The red thread wrapped around the tank is climbing up the steel bars of the building.

"The third bald man tampered with the property certificate, changing the height of the storage room by twenty centimeters, just to hide this 'underground well'."

Xiuxiu gripped her keychain tightly: "No wonder the property management checked the water meter last month and said my water usage was abnormal, so that's why..."

Her voice was suddenly interrupted by a rustling sound coming from the bottom of the well, like fingernails scratching at a ceramic pot.

Yuan Ying placed the Bagua mirror at the entrance of the well, with the edge of the mirror facing the north direction of the Ghost Gate.

"The Li trigram array at the bottom of the well borrows the 'human energy' of the entire building. The footsteps of the residents on each floor are like a 'soul-suppressing spell' for the fetal soul jar."

She pointed to the steel bars on the well wall and explained, "He smeared these steel bars with human blood and connected them to form a grid, so no one upstairs noticed there was a well underground. Chen Yan, try climbing down."

I was taken aback.

"What are you waiting for? There's no danger, climb down!"

Seeing that I didn't say anything, Yuan Ying urged me impatiently.

Since she said there would be no danger, I'll just climb down.

However, as soon as I went down a little, I felt a chill come from the soles of my feet and went straight to the top of my head.

Traces of cinnabar adhering to the surface of the steel bars.

The pottery jar at the bottom of the well is fixed between the load-bearing beams by steel bars. The red rope at the mouth of the jar is connected to the red thread behind Xiuxiu's ear by steel bars, forming a "steel bar soul-guiding array".

Ironically, the steel bars in modern buildings have become the best medium for transmitting evil magic.

"Chen Yan, look at the bottom of the jar!"

Yuan Ying's voice came from above, and the light spot of the bone-revealing mirror fell on the bottom of the pottery jar, where the signature of the Half-Immortal was engraved.

"In 1931, a hidden well was built on the foundation of a commercial building, with steel bars as its skeleton and human blood as its guide, taking thirty years to complete..."

I had just looked down when Xiuxiu suddenly pointed at the mirror and exclaimed, "The hand in the jar is moving!"

Is the hand moving inside the jar?

What the heck?

I looked up in a panic and saw black mist churning in the mirror, with countless baby fingerprints climbing up the steel bars.

Each time a steel bar is passed, a blood-red Li trigram is left behind.

It was then that I realized that the steel structure of the entire building had been rewritten into a giant "soul jar" by the sorcery of the half-immortal.

And we are living in this reinforced concrete "living coffin".
