The Ancient Battle Clan's clan chief naturally did not know that Chu Feng and the old cat were acquainted, nor was he aware of the changes within Chu Feng's heart.
He simply continued his account.
According to him, the old cat was a special cat demon.
He did not know where Zhan Haichuan had found this cat demon.
But this cat demon did indeed possess extraordinary power.
With Zhan Haichuan's help, the old cat had merged with the treasure's power and obtained the method to unlock it.
The gas the old cat was currently absorbing was nothing less than the process of unsealing the treasure.
Back in the day, the Ancient Battle Clan had exhausted the power of their formations to fight against the old cat and Zhan Haichuan.
They had believed the cat demon was killed, and Zhan Haichuan had fled wounded.
They never expected that the old cat had survived — and now it had returned.
"Clan Chief, could the person beside that cat demon be Zhan Haichuan?" an elder of the Ancient Battle Clan asked.
"No. Zhan Haichuan did have decent talent in martial cultivation, but his talent in barrier arts was unremarkable. There is no way he could have reached this level," the Ancient Battle Clan's clan chief replied.
"Clan Chief, do you know what level of cultivation that cat demon possessed back then?"
Chu Feng addressed the clan chief.
He felt that if what the Ancient Battle Clan's clan chief said was true, then since the old cat had survived, it must have sustained severe injuries back then.
Perhaps its cultivation had been damaged.
Otherwise, it would not have been so weak later on.
"That cat demon never displayed its cultivation, but it should have at least been comparable to Zhan Haichuan's — likely the late True God stage," the clan chief said.
Right at that moment, the Heavenly Dragon Spirit World Master beside the old cat produced an object.
It was a copper coin. In the blink of an eye, the coin transformed into something ten meters tall and descended in front of the old cat.
Simultaneously, the old cat shifted its hand seals, its eyes turning white. Its massive mouth opened wide, and it spewed forth a torrent of surging energy.
At the same time, the Heavenly Dragon Spirit World Master formed his own hand seals, and the copper coin began to spin rapidly.
The torrent of energy pierced through the center of the coin and was transformed into a pillar of light that hurtled toward the city wall.
BOOM— The piercing roar was heard clearly throughout the city. The towering black city wall shuddered violently.
Although the trembling soon subsided, the wall continued to vibrate ceaselessly, just as the bronze city wall had when it was under attack.
"Did that old cat convert the gas it absorbed from the treasure into power it can use for attacks?" Eggy asked.
"Yes."
"That formation is quite unusual as well."
Chu Feng was almost certain that the torrent the old cat had expelled from its mouth was indeed the gas it had absorbed from the treasure.
But the transformation would not have been possible without not only the old cat itself but also that copper coin formation.
So Chu Feng's gaze fixed upon the copper coin. It was a remarkable object, an ancient artifact.
But the formation was even more remarkable — with Chu Feng's current level of perception, he still could not fully grasp it.
"Father."
"Clan Chief."
At that moment, Zhan Mudan and Zhan Moli, along with everyone else in the Ancient Battle Clan, all turned their gaze toward the clan chief, their eyes filled with worry.
After all, this black city wall was their final barrier. If even this barrier fell, the Ancient Battle Clan would face the enemy head-on.
"All clan members, join me in repelling the invaders."
The Ancient Battle Clan's clan chief produced a command token. It released an invisible wave of barrier energy, transmitting a message.
With that, the clan chief soared into the sky, arriving before the black city wall.
He formed hand seals, and the void trembled.
