"Don't worry, Brother Shao Yu, I know what I'm doing." Chu Feng replied silently.
Next, under the guidance of Zhan Moli and the elder, Chu Feng and the others came upon a black city wall that stretched across the sky.
That city wall was no ordinary structure — it not only sealed off heaven and earth, but every black brick was extraordinarily hard, and each was inscribed with rune patterns that clearly contained the power of a formation.
From those rune patterns, Chu Feng could tell that the formation's power was formidable.
And judging from the area the city wall covered, it most likely protected the entire ancient clan.
Such a vast area — the ancient clan might be one thing now, but in the era of their ancestors, they had truly been powerful.
"A city wall like this — and a Dragon-level Spirit World Master can still pose a threat?"
Chu Feng looked toward Zhan Moli. In his view, if that Dragon-level Spirit World Master could genuinely threaten this city wall, his strength was absolutely not merely first-rank Dragon-level, and probably beyond second-rank Dragon-level as well.
"Young Hero Chu Feng, this is the last protective barrier of our Ancient Battle Clan."
"There's another one further out. The one currently under attack is that outer wall."
As Zhan Moli spoke, the elder beside her gave an order, and the gate swung open.
Through the gate, the scene beyond appeared peaceful.
Chu Feng and the others pressed onward and soon heard bursts of booming rumble.
After advancing a stretch further, the distant sky was once again blocked by a structure spanning heaven and earth.
It was a city wall forged of bronze.
At that moment, the bronze wall radiated waves of light — the strengthening of a barrier formation.
Yet despite that barrier's reinforcement, the wall was still trembling ceaselessly.
The booming came from beyond the city wall.
As they drew closer, they could see that at regular intervals along the wall, there were round apertures, each fitted with one of the bronze spheres Chu Feng had just forged.
The barrier power reinforcing the wall emanated from those very bronze spheres.
However, at present, many of the spheres had developed cracks.
The number of cracked spheres was far more than a dozen.
At least within visible range, nearly a hundred bronze spheres showed cracks.
Every cracked sphere radiated barrier power far inferior to that of an intact one.
But the most alarming thing was that many positions where bronze spheres should have been installed were simply empty.
Either the formation had never been complete, or a great many bronze spheres had already shattered.
In short, this city wall's defensive power should have been extraordinary, but the mass absence of bronze spheres had drastically weakened it.
Before Chu Feng and the others could even approach, a group came to meet them, led by none other than Zhan Mudan.
But besides Zhan Mudan, several elders flanked her on both sides, every one of them at the True God Realm.
Many were unfamiliar faces — clearly elders of the Ancient Battle Clan who had been stationed here all along.
They had clearly heard of Chu Feng's exploits. Though they said nothing, they all studied him carefully; some wore expressions of respect, while others were visibly cautious.
"Young Hero Chu Feng, please help us."
"After we installed these bronze spheres, they failed to release any barrier power. We don't know why."
Zhan Mudan said.
Chu Feng said nothing. Instead, he shot straight toward a section of the city wall — he had already identified which bronze spheres were the ones he had just forged.
Upon reaching them, Chu Feng released his own barrier power and began forming hand seals.
In an instant, the bronze sphere erupted with powerful barrier energy that flowed into the formation wall.
Immediately after, Chu Feng flew to the other bronze spheres in rapid succession. In no time at all, he had activated every sphere he had forged.
With this surge of powerful barrier energy reinforcing it, even the trembling of the city wall diminished dramatically.
This further confirmed Chu Feng's suspicion.
This bronze city wall had never been weak — it was in fact sturdier than the black one.
