The ancient teleportation formation here had no inherent connection to the teleportation formation of the Wolong Martial Sect.
However, with the treasure of the Wolong Martial Sect, even if one entered through this ancient teleportation formation, it could activate the power of the Wolong Martial Sect's teleportation formation, using that power to quickly return to the Wolong Martial Sect.
On the return journey, they still rode that rundown wooden boat, but Chu Feng's expression was grave.
He already knew the method to break the Great Calamity.
After returning to the Wolong Martial Sect, the Sect Master would use the full power of the entire sect to activate the grand formation, and then Chu Feng would command the formation's power to resist the Great Calamity.
As the saying went, whoever tied the bell must untie it. Since the Great Calamity appeared because of Chu Feng, Chu Feng would naturally be able to resolve it. After all, Chu Feng had experienced quite a few such situations before.
Chu Feng was not overly worried about breaking the Great Calamity.
The reason Chu Feng's expression was grave was because of Zi Ling.
He now understood why Zi Ling's soul had suddenly become so weak.
To explain this matter, one had to start with Zi Ling's talent.
Zi Ling's talent was actually decent, but her upper limit was not high. With her own talent alone, she originally would not have been able to reach her current realm.
The reason she had been able to reach such heights now was that Chu Feng's father had given Zi Ling assistance.
Chu Feng's father had left a special cultivation treasure within Zi Ling's Dantian.
This cultivation treasure was an ancient artifact from a bygone era, and even Chu Feng's father did not know its name.
All he knew was that this treasure could help Zi Ling and greatly enhance her talent.
Not only could she keep up with Chu Feng now, but she would not fall behind him in the future either.
If used properly, it was even possible that she could surpass Chu Feng.
According to what Zi Ling had said, the treasure looked like a blood-red triangular structure, but in reality, it more closely resembled a bizarre ancient tower.
If one looked carefully, one would discover that this bizarre blood-red ancient tower had three floors, each with a door.
Zi Ling could use this treasure to cultivate.
But there was a requirement.
That was, within a set time limit, she had to open all three doors in succession.
Otherwise... Zi Ling would suffer the backlash of this blood-red ancient tower.
Now, the time to open the first door had long since arrived.
But Zi Ling had been unable to open that first door.
As a result, the blood-red ancient tower had begun to damage Zi Ling's soul.
This was not the first time this had happened, but each occurrence was more severe than the last.
The blood-red ancient tower was reminding Zi Ling, and also warning her — if she could not open that door, she would be killed by the blood-red ancient tower.
Although the Sect Master could step in to help alleviate Zi Ling's condition...
If things continued this way, even the Sect Master would not be able to help Zi Ling.
Sooner or later, Zi Ling would be completely consumed by the backlash of the blood-red ancient tower and die.
Chu Feng had also asked Zi Ling whether his father had told her the method to control the blood-red ancient tower.
Chu Feng felt that since his father had chosen to help Zi Ling, he certainly would not have done something without a plan. There should have been a method to control it.
But Zi Ling said there was no method — she had to rely on her own ability.
Back then, Chu Feng's father had proposed several methods to help Zi Ling.
The blood-red ancient tower was the most effective, but also the most dangerous one.
It was Zi Ling herself who had insisted on choosing the blood-red ancient tower, refusing to accept any of the other methods.
Seeing how determined Zi Ling was, Chu Feng's father had agreed.
This was why, when the blood-red ancient tower's backlash struck Zi Ling, she apologized to Chu Feng and said it was her own fault.
That was indeed her own fault, after all... it was her own choice.
Nngh— Suddenly, Zi Ling let out another pained cry.
Looking over, Chu Feng and the others all showed expressions of tension.
Just by looking at Zi Ling's appearance, Chu Feng knew — the blood-red ancient tower's backlash had struck once again.
Seeing the situation was dire, the Sect Master immediately acted. She produced a gourd and poured a pill from within it.
