Zhou Dao transmigrated to a world where demons rampaged and Daoist laws ruled.
His sect was in straitened circumstances, and their property was on the brink of being demolished. Desperate, Zhou Dao had his eyes fixed on the coffin of the sect’s Grandmaster and decided to do something with it.
A voice rang, “D*mn! You are actually plotting to steal my skull. With your attitude, Sunset Mountain has a chance of reaching its heyday again!”
On that very night, the corpse of the Grandmaster moved! Moving forward, Zhou Dao would receive rewards whenever he offered up demonic beasts as sacrifices to the Grandmaster.
He offered up a 1000-year zombie as a sacrifice and received the Indestructible Body of Demon Refining.
He offered up a nine-tailed demon fox as a sacrifice and received a Fox Girl Puppet.
He offered up a demon turtle from the Eastern Sea as a sacrifice and received a high-power muscle massage gun.
…
For eons, countless Daoist members meditated on The Yellow Court Classic. For years to come, Zhou Dao harvested countless demonic beasts with no intention of burying them.
Many years later, in the same Daoist temple, Zhou Dao sat at the front door as he bore witness to the joy and the sorrow of all creations. He had seen birth, illness, death, and all sorts of bizarre phenomena. He put on a crooked grin as he said, “I offer up the heavens and the earth as a sacrifice.” 

I Became Invincible By Offering Up Sacrifices To My Sect's Grandmaster

"I don't quite understand," Zhou Dao shook his head.


Ever since he had entered the Heaven and Earth Realm, he had been diligently cultivating day and night. He had even pondered the power of the Twelve Demon Gods and had barely reached the Middle Heavenly Position. His true combat power should be comparable to the Great Heavenly Realm and, with various methods, he could even challenge the Upper Heaven Position. But that was all.


How could such power contend with the Abyss Ancestor?


"It's only natural, because you are still within this heaven and earth," the void figure suddenly said.


"What do you mean?" Zhou Dao asked, puzzled.


"A delicate instrument, even if you have the blueprints and tools to make it, cannot be made without the materials," the void figure spoke solemnly.
