That wisp of aura was extremely well-concealed — Chu Feng noticed it, but even Old Cat might not have.
But the most critical thing was the iron artifact itself.
The artifact resembled a crossbow bolt, aimed in a particular direction.
That was the direction where World Fan Immortal had been trapped earlier.
Moreover, the martial array contained overwhelming breaking force — it was clearly prepared for the sole purpose of rescuing World Fan Immortal.
Under normal circumstances, this martial array should have been triggered by now.
But it hadn't activated. It must have sensed that World Fan Immortal had already escaped, so it simply gave up on activating.
The array itself possessed such keen sensitivity — that alone showed just how exquisite this martial array was.
This was something that even many Spirit World Grandmasters couldn't achieve.
"My father — what kind of fortuitous encounter did he stumble upon to be able to cultivate martial arrays to this level?"
Chu Feng's exclamation couldn't be heard by Old Cat, but Eggy could hear it.
"Huh? Your father did this?"
Inside the Spirit World space, Eggy's beautiful eyes went wide.
This news was far too shocking, yet upon careful consideration, it was entirely plausible.
"Most likely. I sensed my father's aura."
"Besides, this martial array was made to rescue World Fan Immortal. Who else would do such a thing?" Chu Feng said.
"Right — after all, he did promise to rescue World Fan Immortal back then."
"So your father truly couldn't withstand that power back then, and left."
"But after his strength greatly increased, he came back."
"If he was able to rescue World Fan Immortal, though, why not just do it directly? Instead, he left behind this array and did all that work for no recognition?"
"Could it be that the power within Old Cat's bone is related to your father?"
"Yes, it must be so. Chu Feng, all of this really could have been your father's doing."
"Let's calculate the timing — when Old Cat felt the bone's power recover, it was after your father planted the guardian array inside your body."
"Your guardian array is already that powerful, so your father's subsequent strength must have been even greater."
"Your father really could have accomplished this."
"He entered this place originally seeking that treasure, only to discover it was nothing more than a pile of bones emanating resentment."
"Given your father's personality, he would definitely want to know the truth. So after investigating, he discovered the secret between the Ancient Battle Clan and Old Cat, and did a favor to help Old Cat recover."
"But to avoid any accidents, he waited until Old Cat had recovered before rescuing World Fan Immortal — that's why he set up this array."
"Chu Feng, do you think what I said is right?" Eggy asked.
"Eggy, you and I are thinking the same thing. I also believe this was my father's doing." Chu Feng sighed.
"But why didn't your father go all the way and just find Old Cat and bring him here?"
"Instead, he let Old Cat find his own way back?" Eggy asked.
"I don't know. My father must have had his reasons." Chu Feng said.
"Indeed, your father is quite mysterious. His strength is clearly formidable, yet in this vast cultivation world, there are no legends about him."
"It seems like all the news about your father is related to ancient ruins."
"Wow, your father is obviously a cultivator — why is he so obsessed with tomb raiding?" Eggy couldn't help but exclaim.
"What do you mean tomb raiding? That sounds terrible — it's called ruins exploration." Chu Feng corrected.
But Eggy wasn't convinced, grinning instead: "Sure, ruins exploration — abbreviated as tomb raiding."
Chu Feng was speechless, because it was indeed the same thing.
Looking at it this way, his father truly did love tomb raiding.
"Sigh, Chu Feng — if this was really your father's doing, then what level has your father actually reached? At that level, couldn't he save your mother?"
