Zero smiled and said, "Your fear of Nan Yimu is nothing more than the Mu family's habit of using the trick of a cunning rabbit having three burrows. What if I could wipe out the Mu family in one fell swoop?"

Huang Tiangong raised his eyebrows slightly, "Lord Zero, forgive me for speaking frankly, if you can't completely exterminate the Mu family, I dare not cooperate with you."

Huang Tiangong knew very well that the Mu family was skilled in Feng Shui techniques. They could kill people without appearing near their target, and their methods were unpredictable.

As long as one member of the Mu family remained alive, they would be like vengeful ghosts, slowly grinding down the Huang family, one by one, within the Tiangong Sect.

Zero responded, "As long as you let the Mu family trade with me, I can find all of their people, and within an hour."

"Before I find everyone in the Mu family, you can choose to wait and see."

Huang Tiangong was finally satisfied, "I naturally know Lord Zero's abilities. If I can't deal with the Mu family even if they all appear in the Tiangong Sect, then wouldn't I have lived all these years in vain? Lord Zero, go ahead and do as you see fit! I will fully cooperate!"

As soon as Huang Tiangong's voice transmission ended, he said, "Lord Zero, the tea is cold. Would you like me to get you a fresh cup?"

Zero said indifferently, "My conditions will not change."

"I can tell you frankly that the Tiangong Sect needs *Qu Zhi Gui Shen* (Calculating Ghosts and Gods with Fingers) to further advance its Feng Shui secrets. As for me, I don't need the most profound Feng Shui techniques. If not Nan Yimu, then there's always Bei Yiye."

"Since the Tiangong Sect doesn't want to cooperate, then farewell."

"Lord Zero, please stay!" Huang Tiangong stood up and said, "Your conditions are a bit harsh. I need to discuss it with the Sect Leader. Please wait a moment."

Not long after Huang Tiangong turned and left, he returned with an old man with white hair and beard, "Lord Zero, this is our Sect Leader Mu."

Sect Leader Mu had no intention of currying favor with Zero. The two exchanged a few brief greetings and then got straight to the point. No matter how much Huang Tiangong bargained, Zero insisted on only one hour.

In the end, both sides had no choice but to sign a contract according to Zero's conditions, swearing an oath by blood.

Zero cut open her wrist with a dagger, dripped blood onto the contract, and then held her hand out to Shen Qingbai, who quickly bandaged the wound. Only then did Zero take out a secret technique from her body that was only as thick as a notebook.

Sect Leader Mu frowned and said, "This is *Qu Zhi Gui Shen* (Calculating Ghosts and Gods with Fingers)?"

Zero smiled and said, "Our blood oath has been witnessed by ghosts and gods. You don't think I can deceive ghosts and gods, do you?"

Sect Leader Mu then nodded and said, "In that case, please come with me!"

Sect Leader Mu led Zero to the front of a study and pointed to the dozen or so bookshelves inside, "These are the secret manuals of *Qian Nian Yi Mu* (Millennial Wood). Please examine them."

Zero only frowned slightly, and Mi Tianyue said angrily, "A room full of secret manuals? Are you kidding me?"

Sect Leader Mu laughed and said, "*Qian Nian Yi Mu* (Millennial Wood) encompasses everything: Feng Shui, vegetation, astronomy, geography, everything. To use *Qian Nian Yi Mu* (Millennial Wood), you need at least forty years of dedicated study. The strongest genius recorded in the Mu family also spent thirty years before gaining a preliminary understanding!"

Sect Leader Mu smiled and said, "Lord Zero won't regret it because of this, will you?"

Zero walked into the study without saying a word, "Qingbai, close the door."

Sect Leader Mu looked at the slowly closing door and said coldly, "Self-defeating!"

Huang Tiangong flattered and said, "Sect Leader is wise! No matter how good Zero's brain is, she can't possibly memorize this room full of secret manuals in an hour. When the time comes, she will have to sign another contract, and we can manipulate her as we please."

Sect Leader Mu sneered, "With such a thin secret manual, why do we need to sign another contract? Surely, my Mu family can memorize such a thin book in an hour, can't we?"

Huang Tiangong chuckled dryly, "Sect Leader is right. Everyone says that Zero is unfailingly resourceful, but this time she miscalculated."

After Sect Leader Mu turned and walked into a study, Huang Tiangong stood in the courtyard with a cold smile on his face. He could afford to wait an hour.

While Huang Tiangong was still pacing in the courtyard, he saw Sect Leader Mu come out, "Old Huang, come over here for a moment."

Huang Tiangong quickly walked into the study. Sect Leader Mu covered half of the secret manual with his hand and presented the lower section of the latter half of the manual to Huang Tiangong, "Take a look..."

Huang Tiangong quickly took a step back, "This... this isn't appropriate, is it?"

Sect Leader Mu said with a gloomy face, "I told you to look, so look. Where did all the nonsense come from? Tell me what you see?"

Huang Tiangong said in a low voice, "All algorithms under heaven, though different paths, lead to the same destination. But only three lineages can calculate the Great Dao. *Qu Zhi Gui Shen* (Calculating Ghosts and Gods with Fingers), initially one is like a ghost or god, knowing everything, further progress allows one to calculate ghosts and gods."

Huang Tiangong looked up and said, "Sect Leader, is there a problem with this?"

Sect Leader Mu said angrily, "Find me three disciples to come in."

Huang Tiangong casually summoned three disciples. Sect Leader Mu simply threw the secret manual in front of them, "All of you take a look. What do you see? What comes after the sentence 'Divine arts choose their master'?"

Only then did Huang Tiangong see that the part that had been covered by Sect Leader Mu's hand was: "Divine arts choose their master. Those chosen by divine arts can behold supernatural powers."

Two of the disciples shook their heads and said, "We didn't see anything."

Only one disciple said, "All algorithms under heaven, though different paths, lead to the same destination. But only three lineages can calculate the Great Dao..."
