, and two familiar red Onis ran toward their location from afar. They were Kirimaru and Ranga.
"Amber! How long does Tear usually form in one place?!" He asked the knowledgeable person, who he hoped would know the answer.
[It varies! Depending on the cause, it can go for 5 minutes to 30 minutes! If it naturally appears, then it might even go for as long as 1 hour!]
"Huh?! What do you mean naturally appear!"
A Malice jumped to him from the Tear, and he just swiped his arm to create a firewall that burned the Malice instantly.
"Is there a way to create Tear artificially?"
[Of course! As long as they know the method, they can seal an unpurified Spirit Power in a Talisman! That way, they can create an artificial Supernatural Disaster anytime. However…]
"However?"
Kai kept fending off the Malices and burned them as he talked with Amber. Even if he seemed like he underestimated them, he actually did not. He kept paying attention to where the Malice went and stopped as much as Malices he could; at the same time, he also listened to Amber.
[They will need a lot of unpurified Spirit Power to do that, which is around a fourth of your total Spirit Power.]
"That's it?" He asked, surprised. That was a really small amount for him.
[That's a lot, you know? Your reserve is now compared to 200 normal Slayers! Your Spirit Power reserve is now a similar amount to a weak Mythical creature instead of normal people!]
"Well… I don't know about that!" Once again, he swiped his arm, and a dozen Malices burned down to nothingness.
Only two or three Malices came out of the Tear every second now. It decreased considerably compared to when the Tear first appeared. At first, there were at least 10 Malices 2 to 3 meters tall, dropping to the ground every second.
More than a minute had passed since then, and Kai had fought in the sky for around 40 seconds. He glanced downward, and the Malices in the area had been taken care of, leaving nothing.
"I think our job is over right now. We also spent 3% of your Spirit Power in our fight just now."
[I agree. Let's leave the rest to the Oni and find this perpetrator. This Tear only lasts for a minute more at best, so it's clearly artificially created by someone.]
"As expected, huh? Let's tell Shuten Douji about that."
Kai began to descend slowly to the ground while flapping his feathered fire wings. As he descended, he also burned some Malices with Phoenix fire that danced around his wings. They danced like a snake and latched on the Malice before engulfing their whole bodies.
The sight was like a firework. His hair was unruffled due to the sweat he developed mid-fight, and it was dancing in the sky as the wind hit it.
He landed a bit away from Shuten Douji, and the Oni god noticed him immediately. His fire wings scattered around and turned into a beautiful fire bloom before disappearing.
"Oh, young man! You're really making a flashy move, aren't you?" She smirked at him, slinging her club over her shoulder. "That made my job easier! My subordinate also said thank you for helping, although she was also confused about where the Phoenix chick disappeared to, hahaha!"
"Hahaha…"
Shuten Douji's laugh was infectious. Kai laughed with her subconsciously. She had this aura of bringing people to do what she did.
Suddenly, she stopped. "Oops, I slipped back to my past self. Tehe~" With a cute movement, she put her hand on her head. The club in her hand was covered in light as it became smaller and eventually turned into a gold microphone she had used in the concert earlier.
"That's...?" Kai asked curiously. He looked at the microphone curiously and noticed a rune written on its shaft.
[Transformation Rune. That's quite an advanced technique only a top exorcist can do.]
"Something the Keikain family made for me. Quite convenient for something like this." Shuten Douji replied casually as she looked past Kai's shoulder. "Ooh? The Chief of this village is here."
Kai turned around, and indeed, Kirimaru and Ranga jumped from the collapsed building and kicked the Malice that had just dropped from the sky. The one Kirimaru kicked burst, while Ranga only managed to kick through its body. But fortunately, his kick landed on the Malice core, destroying it.
They landed a bit away from Kai and Shuten Douji, who silently moved beside him.
When Ranga saw him, his eyes widened in pleasant surprise as he pointed his hand.
"Ah! You're the one from that day!"
