Alchemy Cauldron City.
Over the past twenty years, this city renowned for the Dao of Alchemy had gained another sight worth seeing.
It was neither the city lord's residence nor the grand gateway of some pill workshop.
It was a small courtyard.
The courtyard was modest, tucked away in an unremarkable alley in the eastern part of the city. From the outside, it looked no different from the other homes along the lane.
Yet cultivators passed through the alley every day. Some were merely passing by; others had come specifically for it.
But no one dared approach the door without permission.
Because a formation had been inscribed across the entire courtyard.
Twenty years ago, someone had placed a restriction here. At the time, he had only been in his teens, with a cultivation level of merely Nascent Soul.
A Spirit Transformation cultivator had once tried to probe it with divine sense, only to be struck by a bolt of lightning on the spot. He had been bedridden for three years, and even his cultivation had regressed.
Later, countless formation masters had come to study it, reaching a remarkably unanimous conclusion...
They could not understand it.
All they knew was that the thunder power within the formation was still circulating to this day.
And everyone in Alchemy Cauldron City said the person who had left that formation was Si Chen.
More than twenty years ago, Si Chen had left this courtyard to Wang Yan and his mother. That was no secret in Alchemy Cauldron City.
Afterward, Si Chen's name had grown ever more famous—from a legend of the Azure Profound Ranking, to Great Yin's Peerless King, and finally to someone who had ascended to the Immortal Realm.
Why would someone like that leave a courtyard to an obscure young rogue cultivator?
